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:

Instruments
1Dynamic stability control (DSC)/Anti-slip
regulation (ASR)
Flashing.
DSC/ASR regulation is activated in the
event of a loss of grip or trajectory.
Fixed.
The DSC/ASR system has a fault.
Carry out (3).
Emergency brake malfunction (with
electric parking brake)
Fixed, accompanied by the
message "Parking brake fault".
Emergency braking does not deliver optimal
performance.
If automatic release is not available, use manual
release or carry out (3).
Hill start assistFixed, accompanied by the
message "Anti roll-back system
fault".
The system has a fault.
Carry out (3).
Post Collision Safety BrakeFixed, associated with the
Service warning lamp,
accompanied by the display of a message and
an audible signal.
The system has a fault.
Carry out (3) quickly.
Under-inflationFixed.
The pressure in one or more tyres is too
low.
Check the pressure of the tyres as soon as
possible.
Reinitialise the detection system after adjusting
the pressure.
Under-inflation warning lamp
flashing then fixed and Service
warning lamp fixed.
The tyre pressure monitoring system is faulty.
Under-inflation detection is no longer monitored.
Check the tyre pressures as soon as possible
and carry out (3).
Parking sensorsFixed, accompanied by an onscreen
message and an audible signal.
The system is deactivated.
Fixed, associated with the Service
warning lamp, accompanied by the
display of a message and an audible signal.
The system has a fault.
Carry out (3).
Active bonnetFixed, accompanied by the display of a
message.
The active bonnet has been triggered.
Do not touch the bonnet.
Call a roadside assistance provider or carry
out (3) while driving no faster than 19 mph (30
km/h).
AirbagsFixed, accompanied by the display
of a message.
One of the airbags or seat belt pyrotechnic
pretensioners is faulty.
Carry out (3).
Front passenger airbag (ON)Fixed.
The front passenger airbag is activated.
The control is set to the “ON” position.
In this case, do NOT install a "rearward
facing" child seat on the front passenger seat
- risk of serious injury!
Front passenger airbag (OFF)Fixed.
The front passenger airbag is deactivated.
The control is set to the "OFF "
position.
A "rearward facing" child seat can be installed,
unless there is a fault with the airbags (Airbags
warning lamp on).
Low fuel levelFixed, with the reserve level shown in red,
accompanied by an audible signal and
the display of a message.
When it first comes on, you have approximately
6 litres of fuel remaining in the tank (reserve).
Until the fuel level is topped up, this alert will
be repeated every time the ignition is switched
on, with increasing frequency as the fuel level
decreases and approaches zero.
Refuel without delay to avoid running out of fuel.

Instruments
The range displayed depends on the use of the vehicle (type of driving and speed),
the outside temperature and the activated
comfort equipment.
Manual test
This function allows you to check certain
indicators and display the alerts log.
The test is launched in the Settings>Vehicle touch screen
application.
►

Then select
Safety>Check .
The following information is displayed on the
instrument panel:
–

Total distance recorder
The total distance recorder measures the total
distance travelled by the vehicle since its initial
registration.
With the ignition on, the total distance is
displayed at all times. It remains displayed for
30
seconds after switching off the ignition. It is
displayed when the driver's door is opened, and
when the vehicle is locked or unlocked.
When travelling abroad, it may be
necessary to change the distance units
(km or miles): the road speed must be
displayed in the local country’s official unit
(km/h or mph).
The unit is changed via the application of
screen settings, with the vehicle stationary.

The total distance recorder is only
accessible from the trip computer.
For more information on the Trip computer,
refer to the corresponding section.
