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   in   the   personalised   servicing   schedule   for   your   vehicle.
With
  a   BlueHDi   Diesel   engine,   if   the   SCR   system   develops   a   fault,  
y

our   vehicle   becomes   polluting;   go   to   a   CITROËN   dealer   or   a   qualified  
w

orkshop   without   delay   to   have   the   emissions   of   nitrous   oxides   brought  
w

ithin   the   limits   set   by   the   directive.
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.

Operation
When this warning lamp comes on, accompanied   by   an   audible   signal  
a

When towing
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that   the  h
eaviest   items   are   as   close   as   possible   to  
t

he   axle   and   the   nose   weight   approaches  
t

he   maximum   permitted   without  
e

xceeding it.
Air
  density   decreases   with   altitude,   thus  
r

educing   engine   per formance.   Above  
1 0

00 metres,   the   maximum   towed   load   must  
b

e   reduced   by   10 %   for   every   1 000   metres   of  
al

titude.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
Cooling
Towing a trailer on a slope increases the temperature   of   the   coolant.
As
  the   fan   is   electrically   controlled,   its   cooling  
c

apacity   is   not   dependent   on   the   engine   speed.
F
 
T
o   lower   the   engine   speed,   reduce   your  
s

peed.
The
  maximum   towed   load   on   a   long   incline  
d

epends   on   the   gradient   and   the   ambient  
t

emperature.
In
  all   cases,   keep   a   check   on   the   coolant  
t

emperature. F
 
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   engine   as   soon   as   possible.
Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes,   the   use   of  
e

ngine   braking   is   recommended.
Ty r e s
F Check  the   tyre   pressures   of   the   towing  v
ehicle   and   of   the   trailer,   observing   the  
re

commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer   and   the   hadlamp   beam   height  
o

f   your   vehicle.
For
  more   information   on   adjusting   the  
h

eadlamp   beam   height,   refer   to   the  
c

orresponding
 s
ection.
The
  rear   parking   sensors   will   be

Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  
p

articularly   under   arduous   condition  
(

high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
For
  more   information   on   the  
i

dentification   markings,   refer   to   the  
c

orresponding
 s
ection.
Tyre
  pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Under-inflation alertReinitialisation
Before reinitialising the system, ensure t
hat the pressures of the four tyres are
correct
  for   the   use   of   the   vehicle   and   in  
l

ine   with   the   recommendations   on   the  
t

yre   pressure   label.
The
  under-inflation   alert   can   only  
b

e   relied   on   if   the   reinitialisation   of  
t

he   system   has   been   done   with   the  
p

ressures in the four tyres correctly
adjusted.
The
  under-inflation   detection   system  
d

oes   not   give   a   warning   if   a   pressure   is  
i

ncorrect   at   the   time   of   reinitialisation.
