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.
Avoid using the SPORT mode for too long, in
order to limit your fuel consumption.
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).

A few definitions…
Range
(miles or km)The distance which can still be travelled with the fuel remaining in the tank (related
to the average fuel consumption over the last
few miles (kilometres) travelled).
This value may fluctuate if a change of driving style or terrain results in a
significant change in the current fuel
consumption.
Dashes are displayed when the range falls below
20 miles (30km).
After filling with at least 5 litres of fuel, the range
is recalculated and is displayed if it exceeds 60
miles (100 km).
If dashes instead of figures continue to
be displayed when driving, contact a
CITROËN dealer or a qualified workshop.
Current fuel consumption
(mpg or km/l or l/100 km)Calculated over the last few seconds.
This function is only displayed from 19 mph (30 km/h).
Average fuel consumption
(mpg or km/l or l/100 km)Calculated since the last trip computer
reset.
Average speed
(mph or km/h)Calculated since the last trip computer
reset.
Distance travelled
(miles or km)Calculated since the last trip computer
reset.
Time counter in Stop & Start
(minutes / seconds or hours / minutes)
A time counter calculates the time spent in STOP
mode during a journey.
It resets to zero every time the ignition is
switched on.

Steering wheel
adjustment


► When stationary, lower the control A to
release the steering wheel.
► Adjust the steering wheel height and reach to
suit your driving position.
► Raise the control A to lock the steering
wheel.
As a safety precaution, these operations should only be carried out while the
vehicle is stationary.
► Turn the knob manually to obtain the desired
level of lumbar support.
Head restraint height
adjustment


► To raise it, pull it upwards as far as possible
(notch).
►

T
o remove it, press the lug A and pull it
upwards.
►

T
o put it back in place, engage the head
restraint rods in the openings keeping them in
line with the seat backrest.
►

T
o lower it, press the lug A and push down on
the head restraint at the same time.
The head restraint has a frame with notches which prevents it from lowering;
this is a safety device in case of impact.
The adjustment is correct when the upper
edge of the head restraint is level with the
top of the head.
Never drive with the head restraints removed;
they must be fitted and correctly adjusted.
Heated seats


► With the engine running, use the adjustment
knob to switch on and select the level of heating
required:
0


: Off.
1


: Low.
2


: Medium.
3


: High.
The front seats can be heated individually.
Before leaving the vehicle, ensure that
the adjustment knob of the passenger
seat is at position
0, so that the heating does
not unnecessarily operate if no passenger is
present during the next journey.
Do not use the function when the seat
is not occupied.
Reduce the heating intensity as soon as
possible.
When the seat and passenger compartment
have reached a satisfactory temperature,
switch the function off; reducing electricity
consumption in turn decreases fuel
consumption.
Prolonged use of the heated seats is not
recommended for those with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (illness, taking
medication, etc.).
To keep the heated pad intact and to prevent
a short circuit:
–

do not place sharp or heavy objects on the
seat,
–


do not kneel or stand on the seat,
–


do not spill liquids onto the seat,
–


never use the heating function if the seat
is wet.

Driving
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (request for power, acceleration,
braking, etc.).
The system never suggests:
– engaging first gear.
– engaging a lower gear.
– engaging reverse.
With a manual gearbox, the arrow may
be accompanied by the recommended
gear. The system always suggests changing
to a higher gear when this is necessary.
Hill start assist
This system keeps your vehicle briefly stationary
(for approximately 2 seconds) when making a hill
start, while you transfer your foot from the brake
pedal to the accelerator pedal.
This system is only active when:
– the vehicle is completely stationary, with your
foot on the brake pedal,
– certain slope conditions are met,
– the driver’s door is closed.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If someone needs to get out of the vehicle
with the engine running, apply the parking
brake manually. After that, ensure that the
parking brake indicator lamp and the indicator
Manual operation
To limit fuel consumption during an extended standstill with the engine
running (for example, in a traffic jam), set the
gear selector to N and apply the parking
brake.
►

