Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 50 cm (1.6 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect obstacles
that are extremely close to the
vehicle.
The range of the sensors may
change depending on the shape of
the object etc.
■The Lexus parking assist-sensor can be operated when

■Sensor detection information
●Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an obstacle. Particular instances where this
may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other loud noises producing ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather.
• A non-genuine Lexus suspension (lowered suspension, etc.) is installed.
In addition to the examples above, there are instances in which, because of their
shapes, signs and other objects may be judged by a sensor to be closer than they
are.
●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 projecting outwards in the direction of your
vehicle

CAUTION
■Caution when using the Lexus parking assist-sensor
Observe the following precautions.
Failing to do so may result in the vehicle being unable to be driven safely and possi-
bly cause an accident.
●Do not use the sensor at speeds in excess of 10 km/h (6 mph).
●Do not attach any accessories within the sensor range.
NOTICE
■Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.
■Conditions possibly indicating system malfunctions
If any of the following occurs, the system may be malfunctioning due to a sensor fail-
ure etc. Have the vehicle inspected by any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
●The buzzer does not sound when the Lexus parking assist-sensor mode is set.
●The sensor operation display flashes and the buzzer sounds even when no obsta-
cle is detected.
●An area of the sensors is hit or subjected to a strong impact.
●Either bumper is hit.
●The sensor operation display remains on even though no buzzer sounds.

Pressing this switch while the vehi-
cle is in luggage mode changes the
vehicle height to that of “N” mode.
Lower
Pressing this switch while the vehi-
cle is in “N” mode changes the
vehicle height to that of luggage
mode, not “LO” mode.
■Electronically modulated air suspension indicator
The indicator for the selected
mode will come on.
The indicator will flash while the
vehicle height is being changed to
the height of the selected mode.
Disabling the height control
Press the height control off switch
while the vehicle is stopped. A
message will appear on the multi-
information display, and vehicle
height will be fixed in the current
mode.
When vehicle speed exceeds 30
km/h (19 mph), the electronically
modulated air suspension is re-
enabled automatically.

■Operating conditions
After stopping the engine, the vehicle will remain lowered for a maximum of 60
seconds.
●Height selector switch (driver's side instrument panel)
• While the engine is running, any vehicle height mode can be selected.
• Luggage mode can only be selected when the shift lever is in P position.
●Height selector switch (luggage compartment)
• When the engine is running and the shift lever is in the P position, any vehicle
height other than “LO” mode can be selected.
• When the “ENGINE START STOP” switch is turned off, the vehicle height
can only be lowered (only the “∨” side of the switch can be operated).
This switch can only be operated when the back door is open.
●Height control off switch
When the vehicle is stopped with the “ENGINE START STOP” switch in IGNI-
TION ON mode, vehicle height control can be disabled/re-enabled.
■When changing vehicle height modes
Before operating the height selector switch to raise/lower the vehicle height,
ensure that there are no objects in the surrounding area that could damage the
vehicle.
■When “N” mode is selected
During high speed driving, the vehicle height will automatically change to that of
“LO” mode.
■When “HI” mode is selected
The vehicle height will change to that of “N” mode when vehicle speed reaches 50
km/h (31 mph) or when vehicle speed has exceeded 30 km/h (19 mph) for approx-
imately 10 seconds. Even if vehicle speed is reduced below 30 km/h (19 mph), the
vehicle height will not automatically return to “HI” mode.
■When “LO” mode is selected
The vehicle height will change to that of “N” mode when the engine is restarted.

■When luggage mode is selected
If the vehicle begins to move while still in luggage mode, the vehicle will automati-
cally change to “N” mode once speed exceeds 8 km/h (5 mph). Even if vehicle
speed is reduced below 8 km/h (5 mph), the vehicle height will not automatically
return to luggage mode.
■Operating sound of the air suspension
When the vehicle height is lowered, such as when entering and loading the vehicle,
or when the height selector switch is operated, the sound of the compressor oper-
ating or the mode changing may be heard. This does not indicate a malfunction.
■Automatic leveling function
Regardless of the number of occupants and the luggage load, vehicle height in any
mode is always adjusted to a fixed height by the automatic leveling function.
■Vehicle height mode change time
●If the height control is operated continuously to lower the vehicle, the suspen-
sion air tank may become full, causing operation of the vehicle height lowering
control to become slow.
●To protect the compressor, the system will only raise the vehicle for a total of
100 consecutive seconds. If it takes longer than this to reach the selected
height, operation may be suspended shortly and then restart. However, it may
not be possible to change the vehicle's height mode at this time.
■The electronically modulated air suspension will not operate when
The vehicle height control may not be able to change modes when the vehicle runs
over a high curb or other rugged surfaces where the suspension is stretched.
