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.
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.
Eco-driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
The gear efficiency indicator invites you to engage the most suitable
gear: as soon as the indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted 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 help to reduce the background traffic noise.
I
f your vehicle has cruise control, make use of the system at speeds
above 25 mph (40 km/h) when the traffic is flowing well.

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,
passenger compartment filter...) and observe the schedule of
operations recommended in the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system is faulty your vehicle
becomes polluting; go to a CITROËN dealer or a qualified workshop
without delay to have the emissions of nitrogen oxides brought back to
the legal level.
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.

A few definitions…
Range
(miles or km)
The distance which can still be
travelled with the fuel remaining
in the tank (at the average fuel
consumption seen over the last
few miles (kilometres) travelled).
Current fuel
consumption
(mpg or l/100 km or km/l)
Calculated over the last few seconds.
Average fuel consumption
(mpg or l/100 km or km/l)
Calculated since the last trip
computer reset.
Distance travelled
(miles or km)
Calculated since the last trip
computer reset.
When the range falls below 20 miles (30 km),
dashes are displayed.
After filling with at least 5 litres of fuel, the
range is recalculated and is displayed if it
exceeds 60 miles (100 km).
Stop & Start time
counter
(minutes / seconds or hours /
m inutes)
If your vehicle is fitted with
Stop & Start, a time counter
calculates the time spent in
STOP mode during a journey.
It resets to zero every time the
ignition is switched on with
the
key.
This function is only displayed from
20

mph (30 km/h).
This value may vary following a change
in the style of driving or the relief,
resulting in a significant change in the
current fuel consumption.
If dashes are displayed continuously
while driving in place of the digits,
contact a CITROËN dealer or a
qualified workshop.
Average speed
(mph or km/h)
Calculated since the last trip
computer reset.

Do not use the function if the seat is not
occupied.
Reduce the level of heating as soon as
possible.
Once the seat and passenger
compartment are at a comfortable
temperature, you can switch off the
function; reducing electric current
consumption also reduces fuel
consumption. Prolonged use at the highest setting
is not recommended for those with
sensitive skin.
There is a risk of burns for those that
do not have normal perception of heat
(illness, taking medicines, ...).
There is a risk of overheating the
system if material with insulating
properties is used, such as cushions or
seat covers.

9. Front demisting / defrosting
In certain cases, the "AUTO"
mode may not be sufficient to
demist or defrost the windows
(humidity, several passengers,
i c e).
8. Rear demisting / defrosting
The heated rear screen operates
independently of the air
conditioning system.
F

P

ress control 8 , with the engine running, to
demist the rear screen and the mirrors. The
indicator lamp comes on.
Demisting is switched off automatically to
avoid excessive consumption of current and
depending on the exterior temperature.
It may be stopped by pressing control 8 again
or when the engine is switched off.
In this latter case, the demisting resumes if the
engine is switched on again within one minute. F

P
ress control 9 to clear the windows
quickly. The indicator lamp comes on.
This system controls the temperature, air flow
and intake and distributes the ventilation to the
windscreen and front side windows.
Resuming manual control exits from the
"Demisting" mode. It must be cancelled as
soon as possible to permit renewal of the air in
the passenger compartment and demisting.
Pressing one of the controls 1a or 1b returns
the system to the "AUTO" mode.
With Stop & Start, when demisting has
been activated, the STOP mode is not
available. When starting with the engine cold,
air flow will reach its optimum level
gradually to prevent an excessive
distribution of cold air.
When entering the vehicle after it has
been parked for a fairly long period, if
the interior temperature is very different
from your comfort setting there is
no need to change the temperature
displayed in order to quickly reach the
level of comfort required. The system
automatically uses its maximum
per formance to correct the difference in
temperature as quickly as possible.
The water resulting from the air
conditioning condensation is
discharged via an opening provided
for this purpose; therefore, a puddle of
water may form underneath the vehicle
when stationary.
In all seasons, if the weather is cool,
the air conditioning is useful as it
removes the humidity from the air
and the condensation. Avoid driving
for prolonged periods with the air
conditioning switched off.
Switch off the rear screen and
exterior mirrors demisting when you
consider this necessary, as low current
consumption reduces fuel consumption.

System which reduces fuel consumption by recommending the most appropriate gear.
Depending on the driving situation and your
vehicle's equipment, the system may advise
you to skip one (or more) gear(s). You can
follow this instruction without engaging the
intermediate gears.
The gear engagement recommendations must
not be considered compulsory. Indeed, the
configuration of the road, the amount of traffic
and safety remain determining factors when
choosing the best gear. Therefore, the driver
remains responsible for deciding whether or not
to follow the advice given by the system.
This function cannot be deactivated.Example:
-

Y
ou are in third gear.
-

Y
ou press the accelerator pedal.
Gear shift indicator*
Operation
With an automatic gearbox, the system
is only active in manual mode.
* Depending on engine. The information appears in the instrument
panel in the form of an arrow.
On vehicle fitted with a manual gearbox,
the arrow may be accompanied by the gear
recommended.
The system adapts its gear change
recommendation according to the
driving conditions (slope, load, ...) and
the demands of the driver (power,
acceleration, braking, ...).
The system never suggests:
-
e
ngaging first gear,
-
enga
ging reverse gear,
- c hanging down.
-
T
he system may suggest that you engage
a higher gear.
