pollen and spores from the air
entering the vehicle through the air
intake.
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 outside
temperature is too low.
Service For optimal cooling performance, it isrecommended that the climate control
system be checked annually, 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
Driving and operating103Starting and operating
New vehicle running-in Do not brake unnecessarily hard for
the first few journeys.
During the first drive, smoke may
occur because of wax and oil
evaporating off the exhaust system.
Park the vehicle in the open for a
while after the first drive and avoid
inhaling the fumes.
During the running-in period fuel and
engine oil consumption may be
higher and the cleaning process of the diesel particle filter may take
place more often. Autostop may be inhibited to allow for charging the
battery.

features are implemented as part of
the stop-start system.
Restarting the engine
Manual transmission
The selector lever must be in neutral
to enable an automatic restart.
Depress the clutch pedal to restart the
engine.
Manual transmission automated
If the lever is in position N, select
another gear, otherwise release the
brake pedal or move the lever to +, –
or R to enable an automatic restart.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop
during the restart may be noticeable.
Restarting the engine with the
key When one of the following conditions
occurs during an Autostop, the
engine will need to be restarted
manually using the key.
Driving and operating111
R=Reverse gear.
Engage only when vehicle is
stationary. The transmission
display shows "R" when
reverse gear is engaged.+=Shift to a higher gear.-=Shift to a lower gear.
Starting-off
When the engine is started, depress
the foot brake and move the selector
lever towards + to engage first gear.
Shift to a higher or lower gear by
moving selector lever to + or -.
Gears can be skipped by moving the selector lever repeatedly at short
intervals.
The driver will be alerted to an
incorrect gear selection by an audible warning chime in conjunction with a
message in the Driver Information
Centre 3 80. The system will
downshift, selecting the most
appropriate gear automatically.
If R is selected, reverse gear is
engaged. The vehicle starts to move
when the foot brake is released. To
start off quickly, release the foot brake
and accelerate immediately after
engaging a gear.
Move the selector lever towards A/M
to engage automatic mode; the
transmission shifts to other gears
automatically, dependent on driving
conditions.
To engage manual mode, move the
selector lever towards A/M. The
current gear will appear in the
transmission display.
Stopping the vehicle
In automatic or manual mode,
first gear is engaged and the clutch is
released when the vehicle is stopped. In R, reverse gear remains engaged.
When stopping on gradients, engage parking brake or depress the foot
brake. To prevent overheating of the
clutch, an intermittent audible
warning chime may sound as a signal
to depress the foot brake or apply the
parking brake.
Switch off engine if stopping for a
lengthy period, e.g. in traffic jams.When the vehicle is parked and the
driver's door is opened, a warning
chime will sound if neutral is not
selected or the foot brake has not
been depressed.
Engine braking Automatic mode
When driving downhill, the manual
transmission automated does not
shift into higher gears until a fairly
high engine speed has been reached.
It shifts down in good time when
braking.
Manual mode
To utilise the engine braking effect, select a lower gear in good time when driving downhill.
120Driving and operatingFuel
Fuel for petrol engines Only use unleaded fuel that complies
with European standard EN 228 or E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 166. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly increases fuel consumption.Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled combustion and engine damage.
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
In countries outside the European
Union use Euro-Diesel fuel with a
sulphur concentration below 50 ppm.
Caution
Use of fuel that does not comply to EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage and may affect
your warranty.
Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel for natural gas
operation
Use natural gas with a methane
content of approx. 78 - 99 %. L-gas
(low) has approx. 78 - 87 % and H-gas (high) has approx. 87 - 99 %. Biogaswith the same methane content can
also be used if it has been chemically
prepared and desulphurised.
Only use natural gas or biogas that
complies with DIN 51624.
Liquid gas or LPG must not be used.

that no dirt can get under it and
scratch the glass.
Clean smearing wiper blades with a
soft cloth and window cleaner.
Glass panel
Never clean with solvents or abrasive
agents, fuels, aggressive media (e.g.
paint cleaner, acetone-containing
solutions etc.), acidic or highly
alkaline media or abrasive pads. Do
not apply wax or polishing agents to
the glass panel.
Wheels and tyres Do not use high-pressure jet
cleaners.Clean rims with a pH-neutral wheel
cleaner.
Rims are painted and can be treated
with the same agents as the body.
Paintwork damage Rectify minor paintwork damage with
a touch-up pen before rust forms.
Have more extensive damage or rust
areas repaired by a workshop.
Underbody
Some areas of the vehicle underbody
have a PVC undercoating while other critical areas have a durable
protective wax coating.
After the underbody is washed, check
the underbody and have it waxed if
necessary.
Bitumen/rubber materials could
damage the PVC coating. Have
underbody work carried out by a
workshop.
Before and after winter, wash the
underbody and have the protective
wax coating checked.Natural gas system
Do not direct the steam jet or high-
pressure jet towards natural gas
system components. It is particularly
important to protect the natural gas
tank and the pressure valves on the
vehicle underbody and the bulkhead
in the engine compartment.
These components must not be
treated using chemical cleaners or
preservatives.
Have components of the natural gas
system cleaned by a workshop
authorised to carry out maintenance
of natural gas vehicles.
