Vehicle battery state of charge
function
The function guarantees longest
vehicle battery life via a generator with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, following
systems are reduced automatically in two stages and finally switched off:
■ Auxiliary heater
■ Heated rear window and mirrors■ Heated seats
■ Fan
In the second stage a message which
confirms the activation of the vehicle
battery discharge protection will be
displayed in the Driver Information
Centre.
Switching off electric lights To prevent discharge of the vehicle
battery when the ignition is switched
off, some interior lights are switched
off automatically after some time.

Driving and operating135
In the Colour-Info-Display, distance isdisplayed by coloured zones in front
of or behind the vehicle.
The distance indication in 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, distance
indication appears again.
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 84 and a
message pops-up in the Driver
Information Centre.
Vehicle messages 3 92.Advanced parking assist9 Warning
It is the driver who bears full
responsibility for accepting the
parking slot suggested by the
system and the parking
manoeuvre.
Always check the sourrounding
area in all directions when using
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 by the Driver
Information Centre or the Colour-Info-
Display 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.
Long press of button D (approx. one
second) activates or deactivates the
advanced parking assist, see
separate description below.
Page 140 of 217

138Driving and operating
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.
Pay always attention on the sound of
the front-rear parking assist.
Continuous sound means 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.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 shift 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.Selecting of parallel or perpendicular
parking
When searching for a parking slot,
select parallel or perpendicular
parking slot by pressing SET/CLR
button on the turn signal lever.

Driving and operating139
If the system is equipped with Colour-
Info-Display, select the type of
parking slot by tapping the display
icon 6 or 7.
The display shows the type of parking
slot.
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
indicator to the driver side for the
durance of the search.
As soon as the turn indicator is
switched off, the system searches for
parking slots on the passenger side
again.
Display priorities
After activating the advanced parking assist, a message appears in the
Driver Information Centre or Colour-
Info-Display. Advanced parking
assist indication in 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:
■ 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,

Driving and operating141correct distance indication in the
upper part of these vehicles
cannot be guaranteed.
Objects with a very small reflection
cross-section, e.g. objects of
narrow size or soft materials, may
not be detected by the system.
Parking assist systems do not
detect objects outside the
detection range.
Notice
It is possible that the sensor detects a non-existing object caused by
echo disturbance from external
acoustic noise or mechanical
misalignments (sporadic false
warnings might happen).
Make sure that the front license plate
is properly mounted (not bent and no
gaps to the bumper on the left or
right side) and the sensors are well
in place.
Advanced parking assist system
may not respond to changes in the
available parking space after
initiating a parking manoeuvre. The
system may recognize an entry, a
gateway, a courtyard or even a crossing as parking slot. After
selecting reverse gear the system
would start a parking manoeuvre.
Take care of the availability of the
suggested parking slot.
Surface irregularities, e.g. on
construction zones, are not detected by the system. The driver accepts
responsibility.
Notice
If engaging a forward gear and
exceeding a certain speed, the rear
parking assist will be deactivated
when the rear carrier system is
extended.
If engaging reverse at first, the
parking assist will detect the rear
carrier system and provide a buzzing
sound. Press r or D briefly to
deactivate the parking assist.
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.
