8Eco-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.
Favour the use of the "Eco" driving mode by
selecting it using the "DRIVE MODE" control.
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 journe
y.


a
t each change of season.


a
fter 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
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).
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.

Ease of use and comfort03
►  Check that no person or object might interfere
with the folding of the backrests (e.g. clothing,
luggage).
►  Check that the outer seat belts are lying flat
on the backrests.
The folding of the backrest is
accompanied by a slight lowering of the
corresponding cushion.
To obtain a flat surface, it is necessary to place
the adjustable boot floor in the high position.
When the backrest is released, the red
indicator in the release grip is visible.
Folding from the passenger compartment

►  Press the backrest release grip 1.
►  Guide the backrest 3 down to the horizontal
position.
Folding from the boot

►  Pull the backrest release lever 2 towards you.
The backrest 3 folds fully onto the cushion.
Repositioning the backrests
First check that the outer seat belts are
lying vertically flat alongside the backrest
latching rings.


►  Straighten the backrest 3 and push it firmly to
latch it into place.
►  Check that the red indicator is no longer
visible in the release grip 1.
►  Ensure that the outer seat belts were not
trapped during the operation.
Please note: an incorrectly latched
backrest compromises the safety of
passengers in the event of sudden braking or
an accident.
The contents of the boot may be thrown
forwards - risk of serious injury!
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 together on the centre console
panel.

Advice
Using the ventilation and air conditioning
system
►  To 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 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. Its specific active additive
helps protect against polluting gases and bad
smells.
►  To ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Manufacturer’s service schedule.
Stop & Start
The heating and air conditioning systems
only operate when the engine is running.
Temporarily deactivate the Stop & Start
system to maintain a comfortable temperature
in the passenger compartment.
For more information on the Stop &
Start system, refer to the corresponding
section.
Rechargeable hybrid vehicles
Intensive use of the air conditioning
reduces the vehicle range in Electric mode.
Ventilation with the ignition on
When the ignition is switched on, the ventilation
system and the air flow 2 and air distribution
3 settings in the passenger compartment are

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

minimum, ventilation stops.
“OFF" is displayed alongside the fan.
Adjusting the air distribution
►  Press the buttons 3 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.
►  To activate/deactivate the function, press
button 7.
AQS function
Using an exterior pollution sensor, this function
automatically activates the recirculation of
interior air when a certain level of pollutants in
the exterior 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 pollution sensor, this function
detects fine particles (e.g. cigarette smoke,
mould, bacteria).
The management of the recirculation 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 high-
performance passenger compartment filter.
If the air quality appears to be reduced, contact a
dealer or a qualified workshop to change the high-
performance passenger compartment filter.
Air conditioning on/off
The air conditioning system is designed to
operate effectively in all seasons, with the
windows closed:


It lo

Diesel fuel system
This system is under very high pressure.
All work must be carried out only by a dealer or
a qualified 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 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 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.

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)
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
The topping up of this additive must be carried
out quickly.
Visit a 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 dealer or a
qualified workshop.
Only use products recommended by the
Manufacturer or products of equivalent
quality and specification.
In order to optimise the operation of
components as important as those in the
braking system, the Manufacturer 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 with
special technology and specifications.
Its replacement should be carried out only by a
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.
Particle filter (Diesel)
The start of clogging of the particle filter is
indicated by the temporary lighting of this
warning lamp, accompanied by an alert message.
As soon as traffic conditions allow, regenerate
the filter by driving at a speed of at least 37 mph
(60 km/h), with an engine speed above 2,500
rpm, for about 15 minutes (until the warning lamp
goes out).
If it is not possible to reach 37 mph (60 km/h),
leave the engine running at idle for about 15
minutes, then drive with an engine speed above
2,500 rpm for 15 minutes.
