CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash soap
and a soft cloth. Do not use rough or hard cloths. Do not
scratch or poke the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
 Ensure that the front and rear fascia/bumper are free
of snow, ice, mud, dirt, and debris to keep the
ParkSense system operating properly.
 Construction equipment, large trucks, and other vibra -
tions could affect the performance of ParkSense.
 When you turn ParkSense off, the instrument cluster
will display “PARKSENSE OFF.” Furthermore, once you
turn ParkSense off, it remains off until you turn it on
again, even if you cycle the ignition key.
 When you move the gear selector to the REVERSE posi -
tion and ParkSense is turned off, the instrument
cluster will display “PARKSENSE OFF” for as long as the
vehicle is in REVERSE.
 ParkSense, when on, will reduce the volume of the
radio when it is sounding a tone.
 Clean the ParkSense sensors regularly, taking care not
to scratch or damage them. The sensors must not be
covered with ice, snow, slush, mud, dirt or debris.
Failure to do so can result in the system not working
properly. The ParkSense system might not detect an
obstacle behind or in front of the appropriate fascia/ bumper, or it could provide a false indication that an
obstacle is behind or in front of the appropriate fascia/
bumper.
 Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers, trailer
hitches, etc., are placed within 12 inches (30 cm) from
the rear fascia/bumper. Failure to do so can result in
the system misinterpreting a close object as a sensor
problem, causing the “PARKSENSE UNAVAILABLE
WIPE REAR SENSORS” message to be displayed in the
instrument cluster.
 ParkSense should be disabled when the liftgate is in
the open position. An opened liftgate could provide a
false indication that an obstacle is behind the vehicle.
 There may be a delay in the object detection rate if the
object is moving. This may cause the automatic braking
application to be delayed.
WARNING!
Drivers must be careful when backing up even when
using ParkSense. Always check carefully behind your
vehicle, look behind you, and be sure to check for
pedestrians, animals, other vehicles, obstructions,
and blind spots before backing up. You are respon -
sible for safety and must continue to pay attention to
your surroundings. Failure to do so can result in
serious injury or death.
 Before using ParkSense, it is strongly recommended
that the ball mount and hitch ball assembly be
disconnected from the vehicle when the vehicle is
not used for towing. Failure to do so can result in
injury or damage to vehicles or obstacles because
the hitch ball will be much closer to the obstacle than
the rear fascia when the vehicle sounds the contin -
uous tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on its size
and shape, giving a false indication that an obstacle
is behind the vehicle.
CAUTION!
 ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below the
sensors will not be detected when they are in close
proximity.
 The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when an
obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.
WARNING!

STARTING AND OPERATING137

PARKSENSE ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED

The ParkSense Active Park Assist system is intended to
assist the driver during parallel and perpendicular parking
maneuvers by identifying a proper parking space,
providing audible/visual instructions, and controlling the
steering wheel. The ParkSense Active Park Assist system
is defined as “semi-automatic” since the driver maintains
control of the accelerator, gear selector and brakes.
Depending on the driver's parking maneuver selection, the
ParkSense Active Park Assist system is capable of
maneuvering a vehicle into a parallel or a perpendicular
parking space on either side (i.e., driver side or passenger
side).
NOTE:
The driver is always responsible for controlling the
vehicle, responsible for any surrounding objects, and
must intervene as required.
 The system is designed to assist the driver and not to
substitute the driver.
 During a semi-automatic maneuver, if the driver
touches the steering wheel after being instructed to
remove their hands from the steering wheel, the
system will cancel, and the driver will be required to
manually complete the parking maneuver.
 The system may not work in all conditions (e.g. environ -
mental conditions such as heavy rain, snow, etc., or if
searching for a parking space that has surfaces that
will absorb the ultrasonic sensor waves). 
New vehicles from the dealership must have at least
30 miles (48 km) accumulated before the ParkSense
Active Park Assist system is fully calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature.
 The use of wheels and tires that are different size to the
original equipment could affect the operation of the
system.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST

