Vehicle Security Warning Light —
If Equipped

This light will flash at a fast rate for
approximately 15 seconds when the vehicle
security system is arming, and then will flash
slowly until the vehicle is disarmed.

YELLOW WARNING LIGHTS
Active Driving Assist - Driver
Inattentiveness Warning Light
This light illuminates when driver
inattentiveness has been detected,
warning the driver to place their hands on
the steering wheel.
Active Driving Assist Fault Warning Light
This light will turn on when the Active
Driving Assist system has detected a
fault.
Air Suspension Fault Warning Light
This light will illuminate when there is a
fault detected in the air suspension
system.

Anti-Lock Brake System (ABS) Warning Light

This warning light monitors the ABS. The
light will turn on when the ignition is
placed in the ON/RUN or position and
may stay on for as long as four seconds.
If the ABS light remains on or turns on while
driving, then the Anti-Lock portion of the brake
system is not functioning and service is required as
soon as possible. However, the conventional brake
system will continue to operate normally,
assuming the Brake Warning Light is not also on.
If the ABS light does not turn on when the ignition
is placed in the ON/RUN position, have the brake
system inspected by an authorized dealer.
Electric Park Brake Fault Warning Light
This warning light will illuminate to
indicate the Electric Park Brake is not
functioning properly and service is
required. Contact an authorized dealer.
Electronic Stability Control (ESC) Active
Warning Light — If Equipped
This warning light will indicate when the
ESC system is Active. The ESC Indicator
Light in the instrument cluster will come
on when the ignition is placed in the ON/
RUN position, and when ESC is activated. It should
go out with the engine running. If the ESC Indicator
Light comes on continuously with the engine
running, a malfunction has been detected in the
ESC system. If this warning 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 OFF Indicator Light and the ESC Indi -
cator Light come on momentarily each time the
ignition is placed in the ON/RUN position.
The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive.
This light will come on when the vehicle is in an
ESC event.
WARNING!
If you continue operating the vehicle when the
Transmission Temperature Warning Light is
illuminated you could cause the fluid to boil over,
come in contact with hot engine or exhaust
components and cause a fire.
CAUTION!
Continuous driving with the Transmission
Temperature Warning Light illuminated will
eventually cause severe transmission damage
or transmission failure.

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

STARTING AND OPERATING131
SPORT MODE — IF EQUIPPED

SPORT Mode

Your vehicle is equipped with a Sport Mode
feature. When activated, the engine and
transmission, steering and suspension (if
equipped with air suspension) are all set to their
SPORT settings. Sport Mode will provide improved
throttle response and modified transmission shift
points as well as firmer suspension and steering
for an enhanced driving experience. This mode
may be activated and deactivated by pushing the
SPORT ON button on the instrument panel switch
bank or by selecting SPORT mode using the
Selec-Terrain switch (if equipped). When Sport
Mode has been activated an indicator light will
illuminate in the instrument cluster.
FOUR-WHEEL DRIVE OPERATION
The driveline is equipped with a Front Axle
Disconnect (FAD) for the one-speed and two-speed
drivelines. The FAD operation is fully automated
and controlled by the Drivetrain Control Module
(DTCM). It does not require any customer input to
engage. The FAD is set to connect, disconnect and
provide 4WD function based on certain set
conditions detected by the DTCM, including but not
limited to the following:
Ambient temperature
Wipers
Selec-Terrain Mode selection
Wheel-slip detection
The FAD is actuated only in 4WD HI range and
stays connected for 4WD LOW.
QUADRA-TRAC I OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which enables on-demand
four-wheel drive with active torque management.
No driver interaction is required. The Brake
Traction Control (BTC) system, which combines
standard ABS and Traction Control, provides
resistance to any wheel that is slipping to allow
additional torque transfer to wheels with traction.
NOTE:The Quadra-Trac I system is not appropriate for
conditions where 4WD LOW range is recom -
mended Ú page 200.
QUADRA-TRAC II OPERATING
I
NSTRUCTIONS/PRECAUTIONS —
I
F EQUIPPED
The Quadra-Trac II system comes equipped with a
customer-selectable electronically operated
on-demand transfer case with active torque
management in all driveable ranges. This transfer
case provides the following operating range
positions:
4WD HI
N (NEUTRAL)
4WD LOW
When additional tractive effort and torque are
required, the 4WD LOW position can be used. The
4WD LOW position is intended for loose, slippery
road surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause
increased tire wear and damage to driveline
components.
When operating your vehicle in 4WD LOW, the
engine speed is approximately three times that of
the normal 4WD HI position at a given road speed.
Take care not to overspeed the engine and do not
exceed 25 mph (40 km/h).
