Running Your Engine While You’re
Parked (Automatic Transaxle)
It’s better not to park with the engine running. But if you
:ver have to, here are some things
to know.
h
A CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into your vehicle
(see the earlier Caution under “Engine Exhaust”),
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is
a garage. Exhaust -- with
CO
-- can come in easily. NEVER park in a
garage
with the engine running.
Another closed-in place can be a blizzard, (See
“Blizzard” in the Index.)
I
A CAUTION:
It can be dangerous to get out of your vehicle if
the shift lever is not fully in PARK (P) with the
parking brake firmly set. Your vehicle can roll.
Don’t leave your vehicle when the engine is
running unless you have to.
If you’ve left the
engine running, the vehicle can move suddenly.
You or others could be injured. To be sure your
vehicle won’t move, even when you’re on fairly
level ground, always set your parking brake and
move the shift lever to PARK (P).
Follow the proper steps to be sure your vehicle won’t
move. See “Shifting Into
PARK (P)” in the Index.
If you are parking on a hill and if you’re pulling a
trailer, also see “Towing a Trailer” in the Index.

Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front
of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.
The DRL system will make your high-beam headlamps
come on at a reduced brightness when:
The engine is running,
0 The headlamp switch is in the OFF position,
The light sensor detects daytime light,
0 The parking brake is released and
The shift lever is not in PARK (P) on an
automatic transaxle.
When the DRL system is on, the taillamps, sidemarker,
park lamps
and instrument panel lights will not be
illuminated.
The DRL and the ALC systems will remain off any time
your automatic transaxle vehicle is in PARK (P) and the
parking brake is engaged.
The DRL and the ALC systems will remain
off any time
your manual transaxle vehicle is in NEUTRAL (N) and
the parking brake is engaged.
Automatic Light Control (ALC)
Your vehicle is equipped with an automatic light sensor
on top of the instrument panel under the defroster grill,
so be sure it is not covered which will cause the
nighttime lights to be on continuously.
When it is dark enough outside, your ALC will turn
on
your low-beam headlamps at the normal brightness
along with other lamps such as the taillamps,
sidemarker, park lamps and instrument panel lights.
There is a 20-second delay in the transition between
daytime and nighttime operation
of the DRL and the
ALC systems.
If the light sensor senses a reduction in
lighting that lasts longer than
20 seconds, it will activate
the nighttime lamps. If you are driving through a
parking garage, heavy overcast weather, a tunnel or
fueling your vehicle in a low light area, the ALC will
turn on your low-beam headlamps at a normal
brightness along with the taillamps, sidemarker, park
lamps and the instrument panel lights. The radio lights
will be dimmer.
As with any vehicle, you should turn on the regular
headlamp system when you need
it.

Tachometer
The tachometer shows your
engine speed in revolutions
per minute (rpm).
Warning Lights, Gages and Indicators
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
your warning lights and gages could also save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions.
As you will
see
in the details on the next few pages, some warning
lights come on briefly when you start the engine just to let \
you know they’re working. If you are familiar with this
NOTICE: section, you should not be alarmed when this happens.
Gages can indicate when there may be
or is a problem
Do not run your engine at speeds in the red area,
warning lights work together to let you know when or engine damage may occur.
with one of your vehicle’s functions. Often gages and
there’s a problem with your vehicle. When one
of the warning lights comes on and stays on
when
you are driving, or when one of the gages shows
there may be a problem, check the section that tells you what to
do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
-- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.

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, unless the driver’s safety belt is
already buckled,
The safety belt light will also come on and stay
on for about
20 seconds,
then it will flash for about
55 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 sensor, 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.
AIR
BAG
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.
2-59

Charging System Indicator Light
The charging system
indicator light will come on
briefly when you turn on the ignition, but the engine is
not running. The light will
go out when the engine
is stated.
If it stays on when your engine is running, or comes on
while you are driving, you may have a problem with the
electrical charging system.
It could indicate that you
have a loose generator drive belt or another electrical
problem. Have it checked right away. Driving while this
light is
on could drain your battery.
If you must drive a short distance with the light on, be
certain to turn
off all your accessories, such as the radio
and air conditioner.
Brake System Warning Light
Your Pontiac’s hydraulic brake system is divided into
two parts.
If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If the warning light comes on, there could be a brake
problem or the brake fluid level could be low. Have your
brake system inspected right away.
BRAKE
United States Canada
This light should come on briefly when you turn the
ignition key to RUN. If it doesn’t come on then, have it
fixed
so it will be ready to warn you if there’s a problem.
2-60

