selection button is adjacent to the air suspension
switch. Shifts into and out of transfer case N
(NEUTRAL) can take place with the selector switch
in any mode position.
NOTE:
Ensure vehicle is set to Normal Ride Height - if
equipped Ú page 136.
If the vehicle is equipped with Quadra-Lift air
suspension, the engine should be started and
left running for a minimum of 60 seconds (with
all the doors closed) at least once every 24
hours. This process allows the air suspension to
adjust the vehicle’s ride height to compensate
for temperature effects.
CAUTION!
Towing with the rear wheels on the ground will
cause severe transmission damage. Damage
from improper towing is not covered under the
New Vehicle Limited Warranty.

STARTING AND OPERATING197
Shifting Into Transfer Case N (NEUTRAL)
Use the following procedure to prepare your
vehicle for recreational towing:

1. Bring the vehicle to a complete stop on level
ground, with the engine running.

2. Press and hold the brake pedal.
3. Shift the transmission into NEUTRAL. 4. If vehicle is equipped with Quadra-Lift air
suspension, ensure the vehicle is set to
Normal Ride Height with the Auto Entry/Exit
setting deselected.
NOTE:
Steps 1 through 4 are requirements that
must be met before pushing the N
(NEUTRAL) button, and must continue to be
met until the shift has been completed. If
any of these requirements are not met
before pushing the N (NEUTRAL) button or
are no longer met during the shift, then the
N (NEUTRAL) indicator light will flash contin -
uously until all requirements are met or until
the N (NEUTRAL) button is released.
The ignition must be in the ON/RUN position
for a shift to take place and for the position
indicator lights to be operable. If the ignition
is not in the ON/RUN position, the shift will
not take place and no position indicator
lights will be on or flashing.
A flashing N (NEUTRAL) position indicator
light indicates that shift requirements have
not been met.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing
with only one set of wheels on the ground
(front or rear) will cause severe transmission
and/or transfer case damage. Tow with all
four wheels either ON the ground, or OFF the
ground (using a vehicle trailer).
Tow only in a forward direction. Towing this
vehicle backwards can cause severe damage
to the transfer case.
The transmission must be in PARK for recre -
ational towing.
Before recreational towing, perform the proce -
dure outlined under “Shifting into N
(NEUTRAL)” to be certain that the transfer
case is fully in N (NEUTRAL). Otherwise,
internal damage will result.
Towing this vehicle in violation of the above
requirements can cause severe transmission
and/or transfer case damage. Damage from
improper towing is not covered under the New
Vehicle Limited Warranty.
Do not use a bumper-mounted clamp-on tow
bar on your vehicle. The bumper face bar will
be damaged.
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the N (NEUTRAL) position without first
fully engaging the Electric Park Brake. The
transfer case N (NEUTRAL) position disengages
both the front and rear driveshafts from the
powertrain and will allow the vehicle to roll, even
if the transmission is in PARK. The Electric Park
Brake should always be applied when the driver
is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be certain
that the transfer case is fully in N (NEUTRAL)
before recreational towing to prevent damage to
internal parts.

198STARTING AND OPERATING
If the vehicle is equipped with Quadra-Lift
air suspension, the engine should be
started and left running for a minimum of
60 seconds (with all the doors closed) at
least once every 24 hours. This process
allows the air suspension to adjust the
vehicle’s ride height to compensate for
temperature effects.
Engaging/disengaging of the Electric Park
Brake requires the ignition to be in the ON/
RUN position.
If shift conditions/interlocks are not met, a
“4WD Shift Canceled” or a “4WD Shift

STARTING AND OPERATING201
Standing Water
Avoid driving in standing water deeper than
24 inches (61 cm) with air suspension or
21 inches (53 cm) without air suspension, and
reduce speed appropriately to minimize wave
effects. Maximum speed is 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to 4WD LOW if necessary Ú page 131. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the transfer case to 4WD
LOW. Use FIRST gear and 4WD LOW for very steep
hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to
a stop and immediately apply the brakes. Restart
the engine, and shift into REVERSE (R). Back slowly
down the hill, allowing the compression braking of
the engine to help regulate your speed. If the
brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires. Remember, never drive diagonally across a hill.
Always drive straight up or down.
If the wheels start to slip as you approach the crest
of a hill, ease off the accelerator and maintain
forward motion by turning the front wheels slowly.
This may provide a fresh “bite” into the surface and
will usually provide traction to complete the climb.
Traction Downhill
When descending mountains or hills, use Hill
Descent Control or Selec-Speed Control to avoid
repeated heavy braking.
If not equipped with Hill Descent Control or
Selec-Speed Control use the following procedure:
Shift the transmission into a low gear, and the
transfer case into 4WD LOW range. Let the vehicle
go slowly down the hill with all four wheels turning
against engine compression drag. This will permit
you to control the vehicle speed and direction.
When descending mountains or hills, repeated
braking can cause brake fade with loss of braking
control. Avoid repeated heavy braking by
downshifting the transmission whenever possible.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle. Always
back carefully straight down a hill in REVERSE
gear. Never back down a hill in NEUTRAL using
only the brake.

SAFETY
SAFETY FEATURES
ANTI-LOCK BRAKE SYSTEM (ABS)
The ABS provides increased vehicle stability and
brake performance under most braking conditions.
The system automatically prevents wheel lock and
enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that
the ABS is working properly each time the vehicle
is started and driven. During this self-check, you
may hear a slight clicking sound as well as some
related motor noises.
The ABS is activated during braking when the
system detects one or more wheels are beginning
to lock. Road conditions such as ice, snow, gravel,
bumps, railroad tracks, loose debris, or panic stops
may increase the likelihood of ABS activation(s).
You also may experience the following normal
characteristics when the ABS activates:
ABS motor noise or clicking sounds (you may
continue to hear for a short time after the stop)
Brake pedal pulsations
A slight drop of the brake pedal at the end of the
stopThe ABS is designed to function with the Original
Equipment Manufacturer (OEM) tires. Modification
may result in degraded ABS performance.
Anti-Lock Brake System (ABS) Warning
Light
The yellow ABS 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 ABS Warning Light remains on or comes on
while driving, it indicates that the anti-lock portion
of the brake system is not functioning and that
service is required. However, the conventional
brake system will continue to operate normally if
the ABS Warning Light is on.
WARNING!
The ABS contains sophisticated electronic
equipment that may be susceptible to interfer
-
ence caused by improperly installed or high
output radio transmitting equipment. This
interference can cause possible loss of
anti-lock braking capability. Installation of
such equipment should be performed by qual -
ified professionals.
Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer.
Just press firmly on your brake pedal when you
need to slow down or stop.
The ABS cannot prevent the natural laws of
physics from acting on the vehicle, nor can it
increase braking or steering efficiency beyond
that afforded by the condition of the vehicle
brakes and tires or the traction afforded.
The ABS cannot prevent collisions, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro -
planing.
The capabilities of an ABS equipped vehicle
must never be exploited in a reckless or
dangerous manner that could jeopardize the
user’s safety or the safety of others.
WARNING!

23_WL_OM_EN_USC_t.book Page 248

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.

23_WL_OM_EN_USC_t.book Page 267

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.
