that the anti-lock portion of the brake system is not
functioning and that service is required. See your autho-
rized dealer immediately. The ABS light could also
illuminate during loss of traction and remain illuminated
until the brake pedal is pressed.
20. Cargo Light
The Cargo Lamp light will illuminate when the Cargo
Lamp is activated by pressing the Cargo Light Button on
the headlight switch.
21. Electronic Throttle Control (ETC)
This light informs you of a problem with the
Electronic Throttle Control system. If a prob-
lem is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experiencereduced performance, an elevated/rough idle or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on for 15 seconds as a bulb check. If the light does not
come on during starting, have the system checked by an
authorized dealer.
22. SERV 4WD Indicator
The 4WD indicator will be illuminated whenever the
4WD mode is engaged for either the manual or electric
shift 4WD systems. The SERV 4WD indicator monitors
the electric shift 4WD system. If the SERV 4WD light
stays on or comes on during driving, it means that the
4WD system is not functioning properly and that service
is required.
23. Front Fog Light Indicator — If Equipped
This light shows when the front fog lights are ON.

24. ESP/BAS Warning Lamp – If Equipped
The lamp indicates a problem with one or more
of the functions of ESP. The yellow “ESP/BAS
Warning Lamp” in the instrument cluster
comes on when the ignition switch is turned to
the “ON” position as a bulb check. It should go out with
the engine running. If the “ESP/BAS Warning Lamp”
comes on continuously with the engine running, a mal-
function has been detected in the ESP system. If this light
remains on after several ignition cycles, and the vehicle
has been driven several miles at speeds greater than 30
mph (48 km/h), see your authorized dealer as soon as
possible. NOTE:•TheESP/BAS Warning Lampcome
on momentarily each time the ignition switch is turned
ON.•The ESP Control System will make buzzing or
clicking sounds when it is actively operating.25. Low Washer Fluid Light
This light comes on when the washer fluid level falls
below approximately 1/4 full. The light will remain on
until fluid is added and ignition switch is cycled.
26. Electronic Stability Program (ESP) Indicator Light
— If Equipped
This lamp indicates the ESP system is active
when it is flashing or that a part, or all, of the
features of the ESP system are not able to
function when it is on solid. The yellow “ESP
Indicator Light” located in the tachometer area. The
ESP/TCS Indicator Lightstarts to flash as soon as the
tires lose traction and the ESP system becomes active. The
ESP/TCS Indicator Lightalso flashes when TCS is
active. If theESP/TCS Indicator Lightbegins to flash
during acceleration, ease up on the accelerator and apply
as little throttle as possible. Be sure to adapt your speed
and driving to the prevailing road conditions. The “ESP/

Electronically Shifted Transfer Case Operating
Information/Precautions (5 Position Switch)—If
Equipped
This is an electric shift transfer case and is operated by
the 4WD Control Switch (Transfer Case Switch), which is
located on the instrument panel.This Electronically Shifted transfer case provides 5 mode
positions: 2 wheel drive (2WD), 4WD AUTO, 4WD HI,
Neutral and 4WD Lo.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) or 4 wheel
drive position (4WD AUTO) for normal street and high-
way conditions (dry hard surfaced roads). Driving the
vehicle in 2WD will have greater fuel economy benefits,
as the front axle is not engaged in 2WD.
For variable driving conditions the 4WD AUTO mode
can be used. In this mode the front axle is engaged, but
the vehicle’s power is sent to the rear wheels. Four wheel
drive will be automatically engaged when the vehicle
senses a loss of traction. Because the front axle is en-
gaged, this mode will result in lower fuel economy than
the 2WD mode.

