Warning
● The ACC system does not respond to
pedestrians.
● The ACC system does not respond to
stationary or slowly moving vehicles
or objects, and does not respond to
oncoming vehicles.
● The ACC system can assist the
driver, but it cannot replace the
driver. Even though the ACC system
is activated, the driver still needs to
drive carefully and observe the rules
on speed limit.
● When the ACC system is in
operation, if the driver depresses
the accelerator pedal, the vehicle
will be taken over by the driver, and
the system will temporarily be in a
waiting state. If the accelerator pedal
is released in a short period of time,
the system will continue to operate.
If the acceleration time is too long,
the ACC system will exit, and needs
to be reset or reactivated for use.
● When the vehicle goes into or out of
a curve, the selection of the target
Warning Warning
vehicle ahead may be delayed or
disrupted, in which case the vehicle
may not brake as expected or brake
too late.
● In some cases (such as sudden
deceleration of the vehicle ahead, too
fast lane change or too small safety
distance), the ACC system does not
have enough time to reduce relative
speed. In this case, the driver must
respond appropriately.
● If a vehicle ahead brakes suddenly
(emergency stop), the ACC system
may fail to respond or be slow in
responding to the vehicle ahead,
resulting in the risk of late braking.
In this case, the driver will not
receive a takeover request and needs
to respond in advance.
● On sharp curves, the vehicle ahead
may be lost in the front millimeter-
wave radar eld of view for a short
period of time, causing the vehicle to
accelerate.
● If the vehicle runs too close to an
adjacent lane or another vehicle on
an adjacent lane runs too close to
the vehicle, the ACC system may
apply braking in response to the
corresponding vehicle.
● If a vehicle suddenly moves to the
lane of the vehicle with the ACC
system activated and is within the
radar's detection range, it will be
recognized as the target vehicle,
which may lead to strong or late
braking.
● In some environments, detection may
be aected or delayed, such as when
the radar cross-sectional area of the
target is too small (such as bicycles,
pedestrians, electric bicycles,
etc.), the system may not be able
to conrm the risk of the distance
from the preceding vehicle, which
will lead to delayed or unresponsive
response to such vehicles. In this
case, the driver needs to control
the vehicle speed. Moreover,
radar detection may be aected
