Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need
a well-charged battery to
restart the vehicle, and possibly for signaling later
on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you feel really uncomfortable
from the cold. But do it
as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour or
so until help comes.

Bulb Replacement
See “Replacement Bulbs” in the Index to check the size
and type
of bulb you need to use.
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 Replacement
Replace any wheel that is bent, cracked, or badly rusted
or corroded.
If wheel nuts keep coming 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
Chevrolet/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. I NOTICE:
The wrong wheel can also cause problems
with bearing life, brake cooling,
speedometer/odometer calibration, headlamp aim, bumper height, vehicle ground clearance,
and tire or tire chain clearance to the body and
chassis.

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.
