■Effects of vehicle speed on wiper operation (vehicles with rain-sensing windshield wip-
ers)
With the settings other than “AUTO” also, the time until drip prevention wiper sweep
occurs is changed depending on vehicle speed.
With the low speed wiper operation selected, wiper operation will be switched from low
speed to intermittent wiper operation only when the vehicle is stationary. (However,
when the sensor sensitivity is adjusted to the highest level, the mode cannot be switched.)
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
WARNING
■Caution regarding the use of windshield wipe rs in “AUTO” mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in “AUTO” mo de. Take care that your fingers etc. anything
else does not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.
NOTICE
■When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may overheat.
■When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be cau sed if the lever is pulled toward you and
held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

■Dynamic radar cruise control can be set when
●The shift lever is in D.
●Vehicle speed is at or above approximately 30 mph (50 km/h).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the
set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-
cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.
■Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●Actual vehicle speed falls at or below approximately 25 mph (40 km/h).
●VSC is activated.
●Active TRAC is activated for a period of time.
●When the VSC or Active TR AC system is turned off.
●When second start mode is set.
●The sensor cannot detect correctly because it is covered in some way.
●Pre-collision braking is activated.
●The switching operation continues for 5 seco nds or more after the center differential
lock switch has been operated.
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in th e system. Contact your Lexus dealer.
■Automatic cancelation of constant speed control mode
Constant speed control mode is automatica lly canceled in the following situations:
●Actual vehicle speed is more than approxim ately 10 mph (16 km/h) below the set vehi-
cle speed.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●Active TRAC is activated for a period of time.
●When the VSC or Active TRAC system is turned off.
●Pre-collision braking is activated.
●The switching operation continues for 5 seco nds or more after the center differential
lock switch has been operated.
If constant speed control mode is automati cally canceled for any other reason, there may
be a malfunction in the system . Contact your Lexus dealer.
■Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehicle distance
control mode, a brake system operation sound may be heard. This does not indicate a
malfunction.

WARNING
■The rear height control air suspension must be turned off
Be sure to observe the following precautions. Otherwise, the automatic leveling func-
tion may cause vehicle height to change, an
d you may catch part of your body in the
vehicle, resulting in an accident:
●When jacking up the vehicle, installing tire chains or tying the vehicle with chains/
wires for transportation via flatbed truck, tu rn off the rear height control air suspen-
sion and stop the engine.
●When the vehicle must be towed or disconnect ing a trailer, put the vehicle height in N
mode and turn off the rear he ight control air suspension.
●When the vehicle is stuck, turn off the rear height control air suspension.
■Selecting the correct height mode
●HI mode should only be used when drivin g on rough roads, for example when driving
off-road.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Do not select HI mode when loading cargo on the roof luggage carrier.
Because the vehicle’s center of gravity will become higher when in the mode, the
vehicle may become unstable when turnin g abruptly, resulting in an accident.
●Before lowering vehicle height, check that there is no one under the vehicle.
NOTICE
■Be careful in any place where overhead space is limited
The vehicle height will rise when a higher mode is selected or cargo is unloaded. This
may cause damage to the vehicle.
■Do not select LO mode when driving on bumpy roads
If the underbody of the vehicle touches a rugged road surface, the vehicle may be
damaged.
■Changing vehicle height
Do not change vehicle height frequently.
The compressor may overheat and stop operation.
■When on the extremely uneven roads with rocks
Sometimes the vehicle height is not adjusted because it is judged as uneven road driv-
ing.
