ESC Activation/Malfunction Indicator Light
And ESC OFF Indicator Light
The ESC Activation/Malfunction Indicator Light
in the instrument cluster will come on when the
ignition is placed in the ON/RUN mode. It
should go out with the engine running. If the
ESC Activation/Malfunction Indicator Light comes on
continuously with the engine running, a malfunction has
been detected in the ESC system. If this light remains on
after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as possible to have the problem diagnosed and corrected. The ESC Activation/Malfunction Indicator Light starts to
flash as soon as the tires lose traction and the ESC system
becomes active. The ESC Activation/Malfunction Indicator
Light also flashes when 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.
The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light and the
ESC OFF Indicator Light come on momentarily each
time the ignition is placed in the ON/RUN mode.
 Each time the ignition is placed in the ON/RUN mode,
the ESC system will be on even if it was turned off previ -
ously.
 The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive following the maneuver
that caused the ESC activation.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road driving
while in 4WD Low. HDC maintains vehicle
speed while descending hills during various
driving situations. HDC controls vehicle speed
by actively controlling the brakes. HDC Has Three States:

1. Off (feature is not enabled and will not activate).

2. Enabled (feature is enabled and ready but activation
conditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable HDC:
 The driveline is in 4WD Low.
 The vehicle speed is below 5 mph (8 km/h).
 The parking brake is released.
 The driver door is closed.
Activating HDC
Once HDC is enabled it will activate automatically if driven
down a grade of sufficient magnitude. The set speed for
HDC is selectable by the driver, and can be adjusted by
using the gear shift +/-. The following summarizes the
HDC set speeds:
WARNING!
 When in “Partial Off” mode, the TCS functionality of
ESC, except for the limited slip feature described in
the TCS section, has been disabled and the ESC OFF
Indicator Light will be illuminated. When in “Partial
Off” mode, the engine power reduction feature of
TCS is disabled, and the enhanced vehicle stability
offered by the ESC system is reduced.
 Trailer Sway Control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.

HDC Target Set Speeds
P = No set speed. HDC may be enabled but will not
activate.
 R = 0.6 mph (1 km/h)
 N = 1.2 mph (2 km/h)
 D = 0.6 mph (1 km/h)
 1st = 0.6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5.0 mph (8 km/h)
 9th = 5.6 mph (9 km/h) – If Equipped
NOTE:During HDC the +/- shifter input is used for HDC target
speed selection, but will not affect the gear chosen by the
transmission. When actively controlling HDC the trans -
mission will shift appropriately for the driver-selected set
speed and corresponding driving conditions.
Driver Override
The driver may override HDC activation with throttle or
brake application at any time.
Deactivating HDC
HDC will be deactivated but remain available if any of the
following conditions occur:
 The driver overrides HDC set speed with throttle or
brake application.
 The vehicle speed exceeds 20 mph (32 km/h) but
remains below 40 mph (64 km/h). 
The vehicle is on a downhill grade of insufficient magni -
tude, is on level ground, or is on an uphill grade.
 The vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
 The driver pushes the HDC switch.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(HDC exits immediately).
 HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC
switch has an LED icon, which offers feedback to the
driver about the state HDC is in.
 The cluster icon and switch light will illuminate and
remain on solid when HDC is enabled or activated. This
is the normal operating condition for HDC.
 The cluster icon and switch light will flash for several
seconds, then extinguish when the driver pushes the
HDC switch but enable conditions are not met.
 The cluster icon and switch light will flash for several
seconds, then extinguish when HDC disables due to
excess speed.
 The cluster icon and switch light will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
Hill Start Assist (HSA)
HSA is designed to mitigate roll back from a complete stop
while on an incline. If the driver releases the brake while
stopped on an incline, HSA will continue to hold the brake
pressure for a short period. If the driver does not apply the
throttle before this time expires, the system will release
brake pressure and the vehicle will roll down the hill as
normal.
The following conditions must be met in order for HSA to
activate:
The feature must be enabled.
 The vehicle must be stopped.
 The parking brake must be off.
 The driver door must be closed.
 The vehicle must be on a sufficient grade.
 The gear selection must match vehicle uphill direction
(i.e., vehicle facing uphill is in forward gear; vehicle
backing uphill is in REVERSE (R) gear).
 HSA will work in REVERSE gear and all forward gears.
The system will not activate if the transmission is in
PARK (P) or NEUTRAL (N).
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.

