to your engine. .
Otherwise, have them checked by the dealer
network or a qualified workshop.
12 V battery

Air filter and passenger compartment filter
Refer to the manufacturer’s
ser vice schedule for details of the
replacement intervals for these
components.
Depending on the environment (e.g. dusty
atmosphere) and the use of the vehicle (e.g.
city driving), replace them twice as often if
necessary .
A clogged passenger compartment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Oil filter
Change the oil filter each time the
engine oil is changed.
Refer to the manufacturer’s
ser vice schedule for details of
the replacement inter val for this
component.
Particle filter (Diesel)
Depending on the version of the instrument
panel you have, the start of saturation of the
particle filter is indicated by:
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).

t
emporary illumination of
the Ser vice warning lamp,
accompanied by an audible
signal and a message that
there is a risk of blockage of the
particle filter. On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell, which
is per fectly 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.
Traffic conditions permitting, regenerate
the filter by driving at a speed of at least
37 mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this indicates
a low Diesel additive level.

refer to the corresponding section.

reserved for heavy goods vehicles.
Recommendations on storage
AdBlue® freezes below around -11°C and
deteriorates above 25°C. It is recommended
that bottles or containers be stored in a cool
place and protected from direct sunlight.
Under these conditions, the fluid can be kept
for at least a year.
If the additive has frozen, it can be used once it
has completely thawed out.
Never store bottles or containers of
AdBlue
® in your vehicle.
Procedure
Before topping up, ensure that the vehicle is
parked on a flat and level sur face.
In wintry conditions, ensure that the

Advice on care and maintenance
Recommendations on the care and
maintenance of your vehicle are given in the
Maintenance and Warranty Guide.
Matt finish
If your vehicle is coated with a clear, matt
varnish, it is essential that you take the
following instructions into account to avoid
damaging the paint, due to an inappropriate
treatment. These instructions are also valid for
the alloy wheels coated in a clear, matt varnish.
Textured paint
The textured paint reacts to light with variations
of appearance and finish that emphasise the
car's lines and form. This paint coating has
particles that remain visible and create a
unique satin relief effect. Its lightly granulated
texture gives it a surprising feel.

programmed to automatic mode, switch
off the ignition and engage first gear
(position P for the automatic gearbox) to
lock the wheels.
Check that the parking brake warning
lamps in the instrument panel come on.
The occupants must get out of the vehicle
and wait where they are safe.
If necessary, place a chock under the
wheel diagonally opposite the wheel to be
changed.

Reconnecting the (+) terminal
Do not force the lever as locking will be
impossible if the clamp is not positioned
correctly; start the procedure again.
Following reconnection
If minor problems nevertheless persist
following this operation, contact the dealer

only in the dealer network or a qualified
workshop.
The Stop & Start system may not be
operational during the trip following the
first engine start.
In this case, the system will only be
available again after a continuous
period of immobilisation of the vehicle,
a period which depends on the exterior
temperature and the state of charge of the
battery (up to about 8 hours).
