Eco- driving
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.
Adopt a smooth driving style
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 31 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, etc.).
Switch off the air conditioning, unless it has
automatic regulation, as soon as the desired
temperature is attained. Switch off the lamps 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 when not required, if they are not
automatically controlled.
Switch off the heated seat 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 electronic or
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.
Do not forget the spare wheel and the tyres on
any trailer or caravan. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter, etc.) and
obser ve the schedule of operations 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
bring your vehicle's nitrogen oxides emissions
back in line with the regulations.
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 the first 1,900 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 (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 19 miles (30 km).
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 l/100 km or km/l) Calculated during the last few
seconds.
This function is only displayed at speeds
above 19 mph (30 km/h).
Average fuel consumption
(mpg or l/100 km or km/l) 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.
Stop & Star t time counter
(minutes/seconds or hours/minutes)
A cumulative time counter for periods in STOP
mode during a journey.
It resets to zero every time the ignition is
switched on.
Distance recorders
The total and trip distances are displayed for
thirty seconds when the ignition is switched off,
when the driver's door is opened and when the
vehicle is locked or unlocked.

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

M
ove the selector towards the - sign to
change down a gear.
It is only possible to change from one gear to
another if the vehicle speed and engine speed
permit; otherwise, the gearbox will operate
temporarily in automatic mode.
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 actual gear engaged is displayed.
It is possible to change from position D
(automatic) to position M (manual) at any time.
When the vehicle is stationary or moving
very slowly, the gearbox engages first gear
automatically.
The sport programme is inactive in manual
operation.
Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle.
If the selector is not in position P , when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, a warning message appears in the
screen.
F

R
eturn the selector to position P ; the
message disappears.
When driving on flooded roads or when
crossing a ford, proceed at walking pace.
Malfunction
When the ignition is on, the lighting
of this warning lamp, associated
with an audible signal and an alert
message on 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 jolt when changing from P to R and
from N to R. This will not cause any damage to
the gearbox. 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.
Do not exceed 62 mph (100 km/h), local speed
restrictions permitting.
Contact a CITROËN dealer or a qualified
workshop as soon as possible.
Electronic gearbox
(ETG 6)
Six-speed electronic gearbox offering
automatic gear control, without driver
intervention.
You can temporarily take control of gear
changes at any time, using the steering
mounted control paddles.

There is an audible signal upon
engagement of reverse.
If reverse gear is requested when moving, the
warning lamp N flashes and the gearbox goes
into neutral automatically.
To engage reverse, stop the vehicle then, with
your foot on the brake pedal, press control N ,
then R .
Stopping the vehicle
Before switching off the engine, you can:
-
p ress control N to be in neutral,
or
-

l
eave the vehicle in gear; in this case the
vehicle cannot be moved.
For all parking situations, you must apply
the parking brake to immobilise the
vehicle.
When immobilising the vehicle with the
engine running, you must select neutral N .Before doing anything under the bonnet,
ensure that control N has been pressed
and that the parking brake is applied.
Operating fault
With the ignition on, illumination of
this warning lamp, accompanied by
an audible signal and a message,
indicates a gearbox fault.
Have it checked by a CITROËN dealer or a
qualified workshop.
Gear efficiency indicator
This system helps reduce 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. The system is only active on vehicles fitted
with a manual gearbox.
On certain 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 with Stop & Start). In this case, N is
displayed in the instrument panel.
Example:
-
Y
ou are in third gear.
-
Y
ou press the accelerator pedal.
-
T
he system may suggest that you engage a
higher gear.
Gear efficiency recommendations are for
information only. 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 disabled.
The information appears in the instrument
panel in the form of an arrow.
