150Climate controlDirect the flow of air by tilting and
swivelling the slats.
To close the vent, swivel the slat
sideways.9 Warning
Do not attach any objects to the
slats of the air vents. Risk of
damage and injury in case of an
accident.
Fixed air vents
Additional air vents are located
beneath the windscreen and door windows and in the foot wells.
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.
Cabin air filter
Change filter regulary for maximum
effect.
Air conditioning regular
operation
In order to ensure continuously
efficient performance, cooling must
be operated for a few minutes once a
month, irrespective of the weather
and time of year. Operation with
cooling is not possible when the
outside temperature is too low.
Service For optimal cooling performance, it is
recommended to annually check the
climate control system, starting
three years after initial vehicle
registration, including:
● functionality and pressure test
● heating functionality
● leakage check
● check of drive belts
● cleaning of condenser and evaporator drainage
● performance check
● cabin air filter check
160Driving and operating● If the vehicle is on a levelsurface or uphill slope, engage
first gear or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows and the sunroof.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
button. Turn the steering wheel until the steering wheel lock is
felt to engage.
For vehicles with automatic
transmission, the key can onlybe removed when the selector
lever is in position P.
● Lock the vehicle by pressing the
button on the door handle or the
button e on the remote control.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 231.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low load or run in neutral for
approx. 30 seconds before
switching off, in order to protect
the turbocharger.
Note
In the event of an accident with
airbag deployment, the engine is
turned off automatically if the vehicle
comes to a standstill within a certain time.
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.
Exhaust filter
The exhaust filter is a particle filter for diesel and petrol engines.
Driving and operating161Automatic cleaning processThe exhaust filter system filters 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 up to
25 minutes. Typically it needs
between 7 and 12 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.
System requires cleaning Under certain conditions, e.g. driving
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 a warning message in
the Driver Information Centre.A warning message appears when
exhaust filter is full. Start cleaning
process as soon as possible.
A warning message also appears
when exhaust filter has reached the
maximum filling level. Start cleaning
process immediately to avoid
damage to the engine.
Activate self-cleaning process
Cleaning process is completed more
quickly at high engine speeds and loads. Therefore, drive in lower gears
than normal, and use manual gear
selection on vehicles with automatic
transmission. Usage of electrical
consumers like air conditioning and
heated windows to increase engine
load supports cleaning process.Caution
If possible, do not interrupt
cleaning process. Drive until
cleaning is completed to avoid the
need for service or repair by a
workshop.
Vehicles with petrol engine
To activate cleaning process,
continue driving, keep engine speed
above 2500 rpm. Shift down if
necessary.
Drive dynamically at different engine
speeds. Use engine brake for
deceleration, if possible.
Keep on driving until self-cleaning
operation is complete and the display
message disappears.Vehicles with diesel engine
To activate cleaning process,
continue driving, keep engine speed
above 2000 rpm, ideally and
continuously around 2500 rpm. Shift
down if necessary.
Keep on driving until self-cleaning
operation is complete and the display message disappears.
