The vehicle-to-vehicle distance control mode
uses a sensor
䊊
A
located behind the front bum-
per of the vehicle to detect vehicles traveling
ahead. The sensor generally detects the signals
returned from the vehicle ahead. Therefore, if the
sensor cannot detect the reflection from the ve-
hicle ahead, the ICC system may not maintain the
selected distance.
The following are some conditions in which the
sensor cannot detect the signals:
●
When the snow or road spray from traveling
vehicles reduces the sensor’s visibility
●
When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The ICC system is designed to automatically
check the sensor’s operation within the limitation
of the system. When the front bumper area of the
distance sensor is covered with dirt or is ob-
structed, the system will automatically cancel. If
the front bumper area of the distance sensor is
covered with ice, a transparent or translucent
vinyl bag, etc., the ICC system may not detect
them. In these instances, the vehicle to vehicle
distance control mode may not cancel and may
not be able to maintain the selected following
distance from the vehicle ahead. Be sure to
check and clean the front bumper area of the
distance sensor regularly.
The vehicle-to-vehicle distance control mode is
designed to maintain a selected distance and
reduce the speed to match the slower vehicle
ahead. The system will decelerate the vehicle as
necessary and if the vehicle ahead comes to a
stop, the vehicle decelerates to a standstill. How-
ever, the ICC system can only apply up to 25% of
the vehicles total braking power. This system
should only be used when traffic conditions allow
vehicle speeds to remain fairly constant or when
vehicle speeds change gradually. If a vehicle
moves into the traveling lane ahead or if a vehicle
traveling ahead rapidly decelerates, the distance
between vehicles may become closer because
the ICC system cannot decelerate the vehicle
quickly enough. If this occurs, the ICC system will
sound a warning chime and blink the system
display to notify the driver to take necessary
action.
The system will cancel and a warning chime will
sound if the speed is below approximately
15 MPH (24 km/h) and a vehicle is not detected
ahead. The system will also disengage when the
vehicle goes above the maximum set speed.
See “Approach warning” later in this section.
The following items are controlled in the vehicle-
to-vehicle distance control mode:
●
When there are no vehicles traveling ahead,
the
vehicle-to-vehicle
distance
control
mode maintains the speed set by the driver.
The set speed range is between approxi-
mately 20 and 90 MPH (32 and 144 km/h).
●
When there is a vehicle traveling ahead, the
vehicle-to-vehicle distance control mode
adjusts the speed to maintain the distance,
selected by driver, from the vehicle ahead.
The adjusting speed range is up to the set
speed. If the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill within
the limitations of the system. The system will
cancel once it judges a standstill with a
warning chime.
●
When the vehicle traveling ahead has moved
out from its lane of travel, the vehicle-to-
vehicle distance control mode accelerates
and maintains vehicle speed up to the set
speed.
The ICC system does not control vehicle speed
or warn you when you approach stationary and
slow moving vehicles. You must pay attention to
vehicle operation to maintain proper distance
from vehicles ahead when approaching toll gates
or traffic congestion.