and disabled with the ParkSense Active Park Assist switch,
located on the switch panel below the Uconnect display.
To enable or disable the ParkSense Active Park
Assist system, push the ParkSense Active Park
Assist switch once (LED turns on). Pushing the
switch a second time will disable the system
(LED turns off).
The ParkSense Active Park Assist system will turn off
automatically for any of the following conditions:
 Parking maneuver is completed.
 Vehicle speed is greater than 18 mph (30 km/h) when
searching for a parking space.
 Vehicle speed is greater than 5 mph (7 km/h) during
active steering guidance into the parking space. 
Steering wheel is touched during active steering guid -
ance into the parking space.
 ParkSense switch is pushed.
 The driver’s door is opened.
 The liftgate is opened.
 Electronic Stability Control/Anti-Lock Braking System
intervention.
The ParkSense Active Park Assist system will allow a
maximum numbers of shifts between DRIVE and
REVERSE. If the maneuver cannot be completed within
eight shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
The ParkSense Active Park Assist system will only operate
and search for a parking space when the following
conditions are present:
 The gear selector is in DRIVE.
 The ignition is in the RUN position.
 The ParkSense Active Park Assist switch is activated.
 The driver’s door is closed.
 The liftgate is closed.
 Vehicle speed is less than 15 mph (25 km/h).
 The outer surface and the underside of the front and
rear fascias/bumpers are clean and clear of snow, ice,
mud, dirt or other obstructions.
When pushed, the LED on the ParkSense Active Park
Assist switch will blink momentarily, and then the LED will
turn off if any of the above conditions are not present.

Move Backward Into Parallel Parking Space
Move Backward Into Perpendicular Parking Space

The system may instruct several more gear shifts (DRIVE
and REVERSE), with hands off of the steering wheel,
before instructing the driver to check surroundings and
complete the parking maneuver. When the vehicle is in the parking position, the maneuver
is complete and the driver will be instructed to check the
vehicle's parking position, then shift the vehicle into PARK.
The message "Active ParkSense Complete - Check Parking
Position" will be displayed momentarily.
NOTE:

It is the driver's responsibility to use the brake and
accelerator during the semi-automatic parking
maneuver.
 It is the driver's responsibility to use the brake and stop
the vehicle. The driver should check their surroundings
and be prepared to stop the vehicle either when
instructed to, or when driver intervention is required.
 When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.
 The ParkSense Active Park Assist system will allow a
maximum number of shifts between DRIVE and
REVERSE. If the maneuver cannot be completed within
six shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
 The system will cancel the maneuver if the vehicle
speed exceeds 5 mph (7 km/h) during active steering
guidance into the parking space. The system will
provide a warning to the driver at 3 mph (5 km/h) that
tells them to slow down. The driver is then responsible
for completing the maneuver if the system is canceled.
 If the system is canceled during the maneuver for any
reason, the driver must take control of the vehicle.
WARNING!
Drivers must be careful when performing parallel or
perpendicular parking maneuvers even when using the
ParkSense Active Park Assist system. Always check
carefully behind and in front of your vehicle, look
behind and in front of you, and be sure to check for
pedestrians, animals, other vehicles, obstructions, and
blind spots before backing up and moving forward. You
are responsible for safety and must continue to pay
attention to your surroundings. Failure to do so can
result in serious injury or death.
CAUTION!
The ParkSense Active Park Assist system is only a
parking aid and it is unable to recognize every
obstacle, including small obstacles. Parking curbs
might be temporarily detected or not detected at all.
Obstacles located above or below the sensors will
not be detected when they are in close proximity.
 The vehicle must be driven slowly when using the
ParkSense Active Park Assist system in order to be
able to stop in time when an obstacle is detected. It
is recommended that the driver looks over his/her
shoulder when using the ParkSense Active Park
Assist system.

SAFETY189
Electronic Stability Control (ESC)
ESC enhances directional control and stability of the
vehicle under various driving conditions. ESC corrects for
oversteering or understeering of the vehicle by applying
the brake of the appropriate wheel(s) to assist in
counteracting these conditions. Engine power may also be
reduced to help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more than
appropriate for the steering wheel position.
 Understeer — when the vehicle is turning less than
appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the vehicle
path intended by the driver and compares it to the actual
path of the vehicle. When the actual path does not match
the intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting the oversteer
or understeer condition.
The ESC Activation/Malfunction Indicator Light located in
the instrument cluster will start to flash as soon as the ESC
system becomes active. The ESC Activation/Malfunction
Indicator Light also flashes when the TCS is active. If the ESC Activation/Malfunction Indicator Light begins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:When driving with snow chains, or when starting off in
deep snow, sand, or gravel, it may be desirable to allow
more wheel spin. This can be accomplished by momen
-
tarily pushing the ESC OFF button to enter partial mode
“Partial Off” mode. Once the situation requiring “Partial
Off” mode is overcome, turn ESC back on by momentarily
pushing the ESC OFF button. This may be done while the
vehicle is in motion.
WARNING!

Many factors, such as vehicle loading, road conditions
and driving conditions, influence the chance that wheel
lift or rollover may occur. ERM cannot prevent all wheel
lift or rollovers, especially those that involve leaving the
roadway or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must never be
exploited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

WARNING!

