7Eco-driving
Eco-driving
Eco-driving refers to a range of everyday practices
that allow the motorist to optimise their fuel
consumption and CO
2emissions.
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 and avoid pressing the accelerator pedal
heavily or suddenly.
The gear efficiency 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 attitudes
help to save fuel, 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.
If the vehicle has the steering-mounted "CRUISE"
control, use cruise control at speeds above 25
mph (40 km/h) when the traffic is flowing well.
Use electrical equipment wisely
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.
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.
Switch off the headlamps and foglamps when the
visibility conditions do not require their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving.
As a passenger, avoid connecting your multimedia
devices (film, music, video game, etc.) to help
reduce consumption of electrical energy, and
hence fuel.
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 (roof bars, roof rack, bicycle
carrier, trailer, etc.). 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 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 overlook the spare wheel and, where
applicable, the tyres on your trailer or caravan.
Have your vehicle serviced regularly (engine oil,
oil filter, air filter, passenger compartment filter,
etc.) and 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
dealer or a qualified workshop as soon as possible
to restore your vehicle’s nitrogen oxide emissions
to regulatory compliance.
When filling the fuel tank, do not continue after
the third nozzle cut-out, 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).

With the engine running:
– In z one A, the temperature is correct.
–

In z
one B, the temperature is too high; the
associated warning lamp and the central STOP
warning lamp come on in red on the instrument
panel, accompanied by the display of a message
and an audible signal.
You must stop the vehicle as soon as it is safe to
do so.
Wait a few minutes before switching off the
engine.
After switching off the ignition, carefully
open the bonnet and check the coolant
level.
For more information on Checking levels,
refer to the corresponding section.
AdBlue® range indicators
(BlueHDi)
The Diesel BlueHDi engines are equipped with
a system that associates the SCR (Selective
Catalytic Reduction) emissions control system
and the Diesel particle filter (DPF) for the
treatment of exhaust gases. They cannot function
without AdBlue
® fluid.
When the level of AdBlue® falls below the reserve
level (between 1,500 and 0 miles (2,400 and
0 km)), a warning lamp lights up when the ignition
is switched on and an estimate of the distance
that can be travelled before engine starting is
prevented is displayed in the instrument panel.
The engine starting prevention system
required by regulations is activated
automatically once the AdBlue
® tank is empty.
It is then no longer possible to start the engine
until the minimum level of AdBlue
® has been
topped up.
Manual display of the range
While the driving range is greater than 1,500 miles
(2,400 km), it is not displayed automatically.
You can view the range information by
pressing the "Check" button in the touch
screen’s Driving / Vehicle menu.
Actions required related to a lack of
AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reserve level
corresponding to a range of 1,500 miles (2,400
km).
Together with the warning lamps, messages
regularly remind you of the need to top up to avoid
engine starting being prevented. Refer to the
Warning and indicator lamps section for details of
the messages displayed.

Malfunction of the SCR emissions control
system
Malfunction detection


If a malfunction is detected,
these warning lamps come on,
accompanied by an audible
signal and an "Emissions fault”
message.
The alert is triggered while driving, when the fault
is detected for the first time, and thereafter when
switching on the ignition for subsequent journeys,
while the cause of the fault persists.
If the fault is temporary, the alert
disappears during the next journey, after
self-diagnostic checks of the SCR emissions
control system.
Malfunction confirmed during the permitted
driving phase (between 685 miles and 0 miles
(1,100 km and 0 km))
If the fault indication is still displayed
permanently after 31 miles (50 km) of driving, the
fault in the SCR system is confirmed.
The AdBlue warning lamp flashes, and an 
"Emissions fault: Starting prevented in X miles”
message is displayed, indicating the driving range
in miles or kilometres.
While driving, the message is displayed every 30
seconds. The alert is repeated when switching on
the ignition.
You can continue driving for up to 685 miles
(1,100 km) before the engine immobiliser system
is triggered.
Have the system checked by a dealer or a
qualified workshop as soon as possible.
Starting prevented
Whenever the ignition is switched on, the
"Emissions fault: Starting prevented” message is
displayed.
To be able to restart the engine, contact a
dealer or a qualified workshop.

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 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.
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).
►  To ensure correct operation of the
air conditioning system, have it checked
according to the recommendations in the
Maintenance and Warranty Guide.
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, refer
to the corresponding section.

– increase the effectiveness of the demisting in
winter, above 3°C.
►  Press button 4 to activate/deactivate the air
conditioning system.
Air conditioning does not operate when
the air flow is disabled.
To obtain cool air more quickly, enable interior
air recirculation for a brief period. Then return
to the intake of exterior air.
Switching off the air conditioning may result in
some discomfort (humidity or misting).

