Using your audio system: some basics
This section describes some of the basic features of the Lexus
audio system. Some informat ion may not pertain to your
system.
Your audio system works when the ignition switch is in the
“ACC” or “ON” position.
NOTICE
To prevent the battery from being discharged, do not
leave the audio system on longer than necessary when
the engine is not running.
(a) Turning the system on and off
20L355
Push this knob to turn the audio system on and off. Turn
this knob to adjust the volume.
The system turns on in the last mode used.
20L356
Push the “AM·SAT”, “FM”, “TAPE” or “DISC” to turn on
that mode. The selected mode turns on directly.
Push these buttons if you want to switch from one mode to
another.
If the tape or CD is not set, the cassette player or CD player
does not turn on.
You can turn off the cassette player by ejecting the cassette
tape. If the audio system was previously off, then the entire
audio system will be turned off when you eject the cassette
tape. If another function was previously playing, it will come on
again.

Correct Wrong
 Handle CDs carefully, especially when you set them into the
player. Hold them on the edge and do not bend them. A void
getting fingerprints on them, particularly on the shiny side.
 Dirt, scratches, warping, pin holes, or other CD damage
could cause the player to skip or to repeat a section of a
track. (To see a pin hole, hold the CD up to the light.)
20L039
To clean a CD: 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 CD (not in a circle). Do not use a
conventional record cleaner or anti −static device.

STARTING AND DRIVING

Dynamic radar cruise control—
CAUTION
Certain conditions make vehicle detection difficult or
impossible.

As this system operates by detecting primarily the
reflected wave from the rear end of the vehicle ahead,
the distance cannot be accurately detected in the
following cases, resulting in improper
vehicletovehicle distance.
 The rear section of the vehicle ahead is extremely
small such as an unloaded trailer.
 The vehicle ahead or other vehicles around you
are flinging up water or snow.
 Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
 The millimeter wave radar sensor automatically
detects dirt if it is sticking to the front of the sensor
or grille cover of your vehicle, and if detected, a
message is shown on the multiinformation display.
However, if the sensor or grille cover is covered with
a metallic vinyl bag, icicle, snowflakes, etc., dirt may
not be detected, resulting in improper
vehicletovehicle distance. Continue driving with
due care to the vehicle ahead. If dirt is detected, the
dynamic radar cruise control function is
automatically cancelled. Always keep the sensor and
grille cover clean.

STARTING AND DRIVING
337
Dynamic laser cruise control—
CAUTION
Certain conditions make vehicle detection difficult or
impossible.

As this system operates by detecting primarily the
reflectors of the vehicle ahead, the distance cannot
be accurately detected in the following cases,
resulting in improper vehicletovehicle distance.
 The vehicle ahead has higher ground clearance,
which means that the placement of the reflectors
is in a higher position.
 The rear section of the vehicle ahead is extremely
dirty.
 The vehicle ahead or other vehicles around you
are flinging up water or snow.
 Excessive exhaust gas (black smoke) is coming
from the vehicle ahead or other vehicles around
you, obscuring your front view.
 Protective film is attached to the reflectors on the
vehicle ahead, or reflectors are not installed on the
vehicle ahead or are damaged.
 Heavy luggage which is loaded in your trunk or on
top of your rear seats is raising up the nose of your
vehicle.
 The laser radar sensor automatically detects dirt if it
is sticking to the sensor glass of your vehicle, and if
detected, a message is shown on the
multiinformation display. However, if the sensor
glass is covered with a transparent or translucent
vinyl bag, icicle, etc., dirt may not be detected,
resulting in improper vehicletovehicle distance.
Continue driving with due care to the vehicle ahead.
If dirt is detected, the dynamic laser cruise control
function is automatically cancelled. Always keep the
sensor glass clean.

STARTING AND DRIVING
378
Precaution for precollision safety system
It should be noted that the pre−collision sensor may detect the
following as the objects with which your vehicle might collide,
and the pre −collision safety may operate, even though there
is no possibility of collision.
 When traveling through a curve, there is an object on the
edge of the road.
 When traveling through a curve, another vehicle is passing
from the opposite direction.
 When traveling across a narrow iron bridge.
 When there is a metallic object on the road.
 When there is a steel plate on the road at a construction site.
 When there is a bump on the road.
 When waiting to turn to the left in an intersection, and
another vehicle is passing from the opposite direction.
 If your vehicle approaches another vehicle ahead very
quickly.CAUTION
Do not rely solely on the precollision safety system
to avoid accidents. Your safe and attentive driving
practices are still the best way to avoid accidents and
you are always responsible for the operation of the
vehicle and the safety of your passengers. When
driving, always pay attention to the surrounding
conditions and the course you are driving.
 The precollision sensor’s collision detection
performance is limited. The sensor is able to detect
a forward object within 10 degrees on either left or
right side. If it is out of the range, or if there is no or
weak millimeter wave reflection, the sensor could not
detect the object and the system does not work
properly.
 Even if the precollision safety is operative in an
unavoidable collision, unless the seat belts are worn
and the brake pedal is depressed, the precollision
seat belts and precollision brake assist system will
not work.
