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 a dirty radar sensor, etc.
With the cruise control off, press and
hold the “ON/OFF” button for 1.5
seconds or more.
Immediately after the “ON/OFF” but-
ton is pressed, the radar cruise control
indicator will come on. Afterwards, it
switches to the cruise control indicator.
Switching to constant speed control
mode is only possible when operating
the lever with the cruise control off.
Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 25 mph [40 km/h])
and push the lever down to set the
speed.
Cruise control “SET” indicator will come
on.
The vehicle speed at the moment the
lever is released becomes the set speed.

■
Dynamic radar cruise control with full-speed range 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 switch (vehicles with
paddle shift switches).
●
Vehicle speed is at or above approximately 30 mph (50 km/h).
However, when a preceding vehicle is detected, the dynamic radar cruise control with
full-speed range can be set even if the vehicle speed is below approximately 30 mph
(50 km/h).
■
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.
■
When the vehicle stops while follow-up cruising
●
Pushing the lever up while the vehicle ahead stops will resume follow-up cruising if the
vehicle ahead starts off within approximately 3 seconds after the lever is pushed up.
●
If the vehicle ahead starts off within 3 seconds after your vehicle stops, follow-up cruis-
ing will be resumed.
■
Automatic cancelation of vehicle-to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●
Actual vehicle speed falls below approximately 25 mph (40 km/h) when there are no
vehicles ahead.
●
The preceding vehicle leaves the lane when your vehicle is following at a vehicle speed
at or below approximately 25 mph (40 km/h). Otherwise, the sensor can not properly
detect the vehicle. (“CRUISE NOT AVAILABLE No Preceding Vehicles” is displayed
on the multi-information display)
●
VSC is activated.
●
Active TRAC is activated for a period of time.
●
When the VSC or Active TRAC system is turned off.
●
When second start mode is set.
●
The sensor cannot detect correctly because it is covered in some way.
●
Pre-collision braking is activated.
●
The parking brake is operated.
●
The vehicle is stopped by system control on a steep incline.
●
The following are detected when the vehicle has been stopped by system control:
• The driver is not wearing a seat belt.
• The driver’s door is opened.
• The vehicle has been stopped for about 3 minutes
●
The switching operation continues for 5 seconds or more after the center differential
lock switch has been operated.
If vehicle-to-vehicle distance control mode is automatically canceled for any other rea-
son, there may be a malfunction in the system. Contact your Lexus dealer.

■
Automatic cancelation of constant speed control mode
Constant speed control mode is automatically canceled in the following situations:
●
Actual vehicle speed is more than approximately 10 mph (16 km/h) below the set vehi-
cle speed.
●
Actual vehicle speed falls below approximately 25 mph (40 km/h).
●
VSC is activated.
●
Active TRAC is activated for a period of time.
●
When the VSC or Active TRAC system is turned off.
●
Pre-collision braking is activated.
●
The switching operation continues for 5 seconds or more after the center differential
lock switch has been operated.
If constant speed control mode is automatically canceled for any other reason, there may
be a malfunction in the system. Contact your Lexus dealer.
■
Brake system operation sound
If the brakes are applied automatically while the vehicle is in vehicle-to-vehicle distance
control mode, a brake system operation sound may be heard. This does not indicate a
malfunction.
■
Warning messages and buzzers for dynamic radar cruise control with full-speed range
Warning messages and buzzers are used to indicate a system malfunction or to inform
the driver of the need for caution while driving. If a warning message is shown on the
multi-information display, read the message and follow the instructions.
■
When the sensor may not be correctly detecting the vehicle ahead
In the case of the following and depending on the conditions, operate the brake pedal
when deceleration of the system is insufficient or operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to correctly detect these types of vehicles, the approach
warning (
P. 282) may not be activated.
●
Vehicles that cut in suddenly
●
Vehicles traveling at low speeds
●
Vehicles that are not moving in the same lane
●
Vehicles with small rear ends (trailers with no load on board, etc.)
●
Motorcycles traveling in the same lane
●
When water or snow thrown up by the surrounding vehicles hinders the detecting of
the sensor

■
Conditions under which the vehicle-to-vehicle distance control mode may not function
correctly
In the case of the following conditions, operate the brake pedal (or accelerator pedal,
depending on the situation) as necessary.
As the sensor may not be able to correctly detect vehicles ahead, the system may not
operate properly.
●
When the vehicle ahead of you decelerates suddenly
●
When driving on a road surrounded by a structure, such as in a tunnel or on a bridge
●
While the vehicle speed is decreasing to the set speed after the vehicle accelerates by
depressing the accelerator pedal
●
When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)
●
Preceding vehicle has an extremely high
ground clearance
●
When the road curves or when the lanes are
narrow
●
When steering wheel operation or your posi-
tion in the lane is unstable

Buzzer operation and distance to an obstacle
A buzzer sounds when the sensors are operating.
●
The buzzer sounds faster as the vehicle approaches an obstacle.
When the vehicle comes within the following distance of the obstacle, the
buzzer sounds continuously.
• Front center sensors: Approximately 1.1 ft. (35 cm)
• Corner: Approximately 1.1 ft. (35 cm)
• Rear center sensors: Approximately 1.6 ft. (50 cm)
●
When 2 or more obstacles are detected simultaneously, the buzzer system
responds to the nearest obstacle. If one or both come within the above dis-
tances, the beep will repeat a long tone, followed by fast beeps.
●
You can change the volume of the warning beeps. (

Sensor detection information
●
The sensor’s detection areas are limited to the areas around the vehicle’s bumper.
●
Certain vehicle conditions and the surrounding 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 the 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 considerably 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 (lowered 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.