When additional traction is required, the transfer case
4WD HI and 4WD LO positions can be used to lock the
front and rear driveshafts together and force the front
and rear wheels to rotate at the same speed. This is
accomplished by rotating the 4WD Control Switch to the
desired position - see Shifting Procedure section for
specific shifting instructions. The 4WD HI and 4WD LO
positions are designed for loose, slippery road surfaces
only. Driving in the 4WD HI and 4WD LO positions on
dry hard surfaced roads may cause increased tire wear
and damage to the driveline components.

high range, 4 wheel drive low range, and neutral.
The Electronically Shifted transfer case is designed to be
driven in the 2 wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4HI and 4LO positions can be used to lock the front and
rear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the 4WD Control Switch to the desired
position - see Shifting Procedure section for specific

light will continue to flash until all the requirements for
the selected position have been met. To retry a shift:
return the control knob back to the original position,
make certain all shift requirements have been met, wait
five (5) seconds and try the shift again.
NOTE:If all the requirements to select a new transfer
case position have been met, the current position indica-
tor light will turn OFF, the selected position indicator
light will flash until the transfer case completes the shift.
When the shift is complete, the indicator light for the
selected position will stop flashing and remain ON.
2WD⇔4HI
Rotate the 4WD Control Switch to the desired position.
Shifts between 2WD and 4HI can be done with the
vehicle stopped or in motion. With the vehicle in motion,
the transfer case will engage / disengage faster if youmomentarily release the accelerator pedal after turning
the control switch. If the vehicle is stopped, the ignition
key must be in the ON position with the engine either
RUNNING or OFF. This shift cannot be completed if the
key is in the accessory position.
NOTE:The 4x4 system will not allow shifts between
2WD/4HI if the front and/or rear wheels are spinning
(no traction). In this situation the selected position indi-
cator light will flash and the original position indicator
light will remain ON. At this time, reduce speed and stop
spinning the wheels to complete the shift.
2WD or 4HI⇔4LO
NOTE:When shifting into or out of 4LO some gear
noise may be heard. This noise is normal and is not
detrimental to the vehicle or occupants.

LIMITED-SLIP DIFFERENTIAL — IF EQUIPPED
The limited-slip differential provides additional traction
on snow, ice, mud, sand and gravel, particularly when
there is a difference between the traction characteristics
of the surface under the right and left rear wheels. During
normal driving and cornering, the limited-slip unit per-
forms similarly to a conventional differential. On slip-
pery surfaces, however, the differential delivers more of
the driving effort to the rear wheel having the better
traction.
The limited-slip differential is especially helpful during
slippery driving conditions. With both rear wheels on a
slippery surface, a slight application of the accelerator
will supply maximum traction. When starting with onlyone rear wheel on an excessively slippery surface, slight
momentary application of the parking brake may be
necessary to gain maximum traction.WARNING!
On vehicles equipped with a limited-slip differen-
tial, never run the engine with one rear wheel off the
ground, since the vehicle may drive through the rear
wheel remaining on the ground. You could lose
control of the vehicle.
Care should be taken to avoid sudden accelerations when
both rear wheels are on a slippery surface. This could
cause both rear wheels to spin, and allow the vehicle to
slide sideways on the crowned surface of a road or in a
turn.
336 STARTING AND OPERATING

WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolong operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and should be avoided when
possible. Damage to the power steering pump may
occur.
ELECTRONIC BRAKE CONTROL SYSTEM
(ABS/TCS/BAS/HSA/ERM/ESP) – IF EQUIPPED
Your vehicle may be equipped with an optional ad-
vanced electronic brake control system that includes ABS
(Anti-Lock Brake System), TCS (Traction Control Sys-
tem), BAS (Brake Assist System), Hill Start Assist (HSA),
ERM (Electronic Roll Mitigation) and ESP (Electronic
Stability Program). All systems work together to enhance
vehicle stability and control in various driving conditions
and are commonly referred to as ESP.
ABS (Anti-Lock Brake System)
This system aids the driver in maintaining vehicle control
under adverse braking conditions. The system controls
hydraulic brake pressure to prevent wheel lock-up and
help avoid skidding on slippery surfaces during braking.
Refer to “Anti-Lock Brake System” in Section 5 of this
manual for more information about ABS.
