C4-2_en_Chap00c_eco-conduite_ed02-2015
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   gearbox,   give   preference   to   automatic   mode   and  
a

void   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   CO
2
emissions
 
and
 
also
 
helps
 
reduce
 
the
 
background
 
traffic
 
noise.
If
 
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 b y   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 shift 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   automatic   gearbox,   this   indicator   appears  
o

nly   in   manual   mode.
Eco-driving

11
C4-2_en_Chap00c_eco-conduite_ed02-2015
Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the bottom   of   the   boot,   as   close   as   possible   to   the   rear   seats.
Limit
  the   loads   carried   in   the   vehicle   and   reduce   wind   resistance   (roof  
b

ars,   roof   rack,   bicycle   carrier,   trailer...).   Use   a   roof   box   in   preference.
Remove
  roof   bars   and   roof   racks   after   use.
At
  the   end   of   winter,   remove   snow   tyres   and   refit   your   summer   tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in the   door   aperture,   driver's   side.
Carry
  out   this   check   in   particular:
-
 
b
efore   a   long   journey,
-
 
a
t   each   change   of   season,
-
 
a
fter   a   long   period   out   of   use.
Don't
  forget   the   spare   wheel   and   the   tyres   on   any   trailer   or   caravan.
Have
  your   vehicle   serviced   regularly   (engine   oil,   oil   filter,   air   filter,  
p

assenger   compartment   filter...)   and   observe   the   schedule   of  
o

perations   recommended   in   the   manufacturer's   service   schedule.
With
  a   BlueHDi   Diesel   engine,   if   the   SCR   system   is   faulty   your   vehicle  
b

ecomes   polluting;   go   to   a   CITROËN   dealer   or   a   qualified   workshop  
w

ithout   delay   to   have   the   emissions   of   nitrous   oxides   brought   back   to  
t

he   legal   level.
When
  refuelling,   do   not   continue   after   the   third   cut-off   of   the   nozzle   to  
a

void   any   over flow.
At
  the   wheel   of   your   new   vehicle,   it   is   only   after   the   first   1   800   miles  
(

3 000   kilometres)   that   you   will   see   the   fuel   consumption   settle   down   to  
a

  consistent   average.

Depending on the driving situation and your vehicle's   equipment,   the   system   may   advise  
y

ou   to   skip   one   (or   more)   gear(s).   You   can  
f

ollow   this   instruction   without   engaging   the

The

n

ot   be   considered   compulsory.   In   fact,   the  
c

onfiguration   of   the   road,   the   amount   of   traffic  
a

nd   safety   remain   determining   factors   when  
c

hoosing   the   best   gear.   Therefore,   the   driver
