Press the “ON/OFF” button to acti-
vate the cruise control.
Radar cruise control indicator will come
on and a message will be displayed on
the multi-information display.
Press the button again to deactivate the
cruise control.
If the “ON/OFF” button is pressed and
held for 1.5 seconds or more, the system
turns on in constant speed control
mode. (
Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (at or above
approximately 30 mph [50 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

Pressing the switch changes the vehicle-to-vehicle distance as follows:
Long
Medium

The vehicle-to-vehicle distance is set automatically to long mode when the engine
switch is turned to IGNITION ON mode.
If a vehicle is running ahead of you, the preceding vehicle mark will also be displayed.
Select a distance from the table below. Note that the distances shown corre-
spond to a vehicle speed of 50 mph (80 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle stops at a certain vehicle-to-vehicle dis-
tance depending on the situation.

After the vehicle ahead of you starts off,
push the lever up.
Your vehicle will also resume follow-up
cruising if the accelerator pedal is
depressed after the vehicle ahead of
you starts off.
Pulling the lever toward you cancels
the speed control.
The speed control is also canceled when
the brake pedal is depressed.
(When the vehicle has been stopped by
system control, depressing the brake
pedal does not cancel the setting.)
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
However, when a vehicle ahead is not detected, cruise control does not resume when
the vehicle speed is approximately 25 mph (40 km/h) or less.
When your vehicle is too close to a
vehicle ahead, and sufficient automatic
deceleration via the cruise control is
not possible, the display will flash and
the buzzer will sound to alert the driver.
An example of this would be if another
driver cuts in front of you while you are
following a vehicle. Depress the brake
pedal to ensure an appropriate vehicle-
to-vehicle distance.

Warnings may not occur when
In the following instances, warnings may not occur even when the vehicle-to-
vehicle distance is small.
●
When the speed of the preceding vehicle matches or exceeds your vehicle
speed
●
When the preceding vehicle is traveling at an extremely slow speed
●
Immediately after the cruise control speed was set
●
When depressing the accelerator pedal
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 30 mph [50 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.
●
Range 4 or higher of D has been selected by using the paddle shift switch.
●
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 at or 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.
●
TRAC is activated for a period of time.
●
When the VSC or TRAC system is turned off.
●
When snow 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
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.
●
TRAC is activated for a period of time.
●
When the VSC or TRAC system is turned off.
●
Pre-collision braking is activated.
If constant speed control mode is automatically canceled for any other reason, there may
be a malfunction in the system. Contact your Lexus dealer.
■
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. 265) 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
●
When your vehicle is pointing upwards
(caused by a heavy load in the luggage com-
partment, etc.)

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
●
Preceding vehicle has an extremely high
ground clearance
●
When the road curves or when the lanes are
narrow