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop.
If the light is still on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
A CAUTION:
Your brake system may not be working properly
if the brake system warning light is
on. Driving
with the brake system warning light on can lead
to an accident. If the light is still on after you’ve
pulled off the road and stopped carefully, have
the vehicle towed for service.
When the ignition is on, the brake system warning light
will also come on when you set your parking brake. The
light will stay on
if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Anti-Lock Brake System Warning Light
With the anti-lock brake
system, this light will come
on when you start your
engine and it will stay
on for three seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re driving, stop as soon as
possible and turn the ignition off. Then start the engine
again to reset the system. If the light still stays on, or
comes on again while you’re driving, your Pontiac
needs service.
If the regular brake system warning light
isn’t on, you still have brakes, but you don’t have
anti-lock brakes.
If the regular brake system warning
light is also on, you don’t have anti-lock brakes and
there’s a problem with your regular brakes. See “Brake
System Warning Light” earlier in this section.
The anti-lock brake system warning light should come on briefly 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.
2-61

Enhanced Traction System Warning Light
(If Equipped)
ETS
OFF
With the Enhanced Traction
System (ETS), this warning
light should come on briefly as you start the engine. If
the warning light doesn’t come on then, have
it fixed
so it will be ready to warn
you if there’s a problem.
If it stays on, or comes on when you’re driving, there
may be a problem with your Enhanced Traction System
and your vehicle may need service. When this warning
light is on, the system will not limit wheel spin. Adjust
your driving accordingly. The Enhanced
Traction System warning light may come
on for the following reasons:
If you turn the system off by pressing the button on
the shift lever, the warning light will come on and
stay on.
To turn the system back on, press the button
again. The warning light should go
off. (See
“Enhanced Traction System” in the Index for
more information.)
The warning light will come on when you set your
parking brake with the engine running, and
it will
stay on if your parking brake doesn’t release fully.
If the system is turned on and the warning light stays
on after your parking brake is fully released,
it
means there’s a problem with the system.
If the Enhanced Traction System warning light comes
on and stays on for an extended period of time when the
system is turned on and the parking brake is fully
released, your vehicle needs service.
2-62

Enhanced Traction System Active Light
(If Equipped)
LOW
TRAC
When your Enhanced
Traction System is limiting
wheel spin, this light will
come on. Slippery road
conditions may exist if
the Enhanced Traction
System active light
comes on,
so adjust your
driving accordingly.
The light will stay on for a
few seconds after the
Enhanced Traction System stops limiting wheel spin.
The Enhanced Traction System active light also comes
on briefly when you turn the ignition key to RUN, If the
light doesn’t come on then, have it fixed
so it will be
there to tell you when the system is active.
Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the
gage pointer moves into
the red area, your engine
is too hot!
A light will come on to the right of the gage when the
gage pointer moves beyond the normal operating zone.
It means that your engine coolant has overheated.
If you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn off the engine as soon as possible.
In “Problems on the Road,” this manual shows what to
do. See “Engine Overheating” in the Index.
2-63

Low Coolant Warning Light
If this light comes on and
stays on, the vehicle should
be promptly pulled off the
road and the coolant level
checked. See “Engine
Coolant” in the Index.
If there are visible signs of steam see “Engine
Overheating” in the Index before opening the hood.
Malfunction Indicator Lamp
(Check Engine Light)
Your Pontiac is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
CHECK
ENGINE
This system is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the life
of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD
I1 is replaced by
Enhanced Diagnostics.) The CHECK
ENGINE light
comes on
to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent. This may
prevent more serious damage to your vehicle.
This
system is also designed to assist your service technician
in correctly diagnosing
any malfunction.
2-64

NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead
to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come on during a malfunction in one
of
two ways:
0 Light Flashing -- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
0 Reducing vehicle speed.
0 Avoiding hard accelerations.
0 Avoiding steep uphill grades.
0 If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady, see “If
the Light
Is On Steady” following.
If the light continues to flash, when it is safe to do
so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least 10 seconds and restart the
engine.
If the light remains on steady, see “If the Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