Selecting position

M
enables sequential
shifting between the six gears.
►

Push backwards to shift up a gear
.
►

Push forwards to shift down a gear
.
The gearbox only changes gear if the road
speed and engine speed permit; apart from
this condition, the rules for automatic operation
temporarily apply.
D disappears, and the gears engaged appear in
succession on the instrument panel.
If the engine speed is too low or too high, the
selected gear flashes for a few seconds, then the
gearactually activated is displayed.
It is possible to change from position D to
position M
at any time.
When the vehicle is stationary or moving
very slowly, the gearbox selects gear M1
automatically.
The Sport programme is inactive in manual
operation.
This symbol is displayed if a gear is not engaged correctly (gear selector between
two positions).
Switching off the vehicle
Before switching off the engine, it is possible to
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle.
If the gear selector is not in position P,
when the driver's door is opened or
approximately 45 seconds after the ignition is
switched off, an audible signal sounds and a
message appears.
►

Return the gear selector to P

; the audible
signal stops and the message disappears.
Malfunction
In the event of a malfunction, this warning
lamp comes on and a message is
displayed, when the ignition is switched on.
In this case, the gearbox goes into back-up
mode and is locked in 3
rd gear. You may feel a
significant jolt (without risk for the gearbox) while
changing from

P

to R and from N to R.
Do not exceed 62 mph (100
km/h), local speed
restrictions permitting.
Have the system checked by a CITROËN dealer
or a qualified workshop.
There is a risk of damaging the gearbox: – If the accelerator and brake pedals are
pressed simultaneously
.
–

In the event of a battery failure, forcing the
selector from position P

to another position.
With an automatic gearbox, never try to
start the engine by pushing the vehicle.
Gear efficiency indicator
(Depending on engine.)
This system helps reduce fuel consumption by
recommending the most appropriate gear.
Operation
Depending on the driving situation and the
vehicle's equipment, the system may advise to
skip one or more gears.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
This function cannot be deactivated.
On certain BlueHDi Diesel versions with
manual gearbox, the system may suggest
changing into neutral ( N is displayed in the
instrument panel) so that the engine can go into
standby (STOP mode with Stop & Start), in
certain driving conditions.
The system is only active on vehicles fitted with a manual gearbox.
The information appears in the instrument panel in the form of an arrow.

Driving
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,
queues, etc.). The engine restarts automatically
- START mode - as soon as the driver wishes to
move off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
The function is activated by default when the
ignition is switched on.
It is set via the Driving / Vehicle touch
screen menu.
A message in the instrument panel confirms the
change of status.
When the function is deactivated, if the engine
was in standby, it restarts immediately.
Associated indicator lamp
Function activated.
Opening the bonnet
Before doing anything under the bonnet,
deactivate the Stop & Start system to avoid
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
Under-inflation detection does not
replace the need for vigilance on the part
of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases fuel consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10
km) at
moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.
Snow chains
The system does not have to be
reinitialised after fitting or removing snow
chains.
Spare wheel
The steel spare wheel does not have an
under-inflation detection sensor.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and the display of a message.
►

Reduce speed immediately
, avoid excessive
steering movements and avoid sudden braking.
►

Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not always cause visible bulging of the tyre.
Do not rely on just a visual check.
►

Using a compressor
, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
►

If it is not possible to make this check
immediately

, drive carefully at reduced speed.
►

In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the system is reinitialised.
Reinitialisation
Reinitialise the system after adjusting one or
more tyre pressures and after changing one or
more wheels.


Before reinitialising the system, make
sure that the pressures of the four tyres
are correct for the conditions of use of the
vehicle and conform to the values written on
the tyre pressure label.
Check the pressures of the four tyres before
performing the reinitialisation.
The system does not advise if a pressure is
incorrect at the time of reinitialisation.
With the vehicle stationary, the system is
reinitialised via the Driving /
V
ehicle touch screen menu.
Malfunction
These warning lamps come on in the event of a malfunction.
In this case, the tyre under-inflation monitoring
function is no longer performed.
Have the system checked by a CITROËN dealer
or a qualified workshop.
