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.
Vehicle-to-vehicle distance settings

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.

When driving
CT200h_OM_OM76067E_(EE)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.
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.
