Interior Features
Audio System
Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterized by sound breakup.
Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 1
88.1 MHz
5–16
Station 2
88.3 MHz
Operating Tips for CD Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in
the CD player may become clouded with
condensation. At this time, the CD will
eject immediately when placed in the unit.
A clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about
an hour. Wait for normal operation to
return before attempting to use the unit.
Handling the CD player
The following precautions should be
observed.
Do not use deformed or cracked CDs.

The disc may not eject resulting in a
malfunction.
Do not use non-conventional discs such

as heart-shaped, octagonal discs, etc.
The disc may not eject resulting in a
malfunction.
