tance control mode operates properly. (Some obstructions, such as snow, ice and plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is cancel ed if an obstruction is detected.

Dynamic radar cruise control with full-speed
range
Without accelerator pedal operation by the driver, in vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates, decelerates and stops in
accordance to the changes in speed of th e preceding vehicle. In constant speed
control mode, the vehicle runs at a fixed speed.
Use the dynamic radar cruise control with full-speed range on freeways and
highways.

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.
Accelerate or decelerate, with
accelerator pedal operation, to the
desired vehicle speed (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 be comes the set speed.
While the vehicle is in vehicle-to-vehicle distance control mode, if the lever is released
when vehicle speed is less than 30 mph (50 km/h) and a vehicle ahead can be
detected, the vehicle will start following th e vehicle ahead at a set speed of 30 mph
(50 km/h).

Pressing the button changes the vehi-
cle-to-vehicle distance as follows: Long
Medium
Short
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 (8 0 km/h). Vehicle-to-vehicle distance
increases/decreases in accordance with vehicle speed. When the vehicle is
stopped by system control, the vehicle-to-vehicle distance will be about 10 ft.
(3 m) to 16 ft. (5 m) regardless of the vehicle-to-vehicle distance setting.

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, there is a po ssibility that the warnings will not occur:
●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

■Dynamic radar cruise control with full-speed range can be set when
●The shift lever is in D.
●Vehicle speed is above 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.
■Automatic cancelation of vehicle- to-vehicle distance control mode
Vehicle-to-vehicle distance control mode is automatically canceled in the following situ-
ations:
●VSC is activated.
●TRAC is activated for a period of time.
●When the VSC or TRAC system is turned off by pressing the VSC OFF switch.
●The sensor cannot detect properly beca use it is obstructed in some way.
●Brake automatically operated for long peri ods of time, such as traffic jams, etc.
●The parking brake is operated.
●The vehicle is stopped by system control on a steep incline.
●Pre-collision braking is activated.
●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 back door or hood is opened.
When vehicle-to-vehicle distance control mo de is automatically canceled in the follow-
ing situations, “Radar Cruise Control Unavaila ble” will be displayed on the multi-infor-
mation display:
●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
below 25 mph (40 km/h). Otherwise, the se nsor cannot properly detect the vehicle.
●The windshield wipers are operating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position).
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.

■Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-vehicle dis-
tance control mode operates properly. (Some obstructions, such as snow, ice and plastic
objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control with full-speed range is canceled if an obstruction is
detected.
■Warning messages and buzzers for dynamic ra dar 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

erating the vehicle to the desired speed and then pushing the lever down to set the new
speed.
■Automatic cancelation of cruise control
