Night Vision Animal Warning Light
The Night Vision Animal Warning Light
will illuminate in yellow when an animal is
approaching or is in the vehicle’s path
Úpage 177.
Night Vision Pedestrian Warning Light
The Night Vision Pedestrian Warning
Light will illuminate in yellow when a
pedestrian is approaching or is in the
vehicle’s path Ú page 177.
Service 4WD Warning Light — If Equipped
This warning light will illuminate to signal
a fault with the 4WD system. If the light
stays on or comes on during driving, it
means that the 4WD system is not
functioning properly and that service is required.
We recommend you drive to the nearest service
center and have the vehicle serviced immediately.
Service Adaptive Cruise Control (ACC)
Warning Light
This light will turn on when the ACC is not
operating and needs service
Ú page 142.
Service Forward Collision Warning (FCW)
Or Pedestrian Emergency Braking (PEB)
Warning Light — If Equipped
This warning light will illuminate to
indicate a fault in the FCW or PEB
System. Contact an authorized dealer for
service Ú page 261.
Service Stop/Start System Warning Light —
If Equipped
This warning light will illuminate when the
Stop/Start system is not functioning
properly and service is required. Contact
an authorized dealer for service.
Sway Bar Fault Warning Light
This light will illuminate when there is a
fault in the sway bar disconnect system
Úpage 133.
Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a
message is displayed to indicate that the
tire pressure is lower than the
recommended value and/or that slow
pressure loss is occurring. In these cases, optimal
tire duration and fuel consumption may not be
guaranteed. Should one or more tires be in the condition
previously mentioned, the display will show the
indications corresponding to each tire.
Each tire, including the spare (if provided), should
be checked monthly when cold and inflated to the
inflation pressure recommended by the vehicle
manufacturer on the vehicle placard or tire
inflation pressure label. If your vehicle has tires of
a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has been
equipped with a TPMS that illuminates a low tire
pressure telltale when one or more of your tires is
significantly underinflated. Accordingly, when the
low tire pressure telltale illuminates, you should
stop and check your tires as soon as possible, and
inflate them to the proper pressure. Driving on a
significantly underinflated tire causes the tire to
overheat and can lead to tire failure. Underinflation
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop the
vehicle, avoiding sharp braking and steering. If a
tire puncture occurs, repair immediately using
the dedicated tire repair kit and contact an
authorized dealer as soon as possible.

also reduces fuel efficiency and tire tread life, and
may affect the vehicle’s handling and stopping
ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if underinflation has not reached the level to
trigger illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system
is not operating properly. The TPMS malfunction
indicator is combined with the low tire pressure
telltale. When the system detects a malfunction,
the telltale will flash for approximately one minute
and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists. When
the malfunction indicator is illuminated, the
system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS from
functioning properly. Always check the TPMS
malfunction telltale after replacing one or more
tires or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels allow
the TPMS to continue to function properly.
YELLOW INDICATOR LIGHTS
4WD Low Indicator Light — If Equipped
This light alerts the driver that the vehicle
is in the 4WD Low mode. The front and
rear driveshafts are mechanically locked
together forcing the front and rear
wheels to rotate at the same speed. Low range
provides a greater gear reduction ratio to provide
increased torque at the wheels Ú page 131.
Air Suspension Active Indicator Light —
If Equipped
This light will illuminate when the air
suspension system is actively adjusting
the ride height Úpage 136.
Air Suspension Aerodynamic Height
Indicator Light— If Equipped
This light will illuminate when the air
suspension system is set to the
Aerodynamic setting Ú page 136.
Air Suspension Entry/Exit Indicator Light—
If Equipped
This light will illuminate when the vehicle
is automatically lowered from ride height
position downward for easy entry and exit
of the vehicle.

Air Suspension Off-Road 1 Indicator Light —
If Equipped

This light will illuminate when the air
suspension system is set to the Off-Road
1 setting Úpage 136.

Air Suspension Off-Road 2 Indicator Light —
If Equipped

This light will illuminate when the air
suspension system is set to the Off-Road
2 setting Úpage 136.
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. Aftermarket
wheels can cause sensor damage. 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.

