■Vehicle-to-vehicle distance settings
Select a distance from the table below. Note that the distances shown correspond
to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance increases/
decreases in accordance with vehicle speed.
■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle
distance control operates properly. (Some obstructions, such as snow, ice or plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■Approach warning
In the following instances, there is a po ssibility that the warnings will not occur:
●When the speed of the vehicle ahead ma tches or exceeds your vehicle’s speed
●When the vehicle ahead is traveling at an extremely slow speed
●Immediately after the cruise control speed has been set
●At the instant the accelerator is applied

CAUTION
■Before using dynamic radar cruise control
Do not overly rely on vehicle-to-vehicle distance control.
Be aware of the set vehicle speed. If au tomatic deceleration/acceleration is not
appropriate, adjust the vehicle speed, as well as the distance between your vehicle
and vehicles ahead by applying the brakes, etc.
■To avoid operating the dynamic radar cruise control by mistake
Keep the “ON-OFF” button off when not in use.
■Situations unsuitable for dynamic radar cruise control
Do not use dynamic radar cruise contro l in any of the following situations.
Doing so may result in inappropriate co ntrol of speed and could cause serious or
fatal accident.
●In heavy traffic
●On roads with sharp bends
●On winding roads
●On slippery roads, such as thos e covered with rain, ice or snow
●On steep downhills, 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 (f og, snow, sandstorm, etc.)
●When the approach warning buzzer can be heard often

CAUTION
■When the radar 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 prox-
imity alarm (→ P. 525) will not be activated, and a serious or fatal accident may
result.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving
●Vehicles with small rear ends (tra ilers with no load on board etc.)
●Motorcycles traveling in the same lane
■Conditions under which the vehicle-to-vehicle distance control may not function
correctly
Apply the brakes as necessary in the foll owing 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

CAUTION
■To ensure the radar sensor functions correctly
Do not do the following to the sensor or grille cover as doing so may cause the sen-
sor not to function correctly and could result in a serious or fatal accident.
●Stick or attach anything to them
●Leave them dirty
●Disassemble, subject them to strong shocks
●Modify or paint them
●Replace them with non-genuine parts
■Handling the radar sensor
Observe the following to ensure the cruise control system can function effectively.
●Keep the sensor and front grille clean at all times.
Clean the sensor and front grille 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 or surrounding area.
●Do not modify or paint the sensor and grille.

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 mult i-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, an d 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 vehicl e), 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”.
