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
■ heated mirrors
■ heated seats
■ fanIn 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 operating141
Release the accelerator pedal and
the speed limiter function is
reactivated once a speed lower than the limit speed is obtained.
Deactivation
Press button y: speed limiter is
deactivated and the vehicle can be
driven without speed limit.
The limited speed is stored.
Additionally, a corresponding
message appears on the Uplevel-
Display.
Resume limit speed Turn thumb wheel to RES/+. The
stored speed limit will be obtained.
Switching off Press button L, the speed limit
indication in the Driver Information
Centre extinguishes. The stored
speed is deleted.
By pressing button m to activate
cruise control or by switching off the
ignition, speed limiter is also
deactivated and the stored speed is
deleted.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.
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. The interval between the
Page 146 of 233

144Driving and operating
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.

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.
