Headlight Wiring
The headlight wiring is protected by a
circuit breaker in the component center.
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 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
Circuit breakers in the 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.

qualified service center should perform.
“Section D: Recommended Fluids
