ELECTRONIC BRAKE CONTROL SYSTEM -
ABS/TCS/BAS/ESP
Your vehicle is equipped with the advanced electronic
brake control system that includes Anti-Lock Brake Sys-
tem (ABS), Traction Control System (TCS) Brake Assist
System (BAS), and Electronic Stability Program (ESP). All
four systems work together to enhance vehicle stability
and control in various driving conditions, and are com-
monly referred to as ESP.
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 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 thebrake of the spinning wheel. This will allow more engine
torque to be applied to the wheel that is not spinning.
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
quickly results in the best BAS assistance. To receive the
benefit of the system, you must apply continuous brak-
ing pressure during the stopping sequence. Do not
reduce brake pedal pressure unless braking is no longer
desired. Once the brake pedal is released, the BAS is
deactivated.

raised, and the ªESP/TCS Indicator Lightº will be illu-
minated. This mode is intended to be used for a more
spirited driving experience, or if the vehicle is in deep
snow, sand, or gravel conditions and more wheel spin
that ESP would normally allow is required.
To turn ESP on again, momentarily depress the
ªESP OFFº button.
WARNING!
In the Partial ESP mode, the engine torque reduction
and stability features are desensitized. Therefore, the
enhanced vehicle stability offered by ESP is
unavailable.
NOTE:To improve the vehicle's traction when driving
with snow chains, or starting off in deep snow, sand or
gravel, it may be desirable to switch to the ªPartial ESPº
mode by pressing the ªESP OFFº button. Once thesituation requiring ESP to be switched to the ªPartial
ESPº mode is overcome, turn ESP back on by momen-
tarily depressing the ªESP OFFº button. This may be
done while the vehicle is in motion.
ESP/BAS Warning Light and ESP/TCS Indicator
Light
The malfunction indicator for the ESP is combined with
the BAS indicator. The yellow ªESP/BAS Warning
Lampº and the yellow ªESP/TCS Indicator Lightº in the
instrument cluster both come on when the ignition
switch is turned to the ªONº position. They should both
go out with the engine running. If the ªESP/BAS Warn-
ing Lampº comes on continuously with the engine
running, a malfunction has been detected in either the
ESP or BAS system, or both. 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 to have the
problem diagnosed and corrected.
158 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
It is dangerous to shift the selector lever out of ªPº or
ªNº if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the vehicle
could accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit someone or
something. Only shift into gear when the engine is
idling normally and when your right foot is firmly on
the brake pedal.
ALL WHEEL DRIVE Ð IF EQUIPPED
This feature provides full time, on-demand, All Wheel
Drive (AWD). The system is automatic with no driver
inputs or additional driving skills required. Under nor-
mal driving conditions, the front wheels provide most of
the traction. If the front wheels begin to lose traction,power is shifted automatically to the rear wheels. The
greater the front wheel traction loss, the greater the
power transfer to the rear wheels.
Additionally, on dry pavement under heavy throttle
input (where one may have no wheel spin), torque will be
sent to the rear in a preemptive effort to improve vehicle
launch and performance characteristics.
CAUTION!
All wheels must have the same size and type tires.
Unequal tire sizes must not be used. Unequal tire
size may cause failure of the power transfer unit.
284 STARTING AND OPERATING

lug nuts until each nut has been tightened twice. Correct
wheel nut tightness is 130 N´m (95 ft. lbs). If in doubt
about the correct tightness, have them checked with a
torque wrench by your dealer or at a service station.
11. Lower the jack to its fully closed position.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
NOTE:The full size flat tire will not store under the
vehicle. It should be repaired /or replaced, and rein-
stalled on the vehicle as soon as possible.
12. Secure the spare tire as follows:
²Turn the wheel so that the valve-stem is down. Slide
the wheel retainer through the center of the wheel
and position it properly across the wheel opening.
²For convenience in checking the spare tire inflation,
stow with the valve-stem toward the rear of the
vehicle.
²Using the jack-handle, rotate the drive nut to the
right until the wheel is drawn into place against the
underside of the vehicle.
²Continue to rotate the nut until you hear the mecha-
nism click three times. It cannot be overtightened.
Push against the tire several times to be sure it is
securely in place.
13. Stow the jack and jack handle.
14. Check the tire pressure as soon as possible. Correct
pressure as required.

NOTE:When reinstalling the wheel center cap, insure
that the valve stem symbol on the back of the cap is
pointed toward the wheel valve stem. Install the center
cap using hand pressure only. Do not use a hammer.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation, and after each time a tire is changed, to
allow the wheel nuts to become properly set. All nuts
should first be firmly seated against the wheel. The nuts
should then be tightened to recommended torque.
Tighten the nuts to final torque in increments. Progress
around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is
achieved. Recommended torque is 130 N´m (95 ft. lbs).
JUMP-STARTING PROCEDURE
WARNING!
²Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot
be started this way. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has a
discharged battery, booster cables may be used to obtain a
start from another vehicle. This type of start can be danger-
ous if done improperly, so follow this procedure carefully.
²Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don't lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
²A battery generates hydrogen gas which is flammable and
explosive. Keep flame or spark away from the vent holes.
Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
²Take care to avoid the radiator cooling fan whenever the
hood is raised. It can start anytime the ignition switch is on.
You can be hurt by the fan.
