384Radio reception
Usually, a
problem with radio reception does not mean there is
a problem with your radio Ð 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 Ð 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 Ð 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 Ð These occur when signals are
blocked by buildings, trees, or other large objects. Increasing
the bass level may reduce static and fluttering.
Station swapping Ð 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.

AUDIO
385
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.

STARTING AND DRIVING
399
ªACCº Ð Accessories such as the radio operate, but the
engine is off.
If you leave the key in the ªACCº or ªLOCKº position and open
the driver's door, a buzzer will remind you to remove the key.
ªLOCKº Ð Engine is off and the steering wheel is locked.
The ignition key can be removed only at this position.
To turn the key from ªACCº to the ªLOCKº position, you must
put the transmission selector lever in the ªPº position.
Once you remove the key, the engine immobilizer system is
automatically set. See ªEngine immobilizer systemº on page
14.
When starting the engine, the key may seem stuck at the
ªLOCKº position. To free it, first be sure the key is pushed all
the way in, and then rock the steering wheel slightly while
turning the key gently.
Approximately
five hours after the engine is turned off, you may
hear sound coming from underneath the luggage compartment
for several minutes. This is normal operation and does not
indicate a malfunction. (See ªLeak detection pumpº on page
vi.)
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to ªACCº.
