The air conditioning filter is behind the glove box.
The air conditioning filter may clog after long use. The filter
may need to be replaced if the air flow of the air conditioner and
heater experiences extreme reductions in operating ef ficiency,
or if the windows begin to fog up easily.
To maintain the air conditioning efficiency, inspect and replace
the air conditioning filter according to the maintenance
schedule. In dusty areas or areas with heavy traffic flow, such
as inner city or desert areas, early replacement may be
required. (For scheduled maintenance information, please
refer to the Owner's Manual Supplement/Scheduled
Maintenanceº.)1. Open the glove box and unhook the cip as shown

AUDIO

Use high-quality cassettes:

Low-quality cassette tapes can cause many problems,
including poor sound, inconsistent playing speed, and
constant auto-reversing. They can also get stuck or tangled
in the cassette player.
 Do not use a cassette if it has been damaged or tangled or
if its label is peeling off.
 Do not leave a cassette in the player if you are not listening
to it, especially if it is hot outside.
 Store cassettes in their cases and out of direct sunlight.
 Avoid using cassettes with a total playing time longer than
100 minutes (50 minutes per side). The tape used in these
cassettes is thin and could get stuck or tangled in the
cassette player. Caring for your compact disc player and discs

Your compact disc player is intended for use with 12 cm (4.7
in.) discs only.
 Extremely high temperature can keep your compact disc
player from working. On hot days, use air conditioning to
cool the vehicle interior before you listen to a disc.
 Bumpy roads or other vibrations may make your compact
disc player skip.
 If moisture gets into your compact disc player, you may not
hear any sound even though your compact disc player
appears to be working. Eject all discs from the player and
wait until the player dries.
CAUTION
Compact disc players use an invisible laser beam which
could cause hazardous radiation exposure if directed
outside the unit. Be sure to operate the player correctly.

DRIVING TIPS
470
Because of the added load of the trailer, your vehicle's
engine may overheat on hot days (at temperatures over
30C [85 F]) when going up a long or steep grade with a
trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.
See If your vehicle overheatsº on page 485.
 Always place wheel blocks under both the vehicle and trailer
wheels when parking. Apply the parking brake firmly. Put
the transmission in Pº. Avoid parking on a slope with a
trailer, but if it cannot be avoided, do so only after performing
the following:
1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle
and trailer wheels.
3. When the wheel blocks are in place, release your brakes
slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into Pº and turn off the engine. When restarting out after parking on a slope:
1. With the transmission in Pº position, start the engine. Be
sure to keep the brake pedal depressed.
2. Shift into the 3º, 2º, Lº or Rº position.
3. Release the parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.
CAUTION

Do not exceed 72 km/h (45 mph) or the posted towing
speed limit, whichever is lower. Because instability
(swaying) of a towing vehicle-trailer combination
usually increases as the speed increases, exceeding
72 km/h (45 mph) may cause loss of control.
 Slow down and downshift before descending steep
or long downhill grades. Do not make sudden
downshifts.
 Avoid holding the brake pedal down too long or too
frequently. This could cause the brakes to overheat
and result in reduced braking efficiency.
