RECOMMENDATIONS FOR VENTILATION AND AIR
CONDITIONING
In order for these systems to be fully effective, follow the operation and
maintenance guidelines below:


)
To obtain an even air distribution, take care not to obstruct the exterior air
intake grilles located at the base of the windscreen, the nozzles, the vents
and the air outlets, as well as the air extractor located in the boot.

)
Do not cover the sunshine sensor, located on the dashboard; this is
used for regulation of the digital air conditioning system.

)
Operate the air conditioning system for at least 5 to 10 minutes, once or
twice a month to keep it in perfect working order.

)
Ensure that the passenger compartment fi lter is in good condition and
have the fi lter elements replaced regularly (refer to the "Checks" sec-
tion).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its special active additive, it contributes to the purifi cation of
the air breathed by the occupants and the cleanliness of the passenger
compartment (reduction of allergic symptoms, bad odours and greasy
deposits).

)
To ensure correct operation of the air conditioning system, you are
also advised to have it checked regularly as recommended in the
Maintenance and Warranty Guide.

)
If the system does not produce cold air, switch it off and contact a
CITROËN dealer or a qualifi ed workshop.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning increases the available engine power and
so improves the towing ability.
If after an extended stop in sun-
shine, the interior temperature is
very high, fi rst ventilate the pas-
senger compartment for a few
moments.
Put the air fl ow control at a set-
ting high enough to quickly
change the air in the passenger
compartment.
The air conditioning system
does not contain chlorine and
does not present any danger to
the ozone layer.

The condensation created by
the air conditioning results in a
discharge of water under the ve-
hicle which is perfectly normal.



Stop & Start
The heating and air conditioning systems only work when the engine is run-
ning. To maintain a comfortable temperature in the passenger compartment,
you can temporarily deactivate the Stop & Start system (see "Driving").

TYRE UNDER-INFLATION
DETECTION
System which automatically and continu-
ously checks the pressure of the tyres
while driving.
Sensors fi tted in each valve trigger a
warning in the event of problem (speed
above 12 mph (20 km/h)).
This warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal,
to identify the wheel concerned.

Under-infl ated tyre
The STOP
warning lamp
comes on and/or this warn-
ing lamp is displayed on the
instrument panel, accompa-
nied by an audible signal and
a message in the screen iden-
tifying the wheel concerned.


)
Stop as soon as it is safe to do so,
avoiding any sudden movement of
the steering wheel and the brakes.

)
Repair or change the damaged
wheel (punctured or very defl ated
tyre), and have the tyre pressure
checked as soon as possible.

Puncture

Sensor(s) not detected or faulty
A message appears in the screen, ac-
companied by an audible signal, to
identify the wheel or wheels which are
not detected or to indicate a malfunc-
tion in the system.
Contact a CITROËN dealer or a quali-
fi ed workshop to replace the faulty
sensor(s).
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired)
or when one or more wheels
without a sensor are fi tted.
If your vehicle is equipped with
a spare wheel, this is not fi tted
with a sensor. All repairs and changing of tyres
on a wheel fi tted with this sys-
tem must be carried out by a
CITROËN dealer or a qualifi ed
workshop.
If, when changing a tyre, you
install a wheel which is not de-
tected by your vehicle (example:
fi tting of snow tyres), you must
have the system reinitialised by
a CITROËN dealer or a qualifi ed
workshop.
The tyre under-infl ation detec-
tion system is an aid to driving
which does not replace the need
for the driver to be vigilant or to
drive responsibly. This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the ve-
hicle is maintained and prevent
premature wear of the tyres, par-
ticularly in arduous driving condi-
tions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detec-
tion system may experience
temporary interference due to
electro-magnetic emissions on a
frequency close to that used by
the system.


)
Check the tyre pressures as soon
as possible.
This check must be carried out when
the tyres are cold.

LANE DEPARTURE WARNING
SYSTEM
The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver.

Activation



)
Press this button, the indicator lamp
comes on.



Deactivation



)
Press this button again, the indicator
lamp goes off.
The status of the system remains in the
memory when the ignition is switched
off.


Detection

You are warned by the vibration of the
driver's seat cushion:


- on the right-hand side, if the mark-
ing on the ground has been crossed
on the right,

- on the left-hand side, if the marking
on the ground has been crossed on
the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the di-
rection indicator is switched off.
A warning may be transmitted if a direc-
tion marking (e.g. arrow) or non-standard
marking (e.g. graffi ti) is crossed.


Operating fault


The detection may be impeded:


- if the sensors are dirty (mud,
snow...),

- if the markings on the ground
are worn,

- if there is little contrast be-
tween the markings on the
ground and the road surface.

System which detects the involuntary
crossing of longitudinal traffi c lane mark-
ings on the ground (solid or broken
line).
Sensors, fi tted below the front bumper,
trigger a warning if the vehicle drifts
over a lane marking (speed higher than
50 mph (80 km/h)).
This system is particularly useful on
motorways and main roads. In the event of a malfunction,
the service warning lamp
comes on, accompanied by
an audible signal and a message in the
screen.
Contact a CITROËN dealer or a qualifi ed
workshop.

BLIND SPOT SENSORS


This driving assistance system warns
the driver of the presence of another
vehicle in the blind spot angle of their
vehicle (areas masked from the driver's
fi eld of vision), as soon as this presents
a potential danger.

Operation




)
On switching on the ignition, or en-
gine running, press this button to
activate the function; the warning
lamp comes on.

This system is designed to im-
prove safety when driving and is
in no circumstances a substitute
for the use of the interior rear
view mirror and door mirrors. It
is the driver's responsibility to
constantly check the traffi c, to
asses the distances and relative
speeds of other vehicles and
to predict their movements be-
fore deciding whether to change
lane.
The blind spot sensor system
can never replace the vigilance
and responsibility of the driver.
Sensors fi tted in the front and rear bum-
pers monitor the blind spots. A warning lamp appears in the door
mirror on the side in question:


- immediately, when being overtaken,

- after a delay of about one second,
when overtaking a vehicle slowly.

The system may suffer tem-
porary interference in certain
weather conditions (rain, hail...).
In particular, driving on a wet sur-
face or moving from a dry area to
a wet area can cause false alerts
(for example, the presence of a
fog of water droplets in the blind
spot angle is interpreted as a ve-
hicle).
In bad or wintry weather, ensure
that the sensors are not covered
by mud, ice or snow.
Take care not to cover the warn-
ing zone in the door mirrors or
the detection zones on the front
and rear bumpers with adhesive
labels or other objects; they may
hamper the correct operation of
the system.



)
To deactivate the system, press this
button again; the warning lamp goes
off.
The state of the system remains in
memory on switching off the ignition.

Operating fault

In the event of a fault, the warning lamp
in the button fl ashes then goes off.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
The system is automatically de-
activated when towing with a
towbar approved by CITROËN.
