DISTANCE CONTROL ASSIST OP-
ERATION
Always pay attention to the operation of
the vehicle and be ready to manua lly
decelerate to maintain the proper following
distance. The Distance Control Assist (DCA)
system may not be able to decelerate the
vehicle under some circumstances.
The DCA system uses a sensor
*
A
located
on the front of the vehicle to detect
vehicles traveling ahead. The sensor gen-
erally detects the signals returned from the
reflectors on a vehicle ahead. Therefore, if
the sensor cannot detect the reflector on
the vehicle ahead, the DCA system may not
operate.
The following are some conditions in which
the sensor cannot detect the signals:
. When the reflector of the vehicle ahead
is positioned high on the vehicle
(trailer, etc.)
. When the reflector on the vehicle ahead
is missing, damaged or covered
. When the reflector of the vehicle ahead
is covered with dirt, snow and road
spray
. When the snow or road spray from
traveling vehicles reduces the sensor’s
visibility
. 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 automati-
cally check the sensor’s operation. When
the sensor is covered with dirt or is
obstructed, the system will automatically
be canceled. If the sensor is covered with
ice, a transparent or translucent vinyl bag,
etc., the DCA system may not detect them.
In these instances, the Distance Control
Assist (DCA) system may not be able to
decelerate the vehicle properly. Be sure to
check and clean the 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 necessary and if the vehicle
ahead comes to a stop, the vehic le
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 laneahead
or if a veh icle traveling ahead rapidly
decelerates, the distance between 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” later in this
section.
This system only brakes and moves the
accelerator 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
