Refuelling procedure
To avoid injury and property damage when handling fuel, observe the safety rules applicable at filling stations.◄
When refuelling, insert the fuel nozzle into the filler neck. Try not to raise the nozzle during refuelling, as this leads to
► premature shut-off of the fuel supply
► reduced fuel vapour recovery
The tank can be considered full when the fuel nozzle shuts off for the first time.
