Downloaded from www.Manualslib.com manuals search engine How to Add Fluid
Refer to the Mainterl‘ance Schedule to determine what
kind of transmission fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
Add fluid
only after checking the transmission fluid HOT.
(A COLD check is used only as a reference.) If the fluid
level is low, add only enough of the proper fluid
to bring
the level up
to the HOT area for a hot check. It doesn’t
take.much fluid, generally less than
one pint (0.5 L).
Don P overjill.
I NOTICE:
-
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down
to lock the dipstick in place.
All-Wheel Drive
If you have an all-wheel-drive vehicle, be sure to
perform
the lubricant checks described in this section.
However,
they have two additional systems that
need lubrication.
Transfer Case
We recommend you use only fluid labeled
DEXRON@-111, because fluid with that label is
made especially for your automatic transmission.
Damage caused by fluid other than
DEXRON-I11
is not covered by your new vehicle warranty. When to Check Lubricant
Refer to the Maintenance Schedule to determine
how
often to check the lubricant. See “Periodic Maintenance
Inspections’’
in the Index.

Downloaded from www.Manualslib.com manuals search engine Headlamp Wiring
The headlamp wiring is protected by a circuit breaker in
the lamp switch. 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 wiring checked
right away.
Windshield Wiper Fuses
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 and
not snow, etc., be sure
to get 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 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 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.
Spare fuses and a fuse puller are located in the
underhood electrical center. You can remove fuses with
the fuse puller. Remember to replace
any of the spare
fuses
you use, so you will have some if you ever need
them again.
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.
There are two fuse blocks in your vehicle: one is inside
the vehicle and one is
in the engine compartment.
