Add enough lubricant
to raise the level to the
bottom
of the filler
plug hole.
The arrow on the left shows the drain plug location. The arrow
on the right

the bottom of the filler
plug hole, you’ll need to add some lubricant.

Downloaded from www.Manualslib.com manuals search engine If the differential is at operating temperature (w,arm), add enou\
gh lubricant
to raise the level to the bottom of the filler plug hole.
If the differential is cold, add enough lubricant to raise the level to 1/2 inch
(12
mm) below the filler plug hole.
What to use
Refer to the Maintenance Schedule to determine what kind of lubricant to
use. See “Recommended Fluids and Lubricants” in the Index.
Engine Coolant
The following explains your cooling system and how to add coolant \
when it
is low.
If you have a problem with engine overheating, see “Engine
Overheating” in the Index.
The proper coolant for your vehicle will:
Give freezing protection down to -20 “F (-29” C), or -34°F (-37 “C) in
Canada and for vehicles with the cold climate option.
e Give boiling protection up to 258°F (125°C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they should.
What to Use
Use a mi,xture of one-half clean water (preferably distilled) and one-half
antifreeze that meets “GM Specification 603%” or “GM Specification
6043-M ”for the 2.2L (LN2) Code 4 engine, which won’t damage
aluminum parts. You can also use
a recycled coolant conforming to “GM
Specification 603%” or “GM Specification 6043-M ”for the 2.2L (LN2)
Code 4 engine with a complete coolant flush and refill.
If you use this
mixture, you don’t need to add anything else.

NOTICE:
When adding power steering fluid or making a complete fluid
change, always use the proper fluid. Failure to use the proper\

fluid can cause leaks and damage hoses and seals.

Brake Master Cylnder
Your brake master
cylinder is here. It is
filled with
DOT-3
brake fluid.
There are only two reasons why the brake fluid level
in your master cylinder
might go down, The first is that the brake fluid goes down to an acceptable
level during normal brake lining wear. When new linings are pu\
t in, the
fluid level goes back up. The other reason is that fluid is leaking out of the
brake system.
If it is, you should have your brake system fixed, since a leak
means that sooner or later your brakes won’t work well, or \
won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid
won’t correct a leak.
If you add fluid when your linings are worn, then
you’ll have too much fluid when you get new brake linings.
You should add
(or remove) brake fluid, as necessary, only when work is done on the brake
hydraulic system.
Refer to the Maintenance Schedule to determine when to check y\
our brake fluid. See “Periodic Maintenance Inspections” in the Index.

Downloaded from www.Manualslib.com manuals search engine Other Maintenance Items
Front Suspension and Steering Linkage
Refer to the Maintenance Schedule to determine how often to lubricate the
fittings and what type
of lubricant to use.
Front Wheel Bearings (Two-Wheel Drive)
If your vehicle is two-wheel drive, it has wheel bearings that must be
cleaned and repacked.
Refer to the Maintenance Schedule to determine how often this must be
done.
Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, and more durable
than systc
.s with several belts.
The belt runs over or around the pulleys on the engine. A tensioner is used
to keep the belt tight at all times. The tensioner also makes replacing the
belt easier if you need to replace the belt, be sure
to get the correct
replacement belt. Your dealership or parts supplier can help you with this.
The Accessory Drive Belt Routing label on your vehicle will show y\
ou how
to route the belt your vehicle uses.
Windshield Wiper Blade Replacement
NOTICE:
Use care when removing or installing a blade assembly.
Accidental bumping can cause the arm to fall back and strike
the windshield.

Downloaded from www.Manualslib.com manuals search engine Lubrication
Accelerator Control System
Refer to the Maintenance Schedule to determine how often the a\
ccelerator linkage pivot points must be lubricated and what type
of lubricant to use.
Accelerator cables and cruise control cables should not be lubr\
icated. Any
cables that are worn or are hard
to pull should be replaced.
When cleaning the engine compartment with water or steam, avoid\
directing the flow onto the throttle linkage
in a manner that would cause moisture to
enter the cables.
Hood Latches and Hood Hinge
Refer to the Maintenance Schedule to determine how to lubricate\
the hood
latch and hood hinge assembly.
Propeller Shaft Slip Splines/Universal Joints
Refer to the Maintenance Schedule to determine how often the slip and
universal joints must be lubricated and what type
of lubricant to use.
Body
Normal use of your vehicle will cause metal to metal wear at some points on
the cab and body if they are not lubricated.
For exposed surfaces, such as door checks, door lock bolts, lock s\
triker
plates, dovetail bumper wedges, etc., a thin film
of engine oil should be
applied.
Where oil holes are provided in the body or cab, a dripless oil can be used.
The seat adjusters and seat track should be lubricated with chassis\
grease.
Door weatherstrips and rubber hood bumpers should be wiped clea\
n with a wet cloth and lightly coated with a rubber lubricant.
Never use too much
of any lubricant and be sure to wipe up any extra
lubricant when you are finished.
Window regulators and controls are inside the doors. They are lubricated
with a long lasting grease.
If lubrication is required your dealer should
perform this service.
Refer to the Maintenance Schedule to determine how often to lubricate
these items and what type of lubricant to use.

Downloaded from www.Manualslib.com manuals search engine Lock Cylinders
To be sure your locks operate properly, they must be lubricated.
Refer to the Maintenance Schedule to determine
how often to lubricate them
and what type
of lubricant to use.
You should not use penetrating oils because they could wash out the factory
installed lubricant and cause
the lock to bind. De-icers which contain
alcohol could
also wash away the lubricant, so be sure to lubricate the lock
after using a de-icer of this type.
Tailgate Handle
The tailgate handle pivot points on your vehicle should be lubricated to keep
the handle working smoothly.
Refer to the Maintenance Schedule to determine
how often to lubricate them
and what type
of lubricant to use.
Exhaust System
To help prevent damage to your exhaust system, do not continue to drive
your vehicle if you notice:
Engine misfiring
Loss of performance
Other unusual operating conditions
Have your engine and exhaust system serviced regularly.
Three- Way Catalytic Converter
Your vehicle's three-way catalytic converter is designed to reduce the
pollutants in your vehicle's exhaust. Use only unleaded fuel in your vehicle.
If you use leaded fuel, you could damage your three-way catalytic converter
and other engine components.
Malfunction Indicator Lamp (SERVICE ENGINE SOON )
This light on your instrument panel lets you know when your emission
system needs service. The light will come on briefly when you start your
engine to let you know that the system
is working. If it does not come on
when you start your engine, or if it comes on and stays on while you're
driving, your system may
need service. Your vehicle should still be
driveable, but you should have your system serviced right away.

To make your tires last longer, have them inspected and rotated at the
mileages recommended in the Maintenance Schedule. See “Schedul\
ed
Maintenance Services” in the Index.
Use this rotation
pattern.
The four wheel rotation is for aluminum wheels only. The five wheel
rotation is for steel wheels only.
If your vehicle has front tires with different load ratings or tr\
ead designs
(such as all season vs. ordoff road) than the rear tires, d\
on’t rotate your tires
front to rear.
After the tires have been rotated, adjust the front and rear inflation pressure
as shown on the CertificatiodTire label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the Index.
