6. Connect the red
positive
(+) cable to the
positive
(+) terminal
of the vehicle with the
dead battery.
7. Don’t let the other
end touch metal.
I
Connect it to the
positive
(+) terminal of
the good battery.
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
of the vehicle with
the dead battery.
9. Attach the cable at least
18 inches (45 cm) away
from the dead battery,
but
not near engine parts
that move.
The electrical
connection is just
as
good there, but the
chance
of sparks getting
back to the battery is
much less.

10. Now start the vehicle with the good battery and run
11. Try to start the vehicle with
the dead battery. If it
the engine for a while.
won’t start after a
few tries, it probably needs service.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t
touch
each other or any other metal.

Towing Your Vehicle
Try to have a GM dealer or a professional towing
service tow your vehicle. They can provide the right
equipment and know how to tow it without damage. See
“Roadside Assistance” in the Index.
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
things can be damaged during towing.
Before
you do anything, turn on the hazard
warning flashers.
When
you call, tell the towing service:
Whether your vehicle has rear-wheel drive or the
all-wheel-drive option.
That your vehicle cannot be towed from the front or
rear with sling-type equipment.
0 The make, model and year of your vehicle.
Whether you can still move the shift lever.
0 If there was an accident, what was damaged.

Your rear drum brakes don’t have wear indicators, but
if you ever hear a rear brake rubbing noise, have the
rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are
removed for rotation or changing. When you have the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase
in pedal
travel. This could be a sign
of brake trouble.
Brake Adjustment
Every time you make a brake stop, your disc brakes
adjust for wear.
If your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying
the brakes a few times.
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 vehicle 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 vehicle 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 replacement 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.
Bulb Replacement
Before replacing any bulbs, make sure all lamps are off
and the vehicle is not running. See “Replacement Bulbs”
in the Index.
Halogen Bulbs
Batteries have acid that can burn you and gas
that can explode. You can be badly hurt if you
aren’t careful. See “Jump Starting’’ in the Index
for tips on working around
a battery without
getting hurt.
Contact your dealer to learn how
to prepare your vehicle
for longer storage periods..
Also, for your audio system, see “Theft-Deterrent
Feature”
in the Index. Halogen bulbs have p’ surized gas
il de 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.
