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.

When
  the   driver’s   door   is   opened   with   the  
e

ngine   running,   a   message   is   displayed  
a

ccompanied   by   an   audible   signal   if   the   parking  
b

rake   has   not   been   applied,   except   in   the   case  
o

f   an   automatic   gearbox   with   the   gear   lever   in  
p

osition P .
Before
  leaving   the   vehicle,   ensure
 t

hat   parking   brake   warning   lamp   in   the
 i

nstrument   panel   is   on   fixed,   not   flashing.
Manual applicationManual release
The full application of the parking brake is c
onfirmed   by:
-
 
t
he   braking   warning   lamp   and  
t

he P   warning   lamp   in   the   control  
l

ever A   going   off,
-
 
d
isplay   of   the   message   "Parking  
b

If you pull control lever A  without   pressing t
he   brake   pedal,   the   parking   brake   will n

ot   be   released   and   a   warning   lamp   will
 c

ome   on   in   the   instrument   panel.
With the ignition on or the engine running, to release   the   parking   brake,   press on the brake
pedal or the accelerator, pull then release
control A . If
  necessary,   you   can   make   a   maximum
application
 
of   the   parking   brake.   This   is  
o

btained
 by m
eans
 o
f
 a long
pull
on the control
lever A ,   until   you   see   the   message   "Parking  
b

rake   on   maximum"   and   a   beep   is   heard.
In   the   case   of   towing,   a   loaded   vehicle   or  
p

arking   on   a   gradient,   make   a   maximum  
a

pplication   of   the   parking   brake   then   turn   the  
f

ront   wheels   towards   the   pavement   and   engage  
a

  gear   when   you   park.
After
  a   maximum   application,   the   release   time  
w

ill   be   longer.
Maximum application
Maximum application is essential:
- i n   the   case   of   a   vehicle   towing   a   caravan  
o

r   a   trailer,   if   the   automatic   functions   are  
a

ctivated   but   you   are   applying   the   parking  
b

rake
 m
anually,
-
 
w
hen   the   gradient   you   are   parked   on   may  
v

ary   (e.g.   on   a   ferry,   on   a   lorry,   during  
tow

ing).

In addition to the rear parking sensors, the front parking   sensors   are   triggered   when   an   obstacle i

s   detected   in   front   and   the   speed   of   the   vehicle   is
 s

till   below   6   mph   (10   km/h).
The
  front   parking   sensors   are   interrupted   if   the
 v

ehicle   stops   for   more   than   three   seconds   in
 f

or ward   gear,   if   no   further   obstacles   are   detected
 o

r   when   the   speed   of   the   vehicle   exceeds   6   mph
 (

Deactivation/Activation of the
front and rear parking sensors
The function is deactivated by pressing this button.   The   indicator   lamp   in   the   button  
comes

Towing a trailer
Your vehicle is primarily designed for transporting   people   and   luggage,   but   it   may  
a

lso   be   used   for   towing   a   trailer.
Driving
  with   a   trailer   places   greater   demands  
o

n   the   towing   vehicle   and   the   driver   must   take  
par

ticular
 c
are.Driving advice
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.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
Refer
  to   the   "Technical   data"   section   for   details  
o

f   the   weights   and   towed   loads   which   apply   to  
y

our   vehicle.
We
 
recommend
 
the
 
use
 
of
 
genuine
 
C

ITROËN
 
towbars
 
and
 
their
 
harnesses

F If  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   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   is   recommended.
Ty r e s
F Check   the   tyre   pressures   of   the  
towing   vehicle   and   of   the   trailer,   observing  
t

he
 re
commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.
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   
c
oolant  
t

emperature.
