Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
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. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift 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 practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
Favour the use of “Eco” driving mode.
With an EAT8 gearbox, with the gear selector
in mode
D, and except in Sport mode, favour
"free-wheeling" by fully lifting your foot from the
accelerator pedal in order to save fuel. When the traffic is flowing smoothly, select the
cruise control.
Control the use of 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.
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 (e.g.
sunroof blind, window blinds).
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.
Adapt the use of headlamps and/or foglamps
depending on visibility conditions.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
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 (e.g.
roof bars, roof
rack, bicycle carrier, trailer). 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 Sport mode for too long, in order to
limit your energy consumption.
Comply with the 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 forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). 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 legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.

service.
►

Switch the ignition off.



► Press and hold this button.
► Switch on the ignition; the distance recorder
display begins a countdown.
► Release the button when =0 is displayed; the
spanner disappears.
If you have to disconnect the battery
following this operation, lock the vehicle
and wait at least 5 minutes for the reset to be
registered.
Reminder of the servicing information
You can access the servicing information at any
time via the instrument panel.


► Press this button to temporarily display the
servicing information.
The distance indicated (in miles or kilometres) is calculated according to the
distance covered and the time elapsed since
the last service.
The alert may be triggered close to a due

(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

18
Instruments
seconds after switching the ignition on, 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 incorrect
This is indicated by the display of a message
prompting you to top up, accompanied by the
Service warning lamp and an audible signal.
If the low oil level is confirmed by a check using
the dipstick, the level must be topped up to avoid
damage to the engine.
For more information on Checking levels, refer
to the corresponding section.
Oil level indicator fault
This is signalled by the display of the " Oil
level measurement invalid" message in the
instrument panel.
Contact a CITROËN dealer or a qualified
workshop.
In the event of a fault with the electric
indicator, the oil level is no longer
monitored.
If the system is faulty, you must check the
engine oil level using the manual dipstick
located under the bonnet.
For more information on Checking levels,
refer to the corresponding section.
Coolant temperature
indicator


With the engine running:
– In zone A, the temperature is correct.
–

In zone
B, the temperature is too high.
The associated warning lamp and the
STOP
warning lamp light up in red on the
instrument panel, accompanied by the display of
a message and an audible signal.
You must stop the vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully open the bonnet and check the coolant
level.
For more information on Checking
levels, refer to the corresponding
section.
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.
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.




► Press this button to temporarily display the
driving range.

1Actions required related to a lack of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reserve

(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.

Malfunction of the SCR emissions
control system
Malfunction detection


If a malfunction is detected,
these warning lamps come
on, accompanied by an
audible signal and the
display of an "
Emissions
control
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, for as long as 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.
Malfunction confirmed during the
permitted driving phase (between 685
miles and 0
miles (1,100 km and 0 km))
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
a message is displayed (" Emissions
control
fault: starting prevented in X miles
(kms)"), 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 starting
prevention system is triggered.
Have the system checked by a
CITROËN dealer or a qualified workshop
as soon as possible.
