●
The AEB system cannot work normally
when the ESC function is disabled or
the fault light is on.
●
If PCW gives an alarm, the driver must
brake based on tra󽗋c conditions to
decrease vehicle speed or steer away
from obstacles.
●
If the vehicle travels too close to
the vehicle ahead for too long, a
safety distance warning will be given.
If the vehicle ahead brakes suddenly,
collision may be unavoidable.
●
The system will not trigger AEB when
the driver is aware of an emergency
warning, but turns the steering wheel,
presses the throttle pedal hard or
brakes hard.
●
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.
●
Sometimes the front mmWave radar or
multifunctional video controller detect
dirt or foreign matter on its surface,
then PCW and AEB would malfunction,
you need to clean the dirt or foreign
matter immediately.
●
As the pedestrian protection function
is limited by certain physical
conditions, the driver must take timely
and e󽗈ective control of the vehicle
under dangerous conditions.
●
The system cannot completely protect
pedestrians or avoid accidents and
severe injuries on its own.
●
Under certain complex conditions,
such as on winding roads, the
pedestrian protection function may
trigger unnecessary warning or
braking. For example, on the curving
main lane.
●
In case of system failure, such as
radar or camera misalignment, the
pedestrian protection function may
trigger wrong warnings or braking.
For example, the front millimeter
wave radar and multi-functional video
controller angle are out of alignment.
●
The brake pedal becomes harder if
AEB is triggered. A large amount of
hydraulic pressure will be required to
push the caliper in a short time and
there will be a sizzling noise.
●
The AEB system activates only after all
doors are closed and all occupants are
buckled up. Note: The AEB system will
fail to work if:
●
Any door is not closed or it is opened
when the vehicle is moving.
●
A seat belt is not fastened or it
is unfastened when the vehicle is
moving.
●
The driver accelerates or decelerates
rapidly or turns the steering wheel
quickly.
●
The vehicle travels on a curve with a
small turning radius.
●
System performance may be a󽗈ected
in the following cases:
●
Strong front bumper impact from
accidents or other causes.
●
Improperly in󽗊ated or worn out tires.
●
Unquali󽗉ed tires installed.
●
Snow chains installed.
●
Use of a small spare tire or tire repair
kit.
●
Make sure to go to a BYD
authorized dealer or service provider
for professional calibration of the
medium-range front mmWave radar
and multifunctional video controller in
any of the following situations:
