5. If you have a four-wheel-drive vehicle, be sure the
transfer case is in a drive gear ± not in NEUTRAL.
6. Release the regular brakes.
{CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake ®rmly set. Your vehicle can roll.
If you have left the engine running, the vehicle
can move suddenly. You or others could be
injured. To be sure your vehicle won't move,
even when you're on fairly level ground, use the
steps that follow.
Always put the shift lever fully in PARK (P) with
the parking brake ®rmly set.
If the transfer case on four-wheel-drive vehicles
is in NEUTRAL, your vehicle will be free to roll,
even if your shift lever is in PARK (P). So, be
sure the transfer case is in a drive gear Ð not in
NEUTRAL.
When You Are Ready to Leave After
Parking on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
·start your engine,
·shift into a gear, and
·release the parking brake.
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 ¯uid (don't over®ll),
engine oil, axle lubricant, belts, cooling system and
brake system. Each of these is covered in this manual,
and the Index will help you ®nd them quickly. If you're
trailering, it's a good idea to review these sections
before you start your trip.
Check periodically to see that all hitch nuts and bolts
are tight.

When It Is Time for New Tires
One way to tell when it's
time for new tires is to
check the treadwear
indicators, which will
appear when your tires
have only 1/16 inch
(1.6 mm) or less of
tread remaining.
You need a new tire if any of the following statements
are true:
·You can see the indicators at three or more places
around the tire.
·You can see cord or fabric showing through the
tire's rubber.
·The tread or sidewall is cracked, cut or snagged
deep enough to show cord or fabric.
·The tire has a bump, bulge or split.
·The tire has a puncture, cut or other damage that
can't be repaired well because of the size or
location of the damage.
Buying New Tires
To ®nd out what kind and size of tires you need, look at
the Tire-Loading Information label.
Make sure the replacement tires are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your vehicle's original tires.
{CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different sizes
or types (radial and bias-belted tires) the vehicle
may not handle properly, and you could have a
crash. Using tires of different sizes may also
cause damage to your vehicle. Be sure to use
the same size and type tires on all wheels.
{CAUTION:
If you use bias-ply tires on your vehicle, the
wheel rim ¯anges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use only
radial-ply tires with the wheels on your vehicle.

Cleaning Glass Surfaces
Glass should be cleaned often. GM Glass Cleaner or
a liquid household glass cleaner will remove normal
tobacco smoke and dust ®lms on interior glass.
See
Vehicle Care/Appearance Materials on page 5-87.
Notice:If you use abrasive cleaners when
cleaning glass surfaces on your vehicle, you could
scratch the glass and/or cause damage to the
rear window defogger and the integrated radio
antenna. When cleaning the glass on your vehicle,
use only a soft cloth and glass cleaner.
Care of Safety Belts
Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do,
it may severely weaken them. In a crash,
they might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth at least every six
months. During very cold, damp weather more frequent
application may be required. See
Part D: Recommended
Fluids and Lubricants on page 6-30.
Cleaning the Outside of Your
Vehicle
The paint ®nish on your vehicle provides beauty, depth
of color, gloss retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle's ®nish is to keep
it clean by washing it often with lukewarm or cold
water.
Don't wash your vehicle in the direct rays of the sun.
Use a car washing soap. Don't use strong soaps
or chemical detergents. Be sure to rinse the vehicle
well, removing all soap residue completely. You can get
GM-approved cleaning products from your dealer.
See
Vehicle Care/Appearance Materials on page 5-87.

Selecting the Right Schedule
First you'll need to decide which of the two schedules is
right for your vehicle. Here's how to decide which
schedule to follow:
Short Trip/City De®nition
Follow the Short Trip/City Scheduled Maintenance if any
one of these conditions is true for your vehicle:
·Most trips are less than 5 miles (8 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).
·You frequently tow a trailer or use a carrier on top
of your vehicle.
·If the vehicle is used for delivery service, police,
taxi or other commercial application.
One of the reasons you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km):Engine Oil and Filter
Change (or 3 months, whichever occurs ®rst).
Every 6,000 Miles (10 000 km):Passenger
Compartment Air Filter Inspection (If Equipped).
Tire Rotation.
Every 15,000 Miles (25 000 km):Engine Air Cleaner
Filter Inspection. Automatic Transmission Service
(severe conditions only). Manual Transmission Fluid
Change. Transfer Case Fluid Change. Differential Fluid
Change. Propeller Shafts and U-Joints Inspection
(or every 15 months, whichever occurs ®rst).
Every 30,000 Miles (50 000 km):Engine Air Cleaner
Filter Replacement. Air Filter Replacement (If Equipped).
Ignition Coil Plug Cap Inspection (or every 30 months,
whichever occurs ®rst). Engine Accessory Drive Belt
Inspection (or every 30 months, whichever occurs ®rst).
Cooling System Service (or every 30 months, whichever
occurs ®rst). Fuel Tank, Cap, and Lines Inspection.

Footnotes
²The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to
the completion of the vehicle's useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the
maintenance be recorded.
+A good time to check your brakes is during tire
rotation. See Brake System Inspection on page 6-29.
