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

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, touch and release the “Sound Only”
or “Sounds and Display” button. Then touch the back
arrow soft-key. Refer to “ParkSense®” in “Understanding
The Features Of Your Vehicle” for system function and
operating information.

To disengage Paddle Shift mode, press and hold the (+)
shift paddle untilDorS is once again displayed in the
instrument cluster. You can shift in or out of Paddle Shift
mode at any time without taking your foot off the
accelerator pedal.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their
grip and the vehicle could skid, causing a collision or
personal injury.
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 Oper-
ating” 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

Shift Positions
For additional information on the appropriate use of each
4WD system mode position, see the information below:
4WD AUTO
This range is used on surfaces such as ice, snow, gravel,
sand, and dry hard pavement.
NOTE:Refer to “Selec-Terrain® – If Equipped” in “Start-
ing and Operating” for further information on the vari-
ous positions and their intended usages.
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 transmission is in PARK. 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).

STARTING AND OPERATING 415

•The ignition switch 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 switch 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” position indicator light indicates that
shift requirements have not been met.
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 func-
tions 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 system.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.

STARTING AND OPERATING 421

•Completely inspect the underbody of your vehicle.
Check tires, body structure, steering, suspension, and
exhaust system for damage.
• 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.

CAUTION!
The Anti-Lock Brake System is subject to possible
detrimental effects of electronic interference caused
by improperly installed aftermarket radios or tele-
phones.
NOTE: During severe braking conditions, a pulsing sen-
sation may occur and a clicking noise will be heard. This
is normal, indicating that the Anti-Lock Brake System is
functioning.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake
pressure is applied to the slipping wheel(s) and engine
power is reduced to provide enhanced acceleration and
stability. A feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited-slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if
ESC system is in the “Partial Off” mode. Refer to “Elec-
tronic Stability Control (ESC)” in this section for further
information.
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s braking
capability during emergency braking maneuvers. The
system detects an emergency braking situation by sens-
ing the rate and amount of brake application and then
applies optimum pressure to the brakes. This can help
reduce braking distances. The BAS complements the
anti-lock brake system (ABS). Applying the brakes very

•The cluster icon and switch lamp will flash for several
seconds then extinguish when the driver presses the
HDC switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several
seconds then extinguish when HDC deactivates due to
excess speed.
• The cluster icon and switch lamp will flash when HDC
deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.
WARNING!
HDC is only intended to assist the driver in control-
ling vehicle speed when descending hills. The driver
must remain attentive to the driving conditions and
is responsible for maintaining a safe vehicle speed.
Select Speed Control (SSC) — If Equipped
(Four-Wheel Drive Models With MP3023
Two-Speed Transfer Case Only)
SSC is intended for off road driving in 4WD Low Range
only. SSC maintains vehicle speed by actively controlling
engine torque and brakes.
