in your clutch master
cylinder reservoir and
for the proper fluid.
See “Owner Checks and Services” and “Recommended Fluids and
Lubricants”
in the Index.
How to Check
The proper fluid should be added if the level does not reach the bottom of
the diaphragm when it’s in place in the reservoir. See the instructions on the
reservoir cap.

Four- Wheel Drive
Most lubricant checks in this section also apply to four-wheel-drive
vehicles. However, they have two additional systems that need lubrication.
Transfer Case
When to Check Lubricant
Refer to the Maintenance Schedule to determine how often to check the
lubricant. See “Periodic Maintenance Inspections”
in the Index.
How to Check Lubricant
If the level is below
the bottom of
the filler
plug hole, you’ll need
to add some lubricant.
Add enough lubricant
to raise the level
to the
bottom
of the filler
plug hole.

Your vehicle has front disc brakes and rear drum brakes.
Disc brake pads
have built-in wear indicators that make a high-pitched
warning sound when the brake pads are worn and new pads are needed. The
sound may come and
go or be heard all the time your vehicle is moving
(except when you are pushing on the brake pedal firmly).
I NOTICE:
Continuing to drive with worn-out brake pads could result in
costly brake repair.
Some driving conditions or climates may cause a brake squeal when the
brakes are first applied or lightly applied. This does not mean something is
wrong with your brakes.
Your rear drum brakes don’t have wear indicators, but
if you ever hear a
rear brake rubbing noise, have the rear brake linings inspected. Also, the
rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When
you have the front brakes replaced,
have
the rear brakes inspected, too.
Brake linings should always be replaced as complete axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to normal height, or if
there
is a rapid increase in pedal travel. This could be a sign of brake
trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes adjust for wear.
If your brake pedal goes down farther than normal, your rear drum brakes
may need adjustment. Adjust them by backing up and firmly applying the
brakes a few times.

NOTICE:
If your vehicle has LT265/75R16 size tires, don't use tire chains;
they can damage your vehicle.
If you have
a tire size other than LT26975R16, use tire chains
only where legal and only when you must. Use chains that are
the proper size for your tires. Install them on the tires
of the rear
axle.
Don't
use chains on the tires of the front axle.
Tighten them as tightly as possible with the ends securely
fastened. Drive slowly and follow the chain manufacturer's
instructions. If you can hear the chains contacting your vehicle,
stop and retighten them. If the contact continues, slow down
until it stops. Driving too fast or spinning the wheels with chains
on will damage your vehicle.
Appearance Care
. ..
. ..
Remember, cleaning products can be hazardous. Some are toxic. Others can
burst into flame if
you strike a match or get them on a hot part of the
vehicle. Some are dangerous
if you breathe their fumes in a closed space.
When
you use anything from a container to clean your vehicle, be sure to
follow the manufxturer's warnings and instructions. And always open your
doors or windows when you're cleaning
the inside.

Downloaded from www.Manualslib.com manuals search engine If your engine has more than one emissions classification, the classification
is determined by the Gross Vehicle Weight Rating (GVWR) of your vehicle
as shown on the Certification Label. See “Loading Your Vehicle” in the
Index.
Once you’ve determined your engine type and,
if necessary, emissions
classification, you’ll need
to decide which of the two schedules is right for
your vehicle. See Definitions for Maintenance Schedule I and Maintenance
Schedule I1 following.
Schedule I Definition - Gasoline Engines With Light Duty
