Parking assist
Rear parking assist9 Warning
It is the driver who bears full
responsibility for the parking
manoeuvre.
Always check the surrounding
area while reversing and using the rear parking assist system.
The rear parking assist makes
parking easier by measuring the
distance between the vehicle and
rear obstacles. It informs and warns
the driver by giving acoustic and
visual signals.
The system has four ultrasonic
parking sensors in the rear bumper.
Activation
When reverse gear is engaged, the
system is ready to operate
automatically.
An illuminated LED in the parking
assist button r indicates that the
system is ready to operate.
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
The instructions in the display show:
● general hints and warning messages
● a hint when driving faster than 18 mph during parking slot
searching mode, or 5 mph in
guiding mode
● the demand to stop the vehicle, when a parking slot is detected
● the direction of driving during the
parking manoeuvre
● the demand to gearshift rearwards or forwards
● the demand to accelerate or brake
● for some of the instructions a progress bar is shown in the
Driver Information Centre
● the successful parking indicated by a pop-up symbol and a chime,
● the cancelling of a parking manoeuvreDisplay priorities
Advanced parking assist indication on the Driver Information Centre can beinhibited by vehicle messages with a
higher priority. After approving the
message by pressing SET/CLR on
the turn signal lever, advanced
parking assist instructions appear
again and the parking manoeuvre can
be continued.
Deactivation
The system is deactivated by:
● a long press of D
● parking manoeuvre successfully ended
● driving faster than 18 mph during
parking slot search
● driving faster than 5 mph during parking guidance
● driver interference on steering wheel detected
● exceeding number of maximum gear changes: eight parking
cycles when parallel parking or
five cycles when perpendicular
parking
● switching off the ignitionDeactivation by the driver or by the system during manoeuvring will beindicated by Parking Deactivated on
the display. Additionally an acoustic
signal sounds.
Fault
A message appears when:
● there is a fault in the system; control indicator r illuminates
in the instrument cluster
● the driver did not successfully complete the parking manoeuvre
● the system is not operational
● any of the deactivation reasons described above apply
If an object is detected during parking instructions, Stop is indicated on the
display. Removing the object will resume the parking manoeuvre. If the
object is not removed, the system will
be deactivated. A long press of D
will activate the system and search for
a new parking slot.
