Air conditioning
To ensure that your system operates
correctly, it is recommended to have
it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the windows
closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
ventilate the passenger compartment
by opening the windows for a few
moments, then close them again.
The air conditioning operates by using
power from the engine. This results in
a slight increase in fuel consumption.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air fl ow
and direction (up-down, right-left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

SEAT BELTS
Front seat belts
The front seat belts are fi tted with
a pretensioning system and force
limiter.
This system improves safety in the
front seats in the event of a front
impact. Fastening

 Pull the belt down in front of you
in a steady movement, making
sure that it does not become
twisted.

 Press the fastening into its buckle.

 Check that it is properly secured
and that the automatic locking
mechanism operates correctly
by pulling sharply on the belt
strap.

 The abdominal part of the strap
should be positioned as low
down as possible in the lap and
as tight as possible.

 The chest part should be posi-
tioned if possible in the channel
of the shoulder.
Each belt has a reel that adjusts its
length automatically to the girth of
the seat occupant.
Depending on the seriousness of the
impact, the pretensioning system in-
stantly tightens the seat belt against
the body of the occupant.
The pretensioning seat belts are ac-
tive when the ignition is on.
The force limiter reduces the pres-
sure of the seat belt against the
chest of the occupant, so increasing
their protection.
