◆Pre-collision braking*3
When the system determines that the possibility of a frontal collision is high,
the system warns the driver. If the system determines that the possibility of a
collision is extremely high, the brakes are automatically applied to help avoid
the collision or reduce the collision speed.
*3: Depending on the region in which the vehi cle was sold, the pre-collision braking func-
tion may not be available.
◆Suspension control
When the system determines that the po ssibility of a frontal collision is high,
the Adaptive Variable Suspension System ( P. 379) will control the damping
force of the shock absorbers.

■The intuitive parking assist can be operated when
●Front corner sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P.
• The vehicle speed is less than approximately 6 mph (10 km/h).
(At any speed when the shift lever is in R)
●Front center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in a position other than P or R.
• The vehicle speed is less than about 6 mph (10 km/h).
●Rear corner and rear center sensors:
• The engine switch is in IGNITION ON mode.
• The shift lever is in R.
■Intuitive parking assist display
When an obstacle is detected while the re ar view monitor system, Lexus parking assist
monitor or Multi-terrain Monitor is in use, the warning indicator will appear in the upper
corner of the screen even if the display setting has been set to off.
■Sensor detectio n information
●The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●Certain vehicle conditions and the surround ing 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 the sensor . (Wiping the sensors will resolve this prob-
lem.)
• The sensor is frozen. (Thawing th e area will resolve this problem.)
In especially cold weather, if a sensor is frozen the screen may show an abnormal
display, or obstacles may not be detected.
• The sensor is covered in any way.
• The vehicle is leaning co nsiderably 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.
• The sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or wireless antenna.
• The bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or curved curb.
• In harsh sunlight or intense cold weather.
• The area directly under the bumpers is not detected.
• If obstacles draw too close to the sensor.
• A non-genuine Lexus suspension (low ered suspension etc.) is installed.
• People may not be detected if they are wearing certain types of clothing.
In addition to the examples above, there are instances in which, because of their shape,
signs and other objects may be judged by a sensor to be closer than they are.

■In the following cases the 4-Wheel AHC will not operate
●The brake pedal has been depressed for a few seconds or longer while the vehicle is
stopped.
●Vehicle height control has not been frequently used.
●The suspension fluid temperature is lower than -22°F (-30°C).
●There is ice on the suspension.
●Driving on bumpy roads which may cause
the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the center
differential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid temperature
drops below 5°F (-15°C).
The 4-Wheel AHC does not operate when the suspension fluid temperature drops
below -22°F (-30°C).
●In this case, even if the height select switch is pressed, th e vehicle height will not change.
Once the vehicle has been driven for a short time and the suspension fluid has been
warmed to within normal operating limits, the 4-Wheel AHC will begin operating and
the vehicle height will automatically change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not be able
to be raised, even if the 4-Wheel AHC is oper ating. In this case, pull the height select
switch to “ ” then push to “ ” after driving for a short time longer to select the desired
vehicle height.
■Parking and stopping tips
●If you immediately stop the engine after off-road driving, the vehicle height may gradu-
ally lower. When parking, make sure ther e is nothing under the vehicle that may come
in contact with the underbody. The vehicle will return to the set height when the engine
is started.
●The vehicle height may change as the temperature changes when the engine is
stopped. The vehicle will return to the set height when the engine is started.
■Propeller shaft noise
If the vehicle height is adjusted on a slope, or with the shift lever in a position other than P
or N while the vehicle is stopped, you may hear a sound caused by the expansion and
contraction of the propeller shaft. Th is does not indicate a malfunction.
■4-Wheel AHC failure warning
If a malfunction occurs in the 4-Wheel AHC , normal mode is automatically selected.
However, the system may not switch to norm al mode depending on the location of the
malfunction.
The warning message is displayed on the mu lti-information display, and the 4-Wheel
AHC cannot be activated until the malfunction is corrected.
Stop the engine and start it again. If the warning message turns off, the system is operat-
ing correctly. If the warning message continue s to be displayed, have the vehicle checked
at your Lexus dealer as soon as possible.
