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.
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.
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 19 mph (30 km/h) when traffic is flowing
smoothly.
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.
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.
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.
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).

For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Warning and indicator
lamps
Displayed as symbols, the warning and indicator
lamps inform the driver of the occurrence of a
malfunction (warning lamps) or of the operating
status of a system (operation or deactivation
indicator lamps). Certain lamps light up in two
ways (fixed or flashing) and/or in several colours.
Associated warnings
The illumination of a lamp may be accompanied
by an audible signal and/or a message displayed
in a screen.
Relating the type of alert to the operating status
of the vehicle allows you to determine whether
the situation is normal or whether a fault has
occurred: refer to the description of each lamp
for further information.
When the ignition is switched on
Certain red or orange warning lamps come on
for a few seconds when the ignition is switched
on. These warning lamps should go off as soon
as the engine is started.

refer to the corresponding section.
Warning lamp continuously
lit
The illumination of a red or orange warning lamp
indicates the occurrence of a fault that needs
further investigation.
If a warning lamp remains lit
The references (1), (2) and (3) in the warning
and indicator lamp description indicate whether
you should contact a qualified professional in
addition to the immediate recommended actions.
(1): You must stop the vehicle .
Stop as soon as it is safe to do so and switch off
the ignition.
(2): Contact a CITROËN dealer or a qualified
workshop.
(3): Visit a CITROËN dealer or a qualified
workshop.

Indicators
Service information
For a few seconds after the ignition is switched
on, the spanner symbolising service information
comes on: the screen informs you when the next
service is due, in accordance with the servicing
schedule indicated in the manufacturer's service
schedule.


This information is determined in relation to the
distance travelled since the previous service.
Engine oil level
Depending on the engine, the engine oil level is
then displayed, on a scale of 1 (Min) to 5 (Max).
If no scale is displayed, the oil level is
insufficient; it is essential to top it up to prevent
engine damage.
For the measurement of this level to be valid, the
vehicle must be parked on horizontal ground,
with the engine having been off for more than 30
minutes.
If in doubt, check the oil level using the
dipstick.
For more information on Checking levels,
refer to the corresponding section.


After a few seconds, the display returns to its
standard functions.
Engine oil quality
This warning lamp flashes and, if your vehicle is equipped with this function, a
message is displayed at each start: the system
has detected a deterioration of the engine oil. It
is essential to change the oil as soon as
possible.
This 2nd warning lamp, coupled with the
1st, lights up on the instrument panel if the
oil change has not been carried out, and the
degradation of the oil has exceeded a new
threshold. If this warning lamp comes on at
