Indication
The system warns the driver with
acoustic signals against potentially
hazardous obstacles behind the
vehicle in a distance range up to
1.5 metres and in front up to
1.2 metres . Depending on which side
of the vehicle is closer to an obstacle,
you will hear acoustic warning signals in the vehicle on the respective side.
The interval between the sounds
becomes shorter as the vehicle gets
closer to that obstacle. When the
distance is less than approx. 30 cm,
the sound is continuous.
Additionally the distance to obstacles
is shown in the Driver Information Centre 3 90 or, depending on the
version, on the Colour-Info-Display 3 95.
The distance to a front and rear
obstacle is displayed by changing
distance lines in the Driver
Information Centre.
The distance indication can be
inhibited by vehicle messages with a higher priority. After approving the
message by pressing the SET/CLR
button on the turn signal lever,
distance indication appears again.The distance to obstacles is shown on
the Colour-Info-Display by coloured
zones in front of or behind the vehicle 3 95.
Fault
In the event of a fault or if the system
does not work temporarily, e.g. because of high external noise level
or other interference factors, the LED in the button flashes for 3 seconds
and then extinguishes. Control
indicator r illuminates in the
instrument cluster 3 88 and a
message pops-up in the Driver
Information Centre.

Advanced parking assist9 Warning
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 90 or,
depending on the version, on the
Colour-Info-Display 3 95, 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 button D activates
or deactivates the parking assist.
A long press of button 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.
Driving and operating147
When 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 10 metres for parallel parking
slots or 6 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
6 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 parking
148Driving and operating
slots on the driver side, switch on turn
signal indicator to the driver side for
the durance 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 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 DriverInformation Centre,■ the successful parking indicated by
a pop-up symbol and a chime,
■ the cancelling of a parking manoeuvre.
Display priorities
Advanced parking assist indication on
the Driver Information Centre can be
inhibited by vehicle messages with a higher priority. After approving the
message by pressing the SET/CLR
button 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 button 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: 8 parking cycles
when parallel parking or 5 cycles
when perpendicular parking,
■ switching off the ignition.
Deactivation by the driver or by the
system during manoeuvring will be
indicated 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
150Driving and operating
Notice
After production, the system
requires a calibration. For optimal parking guidance, a driving distance of at least 6 miles, including a
number of bends, is required.
Side blind spot alert The Side blind spot alert system
detects and reports objects on either
side of the vehicle, within a specified
"blind spot" zone. The system alerts
visually in each exterior mirror, when
detecting objects that may not be
visible in the interior and exterior
mirrors.
Side blind spot alert uses some of the advanced parking assist sensors
which are located in the front and rear
bumper on both sides of the vehicle.9 Warning
Side blind spot alert does not
replace driver vision.
The system does not detect:
■ Vehicles outside the side blind zones which may be rapidly
approaching.
■ Pedestrians, cyclists or animals.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects a vehicle in the 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.
Driving and operating151
The system can be activated or
deactivated in the Info-Display,
vehicle personalisation 3 100.
Deactivation is indicated by a
message in the Driver Information
Centre.
Detection zones
The detection zones start at the rear
bumper and extend approx.
3 metres rearwards and to the sides.
The height of the zone is approx.
between 0.5 metres and 2 metres off
the ground.
Side blind spot alert is designed to ignore stationary objects, e.g.
guardrails, posts, curbs, walls and
beams. Parked vehicles or oncoming vehicles are not detected.
Fault Occasional missed alerts can occur
under normal circumstances and will
increase in wet conditions.
Side blind spot alert does not operate when the left or right corners of the
rear bumper are covered with mud,dirt, snow, ice, slush, or in heavy
rainstorms. Cleaning instructions
