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.
Favour the use of “Eco” driving mode.
With an EAT8 gearbox, with the gear selector
in mode
D, and except in Sport mode, favour
"free-wheeling" by fully lifting your foot from the
accelerator pedal in order to save fuel. 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 the use of headlamps and/or foglamps
depending on visibility conditions.
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.
Avoid using Sport mode for too long, in order to
limit your energy consumption.
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
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 legal levels.
When filling the fuel tank, do not continue after
the third cut-out of the nozzle, to avoid overflow.

Heating and Ventilation
Air intake
The air circulating in the passenger compartment
is filtered and originates either from the
exterior, via the grille located at the base of the
windscreen, or from the inside in air recirculation
mode.
Controls
The controls are accessible in the " Air
conditioning " touch screen menu and are also
grouped together in the control panel on the
centre console.
Air distribution

1. Windscreen demisting/defrosting vents
2. Front side window demisting/defrosting vents
3. Adjustable and closable side air vents
4. Adjustable and closable central air vents
5. Air outlets to the front footwells
6. Air outlets to the rear footwells
7. Adjustable and closable air vents, with blower
(depending on version)
Advice
Using the ventilation and air
conditioning system
►

T

o ensure that air is distributed evenly,
keep the external air intake grilles at the base
of the windscreen, the nozzles, the vents, the
air outlets and the air extractor in the boot
free from obstructions.
►

Do not cover the sunshine sensor located
on the dashboard; this sensor is used to
regulate the automatic air conditioning
system.
►

Operate the air conditioning system for at
least 5 to 10 minutes once or twice a month to
keep it in perfect working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing the maximum load on a steep
gradient in high temperatures, switching off
the air conditioning increases the available
engine power, enhancing the towing capacity.
Avoid driving for too long with the ventilation off or with prolonged operation
of interior air recirculation. Risk of misting and
deterioration of the air quality!
If the interior temperature is very high
after the vehicle has stood for a long
time in the sunshine, air the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
Condensation created by the air
conditioning results in a discharge of
water underneath the vehicle. This is perfectly
normal.

Visibility Programme", refer to the section
"Front Demisting/Defrosting ".
Air conditioning on/off.
The air conditioning is designed to operate
effectively in all seasons, with the windows
closed.
It enables you to:
– lower the temperature in summer,
– increase the effectiveness of the demisting in
winter, above 3°C.
► Press button 8 to activate/deactivate the air
conditioning system.
When the indicator lamp is on, the air
conditioning function is activated.
The air conditioning does not operate when the air flow adjustment is inhibited.
To obtain cool air more quickly, you can
use recirculation of the interior air for a few
moments. Then return to the intake of exterior
air.
Servicing the ventilation and air
conditioning system
►

Ensure that the passenger compartment
filter is in good condition and have the filter
elements replaced regularly

.
We recommend using a composite passenger
compartment filter. Thanks to its special active
additive, this type of filter helps to purify the
air breathed by the occupants and keep the
passenger compartment clean (by reducing
allergic symptoms, unpleasant odours and
greasy deposits).
►

T

o ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the

Driving
6partially recharge the traction battery, without
affecting the charge level indicator.
Progressive Hydraulic
Cushions
This suspension system with progressive hydraulic cushions improves driving comfort by
filtering out the imperfections and demands of
the road surface.
Each shock absorber is equipped with a
hydraulic compression stop (at the base) and a
hydraulic rebound stop (at the top).
Depending on the intensity of the shock to be
absorbed, these stops provide the vehicle with a
greater freedom of movement or gradually slow
down the amount of movement in order to avoid
any sudden jolts at the end of travel.
Unlike conventional suspension which absorbs
the energy but then partially returns some of it,
this active suspension absorbs and dissipates
this energy, without producing any rebound.
Driving modes
The number and type of driving modes available depend on the vehicle’s engine and equipment.
Driving modes are selected using one of the
following controls, depending on version:




