ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM

Your vehicle is equipped with an advanced Electronic
Brake Control (EBC) system. This system includes
Electronic Brake Force Distribution (EBD), Anti-Lock
Brake System (ABS), Brake Assist System (BAS), Hill
Start Assist (HSA), Traction Control System (TCS),
Electronic Stability Control (ESC), and Electronic Roll
Mitigation (ERM). These systems work together to
enhance both vehicle stability and control in various
driving conditions.

Your vehicle may also be equipped with Ready
Alert Braking (RAB) and Rain Brake Support (RBS).
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
and may stay on for as long as four seconds.
If the Brake System Warning Light remains on
or comes on while driving, it indicates that the
brake system is not functioning properly and that
immediate service is required. If the Brake System
Warning Light does not come on when the ignition
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance.
To receive the benefit of the system, you must
apply continuous braking pressure during the
stopping sequence (do not “pump” the brakes).
Do not reduce brake pedal pressure unless
braking is no longer desired. Once the brake
pedal is released, the BAS is deactivated.
Electronic Brake Force Distribution (EBD)
EBD manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, striking
objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). See Ú page 182 for a
complete explanation of the available ESC modes.
WARNING!

The Brake Assist System (BAS) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. BAS cannot prevent collisions,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or
hydroplaning. The capabilities of a BAS-equipped
vehicle must never be exploited in a reckless or
dangerous manner, which could jeopardize the
user's safety or the safety of others.

(Continued)
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 counteract the above
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 above conditions.
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.
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 roll overs, 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 conditions. Only a safe,
attentive, and skillful driver can prevent acci
-
dents. 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 characteristics 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 perfor -
mance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any
vehicle modification or poor vehicle mainte -
nance that reduces the effectiveness of the
ESC system can increase the risk of loss of
vehicle control, vehicle rollover, personal
injury and death.
WARNING!

SAFETY183
"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:
For vehicles with multiple partial ESC modes,
the push and release of the button will toggle
the ESC modes. Multiple attempts may be
required to return to "ESC On" mode.
Trailer Sway Control (TSC) is disabled when the
ESC system is in the “Partial Off” mode.
If Equipped — "ESC Sport" and "ESC Track" are
ESC “Partial Off” mode(s). “Full Off” – If Equipped

This mode is intended for off-highway or off-road use
only and should not be used on any public roadways.
In this mode, TCS and ESC features are turned off.
To enter the “Full Off” mode, push and hold the ESC
OFF button for five seconds while the vehicle is stopped
with the engine running. After five seconds, a chime will
sound, the ESC OFF Indicator Light will illuminate, and
the ESC OFF message will display in the instrument
cluster. To turn ESC on again, momentarily push the
ESC OFF button.

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
(located in the instrument cluster) 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.
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
Traction Control System (TCS) is disabled, and the
enhanced vehicle stability offered by the ESC system
is reduced.
WARNING!
In the ESC “Full Off” mode, the engine torque
reduction and stability features are disabled.
Therefore, enhanced vehicle stability offered
by the ESC system is unavailable. In an emer -
gency evasive maneuver, the ESC system will
not engage to assist in maintaining stability.
ESC “Full Off” mode is intended for
off-highway or off-road use only.
The 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 condi -
tions. ESC cannot prevent all accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent collisions.

184SAFETY
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 mode.
Each time the ignition is placed in the ON mode,
the ESC system will be on even if it was turned
off previously.
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 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 gear).
HSA will work in REVERSE gear and all forward
gears. The system will not activate if the trans -
mission is in PARK or NEUTRAL. For vehicles
equipped with a manual transmission, if the
clutch is pressed, HSA will remain active.
Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
To disable HSA, see Ú page 125 for further
information.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
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 accel -
eration, 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
collision or serious personal injury.

21_LD_OM_EN_USC_t.book Page 184

SAFETY185
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.

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 TCS and ESC are in
reduced modes.

AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BS M) —
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 or REVERSE.
BSM Warning Light
The BSM detection zone covers approximately one
lane width on both sides of the vehicle 12 ft (3.8 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. There -
fore, 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.,
6

21_LD_OM_EN_USC_t.book Page 185

186SAFETY
bicycle, sports equipment) extends beyond the
side of your vehicle, this may result in the BSM
warning light remaining illuminated the entire
time the vehicle is in a forward gear.
The Blind Spot Monitoring (BSM) system may
experience drop outs (blinking on and off) of the
side mirror Warning Indicator lamps 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
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 188 for further information.
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 31 mph (50 km/h).

