Bulb Replacement
See “Replacement Bulbs” in the Index to check the size
and type of bulb you need to use.
Halogen Bulbs
Halogen bulbs have pressurized gas inside and
can burst,if you drop or scratch the bulb. You or
others could
be injured. Be sure to read and
follow the instructions on the bulb package.
Headlamps
To replace the headlamp bulb:
1. Open the hood.
2. Push in on both sides of the electrical connector.
Then
pull up and rearward, to disconnect it from the
bulb. The plastic clip on the electrical connector may
need to be lifted gently with a screwdriver.

Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory
to give you the longest tire life
and best overall performance.
In most cases, you will not need to have your wheels
aligned again. However, if you notice unusual tire wear
or your vehicle pulling one way or the other, the
alignment may need
to be reset. If you notice your
vehicle vibrating when driving
on a smooth road, your
wheels may need
to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep corning loose, the wheel,
wheel bolts
and wheel nuts should be replaced. If the
wheel leaks
air, replace it (except some aluminum
wheels, which
can sometimes be repaired). See your
Geo dealer if any of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel
should have the same load-carrying
capacity, diameter, width, offset
and be mounted the
same way as
the one it replaces.
If you need to replace any of your wheels, wheel bolts
or wheel nuts, replace them only with new
GM original
equipment parts. This way, you will be sure to have the
right wheel, wheel bolts and wheel nuts for your
Geo model.
Using the wrong replacement wheels, wheel bolts
or wheel nuts on your vehicle can be dangerous. It
could affect the braking and handling of your
vehicle, make your tires lose air and make
you lose
control.
You could have a collision in which you or
others could be injured. Always use the correct
wheel, wheel bolts and wheel nuts for replacement.
NOTICE:
The wrong wheel can also cause problems with
bearing life, brake cooling, speedometer or
odometer calibration, headlamp aim, bumper
height, vehicle
ground clearance and tire or tire
chain clearance to the body and
chassis.

Your vehicle has an air bag system. Before attempting to
add anything electrical to your
Geo, see “Servicing Your
Air Bag-Equipped Geo” in the Index.
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.
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. 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.
Before replacing
a fuse, turn every vehicle electrical
switch
off.
There are two fuse blocks in your vehicle: the
instrument panel fuse block and the engine compartment
fuse block.
Instrument Panel Fuse Block
This 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.

Main Fuse Block
The main fuse box in your engine compartment protects
all electrical loads.
For access
to the main fuses, pull off the cover. A spare
fuse is
also inside the fuse box.
