When you have filled the tank:
F put the cap back in place,
F turn the key to the right, then remove it

F close the flap.
If you have put in the wrong fuel for
the engine of your vehicle, you must
have the fuel tank drained and filled
with the correct fuel before starting
the engine.
Fuel supply cut-off
Your vehicle is fitted with a safety system that
cuts off the supply of fuel in the event of an
impact.
Diesel
Particle filter
The start of saturation of the particle
filter is indicated by the fixed
illumination of this warning lamp
accompanied by a warning message
in the screen (if a display screen is
fitted).
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 40 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates a
low additive level.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burnt" smell, which
is normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
