WARNING
Pay attention to any legal requirements if you do carry a spare
canister in the vehicle. We do not recommend carrying any fuel
canisters in your vehicle for safety reasons. The canister can be
damaged in the event of an accident and fuel may leak out.
Caution
•
Remove any fuel which has spilled onto the paintwork of your vehicle
immediately. This particularly applies to biodiesel - risk of paint damage!
•
Vehicles fitted with catalytic converter should never be allowed to let
the fuel tank to run completely empty. An irregular supply of fuel to the
engine can result in misfiring and unburnt fuel may get into the exhaust
system, which may result in overheating and damage to the catalytic
converter.

The fuel tank is full just as soon as the pump nozzle switches off for the
first time, provided the nozzle has been operated properly. You should not
continue refuelling - otherwise the expansion chamber in the fuel tank will
also be filled with fuel. Fuel might flow out of the tank when it heats up.
