Eco- driving
Optimise the use of your
gearbox
With a manual gearbox, move off gently
and change up without waiting. When
accelerating, change up early.
With an automatic gearbox, favour automatic
mode and avoid pressing the accelerator
pedal heavily or suddenly.
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.
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.
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.
Consider using equipment that can help keep
the temperature in the passenger compartment
down (sunroof and window blinds, etc.).
Unless it has automatic regulation, switch off
the air conditioning as soon as the desired
temperature has been reached.
Switch off the headlamps and foglamps when
the ambient light level does not require their
use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
Switch off the demisting and defrosting controls,
if not automatic.
Switch off the heated seat control as soon as
possible.
As a passenger, if you avoid connecting your
multimedia devices (film, music, video game,
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
leaving the vehicle.
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 automatic gearbox,
this indicator appears only in manual mode. Eco-driving is a range of everyday practices
that allow the motorist to optimise their fuel
consumption and CO
2 emissions.

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, etc.). Preferably, use a
roof box.
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. Have your vehicle ser viced regularly
(engine oil, oil filter, air filter, passenger
compartment filter, etc.) and obser ve 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. Visit a CITROËN dealer or a
qualified workshop as soon as possible to
make your vehicle’s level of nitrogen oxide
emissions compliant to the standard.
When refuelling, do not continue after the 3
rd
cut-off of the nozzle, to avoid any over flow.
At the wheel of your new vehicle, it is only
after approximately the first 1,850 miles
(3,000
kilometres) that you will see the fuel
consumption settle down to a consistent average.
Do not forget the spare wheel and the tyres on
any trailer or caravan.

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. 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.

F With the engine running, use the adjustment knob to switch on and choose the heating
level desired:
0 : Of f.
1 : Low.
2 : Medium.
3 : High.
The front seats can be heated individually.
Do not use the function when the seat is
not occupied.
Reduce the intensity of the heating as
soon as possible.
When the seat and passenger
compartment have reached an
adequate temperature, you can stop
the function; reducing the consumption
of electrical current reduces fuel
consumption. Prolonged use at the highest setting 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.).
There is a risk of overheating the system if
material with insulating properties is used,
such as cushions or seat covers.
Do not use the system:
-

i
f wearing damp clothing,
-

i
f child seats are fitted.
To avoid breaking the heating element in
the seat:

Malfunction
When the ignition is on, the lighting
of this warning lamp, accompanied
by an audible signal and a message
in the screen, indicates a gearbox
fault.
In this case, the gearbox switches to back-up
mode and is locked in 3
rd gear. You may feel
a substantial knock when changing from P
to R and from N to R. This will not cause any
damage to the gearbox.
Do not exceed 60

mph (100 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
There is a risk of damage to the gearbox:
-

i

f you press the accelerator and brake
pedals at the same time,
-

i

f you force the movement of the
selector from position P to another
position when the battery is flat.
To reduce fuel consumption when at
a prolonged standstill with the engine
running (traffic jam, etc.), put the
selector in position N and apply the
parking brake. If your vehicle has an automatic gearbox,
never try to start the engine by pushing
the vehicle.
Gear efficiency indicator
System which reduces fuel consumption by
recommending the most appropriate gear.
Operation
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.
Gear shift recommendations should not be
considered obligatory. The configuration of the
road, the amount of traffic and safety remain
determining factors when choosing the best
gear. The driver thus remains responsible
for deciding whether to follow or ignore the
system's instructions.
This function cannot be deactivated.
With an automatic gearbox, the system is
only active in manual mode. On BlueHDi Diesel versions with manual
gearbox, in certain driving conditions the
system may suggest changing into neutral so
that the engine can go into standby (STOP
mode of Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-

Y
ou are in 3
rd g e a r.
-
Y
ou press the accelerator pedal.
-

T

he system may suggest that you engage a
higher gear.
The system adapts its gear change
recommendations according to the
driving conditions (slope, load, etc.)
and the demands of the driver (power,
acceleration, braking, etc.).
The system never suggests:
-
e

ngaging first gear,
-
enga

ging reverse gear,
-
enga

ging a lower gear.
The information appears in the instrument
panel in the form of an arrow.
Driving

129
On vehicles fitted with a manual gearbox,
the arrow may be accompanied by the
gear recommended.
Hill start assist
System which keeps your vehicle immobilised
temporarily (approximately 2 seconds) when
starting on a gradient, the time it takes to
move your foot from the brake pedal to the
accelerator pedal.
It is only active when:
-

t
he vehicle is completely stationary, with
your foot on the brake pedal,
-

c
ertain slope conditions are met,
-

t
he driver’s door is closed.Do not leave the vehicle while it is being
held temporarily in the hill start assist
phase.
If you need to leave the vehicle with the
engine running, apply the parking brake
manually then ensure that the parking
brake warning lamp lights up fixed on the
instrument panel. The hill start assist function cannot be
deactivated. However, use of the parking
brake to immobilise the vehicle interrupts
its operation.
On an ascending slope, with the vehicle
stationar y, the vehicle is held for a shor t
time when you release the brake pedal:
With a manual gearbox, if you are in first gear
or in neutral.
With an automatic gearbox, if you are in
position D or M . On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held for a shor t time when you
release the brake pedal.
Malfunction
If a fault in the system occurs, this warning
lamp comes on accompanied by a message.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Stop & Start
The Stop & Start system puts the engine
t emporarily into standby – STOP mode – during
stops in traffic (red lights, traffic jams, etc.). The
engine restarts automatically – START mode –
as soon as you want to move off.
The restart takes place instantly, quickly and
silently.
Per fect for urban use, the Stop & Start system
reduces fuel consumption and exhaust
emissions as well as the noise level when
stationary.
