Vehicle Damage Warnings
Also, in this manual you will nd these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice tells about something that can damage the
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell what to do to help avoid the damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors
or in different words.
There are also warning labels on the vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
The vehicle has components and labels that use
symbols instead of text. Symbols are shown along
with the text describing the operation or information
relating to a specic component, control, message,
gage, or indicator.
If you need help guring out a specic name of a
component, gage, or indicator, reference the
following topics:

Center Console Storage Area
If your vehicle has this console compartment, squeeze
the front lever while lifting the top to open it.
Your vehicle’s console will be equipped with cupholders
located on the front and rear of the storage
compartment.
The console may also contain one or more of the
following components:
Rear Seat Audio Controls
Rear Seat Accessory Power Outlets
Rear Climate Control
If your vehicle has the center armrest compartment, lift
the cover by pulling up on the latch handle located
underneath the front edge of the armrest. The storage
area includes slots for cassettes or compact discs.
Assist Handles
A handle above each door can be used when getting
out of your vehicle.
Luggage Carrier
{CAUTION:
If you try to carry something on top of your
vehicle that is longer or wider than the luggage
carrier — like paneling, plywood, a mattress
and so forth — the wind can catch it as you
drive along. This can cause you to lose
control. What you are carrying could be
violently torn off, and this could cause you or
other drivers to have a collision, and of course
damage your vehicle. You may be able to carry
something like this inside. But, never carry
something longer or wider than the luggage
carrier on top of your vehicle.

CB radio, mobile telephone, or two-way radio,
make sure that it can be added by checking with
your dealer. Also, check federal rules covering
mobile radio and telephone units. If sound
equipment can be added, it is very important to do
it properly. Added sound equipment may interfere
with the operation of your vehicle’s engine, radio,
or other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.

operate through the GM radio/entertainment
system. If that equipment is replaced or additional
equipment is added to your vehicle, the chimes may
not work. Make sure that replacement or additional
equipment is compatible with your vehicle before
installing it.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. SeeRetained
