OPERATION
When you engage reverse gear,
a sound signal confi rms to you
that the system is active. The out-line of your vehicle appears on the
screen. Any obstacles located to
the rear or to the front of the vehi-cle can be detected.
When moving forward at a speed less than approx. 6 mph (10 km/h),
whether in neutral or in gear, the vehi-cle outline appears on the screen as soon as an obstacle is detected
in front of the vehicle. Any obstacles located to the rear or to the front of the
vehicle can be detected.
Remarks:The proximity sensors cannot
detect objects that are
immediatel
y under or over the
bumpers.
A thin object such as a spike,
a bollard or similar, can only be detected at the start of themanœuvre but not when the
vehicle arrives close up to it.
In poor weather or in winter,you need to ensure that the sensors are not covered with
mud or with ice or snow.

LANE DEPARTURE WARNING SYSTEM
This driving assistance device warns you when you unwittingly cross a lane marking (either a continuous or a dotted line on the road surface). It is desi-gned for use on motorways and dual carriageways, operating onlyabove
speeds of approx.50 mph (80 km/h).
ACTIVATION/DEACTIVATION
A press on button 1activates the function, the warning lamp on the button lights up.
A second press on button 1 deactivates the function, the warning lamp on
the button goes out.
When you start the engine, the mode (activated/deactivated) selected when you stopped the engine is retained.
OPERATION
Above a speed of around 50 mph (80 km/h), if you cross a lane marking, you are alerted to this by a vibration within
the cushion of your seat:On the right hand side if you cross a lane marking to the right.
On the left hand side if you cross a lane marking to the left.
The system does not alert you if one of your direction indicators is operating and for approx. 20 seconds after the
direction indicator has stopped.
Remarks
This system is designed to identify traffi c lane markings.
In certain cases it ma
y trigger an alert that is unnecessary, for example if the vehicle passes over a directional arrow
or some unusual road marking.
The system may be affected temporarily by conditions external to the vehicle:Detection of lane markings made diffi cult by:
Markings being worn.Insuffi cient contrast with the general road surface.Sensors being negated by:
Driving in snow or heavy rain.Driving on roads that are covered with mud or water puddles.
In the event of prolonged disturbed operation, contact aCITROÀN dealer or a qualifi ed workshop.pg p

DIESEL PARTICULATE FILTER SYSTEM
In addition to the catalytic converter, this fi lter contributes actively to the preserving of air quality, by collecting thepolluting particles that have not been burnt off. Black exhaust fumes are thus eliminated.
Simultaneous lighting of the SERVICEand depollution system warning lamps indicates an
increased risk of clogging.
Contact a CITROËN dealer or a qualifi ed workshop as soon as possible.
DIESEL ADDITIVE LEVEL
If the additive level is low, it is necessary to top up the additive level.
Contact a CITROËN dealer or a qualifi ed workshop as soon as possible.
CLOGGING OF THE PARTICLE FILTER
Clogging is caused by the particle fi lter starting to be saturated (owing to exceptionally long periodsspent driving in urban conditions: low speeds, traffi c jams, etc.).
In order to re
generate the fi lter you are advised to drive as soon as possible, when traffi c conditions allow, at a speedof 37 mph (60 km/h) or more for at least 5 minutes. If the problem persists, contact a CITROÀN dealer or a qualifi edgyp,,p
workshop.Note: If the vehicle has been running for long periods at very low speeds or at idle, vapour emissions may be seencoming from the exhaust under acceleration. These have no consequences for the running of the vehicle or for the environment.

ANTI-THEFT PROTECTION
When you start the vehicle, doors
and boot closed, the system
automatically locksthe doorsas soon as you reach a speed of
around 6 mph (10 km/h).Note: If a door has been opened, this will lock again automatically whenthe vehicle reaches approx. 6 mph(10 km/h).
Activation/Deactivation of
the anti-intrusion protection
Give a long press on control Afor central locking until you see a mes-sage displayed.ANTI-THEFT
The boot locks automatically as soon as the vehicle reaches a
speed of around6 mph (10 km/h).Note: The opening of a door or use of the control A unlocks the vehicle.
Your vehicle is fi tted with doors that have frameless windows. When you open the doors, immediately youaction the exterior handle, a micro-descent device on the SIDE WINDOWS lowers the glass slightly.
If this device were not working properly, it could result in thewindows breaking:If there should be a battery failure:
Open the doors gently.Do not close the door abruptly as this risks breaking the window, if possible wait until the battery ispowering the vehicle again.If you are intending to work on the battery, open the windows fi rst.In freezing conditions, ice may form to hinder the operation of the micro-descent device. If the actionon the door handle does not move the window down, it is essential fi rst to free the ice.

ACCESS
To make it easier to open the doors,
the windows automatically open bya few millimetres.
Note:This movement occurs immediately you touch an interior door handle.
The window recloses, automati-cally adjusting for a perfect seal.
IMPORTANT
This function has no anti-pinch. Donot leave your hand on the window
when you close the door.
Any interruption of your vehicle'selectrical supply will prevent the
windows from opening and closingcorrectly.
Note: Travelling at high speed,closing of windows may be hin-
dered by the aerodynamic pres-sure. Acoustic comfort may then
be adversely affected.
ELECTRICALLY-CONTROLLED CHILD SAFETY
This deactivates the controls in the rear of the vehicle, both for the rear
windows and for opening the rear doors from the inside.
For Pack Lounge seats, the seat slide adjustments, and those for the front
seats from the rear of the vehicle, are also deactivated.

AUTOMATIC AIR CONDITIONING
AIR CONDITIONING
This system automatically adjusts the temperature, the fl ow of air and the distribution of air inside the cabin,
depending on your desired comfort level.
Provided
you retain automatic mode (by pressing button "AUTO") and all the air vents are open, you will main-
tain an optimum comfort level, also removing humidity
and misting, whatever the ambient climatic conditions.
The temperature inside the cabin cannot be lower than
the temperature outside if the air conditioning is not
operating.
To be e
ffective, the air conditioning should only be used
with the windows closed. If after a lengthy stop in bright sunlight the interior temperature is excessive, air the passenger compartment by opening the windows for a
few moments, then close them again.
To keep the air conditioning compressor well sealed, it
is essential to operate the air conditioning at least once every month.
The air conditioning operates by using power from the engine. This results in a slight increase in fuel con-sumption.
Sensors
The automatic regulation of the air conditioning inside
the cabin makes use of a number of sensors, relieving you of the need to make adjustments, other than the desired cabin temperature.
Take care not to obstruct sensor A.
Air inlet
Check that the exterior grille for the air inlet, at the bot-
tom of the windscreen, is clean and free of dead leaves,snow, etc.
If washing the vehicle with a high pressure jet, avoid
targeting the air inlet zone.
Air circulation
For your comfort we advise you to maintain a proper
distribution of air within the cabin, both at the front andat the rear.
The air vents to the
face have thumbwheels so that you can
adjust the fl ow of air, and grilles to orient the direction.
Th
ere are air vents on the fl oor underneath the frontseats and on the rear control panel, for enhancedheating of the rear seat positions.
Do not obstruct the air outlets located in the boot area.
Dust/pollen fi lter
There is a fi lter for excluding pollen and dust.
This
fi lter has to be changed according to the vehicle
maintenance schedule. See "Maintenance and WarrantyGuide".
