Things that burn can get on hot engine parts and start a fire. These
include liquids like gasoline, oil, coolant, brake fluid, windsh\

washer and other fluids, and plastic or rubber. You or others could
be burned. Be careful not to drop or spill things that will burn onto a
hot engine.

prop from the slot in the hood and return the prop to its retainer. Then just

Engine Oil
It’s a good idea to check your engine oil every time you get fuel. In order to
get an accurate reading, the oil must be warm and the vehicle\
must be on level ground.

Oils with these words on the container will help you save fuel.
The doughnut-shaped logo (symbol) is used on most oil contain\
ers to
help you select the correct oil.
You should look for this on the oil container, and use
only those oils
that display the logo.
GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the \
requirements for your vehicle.
Engine Oil Additives: Don’t add anything to your oil. Your General
Motors dealer is ready to advise
if you think something should be added.
When to Change Engine Oil: See if any one of these is true for you:
Most trips are less than
4 miles (6 km).
It’s below freezing outside and most trips are less than 10 miles
(16 km).
The engine is at
low speed most of the time (as in door-to-door delivery,
or in stop-and-go traffic).
You
tow a trailer often.
Most trips are through dusty places.
If any one of these is true for your vehicle, then you need to change
your
oil and filter every 3,000 miles (5000 km) or 3 months-whichever
comes first.
If none of them is true, change the oil every 7,500 miles (12 500 km) or
12 months-whichever comes first. Change the filter at the first oil
change and at every other oil change after that.
Engine Block Heater: An engine block heater can be a big help if you have
to park outside in very cold weather,
0°F (-18°C) or colder. If your vehicle
has this option, see “Engine Block Heater” in the Index.

braking system-for example, when your brake linings wear down and you
have
to have new ones put in-be sure you get new genuine GM
replacement parts.
If you don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong for your vehicle, the
balance between your front and rear brakes can change, for the\
worse. The
braking performance you’ve come to expect can change in many\
other ways
if someone puts in the wrong replacement brake parts.
Hydro-Boost Brake System (Hydraulic Pump)
The power steering pump is also used as the Hydro-Boost pump. \
Refer to
“Power Steering Fluid” in this section when. checking the fluid level or adding
fluid.
Fluid Leak Check
After the vehicle has been parked for awhile, inspect the surf\
ace beneath the
vehicle for water, oil, fuel or other fluids. Water dripping f\
rom the air
conditioning system is normal. If you notice fuel leaks or fumes, the causes
should be found and corrected at once.

Other Maintenance Items
Front Suspension and Steering Linkage
The Maintenance Schedule will tell you how often to lubricate the fittings. See
“Recommended Fluids and Lubricants” in the Index for the proper lubricant to
use.
Front Wheel Bearings (Two-Wheel Drive)
If your vehicle is two-wheel drive, the front wheel bearings must \
be cleaned
and repacked at certain intervals. The Maintenance Schedule will tel\
l you how
often this must be done.
Single Belt Accessory Drive
Your new vehicle uses a serpentine belt that is lighter, more durable and fuel
efficient than systems 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

Lock Cylinders
To be sure your locks operate properly, they must be lubricated. \
The
Maintenance Schedule will tell you how often to lubricate them. See
“Recommended Fluids and Lubricants” in the Index for the \
proper lubricant to use.
You should not use penetrating oils because they could wash out th\
e 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.
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 emission control components.
Malfunction Indicator Lamp (SERVICE ENGINE SOON light)
The Malfunction Indicator Lamp (SERVICE ENGINE SOONlight) on y\
our 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.

Loading Your Vehicle
K3651
The Certificationrrire label is found on the rear edge of the driver’s door. The
label shows the size of your original tires and the inflation pressures needed
to obtain the gross vehicle weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
The Certificationflire label also tells you the maximum weights for the front
and rear axles, called Gross Axle Weight Rating (GAWR).
To find out the
actual loads on your front and rear axles, you need
to go to a weigh station
and weigh your vehicle. Your dealer can help you with this. Be sure
to
spread out your load equally on both sides of the centerline.
Never exceed the GVWR for your vehicle, or the Gross Axle Wei\
ght Rating
(GAWR) for either the front or rear axle.
And,
if you do have a heavy load, you should spread it out.
Do not load your vehicle any heavier than the GVWR or the
- maximum front and rear GAWRs. If you do, parts on your vehicle
can break, or
it can change the way your vehicle handles. These
could cause you
to lose control. Also, overloading can shorten the
life
of your vehicle. I

Finish Damage
Any stone chips, fractures or deep scratches in the finish should be repaired
right away. Bare metal will corrode quickly and may develop in\
to a major
repair expense.
Minor chips and scratches can be repaired with touch-up materia\
ls available
from your dealer
or other service outlets. Larger areas of finish damage can
be corrected in your dealer's body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow removal and dust control can \
collect on the
underbody.
If these are not removed, accelerated corrosion (rust) can occur \
on the underbody parts such as fuel lines, frame, floor pan, \
and exhaust
system even though they have corrosion protection.
At least every spring, flush these materials from the underbody\
with plain
water. Clean any areas where mud and other debris can collect.\
Dirt packed
in closed areas of the frame should be loosened before being flus\
hed. Your
dealer
or an underbody vehicle washing system can do this for you.
