Driving and operating167●detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.
Fault
In case the system requires a service,
a message is displayed in the Driver
Information Centre.
Additionally, warning lights l and
j illuminate at the same time.
When the system detects that its
function is not available, warning light l or j illuminates and stays on.
Additionally, a message in the Driver
Information Centre appears. The
system may be temporarily disrupted(for example: radar or camera
obscured by dirt, mud, snow etc.). In
this case, park the vehicle and switch
off the engine. Clean the windscreen
area around the camera and the
detection zone of the radar in the front bumper. When the warning lights and
messages still appear after starting
the vehicle again, seek the
assistance of a workshop.
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 parking assist measures the
distance between the vehicle and
obstacles behind the vehicle. It
informs and warns the driver by giving acoustic signals.
The system consists of four ultrasonic parking sensors in the rear bumper.
Notice
Attached parts in the detection area
cause system malfunction.
Activation
When reverse gear is engaged, the
system switches itself on
automatically. Readiness for
operation is indicated by a brief
acoustic signal.
The interval between the acoustic
signals becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm, the signal is continuous.

170Driving and operatingInfo Display
In vehicles with navigation system,
the rear view camera display is shown
on the Info Display.
Trajectory lane display image (1)
Depending on version, the trajectory
lane (1) of the vehicle is shown in blue
on the Info Display. It shows the path of the vehicle in accordance with the
steering angle.
Fixed lane display image (2)
The fixed lane display (2) shows the
path of the vehicle if the wheels are
kept straight.
Guide lines (3, 4, 5) are used together
with the fixed lane display (2) and
indicate the distance behind the
vehicle.The guide line intervals are as
follows:3 (red):30 cm4 (yellow):70 cm5 (green):150 cmSettings
Settings, e.g. brightness, can be set
via the Infotainment system. Refer to
Infotainment manual for further
information.
Deactivation
The camera is deactivated after a
delay if reverse gear is not engaged.
Fault
The rear view camera may not
operate properly when:
● the surrounding is dark
● the sun or the beam of headlights
is shining directly into the camera lens
● ice, snow, mud, or anything else covers the camera lens. Clean
the lens, rinse it with water, and
wipe it with a soft cloth

Driving and operating171● the rear doors are not closedcorrectly
● the vehicle had a rear-end accident
● there are extreme temperature changes
Lane departure warning The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. The system detects
lane changes and warns the driver in
the event of an unintended lane
change via visual and acoustic
signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn lights
● no active steering
If the driver is performing these
actions, no warning will be issued.Activation
The lane departure warning system is activated by pressing ì in the roof
console. The LED in the button
extinguishes to indicate that the
system is switched on.
When control indicator ì 3 101
illuminates in the instrument cluster,
the system is ready to operate. A
corresponding message also
appears in the Driver Information
Centre 3 104.
Control indicator ì extinguishes
when the system is not ready to warn the driver.
The system is only operable at
vehicle speeds above approx.
37 mph and if lane markings are
available and detected.
If the turn lights are not operated
when changing lanes, i.e. an
unintended lane change is detected,

176Driving and operatingIn the case of trailer loads of
1200 kg or more, the vertical coupling load should not be less than 50 kg.
Rear axle load When the trailer is coupled and the
towing vehicle fully loaded (including all occupants), the permissible rear
axle load (see identification plate or
vehicle documents) must not be
exceeded.
Towing equipmentCaution
When operating without a trailer,
remove the coupling ball bar.
Towing equipment audible
warning
For vehicles fitted with towing
equipment, when connected to a
trailer the pitch of the audible warning
changes upon operation of the turn
lights.
The pitch of the audible warning will
change if a turn light on the trailer or
the towing vehicle fails.
Trailer stability assist
If the system detects snaking
movements, engine power is reduced
and the vehicle / trailer combination is
selectively braked until the snaking
ceases. While the system is working, keep steering wheel as still as
possible.
Trailer stability assist is a function of
the Electronic Stability Control (ESC)
3 159.Auxiliary features
Power take-off
Activation
To activate the power take-off, with
the vehicle stationary and the engine
idling:
● Set the gearshift lever to neutral (vehicles with manual
transmission automated:
selector lever in position N).
● Depress the clutch pedal.

188Vehicle careThe filter is drained as soon as dieselfuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.
Diesel fuel system bleeding
If the fuel tank has been run dry, it will be necessary to air vent or bleed the
diesel fuel system.
Fill the tank with fuel and proceed as
follows:
1. Place a suitable container underneath the fuel filter vent
screw to collect fuel.
2. Loosen the vent screw (arrowed) by one turn.
3. Manually operate the in-line supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
4. Retighten the vent screw.
In vehicles without an in-line supply
pump, fill the tank with fuel and
proceed as follows:Caution
Do not turn ignition key to position 3 before beginning the bleeding
procedure.
Ignition switch positions 3 136.
1. Turn ignition key to position 2 and
hold for 5 seconds.
2. Turn key back to position 1 and
wait for 3 seconds.
3. Repeat Step 1 and 2 multiple times.
4. Turn key to position 3, then return
to 0.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
