If the air bag readiness light stays on after you start the
vehicle or comes on when you are driving, your air
bag system may not work properly. Have your vehicle
serviced right away.
{CAUTION:
If the air bag readiness light stays on after you
start your vehicle, it means the air bag system
may not be working properly. The air bags in
your vehicle may not in¯ate in a crash, or they
could even in¯ate without a crash. To help
avoid injury to yourself or others, have your
vehicle serviced right away if the air bag
readiness light stays on after you start your
vehicle.
The air bag readiness light should ¯ash for a few
seconds when you turn the ignition key to RUN. If the
light doesn't come on then, have it ®xed so it will
be ready to warn you if there is a problem.
Charging System Light
The charging system light
will come on brie¯y when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have a
problem with the charging system. It could indicate
that you have problems with a 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.

Voltmeter Gage
When your engine is not
running, but the ignition is
on (in RUN), this gage
shows your battery's state
of charge in DC volts.
When the engine is running, the gage shows the
condition of the charging system. Readings between the
low and high warning zones indicate the normal
operating range.
Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine is left idling for an
extended period. This condition is normal since the
charging system is not able to provide full power
at engine idle. As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.You can only drive for a short time with the reading in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
When the ignition is on, the brake system warning light
will 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. A chime
may also sound when the light comes on.
Your vehicle'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.

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, mis®ring, hesitation
on acceleration or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to ®x any
mechanical or electrical problems that may have
developed.
Emissions Inspection and Maintenance
Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this
inspection could prevent you from getting a vehicle
registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

Compact Disc Messages
CHECK CD:If this message appears on the radio
display, it could be due to one of the following reasons:
·You're driving on a very rough road. When the
road becomes smoother, the disc should play.
·The disc is dirty, scratched, wet or upside down.
·The air is very humid. If so, wait about an hour and
try again.
·There may have been a problem while burning
the CD.
·The label may be caught in the CD player.
If the CD is not playing correctly, for any other reason,
try a known good CD.
If any error occurs repeatedly or if an error can't be
corrected, contact your dealer. If your radio displays an
error message, write it down and provide it to your
dealer when reporting the problem.
Rear Seat Entertainment System
Your vehicle may have the optional Digital Versatile Disc
(DVD) entertainment system. The entertainment
system includes a DVD player, a video display screen,
two sets of IR (Infrared) wireless headphones, a
remote control and an instructional video disc.
Before You Drive
The video entertainment system is for passengers in the
second and third row seats only. The driver cannot
safely view the video screen while driving and should
not try to do so.
In severe or extreme temperature conditions your
entertainment system should not be operated until the
temperature is within the operating range. This will keep
your video components from being damaged when
the temperature is below-4ÉF (-20ÉC) or above
140ÉF (60ÉC). To resume operation, shut off the
entertainment system, pull down the video screen and
then heat or cool the vehicle until the temperature
is within the operating range.
Headphones
The entertainment system includes two IR wireless
headphones.
Mini-headphone jacks are also provided for use with
customer provided headphones.
The wireless headphones have an ON/OFF switch and
a volume control. To use the headphones turn the
switch to ON. An indicator light will illuminate. If the light
does not illuminate, the batteries may need to be
replaced. See
Battery Replacementlater in this section
for more information. Switch the headphones to OFF
when not in use.

If the system is shut off, or if the headphones are out of
range of the IR transmitters below the overhead RSE
control panel for more than three minutes, the
headphones will shut off automatically to save the
batteries. If you move too far forward or step out of the
vehicle, the headphones will cut out.
To adjust the volume on the headphones, use the
volume control.
Notice:Do not store the headphones in heat or
direct sunlight. This could damage the headphones
and repairs would not be covered by your warranty.
Keep the headphones stored in a cool, dry place.
Battery Replacement
To change the batteries, do the following:
1. Loosen the screw on the battery compartment door
located on the left side of the headphones.
2. Replace the two AAA batteries in the compartment.
Make sure that they are installed correctly.
3. Tighten the screws to close the compartment door.
If the headphones are to be stored for a long period
of time, remove the batteries and keep them in a cool,
dry place.
Stereo RCA Jacks
The RCA jacks and the mini-headphone jacks are
located behind the video screen on the overhead
console. The RCA jacks allow you to hook up an
auxiliary device such as a camcorder or a video game
unit. The yellow RCA jack is used for video and the
red and white RCA jacks are used for audio. You may
require adapter connectors or cables to connect
your auxiliary device to the RCA jacks. Refer to the
manufacturer's instructions for proper usage. The
mini-headphone jacks allow you to hook up two
customer provided wired headphones.
To use the auxiliary audio and video inputs on the RSE,
connect an external auxiliary device such as a
camcorder to the RCA jacks and turn on both the
auxiliary device power and the power on the front of the
RSE player. If a disc is not present in the player, the
auxiliary signal will immediately be displayed on
the RSE. If a disc is present when the RSE power is
turned on, the player will automatically begin playing the
disc and the user will need to press the AUX button
on the remote control to display and/or hear the auxiliary
input signals. Each press of the AUX button on the
remote control will switch the system between disc and
auxiliary input. The wired headphone volume control
will only operate when the DVD player power is turned
on and it controls both wired headphone jacks at
the same time. See
Remote Controllater in this section
for more information.

{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You can't see it or
smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow
doesn't collect there.
Open a window just a little on the side of the
vehicle that's away from the wind. This will
help keep CO out.Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.

Dinghy Towing
When towing your vehicle, turn the ignition off. To
prevent your battery from draining while towing, remove
the Ignition A and the Ignition B fuses from the engine
compartment fuse block. Be sure to reinstall the
fuse when you reach your destination.
Two-Wheel-Drive Vehicles
Two-wheel-drive vehicles should not be towed with all
four wheels on the ground. Two-wheel-drive
transmissions have no provisions for internal lubrication
while being towed. To properly tow these vehicles,
they should be placed on a platform trailer.
In rare cases when it's unavoidable that a
two-wheel-drive vehicle is to be towed with all four
wheels on the ground, the propeller shaft to axle yoke
orientation should be marked and the propeller shaft
removed following the applicable service manual
removal/installation procedure.
Dust or dirt can enter the back of the transmission
through the opening created by removing the propeller
shaft if proper protection is not provided. Also, check
the transmission ¯uid level before driving the truck.
Four-Wheel-Drive Vehicles
Use the following procedure to tow your vehicle:
1. Firmly set the parking brake.
2. Shift the transmission to PARK (P).
3. Securely attach the vehicle being towed to the tow
vehicle.
