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.

To change the set speed, operate the lever until the desired set speed is
displayed.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily move
the lever in the desired direction.
Large adjustment: Hold the lever in
the desired direction.
In the vehicle-to-vehicle distance control mode, the set speed will be increased or
decreased as follows:
Fine adjustment: By approximately 1 km/h (0.6 mph) each time the lever is oper-
ated
Large adjustment: By approximately 5 km/h (3.1 mph) for each 0.75 seconds the
lever is held
In the constant speed control mode ( P. 320), the set speed will be increased or
decreased as follows:
Fine adjustment: By approximately 1.6 km/h (1 mph) each time the lever is oper-
ated
Large adjustment: The set speed can be increased or decreased continually until
the lever is released.

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 cor-
respond to a vehicle speed of 80 km/h (50 mph). Vehicle-to-vehicle dis-
tance increases/decreases in accordance with vehicle speed.

Pulling the lever toward you can-
cels the cruise control.
The speed setting is also canceled
when the brakes are applied.
Pushing the lever up resumes the
cruise control and returns vehicle
speed to the set speed.
Resuming is available when the vehi-
cle speed is more than approximately
40 km/h (25 mph).

3184-5. Using the driving support systems
LS460/LS460L_GE (OM50G06E)
This mode employs a radar sensor to detect the presence of vehicles up to
approximately 120 m (400 ft.) ahead, determines the current 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.
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 automatically decel-
erates 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.

Driving

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.
