If your vehicle is equipped with front compartment
underhood sight shields, before closing the
hood be sure to reinstall the sight shields. To
reinstall the shields, locate the tabs on the left and
right sides and insert them into the openings in
the tower to tower brace. Then insert the fasteners
into the top of the shield and push the fasteners
back into place.

It is located between the battery and the
underhood fuse block. You should always use
this remote ground location, instead of the
terminal on the battery.
Notice:If you connect a negative cable to the
ECM, ECM mounting bracket, or any cables
that attach to the ECM bracket, you may
damage the ECM. Always attach the negative
cable to your vehicle’s remote negative ground
location, instead of the ECM, ECM bracket,
or any cables attached to the ECM bracket.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need more
light. Be sure the battery has enough
water. You do not need to add water to the
battery installed in your new vehicle. But if
a battery has ller caps, be sure the right
amount of uid is there. If it is low, add
water to take care of that rst. If you do not,
explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.

Electrical System
Add-On Electrical Equipment
Notice:Do not add anything electrical to your
vehicle unless you check with your dealer
rst. Some electrical equipment can damage
your vehicle and the damage would not
be covered by your warranty. Some add-on
electrical equipment can keep other
components from working as they should.
Add-on equipment can drain your vehicle’s battery,
even if your vehicle is not operating.
Your vehicle has an airbag system. Before
attempting to add anything electrical to your
vehicle, seeServicing Your Airbag-Equipped
Vehicle on page 78.
Headlamp Wiring
The headlamp wiring is protected by fuses in the
fuse block. An electrical overload will cause
the lamps to turn off. If this happens, have your
headlamp wiring checked right away.
Windshield Wiper Fuses
The windshield wiper motor is protected by an
internal circuit breaker. If the wiper motor
overheats due to heavy snow, the wipers will stop
until the motor cools and will then restart.
486

Power Windows and Other Power
Options
Circuit breakers protect the power windows and
power seats. When the current load is too
heavy, the circuit breaker opens and closes,
protecting the circuit until the problem is xed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected
from short circuits by a combination of fuses,
circuit breakers and fusible thermal links.
This greatly reduces the chance of res caused by
electrical problems.Look at the silver-colored band inside the fuse. If
the band is broken or melted, replace the fuse.
Be sure you replace a bad fuse with a new one of
the identical size and rating. If a fuse should
blow, see your dealer for service immediately.
If you ever have a problem on the road
and don’t have a spare fuse, you can borrow
one that has the same amperage. Just pick some
feature of your vehicle that you can get along
without – like the radio or cigarette lighter – and
use its fuse, if it is the correct amperage. Replace
it as soon as you can.
The fuses are located in three fuse blocks.
One is located in the engine compartment, on the
passenger’s side of the vehicle, and the other
two are located under the rear seat on both the
driver’s and passenger’s side of the vehicle.

Underhood Fuse Block
488

The underhood fuse block is located in the front of
the engine compartment on the passenger’s
side of the vehicle. SeeEngine Compartment
Overview on page 373for more information
on location and removal procedure for the front
compartment underhood sights shields.
To access the fuses, push in the tabs located on
each side of the fuse block cover, then lift the
cover off.

492

{CAUTION:
A safety belt that is not properly routed
through the seat cushion or is twisted will
not provide the protection needed in a
crash. If the safety belt has not been
routed through the seat cushion at all, it
will not be there to work for the next
passenger. The person sitting in that
position could be badly injured. After
reinstalling the seat cushion, always
check to be sure that the safety belts are
properly routed and are not twisted.
1. Buckle the center passenger position safety
belt, then route the safety belts through the
proper slots in the seat cushion. Do not let the
safety belts get twisted.
2. Slide the rear of the cushion up and under the
seatback so the rear-locating guides hook into
the wire loops on the back frame.3. With the seat cushion lowered, push rearward
and then press down on the seat cushion until
the spring locks on both ends engage.
4. Check to make sure the safety belts are
properly routed and that no portion of any
safety belt is trapped under the seat.
Also make sure the seat cushion is secured.
Rear Underseat Fuse Block
There is a fuse block located under the rear seat
on the driver’s side and passenger’s side of
the vehicle. The rear seat cushion must be
removed to access the fuse blocks. See
“Removing the Rear Seat Cushion” listed
previously in this section.
To access the fuses, push in the two tabs, then lift
the cover off.
