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 on
the passenger's side of the engine compartment.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
COLD mark or a little higher. When your engine is
warm, the level should be up to the HOT mark
or a little higher.

6-61 Headlamp Wiring
The headlamp circuit is protected by individual fuses in
the underhood electrical center. 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 fuse panel 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.
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.
