146Driving and operatingAdvanced parking assist9Warning
The driver bears full responsibility
for accepting the parking slot
suggested by the system and the
parking manoeuvre.
Always check the surrounding
area in all directions when using
the advanced parking assist.
The advanced parking assist
measures a suitable parking slot
while passing, calculates the
trajectory and automatically steers
the vehicle into a parallel or
perpendicular parking slot.
Instructions are given in the Driver
Information Centre 3 87 or,
depending on the version, on the
Colour-Info-Display 3 92, supported
by acoustic signals.
The driver must control acceleration,
braking and gear shifting, while
steering is done automatically.
Advanced parking assist can only be
activated when driving forwards.Advanced parking assist is always
combined with front-rear parking assist, see previous section. Both
systems use the same sensors in the front and rear bumper.
Button D and operation logic
Advanced parking assist and front-
rear parking assist both use the same
button for activation and deactivation:
A brief press of D activates or
deactivates the parking assist.
A long press of D (approx.
one second) activates or deactivates
the advanced parking assist, see
separate description below.
Button logic operates the systems by
pressing as follows:
● If only front-rear parking assist is active, a brief press deactivates
front-rear parking assist.
● If only front-rear parking assist is active, a long press activates
advanced parking assist.
● If only advanced parking assist is
active, a brief press activates
front-rear parking assist.
● If only advanced parking assist is
active, a long press deactivates
advanced parking assist.
● If forward gear or neutral is selected, a brief press activates
or deactivates only front parking
assist.
● If reverse gear is selected, a brief
press activates or deactivates
front and rear parking assist.
148Driving and operatingWhen a slot is detected, a visual
feedback in the Driver Information
Centre and an acoustic signal is
given.
Select parallel or perpendicular
parking slot by tapping the icon 6 or
7 on the Colour-Info-Display.
When a slot is detected, a visual
feedback on the Colour-Info-Display
and an acoustic signal is given.
If the driver does not stop the vehicle
within ten metres for parallel parking
slots or six metres for perpendicular parking slots after a parking slot is
proposed, the system starts to search
for another suitable parking slot.
Park guiding mode
The parking slot suggestion of the
system is accepted when the vehicle
is stopped by the driver within ten
metres for parallel parking slots or six metres for perpendicular parking slotsafter the Stop message is given. The
system calculates the optimal path
into the parking slot.
A brief vibration in the steering wheel
after engaging reverse gear indicates
that the steering is controlled by the system. Then the vehicle is steeredinto the slot automatically by giving
the driver detailed instructions for
braking, accelerating and gear
shifting. The driver must keep hands
away from the steering wheel.
Always pay attention to the sound of
the front-rear parking assist.
Continuous sound indicates that the
distance to an obstacle is less than
approx. 30 cm.
If, for any reason, the driver must take over control of the steering, hold the
steering wheel only at the outer edge. Automatic steering is cancelled in thisevent.Changing the parking side
The system is configured to detect parking slots by default on the
passenger side. To detect parking
slots on the driver side, switch on turn
signal indicator to the driver side for
the durance of the search.
Driving and operating149As soon as the turn signal indicator is
switched off, the system searches for
parking slots on the passenger side
again.Display indication
