Battery discharge protection
Vehicle battery state of charge
function
The function guarantees longestvehicle battery life via a generator
with controllable power output and
optimised power distribution.
To prevent discharge of the vehicle
battery when driving, the following
systems are reduced automatically in two stages and finally switched off:
● auxiliary heater
● heated rear window
● heated windscreen
● heated 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.
Driving and operating161The complete attention of the
driver is always required while
driving. The driver must always be
ready to take action and apply the
brakes.
System limitations
The system is designed to warn of vehicles only, but may react also to
other objects.
In the following cases, forward
collision alert may not detect a vehicle ahead or sensor performance is
limited:
● on winding roads
● when weather limits visibility, e.g.
fog, rain, or snow
● when the sensor is blocked by snow, ice, slush, mud, dirt, or
windscreen damage
Following distance
indication
The following distance indication
displays the distance to a preceding
moving vehicle. The front camera in
the windscreen is used to detect the
distance of a vehicle directly ahead in
the vehicle's path. It is active at
speeds above 25 mph.
When a preceding vehicle is detected
ahead, the distance is indicated in
seconds, displayed on a page in the
Driver Information Centre 3 96 . Press
MENU on the turn signal lever to
select Vehicle Information
Menu ? and turn the adjuster
wheel to choose following distance
indication page.
The minimum indicated distance is
0.5 seconds.
If there is no vehicle ahead or the vehicle ahead is out of range, two
dashes will be displayed: -.- sec.
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 signals
and display indication.
162Driving and operating
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
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 rear obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 96 or,
depending on the version, on the Colour-Info-Display 3 101.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After approving the
message by pressing SET/CLR on
the turn signal lever, distance
indication appears again.Deactivation
The system automatically switches
off when reverse gear is disengaged.
Manual deactivation is also possible
by pressing the parking assist button
r .
In both cases, the LED in the button
extinguishes.
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
three seconds then extinguishes.
164Driving and operatingWhen the system is deactivated, the
LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
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 rear and
front obstacles is displayed by
changing distance lines in the Driver
Information Centre 3 96 or,
depending on the version, on the Colour-Info-Display 3 101.
The distance to rear and front
obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 96.
The distance indication can be
inhibited by vehicle messages with a
higher priority. After approving the
message by pressing SET/CLR 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 3 101.
Deactivation
The system is deactivated
automatically when vehicle speed
exceeds 16 mph.
Manual deactivation is also possible by pressing the parking assist button
r .
When the system is deactivated, the LED in the button extinguishes and
Park Assist Off pops-up in the Driver
Information Centre.
Driving and operating167
The distance to rear and front
obstacles is displayed by changing
distance lines in the Driver
Information Centre 3 96.
The distance indication can be
inhibited by vehicle messages with a higher priority. After approving the

Activation of advanced parking assist Advanced parking assist can only be
activated when driving forwards.When searching for a parking slot, the
system is ready to operate with a long
press of D.
The system recognises and memorises ten metres for parallel
parking slots or six metres for
perpendicular parking slots in the
parking assist mode.
The system can only be activated at
a speed up to 18 mph and the system searches for a parking slot at a speed up to 18 mph.
The maximum allowed parallel
distance between the vehicle and a
row of parked cars is 1.8 metres for
parallel parking and 2.5 metres for
perpendicular parking.
Driving and operating169When 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 slots
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
slots 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
Driver Information Centre.
● The successful completion of the
parking manoeuvre indicated by
a pop-up symbol and a chime.
● The cancelling of a parking manoeuvre.
