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.

Air intake
The air circulating in the passenger compartment   is   filtered   and   originates   either

to
 
the
 
purification
 
of

by
 
the

the
 
cleanliness

you
 
are

advised
 
to
 
have

as
 
recommended
 
in

guide.

the

When

on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the

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

ompartment.
The   air   conditioning   system   does   not  
c

ontain   chlorine   and   does   not   present  
a

with
 
the
 
manufacturer's
 
service
 
schedule
 
and   according   to   your   engine.

The battery does not require any maintenance.
H owever,   check   that   the   terminals   are   clean a

nd   correctly   tightened,   particularly   in   summer
 a

nd   winter.
When carrying out work on the battery, refer to   the   "12 V   battery"   section   for   details   of   the  
p

recautions   to   be   taken   before   disconnecting  
t

he   battery   and   following   its   reconnection.Depending
  on   the   environment   (e.g.   dusty  a
tmosphere)   and   the   use   of   the   vehicle  
(e.g.
  city   driving),   replace them twice as often
if necessary .
A
  clogged   passenger   compartment   filter   may  
h

ave   an   adverse   effect   on   the   per formance  
o

f   the   air   conditioning   system   and   generate  
u

ndesirable
 o
dours.The start of saturation of the particle filter is
indicated

ew vehicle, the first operations of
regeneration
  of   the   particle   filter   may   be

ccompanied   by   the   smell   of   "burning",  
w

hich   is   per fectly   normal.
Following
  prolonged   operation   of   the  
v

ehicle   at   very   low   speed   or   at   idle,  
y

ou   may,   in   exceptional   circumstances,  
n

otice   the   emission   of   water   vapour   at  
t
