As a passenger, if you avoid connecting your
m ultimedia devices (film, music, video game,
etc.), you will contribute towards limiting the
consumption of electrical energy, and so of
fuel.
Disconnect your portable devices before
leaving the vehicle.
Eco- driving
Eco-driving is a range of everyday practices that allow the motorist to optimise their fuel consumption and CO2 emissions.
Optimise the use of your gearbox
With a manual gearbox, move off gently and
c hange up without waiting. While accelerating,
change up early.
With an automatic gearbox, give preference
to automatic mode and avoid pressing the
accelerator pedal heavily or suddenly.
The gear efficiency indicator invites you to
engage the most suitable gear: as soon as the
indication is displayed in the instrument panel,
follow it straight away.
For vehicles fitted with an automatic gearbox,
this indicator appears only in manual mode.
Drive smoothly
Maintain a safe distance between vehicles,
u se engine braking rather than the
brake pedal, and press the accelerator
progressively. These practices contribute
towards a
reduction in fuel consumption and
CO
2 emissions and also help reduce the
b
ackground traffic noise.
If your vehicle has cruise control, make use of
the system at speeds above 25
mph (40 km/h)
when the traffic is flowing well.
Control the use of your 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.
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 (sunroof blind and window
blinds, etc.). Switch off the headlamps and front foglamps
when the ambient light level does not require
their use.
Avoid running the engine before moving off,
particularly in winter; your vehicle will warm up
much faster while driving. Unless it has automatic regulation, switch off
the air conditioning as soon as the desired
temperature has been reached.
Switch off the demisting and defrosting
controls, if these are not automatically
managed.
Switch off the heated seat as soon as
possible.

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.
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 range is greater than 1,500 miles
( 2,400 km), it is not displayed automatically.
F

P
ress this button to temporarily display the
driving range.
Actions required related to a lack
of AdBlue®
The following warning lamps light up when the
quantity of AdBlue® is lower than the reser ve
level corresponding to a range of 1,500 miles
(2, 4 0 0


k m).
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.
