Practical information

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).
- fixed illumination of the particle filter warning lamp, accompanied
by an audible signal and a
message that there is a risk of
blockage of the particle filter,
or
-
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.
For more information on Checking levels ,
refer to the corresponding section.
