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.

Driving06
With Rechargeable hybrid
engines
Whenever the ignition is switched on, Electric
driving 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 an LED comes on under the interior rear view
mirror, visible from outside the vehicle, this
confirms that you are driving in Electric mode
(depending on country of sale).
The LED can be deactivated by inserting
the tip of a paper clip or other similar
object into the hole located underneath the
interior rear view mirror.
Conditions of activation
–

Adequa
te battery charge level. Charging
the vehicle after each drive is therefore

as there is power left in the battery.
–

O

utside temperature between approximately
-5°C and 45°C.
Manually exiting the mode
►  Fully depress the accelerator pedal, or
►  Select another mode.
In case of non-use of the vehicle for a long
period (several months), a restart of the
petrol engine may occur even if the battery is
charged.
Depending on equipment, Electric mode is
combined with Normal mode of the DS
ACTIVE SCAN SUSPENSION function.
For more information on DS ACTIVE SCAN
SUSPENSION, refer to the corresponding
section.
In the event of multiple starts of the
internal combustion engine without a
sufficient rise in
temperature,  Electric mode may be temporarily
unavailable (natural phenomenon of dilution of
fuel in oil). The message "Electric mode
unavailable: automatic operation in progress"
then appears on the instrument panel.
To regain normal electrical operation, drive
approximately 50 miles (80 km) in "motorway"
conditions or approximately 125 miles (200
km) in urban conditions.
This phenomenon does not cause any
mechanical or electrical damage. It can occur
several times in the life of the vehicle.
Hybrid
To optimise the vehicle's fuel consumption
by managing the alternating or simultaneous
operation of the two types of engine, depending
on driving conditions and driving style.
In Hybrid mode, it is possible to drive in 100%
electric mode if the battery charge level is
sufficient and acceleration requirements are
moderate.
Depending on equipment, Hybrid mode is
combined with Normal mode of the DS
ACTIVE SCAN SUSPENSION function.
For more information on DS ACTIVE SCAN
SUSPENSION, refer to the corresponding
section.
Sport
To obtain more dynamic driving in order to benefit
from the maximum performance of the vehicle.

Compatibility of fuels
Petrol fuels conforming to the EN228 standard
containing up to 5% and 10% ethanol respectively.

Diesel fuels conforming to the EN590, EN16734
and EN16709 standards and containing up to
7%, 10%, 20% and 30% fatty acid methyl ester
respectively. The use of B20 or B30 fuels, even
occasionally, imposes special maintenance
conditions referred to as "Arduous conditions".

Paraffinic Diesel fuel conforming to the EN15940
standard.
The use of any other type of (bio)fuel
(e.g. pure or diluted vegetable or animal
oils, domestic fuel) is strictly prohibited - risk
of damaging the engine and fuel system!
The only fuel additives authorised for use
are those that meet the B715001 (petrol)
or B715000 (Diesel) standards.
Diesel at low temperature
At temperatures below 0 °C (+32 °F), the
formation of paraffins in summer-type Diesel
fuels could prevent the engine from operating correctly. In these temperature conditions, use
winter-type Diesel fuel and keep the fuel tank
more than 50 % full.
At temperatures below -15 °C (+5 °F) to avoid
problems starting, it is best to park the vehicle
under shelter (heated garage).
Travelling abroad
Certain fuels could damage your vehicle’s engine.
In certain countries, the use of a particular fuel
may be required (specific octane rating, specific
trade name, etc.) to ensure correct operation of
the engine.
For all additional information, consult a dealer.
Refuelling
Fuel tank capacity: approximately 55
litres (Diesel), 62 litres (Petrol) or 43 litres
(Rechargeable hybrid).
Reserve level: approximately 6 litres.
Low fuel level
When the low fuel level is reached, this
warning lamp lights up on the instrument
panel, accompanied by the display of a message
and an audible signal. When it first comes on,
about 6 litres of fuel remain.
Until sufficient fuel is added, this warning lamp
appears every time the ignition is switched on,
accompanied by the message and the audible
signal. When driving, this message and audible
signal are repeated with increasing frequency as
the fuel level drops towards 0.
You must refuel as soon as possible to avoid
running out of fuel.
For more information on Running out of fuel
(Diesel), refer to the corresponding section.
A small arrow by the warning lamp
indicates which side of the vehicle the
fuel filler flap is located on.
Stop & Start
Never refuel with the engine in STOP
mode; you must switch off the ignition.
Refuelling
Any addition of fuel must be in quantities of at
least 10 litres, in order to be registered by the fuel
gauge.
Opening the filler flap may create a noise caused
by an inrush of air. This vacuum is entirely normal,
resulting from the sealing of the fuel system.
To refuel in complete safety:
►  Always switch off the engine.

Practical information07
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 level:
the correct level is between marks A (max) and
B (min).
Do not start the engine if the level is:
–

abo
ve mark A: contact a dealer or a qualified
workshop.
–

belo
w mark B: top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for your engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your dealer or qualified
workshop).
Use of non-recommended oil may invalidate
your warranty in the event of engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding engine compartment
illustration.
►  Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►  Wait a few minutes before checking the level
again using the dipstick.
►  Top up the level if necessary.
►  After checking the level, carefully screw the
oil filler cap back on and replace the dipstick in
its tube.
The oil level indication displayed on the
instrument panel when the ignition is
switched on is not valid for 30 minutes
following an addition of oil.
Brake fluid
The level of this fluid should be close to the
"MAX" mark. If not, check the brake pads
for wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT4 brake fluid from a sealed
container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with the
engine cold.
A level of coolant that is too low risks causing
major damage to the engine; the coolant level
must be close to the "MAX" mark without ever
going above it.
If the level is close to or below the "MIN" mark, it
is essential to top it up.
When the engine is hot, the temperature of the
coolant is regulated by the fan.
As the cooling system is pressurised, wait at least
one hour after switching off the engine before
carrying out any work.
In order to avoid the risk of scalding if you need to
top up in an emergency, wrap a cloth around the
cap and unscrew the cap by two turns to allow the
pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
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

163
Practical information07
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.
