Petrol
First read and observe the introductoryinformation and safety warnings⇒
Introduction
Vehicles with a petrol engine must be run on unleaded petrol. Fuels with a maximum ethanol
content of 10yb(\f can be used for refuelling ⇒.
The petrol grades differ with respect to the octane number. The vehicle may be filled with petrol that
has a higher octane number than the engine requires. However, this does not provide any
advantage in terms of fuel consumption or engine output.
The fuel quality affects the running properties, performance and service life of the engine. You
should therefore use fuel that already contains suitable service additives if possible ⇒.
Information on the fuel standards can be found in the chapter on fuel standards ⇒ Fuel standards.
Incorrect handling of fuel can cause explosions, fire, serious burns and other injuries.
•Switch off the auxiliary heater⇒ Auxiliary heater and ventilation, the engine, the
ignition, your mobile phone and other wireless equipment while refuelling.
•Do not get into the vehicle to avoid electrostatic discharge.
•Make sure that the tank cap is closed properly and no fuel can escape.
•Comply with any relevant safety information and legislation concerning the handling of
fuels.
WARNING
Fuel may run out of the fuel canister. This could cause fire and injuries.
•Do not carry fuel canisters in the vehicle.
CAUTION
Incorrect refuelling can lead to damage to the vehicle.
•Only use fuels that have been approved for the vehicle.
•Do not use fuels containing metals and only use approved additives.
•Spilt fuel should be removed from all vehicle components immediately.
