162Driving and operating
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 10 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
10 metres for parallel parking slots or
six metres for perpendicular parkingslots after 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 steered
into 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 parkingslots on the driver side, switch on turn
signal indicator on the driver side for
the duration of the search.
As soon as the turn signal indicator is switched off, the system searches for
parking slots on the passenger side again.Display indication
The instructions on 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 shift into reverse or
first gear.
■ The demand to accelerate or brake.
■ For some of the instructions a progress bar is shown in the DriverInformation Centre (DIC).

parallel parking or five cycles when
perpendicular parking
■ switching off the ignition
Deactivation 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.
■ 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.Basic notes on parking assist
systems9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.
Special attention must be paid to
low obstacles which can damage
the lower part of the bumper.
Caution
Performance of the system can be reduced when sensors are
covered, e.g. by ice or snow.
Performance of the parking assist
system can be reduced due to
heavy loading.
Special conditions apply if there
are taller vehicles in the vicinity
(e.g. off-road vehicles, mini vans,
vans). Object identification and
Driving and operating165
When the system detects a vehicle inthe side blind zone while driving
forward, either while passing a
vehicle or being passed, an amber
warning symbol B will illuminate in
the relevant exterior mirror. If the
driver then activates the turn signal,
the warning symbol B starts flashing
amber as a warning not to change
lanes.
Side blind spot alert is active from
speeds of 6 mph up to 87 mph.
Driving faster than 87 mph
deactivates the system, indicated by
low lighting warning symbols B in
both exterior mirrors. Reducing the
speed again will extinguish the
warning symbols. If a vehicle is then
detected in the blind zone, the
warning symbols B will illuminate as
normal on the relevant side.
When the vehicle is started, both exterior mirror displays will briefly
come on to indicate that the system is operating.
The system can be activated or
deactivated in the Info-Display,
