control mode, the vehicle automatically accelerates and decelerates in accor-
dance to the changes in speed of the pr eceding vehicle. In constant speed con-
trol mode, the vehicle runs at a fixed speed.

automatically to long mode when the
power switch is turned to 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.Changing the vehicle-to-vehicle distance (vehicle-to-vehicle distance

NX300h_U_OM78007U Pulling the lever toward you cancels
the speed control. The speed setting is also canceled when
the brake pedal is depressed.
Pushing the lever up resumes the
speed control and returns vehicle
speed to the set speed. However, when a vehicle ahead is not detected in vehicle-to-vehicle distance control
mode, cruise control does not resume when the actual vehicle speed is approximately
25 mph (40 km/h) or less. Also, when the vehicle is in constant speed control mode
and the actual vehicle speed is approximately 25 mph (40 km/h) or less, cruise con-
trol does not resume as the set speed is cleared.
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 pedalCanceling and resuming the speed control 1

Dynamic radar cruise control can be set when ●
The shift lever is in D or range 4 or higher of S has been selected.●
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. “Radar Cruise Control Unavailable” will be displayed on the multi-information
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 can not properly detect the vehicle.●
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 correctly because it is covered in some way. ●
The windshield wipers are oper ating at high speed (when the wiper switch is set to the
“AUTO” mode or the high speed wiper operation position). ●
Pre-collision braking is activated.
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 automatica lly 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 by pressing the VSC OFF switch. ●
Pre-collision braking 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 is cancel ed if an obstruction is detected.
