DUAL-ZONE DIGITAL AIR CONDITIONING

Automatic o
peration

We recommend the use of one
of the three AUTO modes avail-
able: they provide optimised
regulation of the temperature
in the passenger compartment
according to the comfort value that you
have chosen.
These three modes automatically adjust
the air fl ow, according to the desired set-
ting, while also maintaining the desired
comfort value.

)
Press the "AUTO"
button repeat-
edly:


- a fi rst 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. When the engine is cold, the air
fl ow will reach its optimum level
progressively, taking account
of the weather and the desired
comfort level so as to avoid too
great a distribution of cold air.
On entering the vehicle, if the in-
terior temperature is much colder
or warmer than the comfort val-
ue, there is no need to change
the value displayed in order to
obtain the comfort required. The
system corrects the difference in
temperature automatically and
as quickly as possible.

1. Automatic comfort programme
This system is designed to operate ef-
fectively in all seasons, with the windows
closed.

PANORAMIC SUNROOF
Your vehicle is fi tted with a tinted glass
panoramic sunroof which increases the
light and visibility in the passenger com-
partment. Its electric blind helps control
the temperature in the passenger com-
partment.

Electric blind


Opening
Turn the dial to the left (four possible
settings).

Closing
Return the dial to the initial position.
Safety anti-pinch
If the blind encounters an obstacle dur-
ing closing, it stops and partially opens
again.
If the blind fails to close at a second
attempt, it may be necessary to force
the closing of the blind using the reini-
tialisation procedure.
The blind is controlled electrically by a
rotary dial.
In the event of contact during op-
eration of the blind, you must re-
verse its movement. To do this,
turn the dial.
When the driver operates the
dial, they must ensure that noth-
ing prevents the blind from closing
correctly.
The driver must ensure that the
passengers use the blind cor-
rectly.
Be aware of children during op-
eration of the blind.

Reinitialising the system


Following reconnection of the battery,
or in the event of a malfunction in its
operation, it may be necessary to reini-
tialise the system:


)
turn the dial to the fully closed
position,

)
then immediately press the dial, clos-
ing starts after about 10 seconds,

)
maintain pressure on the dial until
the blind has fully closed.

The anti-pinch function is inoperative
during these operations.

If the position of the blind does not
agree with the position indicated by the
dial, press the dial to open the blind to
this position.

Switching off the lighting when
switching off the ignition
When the ignition is switched off,
all of the lamps switch off immedi-
ately, except for the dipped beam
headlamps if automatic guide-
me-home lighting is activated.
In some weather conditions (e.g.
low temperature or humidity),
the presence of misting on the
internal surface of the glass of
the headlamps and rear lamps
is normal; it disappears after the
lamps have been on for a few
minutes.






Daytime running lamps

Daytime lighting, compulsory in certain
countries, which comes on automati-
cally when the engine is started making
the vehicle more visible to other users.
Manual guide-me-home lighting
Temporarily keeping the dipped beam
headlamps on after the vehicle's igni-
tion has been switched off makes the
driver's exit easier when the light is poor.

Switching on


)
With the ignition off, "fl ash" the
headlamps using the lighting stalk.

)
A further "headlamp fl ash" switches
the function off.


Switching off

The manual guide-me-home lighting
switches off automatically after a set time.



This function is assured:


- in countries where it is imposed by
regulations,
by illumination of the dipped beam
headlamps with the sidelamps and
number plate lamps; this function
cannot be deactivated.

- for other countries where it is pro-
vided,
by the use of dedicated lamps; this
function can be activated or deac-
tivated via the vehicle confi guration
menu.


The instruments and controls (instru-
ment panel, multifunction screen, air
conditioning control panel, ...) are not
illuminated, except in night mode with
manual or automatic illumination of
headlamps.

Switching on the lighting
when switching on the ignition
To reactivate the lighting control stalk, turn the ring A
to position "0"
- lighting off, then to the position of
your choice.
If the lighting is switched on manu-
ally after switching off the ignition,
there is an audible signal when a
front door is opened to warn the
driver that they have forgotten to
switch off the vehicle's lighting, with
the ignition off.
They switch off automatically after a
period which depends on the state
of charge of the battery (entry to en-
ergy economy mode).

STOP & START
The Stop & Start system puts the en-
gine temporarily on standby - STOP
mode - during stops in the traffi c (red
lights, traffi c jams, or other...). The en-
gine restarts automatically - START
mode - as soon as you want to move
off. The restart takes place instantly,
quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions as well as the noise
level when stationary.

Operation


Going into engine STOP mode
The "ECO"
warning lamp comes
on in the instrument panel and the
engine goes into standby:


- with a manual gearbox
, at speeds
below 12 mph (20 km/h), when you
put the gear lever into neutral and
release the clutch pedal, If your vehicle is fi tted with
the system, a time counter
calculates the sum of the pe-
riods in STOP mode during a
journey. It resets itself to zero every time
the ignition is switched on with the key.

- with the 6-speed electronic gear-
box system
, at a speed below
5 mph (8 km/h), when you press the
brake pedal or put the gear lever
into position N
. With the automatic gearbox
system, for your comfort dur-
ing parking maoeuvres, STOP
mode is not available for a few
seconds after coming out of re-
verse gear.
STOP mode does not affect the
functionality of the vehicle, such
as braking, power steering, for
example.
Special cases: STOP mode
unavailable
STOP mode is not invoked when:


- the driver's door is open,

- the driver's seat belt is not fastened,

- the vehicle has not exceeded 6 mph
(10 km/h) since the last engine start
using the key,

- the electric parking brake is applied
or being applied,

- the engine is needed to maintain a
comfortable temperature in the pas-
senger compartment,

- demisting is active,

- some special conditions (battery
charge, engine temperature, brak-
ing assistance, ambient tempera-
ture...) where the engine is needed
to assure control of a system.
In this case, the "ECO"
warning
lamp fl ashes for a few seconds,
then goes off. Never refuel with the engine in
STOP mode; you must switch off
the ignition with the key.

This operation is perfectly normal.
