Driving in vehicle-to-vehicle distance control mode
This mode employs a radar sensor to detect the presence of vehi-
cles up to approximately 120 m (400 ft.) ahead, determines the cur-
rent vehicle-to-vehicle following distance, and operates to
maintain a suitable following distance from the vehicle ahead.
Note that vehicle-to-vehicle distance will close in when traveling on
long downhill slopes.

CT200h_EE (OM76041E)Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver. The desired vehicle-
to-vehicle distance can also be set by operating the vehicle-to-vehicle
distance control.
Example of deceleration cruising
When the vehicle ahead is driving slower than the set speed
When a vehicle is detected running ahead of you, the system automat-
ically decelerates your vehicle. When a greater reduction in vehicle
speed is necessary, the system applies the brakes. A warning tone
warns you when the system cannot decelerate sufficiently to prevent
your vehicle from closing in on the vehicle 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.

Approach warning
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. Apply the brakes to ensure an
appropriate vehicle-to-vehicle distance.
Warnings may not occur when
In the following instances, there is a possibility that the warn-
ings will not occur:
When the speed of the vehicle ahead matches or exceeds your
vehicle 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

Selecting conventional constant speed control mode
Constant speed control mode differs from vehicle-to-vehicle dis-
tance control mode. When constant speed control mode is selected,
your vehicle will maintain a set speed regardless of whether or not
there are other vehicles in the lane ahead.
Press the “ON-OFF” button
to activate the cruise control.
Radar cruise control indicator
will come on.
Press the button again to deacti-
vate the cruise control.
Switch to constant speed
control mode.
(Push the lever forward and
hold for approximately one
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 approximately 1
second.

After the desired speed has been
set, it is not possible to return to
vehicle-to-vehicle distance con-
trol mode.
If the “POWER” switch is
turned off and then turned to
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 position is in D.
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 dis-
tance to the vehicle ahead.
Set speed
The set speed may be unsustainable depending on driving circumstances.
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.
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).
If vehicle-to-vehicle distance control driving is automatically canceled for
any other reason, there may be a malfunction in the system. Contact any
authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following
situations:
Actual vehicle speed is more than approximately 16 km/h (10 mph)
below the set vehicle speed.
At this time, the memorized set speed is not retained.
Vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
Radar sensor and grille cover
Always keep the sensor and grille cover clean to ensure that the vehicle-to-
vehicle distance control operates properly. (Some obstructions, such as
snow, ice and plastic 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 inform the driver of the need for caution while driving.
