Vehicle Storage
If you’re not going to drive you vehicle for 25 days or
more, remove the black, negative
(-) cable from
the battery. This will help keep your battery from
rl ling down.
Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to follow the
si s below to do it safely.
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” next 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 on page
3-98.
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or
They contain enough electricity to
ignite.
burn you.
If you don’t follow these steps exactly, some
or all of these things can hurt you.
5-46

Notice: Ignoring these steps could result in costly
damage to your vehicle that wouldn’t be covered
by your warranty.
Trying to start your vehicle by pushing or pulling
it
won’t work, and it could damage your vehicle.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.
Notice:
If the other system isn’t a 12-volt system
with a negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic
transaxle in PARK (P) or a manual transmission in
NEUTRAL (N) before setting the parking brake. Notice:
If you
leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or in the accessory power outlet. Turn
off
the radio and all lamps that aren’t needed. This will
avoid sparks and help save both batteries. And it
could save your radio!
4. Open the hood on the other vehicle and locate the
positive
(+) and the negative (-) terminal locations
on that vehicle.
Open the hood on your vehicle and find the remote
positive
(+) terminal located in the engine
compartment
on the passenger side of the vehicle.
See
Engine Compartment Overview on page 5-14
for more information on location.
5-47

You will not see the battery of your vehicle under
the hood.
It is located under the rear passenger’s
seat. You will not need to access the battery
for jump starting. The remote positive
(+) terminal
is for that purpose.
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. 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 ACDelco@
battery installed in your new 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.

r
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving parts once the engine
is running.
6. 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
basic things you should know. Positive
(+) will go to
positive
(+) or to a remote positive (+) terminal if
the vehicle has one. Negative (-) will go to a heavy,
unpainted metal engine part or to a remote
negative
(-) terminal if the vehicle has one.
Don’t connect positive
(+) to negative (-) or you’ll
get a short that would damage the batterv and
maybe other parts too. And don’t connect the
negative
(-) cable to the negative (-) terminal on
the dead battery because this can cause sparks.
7. Connect the red
positive
(+) cable to the
remote positive
(+)
terminal of the
dead battery. Use a
remote positive
(+)
terminal if the vehicle
has one.
8. Don’t !et 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.
5-49

9. Now connect the black
negative
(-) cable to
the negative (-)
terminal of the good
battery. Use a remote
negative
(-) terminal
if the vehicle has one.
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 engine part or
to a remote negative (-) terminal
on the vehicle with the dead battery.
10. Connect the other end
of the negative
(-)
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, and the
chance of sparks getting back
to the battery is much
less.
11.
12.
Now start the vehicle with the good battery and run
the engine for a while.
Try to start the vehicle that had the dead battery.
If it Won’t start after a few tries, it probably needs
service.

Notice: Damage to your vehicle may result from
electrical shorting
if jumper cables are removed
incorrectly. To prevent electrical shorting, take care
that the cables don’t touch each other or any
other metal. The repairs wouldn’t be covered by
your warranty.

Headlamp Aiming
Your vehicle has a visual optical headlamp aiming
system equipped with horizontal aim indicators. The aim
has been preset at the factory and should need no
further adjustment. This is true even though your
horizontal aim indicators may not fall exactly on
the
“0” (zero) marks on their scales.
If your vehicle is damaged in an accident, the headlamp
aim may be affected. Aim adjustment to the
low beam
may be necessary
if it is difficult to see lane markers
(for horizontal aim), or
if oncoming drivers flash
their high beams at you (for vertical aim).
If you believe
your headlamps need to be re-aimed, we recommend
that you take your vehicle to your dealer for service.
However, it is possible for you to re-aim your headlamps
as described in the following procedure.
Notice: To make sure your headlamps are aimed
properly, read all the instructions before beginning.
Failure
to follow these instructions could cause
damage to headlamp parts.
The vehicle should be properly prepared as follows:
The vehicle should be placed so the headlamps are
25 ft. (7.6 m) from a light colored wall or other flat
surface.
The vehicle must have all four tires on a perfectly
level surface which is level all the way to the wall
or other flat surface.
The vehicle should be placed so it is perpendicular
to the wall or other flat surface.
5-52

0 The vehicle should not have any snow, ice or mud
attached to it.
* The vehicle should be fully assembled and all other
work stopped while headlamp aiming is being done.
0 The vehicle should be normally loaded with a
full tank of fuel and one person or
160 Ibs. (75 kg)
on the driver’s seat.
Tires should be properly inflated.
Headlamp aiming is done with the vehicle low beam
lamps. The high beam lamps will be correctly aimed
if
the low beam lamps are aimed properly. The
headlamp aiming devices are under the hood near
the headlamps.
If you believe your headlamps need horizontal (lefthight)
adjustment, follow the horizontal aiming procedure.
If you believe your headlamps need only vertical
procedure.
