correspond to the methane level in
the cylinders. As the fuel level
diminishes, the bars in the CNG fuel
gauge disappear.
CNG and the one remaining bar will
flash if the methane level in the
cylinders is low.

Service display
Service display is available in
vehicles with Multifunction version of the Driver Information Centre (DIC)3 85.
When the ignition is switched on, the remaining distance before the next
service is due is shown briefly. Based
on driving conditions, the interval at
which a service will be indicated can
vary considerably.
When the remaining distance before
the next service is less than
1,250 miles, Serv. appears in the DIC.
The service reminder is repeated
after every additional 125 miles and becomes more frequent when the
remaining distance is below
125 miles.
The vehicle needs a service. Seek the
assistance of a workshop.
The remaining distance to the next
service may also be viewed in the DIC by selecting SERVICE from the
settings menu options 3 85.
Resetting the service display After a service, the service display
must be reset by a workshop.

Vehicle care133Vehicle storageStorage 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, well ventilated 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.
136Vehicle careEngine coolantThe coolant provides freeze
protection down to approx. -28 °C. In
northern countries with very low
temperatures, the factory filled
coolant provides frost protection
down to approx. -37 °C.Caution
Only use approved antifreeze.
Coolant level
Caution
Too low a coolant level can cause engine damage.
If the cooling system is cold, the
coolant level should be between the
MIN and MAX mark. Top up if the
level is low.
9 Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
To top up use a 1:1 mixture of
released coolant concentrate mixed
with clean tap water. If no coolant
concentrate is available, use clean
tap water. Install the cap tightly. Have
the coolant concentration checked
and have the cause of the coolant
loss remedied by a workshop.
Power steering fluid
If the fluid level in the reservoir falls
below the MIN mark consult a
workshop.
If an unusual noise sounds during
steering or the power steering reacts
conspicuously, seek the assistance of
a workshop.
