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.

switching

engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability. The
  condensation   created   by   the   air

If   after   an   extended   stop   in   sunshine,  
t

he   interior   temperature   is   very  
h

igh,   first   ventilate   the   passenger

f   the   six   gears.
The   gearbox   then   operates   in   auto-adaptive  
m

ode,   without   any   intervention   on   the   part  
o

f   the   driver.   It   continuously   selects   the   most  
s

uitable   gear   according   to   the   style   of   driving,  
t

he   profile   of   the   road   and   the   load   in   the  
v

ehicle.
For   maximum   acceleration   without   touching  
t

he   lever,   press   the   accelerator   pedal   down  
f

ully   (kick   down).   The   gearbox   changes   down  
a

utomatically   or   maintains   the   gear   selected  
u

ntil   the   maximum   engine   speed   is   reached.
On   braking,   the   gearbox   changes   down  a
utomatically   to   provide   efficient   engine  b
raking.
If you release the accelerator sharply, the
gearbox
  will   not   change   to   a   higher   gear   for  
s

afety   reasons.

Maintenance
In the event of a malfunction with the system, the "ECO OFF"   switch   warning   lamp   flashes,  
t

hen   comes   on   continuously.
Ha

ve   it   checked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Operating fault
This system requires a specific battery with   a   special   specification   and   technology  
(

reference numbers   available   from   a   CITROËN  
d

ealer   or   a   qualified   workshop).
Fitting
  a   battery   not   listed   by   CITROËN  
i

ntroduces   the   risk   of   malfunction   of   the  
s

ystem. Before
  doing   anything   under   the  
b

onnet,   deactivate   the   Stop   &   Start  
s

ystem   to   avoid   any   risk   of   injury  
r

esulting   from   automatic   operation   of  
S

TART   mode.
The   Stop   &   Start   system   makes   use  
o

f   advanced   technology.   All   work   on  
t

his   type   of   battery   must   be   done   only  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
In
 
the
 
event
 
of
 
a
 
fault
 
in
 
STOP
 
mode,
 
the
 v

ehicle
 
may
 
stall.
 
All
 
of
 
the

warning
 
lamps
 
come
 
on.
Depending
 
on
 
version,
 
an
 
alert
 
m

essage
 
may
 
also
 
be
 
displayed
 
asking
 
y

ou
 
to
 
put
 
the
 
gear
 
lever
 
into
 
position
 
N
and
 
put
 
your
 
foot
 
on
 
the
 
brake
 
pedal.
It is then necessary to switch off the
ignition,
 
then
 
restart
 
the
 
engine
 
using
 
t

he
 
key
 
or
 
the
 
"START/STOP"
 
button.
Reactivation
The system is reactivated automatically a t   every   new   start   using   the   key   or   the  
"

START/STOP"   button.
Press the "ECO OFF"
  switch   again.
The
 
system   is   active   again;   this   is   confirmed

check
 
these

(e.g.
  city   driving),   replace them twice as often
if necessary .