23_WS_OM_EN_USC_t.book Page 244

SAFETY245
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
If disabling HSA using your instrument cluster display,
see
Úpage 99 for further information.
 If disabling HSA using Uconnect Settings, see
Úpage 197 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll back while
towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet conditions.
It will periodically apply a small amount of brake pressure
to remove any water buildup on the front brake rotors. It
functions when the windshield wipers are in LO or HI
speed. When RBS is active, there is no notification to the
driver and no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full braking
during emergency braking situations. It anticipates when
an emergency braking situation may occur by monitoring
how fast the throttle is released by the driver. The
Electronic Brake Controller (EBC) will prepare the brake
system for a panic stop.
Selec-Speed Control (SSC) — If Equipped
Selec-Speed Control (SSC) is intended for
off-road driving in 4WD Low only. SSC
maintains vehicle speed by actively controlling
engine torque and brakes.
SSC has three states:

1. Off (feature is not enabled and will not activate)

2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is actively overriding
with brake or throttle application)
3. Active (feature is enabled and actively controlling vehicle speed)
Enabling SSC
SSC is enabled by pushing the SSC switch, but the
following conditions must also be met to enable SSC:
 The driveline is in 4WD Low.
 The vehicle speed is below 5 mph (8 km/h).
 The parking brake is released.
 The driver door is closed.
 The driver is not applying throttle.
Activating SSC
Once SSC is enabled it will activate automatically once the
following conditions are met:
 Driver releases throttle.
 Driver releases brake.
 Transmission is in any selection other than PARK.
 Vehicle speed is below 20 mph (32 km/h).WARNING!
There may be situations where the Hill Start Assist
(HSA) will not activate and slight rolling may occur, such
as on minor hills or with a loaded vehicle, or while
pulling a trailer. HSA is not a substitute for active driving
involvement. It is always the driver’s responsibility to be
attentive to distance to other vehicles, people, and
objects, and most importantly brake operation to
ensure safe operation of the vehicle under all road
conditions. Your complete attention is always required
while driving to maintain safe control of your vehicle.
Failure to follow these warnings can result in a collision
or serious personal injury.
WARNING!
If you use a trailer brake controller with your trailer,
the trailer brakes may be activated and deactivated
with the brake switch. If so, there may not be enough
brake pressure to hold both the vehicle and the
trailer on a hill when the brake pedal is released. In
order to avoid rolling down an incline while resuming
acceleration, manually activate the trailer brake or
apply more vehicle brake pressure prior to releasing
the brake pedal.
 HSA is not a parking brake. Always apply the parking
brake fully when exiting your vehicle. Also, be certain
to place the transmission in PARK.
 Failure to follow these warnings can result in a colli -
sion or serious personal injury.

246SAFETY
The set speed for SSC is selectable by the driver, and can
be adjusted by using the gear shift +/-. Additionally, the
SSC set speed may be reduced when climbing a grade and
the level of set speed reduction depends on the
magnitude of grade. The following summarizes the SSC
set speeds:
SSC Target Set Speeds
1st = .6 mph (1 km/h)
 2nd = 1.2 mph (2 km/h)
 3rd = 1.8 mph (3 km/h)
 4th = 2.5 mph (4 km/h)
 5th = 3.1 mph (5 km/h)
 6th = 3.7 mph (6 km/h)
 7th = 4.3 mph (7 km/h)
 8th = 5 mph (8 km/h)
 9th = 5.6 mph (9 km/h) – If Equipped
 REVERSE = .6 mph (1 km/h)
 NEUTRAL = 1.2 mph (2 km/h)
 PARK = SSC remains enabled but not active
NOTE:
During SSC the +/- shifter input is used for SSC target
speed selection but will not affect the gear chosen by
the transmission. While actively controlling SSC the
transmission will shift appropriately for the
driver-selected set speed and corresponding driving
conditions.
 SSC performance is influenced by the Select-Terrain
mode. This difference may be notable to the driver and
may be perceived as a varying level of aggressiveness. Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:

