376Radio 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.
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.)

LOCKº 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 ACCº to the LOCKº position, you must
put the transmission selector lever in the Pº position.
Once you remove the key, the engine immobilizer system is
automatically set. See Engine immobilizer systemº on page

When starting the engine, the key may seem stuck at the
LOCKº 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.
If, in an emergency, you must turn the engine off while the
vehicle is moving, turn the key only to ACCº.

NOTICE
Do not use liquid sealants for a flat tire as air pressuresensors will be damaged.
When the tires must be repaired or replaced, havethem repaired or replaced by the nearest Lexusdealer or authorized tire dealer. The tire pressuresensors will be affected by the installation or removal
of tires.
The tire pressure warning system is not to be used as a substitute for regular inspections. Be sure to check
the air pressure in the tires on a regular basis.
When the tires must be replaced, replace the grommets for air pressure sensors as well.
If the warning light blinks:
The tire pressure warning system may be malfunctioning.
Contact your Lexus dealer.System malfunction
The tire pressure warning system does not function
properly under certain circumstances. In the following
cases, the low tire pressure warning light may not come
on even if the tire inflation pressure is low, or it may come
on when the tire inflation pressure is actually normal.
 Electric devices or facilities using similar radio wave
frequencies are nearby.
 A radio set to similar frequencies is in use.
 A lot of snow or ice covers the vehicle, in particular, around
the wheels or wheel housings.
 The tires are not equipped with an air pressure sensor.
 Tire chains are used.
