2-3. Operating the lights and windshield wipers
2
When driving
IS F_EE
The windshield wipers and washer can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
Effects of vehicle speed on wiper operation
With the settings other than “AUTO” also, the time until drip prevention
wiper sweep occurs is changed depending on vehicle speed.
Low speed wiper operation selected, wiper operation will be switched from
low speed to intermittent wiper operation only when the vehicle is station-
ary.
“AUTO” mode
If the wiper switch is turned to the “AUTO” position while the
“ENGINE START STOP” switch is in IGNITION ON mode, the wiper
will operate once to show that auto mode is activated.
If the temperature of the raindrop sensor is 90C (194F) or higher, or -
30C (-22F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
Outside rear view mirror defogger activation linked to windshield wiper
operation
The outside rear view mirror defogger automatically turns on when you
operate the windshield wipers.
The raindrop sensor judges the
amount of raindrops.
The sensitivity of sensor can be
adjusted by turning the knob.
Increases the sensitivity
Decreases the sensitivity

2-4. Using other driving systems
IS F_EE
When passing an oncoming vehicle on a right-turn (right-hand drive
countries) or left-turn (left-hand drive countries)
When your vehicle rapidly closes on the vehicle in front
When a grade separation/interchange, sign, billboard, or other structure
appears to be directly in the vehicle's line of travel.
When an overhead billboard or other metallic structure appears to be in
the vehicle’s direct line of travel due to driving on a hill.
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
When passing through certain toll gates
When driving on a bridge.
When the system is activated in the situations described above there is also a
possibility that the seat belts will retract quickly and the brakes will be
applied with a force greater than normal. When the seat belt is locked in the
retracted position, stop the vehicle in a safe place, release the seat belt and
refasten.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on or flash. (P. 425,
431)
Situations in which the pre-crash safety system does not function properly
The system may not function effectively in situations such as the following:
On roads with sharp bends or uneven surfaces
If a vehicle suddenly moves in front of your vehicle, such as at an inter-
section
If a vehicle suddenly cuts in front of your vehicle, such as when overtak-
ing
In inclement weather such as heavy rain, fog, snow or sand storms
When your vehicle is skidding with the VSC system off
When an extreme change in vehicle height occurs
When the axis of the radar is out of adjustment
Automatic cancelation of the pre-crash safety system
When a malfunction occurs due to sensor contamination, etc. that results in
the sensors being unable to detect obstacles, the pre-crash safety system will
be automatically disabled. In this case, the system will not activate even if
there is a collision possibility.

3-1. Using the air conditioning system and defogger
IS F_EE
Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions. As a result, the following may occur.
Immediately after is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
Cool air may flow to the area around the upper body when the heater is
on.
Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used for an
extended period.
Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to
in accordance with the temperature setting and the inside temperature.
Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode
in situations where the windows need to be defogged.
When outside air temperature approaches 0C (32F)
The air conditioning system may not operate even when is pressed.
When the indicator light on flashes
Press and turn off the air conditioning system before turning it on
once more. There may be a problem in the air conditioning system if the
indicator light continues to flash. Turn the air conditioning system off and
have it inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and
automatically switches between outside air and recirculated air modes.

Maintenance and care
IS F_EE
NOTICE
Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alka-
line solutions, dye, bleach or other detergent. Doing so may discolor the
vehicle interior or cause streaks or damage to painted surfaces.
Do not use polish wax or polish cleaner. The instrument panel's or other
interior part’s painted surface may be damaged.
Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
Remove any dust or dirt on leather surfaces immediately.
Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
Do not place items made of vinyl, plastic, or that contain wax on the
upholstery, as they may stick to the leather surface if the vehicle interior
heats up significantly.
Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes
into contact with electrical components under the floor of the vehicle, and
may also cause the body to rust.
Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause dam-
age to the rear window defogger heater wires or antenna. Use a cloth
dampened with lukewarm water to gently wipe the window clean. Wipe
the window in strokes running parallel to the heater wires or antenna.
Be careful not to scratch or damage the heater wires or antenna.
