Lubricants on page 11‑6.
Front Axle
When to Check and Change
Lubricant
It is not necessary to regularly
check the front axle fluid unless
there is a leak suspected or an
unusual noise is heard. A fluid loss
could indicate a problem. Have it
inspected and repaired.
How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
If the level is below the bottom of
the filler plug hole, located on the
front axle, some lubricant may need
to be added.
When the differential is cold, add
enough lubricant to raise the level to
12 mm (1/2 in) below the fill
plug hole. When the differential is at operating
temperature (warm), add enough
lubricant to raise the level to the
bottom of the fill plug hole.
What to Use
See
Recommended Fluids and
Lubricants on page 11‑6.
Rear Axle
When to Check and Change
Lubricant
It is not necessary to regularly
check rear axle fluid unless there is
a leak suspected or an unusual
noise is heard. A fluid loss could
indicate a problem. Have it
inspected and repaired.

How to Check Lubricant
To get an accurate reading, the
vehicle should be on a level
surface.
The proper level is from 0 mm to
10 mm (0 to 3/8 in) below the bottom
of the fill plug hole, located on the
rear axle.
What to Use
SeeRecommended Fluids and
Lubricants on page 11‑6 to
determine which kind of lubricant
to use.

Wiper Blade Replacement
Windshield wiper blades should be
inspected for wear and cracking.
See Scheduled Maintenance on
page 11‑2 for more information.
Replacement blades come in
different types and are removed in
different ways. For proper type and
length, see Maintenance
Replacement Parts on page 11‑9.
Allowing the wiper blade arm to
touch the windshield when no wiper
blade is installed could damage the
windshield. Any damage that occurs would not be covered by the vehicle
warranty. Do not allow the wiper
blade arm to touch the windshield.
1. To remove the old wiper blades,
lift the wiper arm until it locks
into a vertical position.

the factory and should need no
further adjustment.
However, if the vehicle is damaged
in a crash, the headlamp aim may
be affected. Aim adjustment to the
low-beam headlamps may be
necessary if oncoming drivers flash
their high-beam headlamps at you
(for vertical aim).
If the headlamps need to be
re-aimed, it is recommended that
the vehicle be taken to the dealer

10-40 Vehicle Care
Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit
until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by
electrical problems.
Fuses and circuit breakers protect
the following in the vehicle:
.Headlamp Wiring
.Windshield Wiper Motor
.Power Windows and Other
Power Accessories
Replace a bad fuse with a new one
of the identical size and rating. If there is a problem on the road and
a fuse needs to be replaced, the
same amperage fuse can be
borrowed. Choose some feature of
the vehicle that is not needed to use
and replace it as soon as possible.
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have the
headlamp wiring checked right away
if the lamps go on and off or
remain off.
Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected
from electrical overload, overload
due to heavy snow or ice may
cause wiper linkage damage.
Always clear ice and heavy snow
from the windshield before using the
windshield wipers.If the overload is caused by an
electrical problem and not snow or
ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses and circuit
breakers. 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.
If you ever have a problem on the
road and do not have a spare fuse,
you can borrow one that has the
same amperage. Just pick some
feature of the 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.
