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 CD player and CDs

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

AUDIO

AM
Fading Ð AM broadcasts are reflected by the upper
atmosphere Ð especially at night. These reflected signals can
interfere with those received directly from the radio station,
causing
the radio station to sound alternately strong and weak.
Station interference Ð When a reflected signal and a signal
received directly from a radio station are very nearly the same
frequency, they can interfere with each other, making it dif ficult
to hear the broadcast.
Static Ð AM is easily affected by external sources of electrical
noise, such as high tension power lines, lightening, or electrical
motors. This results in static.
Caring for your cassette player and tapes
For the best performance for your cassette player and tapes:
Clean the tape head and other parts regularly.
 A dirty tape head or tape path can decrease sound quality
and tangle your cassette tapes. The easiest way to clean
them is by using a cleaning tape. (A wet type is
recommended.) 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 CD player, DVD player and CDs
 Your CD player and DVD player are intended for use with 12
cm (4.7 in.) CDs only.
 Extremely high temperatures can keep your CD player and
DVD player from working. On hot days, use the air
conditioning to cool the vehicle interior before you use the
players.
 Bumpy roads or other vibrations may make your CD player
and DVD player skip.

REAR HEIGHT CONTROL AIRSUSPENSION
This rear height control air suspension controls the
vehicle height depending on the vehicle driving condition.
Select your desired height among the ªHIº (high), ªNº
(normal) and ªLOº (low) modes with the height select
switch.
(a) Vehicle height modes
ªNº (normal) mode: The vehicle height in this mode is
standard. Regardless of the number of occupants or the
luggage loading condition, the vehicle height is always
automatically adjusted to a fixed height in any mode while the
engine is running.
This mode is suitable for ordinary driving. ªHIº
(high) mode: The vehicle height is about 40 mm (1.6 in.)
higher at the rear than the ªNº mode height.
This mode is suitable when driving on the bumpy roads and
through water.
However, when the vehicle speed exceeds about 30 km/h (19
mph) or over in the ªHIº mode, the ªNº mode is automaticall\
y
selected.
CAUTION
The ªHIº mode should be used for severe off±road
driving condition only. As the vehicle's center of gravity
is higher in this setting, the vehicle may become
unstable when turning abruptly resulting in accident.
ªLOº (low) mode: The vehicle height is about 20 mm (0.8 in.)
lower at the rear than the ªNº mode height.
This mode allows you easy access to the vehicle (getting in and
out) and easy loading and unloading operation.
This mode is available when the vehicle speed is under about
12 km/h (7 mph).
