CAUTION!
If the Brake System Warning Light remains on with
the parking brake released, a brake system malfunc-
tion is indicated. Have the brake system serviced by
an authorized dealer immediately.
ANTI-LOCK BRAKE SYSTEM (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
braking conditions. The system operates with a separate
computer to modulate hydraulic pressure to prevent
wheel lock-up and help avoid skidding on slippery
surfaces.ABS is activated during braking under certain road or
stopping conditions. ABS-inducing conditions can in-
clude ice, snow, gravel, bumps, railroad tracks, loose
debris, or panic stops.
You may experience the following when the brake system
goes into anti-lock:
•
The ABS motor running (it may continue to run for a
short time after the stop)
• A clicking sound of solenoid valves
• Brake pedal pulsations
• A slight drop or fall away of the brake pedal at the end
of the stop5

WARNING!
•The Anti-Lock Brake System contains sophisti-
cated electronic equipment that may be susceptible
to interference caused by improperly installed, or
high output radio transmitting equipment. This
interference can cause possible loss of anti-lock
braking capability. Installation of such equipment
should be performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
• The Anti-Lock Brake System cannot prevent colli-
sions, including those resulting from excessive
speed in turns, following another vehicle too
closely, or hydroplaning.
(Continued)
WARNING! (Continued)
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user ’s safety or
the safety of others.
• The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded.
All vehicle wheels and tires must be the same size and
type, and tires must be properly inflated to produce
accurate signals for the computer.

Anti-Lock Brake Warning Light
The “Anti-Lock Brake Warning Light” moni-
tors the anti-lock brake system. The light will
come on when the ignition switch is turned to
the ON position and may stay on for as long as
four seconds.
If the “Anti-Lock Brake Warning Light” remains on or
comes on while driving, it indicates that the anti-lock
portion of the brake system is not functioning and that
service is required. However, the conventional brake
system will continue to operate normally if the “Brake
Warning Light” is not on. If the “Anti-Lock Brake Warning Light” is on, the brake
system should be serviced as soon as possible to restore
the benefits of anti-lock brakes. If the “Anti-Lock Brake
Warning Light” does not come on when the ignition
switch is turned to the ON position, have the bulb
repaired as soon as possible.
If both the “Brake Warning Light” and the “Anti-Lock
Brake Warning Light” remain on, the ABS and Electronic
Brake Force Distribution (EBD) systems are not function-
ing. Immediate repair to the ABS system is required.
Consult with your authorized dealer service center as
soon as possible.

ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced electronic
brake control system that includes the Traction Control
System (TCS), Brake Assist System (BAS) and Electronic
Stability Control (ESC), Trailer Sway Control (TSC), and
Hill Start Assist (HSA). These systems complement the
Anti-Lock Brake System (ABS) by optimizing the vehicle
braking capability during emergency braking maneu-
vers.
Traction Control System (TCS)
The Traction Control System (TCS) 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 en-
hanced acceleration and stability. A feature of the TCS
functions similarly 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, thesystem 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
the ESC is in the “Partial Off” mode.
The “ESC Activation/Malfunction Indicator Light” (in
the instrument cluster) will start to flash as soon as the
tires lose traction and the wheels begin to spin. This
indicates that the TCS is active. If the indicator light
flashes 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,
and do not switch off the ESC or TCS.
WARNING!
•
The TCS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase the
traction afforded.

WARNING!(Continued)
•The TCS cannot prevent collisions, including those
resulting from excessive speed in turns, or hydro-
planing.
• The capabilities of a TCS-equipped vehicle must
never be exploited in a reckless or dangerous
manner, which could jeopardize the user’s safety or
the safety of others.
Brake Assist System (BAS)
The Brake Assist System (BAS) is designed to optimize
the vehicle’s braking capability during emergency brak-
ing maneuvers. The system detects an emergency brak-
ing situation by sensing 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 ABS. Applying the brakes very quickly
results in the best BAS assistance. To receive the benefit of the system, you must apply continuous braking 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.
WARNING!
•
The BAS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
the traction afforded by prevailing road conditions.
• The BAS cannot prevent collisions, including those
resulting from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
• The capabilities of a BAS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety or
the safety of others.

NOTE:
•P (Passenger) - Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European-Metric tire sizing is based on European
design standards. Tires designed to this standard have
the tire size molded into the sidewall beginning with
the section width. The letter Pis absent from this tire
size designation. Example: 215/65R15 96H.
• LT (Light Truck) - Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
• Temporary spare tires are spares designed for tempo-
rary emergency use only. Temporary high pressure
compact spare tires have the letter “T” or “S” molded
into the sidewall preceding the size designation. Ex-
ample: T145/80D18 103M.
• High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter molded
into the sidewall. Example: 31x10.5 R15 LT.

4. Stand the tire/cover assembly upright and remove thewheel spacer by squeezing the winch retaining tabs
together. Push the retainer through the spare tire to
release it from the wheel.Preparations For Jacking
1. Park the vehicle on a firm, level surface. Avoid ice orslippery areas.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic, pull far enough off
the road to avoid being hit when operating the jack
or changing the wheel.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK.
5. Turn OFF the ignition.

flange of the vehicle body.CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated.
Rear jack locations are between a pair of down-facing
tabs on the sill flange of the vehicle side body.
