Several warning and indicator lamps will light up briefly as a functional check when the ignition is
switched on. They will switch off after a few seconds.
Natural gas engines
Things to note: if the vehicle is parked for an extended period directly after refuelling, it may well
occur that the pointer for the natural gas engine does not indicate the fuel level shown directly after
refuelling. This does not mean that there is a leak in the system but but rather that, for technical
reasons the pressure has been decreased in the natural gas tank.
The small arrow next to the petrol pump symbol ⇒ Fig. 115 in the display instrument shows
you the side of the vehicle on which the tank flap is located.
Only applies for vehicles with a fuel gauge in the instrument cluster ⇒ Fig. 115.
Only applies for vehicles with a fuel gauge in the instrument cluster display ⇒ Fig. 116.
Filling the tank with petrol
a)
b)
Driving the vehicle when the fuel level is too low could lead to your vehicle breaking down in
traffic, accidents and serious injuries.
•When the fuel level is too low, the fuel supply to the engine could be irregular, especially
when driving up or down hills and inclines.
•The steering, all driver assist systems and brake assist systems will not function if the
engine sputters or stops completely due to a lack of fuel or irregular fuel supply.
•Always fill the tank when it is still 1/4 full. This reduces the risk of running out of fuel and
breaking down.
WARNING
•To avoid damage to your vehicle, always observe the indicator lamps and associated
warning texts.
•Do not run the tank empty. Irregular filling periods can cause backfiring and allow unburnt
fuel to enter the exhaust system. This could cause damage to the catalytic converter!
NOTICE
a)
b)

Switch off the engine, ignition and the mobile telephone before filling the tank and leave them
switched off during the process ⇒.
Please read and follow the instructions for the natural gas refuelling system.
The vehicle is not constructed for use with Liquefied Natural Gas (LNG) ⇒. Before refilling with
natural gas check that you are using the correct fuel ⇒ Fuel.
Opening the tank cap
The gas filler neck is located under the tank flap next to the petrol filler neck.
•The tank flap is at the rear of the vehicle on the right.
•Open the tank cap by the moulding to the rear.
Filling the tank
At very high ambient temperatures, the overheating protection function for the natural gas refuelling
system could switch off automatically.
•Remove the cap ⇒ Fig. 118① from the gas filler neck ②.
•Place the filler coupling for the refuelling system on the gas filler neck. Please refer to natural
gas refuelling system operating manual.
•The fuel tank is full when the compressor for the refuelling system switches off automatically.
•To end the refuelling procedure press the stop button on the refuelling system.
Closing the tank cap
•Check whether seal ⇒ Fig. 118③ on the gas filler neck has slipped onto the filler coupling.
Place the seal back in the gas filler neck as necessary.
•Push the cap ① onto the gas filler neck.
•Close the tank flap. The tank flap must be flush with the vehicle bodywork.
The filling couplings for the natural gas refuelling systems can be of various different
designs. Please ask for assistance from trained personnel if you are unsure of how to use the
system.
Noises which you may hear while refuelling are normal and do not indicate that the system is
malfunctioning.
The natural gas system in your vehicle is suitable for use with small compressors (slow fill)
and large compressors (fast fill).
Capacities
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Fuel tank capacity
Petrol enginesapprox 35.0 l, of which 4.0 l reserve.
Natural gas engineNatural gas: approx. 11.0 kg of which reserve approx. 1.5 kg.
Petrol: approx. 10.0 l of which reserve approx. 5.0 l
Checks when filling the tank
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Checklist
Never carry out any work on the engine or in the engine compartment if you are not familiar with
the necessary procedures and the general safety requirements or if the correct operating
Natural gas is highly explosive and inflammable. Failure to refuel properly with natural gas
could result in accidents, serious burns and other injuries.
•Lock the fuel filler nozzle correctly before refuelling natural gas. Stop refuelling
immediately if you start to smell gas.
WARNING
Your vehicle is not suitable for use with Liquefied Natural Gas and must not be filled up or
driven with Liquefied Natural Gas. Liquefied Natural Gas can cause an explosion in the
natural gas tank and serious injuries as a consequence.
WARNING

•You will need to depress the brake pedal more vigorously than normal as the brake servo is not
working. Do not drive too close to the towing vehicle.
•Read and comply with the information and notes in the owner's manual of the towing vehicle.
Notes for the driver of the towing vehicle
•Accelerate carefully and gently. Avoid any sudden driving manoeuvres.
•Brake earlier than normal by pressing lightly on the brake pedal.
•Read and comply with any information and notes in the owner's manual of the towed vehicle.
