Note
●
The HHC function is only available when
the vehicle is in the D or R gear, on the
ramp, and the brake pedal is going to
be released, it'll automatically generate
braking force to keep the car stationary.
●
The HHC function lasts for about 1 s. The
held braking may be released in advance
depending on factors such as the driver
operation and the ramp.
Caution
HHC can provide brake assistance, but it cannot
go beyond the laws of kinematics. For safety
reasons, the driver shall timely press the brake
pedal based on the actual situation to avoid
accidents caused by the sliding downhill too
fast.
