Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by fuses, circuit breakers and thermal links
in the wiring itself. This greatly reduces the chance of
fires caused by electrical problems.
The main fuse box in your engine compartment is on the
right side. It protects all electrical loads.
For access to the main fuses, pull off
the cover. A spare
fuse
is also inside the fuse box. Another
fuse box is under the left
side of the instrument
panel.
The fuses here protect each separate circuit
including headlamps. If you have electrical failure,
check here first.

Air Conditioning Refrigerants
Not all air conditioning refrigerants are the same. If the air
conditioning system
in your vehicle needs refrigerant, be
sure the proper refrigerant is used. If you’re not sure, ask
your Chevrolet/Geo dealer.

Gem Section 7 Maintenance Schedule
IMPORTANT:
KEEP ENGINE OIL
AT THE PROPER
RECOMMENDED
This section covers the maintenance required for your
Geo. Your vehicle needs these services to retain
its
safety, dependability and emission control performance.
Introduction
Your Vehicle and the Environment
Proper vehicle maintenance not only helps to keep your
vehicle
in good working condition, but also helps the
environment. All recommended maintenance procedures
are important. Improper vehicle maintenance or the
removal
of important components can significantly
affect the quality of the
air we breathe. Improper fluid
levels or even the wrong tire inflation can increase the
level of emissions from your vehicle.
To help protect our
environment, and to help keep your vehicle in good
condition, please maintain your vehicle properly.
Have you purchased the GM Protection Plan .? The Plan
supplements your new vehicle warranties. See your
Chevrolet/Geo dealersfor details.
