When you go to your GM dealer/
retailer and ask for GM Accessories,
you will know that GM-trained and
supported service technicians will
perform the work using genuine GM
Accessories.

Doing Your Own
Service Work
{CAUTION
You can be injured and the
vehicle could be damaged if you
try to do service work on a vehicle
without knowing enough about it.
•Be sure you have sufficient
knowledge, experience, the
proper replacement parts, and
tools before attempting any
vehicle maintenance task.
(Continued)
CAUTION (Continued)
•Be sure to use the proper
nuts, bolts, and other
fasteners. English and
metric fasteners can be
easily confused. If the wrong
fasteners are used, parts
can later break or fall off.
You could be hurt.
If doing some of your own service
work, use the proper service
manual. It tells you much more
about how to service the vehicle
than this manual can. To order
the proper service manual,
see Service Publications Ordering

Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel fill.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.
The engine oil dipstick handle
is a yellow loop. See Engine
Compartment Overview on page 9-6
for the location of the engine oil
dipstick.
1. Turn off the engine and give the oil several minutes to drain back
into the oil pan. If this is not done,
the oil dipstick might not show the
actual level.
2. Pull out the dipstick and clean it with a paper towel or cloth,
then push it back in all the way.
Remove it again, keeping the tip
down, and check the level.

Electrical System
Electrical System
Overload
The vehicle has fuses and circuit
breakers to protect against an
electrical system overload.
When the current electrical load is
too heavy, the circuit breaker opens
and closes, protecting the circuit until
the until the current load returns to
normal or the problem is fixed. This
greatly reduces the chance of circuit
overload and fire caused by electrical
problems. Fuses and circuit breakers protect
the following in the vehicle:
•Headlamp Wiring
•Windshield Wiper Motor
•Power Windows and other Power
Accessories
Headlamp Wiring
An electrical overload may cause
the lamps to go on and off, or in
some cases to remain off. Have
the headlamp wiring checked right
away if the lamps go on and off or
remain off.
Vehicle Care 9-37
Page 222 of 318

Windshield Wipers
If the wiper motor overheats due to
heavy snow or ice, the windshield
wipers will stop until the motor cools
and will then restart.
Although the circuit is protected from
electrical overload, overload due to
heavy snow or ice, may cause wiper
linkage damage. Always clear ice
and heavy snow from the windshield
before using the windshield wipers.
If the overload is caused by an
electrical problem and not snow
or ice, be sure to get it fixed.
Fuses and Circuit
Breakers
The wiring circuits in the vehicle are
protected from short circuits by a
combination of fuses, circuit breakers
and fusible thermal links. This greatly
reduces the chance of fires caused
by electrical problems.
Look at the silver-colored band
inside the fuse. If the band is broken
or melted, replace the fuse. Be sure
you replace a bad fuse with a new
one of the identical size and rating.
Fuses of the same amperage can be
temporarily borrowed from another
fuse location, if a fuse goes out.
Replace the fuse as soon as
you can.
Engine Compartment
Fuse Block
This engine compartment fuse block
is located in the engine compartment
on the driver side of the vehicle
near the air cleaner. SeeEngine
Compartment Overview on page 9-6 .
Notice: Spilling liquid on any
electrical components on the
vehicle may damage it. Always
keep the covers on any electrical
component.