Driver overrides SSC set speed with throttle or brake
application
 Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h)
 Vehicle is shifted to PARK
Disabling SSC
SSC will deactivate and be disabled if any of the following
conditions occur:
 The driver pushes the SSC switch.
 The driveline is shifted out of 4WD Low.
 The parking brake is applied.
 The driver door opens.
 The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
 The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offers feedback to the driver
about the state SSC is in.
 The cluster icon and switch light will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC. 
The cluster icon and switch light will flash for several
seconds then extinguish when the driver pushes the
SSC switch but enable conditions are not met.
 The cluster icon and switch light will flash for several
seconds then extinguish when SSC disables due to
excess speed.
 The cluster icon and switch light will flash then extin -
guish when SSC deactivates due to overheated brakes.
Traction Control System (TCS)
The TCS monitors the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the TCS may apply
brake pressure to the spinning wheel(s) and/or reduce
engine power to provide enhanced acceleration and
stability. A feature of the TCS, Brake Limited Differential
(BLD) functions similarly to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This will
allow more engine power to be applied to the wheel that is
not spinning. BLD may remain enabled even if the TCS and
Electronic Stability Control (ESC) are in reduced modes.
WARNING!
SSC is only intended to assist the driver in controlling
vehicle speed when driving in off-road conditions. The
driver must remain attentive to the driving conditions
and is responsible for maintaining a safe vehicle speed.

23_WS_OM_EN_USC_t.book Page 246

SAFETY247
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. TSC will become
active automatically once an excessively swaying trailer is
recognized.
NOTE:TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 178.
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)
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.
The BSM detection zone covers approximately one lane in
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the side of the vehicle, near the B-pillar,
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 is 7 mph (11 km/h) or higher and will alert
the driver of vehicles in these areas. BSM will alert earlier
on faster-approaching vehicles – up to 33 mph (54 km/h)
difference.
NOTE: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 random false detections
on the trailer, and false chimes when the turn signal is
used
Úpage 197.
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a “Blind Spot Temporarily Unavailable, Sensor Blocked”
message will display in the cluster, both mirror lights will
illuminate, and BSM and RCP alerts will not occur. This is
normal operation. The system will automatically recover
and resume function when the condition clears or when
an ignition cycle occurs. To minimize system blockage, do
not block the area of the rear fascia/ bumper where the
radar sensors are located with foreign objects (bumper
stickers, bicycle racks, etc.) and keep it clear of road
contaminations.

Sensor Location (Left Side Shown)

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_WS_OM_EN_USC_t.book Page 247

248SAFETY
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, when the turn
signal is activated during the alert on the side of the
vehicle corresponding to the alert, an audible (chime) alert
can be heard. During this audible (chime) alert, the radio
volume will be reduced
Úpage 249.

BSM Warning Light

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 33 mph (54 km/h). Fast approaching
vehicles will receive an earlier alert based on relative
speed.

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly with a relative speed of
less than 13 mph (24 km/h) the warning light will be
illuminated. If the difference in speed between the two
vehicles is greater than 13 mph (24 km/h), the warning light will not illuminate.

Overtaking/Approaching
Overtaking/Passing

23_WS_OM_EN_USC_t.book Page 248

SAFETY249
The BSM system is designed not to issue an alert on
stationary objects such as guardrails, posts, walls, foliage,
berms, 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.