1. Pressing the control activates Eco mode. The
indicator lamp comes on.
2. Pressing the control activates Sport mode.
The indicator lamp comes on.
3. Pressing the control displays the modes on
the instrument panel.
The selected mode is activated immediately.
With petrol / Diesel engines
Each time the ignition is switched on, Normal
mode is selected by default.
Eco
Reduces energy consumption by restricting the
performance of the heating and air conditioning
systems, although it does not deactivate them.
Normal
Restores the vehicle’s original settings.
Sport
Enables more dynamic driving with action on the
power steering, accelerator and gear changes
(with an automatic gearbox).
Depending on version, with an EAT8
gearbox and the selector in position D
(except Sport mode), fully releasing the
accelerator pedal allows free-wheeling which
can save fuel.
A drop in engine speed is normal (rev counter
at idle, drop in engine noise).
With rechargeable hybrid
engine
Each time the ignition is switched on, Electric
mode is selected by default.
Electric
Allows driving using 100% electrical energy.
The maximum speed is approximately 84 mph
(135
km/h).
When starting the vehicle, if the conditions do
not allow the activation or retention of Electric
mode, the message "Electric mode currently
unavailable" is displayed on the instrument
panel. The vehicle automatically changes to
Hybrid mode.
If a blue LED comes on under the interior rear
view mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode.

workshop.
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.

Take care with objects or clothing that
could be caught in the blades of the fan!
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a pre-mixed
product.
In winter (temperatures below zero), a fluid
containing an anti-freeze agent which is
appropriate for the temperature conditions
must be used in order to protect the system's
components (pump, tank, ducts, jets).
Filling with pure water is prohibited in all
circumstances (risk of freezing,
limescale, etc.).
Diesel fuel additive (Diesel
with particle filter)
or On reaching the minimum level
in the particle filter additive tank,
this warning lamp comes on fixed, accompanied
by an audible signal and a warning message.
Topping up
This additive must be topped up without delay by
a CITROËN dealer or a qualified workshop.
AdBlue® (BlueHDi)
An alert is triggered when the reserve level is
reached.
For more information on the Indicators and in
particular the AdBlue range indicators, refer to
the corresponding section.
To avoid the vehicle being immobilised in
accordance with regulations, you must top up the
AdBlue tank.
For more information on AdBlue
® (BlueHDi),
and in particular the supply of AdBlue, refer to
the corresponding section.
Checks
Unless otherwise indicated, check these
components in accordance with the
manufacturer's service schedule and according
to your engine.
Otherwise, have them checked by a CITROËN
dealer or a qualified workshop.
Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, CITROËN selects and offers
very specific products.
12 V battery
The battery does not require any maintenance.
However, check regularly that the terminals
are correctly tightened (versions without quick
release terminals) and that the connections are
clean.
For more information on the precautions
to take before any work on the 12 V
battery, refer to the corresponding section.
Versions equipped with Stop & Start are
fitted with a 12 V lead-acid battery of
specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.

172
Practical information
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is essential to replace the
tyres.
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.
Shock absorbers
It is not easy for drivers to detect when
shock absorbers are worn. Nevertheless,
the shock absorbers have a major impact on
road-holding and braking performance.
For your safety and driving comfort, it is
important to have them regularly checked by a
CITROËN dealer or a qualified workshop.
Timing and accessory kits
Timing and accessory kits are used from the time the engine is started until it is
switched off. It is normal for them to wear over
time.
A faulty timing or accessory kit can damage
the engine, rendering it unusable. Observe the
Air filter
Depending on the environment and the
use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is
approaching saturation, this
warning lamp comes on temporarily,
accompanied by a message warning of the risk
of the filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37

mph (60 km/h) until the warning lamp
goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice
water vapour coming from the exhaust while
accelerating. These emissions have no
impact on the vehicle’s behaviour and the
environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic 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.
Electric parking brake
This system does not require any routine servicing. However, in the event of a
problem, do not hesitate to have the system
checked by a CITROËN dealer or a qualified
workshop.
For more information on the Electric
parking brake, refer to the
corresponding section.
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
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
