108GETTING TO KNOW YOUR INSTRUMENT PANEL
WARNING LIGHTS AND MESSAGES
The warning/indicator lights will illuminate in the
instrument panel together with a dedicated
message and/or acoustic signal when applicable.
These indications are indicative and precautionary
and as such must not be considered as exhaustive
and/or alternative to the information contained in
the Owner’s Manual, which you are advised to read
carefully in all cases. Always refer to the
information in this chapter in the event of a failure
indication. All active telltales will display first if
applicable. The system check menu may appear
different based upon equipment options and
current vehicle status. Some telltales are optional
and may not appear.
RED WARNING LIGHTS
Active Driving Assist - Driver
Inattentiveness Warning Light
This light illuminates when driver
inattentiveness has been continually
detected, warning the driver to place
their hands on the steering wheel.
Air Bag Warning Light
This warning light will illuminate to
indicate a fault with the air bag, and will
turn on for four to eight seconds as a bulb
check when the ignition is placed in the
ON/RUN position. This light will illuminate with a single chime when a fault with the air bag has been
detected, it will stay on until the fault is cleared. If
the light is either not on during startup, stays on, or
turns on while driving, have the system inspected
at an authorized dealer as soon as possible.
Brake Warning Light
This warning light monitors various brake
functions, including brake fluid level and
parking brake application. If the brake
light turns on it may indicate that the
parking brake is applied, that the brake fluid level
is low, or that there is a problem with the Anti-Lock
Brake System reservoir.
If the light remains on when the parking brake has
been disengaged, and the fluid level is at the full
mark on the master cylinder reservoir, it indicates
a possible brake hydraulic system malfunction or
that a problem with the Brake Booster has been
detected by the Anti-Lock Brake System (ABS) /
Electronic Stability Control (ESC) system. In this
case, the light will remain on until the condition has
been corrected. If the problem is related to the
brake booster, the ABS pump will run when
applying the brake, and a brake pedal pulsation
may be felt during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual
brake system is indicated by the Brake Warning
Light, which will turn on when the brake fluid level in the master cylinder has dropped below a
specified level.
The light will remain on until the cause is corrected.
NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level
conditions. The vehicle should have service
performed, and the brake fluid level checked.
If brake failure is indicated, immediate repair is
necessary.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake
Force Distribution (EBD). In the event of an EBD
failure, the Brake Warning Light will turn on along
with the ABS Light. Immediate repair to the ABS
system is required.
Operation of the Brake Warning Light can be
checked by turning the ignition switch from the OFF
position to the ON/RUN position. The light should
illuminate for approximately two seconds. The light
should then turn off unless the parking brake is
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have a collision. Have the vehicle checked
immediately.

GETTING TO KNOW YOUR INSTRUMENT PANEL111
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.

128STARTING AND OPERATING
Only shift from DRIVE to PARK or REVERSE when
the accelerator pedal is released and the vehicle is
stopped. Be sure to keep your foot on the brake
pedal when shifting between these gears.
The transmission gear selector has only PARK,
REVERSE, NEUTRAL, and DRIVE positions. Manual
downshifts can be made using the steering wheel
mounted paddle shifters. Pulling the -/+ switches
(on the steering wheel) while in the DRIVE position
will select the highest available transmission gear,
and will display that gear limit in the instrument
cluster as 1, 2, 3, etc. Some models will display
both the selected gear limit, and the actual current
gear, while in AutoStick mode.
Transmission Gear Selector
Gear Ranges
Do not press the accelerator pedal when shifting
from PARK (P) or NEUTRAL (N) into another gear
range.
NOTE:After selecting any gear range, wait a moment to
allow the selected gear to engage before acceler -
ating. This is especially important when the engine
is cold.
PARK (P)
This range supplements the parking brake by
locking the transmission. The engine can be
started in this range. Never attempt to use PARK
while the vehicle is in motion. Apply the parking
brake when exiting the vehicle in this range.
When parking on a hill, apply the parking brake
before shifting the transmission to PARK. As an
added precaution, turn the front wheels toward the
curb on a downhill grade and away from the curb
on an uphill grade.
When exiting the vehicle, always:
Apply the parking brake.
Shift the transmission into PARK.
Turn the ignition OFF.
Remove the key fob from the vehicle.
NOTE:On four-wheel drive vehicles be sure that the
transfer case is in a drive position. The following indicators should be used to ensure
that you have properly engaged the transmission
into the PARK position:
When shifting into PARK, rotate the shifter all
the way counterclockwise until the indicator
displays PARK.
Look at the transmission gear position display
and verify that it indicates the PARK position (P),
and is not blinking.
With the brake pedal released, verify that the
gear selector will not move out of PARK.
REVERSE (R)
This range is for moving the vehicle backward.
Shift into REVERSE only after the vehicle has come
to a complete stop.
CAUTION!
Before moving the transmission gear selector
out of PARK, you must start the engine, and
also press the brake pedal. Otherwise,
damage to the gear selector could result.
DO NOT race the engine when shifting from
PARK or NEUTRAL into another gear range, as
this can damage the drivetrain.

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).
