directed into the vehicle via the side
air vents.
9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in the event of
an accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door
windows and in the foot wells.
Glovebox cooler
The air conditioning system can also keep the contents of the glovebox
cool.Maintenance
Air intake
The air intake in front of the
windscreen in the engine
compartment must be kept clear to
allow air intake. Remove any leaves,
dirt or snow.

intake.

112Driving and operating
Service modePress button i for 5 seconds to put
the vehicle into service mode. The indicator light will illuminate. When
service mode has been activated, the
air suspension master switch must be turned off.
To exit service mode, press button
i again for 5 seconds.
Fault If a fault is detected, i button will
flash intermittently. If the service
mode has been activated and there is a fault h, S and R buttons will flash
simultaneously.
Have the cause of the fault remedied by a workshop.Engine exhaust9 Danger
Engine exhaust gases contain
poisonous carbon monoxide,
which is colourless and odourless and could be fatal if inhaled.
If exhaust gases enter the interior
of the vehicle, open the windows.
Have the cause of the fault
rectified by a workshop.
Avoid driving with an open load
compartment, otherwise exhaust
gases could enter the vehicle.
Diesel particle filter
The diesel particle filter system filters
harmful soot particles out of the
exhaust gases. The system includes
a self-cleaning function that runs
automatically during driving without
any notification. The filter is cleaned
by periodically burning off the soot
particles at high temperature. This
process takes place automatically
and the emission of smells and
smoke during this process is normal.
Under certain driving conditions, e.g.
short distances, the system cannot
clean itself automatically.
If cleaning of the filter is required and if previous driving conditions did not
enable automatic cleaning, it will be
indicated by illumination of control
indicator A 3 79. Seek the
assistance of a workshop immediately.
Catalytic converter
The catalytic converter reduces the
amount of harmful substances in the
exhaust gases.

Vehicle care139Diesel 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.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
Wiper blade replacement Wiper blades on the windscreenLift wiper arm, press retaining clip
towards wiper arm and detach wiper