 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle, nor
can it increase the traction afforded by prevailing road
conditions. ESC cannot prevent accidents, including
those resulting from excessive speed in turns, driving
on very slippery surfaces, or hydroplaning. ESC also
cannot prevent accidents resulting from loss of vehicle
control due to inappropriate driver input for the condi -
tions. Only a safe, attentive, and skillful driver can
prevent accidents. The capabilities of an ESC
equipped vehicle must never be exploited in a reckless
or dangerous manner which could jeopardize the
user’s safety or the safety of others.

 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

192SAFETY
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. Note that TSC cannot
stop all trailers from swaying. Always use caution when
towing a trailer and follow the trailer tongue weight
recommendations
Úpage 147.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM) —
I
F EQUIPPED
The BSM system uses two radar sensors, located inside
the rear fascia/bumper, to detect highway licensable
vehicles (automobiles, trucks, motorcycles, etc.) that
enter the blind spot zones from the rear/front/side of the
vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear and enters standby mode when the vehicle is
in PARK (P).
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.7 m). The zone
length starts at the outside rearview mirror and extends
approximately 10 ft (3 m) beyond the rear fascia/bumper
of the vehicle. The BSM system monitors the detection
zones on both sides of the vehicle when the vehicle speed
reaches approximately 6 mph (10 km/h) or higher and will
alert the driver of vehicles in these areas.
NOTE:
 The BSM system DOES NOT alert the driver about
rapidly approaching vehicles that are outside the
detection zones. 
The BSM system detection zone DOES NOT change if
your vehicle is towing a trailer. Therefore, visually verify
the adjacent lane is clear for both your vehicle and
trailer before making a lane change. If the trailer or
other object (i.e., bicycle, sports equipment) extends
beyond the side of your vehicle, this may result in false
detections. The BSM Warning Light may even remain
illuminated the entire time the vehicle is in a forward
gear.
 The Blind Spot Monitoring (BSM) system may experi -
ence dropouts (blinking on and off) of the side mirror
warning indicator lights when a motorcycle or any small
object remains at the side of the vehicle for extended
periods of time (more than a couple of seconds).
The area on the rear fascia/bumper where the radar
sensors are located must remain free of snow, ice, and
dirt/road contamination so that the BSM system can
function properly. Do not block the area of the rear fascia/
bumper where the radar sensors are located with foreign
objects (bumper stickers, bicycle racks, etc.).

Sensor Location

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

23_RUP_OM_EN_USC_t.book Page 192

SAFETY193
If the system detects degraded performance due to
contamination or foreign objects, a message will warn you
of a blocked sensor and the warning indicators in side
view mirrors will be on. The warning indicators will remain
illuminated until blockage clearing conditions are met.
First clear the fascia/bumper area around the sensors of
the blockage. After removing the blockage, cycle the
ignition from on to off and then back on again to reset the
system.
If the blockage message is still present after cycling the
ignition and driving in traffic, check again for a blockage.
The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM Warning Light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume
Úpage 194.

Warning Light Location

The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries. Entering From The Side
Vehicles that move into your adjacent lanes from either
side of the vehicle.

Side Monitoring

Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative
speed of less than 30 mph (48 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative speed
less than 15 mph (24 km/h) and the vehicle remains in
the blind spot for approximately 1.5 seconds, the warning
light will be illuminated. If the difference in speed between
the two vehicles is greater than 15 mph (24 km/h), the
warning light will not illuminate.

Overtaking/Approaching
Overtaking/Passing

23_RUP_OM_EN_USC_t.book Page 193

194SAFETY
The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, snow banks, car washes, etc. However,
occasionally the system may alert on such objects. This is
normal operation and your vehicle does not require
service.
The BSM system will not alert you of objects that are
traveling in the opposite direction of the vehicle in
adjacent lanes
Úpage 312.

Opposing Traffic

Rear Cross Path (RCP)
RCP is intended to aid the driver when backing out of
parking spaces where their vision of oncoming vehicles
may be blocked. Proceed slowly and cautiously out of the
parking space until the rear end of the vehicle is exposed.
The RCP system will then have a clear view of the cross
traffic and if an oncoming vehicle is detected, alert the
driver.

