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.

Instruments and controls
EMISSIONS CONTROLS
EOBD (European On Board Diagnosis) is
a diagnostics system which complies with,
among others, the standards concerning
authorised emissions of:
- CO (carbon monoxide),
- HC (unburnt hydrocarbons),
- NOx (nitrous oxides) or particles, detected by oxygen sensors placed
upstream and downstream of the
catalytic converters.
TYRE UNDER-INFLATION DETECTION
System which automatically checks the
pressures of the tyres while driving.
The tyre under-inflation detection
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 check the tyre pressures regularly
(including the spare wheel) and before a
long journey.
Driving with under-inflated tyres adversely
affects road holding, extends braking
distances and causes premature tyre
wear, particularly under arduous conditions
(vehicle loaded, high speed, long journey).
Driving with under-inflated tyres
increases fuel consumption.
The system continuously monitors the
pressures of the four tyres, as soon as the
vehicle is moving.
A pressure sensor is located in the valve of
each tyre (except the spare wheel).
The system triggers an alert if a drop in
pressure is detected in one or more tyres. The tyre pressures must be checked
when the tyres cold (vehicle stopped
for 1 hour or after driving for less then
6 miles (10 km) at moderate speed).
Otherwise, add 0.3 bar to the values
indicated on the label.
The tyre pressures for your vehicle can be
found on the tyre pressure label.
The driver is warned of any
malfunction of this emission
control system by the illumination
of this specific warning lamp in
the instrument panel.
There is a risk of damage to the catalytic
converter. Have it checked by a CITROËN
dealer or a qualified workshop.
Refer to the "Technical data -
Identification markings" section.

Gearbox and steering wheel
To change gear easily, always depress the
clutch pedal fully.
To prevent the mat from becoming caught
under the pedal:
- ensure that the mat is positioned correctly,
- never fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear
the internal components of the gearbox
over time.
MANUAL GEARBOX
Reverse gear
Raise the collar under the gear knob to
engage reverse gear. Never engage reverse gear before the
vehicle is completely stationary.
The lever should be moved slowly to reduce
the noise on engaging reverse gear.
Your reversing manoeuvre is indicated by an
audible exterior warning.
If your vehicle is fitted with parking
sensors, the system comes into
operation when reverse gear is engaged and
an audible signal is heard.
Refer to the "Technology on board -
Parking sensors" section.
GEAR EFFICIENCY INDICATOR
This system allows fuel consumption to be
reduced by suggesting when to change up.
The gear engagement recommendations
should not be considered to be compulsory.
This because the configuration of the
road, the traffic density and safety remain
determining factors when choosing the
best gear. Therefore, the driver remains
responsible for deciding whether or not to
follow the advice given by the system.
The system never recommends engaging
first gear or reverse, or changing down.

40
Starting and stopping
The Stop & Start system puts the engine
temporarily into standby - STOP mode -
during stops in the traffic (red lights, traffic
jams, or other...). The engine restarts
automatically - START mode - as soon as
you want to move off. The restart takes
place instantly, quickly and silently.
Perfect for urban use, the Stop & Start
system reduces fuel consumption and
exhaust emissions and offers the comfort
of complete silence when stationary.
STOP & START
Operation
Going into engine STOP mode
With the vehicle stationary, put the gear
lever into neutral, then release the clutch
pedal. - The "S" warning lamp comes on in the instrument
panel and the engine goes
into standby. Automatic stopping of the engine is
only possible after the vehicle has
exceed a speed of about 6 mph (10 km/h),
to avoid repeated stopping of the engine
when driving slowly.
Never leave your vehicle with out first
turning off the ignition with the key.
Never refuel with the engine
in STOP mode; you must switch
off the ignition with the key. Special cases: STOP mode
unavailable
The STOP mode is not invoked when:
- the system is initialising,
- the driver's door is open,
- the driver's seat belt is not fastened,
- the air conditioning is running,
- the heated rear screen is on,
- the windscreen wiper is on fast wipe,
- reverse gear is engaged, for a parking
manoeuvre,
- some special conditions (battery charge, engine temperature, particle
filter regeneration, braking assistance,
ambient temperature...) where the
engine is needed to assure control of
a system.
The "S" warning lamp flashes for
a few seconds, then goes off.
This operation is perfectly normal.
