In the following instances, the engine will restart
when the ACC is active:
• If the accelerator is depressed.
• When the ACC has resumed speed and dis

• If the vehicle ahead has moved on.
The brake servo and the electromechanical
steering will not function if the engine is
switched off.
• Never allow the vehicle to roll if the engine
is switched off.

r::l The Park Assist system has system-related
l!J limitations . For example, the Park Assist sys
t e m cannot help you to park the
vehicle on tight
b e nd s.
r::l Wh en parking parallel to the road , a warning
L!J signal can be heard to tell the driver to switch
between driving forwards and reversing because
the change
of direct ion should not take place in the
permanent tone area
of the ParkPilot.
r::l The progress bar in the instrument cluster
l!J display will symbolically indicate the relative
distance remaining .
W If the Park Assist system turns the steering
l!J wheel when the vehicle is stationary , the 6l
symbol appears as well. Depress the brake pedal
so that the steering movement takes place with the
vehicle stationary, keeping the required number of
parking movements to a minimum.
r::l If the parking result worsens after a wheel is
~ changed, the system will first have to syn
chronise
itself with the new wheel. The synchroni
sation procedure is carried out
automatically while
the vehicle is in motion. You can support this proc
ess by driving slowly (less than 20 km/h (12 mph))
through a bend, e.g. in an empty car park.
