vehicles. Turn
off all lights that
aren’t needed, and radios. This will
avoid sparks and help save both
batteries. And
it could save your

A An electric fan can start up
- even when the engine is not
running and
can injure you. Keep
hands, clothing and tools away from any underhood electric fan.
Find the positive
(+) and negative
(-) terminals on each battery. Using
a match near
a battery
can cause battery gas to
explode. People
have been hurt
doing this, and some have been
blinded. Use a flashlight if
you
need more light.
Be sure the battery has enough
water. You don’t need to add
water to the Delco Freedom*
battery installed
in every new GM
vehicle. But if a battery has filler
caps, be sure the right amount of
fluid is there. If it is low, add
water
to take care of that first. If
you don’t, explosive gas could be
present.
Battery fluid contains acid that can
burn you. Don’t get
it on you. If
you accidentally get
it in your eyes
or on your skin, flush the place
with water and get medical help
immediately.

5. Check that the jumper cables don’t
have loose or missing insulation.
If
they do, you could get a shock. The
vehicles could be damaged, too.
Before you connect
the cables, here
are some things you should
know.
Positive (+) will go to positive (+)
and negative (-) will go to negative
(-) or a metal engine part. Don’t
connect
(+) to (-) or you’ll get a
short that would damage the battery
and maybe other parts, too.
Fans or other moving engine
parts can injure you badly.
-eep your hands away from
moving parts once the engines are
running.
6. Connect the red positive (+) cable to
the positive
(+) terminal of the
vehicle with the dead battery. Use a
remote positive
(+) terminal if the
vehicle has one.

7. Don’t let the other end touch metal.
Connect
it to the positive (+)
terminal of the good battery. Use a
remote positive
(+) terminal if the
vehicle has one.
8. Now connect the black negative (-)
cable to the good battery’s negative
( -) terminal.
Don’t let the other end touch
anything
until the next step. The
other end
of the negative cable
doesn’t go to the dead battery. It
goes
to a heavy unpainted metal
part on the engine
of the vehicle

(45 cm) away from the dead
battery, but not near engine parts

connection is just as good there, but
the chance
of sparks getting back to
the battery
is much less.

Towing Your Vehicle
Try to have a GM dealer or a
professional towing service tow your
Geo. The usual towing equipment is
a
sling-type (A) or a wheel-lift (B) or car
carrier
(C) tow truck.
If your vehicle has been changed or
modified since it was factory-new by
adding aftermarket items like fog lamps,
aero skirting, or special tires and
wheels, these instructions and
illustrations may not be correct.
Before you
do anything, turn on the
hazard warning flashers.
When you call, tell the towing service:
A dolly must be used when towing
from the front.

Replacing Brake System Parts
The braking system on a modern vehicle
is complex. Its many parts have to be of
top quality and work well together if the
vehicle is to have really good braking.
Vehicles we design and test have
top-quality
GM brake parts in them, as
your Geo does when it is new. When
you replace parts of your braking system
- for example, when your brake linings
wear down and you have to have new
ones put in
- be sure you get new
genuine GM replacement parts. If you
don’t, your brakes may
no longer work
properly. For example, if someone puts
in brake linings that are wrong for your
vehicle, the balance between your front
and rear brakes can change,
for the
worse. The braking performance you’ve
come to expect can change in many
other ways if someone puts in the wrong
replacement brake parts.
Battery
Every new Geo has a Delco Freedom@
battery.
You never have to add water to
one of these. When it’s time for a new
battery, we recommend a Delco
Freedom@ battery. Get one that has the
catalog number shown on the original
battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle
for
25 days or more, take off the black,
negative
(-) cable from the battery.
This will help keep your battery from
running down.
