• When suddenly accelerating and
approaching the vehicle ahead at high
speed (an obvious speed difference with
the vehicle ahead), the driver should
brake in time.
• When driving on a steep downslope, it
may be difficult for this function to keep a
proper distance from the vehicle ahead.
Under such circumstances, be extra
careful and be ready to brake at any
time. Never use ACC when the vehicle is
under heavy load.
• ACC cannot recognize pedestrians, two-
wheeled vehicles (such as bicycle),
three-wheeled vehicles (such as
tricycles), vehicles loaded with irregularly
shaped goods or special-shaped
vehicles, animals, objects scattered on
the road, overturned vehicles, people
standing next to or behind the vehicle,
etc.
• ACC has a poor recognition rate for
stationary or slow-moving vehicles and
cannot recognize oncoming vehicles.
When using the ACC function, driver
needs to always pay attention to the road
conditions and vehicle status, and ready
to control the vehicle in time.
• When ACC works, if the driver press the
accelerator pedal, the vehicle control will
be taken over by the driver, and respond
to the driver’s acceleration desire. The
control function of ACC will not work.
• When entering or exiting a curve, the
target selection may be delayed or
disturbed. ACC may have unexpected
braking or late braking.
• In some cases (the speed of preceding
vehicle is too low relative to your own
vehicle, and the preceding vehicle jumps
into the lane closely, etc.), ACC system
does not have enough time to reduce the
relative speed. In this case, the driver
must respond appropriately.
• If the preceding vehicle suddenly brakes,
ACC may fail to respond timely or react
too slowly. In this case, the driver will not
receive the takeover request. The driver
should press the brake pedal for
emergency braking.
• At a sharp turn, e. g. a serpentine road,
ACC cannot detect the preceding vehicle
normally due to the visual field limit of
front camera, which may lead to the
acceleration of ACC vehicle. The driver is
required to respond appropriately based
on actual conditions.
• If the distance between the ACC vehicle
and the adjacent lane is too small (or the
vehicle on the adjacent lane is too close
to the lane of ACC vehicle), ACC system
may react to that vehicle and brake.
In following situations, the driver must
be more alert:
• When ACC is activated and confirmed to
start with the vehicle is stationary, if there
are pedestrians, children, animals, two-
wheeled vehicles (such as bicycle),
three-wheeled vehicles (such as
tricycles) or obstacles ahead, the ACC
cannot detect and identify them, and
there is a serious collision risk. The driver
must confirm the area ahead of vehicle is
safe before activating ACC to control the
vehicle when starting to drive.