23_WL_OM_EN_USC_t.book Page 114

264SAFETY
Turning PEB On Or Off
NOTE:The default status of PEB is “On.” This allows the
system to warn you of a possible frontal collision
with the pedestrian.
The PEB button is located in the Uconnect display
in the Control settings Ú page 204.
To turn the PEB system off, push the Pedestrian
Emergency Braking button.
To turn the PEB system back on, push the Warning
Active Braking button.
Changing the PEB status to “Off” deactivates the
system, so no warning or active braking will be
available in case of a possible frontal collision with
the pedestrian/cyclist.
NOTE:The PEB system will retain the last setting selected
by the driver after ignition shut down. The system
will not reset to the default setting when the
vehicle is restarted.
Intersection Collision Assist (ICA) —
If Equipped
ICA uses three front radar sensors located in the
front fascia/bumper, to detect oncoming vehicles
from the front or side when driving through an
intersection. When the system determines that a
collision is probable when turning across
oncoming traffic, the system will attempt to
mitigate a possible collision by decelerating the
vehicle. When the system determines that a
collision with a crossing vehicle is probable, the
system may apply additional braking to
supplement the driver braking input to attempt to
mitigate a possible collision. The system will also
provide audible warnings and visual warnings
(shown in the instrument cluster). If the driver
determines acceleration is needed to avoid a
collision, when the accelerator is pressed ICA will
cancel.
TIRE PRESSURE MONITORING SYSTEM
(TPMS)
The TPMS will warn the driver of a low tire pressure
based on the vehicle recommended cold tire
pressure Ú page 408.
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
tire pressure will also increase as the vehicle is
driven — this is normal and there should be no
adjustment for this increased pressure.

For information on how to properly inflate the
vehicle’s tires, see Ú
page 374.
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.
WARNING!
Pedestrian Emergency Braking (PEB) is not
intended to avoid a collision on its own, nor can
PEB detect every type of potential collision with
a pedestrian. The driver has the responsibility to
avoid a collision by controlling the vehicle via
braking and steering. Failure to follow this
warning could lead to serious injury or death.

23_WL_OM_EN_USC_t.book Page 264

SAFETY265
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 36 psi (248 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, unless
equipped with Tire Fill Alert.
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 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.
CAUTION!

The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warnings 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
Equipment 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 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 Tire Pres -
sure Monitoring System sensor.

266SAFETY
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 Ú page 98.
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 system will automatically
update the graphic display of the pressure value(s)
and will return to its original color. The TPMS
Warning Light will extinguish once the updated tire
pressure(s) have been received in the case when
the ignition is ON. In the case when the ignition is
OFF, the ignition on the vehicle has to be turned ON
and may need to be driven for up to 20 minutes
above 15 mph (24 km/h) to receive this
information for the pressure value(s) to be
updated.

23_WL_OM_EN_USC_t.book Page 266

SAFETY267
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.
Lots of snow or ice around the wheels or wheel
housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with TPMS
sensors.
NOTE:A TPMS sensor is not offered on any size spare tire.
In either option of having a full size spare equipped
or not, the tire pressure is not monitored or
displayed on the cluster for the corresponding
spare tire location. If you install the spare tire in
place of a road tire that has a pressure below the
low-pressure warning limit, upon the next ignition
switch cycle, the Tire Pressure Monitoring System
Warning Light will remain on, a chime will sound,
and the instrument cluster display will still display
a pressure value in the different color graphic
display and an “Inflate to XX” message will be
displayed. After driving the vehicle for up to
20 minutes above 15 mph (24 km/h), the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on
solid. In addition, the instrument cluster display
will display a “SERVICE TPM SYSTEM" message for
five seconds and then display dashes (--) in place
of the pressure value. For each subsequent
ignition switch cycle, a chime will sound, the Tire
Pressure Monitoring System Warning Light will
flash on and off for 75 seconds and then remain on
solid, and the instrument cluster display will
display a "SERVICE TPM SYSTEM" message for five
seconds and then display dashes (--) in place of the
pressure value. Once you repair or replace the
original road tire, and reinstall it on the vehicle in
place of the spare tire, the TPMS will update auto -
matically. In addition, the Tire Pressure Monitoring System
Warning Light will turn off and the graphic in the
instrument cluster display 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.
TPMS Deactivation — If Equipped
The Tire Pressure Monitoring System (TPMS) can
be deactivated by replacing all four wheel and tire
assemblies (road tires) with wheel and tire
assemblies that do not have TPMS sensors, such
as when installing winter wheel and tire
assemblies on your vehicle.
To deactivate the TPMS, first, replace all four wheel
and tire assemblies (road tires) with tires not
equipped with Tire Pressure Monitoring System
sensors. Then, drive the vehicle for 20 minutes
above 15 mph (24 km/h). The TPMS will chime,
the TPMS Warning Light will flash on and off for 75
seconds and then remain on. The instrument
cluster will display the “SERVICE TPM SYSTEM”
message and then display dashes (--) in place of
the pressure values.
