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.
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).

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.
For more information on a system or a function,
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.
