Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information label
found on the rear edge of the driver's door tells you the
proper size, speed rating and recommended inflation
pressures for the tires on your vehicle. It also gives you
important information about the number of people that can be in your vehicle and the total weight that you can
carry. This weight is called the Vehicle Capacity Weight
and includes the weight
of all occupants, cargo, and all
nonfactory-installed options.

Fuses and Circuit Breakers
The wiring circuits in your car are protected from short
circuits by a combination of fuses, circuit breakers, and
fusible thermal links in the wiring itself.. This greatly
reduces the chance of fires caused by electrical
problems.
Be sure to use the correct fuse if you need to replace
one.
If you ever have a problem on the road and don’t
have a spare fuse, you can “borrow” one
of the correct
value. Just pick some feature
of your car that you can
get along without
- like the radio or cigarette lighter -
and use its fuse, if it is of the value you need. Replace it
as soon as you can.
There are two fuse block areas inside your vehicle. One is located on the left side of the console under a carpeted
panel cover. Remove the cover to access the fuses.

Headlights
The headlight wiring is protected by a circuit breaker in
the light switch.
An electrical overload will cause the
lights to go on and
off, or in some cases to remain off. If
this happens, have your headlight wiring checked right away.

Follow the stem below.
I
1. Before you start, be sure you have
enough room around the vehicle.
2. Firmly apply both the parking brake (see “Parking Brake” in the Index if
necessary) and the regular brake.
NOTE: Do not use the accelerator
pedal, and be ready to
turn off the
engine immediately if it starts.
3. Try to start the engine in each gear.
The starter should work only
in “P”
(Park) or “N” (Neutral). If the starter
works in any other position, your
vehicle needs service.

INSPECTION OR SERVICE
Brake System
Inspection
WHAT SHOULD BE DONE
Inspect the complete system. Inspect
brake lines and hoses for proper
hookup, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads
for wear and rotors for surface
condition. Inspect other brake parts, including calipers, parking brake,
etc. Check parking brake
adjustment. You may need to have
your brakes inspected more often if
your driving habits or conditions
result in frequent braking.
NOTE: A low brake fluid level can
indicate worn disc brake pads which
may need to be serviced. Also, if the
brake system warning light stays on
or comes on, something may be
wrong with the brake system. See
“Brake System Warning Light” in
the Index. If your anti-lock brake
system warning light stays on or
comes
-on, something may be wrong
with the anti-lock brake system. See “Anti-Lock Brake System Warning
Light” in the Index.
