Parking
Always come to a complete stop and
continue to depress the brake pedal.
Move the shift lever into the P (Park)
position, apply the parking brake,
and place the ignition switch in the
LOCK/OFF position. Take the Key
with you when exiting the vehicle.
Good Driving Practices
Never move the shift lever from P(Park) or N (Neutral) to any other
position with the accelerator pedal
depressed.
Never move the shift lever into P (Park) when the vehicle is in
motion.
Be sure the vehicle is completely
stopped before you attempt to shift
into R (Reverse) or D (Drive).
Do not move the shift lever to N (Neutral) when driving. Doing so
may result in an accident because
of a loss of engine braking and the
transmission could be damaged.
Do not drive with your foot resting on the brake pedal. Even light, but
consistent pedal pressure can
result in the brakes overheating,
brake wear and possibly even
brake failure.
Depressing both accelerator and brake pedals at the same time can
trigger logic for engine power
reduction to assure vehicle decel-
eration. Vehicle acceleration will
resume after the brake pedal is
released. When driving in Manual shift mode,
slow down before shifting to a
lower gear. Otherwise, the lower
gear may not be engaged if the
engine rpms are outside of the
allowable range.
Always apply the parking brake when leaving the vehicle. Do not
depend on placing the transmis-
sion in P (Park) to keep the vehicle
from moving.
Exercise extreme caution when driving on a slippery surface. Be
especially careful when braking,
accelerating or shifting gears. On a
slippery surface, an abrupt change
in vehicle speed can cause the
drive wheels to lose traction and
may cause loss of vehicle control
resulting in an accident.
Optimum vehicle performance and economy is obtained by smoothly
depressing and releasing the
accelerator.
When you stay in the vehicle
with the engine running, be
careful not to depress the accel-
erator pedal for a long period of
time. The engine or exhaust
system may overheat and start
a fire.
The exhaust gas and the
exhaust system are very hot.
Keep away from the exhaust
system components.
Do not stop or park over flam-
mable materials, such as dry
grass, paper or leaves. They
may ignite and cause a fire.
WARNING

Driving your vehicle
Power Brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
You can still stop your vehicle by
applying greater force to the brake
pedal than typical. The stopping dis-
tance, however, will be longer than
with power brakes.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces.

Take the following precautions:
Do not drive with your foot
resting on the brake pedal.
This will create abnormal high
brake temperatures, exces-
sive brake lining and pad
wear, and increased stopping
distances.
When descending a long or
steep hill, shift to a lower gear
and avoid continuous applica-
tion of the brakes. Applying
the brakes continuously will
cause the brakes to overheat
and could result in a tempo-
rary loss of braking perform-
ance.
(Continued)
(Continued)
Wet brakes may impair the
vehicle's ability to safely slow
down; the vehicle may also
pull to one side when the
brakes are applied. Applying
the brakes lightly will indicate
whether they have been
affected in this way. Always
test your brakes in this fash-
ion after driving through deep
water. To dry the brakes, light-
ly tap the brake pedal to heat
up the brakes while maintain-
ing a safe forward speed until
brake performance returns to
normal. Avoid driving at high
speeds until the brakes func-
tion correctly.

Disc Brakes Wear Indicator
When your brake pads are worn and
new pads are required, you will hear
a high pitched warning sound from
your front or rear brakes. You may
hear this sound come and go or it
may occur whenever you depress
the brake pedal.
Please remember some driving con-
ditions or climates may cause a
brake squeal when you first apply (or
lightly apply) the brakes. This is nor-
mal and does not indicate a problem
with your brakes.
To avoid costly brake repairs, do
not continue to drive with worn
brake pads.
Information

plete front or rear axle sets.
