Parking on Hills
You really should not park your vehicle, with a trailer
attached,
on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a
hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet, or into gear for a manual transmission.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes, Then apply your
parking brake, and then shift to
PARK (P) for an
automatic transmission, or
REVERSE (R) for a
manual transmission.
5. Release the regular brakes.
When You Are Ready to Leave After
Parking on
a Hill
1. Apply your regular brakes and hold the pedal down
while
you:
0 Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on
this. Things that are especially important in trailer
operation
are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, drive belts, cooling
system and brake adjustment. Each of these is covered
in
this manual, and the Index will help you find them
quickly. If you’re trailering, it’s a good idea to review
this information before you start your trip.
Check periodically to
see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

Engine Oil Additives
Don’t add anything to your oil. Your dealer is ready to
advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you, use the short tripjcity
maintenance schedule:
0
0

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures
are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use
a carrier on top
of your vehicle.
The vehicle is used for delivery service, police,
taxi or other commercial application.
Driving under these conditions causes engine oil to
break down sooner. If any one of these is true for your
vehicle, then you need to change your oil and filter every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first. If
none of them is true, use the long triphighway
maintenance schedule. Change the oil and filter every
7,500 miles (1 2 500 km) or 12 months -- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine
oil to
break down slower.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t let used
oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil. (See
the manufacturer’s warnings about the use and disposal
of oil products.)
Used oil can be a real threat
to the environment. If you
change your own oil, be sure to drain all free-flowing
oil from the filter before disposal. Don’t ever dispose
of oil by putting it in the trash, pouring it on the ground,
into sewers,
or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil. If
you have a problem properly disposing
of your used oil,
ask your dealer, a service station or a local recycling
center for help.

Air Cleaner
Refer to the Maintenance Schedule to determine when to
replace the
air filter.
See “Scheduled Maintenance Services”
in the Index.
/! CAUTION:
-
Operating the engine with the air cleaner off can
cause you
or others to be burned. The air cleaner
not
only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires, you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the
air cleaner off.
I NOTICE: I
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your engine, which will damage it. Always
have the air cleaner in place when you’re driving.
6-18

If you have the 5.7L V8 engine (with the WS6 option),
your air cleaner will be located over the radiator near the
front of the engine.
To remove the filter, remove the screws (located on the
rear edge of the air cleaner), lift the
air cleaner and
remove the filter.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when
the engine oil is changed.
Change both the fluid and filter every
15,000 miles
(25 000 km) if the vehicle is mainly driven under one
or more
of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
In hilly or mountainous terrain.
Uses such as high performance operation.
When doing frequent trailer towing.
0 Uses such as found in taxi, police or delivery service.
If you
do not use your vehicle under any of these
conditions, change the fluid and filter every
50,000 miles (83 000 km).
See “Scheduled Maintenance Services” in the Index.
6-20

3. Check both sides of the dipstick, and read the lower
level.
The fluid level must be in the COLD area for a
cold check or in the
HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all the way.
How to Add Fluid
Refer to the Maintenance 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
while it is 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’t ove@ZZ.
I NOTICE:
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.
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.
Manual Transmission Fluid
When to Check
A good time to have it checked is when the engine
oil is changed. However, the fluid in your manual
transmission doesn’t require changing.
6-24

How to Add Fluid When to Check and What to Use
Here’s how to add fluid. Refer to the Maintenance
Schedule to determine what kind of fluid to use. See
“Recommended Fluids and Lubricants” in the Index.
1. Remove the filler plug.
2. Add fluid at the filler plug hole. Add only enough
fluid to bring the fluid level
up to the bottom of the
filler plug hole.
3. Install the filler plug. Be sure the plug is fully seated.
Hydraulic Clutch
The hydraulic clutch linkage in your vehicle is
self-adjusting. The clutch master cylinder reservoir is
filled with hydraulic clutch fluid.
It isn’t
a good idea to “top off’ your clutch fluid. Adding Refer to the Maintenance Schedule to determine how
fluid won’t correct a leak. often you should check the fluid level in your clutch
A fluid loss in this system could indicate a problem. master cylinder reservoir and
for the proper fluid. See
Have the system inspected
and repaired. “Owner Checks and Services’’ and “Recommended
Fluids and Lubricants” in the Index.
6-26

How to Check Limited-Slip Differential
The proper fluid should be added if the level is below
the
STEP mark on the reservoir. See the instructions on
the reservoir cap.
Rear Axle
When to Check and Change Lubricant
Refer to the Maintenance Schedule to determine how
often to check the lubricant and when to change it. See
“Scheduled Maintenance Services” 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.
What to Use
Standard Differential
Use SAE 75W-90 Synthetic Gear Lubricant (GM Part
No. 12378261) or equivalent meeting GM
Specification
9986 1 15.
To add lubricant when the level is low, use SAE 75W-90
Synthetic Gear Lubricant (GM Part No. 12378261) or
equivalent meeting
GM Specification 99861 15. To
completely refill after draining, add
4 ounces (1 18 ml)
of Limited-Slip Differential Lubricant Additive (GM
Part No. 1052358) or equivalent. Then fill to the bottom
of the filler plug hole with Synthetic Gear Lubricant.
Engine Coolant
The cooling s stem in your vehicle is filled with
DEX-COOL
8 engine coolant. This coolant is designed
to remain in your vehicle for
5 years or 150,000 miles
(240
000 kmb whichever occurs first, if you add only
DEX-COOL extended life coolant.
The following explains your cooling system and
how
to add coolant when it is low. If you have a problem
with engine overheating or if you need to add coolant to
your radiator, see “Engine Overheating” in the Index.
6-27

There are only two reasons why the brake fluid level in the
reservoir 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 put 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.
A CAUTION:
If you have too much brake fluid, it can spill on the
engine. The
fluid will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid only
when work is done on the brake hydraulic system.
Refer to the Maintenance Schedule to determine when to
check your brake fluid. See “Periodic Maintenance
Inspections”
in the Index.
Checking Brake Fluid
You can check the brake fluid without taking off the cap.
Just look
at the brake fluid reservoir. The fluid level
should be above the plastic
seam in the reservoir. If it
isn’t, have your brake system checked
to see if there
is
a leak.
After work is done on the brake hydraulic system,
make
sure the level is above the plastic seam, near the base of
the filler neck.

What to Add
When you do need brake fluid, use only DOT-3 brake
fluid. Use new brake fluid from a sealed container only.
Refer
to “Recommended Fluids and Lubricants” in the
Maintenance Schedule.
Always clean the brake fluid reservoir cap and the area
around the cap before removing it. This will help keep
dirt from entering the reservoir.
With the wrong kind
of fluid in your brake
system, your brakes may not work well, or they
may not even work
at all. This could cause a
crash. Always use the proper brake fluid.
NOTICE:
Using the wrong fluid can badly damage
brake system parts. For example, just
a few
drops of mineral-based oil, such
as engine
oil, in your brake system can damage brake
system parts
so badly that they’ll have to
be replaced. Don’t let someone put in the
wrong kind of fluid.
If you spill brake fluid on your vehicle’s
painted surfaces, the paint
finish can be
damaged. Be careful not to spill brake fluid
on your vehicle.
If you do, wash it off
immediately. See “Appearance Care” in
the Index.
Brake Wear
Your vehicle has four-wheel disc 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).
