Engine Exhaust
CAUTION:
Engine exhaust can kill. It contains the gas
carbon monoxide (CO), which you can't see or
smell. It can cause unconsciousness and death.
You might have exhaust coming in if:

Your exhaust system sounds strange
or different.

Your vehicle gets rusty underneath.

Your vehicle was damaged in a collision.

Your vehicle was damaged when driving over
high points on the road or over road debris.

Repairs weren't done correctly.

Your vehicle or exhaust system had been
modified improperly.
If you ever suspect exhaust is coming into
your vehicle:

Drive it only with all the windows down to
blow out any CO; and

Have your vehicle fixed immediately.
Running Your Engine While
You're Parked
It's better not to park with the engine running. But if you
ever have to, here are some things to know.
CAUTION:
Idling the engine with the climate control
system off could allow dangerous exhaust into
your vehicle. See the earlier Caution under
ªEngine Exhaust.º
Also, idling in a closed-in place can let deadly
carbon monoxide (CO) into your vehicle even
if the fan 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 ªBlizzardº in the Index.

2-39
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 ªShifting Into PARK (P)º in the Index.
If you are parking on a hill and if you're pulling a
trailer, also see ªTowing a Trailerº in the Index.

Press the horn symbols on your steering wheel pad to
sound the horn.
Tilt Wheel
A tilt wheel allows you to adjust the steering wheel
before you drive. You can raise it to the highest level
to give your legs more room when you exit and enter
the vehicle.
The lever that allows you to tilt the steering wheel is
located on the left side of the steering column.
To tilt the wheel, hold the
wheel and pull the lever.
Then move the steering
wheel to a comfortable
position and release the
lever to lock the wheel
into place.

two chimes signal that the perimeter lighting feature is
enabled. Each additional press will advance the mode by
one, starting from the current mode. During this
procedure, the feature will sound the number of chimes
corresponding to the mode. When the lock switch is
released, the vehicle will remain in the last mode.
Disconnecting the vehicle's battery for up to a year will
not change the programmed operation for this feature.Rearview Mirror Reading Lamps

Battery Rundown Protection
Your vehicle has a feature to help prevent you from
draining the battery in case you accidentally leave
the interior courtesy lamps, reading/map lamps, visor
vanity lamps, trunk lamp, underhood lamp or glove box
lamps on. If you leave any of these lamps on, they will
automatically turn off after 20 minutes, if the ignition is
in OFF. The lamps won't come back on again until you
do one of the following:

Turn the ignition on,

turn the exterior lamps control off, then on, or

open a door.
If your vehicle has less than 15 miles (25 km) on the
odometer, the battery saver will turn off the lamps after
only three minutes.

2-62 OnStar Services
The following services are available within OnStar
service plans. Your vehicle comes with a specific
one
-year service plan that allows use of some or
all for the following services.

2-67 Speedometer and Odometer
The speedometer lets you see your speed in both miles
per hour (mph) and kilometers per hour (km/h). The
odometer shows how far your vehicle has been driven in
either miles (used in the United States) or in kilometers
(used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
You may wonder what happens if your vehicle needs a
new odometer installed. If the new one can be set to the
mileage total of the old odometer, then that will be done.
But if it can't, then it will be set at zero and a label must
be put on the driver's door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer tells how far you have driven since
you last reset it. To set it to zero, press the button on
the right side of the instrument panel cluster.
The trip/select reset button will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds.If the button is pressed and held for longer than
1.5 seconds while in the trip odometer mode, it will be
reset to zero. If the button is pressed and held for longer
than 1.5 seconds while in the odometer mode, it will
have no effect.
Tachometer (Option)
The tachometer displays the
engine speed in thousands
of revolutions per minute
(rpm). (Optional cluster
tachometer shown.)
NOTICE:
Do not operate the engine with the tachometer
in the red area, or engine damage may occur.

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 section, you should not be alarmed
when this happens.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
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.
Your vehicle may also have a driver information center
that works along with the warning lights and gages.
See ªDriver Information Centerº in the Index.
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.

2-71
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 ªTowing Your Vehicleº in
the Index.
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
United States Canada
The anti
-lock brake system warning light should come
on for a few seconds when you turn the ignition key to
RUN. If the anti
-lock brake system warning light stays
on longer than normal after you've started your engine,
turn the ignition off. Or, if the light comes on and stays
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, the anti
-lock brake system needs
service and you don't have anti
-lock brakes.
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.

2-72 Traction Control System Warning Light
The traction control
system warning light
may come on for the
following reasons:

If you turn the system off by pressing the traction
control button located on the black panel directly
behind your automatic transaxle 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 ªTraction Control Systemº in
the Index for more information.

With Full
-Range Traction Control equipped
vehicles, if there's a brake system problem that is
specifically related to traction control, the traction
control system will turn off and the warning light
will come on. If your brakes begin to overheat, the
traction control system will turn off and the warning
light will come on until your brakes cool down.
If the traction control system is affected by an
engine
-related problem, the system will turn off
and the warning light will come on.

With Full
-Range Traction Control, if there is a base
brake problem, the system will turn off and the light
will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Low Traction Light
This light will come
on when the traction
control system is
limiting wheel spin.
You may feel or hear the system working, but this
is normal. Slippery road conditions may exist if the
low traction light comes on, so adjust your driving
accordingly. The light will stay on for a few seconds
after the traction control system stops limiting wheel
spin. See ªTraction Control Systemº or ªFull
-Range
Traction Control Systemº in the Index.
