[Driving on a slope
OADAS012R

Forward Collision-Avoidance Assist
may not detect other vehicles,
pedestrians or cyclists in front of
you whilst driving uphill or downhill
adversely affecting the performance
of the sensors.
This may result in unnecessary
warning or braking assist, or no
warning or braking assist when
necessary.
Also, vehicle speed may rapidly
decrease when a vehicle, pedestrian
or cyclist ahead is suddenly detected.
Always have your eyes on the road
whilst driving uphill or downhill and
if necessary, steer your vehicle and
depress the brake pedal to reduce
your driving speed in order to
maintain a safe distance.
[Changing lanes
OADAS030R
[A] : Your vehicle,
[B] : Lane changing vehicle
When a vehicle moves into your
lane from an adjacent lane, it cannot
be detected by the sensor until it
is in the sensor's detection range.
Forward Collision-Avoidance Assist
may not immediately detect the
vehicle when the vehicle changes
lanes abruptly. In this case, you must
maintain a safe braking distance,
and if necessary, steer your vehicle
and depress the brake pedal to
reduce your driving speed in order to
maintain a safe distance.