RCP Detection Zones

RCP monitors the rear detection zones on both sides of
the vehicle, for objects that are moving toward the side of
the vehicle with a minimum speed of approximately 3 mph
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:In a parking lot situation, oncoming vehicles can be
blocked by vehicles parked on either side. If the sensors
are blocked by other structures or vehicles, the system will
not be able to alert the driver. Additionally, if your vehicle is obscured by a flat object on one side the system can
false alert on vehicles approaching from the opposite
direction.
When RCP is on and the vehicle is in REVERSE (R), the
driver is alerted using both the visual and audible alarms,
including reducing the radio volume.
Blind Spot Modes
Three selectable modes of operation are available in the
Uconnect system.
Blind Spot Alert Lights Only — Default Setting
When operating in Blind Spot Alert mode, the BSM system
will provide a visual alert in the appropriate side view
mirror based on a detected object. However, when the
system is operating in Rear Cross Path (RCP) mode, the
system will respond with both visual and audible alerts
when a detected object is present. Whenever an audible
alert is requested, the radio is muted.
WARNING!
The Blind Spot Monitoring system is only an aid to help
detect objects in the blind spot zones. The BSM system
is not designed to detect pedestrians, bicyclists, or
animals. Even if your vehicle is equipped with the BSM
system, always check your vehicle’s mirrors, glance
over your shoulder, and use your turn signal before
changing lanes. Failure to do so can result in serious
injury or death.
WARNING!
Rear Cross Path Detection (RCP) is not a back up aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using
RCP. Always check carefully behind your vehicle, look
behind you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and blind spots
before backing up. Failure to do so can result in serious
injury or death.

23_RUP_OM_EN_USC_t.book Page 194

SAFETY195
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
time, both the visual and audible alerts will be issued. In
addition to the audible alert the radio (if on) will also be
muted.
NOTE:Whenever an audible alert is requested by the BSM
system, the radio is also muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
is also muted. Turn/hazard signal status is ignored; the
RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off there will be no visual
or audible alerts from either the BSM or RCP systems.
NOTE:
The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started the previously stored mode will be recalled and
used.
 The BSM system can work in conjunction with the
KeySense function of the vehicle (if equipped)
Úpage 98.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION — IF EQUIPPED
FCW with Mitigation provides the driver with audible
warnings, visual warnings (within the instrument cluster
display), and may apply a brake jerk to warn the driver
when it detects a potential frontal collision. The warnings
and limited braking are intended to provide the driver with
enough time to react, avoid or mitigate the potential
collision.
NOTE:FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings
and may provide a brake jerk warning.
If the driver does not take action based upon these
progressive warnings, then the system will provide a
limited level of active braking to help slow the vehicle and
mitigate the potential forward collision. If the driver reacts
to the warnings by braking and the system determines
that the driver intends to avoid the collision by braking but
has not applied sufficient brake force, the system will
compensate and provide additional brake force as
required.
If a FCW with Mitigation event begins at a speed below
37 mph (60 km/h), the system may provide the maximum
braking possible to mitigate the potential forward
collision. If the Forward Collision Warning with Mitigation
event stops the vehicle completely, the system will hold
the vehicle at standstill for two seconds and then release the brakes. If a pedestrian is encountered in the path at
the same speed threshold, the system will attempt to
bring the vehicle to a stop.

FCW Message

When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated
Úpage 312.
NOTE:

The minimum speed for FCW activation is 1 mph
(2 km/h).
 The FCW alerts may be triggered on objects other than
vehicles such as guardrails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
 It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within a key cycle, the Active Braking portion of FCW will
be deactivated until the next key cycle.

