BRAKES
Your service brakes are self-adjusting. Refer to the
scheduled maintenance guide for scheduled
maintenance.
Occasional brake noise is normal and often does not
indicate a performance concern with the vehicle's
brake system. In normal operation, automotive brake
systems may emit occasional or intermittent squeal
or groan noises when the brakes are applied. Such
noises are usually heard during the first few brake
applications in the morning; however, they may be
heard at any time while braking and can be
aggravated by environmental conditions such as
cold, heat, moisture, road dust, salt or mud. If a
ªmetal-to-metal,º ªcontinuous grindingº or
ªcontinuous squealº sound is present while braking,
the brake linings may be worn-out and should be
inspected by a qualified service technician.
Anti-lock brake system (ABS) (if equipped)
On vehicles equipped with an anti-lock braking
system (ABS), a noise from the hydraulic pump
motor and pulsation in the pedal may be observed
during ABS braking events. Pedal pulsation coupled
with noise while braking under panic conditions or
on loose gravel, bumps, wet or snowy roads is
normal and indicates proper functioning of the
vehicle's anti-lock brake system. The ABS performs a
self-check at 17 km/h (10 mph) after you start the
engine and begin to drive away. A brief mechanical
noise may be heard during this test. This is normal.
If a malfunction is found, the ABS warning light will
come on. If the vehicle has continuous vibration or
shudder in the steering wheel while braking, the
vehicle should be inspected by a qualified service
technician.

The ABS operates by
detecting the onset of
wheel lockup during
brake applications
and compensating for
this tendency. The
wheels are prevented
from locking even
when the brakes are firmly applied. The
accompanying illustration depicts the advantage of
an ABS equipped vehicle (on bottom) to a non-ABS
equipped vehicle (on top) during hard braking with
loss of front braking traction.
ABS warning lamp
The
ABSwarning lamp in the instrument cluster
momentarily illuminates when the ignition is turned
on and the engine is off. If the light does not
illuminate momentarily at start up, remains on or
continues to flash, the ABS needs to be serviced.
With the ABS light on,
the anti-lock brake
system is disabled and
normal braking is still
effective unless the brake warning light also remains
illuminated with parking brake released. (If your
brake warning lamp illuminates, have your vehicle
serviced immediately).
Using ABS
²In an emergency or when maximum efficiency
from the ABS is required, apply continuous full
force on the brake. The ABS will be activated
immediately, thus allowing you to retain full
steering control of your vehicle and, providing
there is sufficient space, will enable you to avoid
obstacles and bring the vehicle to a controlled
stop.
²The Anti-Lock system does not decrease the time
necessary to apply the brakes or always reduce

(when the ignition is turned ON) until the parking
brake is released.
Always set the parking brake fully and make
sure that the gearshift is securely latched in
P (Park) (automatic transmission) or in 1 (First
Gear) (manual transmission).
The parking brake is not recommended to stop a
moving vehicle. However, if the normal brakes fail,
the parking brake can be used to stop your vehicle
in an emergency. Since the parking brake applies
only the rear brakes, the vehicle's stopping distance
will increase greatly and the handling of your vehicle
will be adversely affected.
To release the parking
brake, the brake handle
may need to be pulled
up slightly to release
pressure before
pushing in the button.
Push the button on the
end of the parking
brake handle and push the handle down as far as
possible. Driving with the parking brake applied will
cause the brakes to wear out quickly and reduce fuel
economy.
TRACTION CONTROLY(IF EQUIPPED)
Your vehicle may be equipped with the optional
Traction Controlysystem. This system helps you
maintain the stability and steerability of your
vehicle. It is especially useful on slippery and/or hilly
road surfaces. The system operates by detecting and
controlling wheel spin. The system borrows many of
the electronic and mechanical elements already
present in the anti-lock braking system (ABS).
Wheel-speed sensors allow excess rear wheel spin to
be detected by the Traction Controlyportion of the
ABS computer. Any excessive wheel spin is

To prevent damage to the power steering pump:
²Never hold the steering wheel to the extreme
right or the extreme left for more than a few
seconds when the engine is running.
²Do not operate the vehicle with a low power
steering pump fluid level.
If the power steering system breaks down (or if the
engine is turned off), you can steer the vehicle
manually, but it takes more effort.
If the steering wanders or pulls, the condition could
be caused by any of the following:
²underinflated tire(s) on any wheel(s)
²high crown in center of road
²high crosswinds
²wheels out of alignment
²loose or worn components in steering linkage
AUTOMATIC TRANSMISSION OPERATION
(IF EQUIPPED)
Brake-shift interlock
This vehicle is equipped with a brake-shift interlock
feature that prevents the gearshift from being moved
from P (Park) unless the brake pedal is depressed.
If you cannot move the gearshift out of P (Park)
with the brake pedal depressed:
1. Apply the parking brake, turn ignition key to
LOCK, then remove the key.
2. Insert the key and turn it to OFF. Apply the brake
pedal and shift to N (Neutral).
3. Start the vehicle.
If it is necessary to use the above procedure to
move the gearshift, it is possible that a fuse has
blown or the vehicle's brakelamps are not operating
properly. Refer toFuses and relaysin theRoadside
emergencieschapter.

P (Park)
Always come to a
complete stop before
shifting into P (Park).
Make sure the gearshift
is securely latched in P
(Park). This position
locks the transmission
and prevents the rear
wheels from turning.
Always set the
parking brake
fully and make sure
the gearshift is
securely latched in P
(Park).
Never leave your vehicle unattended while it
is running.
R (Reverse)
With the gearshift in R
(Reverse), the vehicle
will move backward.
Always come to a
complete stop before
shifting into and out of
R (Reverse).

MANUAL TRANSMISSION OPERATION
(IF EQUIPPED)
Using the clutch
Vehicles equipped with a manual transmission have a
starter interlock that prevents cranking the engine
unless the clutch pedal is fully depressed.
When starting a vehicle with a manual transmission,
you must:
1. Put gearshift in N
(Neutral).
2. Hold down brake
pedal.
3. Depress clutch
pedal.
4. Turn ignition to
position 5 (START) to
start the engine, let the
engine idle for a few
seconds, then shift into
gear.
5. Release the brake
pedal.
6. Release clutch slowly
while pressing down
slowly on the
accelerator pedal.
²Do not drive with your foot resting on the clutch
pedal and do not use the clutch to hold your
vehicle at a standstill while waiting on a hill.
These actions will seriously reduce clutch life.

Power distribution box
The power distribution box is located in the engine
compartment. The power distribution box contains
high-current fuses that protect your vehicle's main
electrical systems from overloads.
Always disconnect the battery before
servicing high current fuses.
Always replace the cover to the Power
Distribution Box before reconnecting the
battery or refilling fluid reservoirs.
If the battery has been disconnected and
reconnected, refer to theBatterysection of the
Maintenance and Carechapter.
