As soon as the natural gas tanks are
empty, petrol operation is
automatically engaged. Control
indicator Y illuminates in the Driver
Information Centre 3 89 until the
ignition is switched off.
When switching automatically
between petrol or gas operation, a
brief delay of engine tractive power
may be noticeable.
Every six months run the petrol tank
down until control indicator §
illuminates and then refuel. This is
necessary to maintain fuel quality as
well as system function necessary for
petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Refuelling
Fuel filler flap is located at left rear
side of vehicle.9 Danger
Before refuelling, switch off engine
and any external heaters with
combustion chambers. Switch off
any mobile phones.
Follow the operating and safety
instructions of the filling station
when refuelling.
9 Danger
Fuel is flammable and explosive.
No smoking. No naked flames or
sparks.
If you can smell fuel in your
vehicle, have the cause of this
remedied immediately by a
workshop.
Caution
In case of misfuelling, do not
switch on ignition.
Release the fuel filler flap by pulling
the flap by hand.
Insert ignition key into fuel filler cap
and turn anticlockwise to unlock.
To remove fuel filler cap, rotate
anticlockwise.
Caution
To avoid damage, do not attempt
to operate the sliding side door
when the fuel filler flap is open.
Driving and operating135Notice
Depending on model, the sliding
side door may be fitted with a safety
system that prevents the door from
being opened fully when the fuel
filler flap is open.
Sliding side door 3 25.
The fuel filler cap can be retained in
the bracket on the fuel filler flap.
To refuel, fully insert the pump nozzle
and switch it on.
After automatic cut-off, the tank can be topped up by operating the pump
nozzle a maximum of two more times.
Caution
Wipe off any overflowing fuel
immediately.
To close, replace fuel filler cap and
turn clockwise.
Insert ignition key into fuel filler cap
and turn clockwise to lock, then
remove key.
Close the fuel filler flap.
Natural gas refuelling
Open the fuel filler flap.
9 Warning
Refuel only with a maximum
output pressure of 250 bar. Use
only temperature compensated
filling stations.
The refuelling procedure must be
completed, i.e. the filler neck must be vented.
The capacity of the natural gas tank
depends on outside temperature,
filling pressure and type of refuelling
system.
Close the fuel filler flap after
refuelling.

140Vehicle careCaution
When transporting the vehicle on
a train or on a recovery vehicle, the
mud flaps might be damaged.
Vehicle storage
Storage for a long period of time
If the vehicle is to be stored for several months:
● Wash and wax the vehicle.
● Have the wax in the engine compartment and underbody
checked.
● Clean and preserve the rubber seals.
● Fill up fuel tank completely.
● Change the engine oil.
● Drain the washer fluid reservoir.
● Check the coolant antifreeze and
corrosion protection.
● Adjust tyre pressure to the value specified for full load.
● Park the vehicle in a dry, wellventilated place. Engage first or
reverse gear to prevent the
vehicle from rolling.
● Do not apply the parking brake.
● Open the bonnet, close all doors and lock the vehicle.
● Disconnect the clamp from the negative terminal of the vehicle
battery. Beware that all systems
are not functional, e.g. anti-theft
locking system.
Putting back into operation
When the vehicle is to be put back into operation:
● Connect the clamp to the negative terminal of the vehicle
battery. Activate the electronics
of the power windows.
● Check tyre pressure.
● Fill up the washer fluid reservoir.
● Check the engine oil level.
● Check the coolant level.
● Fit the number plates if necessary.End-of-life vehicle recovery
Information on end-of-life vehicle
recovery centres and the recycling of
end-of-life vehicles is available on our website. Only entrust this work to an
authorised recycling centre.
Natural gas vehicles must be recycled by a service centre authorised for
natural gas vehicles.
174Vehicle carePaintwork damageRectify 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 gastank and the pressure valves on the vehicle underbody and the bulkheadin 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.
Towing equipment Do not clean the coupling ball bar with
a steam-jet or high-pressure jet
cleaner.
Interior care
Interior and upholstery Only clean the vehicle interior,
including the instrument panel fascia
and panelling, with a dry cloth or
interior cleaner.
Clean the leather upholstery with
clear water and a soft cloth. In case of
heavy soiling, use leather care.The instrument cluster and the
displays should only be cleaned using
a soft damp cloth. If necessary, use a weak soap solution.
Clean fabric upholstery with a
vacuum cleaner and brush. Remove
stains with an upholstery cleaner.
Clothing fabrics may not be
colourfast. This could cause visible
discolourations, especially on light-
coloured upholstery. Removable
stains and discolourations should be
cleaned as soon as possible.
Clean seat belts with lukewarm water
or interior cleaner.Caution
Close Velcro fasteners as open
Velcro fasteners on clothing could damage seat upholstery.
The same applies to clothing with
sharp-edged objects, like zips or
belts or studded jeans.
