240 OperationAt the gas stationRefueling
The fuel filler flap is located on the 
right-hand side of the vehicle towards the 
rear. Locking/unlocking the vehicle with 
the SmartKey automatically locks/unlocks 
the fuel filler flap.
Remove the SmartKey from the starter 
switch.
Open the fuel filler flap by pushing at 
the point indicated by arrow.
The fuel filler flap opens.
Turn fuel cap counterclockwise and 
hold on to it until possible pressure is 
released.
Take off cap and set it in the recess on 
the fuel filler flap.

Warning!
G
Gasoline is highly flammable and poisonous. 
It burns violently and can cause serious 
injury. Whenever you are around gasoline, 
avoid inhaling fumes and skin contact, 
extinguish all smoking materials. Never 
allow sparks, flame or smoking materials 
near gasoline! 
iOnly use premium unleaded gasoline 
with a minimum Posted Octane Rating 
of 91 (average of 96 RON/86 MON). 
Information on gasoline quality can 
normally be found on the fuel pump.Warning!
G
Overfilling of the fuel tank may create 
pressure in the system which could cause a 
gas discharge. This could cause the gas to 
spray back out when removing the fuel 
pump nozzle, which could cause personal 
injury.

freezing point. Failure to do so could 
result in damage to the washer 
system/reservoir.The washer fluid reservoir is located in the 
trunk underneath the floor on the left hand 
side.
