Trunk Lid
I
It can be dangerous to drive with the trunk lid
open because carbon monoxide
(CO) gas can
come into your vehicle. You can’t see or smell
CO. It can cause unconsciousness and even death.
If you must drive with the trunk lid open or if
electrical wiring or other cable connections must
pass through the
seal between the body and the
trunk lid:
Make sure all windows are shut.
Turn the fan on your heating or cooling
system to its highest speed with the setting
on ECON or VENT. That will force outside
air into your vehicle. See “Comfort
Controls”
in the Index.
If you have air outlets on or under the
instrument panel, open them
all the way.
See “Engine Exhaust” in the Index.

Theft
Vehicle theft is big business, especially in some cities.
Although your vehicle has a number of theft-deterrent
features, we know that nothing we put
on it can make
it impossible to steal. However, there are ways you
can help.
Key in the Ignition
If you leave your vehicle with the keys inside, it’s an
easy target for joy riders or professional thieves -- so
don’t do it.
With the ignition
off and the driver’s door open, you’ll
hear a tone reminding you to remove your key from the
ignition and take it with you. Always do this. Your
steering wheel will be locked, and
so will your ignition
and transaxle. And remember to lock
the doors.
Parking at Night
Park in a lighted spot, close all windows and lock your
vehicle. Remember to keep your valuables out of sight.
Put them in a storage area, or take them with you.

Safety Belt Reminder Light
When the key is turned to RUN or START, a chime will
come on for about eight seconds to remind people to
fasten their safety belts.
The safety belt light
will
also come on and stay on
for about
70 seconds. If the
driver’s belt is already
buckled, neither the chime nor the light will come
on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows
AIR BAG. The system checks the
air bag’s electrical system for malfunctions. The light
tells you if there
is an electrical problem. The system
check includes
the air bag sensors, the air bag modules,
the wiring and the crash sensing and diagnostic module.
For more information on
the air bag system, see “Air
Bag” in the Index.
BAG 4
AIR a*
This light will come on
when you start your engine,
and it will flash
for a few
seconds. Then the light
should go
out. This means
the system is ready.
If the air bag readiness light stays on after you start the
engine or comes on when you are driving, your
air bag
system may not work properly. Have your vehicle
serviced right away.
The
air bag readiness light should flash for a few
seconds when you
turn the ignition key to RUN. If the
light doesn’t come on then, have it fixed
so it will be
ready to
warn you if there is a problem.

Tbrn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Pontiac dealer. The green arrows on your
instrument panel will flash whenever
you signal a turn
or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about to turn,
change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs
on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Your vehicle has bulb warning lights. When you plug a
trailer lighting system into your vehicle’s lighting
system, its bulb warning lights may not let you know
if
one of your lamps goes out. So, when you have a trailer
lighting system plugged in, be sure to check your
vehicle and trailer lamps from time to time to be sure
they’re all working. Once you disconnect the trailer
lamps, the bulb warning lights again can tell
you if one
of your vehicle lamps is out.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long or steep downgrade.
If you don’t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if
you ever have to park your rig on a hill, here’s
how to do it:
1.
2.
3.
4.
5.
Apply your regular brakes, but don’t shift into
PARK (P) yet.
Have someone place chocks under the trailer wheels.
When the wheel chocks are in place, release the
regular brakes until
the chocks absorb the load.
Reapply the regular brakes. Then apply your parking
brake, and then shift to PARK (P).
Release the regular brakes.

3. Remove the five nuts that hold the assembly in place
with a
10 mm socket. Pull the carpet up and out of
the way to remove the center nut. (There are two
nuts
on the driver's side, two on the passenger's side
and one in
the middle.)
4. Lift up on both plastic side flaps at the same time
(driver's side shown) and lift
the assembly out.
5. Carefully let go of the decklid and let it raise
completely. The assembly will still be connected to
the wiring harness, but now you will have access to
the bulbs.

Electrical System
Add-on Electrical Equipment
NOTICE:
Don’t add anything electrical to your vehicle
unless you check with your dealer first. Some electrical equipment can damage your vehicle
and the damage wouldn’t be covered by your
warranty. Some add-on electrical equipment
can keep other components
from working as
they should.
Your vehicle has an air bag system. Before attempting to
add anything electrical
to your vehicle, see “Servicing
Your Air Bag-Equipped Vehicle” in the Index.
Headlamp Wiring
The headlamp wiring is protected by an internal
circuit breaker. An electrical overload will cause
the
lamps to go on and off, or in some cases to remain off.
If this happens, have your headlamp system checked
right away.
Windshield Wipers
The windshield wiper motor is protected by an internal
circuit breaker
and a fuse. If the motor overheats due to
heavy
snow, etc., the wiper will stop until the motor
cools.
If the overload is caused by some electrical
problem, be sure
to have it fixed.
Power Windows and Other Power Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When
the
current load is too heavy, the circuit breaker opens and
closes, protecting the circuit until the problem is fixed
or goes away.

Maxifuse@/Relay Center
To check the fuses in this underhood fuse center,
turn the two
knobs one-quarter turn to the left
(counterclockwise) and loosen the metal wing
nut on
the passenger side of the cover. Then remove the cover.
The inside of the cover has
a chart that explains the
features and controls governed
by each fuse and relay.
Fuses and Circuit Breakers
The wiring circuits in your vehicle are protected from
short circuits by a combination of fuses, circuit breakers
and fusible thermal links. This greatly reduces the
chance
of damage 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 identical size
and rating.
If you ever have a problem on the road and don't have
a spare fuse,
you can borrow one that has the same
amperage. 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 correct amperage.
Replace
it as soon as you can.
There
are two fuse blocks in your vehicle: the driver's
side and passenger's side fuse blocks.
