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 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 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.
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.
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).
Optimising the driving range
(rechargeable hybrid vehicles)
Connect the vehicle as soon as possible.
Favour the ECO zone of the power indicator by
driving smoothly and at a steady speed.
Anticipate slowing down as much as possible
and, if possible, favour decelerations with
regenerative braking mode activated (power
indicator in the CHARGE zone).
With the vehicle connected, carry out
temperature pre-conditioning before setting off.
To optimise consumption during a journey:

3► Press the button 2 and tilt the backrest
forwards or backwards to obtain the desired
angle.
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 through the Climate touch screen application and are
also grouped on the centre console panel.
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
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 good working order

.
►

If the system does not produce cold air
,
switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing a large 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.
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

Ease of use and comfort
3– "AUTO SOFT": provides soft and quiet
operation by limiting air flow .
–
"AUTO NORMAL": offers the best
compromise between a comfortable temperature
and quiet operation (default setting).
–
"AUTO FAST": provides dynamic and efficient
air distribution.
To change the AUTO mode, press button 9
successively.
To ensure passenger comfort in the rear seats,
favour settings AUTO NORMAL and AUTO
FAST.
In cold weather with the engine cold, the
air flow is increased gradually until the
comfort setting has been reached, in order to
limit the delivery of cold air into the passenger
compartment.
On entering the vehicle, if the interior
temperature is much colder or warmer than
the comfort setting requested, there is no
need to alter the value displayed to more
quickly reach the required level of comfort.
The system automatically corrects the
temperature difference as quickly as possible.
Automatic air conditioning manual settings
It is possible to manually adjust one or more
of these functions, while the system retains
automatic control of the other functions:
–

air flow
.
– air distribution.
The indicator lamp in the " AUT
O" button goes
out is a setting is changed.
►

central controls go off.
Adjusting the air distribution
► Press the buttons 8 to adjust the air flow
distribution inside the passenger compartment.
Windscreen and side windows
Central and side air vents
Footwells
A symbol is activated to display the presence of
blown air in the direction indicated. It is possible
to activate all three buttons simultaneously, for
uniform distribution throughout the passenger
compartment.
Clean Cabin function
It includes the AQS (Air Quality System) and
Clean Air functions.
►
T
o activate/deactivate the function, press
button 11 .
AQS function
Using an exterior air quality sensor, this function
automatically activates the recirculation of
interior air when a certain level of pollutants in
the outdoor air is detected.
When the air quality returns to a satisfactory
level, recirculation of interior air is automatically
deactivated.
This function is not designed to detect
unpleasant odours.
Recirculation is automatically activated when the
windscreen wash is used or when reverse gear
is engaged.
The function is inactive if the outside temperature
is below 5°C to prevent the risk of misting on the
windscreen and side windows.
Clean air function
Using an interior air quality sensor, this function
detects fine particles (e.g.
cigarette smoke).
Recirculation management of interior air makes
it possible to return to a purified passenger
compartment in just a few minutes, thanks
to the passage of air through the passenger
compartment filter.

52
Ease of use and comfort
If the air quality appears to be reduced, consult
a CITROËN dealer or a qualified workshop to
change the passenger compartment filter.
Air conditioning on / off
The air conditioning is designed to operate
effectively in all seasons, with the windows
closed.
It lowers the temperature in summer.
It increase the effectiveness of the demisting, in
winter, above 3°C.
►
Press knob
1 to switch the air conditioning
on/off.
When the system is activated, the indicator lamp
of the button comes on.
Air conditioning does not operate when the air flow is deactivated.
To obtain cool air more quickly, enable interior
air recirculation for a a brief period. Then
return to the intake of exterior air.
Switching off air conditioning may result in
some discomfort (humidity, misting).
Maximum air conditioning
This function automatically adjusts the
temperature setting to the lowest possible, the
air distribution towards the central and side air
vents, the air flow to maximum and activates
interior air recirculation.
► Press knob 2 to activate/deactivate the
function (the indicator lamp will come on/switch
off).
Once the function is deactivated, the system
returns to the previous settings.
Interior air recirculation
The intake of exterior air prevents the formation
of mist on the windscreen and side windows.
Recirculating the interior air isolates the
passenger compartment from outside odours
and fumes and allows the desired passenger
compartment temperature to be achieved more
rapidly.
► Press this button to activate/deactivate
the function (confirmed by the
illumination/extinction of the indicator lamp).
This function is activated automatically when reverse gear is engaged.
Front demisting
- defrosting
This mode allows the windscreen and side windows to be demisted or defrosted as quickly
as possible.
► Press this button to activate/deactivate
the mode (confirmed by the illumination/
extinction of the indicator lamp).
It automatically manages the air conditioning
(depending on version), air flow and air intake,
and provides optimum distribution towards the
windscreen and side windows.
It is possible to manually change the air flow
without deactivating the mode.
With Stop & Start, when demisting has
been activated, STOP mode is not
available.
In wintry conditions, before moving off,
remove all snow or ice on the windscreen
near the camera.
Otherwise, the operation of the equipment
using the camera may be affected.
Rear screen demisting/
defrosting
This demisting/defrosting only works with the engine running.
It also demists/defrosts the doors mirrors.
► Press this button to activate/deactivate
the function (confirmed by the
illumination/extinction of the indicator lamp).
The function can be activated whatever the outside temperature may be.
The period of operation depends on the outside
temperature.

illustrative purposes only.
The locations of the following elements may
vary:
–
Air filter
.
–

Engine oil dipstick.
–


Engine oil filler cap.

2. Engine coolant reservoir
3. Brake fluid reservoir
4. Battery/Fuses
5. Remote earth point (-)
6. Fusebox
7. Air filter
8. Engine oil filler cap
9. Engine oil dipstick
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.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
►

Grasp the dipstick by its coloured grip and
pull it out completely

.
►

Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil

160
Practical information
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.
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.
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.
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
