I N S T R U M E N T S a n d C O N T R O L S Airbags If this comes on, it indicates
the occurrence of a fault in
one of the airbag or seat belt
pretensioner systems.
Maximum coolant temperature
If this comes on, it indicates
that the temperature in the
cooling system is too high.
Stop the vehicle as soon as
it is safe to do so.
Low fuel level When the tank is full, all the
bars are lit up.
If the fuel low warning lamp
comes on accompanied by
an audible signal and a message on
the multifunction screen, there are
approximately 7 litres of fuel remain-
ing in the tank and 2 or 3 bars fl ash
in the instrument panel.
When the last bar goes out, there
are approximately 2 litres of fuel re-
maining in the tank.
Top up with fuel as soon as possible
to avoid running out.
This warning lamp comes on each
time the ignition is switched on, until
suffi cient fuel is added.
A control located on the panel to the
right of the steering wheel allows
you to open the fuel fl ap from inside
the vehicle.
Do not continue driving until you run
out of fuel as this may cause dam-
age to the emisions control and fuel
injection systems. Battery charge
If this comes on, it indi-
cates the occurrence of a
fault in the battery charging
circuit (dirty or loose termi-
nals, slack or cut alternator
belt, ...).
Door open A door, the boot or the rear
screen is open:
- if the speed is below 6 mph (10 km/h), this warning lamp comes on continuously,
-
if the speed is higher than 6 mph (10 km/h),
this warning lamp comes on continuously,
accompanied by an audible signal.
Seat belt not fastened/
unfastened
This warning lamp informs
you if the driver’s or front
passenger’s seat belt is
not fastened (depending
on model), and if the front
passenger’s (depending on
model) or the second row
passengers’ seat belts are
unfastened. The lit up positions repre-
sent those whose seat belts are not
fastened/unfastened. Seat belts unfastened during the
journey:
- the point corresponding to the
seat position with seat belt un-
fastened lights up between 0 and
approximately 12 mph (20 km/h).
Above 12 mph (20 km/h), it fl ash-
es accompanied by an audible
signal for around 120 seconds.
The audible signal stops when
the ignition is switched off or if a
door is opened.
Depending on model, the front pas-
senger seat may be fi tted with a
presence sensor; the correspond-
ing warning lamp will only come on
if the seat is occupied and the seat
belt not fastened.
Driver’s or front passenger’s seat belt
not fastened with presence sensor:
- the warning lamp lights up be-
tween 0 and approximately
12 mph (20 km/h). Above 12 mph
(20 km/h), it fl ashes accompa-
nied by a message on the mul-
tifunction screen and an audible
signal for around 120 seconds.

front passenger’s seat belt not fas-
tened without presence sensor:
- when the ignition is switched on, the points corresponding to the seat po-
sitions with seat belts not fastened
remain lit up for 30 seconds.

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 win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is exces-
sive, air 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's servic-
ing schedule (see "Maintenance and
Warranty Guide").
Air circulation
Air vents on the fl oor underneath the
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face 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
a number of sensors (sunlight sen-
sor, outside temperature sensor...)
that relieve you of the need to make
frequent adjustments outside the
displayed temperature.
Be careful not to obstruct the sun-
light sensor, located on the dash-
board behind the instrument panel.

Model with rear foglamp only Model with front and rear
foglamps In good or rainy weather, both day
and night, the front foglamps and
the rear foglamp are prohibited. In
these situations, the power of their
beams may dazzle other drivers.
They should only be used in fog or
snow.
In these weather conditions, it is
your responsibility to switch on the
foglamps and dipped headlamps
manually as the brightness sensor
may detect suffi cient light.
Do not forget to switch off the front
foglamps and the rear foglamp
when they are no longer necessary.
Lighting on buzzer
On switching off the ignition, all of
the lamps turn off immediately, ex-
cept for dipped beam if guide-me-
home lighting is activated.
To reactivate the lighting control, ro-
tate ring

off, then to the desired position.
On opening the driver's door a
temporry audible signal warns the
driver that the lamps are on.
The lamps, with the exception of
the sidelamps, switch off automati-
cally after thirty minutes to prevent
discharging of the battery.
