• The detection zone of the sensor is limited. A vehicle ahead must
be in the detection zone for the system to operate.
- A vehicle ahead may move outside of the detection zone due to its
position within the same lane of travel. Motorcycles may not be
detected in the same lane ahead if they are traveling offset from
the center line of the lane. A vehicle that is entering the lane ahead
may not be detected until the vehicle has completely moved into
the lane. If this occurs, the system may warn driver by blinking the
system indicator and sounding the chime. The driver may have to
manually control the proper distance away from vehicle traveling
ahead.
- When driving on some roads, such as winding, hilly, curved, nar-
row roads, or roads which are under construction, the sensor may
detect vehicles in a different lane, or may temporarily not detect a
vehicle traveling ahead. This may cause the system to work inap-
propriately. The detection of vehicles may also be affected by vehi-
cle operation (steering maneuver or traveling position in the lane,
etc.) or vehicle condition. If this occurs, the system may warn
driver by blinking the system indicator and sounding the chime
unexpectedly. The driver will have to manually control the proper
distance away from the vehicle traveling ahead.
• The approach warning chime may sound and the system display
may blink when the sensor detects some reflectors which are fitted
on vehicles in other lanes or on the side of the road. This may
cause the DCA system to operate inappropriately. The sensor may
detect these reflectors when the vehicle is driven on winding
roads, hilly roads or when entering or exiting a curve. The sensor
may also detect reflectors on narrow roads or in road construction
zones. In these cases driver will have to manually control the
proper distance ahead of own vehicle. Also, the sensor sensitivity
can be affected by vehicle operation (steering maneuver or driving
position in the lane) or traffic or vehicle condition (for example, if a
vehicle is being driven with some damage).
• The DCA system automatically decelerates own vehicle to help
assist the driver to maintain a following distance from the vehicle
ahead. Manually brake when deceleration is required to maintain a safe distance upon sudden braking by
the vehicle ahead or when a vehicle suddenly appears in front of own vehicle. Always stay alert when using
the DCA system.
• When the vehicle ahead detection indicator lamp is not illuminated, system will not control or warn the driver.
• Never place a foot under the brake pedal. A foot may be caught when the system controls the brake.
• Depending on the position of the accelerator pedal, the system may not be able to assist the driver to
release the accelerator pedal appropriately.
• If the vehicle ahead comes to a standstill, the vehicle decelerates to a standstill within the limitations of the
system. The system will release brake control with a warning chime once it judges the vehicle is at a stand-
still. To prevent the vehicle from moving, the driver must depress the brake pedal. [The system will resume
control automatically once the system reaches 5 km/h (3 MPH)].
