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 change up without waiting. During   acceleration   change   up   early.
With
  an   automatic   or   electronic   gearbox,   give   preference   to   automatic  
m

ode   and   avoid   pressing   the   accelerator   pedal   heavily   or   suddenly.
Drive smoothly
Maintain a safe distance between vehicles, use engine braking rather than   the   brake   pedal,   and   press   the   accelerator   progressively.   These  
p

ractices   contribute   towards   a   reduction   in   fuel   consumption   and  
C

o
2 emissions and also helps reduce the background traffic noise.
I
f
 
your   vehicle   has   cruise   control,   make   use   of   the   system   at   speeds  
a

bove   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
  30   mph   (50   km/h),   close   the   windows   and   leave   the   air   vents
 ope

n.
Remember
  to   make   use   of   equipment   that   can   help   keep   the
 t

emperature   in   the   passenger   compartment   down   (sunroof   and   window
 b

linds...).
Switch
  off   the   air   conditioning,   unless   it   has   automatic   regulation,   as
 s

oon   as   the   desired   temperature   is   attained.
Switch
  off   the   demisting   and   defrosting   controls,   if   not   automatic.
Switch
  off   the   heated   seat   as   soon   as   possible.
Switch
  off   the   headlamps   and   front   foglamps   when   the   level   of   light  
d

oes   not   require   their   use.
Avoid
  running   the   engine   before   moving   off,   particularly   in   winter;   your  
v

ehicle   will   warm   up   much   faster   while   driving.
As
  a   passenger,   if   you   avoid   connecting   your   multimedia   devices  
(

film,   music,   video   game...),   you   will   contribute   towards   limiting   the  
c

onsumption   of   electrical   energy,   and   so   of   fuel.
Disconnect
  your   portable   devices   before   leaving   the   vehicle.
Eco-driving
The gear efficiency indicator invites you engage the most suitable gear: as   soon   as   the   indication   is   displayed   in   the   instrument   panel,   follow   it  
s

traight   away.
For
  vehicles   fitted   with   an   electronic   or   automatic   gearbox,   this  
i

ndicator   appears   only   in   manual   mode.

Stop & Start
The heating and air conditioning systems   only   work   when   the   engine  
i

s   running.   To   maintain   a   comfortable  
t

emperature   in   the   passenger  
c

ompartment,   you   can   temporarily  
d

eactivate   the   Stop   &   Start   system   (see  
t

he   corresponding   section).

the

When
 
towing
 
the
 
maximum
 
load
 
on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the
 a
ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability. The
  condensation   created   by   the   air  
c

onditioning   results   in   a   discharge  
o

f   water   under   the   vehicle   which   is  
p

er fectly   normal.
If   after   an   extended   stop   in   sunshine,  
t

he   interior   temperature   is   very  
h

igh,   first   ventilate   the   passenger  
c

ompartment   for   a   few   moments.
Put   the   air   flow   control   at   a   setting   high  
e

nough   to   quickly   change   the   air   in   the  
p

assenger

The   air   conditioning   system   does   not  
c

ontain   chlorine   and   does   not   present  
a

ny   danger   to   the   ozone   layer.
