fuel consumption Citroen C4 2014.5 2.G Owner's Manual

10
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.
Eco-driving

11
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.

Gear efficiency indicator*
Depending on the driving situation and your v

The

c

onfiguration   of   the   road,   the   amount   of   traffic  
a

nd   safety   remain   determining   factors   when

Tyre under-inflation detection
System which automatically checks the p
ressures   of   the   tyres   while   driving.
The
  system   continuously   monitors   the  
p

ressures of the four tyres, as soon as the
vehicle
  is   moving.
A
  pressure   sensor   is   located   in   the   valve   of  
e

ach   tyre   (except   the   spare   wheel).
The
  system   triggers   an   alert   if   a   drop   in  
p

ressure   is   detected   in   one   or   more   tyres.
The
  tyre   under-inflation   detection   system   is   an  
a

id   to   driving   which   does   not   replace   the   need  
f

or   vigilance   on   the   part   of   the   driver.This
  system   does   not   avoid   the   need  
t

o   check   the   tyre   pressures   regularly  
(

including   the   spare   wheel)   and   before  
a

  long   journey.
Driving   with   under-inflated   tyres  
a

dversely   affects   road   holding,  
e

xtends   braking   distances   and   causes  
p

remature   tyre   wear,   particularly   under  a
rduous   conditions   (vehicle   loaded,  h
igh   speed,   long   journey).The tyre pressures for your vehicle can
be
  found   on   the   tyre   pressure   label   (see  
t

he   "Identification   markings"   section).
The   tyre   pressures   must   be   checked  
w

hen   the   tyres   cold   (vehicle   stopped  
f

or   1   hour   or   after   driving   for   less   then  
6

  miles   (10   km)   at   moderate   speed).  
O

ther wise,   add   0.3   bar   to   the   values  i
ndicated   on   the   label.
Driving   with   under-inflated   tyres

ncreases   fuel   consumption.
