6. TIPS FOR OPERATING THE AUDIO/VISUAL SYSTEM
IS250/350_Navi_U
Fading and drifting stations: Generally, the
effective range of FM is about 25 miles (40
km). Once outside this range, you may no-
tice fading and drifting, which increase with
the distance from the radio transmitter.
They are often accompanied by distortion.
Multi-path: FM signals are reflective, mak-
ing it possible for 2 signals to reach the vehi-
cle’s 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 sig-
nals are blocked by buildings, trees or other
large objects. Increasing the bass level may
reduce static and fluttering.
Station swapping: If the FM signal being lis-
tened to is interrupted or weakened, and
there is another strong station nearby on
the FM band, the radio may tune in the sec-
ond station until the original signal can be
picked up again.Fading: AM broadcasts are reflected by the
upper atmosphere — especially at night.
These reflected signals can interfere with
those received directly from the radio sta-
tion, causing the radio station to sound al-
ternately strong and weak.
Station interference: When a reflected sig-
nal and a signal received directly from a ra-
dio station are very nearly the same
frequency, they can interfere with each oth-
er, making it difficult to hear the broadcast.
Static: AM is easily affected by external
sources of electrical noise, such as high ten-
sion power lines, lightening or electrical
motors. This results in static.

4zHandle discs carefully, especially when
inserting them. Hold th em on the edge and
do not bend them. Avoid getting finger-
prints on them, partic ularly on the shiny
side.
z Dirt, scratches, warpin g, pin holes or other
disc damage could cause the player to skip
or to repeat a section of a track. (To see a
pin hole, hold the disc up to the light.)
z Remove discs from the players when not in
use. Store them in their plastic cases away
from moisture, heat and direct sunlight.
To c l e a n a d i s c : Wipe it with a soft, lint-free
cloth that has been dampened with water.
Wipe in a straight line from the center to the
edge of the disc (not in circles). Dry it with
another soft, lint-free cloth. Do not use a
conventional record cleaner or anti-static
device.
z CD-R/CD-RW discs that have not been
subject to the “finalizing process” (a pro-
cess that allows discs to be played on a
conventional CD player) cannot be played.
z It may not be possible to play CD-R/CD-RW
discs recorded on a music CD recorder or a
personal computer because of disc charac-
teristics, scratches or dirt on the disc, or dirt,
condensation, etc. on the lens of the unit.
z It may not be possible to play discs
recorded on a personal computer depend-
ing on the application settings and the envi-
ronment. Record with the correct format.
(For details, contact the appropriate appli-
cation manufacturers of the applications.)
z CD-R/CD-RW discs may be damaged by
direct exposure to sunlight, high tempera-
tures or other storage conditions. The unit
may be unable to play some damaged
discs.
z If you insert a CD-RW disc into the player,
playback will begin more slowly than with a
conventional CD or CD-R disc.
z Recordings on CD-R/CD-RW cannot be
played using the DDCD (Double Density
CD) system.

•The vehicle is tilted. (There
is a heavy load on the vehi-
cle, tire pressure is low due
to a tire puncture, etc.)
• The vehicle is used on an
incline.If this happens due to these
causes, it does not indicate a
malfunction.

zThe vehicle is approaching a tall or right-
angled curb.
z In harsh sunlight or intense cold weather.
z A non-genuine Lexus suspension (lowered
suspension etc.) is installed.
z The shape of the obstacle may prevent a
sensor from detecting it. Pay particular
attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that
absorb sound waves
• Sharply-angled objects
• Low obstacles
• Tall obstacles with upper sections project- ing outwards in the direction of your vehi-
cle
z In addition to the examples above, there
are instances in which, because of their
shapes, signs and ot her objects may be
judged by a sensor to be closer than they
are.
CAUTION
● Caution when using the intuitive parking
assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle
being unable to be driven safely and pos-
sibly cause an accident.
• Do not use the sensor at speeds in excess of 6 mph (10 km/h).
• Do not attach any accessories within the sensor range.
● Even though sensors which are function-
ing properly continue to detect obstacles,
never use the intuitive parking assist if
one more sensor(s) may be malfunction-
ing.