198SAFETY
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low-pressure warning limit for
any reason, including low temperature effects and natural
pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not turn
off until the tire pressure is at or above the recommended
cold placard pressure. Once the low tire pressure warning
(TPMS Warning Light) illuminates, you must increase the
tire pressure to the recommended cold placard pressure
in order for the TPMS Warning Light to turn off.
The system will automatically update and the TPMS
Warning Light will turn off once the system receives the
updated tire pressures. The vehicle may need to be driven
for up to 20 minutes above 15 mph (24 km/h) in order for
the TPMS to receive this information.
For example, your vehicle may have a recommended cold
(parked for more than three hours) placard pressure of
33 psi (227 kPa). If the ambient temperature is 68°F
(20°C) and the measured tire pressure is 28 psi
(193 kPa), a temperature drop to 20°F (-7°C) will
decrease the tire pressure to approximately 24 psi
(165 kPa). This tire pressure is low enough to turn on the
TPMS Warning Light. Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi (193 kPa), but the
TPMS Warning Light will still be on. In this situation, the
TPMS Warning Light will turn off only after the tires are
inflated to the vehicle’s recommended cold placard
pressure value
Úpage 312.
NOTE:When filling warm tires, the tire pressure may need to be
increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.NOTE:
The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire failure
or condition.
 The TPMS should not be used as a tire pressure gauge
while adjusting your tire pressure.
 Driving on a significantly underinflated tire causes the
tire to overheat and can lead to tire failure. Underinfla -
tion also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping ability.
 The TPMS is not a substitute for proper tire mainte -
nance, and it is the driver’s responsibility to maintain
correct tire pressure using an accurate tire pressure
gauge, even if underinflation has not reached the level
to trigger illumination of the TPMS Warning Light.
 Seasonal temperature changes will affect tire pres -
sure, and the TPMS will monitor the actual tire pres -
sure in the tire.
Premium System
The Tire Pressure Monitoring System (TPMS) uses wireless
technology with wheel rim mounted electronic sensors to
monitor tire pressure levels. Sensors, mounted to each
wheel as part of the valve stem, transmit tire pressure
readings to the receiver module.
NOTE:It is particularly important for you to check the tire
pressure in all of the tires on your vehicle monthly and to
maintain the proper pressure.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warning
have been established for the tire size equipped on
your vehicle. Undesirable system operation or sensor
damage may result when using replacement equip -
ment that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on after -
market wheels and may contribute to a poor overall
system performance or sensor damage. Customers
are encouraged to use Original Equipment Manufac -
turer (OEM) wheels to ensure proper TPMS feature
operation.
 Using aftermarket tire sealants may cause the Tire
Pressure Monitoring System (TPMS) sensor to
become inoperable. After using an aftermarket tire
sealant it is recommended that you take your vehicle
to an authorized dealer to have your sensor function
checked.
 After inspecting or adjusting the tire pressure always
reinstall the valve stem cap. This will prevent mois -
ture and dirt from entering the valve stem, which
could damage the TPMS sensor.

23_RUP_OM_EN_USC_t.book Page 198

SAFETY199
The TPMS consists of the following components:
Receiver module
 Four Tire Pressure Monitoring System sensors
 Various Tire Pressure Monitoring System messages,
which display in the instrument cluster
 Tire Pressure Monitoring System Warning Light
SERVICE TPMS WARNING
When a system fault is detected, the Tire Pressure
Monitoring System (TPMS) Warning Light will flash on and
off for 75 seconds and then remain on solid. The system
fault will also sound a chime. In addition, the instrument
cluster will display a "SERVICE TPM SYSTEM" message for
a minimum of five seconds and then display dashes (--) in
place of the pressure value to indicate which sensor is not
being received.
If the ignition is cycled, this sequence will repeat, providing
the system fault still exists. If the system fault no longer
exists, the TPMS Warning Light will no longer flash, and
the “SERVICE TPM SYSTEM” message will no longer
display, and a pressure value will display in place of the
dashes. A system fault can occur due to any of the
following:
Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors
 Installing some form of aftermarket window tinting that
affects radio wave signals
 Lots of snow or ice around the wheels or wheel hous -
ings 
Using tire chains on the vehicle
 Using wheels/tires not equipped with TPMS sensors
Vehicles With Compact Spare — If Equipped

1. The compact spare tire does not have a Tire Pressure Monitoring System sensor. Therefore, the
TPMS will not monitor the pressure in the compact
spare tire.

2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure
warning limit, upon the next ignition cycle, the TPMS
Warning Light will remain on and a chime will sound.
In addition, the graphic in the instrument cluster will
still display a different color pressure value.
3. After driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the TPMS Warning Light will flash
on and off for 75 seconds and then remain on solid.
In addition, the instrument cluster will display a
“SERVICE TPM SYSTEM” message for five seconds
and then display dashes (--) in place of the pressure
value.
4. For each subsequent ignition cycle, a chime will sound, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on solid, and the
instrument cluster will display a “SERVICE TPM
SYSTEM” message for five seconds and then display
dashes (- -) in place of the pressure value.
5. Once you repair or replace the original road tire and reinstall it on the vehicle in place of the compact
spare, the TPMS will update automatically. In
addition, the TPMS Warning Light will turn off and the
graphic in the instrument cluster will display a new
pressure value instead of dashes (--), as long as no tire pressure is below the low-pressure warning limit
in any of the four active road tires. The vehicle may
need to be driven for up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to receive this
information.
TIRE PRESSURE MONITORING SYSTEM LOW
PRESSURE WARNINGS
The TPMS Warning Light will illuminate in the
instrument cluster and a chime will sound
when tire pressure is low in one or more of the
four active road tires. In addition, the
instrument cluster will display an "Inflate to XX" message
and a graphic showing the pressure values of each tire
with the low tire pressure values in a different color.
