NOTICE:
If you use an improper coolant mixture, your
engine could overheat and be badly damaged.
The repair cost wouldn't be covered by your
warranty. Too much water in the mixture can
freeze and crack the engine, radiator, heater
core and other parts.
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
NOTICE:
If you use the proper coolant, you don't have to
add extra inhibitors or additives which claim to
improve the system. These can be harmful.
Checking Coolant
The coolant recovery tank is located between the power
steering fluid reservoir and the underhood fuse block in
the engine compartment on the passenger's side of the
vehicle. See ªEngine Compartment Overviewº in the
Index for more information on location.

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.
Headlamp Wiring
The headlamp circuit is protected by individual fuses in
the underhood fuse block. An electrical overload will
cause the fuse to blow. If this happens, have your
headlamp system checked right away.
Windshield Wipers
The windshield wiper motor is protected by a 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, have
it fixed.
Power Windows and Other Power Options
A circuit breaker in the driver's side instrument panel
fuse block protects 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.

6-62 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 in the wiring itself.
This greatly reduces the chance of fires 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.
Driver's Side Instrument Panel Fuse Block
Some fuses are in a fuse
block at the end of the
instrument panel on the
driver's side of the vehicle.
Pull off the cover labeled
FUSES to expose the fuses.
