●
The driver must select a safe vehicle
distance.
●
The system adjusts vehicle speed to
keep a suitable distance from the
vehicle ahead on the same lane. The
following distance (four levels), in
direct proportion to the vehicle speed,
is adjustable by buttons ③ and ④
on the steering wheel. The higher
the vehicle speed, the greater the
following distance.
Increasing/Decreasing speed with ACC
active
●
When ACC is activated, you can press
the accelerator pedal to reach the
set target cruise speed in advance.
The system then enters over speed
mode. When the vehicle is already
traveling at the target cruise speed and
the accelerator pedal is pressed and
does not perform other operations,
the vehicle returns to the target speed
set before acceleration; if the brake
pedal is pressed, ACC automatically
enters standby status, and needs to
be re-activated after the brake pedal is
released.
Follow-to-stop/start
●
Controlled by ACC, the vehicle can
stop when the vehicle ahead stops in
normal driving conditions and resume
driving automatically following the
vehicle ahead if the stop is less than
30 seconds.
●
If the stop time is between 30 seconds
and 3 minutes, the driver needs to
either press the accelerator pedal or
pull up the lever ② to activate ACC.
●
If the vehicle stops for more than three
minutes, the ACC system will enter
standby mode, with EPB engaged.
System Limitations
●
The front mmWave radar and multi-
purpose camera are positioned in
the front area of the vehicle. If their
󽗉elds of view are obstructed, certain
functions may not operate as intended
due to interference. If any of these
sensors is blocked or covered, ACC
directly deactivates and informs of
this on the instrument cluster. System
function will recover after blockage is
removed and the vehicle is restarted or
runs on normal roads for a while.
●
Front mmWave radar sensors may
have a transient function failure from
limited detection if the vehicle runs
under special conditions, such as
circular ramps or tunnels, for an
extended period. The function can be
recovered by restarting the vehicle or
driving on normal roads for a while.
●
Reaching or leaving a curve may delay
or disturb target selection. In such
cases, the ACC vehicle may not brake
as expected or may brake late.
●
On roads with sharp curves, such as
winding roads, the vehicle ahead may
be out of ACC sensor detection for
several seconds due to sensor vision
limitations, possibly causing the ACC
vehicle to accelerate automatically.
●
Tra󽗋c 󽗊ow and weather conditions,
such as rain and fog, must be heeded
for setting vehicle distance on the
ACC system. After ACC is properly
set, the driver should make sure that
the vehicle can be decelerated to a
complete stop at any time.
●
The ACC system may not be able
to identify stationary or slow-moving
objects, such as vehicles, the end
of tra󽗋c, toll booths, bicycles, or
pedestrians. This means a risk of
collision and requires the driver to
beware of the surroundings.
