AUDIO SYSTEM OPERATING HINTS

NOTICE
To ensure correct audio system operations:
D Be careful not to spill beverages over the audio
system.
D Do not put anything other than a cassette tape or CD
into the cassette tape slot or CD slot.
D The use of a cellular phone inside or near the vehicle
may cause a noise from the speakers of the audio
system which you are listening to. However, this
does not indicate a malfunction.

Radio reception

Usually, a problem with radio reception does not mean there is
a problem with your radio — it is just the normal result of
conditions outside the vehicle.
For example, nearby buildings and terrain can interfere with
FM reception. Power lines or telephone wires can interfere
with AM signals. And of course, radio signals have a limited
range. The farther you are from a station, the weaker its signal
will be. In addition, reception conditions change constantly as
your vehicle moves.
Here are some common reception problems that probably do
not indicate a problem with your radio:

FM

Fading and drifting stations — Generally, the effective range
of FM is about 40 km (25 miles). Once outside this range, you
may notice fading and drifting, which increase with the distance
from the radio transmitter. They are often accompanied by
distortion.
Multi path — FM signals are reflective, making it possible for
two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering — These occur when signals are
blocked by buildings, trees, or other large objects. Increasing
the bass level may reduce static and fluttering.
Station swapping — If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again.
