AT A GLANCE
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in
the bottom of the boot, as close as possible to the rear seats.
Limit the loads carried in the vehicle and reduce wind resistance
(roof bars, roof rack, bicycle carrier, trailer...). Use a roof box in
preference.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit your summer
tyres.
Observe the recommendations on maintenance
Check the tyre pressures regularly, when cold, referring to the
label in the door aperture, driver's side.
Carry out this check in particular:
- before a long journey,
- at each change of season,
- after a long period out of use.
Don't forget the spare wheel and the tyres on any trailer or
caravan.
Have your vehicle serviced regularly (engine oil, oil filter, air
filter, cabin filter...) and observe the schedule of operations in the
maintenance and warranty guide.
When refuelling, do not continue after the 3
rd cut-off of the nozzle
to avoid any overflow.
At the wheel of your new vehicle, it is only after the fi rst 1 800 miles
(3 000 kilometres) that you will see the fuel consumption settle
down to a consistent average.

Access
ELECTRONIC IMMOBILISER
All of the keys contain an electronic
immobiliser device.
This device locks the engine supply system.
It is activated automatically when the key is
removed from the ignition. Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
However, if none of the doors is opened
within approximately thirty seconds following
unlocking, the doors relock automatically.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms…), may interfere with the
operation of the remote control temporarily.
The remote control does not operate while
the key is in the ignition, even if the ignition
is off, except for reinitialisation.
Good practice
Make a careful note of the number of the
keys. If they are lost, your CITROËN dealer
will be able to carry out his work more
quickly and effectively if you give him this
number and the confidential card.
Do not make any modifications to the
electronic immobiliser system. This warning lamp is switched off
after the ignition is switched on
and the key has been recognised,
the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.
Driving with the doors locked may make
access to the passenger compartment
by the emergency services more diffi cult in an
emergency.
As a safety precaution (with children on board),
remove the key from the ignition when leaving
the vehicle, even for a short time.
After the ignition is switched on, a dialogue
is established between the key and the
electronic immobiliser system.
When purchasing a second-hand vehicle:
- ensure that you are given the confidential card,
- have the keys memorised by a CITROËN dealer to ensure that the keys
in your possession are the only ones
which can start the vehicle.
CONFIDENTIAL CARD
This is given to you on delivery of your
vehicle with the duplicate keys.
It contains the identification code necessary
for any work carried out by a CITROËN
dealer on the electronic immobiliser system.
This code is hidden by a film, which should
be removed only if necessary.
Keep your card in a safe place, never inside
the vehicle.
When undertaking a long trip or journey,
however, it is advisable to take it with you
along with your personal papers.

Access
LOCKING / UNLOCKING FROM INSIDE
Door open warning lamp
If this warning lamp comes on,
check that all of the doors and
the bonnet are closed correctly.
Good practice
If you decide to drive with the doors locked,
be aware that this could make access to the
vehicle by the emergency services more
difficult in an emergency.
Cab and load space
Pressing permits electric central
locking and unlocking, when the
doors are closed.
The doors can still be opened from the
inside. If one of the doors is open or is not
closed correctly, the central locking
does not work. The indicator lamp on the control:

Anti-intrusion security

12 mph (20 km/h).
If none of the doors is opened during the
journey, the locking remains active.
