Eco-driving
Eco-driving
Eco-driving refers to a range of everyday
practices that allow the motorist to optimise
the vehicle's energy consumption (fuel and/or
electricity) and CO
2 emissions.
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. Do not depress the accelerator pedal
heavily or suddenly.
The gear shift 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 practices
help to save on energy consumption, reduce
CO
2 emissions and decrease general traffic
noise.
When the traffic is flowing smoothly, select the
cruise control.
Control the use of 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.
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 (e.g.
sunroof blind, window blinds).
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.
Adapt your use of the headlamps and/or
foglamps to the level of visibility, in accordance
with current legislation in the country in which
you are driving.
Avoid running the engine before moving off,
particularly in winter (other than in severe wintry
conditions: temperature below -23°C). The
vehicle will warm up much faster while driving.
As a passenger, avoid connecting your
multimedia devices (e.g.
film, music, video
game) to help reduce the consumption of energy.
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 (e.g.
roof bars, roof
rack, bicycle carrier, trailer). 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.
Comply with the 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 forget the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (e.g.

engine
oil, oil filter, air filter, passenger compartment
filter, etc.). Observe the schedule of operations in
the manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR system
has a fault, 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 legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, 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).

Distance that 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 driving
style or terrain, leading to a significant change in
current fuel consumption.
When the range falls below 19 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 62
miles (100
km).

when grip is poor.
Return to automatic operation
► At any time, press the selected button ("S" or
"T") again to exit the activated programme and
return to auto-adaptive mode.
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.
►

T

o shift up/down through the gears, push the
control backwards/forwards.
The gearbox only changes gear if the vehicle
speed and engine speed conditions allow;
otherwise, the rules for automatic operation are
temporarily applied.
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
gear actually engaged is shown.
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 and Snow programmes are 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 to the gearbox) when
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
depressed simultaneously
.
–

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

to another position.
Automatic gearbox
Never try to start the engine by pushing
the vehicle.
Gear shift indicator
(Depending on engine)
This system is designed to reduce fuel
consumption by recommending the most suitable
gear.
Operation
Depending on the driving situation and
the vehicle's equipment, the system may
recommend skipping one or more gears.
Gear engagement recommendations are
not to be considered mandatory. Indeed, the
configuration of the road, the traffic density and
safety remain determining factors when choosing
the best gear. Therefore, the driver remains
responsible for deciding whether or not to follow
the system’s advice.
The system cannot be deactivated.
With an automatic gearbox, the system is
only active in manual operation.
The information appears on the instrument panel, in the form of an arrow
and the recommended gear.
The system adapts the gear change instructions according to the driving
conditions (e.g. slope, load) and driving style
(e.g. power demand, acceleration, braking).
The system never suggests:
– engaging first gear;
– engaging reverse gear.
Hill start assist
This system keeps the 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.
The 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. Then check that the parking
brake indicator lamp is on fixed on the
instrument panel.

operation.
Operation

Facing uphill, with the vehicle stationary,
the vehicle is held for a short time when you
release the brake pedal:
–

provided you are in first gear or neutral with a
manual gearbox.
–


provided you are in mode D

or M with an
automatic gearbox.


Facing downhill, with the vehicle stationary
and reverse gear engaged, the vehicle is held
for a short time when you release the brake
pedal.
Malfunction
If the event of a malfunction, this warning
lamp lights up on the instrument panel,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving 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.

Practical information
7Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Brake pads
Brake wear depends on the style of
driving, particularly in the case of vehicles
used in town, over short distances. It may be
necessary to have the condition of the brakes
checked, even between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel
or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50
km/h), add
0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases energy
consumption. Non-compliant tyre
pressures cause tyres to wear prematurely
and have an adverse effect on the vehicle's
road holding - risk of accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. Regularly check the condition of the
tyres (tread and sidewalls) and rims as well as
the presence of the valve caps.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; replace the tyres as soon as
possible.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime. Always mark the direction of rotation on the tyres
that will be stored when fitting winter or summer
tyres. Store them in a cool, dry place and away
from direct exposure to the sun's rays.
Winter or 4-seasons tyres can be
identified by this symbol on their
sidewalls.
AdBlue® (BlueHDi)
To respect the environment and ensure compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles with
a system that combines SCR (Selective Catalytic
Reduction) with a Diesel Particle Filter (DPF) for
the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
water, which are harmless to health and the
environment.
The AdBlue® is contained in a special
tank holding about 17 litres.
Its capacity allows a driving range of
approximately 3,900
miles (6,500 km),
which
may vary considerably depending on your
driving style.
An alert system is triggered once the reserve
level is reached: it is then possible to drive for a
