Motoring & Environment
ENVIRONMENT
With you, CITROËN acts to protect the
environment.
We invite you to visit the
www.citroen.co.uk website. As the driver, you also can contribute to
protecting the environment by following
certain rules:
- adopt a preventive style of driving,
without frequent and harsh acceleration,
- observe the service intervals; we recommend that services are carried
out by a CITROËN dealer, authorised to
collect used batteries and fluids,
- in order to preserve the reliability of the engine and emission control systems, do
not use engine oil additives. Refer to information on eco-driving at
the end of this section.

ECO-DRIVING
Optimise the use of your gearbox
With a manual gearbox, move off gently and change up without
waiting. While accelerating changing up early. If your vehicle has
the system, the gear efficiency indicator invites you to engage the
most suitable gear; follow its instructions as soon as it is displayed
in the instrument panel.
Drive smoothly
Maintain a safe distance between vehicles, use engine
braking rather than the brake pedal, and press the accelerator
progressively. These practices contribute towards a reduction in
fuel consumption and CO
2 emissions and also helps reduce the
background traffic noise.
If your vehicle has cruise control, make use of the system at
speeds above 25 mph (40 km/h) when the traffic is flowing well.
Control the use of your electrical equipment
Before moving off, if the passenger compartment is too warm,
ventilate it by opening the windows and air vents before using the
air conditioning.
Above 30 mph (50 km/h), close the windows and leave the air
vents open.
Remember to make use of equipment that can help keep the
temperature in the passenger compartment down (window
blinds...).
Switch off the air conditioning, unless it has automatic digital
regulation, as soon as the desired temperature is attained.
Switch off the demisting and defrosting controls, if not automatic.
Switch off the heated seat as soon as possible.
Switch off the headlamps and front foglamps when the level of
light does not require their use.
Eco-driving is a range of everyday practices that allow the motorist to \
optimise their fuel consumption and CO
2 emissions.
Avoid running the engine before moving off, particularly in winter;
your vehicle will warm up much faster while driving.
As a passenger, if you avoid connecting your multimedia devices
(film, music, video game...), you will contribute towards limiting the\

consumption of electrical energy, and so of fuel.
Disconnect your portable devices before leaving the vehicle.

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
KEY
This locks and unlocks the doors on the
vehicle, opens and closes the fuel filler cap,
as well as starting and stopping the engine.
REMOTE CONTROL BATTERY
Reference: CR 2032/3 volts.
Changing the battery
- Press the button to eject the key.
- Turn the screw 1 from the closed
padlock to the open padlock using a
screwdriver with a thin lip.
- Use the screwdriver as a lever to extract the battery holder housing 2 . - Remove the housing and change the
battery 3 observing the polarities.
- Put the battery holder housing 2 back
inside the key and secure it by turning
the screw 1 .
There is a risk of damage if the
replacement battery is not of the
correct type.
Only use batteries which are identical or of
an equivalent type to those recommended
by a CITROËN dealer. Take used batteries
to an authorised collection point.

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.

READY TO GO
Remote control fault
Unlock the doors using the key, the alarm is
triggered.
Switch on the ignition, recognition of the
key's code turns off the alarm. Locking the doors with the key does
not set the alarm.
Deactivation using the remote control
When this button is pressed, the
alarm is deactivated when the
vehicle is unlocked.
Deactivation of the anti-tilt protection *
Press this control to deactivate
the protection (when towing the
vehicle with the alarm on, for
example).
The protection remains active until the doors
are unlocked with the central locking.
ALARM
If your vehicle is fitted with an anti-theft
alarm.
This provides:
- exterior perimeter protection by detectors on the openings (doors,
bonnet) and on the electrical power
supply,
- anti-tilt protection * .
Activation of the alarm
First ensure that all of the doors and bonnet
are closed correctly.
* Depending on engine.
Good practice
To deactivate the siren quickly following
a false alarm:
- switch on the ignition, recognition of the key's code will switch off the alarm,
- press the unlocking button (cab and key) on the remote control.
To avoid setting the alarm, when washing
the vehicle for example, lock the vehicle
using the key.
Unlocking the vehicle using the remote
control deactivates the siren automatically.
The alarm is set by pressing this
padlock, the protection is active
after a few seconds.
While the alarm is monitoring,
any intrusion triggers the siren for
approximately 30 seconds, accompanied by
illumination of the direction indicators.
The alarm then returns to
monitoring mode but the triggering
event is stored and is indicated
by illumination of the electronic
immobiliser warning lamp for about
10 seconds when the ignition is switched on.
The alarm is also triggered following an
electrical supply cut-off, when the supply is
restored.
