Information
Depending on the traffic situation, e.g. slow moving
traffic, stopping is initiated by a slow creeping
phase, which brings the vehicle to a standstill.
Information
When adaptive cruise control is operating normally
or when the HOLD function is active, the brake pedal
may feel different and you may hear hydraulic
noises. This behaviour is normal for the system.
There is no fault.

ped and speed and distance control will be resumed,

moving traffic.
