fuel consumption Citroen C4 AIRCROSS RHD 2014.5 1.G Owner's Manual

Eco-drivingEco-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 gently and change up without waiting.
During acceleration change up early.
With an automatic or electronic gearbox, give preference to automatic
mode and avoid pressing the accelerator pedal heavily or suddenly.
The gear shift indicator invites you to change up: as soon as the
indication to change up is displayed in the instrument panel, follow it
straight away.
With an electronic or 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 progressively. These
practices contribute towards a reduction in fuel consumption and
Co
2 emissions and also helps reduce the background traffic noise.
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 (sunroof and window
blinds...).
Switch off the air conditioning, unless it has automatic regulation, as
soon as the desired temperature is attained.
Switch off the demisting and defrosting controls, if not automatic.
Switch off the heated seat as soon as possible.
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
(film, music, video game...), you will contribute towards limiting the
consumption of electrical energy, and so of fuel.
Disconnect your portable devices before leaving the vehicle.
If your vehicle has cruise control, make use of the system at speeds
above 25 mph (40 km/h) when the traffic is flowing well.
Eco-driving

11
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 refit 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:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter 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 filter, air filter...) and
observe the schedule of operations recommended by the manufacturer.
When refuelling, do not continue after the third cut-off of the nozzle to
avoid any over flow.
At the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a consistent average.

Monitoring

When the engine is
running, this indicates the
temperature of the coolant.
Range
When the engine is
running, this indicates
the distance which can
still be travelled with the
fuel remaining in the tank
based on the average
fuel consumption over the
last few miles/kilometres
travelled. This value may vary following a change
in the style of driving or the relief,
resulting in a large variation in the
current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,
you must fill the tank whenever
possible.
Coolant temperature
gauge
If the bar is close to the critical
position located
on the right, the temperature is too high.
The symbol flashes when your engine is
overheating.
You must stop your vehicle as soon as it is
safe to do so.
Wait a few minutes before switching off the
engine. When the range is less than 30 miles (50 km)
,
dashes are displayed.
Refuel as soon as possible. The display of the
range is updated.
Wait for the engine to cool before
topping up the level. The cooling system
is pressurised.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the
pressure to drop.
When the pressure has dropped,
remove the cap and top up the level,
if
necessary.
Contact a CITROËN dealer or a
qualified workshop. When you disconnect the battery,
the previous fuel consumption data
is lost and the value displayed will be
different from that displayed before the
battery was disconnected. The distance
displayed must be considered an
approximate indication.

Average fuel consumption
(l/100 km or km/l or mpg)
This is the average fuel
consumption calculated
since the trip computer was
last reset.
Average speed
(km/h or mph)
This is the average speed
calculated since the trip
computer was last reset.
Current fuel consumption
(l/100 km or km/l or mpg)
This is the average fuel
consumption calculated over
the last few seconds.
This value may change following a
change in the style of driving or the relief.
If dashes "- - -" are displayed for long
periods in place of the digits while
driving, contact a CITROËN dealer or a
qualified workshop.
Resetting the information to zero
When the required information is displayed,
press the INFO button for more than
two
seconds to reset all of the information to
zero.
When the ignition is switched on, the zero reset
switches automatically from manual mode to
automatic mode.
Automatic
If the ignition key remains in the OFF position
for more than 4 hours, the information is reset
to zero automatically.
