i
s running. To maintain a comfortable
t
emperature in the passenger
c
ompartment, you can temporarily
d
eactivate the Stop & Start system (see
t
he corresponding section).

W

recommend
the
use
of
a
combined
passenger
compartment
filter.
Thanks
to
its
s
pecial active additive, it contributes to the purification of the air breathed by the
occupants
and
the
cleanliness
of
the
passenger

(reduction
of
allergic
s
ymptoms,
bad
odours
and
greasy

also
advised
to
have

checked
regularly
as

When

the
maximum
load

gradient
in
high
temperatures,
switching
off
the
a
ir
conditioning
increases
the
available
engine
power
and
so
improves
the
towing
ability. The condensation created by the air
conditioning
results in a discharge
o
f water under the vehicle which is
per fectly normal.
If after an extended stop in sunshine,
t
he interior temperature is very
h
igh, first ventilate the passenger
c
ompartment for a few moments.
Put the air flow control at a setting high
e
nough to quickly change the air in the
p
assenger
c
ompartment.
The air conditioning system does not
c
ontain chlorine and does not present
any danger to the ozone layer.
