the same words, CAUTION or NOTICE.

If your vehicle has air conditioning, your heating/air
conditioning controls will look like this:
On hot days, open the windows to let hot inside air
escape; then close them. This helps to reduce the time
it takes for your vehicle to cool down. It also helps
the system to operate more efficiently.
A/C (Air Conditioning):This setting will begin to cool
and dehumidify the air inside of your vehicle.
MAX A/C (Maximum Air Conditioning):Turn the right
knob to MAX A/C for maximum cooling. This setting
cools the air the fastest, by recirculating the inside air.
Rear Heating System
Your vehicle may have an optional rear heating system
that allows you to adjust the amount of air ¯owing
into the rear of the vehicle, from the front-seating area.
This feature works with the main climate-control
system in your vehicle.AUX (Auxiliary Heating System):The thumbwheel for
this system is located to the right of the audio system.
9(Fan):Turn the thumbwheel up or down to increase
or decrease the amount of heated air sent to the
rear-seating area.
9(Off):Turn the thumbwheel to this position to turn
off the rear heating system.

Audio System(s)
Notice:Before you add any sound equipment to
your vehicle ± like a tape player, CB radio, mobile
telephone or two-way radio ± be sure you can
add what you want. If you can, it's 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
improperly.
So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it ®rst. Figure out which radio you have in your vehicle,
®nd out what your audio system can do and how to
operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, you can play your
audio system even after the ignition is turned off.
See ªRetained Accessory Power (RAP)º underIgnition
