Refueling
Always switch off the engine before refu-
eling; otherwise, fuel cannot be added to 
the tank and a message will be displayed.<
Take all precautionary measures and 
observe all applicable regulations when 
handling fuel. Do not carry any spare fuel con-
tainers in your vehicle. They can develop a leak
