CAUTION
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise control in any of the following situations.

Doing so may result in inappropriate speed control and could cause an accident
resulting in death or serious injury.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as those covered with rain, ice and snow
●On steep downhills, or where there are sudden changes between sharp up and
down gradients
Vehicle speed may exceed the set speed when driving down a steep hill.
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, heavy rain, etc.)
●When an approach warning buzzer is heard often
●During emergency towing
■When the sensor may not be correctly detecting the vehicle ahead
Apply the brakes as necessary when any of the following types of vehicles are in
front of you.
As the sensor may not be able to correctly detect these types of vehicles, the
approach warning (P. 178) will not be activated, and a fatal or serious accident
may result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (trailers with no load on board etc.)
●Motorcycles traveling in the same lane

CAUTION
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the following conditions as the radar sensor may
not be able to correctly detect vehicles ahead, and a serious or fatal accident may
result:
●When water or snow thrown up by the surrounding vehicles hinders the function-
ing of the sensor
●When your vehicle is pointing upwards (caused by a heavy load in the trunk etc.)
●When the road curves or when the lanes are narrow
●When steering wheel operation or your position in the lane is unstable
●When the vehicle ahead of you decelerates suddenly
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
Otherwise, the system may not function correctly and could result in an accident.
●Keep the sensor and front grille cover clean at all times.
Clean the sensor and front grille cover with a soft cloth so you do not mark or
damage them.
●Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunction. If the
sensor or surrounding area is subject to a strong impact, always have the area
inspected and adjusted by a Lexus dealer.
●Do not disassemble the sensor.
●Do not attach accessories or stickers to the sensor, grille cover or surrounding
area.
●Do not modify or paint the sensor and grille cover.
●Do not replace them with non-genuine parts.

Intuitive parking assist
: If equipped
Intuitive parking assist uses sensors in the front and rear of the vehicle to
detect the distance between the vehicle and any obstacles, and informs the
driver of this distance using the multi-information display, the touch screen,
and warning beeps.
The system may be used at speeds less than about 6 mph (10 km/h).
■Sensor types
Dual sensors
There are 4 sensors installed in the front bumper, two in the center section
to detect obstacles directly ahead, and one in each corner of the bumper,
to detect obstacles in those areas.
The dual sensors detect obstacles ahead of the vehicle, and judge whether
avoidance maneuvers are necessary (whether the obstacle will come
within 0.8 ft. [25 cm] of the vehicle), according to the distance between
the obstacle and the vehicle, and the steering wheel position. The screen
display and beeps will change accordingly.
Rear corner sensors
These sensors detect obstacles around the rear corners of the vehicle.
Back sensors
These sensors detect obstacles behind the vehicle.

■Intuitive parking assist switch
Press the switch to turn the
system on/off.
If the intuitive parking assist is
turned on, the indicator light will
come on, and the system will
operate under the following
conditions:
• The dual sensors will oper-
ate if the shift lever is in a
position other than “R” or
“P”.
• All corner sensors and the
back sensors will operate if
the shift lever is in “R”.

Multi-information display and touch screen
If the sensors detect an obstacle, it is displayed on the multi-information
display in the instrument cluster.
You can change the conditions under which information is displayed on
the touch screen. (P. 2 4 5 )

Sensor detection display, obstacle distance and beeps
When the intuitive parking assist is activated, the approximate distance to
the obstacle is displayed. Also, if an obstacle with which a collision is pos-
sible is detected, a warning beep will sound.
■Dual sensor
• If the shift lever is in “R”, only the corner sensors will detect obstacles.
