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.

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.

STARTING AND OPERATING185
INFLATION PRESSURE
This is the cold tire inflation pressure for your
vehicle for all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total
weight of the vehicle with all fluids, including
vehicle fuel, at full capacity conditions, and with no
occupants or cargo loaded into the vehicle. The
front and rear curb weight values are determined
by weighing your vehicle on a commercial scale
before any occupants or cargo are added.
LOADING
The actual total weight and the weight of the front
and rear of your vehicle at the ground can best be
determined by weighing it when it is loaded and
ready for operation.
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR has not
been exceeded. The weight on the front and rear of
the vehicle should then be determined separately
to be sure that the load is properly distributed over
the front and rear axle. Weighing the vehicle may
show that the GAWR of either the front or rear axles
has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from
front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the heavier items down low and be sure that the
weight is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú
page 184.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition.
The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
WARNING!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Overloading can
shorten the life of your vehicle.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg)
or more, it is recommended to use a
weight-distributing hitch to ensure stable
handling of your vehicle. If you use a standard
weight-carrying hitch, you could lose control of
your vehicle and cause a collision.

TOWING REQUIREMENTS
To promote proper break-in of the new vehicle
drivetrain components, the following guidelines
are recommended.
Perform the maintenance listed in the Scheduled
Servicing Ú
page 330. When towing a trailer,
never exceed the GAWR or GCWR ratings.
Towing Requirements — Tires
Do not attempt to tow a trailer while using a
compact spare tire.
Do not drive more than 50 mph (80 km/h) when
towing while using a full size spare tire.
Proper tire inflation pressures are essential to
the safe and satisfactory operation of your
vehicle.
Check the trailer tires for proper tire inflation
pressures before trailer usage.
Check for signs of tire wear or visible tire
damage before towing a trailer.
Replacing tires with a higher load carrying
capacity will not increase the vehicle's GVWR
and GAWR limits.
For further information Ú page 374.
CAUTION!
Do not tow a trailer at all during the first
500 miles (805 km) the new vehicle is driven.
The engine, axle or other parts could be
damaged.
Then, during the first 500 miles (805 km) that
a trailer is towed, do not drive over 50 mph
(80 km/h) and do not make starts at full
throttle. This helps the engine and other parts
of the vehicle wear in at the heavier loads.
WARNING!
Make certain that the load is secured in the
trailer and will not shift during travel. When
trailering cargo that is not fully secured,
dynamic load shifts can occur that may be
difficult for the driver to control. You could lose
control of your vehicle and have a collision.

When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or
damage to brakes, axle, engine, transmission,
steering, suspension, chassis structure or tires.

Safety chains must always be used between
your vehicle and trailer. Always connect the
chains to the hook retainers of the vehicle
hitch. Cross the chains under the trailer
tongue and allow enough slack for turning
corners.
Vehicles with trailers should not be parked on
a grade. When parking, apply the parking
brake on the tow vehicle. Put the tow vehicle
transmission in PARK (P). For four-wheel drive
vehicles, make sure the transfer case is not in
NEUTRAL (N). Always, block or "chock" the
trailer wheels.
GCWR must not be exceeded.
Total weight must be distributed between the
tow vehicle and the trailer such that the
following four ratings are not exceeded :
GVWR
GTW
WARNING!
GAWR
Tongue weight rating for the trailer hitch
utilized
WARNING!

23_WL_OM_EN_USC_t.book Page 192

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.

268SAFETY
Beginning with the next ignition cycle, the TPMS
will no longer chime or display the “SERVICE TPM
SYSTEM” message in the instrument cluster but
dashes (--) will remain in place of the pressure
values.
To reactivate the TPMS, replace all four wheel and
tire assemblies (road tires) with tires equipped with
TPMS sensors. Then, drive the vehicle for up to
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 turn off. The
instrument cluster will display the “SERVICE TPM
SYSTEM” message and then display pressure
values in place of the dashes. On the next ignition
cycle the "SERVICE TPM SYSTEM" message will no
longer be displayed as long as no system fault
exists.
Tire Fill Alert
This feature notifies the user when the placard tire
pressure is attained while inflating or deflating the
tire.
The customer may choose to disable or enable the
Tire Fill Alert feature in the apps menu of the
Uconnect system.
NOTE:
The Tire Fill Alert system will only support
inflating or deflating one tire at a time. The user
is required to wait until the hazard lights STOP flashing or 26-30 seconds after the desired
pressure is achieved in one wheel before
switching to another.
The Tire Fill Alert feature cannot be entered if an
existing TPMS fault is set to “active” or if the
system is in deactivation mode (if equipped).
The system will be activated when the system
detects an increase in tire pressure while filling the
tire. The ignition must be in the ON/RUN mode with
the transmission in PARK for vehicles equipped
with an automatic transmission. For vehicles
equipped with a manual transmission, the parking
brake must be applied.
NOTE:It is not required to have the engine running to
enter Tire Fill Alert mode.
The hazard lamps will come on to confirm the
vehicle is in Tire Fill Alert mode. If the hazard lamps
do not come on while inflating the tire, the Tire
Pressure Monitoring System sensor may be in an
inoperative position, preventing the TPMS sensor
signal from being received. In this case, the vehicle
may need to be moved slightly forward or
backward.
When Tire Fill Alert mode is entered, the tire
pressure display screen will be displayed in the
instrument cluster. Operation:
The horn will chirp once to let the user know
when to stop filling the tire, when it reaches
recommended pressure.
The horn will chirp three times if the tire is over
-
filled and will continue to chirp every five
seconds if the user continues to inflate the tire.
The horn will chirp once again when enough air
is let out to reach proper inflation level.
The horn will also chirp three times if the tire is
then underinflated and will continue to chirp
every five seconds if the user continues to
deflate the tire.
Selectable Tire Fill Alert (STFA) —
If Equipped
The Selectable Tire Fill Alert (STFA) system is an
optional feature that is included as part of the
normal Tire Fill Alert system. The system is
designed to allow you to select a pressure to inflate
or deflate the vehicle's front and rear axle tires to,
and to provide feedback while inflating or deflating
the vehicle's tires.
