Power Steering Fluid
The power steering fluid reservoir is located on the rear
passenger side of the engine compartment.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering
fluid unless you suspect there is a leak in the system or
you hear an unusual noise. A fluid loss in this system
could indicate a problem. Have the system inspected
and repaired.
How to Check Power Steering Fluid
Turn the key off, let the engine compartment cool down,
wipe the cap and the top of the reservoir clean, then
unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level on the dipstick.
The level should be at the FULL COLD mark. If
necessary, add only enough fluid to bring the level up to
the mark.
What to Use
To determine what kind of fluid to use, see
ªRecommended Fluids and Lubricantsº in the Index.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.

6-26 Adding Washer Fluid
The washer fluid warning light will come on when the
ignition switch is ON and the fluid container is less than
one
-third full. On vehicles with the optional Driver
Information Center (DIC), a WASHER FLUID LOW
message will be displayed and a chime will sound
letting you know to add windshield washer fluid to
your vehicle.
Open the cap labeled
WASHER FLUID. Add
washer fluid until the tank
is full.
NOTICE:

When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.

Don't mix water with ready
-to-use washer
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn't clean as well as washer fluid.

Fill your washer fluid tank only
three
-quarters full when it's very cold.
This allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.

Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.

6-27
Brakes
Brake Fluid
Your brake master cylinder reservoir is on the driver's
side of the engine compartment. It is filled with
DOT
-3 brake fluid.There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluid
level goes back up. The other reason is that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes won't work well, or won't work
at all.
So, it isn't a good idea to ªtop offº your brake fluid.
Adding brake fluid won't correct a leak. If you add fluid
when your linings are worn, then you'll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.

6-28
When your brake fluid falls to a low level, your brake
warning light will come on. If your vehicle has the
Driver Information Center, the BRAKE FLUID LOW
message will also be displayed. A chime will sound if
you try to drive with this warning light on. See ªBrake
System Warning Lightº in the Index.
What to Add
When you do need brake fluid, use only DOT
-3 brake
fluid. Use new brake fluid from a sealed container only.
Refer to ªRecommended Fluids and Lubricantsº in the
Maintenance Schedule.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
CAUTION:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:

Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral
-based oil, such as engine
oil, in your brake system can damage brake
system parts so badly that they'll have to be
replaced. Don't let someone put in the
wrong kind of fluid.

If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See ªAppearance Careº
in the Index.
Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make a
high
-pitched warning sound when the brake pads are
worn and new pads are needed. The sound may come and
go or be heard all the time your vehicle is moving (except
when you are pushing on the brake pedal firmly).

6-60
Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears on
a plate in the front corner of the instrument panel, on the
driver's side. You can see it if you look through the
windshield from outside your vehicle. The VIN also
appears on the Vehicle Certification and Service Parts
labels and the certificates of title and registration.
Engine Identification
The 8th character in your VIN is the engine code.
This code will help you identify your engine,
specifications and replacement parts.
Service Parts Identification Label
You'll find this label on your spare tire cover. It's very
helpful if you ever need to order parts. On this label is:

your VIN,
the model designation,

paint information and

a list of all production options and
special equipment.
Be sure that this label is not removed from the vehicle.
Electrical System
Add-On Electrical Equipment
NOTICE:
Don't add anything electrical to your vehicle
unless you check with your dealer first. Some
electrical equipment can damage your vehicle
and the damage wouldn't be covered by your
warranty. Some add
-on electrical equipment
can keep other components from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical to your vehicle, see ªServicing
Your Air Bag
-Equipped Vehicleº in the Index.

6-61 Headlamp Wiring
The headlamp wiring is protected by an internal circuit
breaker. An electrical overload will cause the lamps to
go on and off, or in some cases to remain off.
If this happens, have your headlamp system checked
right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker and a fuse. If the motor overheats due to
heavy snow, etc., the wiper will stop until the motor
cools. If the overload is caused by some electrical
problem, be sure to have it fixed.
Power Windows and Other Power Options
Circuit breakers in the rear electrical center protect the
power windows and other power accessories. When the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed or
goes away.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses and circuit
breakers. This greatly reduces the chance of damage
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 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 MaxiFuses are located in two Bussed Electrical
Centers (BEC), one located near the engine
compartment on the passenger's side and the other
under the rear seat on the driver's side. If a MaxiFuse
should blow, have your vehicle serviced by your
dealer immediately.
Removing Fuses
You will find a fuse puller attached in both of the BEC.
Snap the wide end of the fuse puller on to the fuse, at
the side indentations holding the puller and pull the
fuse out.

6-62 Engine Compartment Bussed Electrical
Center (BEC)
As mentioned above, the
front BEC is located in
the front of the engine
compartment on the
passenger's side. Lift the
cover to gain access.
Fuse 22 or 23 can be moved to the outer position to
enable the accessory power outlet or cigarette lighter
when the ignition is not on. See your dealer for
additional assistance, if needed.
