Headlights when driving
abroad
The asymmetrical headlight beam
extends visibility at the edge of the
road on the passenger side.
However, when driving in countries
where traffic drives on the opposite
side of the road, have the headlights adjusted to prevent dazzling of
oncoming traffic. Seek the assistance
of a workshop.

signalslever up=right turn signallever down=left turn signal
If the lever is moved past the
resistance point, the turn signal is
switched on constantly.
When the steering wheel is turned
back, the turn signal is automatically
deactivated. This will not happen
when making a minor steering
manoeuvre such as lane changing.
For three flashes, e.g. when changing
lanes, press the lever until resistance is felt and then release. Move the
lever to the resistance point and hold
for longer indication.
The volume of the turn signal audible
warning is dependent upon vehicle
speed.
Switch the turn signal off manually by moving the lever to its original
position.

Entry lighting
Welcome lighting Depending upon outside light
conditions, when unlocking the
vehicle with the remote control the
hazard warning lights flash twice and
the exterior and interior lights
illuminate for 20 seconds. This
function facilitates locating the vehicle
when it is dark.
Exit lighting The low beam and reversing lights
illuminate for 30 seconds after the
driver exits the vehicle and closes the
door.Switching on
1. Switch off ignition.
2. Remove ignition key.
3. Open driver's door.
4. Pull turn signal lever.
5. Close driver's door.
If the driver's door is not closed the
lights switch off after two minutes.
Exit lighting can be deactivated by
inserting the key in the ignition switch or by pulling the turn signal lever
again while the driver's door is open.

Cooling n
Press button
n to switch on cooling.
Activation is indicated by the LED in
the button. Cooling is only functional
when the engine is running and
climate control fan is switched on.
Press button n again to switch off
cooling.
The air conditioning system cools and
dehumidifies (dries) as soon as the
outside temperature is slightly above
freezing point. Therefore
condensation may form and drip from under the vehicle.
If no cooling or drying is required,
switch the cooling system off to save
fuel. Activated cooling might inhibit
autostops.
Air recirculation system 4
Press button 4 to activate air
recirculation mode. Activation is
indicated by the LED in the button.
Press button 4 again to deactivate
recirculation mode.9 Warning
The exchange of fresh air is
reduced in air recirculation mode.
In operation without cooling the air humidity increases, so the
windows may mist up from inside.
The quality of the passenger
compartment air deteriorates,
which may cause the vehicle
occupants to feel drowsy.
In warm and very humid ambient air conditions, the windscreen might mist
up from outside, when cold air is

Driving and operating127Engine exhaust9Danger
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.
Malfunction indicator light 3 84.
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 under set driving
conditions and may take more than
15 minutes. Autostop is not available
and fuel consumption may be higher
during this period. 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 previous driving conditions did not
enable automatic cleaning, it will be
indicated by control indicator %
3 87.
% illuminates, accompanied by a
warning chime, when diesel particle
filter is full. Start cleaning process as
soon as possible.
% flashes when diesel particle filter
has reached the maximum filling level. Start cleaning process
immediately to avoid damage to the
engine. A warning chime sounds every 3 minutes until the cleaning
process is complete.
Cleaning process
To activate the cleaning process,
continue driving, keeping engine
speed above 2000 revolutions per
minute. Shift down if necessary.
Diesel particle filter cleaning is then
started.
