Emergency Stop Signal
The emergency stop signal is not a system
u
that can prevent a possible rear-end
collision caused by your hard braking. It is
always recommended to avoid hard braking
unless it is absolutely necessary.
If the ABS stops working for a certain period
u
during braking, the emergency stop signal
may not activate at all.
