Function Limitations
The Adaptive Cruise Control (ACC) camera
sensor has a limited detection range. In the
following situations (including but not limited to),
the sensor may fail to detect the vehicle ahead or
misdetect, leading to delayed system response
or unintended braking due to collision risk:
● When approaching or driving through a curve,
the ACC system may misidentify vehicles in
other lanes or fail to recognize vehicles in the
same lane.
● If the vehicle ahead is positioned diagonally
in front and potentially outside the detection
range, the ACC system may not recognize it.
● If a vehicle moves into the same lane in front,
posing a collision risk, the ACC system may
unexpectedly brake.
● If the vehicle ahead is turning and there is
a stationary vehicle further ahead, there is
a collision risk and the ACC system may
unexpectedly brake.
● While driving on sloped roads, the ACC
system may fail to detect vehicles ahead.
In addition to the above situations, drivers
using the ACC system should be vigilant and
ready to take over control when encountering the
following conditions, and turn off the ACC system
if necessary:
● Rapidly approaching the vehicle ahead or if
the vehicle ahead suddenly brakes, and the
ACC system cannot apply sufficient braking
force.
● Encountering trucks or trailers with higher
chassis.
● The camera sensor's performance may be
affected while driving in tunnels, possibly
failing to detect distant vehicles or having
unstable detection.
● Adverse weather conditions like heavy fog,
rain, snow, or sandstorms can affect sensor
detection performance.
● Low road friction coefficient, where rapid
changes in tire tractioncan cause the vehicle
to slip.
● Insufficient or excessive ambient lighting
around the vehicle can affect sensor detection
performance.
● The presence of objects like rails or metal
plates on the road ahead can interfere with
sensor detection.
● Vehicle collisions, severe vibrations, or other
incidents that might change the sensor's
position.
● If the vehicle ahead has items protruding from
its sides or rear end, the ACC system may
not recognize these items.
Indicator Lights
When ACC is activated, the indicator
light illuminates in green.If not activated, it
remains off.
If ACC malfunctions, the indicator light
illuminates in red, indicating the need to check if
the camera is obstructed.
In emergency situations ahead, the system
will prompt "Please Take Over" or "Please Take
Over Immediately," accompanied by a buzzer
alarm.
If the driver presses the accelerator pedal
during ACC activation, the vehicle enters override
mode (driver takeover), and the set cruise speed
will ash.