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 5 mph
(8 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
obscured 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. When RCP is on and the vehicle is in REVERSE, 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 Úpage 197.
Blind Spot Alert Lights Only
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 (RCP) Detection 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.
6

23_WS_OM_EN_USC_t.book Page 249

250SAFETY
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.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
FCW with Mitigation system 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 suffi -
cient brake force, the system will compensate and provide
additional brake force as required.
If a Forward Collision Warning with Mitigation event begins
at a speed below 39 mph (62 km/h), the system may provide the maximum or partial braking 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 a standstill
for two seconds and then release the brakes.
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.
NOTE:
 The minimum speed for FCW activation is 3 mph
(5 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 an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
 The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low, the FCW
system will be automatically deactivated.

SAFETY253
(Continued)
For information on how to properly inflate the vehicle’s
tires, see
Úpage 349.
The TPMS will warn the driver of a low tire pressure if the
tire pressure falls below the low pressure warning
threshold for any reason, including low temperature
effects, or 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 recommended cold
tire pressure. Once the low tire pressure warning has been
illuminated, the tire pressure must be increased to the
recommended cold tire pressure in order for the TPMS
Warning Light to be turned off.
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.
The system will automatically update and the TPMS
Warning Light will extinguish once the updated tire
pressures have been received. The vehicle may need to be
driven for up to 20 minutes above 15 mph (24 km/h) to
receive this information. For example, your vehicle has a recommended cold
(parked for more than three hours) tire 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 sufficiently 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 have
been inflated to the vehicle’s recommended cold tire
pressure value.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 gauge, even
if underinflation has not reached the level to trigger illu -
mination 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.
CAUTION!
 The TPMS has been optimized for the original equip -
ment tires and wheels. TPMS pressures and warn -
ings have been established for the tire size equipped
on your vehicle. Undesirable system operation or
sensor damage may result when using replacement
equipment that is not of the same size, type, and/or
style. The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a poor
overall system performance or sensor damage.
Customers are encouraged to use Original Equip -
ment Manufacturer (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 dealership to have your sensor func -
tion 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 Tire Pressure Monitoring System
sensor.
CAUTION!

23_WS_OM_EN_USC_t.book Page 253

254SAFETY
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.

Tire Pressure Monitoring System Display

NOTE:It is particularly important for you to regularly check the
tire pressure in all of your tires and to maintain the proper
pressure.
The Tire Pressure Monitoring System (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, and a graphic
displaying tire pressures
 TPMS Warning Light
Tire Pressure Monitoring System Low
Pressure Warnings
The TPMS Warning Light will illuminate in the
instrument cluster, and an audible chime will
be activated, when one or more of the four
active road tire pressures are low. In addition,
the instrument cluster will display an "Inflate to XX"
message and a graphic display of the pressure value(s)
with the low tire(s) in a different color
Úpage 99.
NOTE:Your system can be set to display pressure units in
PSI, BAR, or kPa.

Low Tire Pressure Monitoring System Display

Should a low tire condition occur on any of the four active
road tire(s), you should stop as soon as possible, and
inflate the low tire(s) that is in a different color on the
graphic display to the vehicle’s recommended cold tire
pressure displayed in the “Inflate to XX” message.
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.
The system will automatically update, the graphic display
of the pressure value(s) will return to its original color and
the TPMS Warning Light will extinguish once the updated
tire pressure(s) have been received. The vehicle may need
to be driven for up to 20 minutes above 15 mph (24 km/h) to receive this information.
Service TPMS Warning
The Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds, and remain on solid when
a system fault is detected. The system fault will also sound
a chime. The instrument cluster display will display a
“SERVICE TPM SYSTEM” message for a minimum of five
seconds. This message is then followed by a graphic
display, with “--“ in place of the pressure value(s),
indicating which Tire Pressure Monitoring System
sensor(s) is not being received.
If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System
Warning Light will no longer flash, the "SERVICE TPM
SYSTEM" message will not be present, and a pressure
value will be displayed instead of dashes. A system fault
can occur by any of the following:
 Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPMS sensors.