Deactivation / Reactivation
In exceptional conditions (starting a vehicle stuck
in mud, immobilised in snow, on soft ground, etc.),
it may be useful to deactivate the ASR system to
freely spin the wheels and regain traction.
Reactivate the system as soon as the level of grip
permits.
It is set via the Driving / Vehicle touch
screen menu.
Deactivation is confirmed by the
illumination of this indicator lamp in the
instrument panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 31 mph (50 km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this
warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a dealer or a qualified workshop to have
the systems checked.
ASR / DSC
These systems enhance safety during
normal driving, but should not encourage the
driver to take extra risks or drive at high speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
For technical reasons, in particular to
improve the quality of telematic services
for customers, the Manufacturer reserves the
right to carry out updates to the vehicle's
on-board telematic system at any time.
If you benefit from the DS CONNECT BOX
offer with the SOS and Assistance Pack
included, you have available additional
services in your personal space, via the
website in your country.
For information about the SOS and Assistance
Pack, please refer to the general conditions for
these services.
Electronic stability control
(ESC)
The electronic stability control programme
includes the following systems:
–

An
ti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–

Emergenc
y braking assistance (EBA).
–

An
ti-slip regulation (ASR).
–

Dynamic st
ability control (DSC).
Anti-lock braking system (ABS)
and Electronic brake force
distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the
event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a dealer or a qualified workshop as soon
as possible.
This warning lamp, when lit together with
the STOP and ABS warning lamps,
accompanied by a message and an audible signal,
indicates an EBFD malfunction.
You must stop as soon as it is safe to do so.
Contact a dealer or a qualified workshop.
The normal operation of the ABS may
result in slight vibrations in the brake
pedal.
When braking in an emergency, press very
firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a dealer or a qualified
workshop.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach
the optimum braking pressure more quickly and
therefore reduce the stopping distance.
It is triggered in relation to the speed at which the
brake pedal is pressed. This is felt by a reduction
in the resistance of the pedal and an increase in
braking efficiency.
Anti-slip regulation (ASR) /
Dynamic stability control (DSC)
Anti-slip regulation optimises traction using
engine braking and by applying the brakes on the
driving wheels to avoid wheel spinning. It also
enhances the vehicle's directional stability while
accelerating.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
They come into operation in the event of a grip or
trajectory problem.
This warning lamp on the instrument panel
flashes to indicate that they are operating.

80Driving06
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
►  Monitor your environment and keep your
hands on the wheel to be able to react to anything
that may happen any time.
►  Drive smoothly, anticipate the need for braking
and maintain a longer safety distance, especially
in bad weather.
►  Stop the vehicle to carry out operations that
require close attention (such as adjustments).
►  During long trips, take a break every two
hours.
Important!
Never leave the engine running in a closed
space without sufficient ventilation.
Internal combustion engines emit toxic
exhaust gases such as carbon monoxide.
Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied. Risk of overheating and damage
to the braking system!
Do not park the vehicle or leave the engine
running on a flammable surface (dry
grass, dead leaves, etc.). The exhaust system
of your vehicle is very hot, even several
minutes after the engine stops. Risk of fire!
Never leave a vehicle unattended with the
engine running. If you have to leave your
vehicle with the engine running, apply the
parking brake and put the gearbox into neutral
or position N or P (depending on the type of
gearbox).
Never leave children inside the vehicle
unsupervised.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to the
engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
►  check that the depth of water does not exceed
15 cm, taking account of waves that might be
generated by other users,
►  deactivate the Stop & Start function,
►  drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
►  do not stop and do not switch off the engine.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, contact
a dealer or a qualified workshop.
Noise (Electric)
On the outside
Due to the vehicle’s quiet operation when driving,
the driver should pay particular attention.
At speeds of up to 19 mph (30 km/h), the
pedestrian horn warns other road users of the
vehicle’s presence.
Cooling the traction battery
The cooling fan comes on during charging
to cool the on-board charger and the traction
battery.
On the inside
During use, you may hear certain perfectly normal
noises specific to electric vehicles, such as:
–

Traction ba
ttery relay when starting.
–

V
acuum pump when braking.
–

V
ehicle tyres or aerodynamics when driving.
– Jolting and knocking noise during hill starts.
Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by 10%
per 1,000 metres of altitude; the lower air
density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has driven at least 620 miles
(1,000 kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
►  Distribute the load in the trailer so that the
heaviest items are as close as possible to the axle
and the nose weight (at the point where it joins
your vehicle) approaches the maximum permitted
without exceeding it.
