When constant speed control mode is selected, your vehicle will maintain a set
speed without controlling the vehicle-to-vehicle distance. Select this mode only
when vehicle-to-vehicle distance control mode does not function correctly due
to dirt, etc.
Press the “ON/OFF” button to acti-
vate the cruise control.
Press the button again to deactivate the cruise control.
Switch to constant speed control
mode.
(Push the lever forward and hold for
approximately 1 second.)
Cruise control indicator will come on.
When in constant speed control mode, to return to vehicle-to-vehicle distance con- trol mode, push the lever forward again and hold for approximately 1 second.
After the desired speed has been set, it is not possible to return to vehicle-to-vehicle distance control mode.
If the power switch is turned off and then turned to ON mode again, the vehicle will
automatically return to vehicle-to-vehicle distance control mode.
Adjusting the speed setting: P. 260
Canceling and resuming the speed setting: P. 262
■Dynamic radar cruise control can be set when
●The shift lever is in D or range 4 or higher of S has been selected.
●Range 4 or higher of D has been selected by using the paddle shift.
●Vehicle speed is above approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate by operating the accelerator pedal. After accelerating, the set speed resumes. However, during vehicle-to-vehicle distance control mode, the vehi-cle speed may decrease below the set speed in order to maintain the distance to the pre-
ceding vehicle.

■Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance co ntrol driving is automatically canceled in the following situ- ations:
●Actual vehicle speed falls below approximately 40 km/h (25 mph).
●VSC is activated.
●TRC is activated for a period of time.
●When the VSC or TRC system is turned off by pressing the VSC OFF switch.
●The sensor cannot detect correctly because it is covered in some way.

When the inside of both lane lines turn
white:
Indicates that both right and left lane
markers are recognized.
If the vehicle deviates from the lane, the
lane line on the side the vehicle has devi- ated from will flash in yellow. ( P. 543)
When the inside of either lane line turns
white:
Indicates that the lane marker on the
white-marked side is recognized.
If the vehicle deviates from the side of a
lane with recognized lane markers, the lane line will flash in yellow. ( P. 543)
When the inside of both lane lines are
black:
Indicates that no lane markers are rec-
ognized or the LDA system is tempo-
rarily canceled.

■Temporary cancelation of the LDA system functions
If any of the following occurs, the LDA system functions will be temporarily canceled. The functions will resume after the necessary operating conditions have returned.
●The turn signal lever is operated.
●The vehicle speed deviates from the operating range of the LDA system functions.
●When the lane lines cannot be recognized while driving.
●When the lane departure warning sounds.
The lane departure warning function will not operate again for a several seconds after it has been activated, even if the vehicle leaves the lane again.
■The lane departure warning
Depending on the audio system sound level or air conditioning fan noise while the audio system or air conditioning system is in use, it may be difficult to hear the warning sound.
■After the vehicle has been parked in the sun
The LDA system may not be available and a warning message ( P. 548) will be dis- played for a while after driving has started. When the temperature in the cabin decreasesand the temperature around the camera sensor ( P. 273) becomes suitable for its
operation, the functions will begin to operate.
■If there are lane markers on only one side of the vehicle
The lane departure warning will not operate fo r the side on which lane markers could not
be recognized.
■Conditions in which the function may not operate correctly
In the following situations, the camera sensor may be unable to recognize lane markers
causing the lane departure warning function to operate incorrectly. However, this does not indicate a malfunction.
●When driving through an area with no lane markers, such as a tollbooth, a crossing or
before a ticket checkpoint
●When driving on a sharp curve
●When lane markers are extremely narrow or extremely wide
●When the vehicle leans to one side an unusual amount due to a heavy load or improper tire inflation pressure
●When the following distance between your vehicle and the vehicle ahead is extremely
short
●When the lane markers are yellow (These ma y be more difficult for the system to rec- ognize compared to white markers.)
●When the lane markers are broken, Botts’ dots (raised pavement markers) or stones
●When the lane markers are on a curb etc.
●When lane markers are obscured or partially obscured by sand, dirt, etc.
●When there are shadows on the road running parallel with lane markers, or if a shadow covers the lane markers
●When driving on a partic ularly bright road surface, such as concrete
●When driving on a road surface that is bright due to reflected light
●When driving in a location where the light level changes rapidly, such as the entrance to
or exit from a tunnel

: If equipped
Vehicles with a Lexus Display Audio system:
The distance from your vehicle to ne arby obstacles when parallel parking or
maneuvering into a garage is measured by the sensors and communicated via
the multi-information display, Lexus Display Audio screen and a buzzer.
Always check the surrounding ar ea when using this system.
Vehicles with a navigation or multimedia system:
Refer to the “NAVIGATION AND MULTIMEDIA SYSTEM OWNER’S
MANUAL”.

WARNING
●The shape of an object may prevent the sensor from detecting it. Pay particular atten- tion to the following:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves • Sharply-angled objects•Low objects
• Tall objects with upper sections projecting outwards in the direction of your vehi- cle• People, animals and other moving objects
• People wearing certain types of clothing
●The following situations may occur when using the Lexus parking assist-sensor.
• Depending on the shape of the object and other factors, the detection distance may be shortened, or detection may not be possible.• Objects may not be detected if they are too close to a sensor.
• There will be a short delay between the de tection of an object and display of the detection. Even at slow speeds, there is a possibility that the object will come within a sensor’s detection area before the display is shown and a warning beep
sounds. • Thin posts or objects lower than a sensor may not be detected when approached,even if they have been detected once.
• It might be difficult to hear beeps due to the volume of the audio system or air flow noise of the air conditioning system.
NOTICE
■When using Lexus parking assist-sensor
In the following situations, the system may not function correctly due to a sensor mal-
function etc. Have the vehicle checked by any authorized Lexus dealer or repairer, or another duly qualified and equipped professional.
●The Lexus parking assist-sensor operation display flashes, and a beep sounds when
no obstacles are detected.
●If the area around a sensor collides with something, or is subjected to strong impact.
●If the bumper or grille collides with something.
●If the display shows continuously without beeping, except when the switch has been turned on.
●If a display error occurs, first check the sensor.
If the error occurs even when there is no ice, snow or mud on the sensor, it is likely that the sensor is malfunctioning.
■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.
