Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise their
fuel consumption and CO
2emissions.
Optimise your use of the gearbox
With a manual gearbox, move off gently and
change up promptly. While accelerating, change
up early.
With an automatic gearbox, favour automatic
mode and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency indicator prompts you to
engage the most suitable gear: whenever this
indication is displayed on the instrument panel,
follow it straight away.
With an automatic gearbox, this indicator
appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles, use
engine braking rather than the brake pedal and
press the accelerator gradually. These attitudes
help to save fuel, reduce CO
2 emissions and
decrease general traffic noise.
If the vehicle has the steering-mounted
"CRUISE" control, use cruise control at speeds
above 25 mph (40

km/h) when the traffic is
flowing well.
Use electrical equipment wisely
Before moving off, if the passenger compartment
is too warm, ventilate it by opening the windows
and air vents before using the air conditioning.
At speeds above 31
mph (50 km/h), close the
windows and leave the air vents open.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (sunroof blind and window blinds, etc.).
Unless automatically regulated, switch off the air
conditioning as soon as the desired temperature
has been reached.
Switch off the demisting and defrosting functions,
if they are not managed automatically.
Switch off the heated seat as soon as possible.
Switch off the headlamps and foglamps when
the visibility conditions do 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, avoid connecting your
multimedia devices (film, music, video game,
etc.) to help reduce consumption of electrical
energy, and hence fuel.
Disconnect all portable devices before leaving
the vehicle.
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the
heaviest items in the boot, as close as possible
to the rear seats.
Limit the loads carried in the vehicle and
minimise wind resistance (roof bars, roof rack, bicycle carrier, trailer, etc.). Preferably, use a
roof box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and refit
summer tyres.
Avoid using the SPORT mode for too long, in
order to limit your fuel consumption.
Comply with servicing instructions
Check tyre pressures regularly, with the tyres
cold, referring to the label in the door aperture on
the 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.
Do not overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter

, air filter, passenger compartment filter,
etc.) and observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
is faulty, your vehicle will emit pollution. Visit
a CITROËN dealer or a qualified workshop
as soon as possible to restore your vehicle’s
nitrogen oxide emissions to regulatory
compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, to avoid overflow.
You will only see the fuel consumption of your
new vehicle settle down to a consistent average
after the first 1,900 miles (3,000 kilometres).

Resetting the service indicator

After each service, the service indicator must be
reset to zero.
If you have carried out the service on your
vehicle yourself:
►

switch off the ignition,
►


press and hold the button on the end of the
lighting control stalk,
►


switch on the ignition; the distance recorder
display begins a countdown,
►


when the display indicates " =0

", release the
button; the spanner disappears.
Following this operation, if you wish to
disconnect the battery, lock the vehicle
and wait at least five minutes for the zero
reset to be taken into account.
Retrieving the servicing information
You can view the servicing information by
pressing the “ Diagnostic
" button in the
Driving / Vehicle touch screen menu.
Engine oil level indicator
(depending on version)
On versions fitted with an electric oil level
indicator, the state of the engine oil level is
displayed in the instrument panel for a few
seconds, after the servicing information.
The level read will only be correct if the vehicle is on level ground and the engine
has been off for more than 30 minutes.
Oil level correct

AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot
function without AdBlue
®fluid.
When the level of AdBlue® falls below the
reserve level (between 1,500 miles and 0 miles
(2,400 and 0

km)), a warning lamp lights up
when the ignition is switched on and an estimate
of the distance that can be travelled before
engine starting is prevented is displayed in the
instrument panel.
The engine starting prevention system required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the
engine until the minimum level of AdBlue
® has
been topped up.
Manual display of the range
While the driving range is greater than
1,500 miles (2,400 km), it is not displayed
automatically.
You can view the range information by pressing the " Diagnostic" button
in the
touch screen’s Driving
/ Vehicle menu.
Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reserve
level corresponding to a range of 1,500 miles
(2,400
km).
Together with the warning lamps, messages
regularly remind you of the need to top up to
avoid engine starting being prevented. Refer to
the Warning and indicator lamps section for
details of the messages displayed.

If a malfunction is detected,
these warning lamps come on,
accompanied by an audible
signal and an "Emissions fault”
message.
The alert is triggered while driving, when the
fault is detected for the first time, and thereafter
when switching on the ignition for subsequent
journeys, while the cause of the fault persists.
If the fault is temporary, the alert
disappears during the next journey, after
self-diagnostic checks of the SCR emissions
control system.

If the fault indication is still displayed
permanently after 31 miles (50 km) of driving, the
fault in the SCR system is confirmed.
The AdBlue warning lamp flashes, and an
"Emissions fault: Starting prevented in X
miles" or "NO START IN X miles" message is
displayed, indicating the driving range in miles or
kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching
on the ignition.
You can continue driving for up to 685 miles
(1,100
km) before the engine immobiliser
system is triggered.
Have the system checked by a
CITROËN dealer or a qualified workshop
as soon as possible.
Starting prevented
Whenever the ignition is switched on, the
"Emissions fault: Starting prevented" or "NO
START IN" message is displayed.
To be able to restart the engine, contact a CITROËN dealer or a qualified
workshop.
Touch screen
The touch screen gives access to:
– the heating / air conditioning controls,
–

menus for adjusting settings for vehicle
functions and systems,
–


audio system and telephone controls and the
display of associated information,
and, depending on equipment, allows:
–


the display of alert messages and the visual
parking sensors information,
–


the permanent display of the time and the
exterior temperature (a blue warning lamp
appears when there is a risk of ice),
–


access to the internet services and navigation
system controls and the display of associated

As a safety measure, the driver must
only carry out operations that require
sustained attention with the vehicle
stationary.
Some functions are not accessible when
driving.
