●
ACC cannot be activated in special
driving modes like tow/snow/mud/
sand/terrain.
Precautions
●
ACC is a comfort system rather than
a safety system, obstacle detector or
collision warning system. The driver
must keep control of vehicle at all
times and be fully responsible for the
vehicle.
●
ACC assists instead of replacing the
role of the driver. The driver is
responsible for abiding by tra󽗋c rules
and keeping vehicle control.
●
For safety reasons, ACC cannot be
activated with ESC disabled.
●
The ACC is suitable for use on highways
and roads in good conditions, rather
than on complex urban or meandering
roads.
●
It is the driver's responsibility to keep
distance from the vehicle ahead. The
ACC system's vehicle distance meets
the minimum distance required in
driving environments in the country.
●
Vehicle control is transferred to the
driver if the accelerator or brake pedal
is pressed with ACC active. As a result,
the ACC system cannot keep a safe
distance from the vehicle ahead.
●
ACC may have no or slow responses to
a vehicle ahead that brakes or stops
suddenly, resulting in a risk of late
braking. In such cases, there will be no
take-over request.
●
In some cases, such as when the
vehicle ahead is going too slow, when
lane change is too fast, or when the
safe distance from the vehicle ahead
is too short, there is no adequate
time for the system to decrease the
relative speed. In this case, the driver
must response. The system cannot give
audio or visual warnings in every case.
●
If ACC is activated with the vehicle
stationary, the system identi󽗉es any
stationary obstacle ahead and keeps
the vehicle still to ensure a safe
startup and prevent collision. However,
this function cannot identify all the
obstacles, so the driver must be alert
to the front obstacles or other tra󽗋c
participants.
●
A short distance from an adjacent lane
(or a vehicle on an adjacent lane that
is too close to the ACC vehicle's lane)
may trigger ACC to brake.
●
Vehicles coming into the ACC vehicle's
lane and within the detection range of
its front mmWave radars are identi󽗉ed
as target vehicles and prompt a
response accordingly, which may lead
to hard or late braking.
●
Detection may be a󽗈ected or delayed
in some environments. If the radar
re󽗊ection cross-sectional area of the
target (a bicycle, four-wheeler, or
pedestrian, for example) is too small,
the system may not be able to
establish its distance, resulting in
either late or no response to those
vehicles. In such cases, vehicle speed
must be controlled by the driver.
In addition, detection may also be
a󽗈ected or delayed by noise or
electromagnetic interference.
●
ACC cannot target vehicles with too
small contact ratio, so the driver must
keep control of the vehicle.
●
When the vehicle stops as it follows
a vehicle ahead, in rare cases, the
system does not recognize the end of
the vehicle ahead but the lower end of
the target (for example, the rear axle of
a truck with a high chassis or a vehicle
bumper). In such cases, the system
cannot ensure proper stop distance, so
