Safety warnings regarding fuel
handling
WARNING
Fuel is highly ammable and can cause seri-
ous burns and other injuries.
●
When refuelling, turn o the engine and
turn o the ignition for safety reasons.
●
The fuel system of PHEV models is pressur-
ized to prevent petrol vapours from escaping
into the atmosphere.
●
Do not smoke when lling the fuel tank or
a canister. Naked ames are forbidden in the
vicinity due to the risk of explosion.
●
Observe legislation governing the use,
storage and carrying of a spare fuel canister
in the vehicle.
●
For safety reasons we do not recommend
carrying a spare fuel canister in the vehicle.
In an accident the canister could be dam-
aged and could leak.
●
If, in exceptional circumstances, you have
to carry a spare fuel canister, please observe
the following points:
–
Never ll fuel into the spare fuel canister
if it is inside or on top of the vehicle. This
could cause an explosion. Always place the
canister on the ground to ll it.
–
Insert the lling nozzle as far as possible
into the spare fuel canister.
–
If the spare fuel canister is made of
metal, the lling nozzle must be in contact
with the canister during lling. This helps
prevent an electrostatic charge building
up.
–
Never spill fuel in the vehicle or in the
luggage compartment. Fuel vapour is ex-
plosive. Risk of fatal accident!
NOTICE
●
If any fuel is spilt onto the vehicle, it should
be removed immediately. It could otherwise
damage the paintwork.
●
Never run the tank completely dry. The
catalytic converter can be damaged.
For the sake of the environment
Do not overll the fuel tank, it may cause the
fuel to overow if it becomes warm.
Note
There is no emergency mechanism for the
manual release of the fuel tank ap. If nec-
essary, request assistance from specialised
personnel.
