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.

Handle CDs carefully, especially when you are inserting
them. 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.)
 Remove CDs from the CD player when you are not listening
to them. Store them in their plastic cases away from
moisture, heat, and direct sunlight.
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 circles). Dry it with another soft,
lint±free cloth. Do not use a conventional record cleaner or
anti±static device.

STARTING AND DRIVING

If the engine becomes difficult to start or stalls
frequently, take your vehicle in for a check±up assoon as possible. Remember, your Lexus dealerknows your vehicle and its three±way catalyticconverter system best.
To ensure that the three±way catalytic converter andthe entire emission control system operate properly,your vehicle must receive the periodic inspectionsrequired by the Lexus Maintenance Schedule. For
scheduled maintenance information, refer to theªOwner's Manual Supplement/ScheduledMaintenanceº.

418THE REAR VIEW MONITOR SYSTEM CAMERA
The rear view monitor system camera is located on the back
door as shown in the illustration. The camera uses a special
lens. The distance of the image that appears on the screen
differs from the actual distance.
In the following cases, it may become difficult to
see the images
on the screen, even when the system is functioning.
 In the dark (for example, at night)
 When the temperature near the lens is extremely high or low
 When water droplets are adhering to the camera, or when
humidity is high (for example, when it rains)
 When foreign matter (for example, snow or mud) adheres
to the camera lens
 When the sun or the beam of headlights is shining directly
into the camera lens
Check surroundings for safety.
If a bright light (for example, sunlight reflected off the vehicle
body) is picked up by the camera, the smear effect* peculiar to
the camera may occur.
*: Smear effect Ð A phenomenon that occurs when a bright
light (for example, sunlight reflected off the vehicle body) is
picked up by the camera; when transmitted by the camera, the
light source appears to have a vertical streak above and below
it.

4Resetting to a slower speed
Press the control lever downward in the ª± SETº direction and
hold it. Release the lever when the desired speed is attained.
While the lever is held downward, the vehicle speed will
gradually decrease.
When the difference between the actual vehicle speed and the
set speed is less than 5 km/h (3 mph), the set speed can be
lowered 1.6 km/h (1 mph) each time by pressing the control
lever downward in the ª± SETº direction quickly.
However, a quicker way to reset is to depress the brake pedal
and then press the control lever downward in the ª± SETº
direction.
Even if you downshift the transmission from the ªDº position to
ª4º position with the cruise control on, engine braking will not
be applied because the cruise control is not cancelled. To
decrease the vehicle speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
5Resuming the preset speed
If the preset speed is cancelled by pulling the control lever or
by depressing the brake pedal, pushing the lever up in the ª+
RESº direction will restore the speed set prior to cancellation.
Cruise control failure warning
If the ªCRUISEº indicator light in the instrument cluster flashes
when using the cruise control, push the ºON±OFFº button to
turn the system off and then push it again to turn it on.
If any of the following conditions then occurs, there is some
trouble in the cruise control system.
 The indicator light does not come on.
 The indicator light flashes again.
 The indicator light goes out after it comes on.
If this is the case, contact your Lexus dealer and have your
Lexus inspected.

VEHICLE STABILITY CONTROLSYSTEM
The vehicle stability control system helps provide
integrated control of the systems such as anti±lock brake
system, traction control, engine control, etc. This system
automatically controls the output of the brakes or engine
to help prevent the vehicle from skidding when cornering
on a slippery road surface or operating steering wheel
abruptly.
This system activates when the vehicle speed about more than
15 km/h (9mph).
You may hear a sound in the engine compartment for a few
seconds when the engine is started or just after the vehicle
begins to move. This means that the system is in the
self±check mode, but does not indicate a malfunction.
CAUTION
 Do not rely excessively on the vehicle stability
control system. Even if the vehicle stability control
system is operating, you must always drive carefully
and attentively to avoid serious injury. Reckless
driving will result in an unexpected accident. If the
slip indicator light blinks and an alarm sounds,
special care should be taken while driving.
Only use tires of specified size. The size,
manufacturer, brand and tread pattern for all 4 tires
should be the same. If you use the tires other than
specified, or different type or size, the vehicle
stability control system may not function correctly.
When replacing the tires or wheels, contact your
Lexus dealer.
 In situations where the road surface is covered with
ice or snow, your vehicle should be fitted with snow
tires or tire chains.

Slip indicator light
If the vehicle is going to skid during driving, the slip indicator
light blinks and an alarm sounds intermittently. Special care
should be taken while driving.

STARTING AND DRIVING
444
Driving over the steps such as the joints on the road.
 Driving on roads where the road surface is pitted or
has other differences in surface height.
Install all 4 tires of specified size at appropriate
pressure: The anti±lock brake system detects vehicle
speeds using the speed sensors for respective wheels'
turning speeds. The use of tires other than specified
may fail to detect the accurate turning speed resulting
in a longer stopping distance.ªABSº warning light

1U.S.A.2Canada
The light comes on when the ignition key is turned to the ªONº
position. If the anti±lock brake system and the brake assist
system work properly, the light turns off after a few seconds.
Thereafter, if either of the systems malfunctions, the light
comes on again.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system, the brake
assist system, the active traction control system and the
vehicle stability control system do/does not operate, but the
brake system still operates conventionally.
When the ªABSº warning light is on (and the brake system
warning light is off), the anti±lock brake system does not
operate so that the wheels could lock up during a sudden
braking or braking on slippery road surfaces.

TIRE PRESSURE WARNINGSYSTEM
The tire pressure warning system is designed to provide
warning when tire inflation pressure of one or more of
your tires (including the spare tire) is low. The low tire
pressure warning light comes on to inform you that low
tire inflation pressure may hamper driving.

Low tire pressure warning light
This light comes on when the ignition key is turned to the ªONº
position. It goes off after a few seconds. This indicates that the
tire pressure warning system is functioning properly. If the low tire pressure warning light comes on or blinks,
do the following.
If the warning light comes on:
Stop your vehicle in a safe place as soon as possible and
check that the inflation pressure of all tires (including the
spare tire) is as specified on the tire and loading
information
label. (See ªChecking tire inflation pressureº
on page 574.) If the warning light comes on even after tire
inflation pressure adjustment, you may have a flat tire. If
you have a flat tire, replace it with the spare tire. For
details, see ªIf you have a flat tireº on page 497.
The warning light goes off a few minutes after air is put into the
deflated tire.
This warning light may turn on due to natural causes such as
natural air leaks or tire pressure changes caused by
temperature. In this case, adjusting the tire pressure will turn
off the warning light.
