218 Fuel and filling the tank
– Hook the cap onto the open flap ⇒ page 217, fig. 208.
Closing the tank cap
– Screw on the tank cap clockwise until it cannot be turned
further.
– Press the left side of the flap to close it (you should hear
it click into place).
When the automatic filler nozzle is operated correctly it will switch
itself off as soon as the tank is "full". Do not try to put in more fuel
after the nozzle cuts out, as this will fill the expansion chamber in
the fuel tank.
The correct fuel grade for your vehicle is given on a sticker on the
inside of the tank flap. Further notes on fuel ⇒ page 217.
The tank capacity of your vehicle is given in the Technical data
section ⇒ page 279.
WARNING
Fuel is highly inflammable and can cause serious burns and other
injuries.
For safety reasons always switch off the auxiliary heating*
before refuelling the vehicle.
For safety reasons we do not recommend carrying a spare fuel
canister in the vehicle. The canister could become damaged in an
accident and leak.
Observe all relevant statutory regulations on using, storing and
transporting spare fuel canisters.
When filling your tank or a spare fuel canister with fuel, do not
smoke and keep away from naked flames. Risk of explosion!
If, in exceptional circumstances, you have to carry a spare fuel
canister, please observe the following warnings:
Never fill fuel into the spare fuel canister with the canister
placed in or on top of the vehicle. An electrostatic charge could
WARNING (continued)
build up during filling, causing the fuel vapour to ignite. Danger
of explosion. Always place the canister on the ground to fill it.
Insert the filler nozzle as far as possible into the spare fuel
canister.
If the spare fuel canister is made of metal, the filler nozzle
must be in contact with the canister during filling. This helps
prevent an electrostatic charge building up.
Make sure you never spill fuel in the vehicle or in the luggage
compartment. Fuel vapour is explosive. Risk of fatal accident!
Caution
Remove any fuel spills from the paintwork immediately.
Never run the tank completely dry. If there is an irregular fuel
supply, misfiring can occur. As a result unburnt fuel can enter the
exhaust system and cause damage to the catalytic converter(s).
For the sake of the environment
Do not try to put in more fuel after the automatic filler nozzle has
switched off; this may cause the fuel to overflow if it becomes
warm.
