■Dynamic radar cruise can be set when
●The shift lever is in D. (Recommended)
Dynamic radar cruise control can also be set when the shift lever is in the S posi-
tion and range 4, 5 or 6 has been selected.
●Vehicle speed is above approximately 30 mph (50 km/h).
■Switching modes
The mode cannot be switched to constant speed control mode if vehicle-to-vehicle
distance control mode has been used. The mode also cannot be switched from
constant speed control to vehicle-to-vehicle distance control mode. Turn the sys-
tem off by pressing the “ON-OFF” button, and turn it on again.
■Accelerating
The vehicle can be accelerated normally. However, during vehicle-to-vehicle dis-
tance control mode, the vehicle speed may decrease below the set speed in order
to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the follow-
ing situations:
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The sensor cannot operate correctly because it is covered in some way.
●The windshield wipers are operating at high speed.
●The driving mode is set to second start mode.
●Bad weather causes the detection function to become extremely unstable.
●Multi-terrain mode is selected other than OFF.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

■Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situations:
●Actual vehicle speed is more than approximately 10 mph (16 km/h) below the
set vehicle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed falls below approximately 25 mph (40 km/h).
●VSC is activated.
●The center differential lock/unlock is not completed within 5 seconds while the
dynamic radar cruise control system is on.
■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.
■Warning lights and messages for dynamic radar cruise control
Warning lights and messages are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. (→P. 6 9 8 )
Distance optionsVehicle-to-vehicle distance

CAUTION
■To avoid inadvertent cruise control activation
Switch the cruise control off using the “ON-OFF” button when not in use.
■Situations unsuitable for the 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
●At entrances to expressways
●When weather conditions are bad enough that they may prevent the sensors
from functioning correctly (fog, snow, sandstorm, etc.)
●When a buzzer is heard often
●When towing a trailer or emergency towing
●In traffic conditions where the vehicle is repeatedly sped up and slowed down at
frequent intervals

CAUTION
■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. 254) 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
■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 fatal or serious 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 luggage
compartment 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
●Excessive exhaust gas (black smoke) is coming from the vehicle ahead or other
vehicles around you, obscuring your front view
●The rear section of the vehicle ahead is extremely dirty
●The vehicle ahead has higher ground clearance

CAUTION
■To ensure the sensor functions correctly
Do not do the following to the sensor or grille as doing so may cause the sensor not
to function correctly and could result in an accident:
●Sticking or attaching anything to them
●Leaving them dirty
●Disassembling or subjecting them to strong shocks
●Modifying or painting them
●Replacing them with non-genuine parts
■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 your 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.

The distance from your vehicle to nearby obstacles when parallel parking
or maneuvering into a garage is measured by the sensors and communi-
cated via the multi-information display and a buzzer. Always check the sur-
rounding area when using this system.

Buzzer operation and distance to an obstacle
A beep sounds when the corner sensors and center sensors are operat-
ing.
● The buzzer beeps faster as the vehicle approaches an obstacle.
When the vehicle comes within the fo llowing distance of the obstacle,
the buzzer sounds continuously.
• Front corner sensors: Approximately 1.1 ft. (35 cm)
• Front center sensors: Approximately 1.0 ft. (30 cm)
• Rear corner sensors: Approximately 0.8 ft. (25 cm)
• Rear center sensors: Approximately 1.3 ft. (40 cm)
● When 2 or more obstacles are detected simultaneously, the buzzer
system responds to the nearest obstacle.
