●The shift lever is in the D or range 4 or higher of S has been selected.
(vehicles without paddle shift switches)
●The shift lever is in D.
(vehicles with paddle shift switches)
●Range 4 or higher of D has been selected by using the paddle shift.

●Vehicle speed is above approximately 40 km/h (25 mph).
■Accelerating after setting the vehicle speed
●The vehicle can be accelerated normally. After acceleration, the set speed
resumes.
●Even without canceling the cruise control, the set speed can be increased by first
accelerating the vehicle to the desired speed and then pushing the lever down to
set the new speed.
■Automatic cruise control cancelation
Cruise control will stop maintaining the vehicle speed in any of the following situa-
tions.
●Actual vehicle speed falls more than approximately 16 km/h (10 mph) below the
preset vehicle speed.
At this time, the memorized set speed is not retained.
●Actual vehicle speed is 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.
■If the warning message for the cruise control is shown on the multi-information dis-
play
Press the “ON•OFF” button once to deactivate the system, and then press the but-
ton again to reactivate the system.
If the cruise control speed cannot be set or if the cruise control cancels immediately

Dynamic radar cruise control supplements conventional cruise control
with a vehicle-to-vehicle distance co ntrol. In vehicle-to-vehicle distance
control mode, the vehicle automatically accelerates or decelerates in
order to maintain a set following distance from vehicles ahead.

Example of follow-up cruising
When following a vehicle driving slower than the set speed
The system continues follow-up cruising while adjusting for changes in the speed
of the vehicle ahead in order to maintain the vehicle-to-vehicle distance set by the
driver.
Example of acceleration
When there are no longer any vehicles ahead driving slower than the
set speed
The system accelerates until the set speed is reached. The system then returns to
constant speed cruising.
When your vehicle is too close to a vehicle ahead, and sufficient auto-
matic 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. Apply the brakes to ensure an appropriate vehicle-to-vehicle dis-
tance.
■Warnings may not occur when
In the following instances, there is a possibility that the warnings will not
occur:
●When the speed of the vehicle ahead matches or exceeds your vehi-
cle speed
●When the vehicle ahead is traveling at an extremely slow speed
●Immediately after the cruise control speed was set
●At the instant the accelerator is applied

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 func-
tion correctly due to dirt etc.
Press the “ON•OFF” button to
activate the cruise control.
Radar cruise control indicator will
come on.
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 control mode, push the lever
forward again and hold for approxi-
mately 1 second.
After the desired speed has been set,
it is not possible to return to vehicle-
to-vehicle distance control mode.
If the engine switch is turned off and
then turned to IGNITION ON mode
again, the vehicle will automatically
return to vehicle-to-vehicle distance
control mode.

■Dynamic radar cruise control can be set when
●The shift lever is in the D or range 4 or higher of S has been selected.
(vehicles without paddle shift switches)
●The shift lever is in D.
(vehicles with paddle shift switches)
●Range 4 or higher of D has been selected by using the paddle shift.
(vehicles with paddle shift switches)
●Vehicle speed is above approximately 50 km/h (30 mph).
■Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed may
decrease below the set speed in order to maintain the distance to the vehicle ahead.
■Automatic cancelation of vehicle -to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the following
situations:
●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 operate correctly because it is covered in some way.
●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).
●When snow mode is set.
If vehicle-to-vehicle distance control driving is automatically canceled for any other
reason, there may be a malfunction in the system. Contact your Lexus dealer.

objects, cannot be detected by the obstruction sensor.)
Dynamic radar cruise control is canceled if an obstruction is detected.
■Warning messages and buzzers for dynamic radar cruise control
Warning messages and buzzers are used to indicate a system malfunction or to
