DISTANCE CONTROL ASSIST
OPERATION
Always pay attention to the operation of the ve-
hicle and be ready to manually decelerate to
maintain the proper following distance. The Dis-
tance Control Assist (DCA) system may not be
able to decelerate the vehicle under some cir-
cumstances.
The DCA system uses a sensor
䊊
A
located be-
hind the front bumper 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 vehicle ahead, the DCA sys-
tem may not operate.
The following are some conditions in which the
sensor cannot detect the signals:
●
When the reflector of the vehicle ahead is
covered with dirt, snow and road spray
●
When dense exhaust or other smoke (black
smoke) from vehicles reduces the sensor’s
visibility
●
When excessively heavy baggage is loaded
in the rear seat or the luggage room of your
vehicle
The DCA system is designed to automatically
check the sensor’s operation. When the front
bumper area of the distance sensor is covered
with dirt or is obstructed, the system will auto-
matically cancel. If the front bumper area of the
distance sensor is covered with ice, a transparent
or translucent vinyl bag, etc., the DCA 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 se-
lected following distance from the vehicle ahead.
Be sure to check and clean the front bumper area
of the distance sensor regularly.
The DCA system is designed to help assist the
driver to maintain a following distance from the
vehicle ahead. The system will decelerate as nec-
essary and if the vehicle ahead comes to a stop,
the vehicle decelerates to a standstill. However,
the DCA system can only apply up to 25% of the
vehicles total braking power. If a vehicle moves
into the traveling lane ahead or if a vehicle travel-
ing ahead rapidly decelerates, the distance be-
tween vehicles may become closer because the
DCA system cannot decelerate the vehicle
quickly enough. If this occurs, the DCA system
will sound a warning chime and blink the system
display to notify the driver to take necessary
action.
See “Approach warning” in this section.
This system only brakes and moves the accelera-
tor pedal upward to help assist the driver to
maintain a following distance from the vehicle
ahead. Acceleration should be operated by the
driver.
The DCA 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.
