●
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.
Pressing buttons ④ and ⑤ on the
steering wheel adjusts vehicle distance
to any of the four available levels. At
each level, vehicle distance is in direct
proportion to vehicle speed. The faster
the speed, the longer the 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. At the target cruise speed,
if you accelerate without performing
any other operations, the vehicle
accelerates and then returns to target
cruise speed after the accelerator
pedal is released.
●
When you press the brake pedal
with ACC activated to slow down the
vehicle, ACC goes into standby mode.
After the brake is released, ACC needs
to be reactivated.
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 vehicle stops for 30 seconds to
three minutes, press the accelerator
pedal or pushing up lever② to
reactivate ACC.
System Limitations
●
The front mmWave radars are installed
in the front of the vehicle. Blockage
of its detection area by contaminants
can disturb the intended function. In
particular, if the sensor is covered by
snow completely, the ACC system exits.
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.
●
Traffic flow and weather conditions,
such as rain and fog, must be heeded
for setting vehicle distance on the
ACC system. After the ACC system is
properly set, the driver must be able
to decelerate until the vehicle stops at
any time.
●
The ACC system may not be
able to identify stationary or slow-
moving objects, such as vehicles,
the end of traffic, toll booths,
bicycles, motorcycles, or pedestrians.
This means a risk of collision and
requires the driver to beware of the
surroundings.
●
The ACC system cannot identify
pedestrians or oncoming vehicles.
●
The ACC system can only achieve
limited braking instead of emergency
braking.
