Yellow TelltaleLight What It Means
Service 4WD Indicator Light
If the light stays on or comes on during driving, it means that the 4WD system is not function-
ing properly and that service is required. We recommend you drive to the nearest service center
and have the vehicle serviced immediately.
4WD Low Indicator Light — If Equipped
Yellow Telltale
Light What It Means
4WD Low Indicator Light
This light alerts the driver that the vehicle is in the four-wheel drive 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.

The amount of directional torque the steering system can
apply to the steering wheel to correct for vehicle lane
departure can be set at Low, Medium or High. To make
your selection, touch the “Lane Departure Warning”
soft-key until a check-mark appears next to setting,
indicating that the setting had been selected. Touch the
back arrow soft-key to return to the previous menu.
•Rear ParkSense Chime Volume
The Rear ParkSense Chime Volume settings can be se-
lected from the DID or Uconnect System — if equipped.
The chime volume settings include LOW, MEDIUM, and
HIGH. The factory default volume setting is MEDIUM.
To make your selection, press the “ParkSense Rear Chime
Volume” button on the touchscreen, indicating that the
setting had been selected. ParkSense will retain its last
known configuration state through ignition cycles. •
Rear ParkSense Braking Assist
To make your selection, press the “Rear ParkSense Brak-
ing Assist” button on the touchscreen, indicating that the
setting had been selected.
NOTE: When this feature is selected, the ParkSense
system will detect objects located behind the vehicle and
utilize autonomous braking to help stop the vehicle (only
enabled when ParkSense is also on). Refer to “ParkSense
Rear Braking Assist” in “Understanding The Features Of
Your Vehicle” for system function and operating infor-
mation.
• Blind Spot Alert
When this feature is selected, the Blind Spot Alert feature
Provides alerts, visual and/or audible, to indicate objects
in your blind spot. The Blind Spot Alert feature can be
activated in “Lights” mode. When this mode is selected,
the Blind Spot Monitor (BSM) system is activated and

•Lane Departure Warning (LDW) Strength —
If Equipped
When this feature is selected, it sets the strength of the
steering wheel feedback for potential lane departures.
The amount of directional torque the steering system can
apply to the steering wheel to correct for vehicle lane
departure can be set at Low, Medium or High. To make
your selection, touch the “Lane Departure Warning”
soft-key until a check-mark appears next to setting,
indicating that the setting had been selected. Touch the
back arrow soft-key to return to the previous menu.
• ParkSense
The ParkSense system will scan for objects behind the
vehicle when the transmission shift lever is in REVERSE
and the vehicle speed is less than 11 mph (18 km/h). It
will provide an alert (audible and/or visual) to indicate
the proximity to other objects. The system can be enabled
with Sound Only, or Sound and Display. To change the ParkSense status, press and release the “Sound” or
“Sound and Display” button. Refer to “ParkSense” in
“Understanding The Features Of Your Vehicle” for sys-
tem function and operating information.
CAUTION!
•
ParkSense is only a parking aid and it is unable to
recognize every obstacle, including small obstacles.
Parking curbs might be temporarily detected or not
detected at all. Obstacles located above or below
the sensors will not be detected when they are in
close proximity.
• The vehicle must be driven slowly when using
ParkSense in order to be able to stop in time when
an obstacle is detected. It is recommended that the
driver looks over his/her shoulder when using
ParkSense.

FOUR-WHEEL DRIVE OPERATION
Quadra-Trac I Operating Instructions/Precautions
— If Equipped
The Quadra-Trac I is a single-speed (HI range only)
transfer case, which provides convenient full-time four-
wheel drive. 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 recommended.
Refer to “Off-Road Driving Tips” in “Starting And Op-
erating” for further information.
Quadra-Trac II Operating Instructions/Precautions
— If Equipped
The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW
This transfer case is fully automatic in the 4WD HI mode.
When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at
the same speed. 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.

STARTING AND OPERATING 479

NEUTRAL
This range disengages the driveline from the powertrain.
It is to be used for flat towing behind another vehicle.
Refer to “Recreational Towing” in “Starting And Operat-
ing” for further information.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the power transfer unit
in the NEUTRAL (N) position without first fully
engaging the parking brake. The NEUTRAL (N)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the vehicle
to roll, even if the automatic transmission is in PARK
(or manual transmission is in gear). The parking
brake should always be applied when the driver is
not in the vehicle.
4WD LOW
This range is for low speed four-wheel drive. It provides
an additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose,
slippery road surfaces only. Do not exceed 25 mph
(40 km/h).
NOTE:Refer to “Selec-Terrain – If Equipped” for further
information on the various positions and their intended
usages.
Shifting Procedures
4WDHITo4WDLOW
With the vehicle at speeds of 0 to 3 mph (0 to 5 km/h),
the ignition switch in the ON position or the engine
running, shift the transmission into “N”, and push
the “4WD LOW” button once on the transfer case switch.

STARTING AND OPERATING 481

Quadra-Drive II System — If Equipped
The optional Quadra-Drive II System features two torque
transfer couplings. The couplings include an Electronic
Limited-Slip Differential (ELSD) rear axle and the
Quadra-Trac II transfer case. The optional ELSD axle is
fully automatic and requires no driver input to operate.
Under normal driving conditions, the unit functions as a
standard axle, balancing torque evenly between left and
right wheels. With a traction difference between left and
right wheels, the coupling will sense a speed difference.
As one wheel begins to spin faster than the other, torque
will automatically transfer from the wheel that has less
traction, to the wheel that has traction. While the transfer
case and axle coupling differ in design, their operation is
similar. Follow the Quadra-Trac II transfer case shifting
information, preceding this section, for shifting this sys-
tem.
SELEC-TERRAIN — IF EQUIPPED
Description
Selec-Terrain combines the capabilities of the vehicle
control systems, along with driver input, to provide the
best performance for all terrains.

486 STARTING AND OPERATING

•Inspect the radiator for mud and debris and clean as
required.
• Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. Retighten them, if required, and torque to the
values specified in the Service Manual.
• Check for accumulations of plants or brush. These
things could be a fire hazard. They might hide damage
to fuel lines, brake hoses, axle pinion seals, and
propeller shafts.
• After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan, brake
rotors, wheels, brake linings, and axle yokes inspected
and cleaned as soon as possible.WARNING!
Abrasive material in any part of the brakes may cause
excessive wear or unpredictable braking. You might
not have full braking power when you need it to
prevent a collision. If you have been operating your
vehicle in dirty conditions, get your brakes checked
and cleaned as necessary.
• If you experience unusual vibration after driving in
mud, slush or similar conditions, check the wheels for
impacted material. Impacted material can cause a
wheel imbalance and freeing the wheels of it will
correct the situation.
