Stop & Start
The heating and air conditioning systems only work when the engine is
r
unning.
To
maintain a comfortable temperature
i
n the passenger compartment, you can
t
emporarily deactivate the Stop & Start
s
ystem.
For
more information on Stop & Start,

efer to the corresponding section.
In
order
for
these
systems
to
be
fully
effective,

for
regulation

the
air

for
at

5

10
minutes,

that
the
passenger
compartment
filter
is
in
good
condition
and
have
the
filter

lements
replaced
regularly.
W
e
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
compartment
(reduction
of
allergic
s
ymptoms,
bad
odours
and
greasy
deposits).
F
T
o
ensure
correct
operation
of
the
air
conditioning
system,
you
are
also
advised
to
have
i
t
checked
regularly
as
recommended
in
the
maintenance
and
warranty
guide.

the
system
does
not
produce

When
towing
the
maximum
load
on
a
steep
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.

Dual-zone digital a ir c onditioning
Automatic operation
We recommend the use of one of t
he three AUTO modes available:
t
hey provide optimised regulation of
t
he temperature in the passenger
c
ompartment according to the
c
omfort value that you have
c
hosen. F
P
ress the "AUTO"
button repeatedly:
-
a
first indicator lamp comes on; the
"
light" setting mode is selected,
-
a
second indicator lamp comes on; the
"
medium" setting mode is selected,
-
a
third indicator lamp comes on; the
"
intense" mode setting is selected.
The
air
conditioning system operates when the engine is running.
1. Automatic comfort programme
This system is designed to operate effectively i
n all seasons, with the windows closed.When
the engine is cold, the air flow will
r
each its optimum level progressively,
t
aking account of the weather and the
d
esired comfort level so as to avoid too
g
reat a distribution of cold air.
On entering the vehicle, if the interior
t
emperature is much colder or warmer
t
han the comfort value, there is no
n
eed to change the value displayed in
o
rder to obtain the comfort required.
T
he system corrects the difference
i
n temperature automatically and as
q
uickly as possible.
These
three
modes
automatically
adjust
the
a
ir
flow,
according
to
the
desired
setting,
while
a
lso
maintaining
the
desired
comfort
value.

8. Air intake / Air recirculation
F Press this button for recirculation of the interior
air.

ompartment to be isolated from exterior
o
dours
and
smoke.
F
A
s soon as possible, press this button
again
to permit the intake of outside air and
p
revent
the formation of condensation. The
i
ndicator lamp in the button goes off.
Avoid
prolonged operation in interior air
r
ecirculation mode (risk of misting and
d
eterioration of air quality). For
example, while you are away from the
v
ehicle, the passengers can still enjoy some air
c
irculation without having the engine running.
This
function is available after switching on the
i
gnition, as well as after stopping the engine.
