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 your
vehicle. Many times, this damage would not be covered
by your vehicle’s warranty, and it could be costly. But
the notice will tell you 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 your 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:

Front Storage Area
If your vehicle has this console compartment, squeeze
the front lever while lifting the top to open it. You
can store cassettes and compact discs in the slots in
front of the compartment.
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 to expose the storage area which includes
slots for cassettes or compact discs.
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.
A luggage carrier allows you to load things on top of
your vehicle. The luggage carrier has side rails attached
to the roof, sliding crossrails (if equipped) and places
to use for tying things down. These let you load
some other things on top of your vehicle, as long as
they are not wider or longer than the luggage carrier.
