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.

the

When

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
conditioning
  results   in   a   discharge  
o

f water under the vehicle which is
per 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

ontain chlorine and does not present
any   danger   to   the   ozone   layer.

Moving off
If position N is engaged inadvertently while   driving,   allow   the   engine   to  
r

eturn   to   idle   then   engage   position   D to
accelerate. F

Sel
ect position D for automatic
 c
hanging
 o

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
vehicle.
For
  maximum   acceleration   without   touching  
t

he selector, press the accelerator pedal down
fully
  (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   effective   engine  
b

raking.
If you release the accelerator sharply, the
gearbox
  will   not   change   to   a   higher   gear   for  
s

afety   reasons.
When
  the   engine   is   running   at   idle,   with  
t

he   brakes   released,   if   position   R,
D
or
M   is   selected,   the   vehicle   moves  
e

ven   without   the   accelerator   being  
p

ressed.
Never leave children unsupervised in
the
  vehicle   when   the   engine   is   running.
When
  carrying   out   maintenance   with  
t

he   engine   running,   apply   the   parking  
b

rake   and   select   position   P.
Never select position N while the
vehicle
  is   moving.
Never select positions P or R unless the
vehicle
  is   completely   stationary.
