Downloaded from www.Manualslib.com manuals search engine Fuses and Circuit
Breakers
The wiring circuits in your vehicle are
protected from short circuits by a
combination of maxi-fuses, mini-fuses
and circuit breakers. This greatly reduces
the chance of fires caused by electrical
problems.
There are three fuse centers on your
vehicle. One
is in the right side of your
instrument panel. Turn the knob and pull
the door to access the fuses. The other
two fuse blocks are in the
engine compartment. One is part of the
Forward Lamp wiring harness
(A), and
the other is part of the ECM-Engine
wiring harness
(B).
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 correct
size.
If you ever have a problem on the road
and don’t have a spare fuse, you can
borrow one of the correct value. Just pick
some feature of your vehicle that you can
get along without
- like the radio or
cigarette lighter
- and use its fuse, if it
is the size you need. Replace it as soon
as you can.
Headlights
The headlight wiring is protected by a
circuit breaker
in the switch. An electrical
overload will cause the lights to go on and
off, or in some cases to remain
off. If this
happens, have your headlight wiring
checked right away.
Windshield Wipers
The windshield wiper motor is protected
by a circuit breaker and a fuse. If the
motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If the overload is caused by some
electrical problem and not snow, etc.,
be sure to get
it fixed.
Power Windows and Other Power
Options
Circuit breakers protect the power
windows and other power accessories.
When the current load is too heavy,
the circuit breaker opens and closes,
protecting the circuit until the problem
is fixed or goes away.

Explanation of Scheduled
Maintenance Services
Following are explanations of the services
listed in Schedule I and Schedule
11.
The proper fluids and lubricants to use are
listed in Section D. Make sure whoever
services your vehicle uses these. All parts
should be replaced and all necessary
repairs done before you or anyone else
drives the vehicle.
NOTE: To determine your engine’s
displacement and code, see
“Engine Identification” in the
Index.
ITEM
NO. SERVICE
1 Engine Oil and Filter Change* -
Always use SH or SG Energy
Conserving I1 oils of proper
viscosity. The engine requires a
special oil meeting GM Standard
GM4718M. Oils meeting this
Standard may be identified as
synthetic, and should also be
identified as API Service
SH or
SG. However, not all Synthetic
API Service
SH oils will meet

NO. SERVICE
this GM Standard. You should
look for and use only an oil that
meets GM Standard GM4718M.
To determine the preferred
viscosity for your vehicle’s
engine (e.g.,
SAE 5W-30 or SAE
10W-30), see “Engine Oil” in
the Index.
Your vehicle has an Engine Oil
Life Monitor. This monitor will
show you when to change the oil
- usually between 3,000 miles
(5 000 km) and 7,500 miles
( 12 500 km) since your last oil
change. Under severe conditions
the indicator may come on before
3,000 miles
(5 000 km). Never
drive your vehicle more than
7,500 miles (12
500 km) or 12
months without an oil change.
The system won’t detect dust in
the oil..
So if you drive in a dusty
area be sure
to change your oil
every 3,000 miles
(5 000 km) or
sooner if the “Change Oil” light
comes on.

SERVICE
Remember to reset the Oil Life
Monitor when the oil has been
changed. For more information, see “Engine Oil Life Monitor”
in the Index.
Chassis Lubrication
- Lubricate
suspension and steering linkage.
Lubricate the transmission shift
linkage, and parking brake cable guides, underbody contact points
and linkage.
Engine Accessory Drive Belt(s) Inspection
- Inspect the belt(s)
for cracks, fraying, wear and
proper tension. Replace as needed. (Belts can have many
small cracks in individual ribs
without affecting performance.)
Cooling System Service*
-
Drain, flush and refill the system with
new or approved recycled
coolant conforming to GM
Specification 1825M. Keep
coolant at the proper mixture as
specified. See “Coolant” in the
* An Emission Control Service.