Rear Monitoring

Overtaking Traffic
If you pass another vehicle slowly (with a relative
speed of 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.

21_LD_OM_EN_USC_t.book Page 186

188SAFETY
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.

Blind Spot Modes
Blind Spot Alert Lights Only

Blind Spot has three selectable modes of operation
that are available in the Uconnect system.
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 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 volume is reduced
so that the alert can be better heard.
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
audio alerts will be issued. In addition to the audible
alert the radio (if on) volume will be reduced so that the
alert can be better heard.

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 volume is reduced so
that the alert can be better heard.
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 OPERATION
FCW with Mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply haptic
warning in the form of a 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 Stability
Control (ESC) system, 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
Forward Collision Warning with Mitigation event
begins at a speed below 20 mph (32 km/h), the
system may provide the maximum or partial
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.

21_LD_OM_EN_USC_t.book Page 188

190SAFETY
FCW disables in the same manner as ACC, and
will display a screen indicating that the feature
is unavailable when it has been disabled.
FCW Limited Warning

If the instrument cluster display reads “ACC/FCW
Limited Functionality” or “ACC/FCW Limited
Functionality Clean Front Windshield” momentarily,
there may be a condition that limits FCW functionality.
Although the vehicle is still drivable under normal
conditions, the active braking may not be fully
available. Once the condition that limited the system
performance is no longer present, the system will
return to its full performance state. If the problem
persists, see an authorized dealer.

Service FCW Warning
If the system turns off, and the instrument cluster
display reads:
ACC/FCW Unavailable Service Required
Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault.
Although the vehicle is still drivable under normal
conditions, have the system checked by an
authorized dealer.
TIRE PRESSURE MONITORING
S
YSTEM (TPMS)
The Tire Pressure Monitoring System (TPMS) will
warn the driver of a low tire pressure based on the
vehicle recommended cold placard pressure.
The tire pressure will vary with temperature
by about 1 psi (7 kPa) for every 12°F (6.5°C).
This means that when the outside temperature
decreases, the tire pressure will decrease. Tire
pressure should always be set based on cold
inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for
at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire
inflation pressure must not exceed the maximum
inflation pressure molded into the tire sidewall.
The tire pressure will also increase as the vehicle
is driven — this is normal and there should be no
adjustment for this increased pressure.
See Ú page 275 for information on how to
properly inflate the vehicle’s tires.
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.
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.

For example, your vehicle may have a recommended
cold (parked for more than three hours) placard
pressure of 30 psi (207 kPa). If the ambient
temperature is 68°F (20°C) and the measured tire
pressure is 27 psi (186 kPa), a temperature drop to
20°F (-7°C) will decrease the tire pressure to
approximately 23 psi (158 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 27 psi (186 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.

21_LD_OM_EN_USC_t.book Page 190

SAFETY191
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. Underinflation also reduces fuel effi -
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate 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
pressure, and the TPMS will monitor the actual
tire pressure in the tire Ú page 305.
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.
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
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
(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
shown in a different color.
CAUTION!
The TPMS has been optimized for the original
equipment 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 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
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 your authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.

Tire Pressure Monitoring System Display

Should this occur, you should stop as soon as
possible and inflate the tires with a low pressure
condition (those shown in a different color in the
instrument cluster graphic) to the vehicle’s
recommended cold placard pressure inflation
value as shown in the “Inflate to XX” message.
Once the system receives the updated tire
pressures, the system will automatically update,
the graphic display in the instrument cluster will
change color back to the original color, and the
TPMS Warning Light will turn off. 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.
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.

Low Tire Pressure Monitoring System Display

Service Tire Pressure System Warning
If 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 Tire Pressure 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 switch 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 Tire
Pressure 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:
Signal interference due to electronic devices or
driving next to facilities emitting the same radio
frequencies as the TPMS sensors.
Accumulation of snow or ice around the wheels
or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
Vehicles With Compact Spare

1. The compact spare tire or non-matching full size does not have a Tire Pressure Monitoring
System sensor. Therefore, the TPMS will not
monitor the pressure in the compact or
non-matching full size spare tire.

2. If you install the compact or non-matching full size spare tire in place of a road tire that has a
pressure below the low-pressure warning limit,
upon the next ignition key 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 and an "Inflate to XX" message.
