EXTERIOR


Parking sensors
This system measures the size of a
free parking space between two ve-
hicles or obstacles.



169

Stop & Start system
This system puts the engine temporar-
ily into standby during stops in the traf-
fi c (traffi c lights, traffi c jams, etc...). The
engine restarts automatically as soon
as you want to move off. The Stop &
Start system allows reductions of fuel
consumption and exhaust emissions,
as well as noise levels when stationary.



158

Welcome lighting
This additional exterior and interior light-
ing, controlled remotely, makes your
approach to the vehicle easier when the
light is poor.



101


Directional lighting
This lighting automatically provides
additional visibility when cornering.



103

Cornering lighting
At low speed, this lighting provides
additional visibility when cornering,
at junctions, and when parking...
making use of the corresponding
front foglamp.

Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.


Optimise the use of your
gearbox

With a manual gearbox, move off gen-
tly, change up without waiting and drive
by changing up quite soon. If your vehi-
cle has the system, the gear effi ciency
indicator invites you to change up; it is
displayed in the instrument panel, fol-
low its instructions.

With an automatic or electronic gear-
box, stay in Drive "D"
or Auto "A"
, ac-
cording to the type of gearbox, without
pressing the accelerator pedal heavily
or suddenly.



Drive smoothly


Maintain a safe distance between ve-
hicles, use engine braking rather than
the brake pedal, and press the accel-
erator progressively. These practices
contribute towards a reduction in fuel
consumption and CO
2 emissions and
also helps reduce the background traf-
fi c noise.

If your vehicle has cruise control, make
use of the system at speeds above
25 mph (40 km/h) when the traffi c is
fl owing 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
(sun roof and window blinds...).
Switch off the air conditioning, unless
it has automatic digital regulation, as
soon as the desired temperature is at-
tained.
Switch off the demisting and defrost-
ing controls, if not automatic.
Switch off the heated seat as soon as
possible.













































ECO-DRIVING

27

Switch off the headlamps and front
foglamps when the level of light does
not require their use.

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 (fi lm, music,
video game...), you will contribute
towards limiting the consumption of
electrical energy, and so of fuel.
Disconnect your portable devices be-
fore leaving the vehicle.



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 refi t 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 fi lter, air fi lter...) and
observe the schedule of operations
recommended by the manufacturer.



When refuelling, do not continue after
the 3 rd cut-off of the nozzle to avoid
any overfl ow.

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.

Display confi guration
This menu is used to confi gure:


- the display language of the central
screen, from a pre-defi ned list,

- the units: temperature (°Celsius or
°Fahrenheit) and fuel consumption
(l/100 km, mpg or km/l),

- the graphical presentation of the cen-
tral screen, from a pre-defi ned list.


Choice of sounds
This menu allows you to choose a family of
polyphonic sounds from the four available.
These sounds are grouped together in a
family and are adapted to suit the situation
and context (alert, confi rmation, rejection,
direction indicators, lighting left on, key in
ignition...).

A few definitions…

This value may vary following a
change in the style of driving or
the relief, resulting in a signifi -
cant change in the current fuel
consumption.
If dashes are displayed continu-
ously while driving in place of the
digits, contact a CITROËN dealer
or a qualifi ed workshop. This function is only displayed
from 20 mph (30 km/h).
Range
(miles or km)
This indicates the distance
which can still be travelled
with the fuel remaining in the tank in
relation to the average fuel consump-
tion over the last few miles (kilometres)
travelled.
When the range falls below 20 miles
(30 km), dashes are displayed. After
fi lling with at least 5 litres of fuel, the
range is recalculated and is displayed
when it exceeds 60 miles (100 km).
Current fuel consumption
(mpg or l/100 km or km/l)
This is the average fuel con-
sumption during the last few
seconds.

Average fuel consumption
(mpg or l/100 km or km/l)


This is the average fuel con-
sumption since the last trip
computer zero reset.
Average speed
(mph or km/h)
This is the average speed calcu-
lated since the last trip computer
zero reset (ignition on).

Distance travelled
(miles or km)
This indicates the distance
travelled since the last trip
computer zero reset.








Stop & Start time counter
(minutes/seconds or hours/
minutes)
If your vehicle is fi tted with Stop & Start,
a time counter calculates the time spent
in STOP mode during a journey.
It resets to zero every time the ignition
is switched on with the key.

The fuel consumption of your ve-
hicle will be higher than the offi cial
fi gures obtained by CITROËN dur-
ing the fi rst 3 000 miles (5 000 km)
of the vehicle's life.
