Special position of the
windscreen wipers
This position permits release of the windscreen wiper   blades.
It
  is   used   for   cleaning   or   replacement   of   the  
b

lades.   It   can   also   be   useful,   in   winter,   to  
d

etach   the   blades   from   the   windscreen.
F
 
A

Windscreen and headlamp
wash
Low screenwash / headlamp
wash fluid level
On vehicle fitted with headlamp washers, the low   level   of   this   fluid   is   indicated   by   gauge   in  
t

he   reservoir   filler   neck   under   the   bonnet.
Checking
  and   topping   up   this   fluid   can   should  
b

e   done   with   the   engine   off.
The
  level   of   this   fluid   should   be   checked  
r

egularly,
 par
ticularly
 d
uring

inter.
For

Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
The anti-slip regulation (also known as traction control)   optimises   traction   to   prevent   skidding  
o

f   the   wheels,   by   acting   on   the   brakes   of   the  
d

riving   wheels   and   on   the   engine.
The electronic stability control acts on the
brake
  of   one   or   more   wheels   and   on   the   engine  
t

o   keep   the   vehicle   on   the   trajectory   required  
b

y   the   driver,   within   the   limits   of   the   laws   of  
p

hysics.
Activation
These systems are activated automatically each   time   the   vehicle   is   started.
They
  come   into   operation   in   the   event   of   a   grip  
o

r
 t
rajectory
 pro
blem.
This
  is   indicated   by   flashing   of   this  
w

arning   lamp   in   the   instrument   panel.
Intelligent traction control
system ("Snow motion")
Deactivation
In extremely severe conditions (deep snow, mud,   ...),   if   you   are   unable   to   move   off,   it   may  
b

e   useful   to   temporarily   deactivate   these  
s

ystems   so   that   the   wheels   can   spin   freely   and  
a

llow   the   vehicle   to   move.
F
 
P
ress   this   button,   located   near   the   steering  
w

heel.
If
  the   indicator   lamp   in   the   button   comes   on,   this
 i

ndicates   that   these   systems   are   deactivated.
Depending
 
on
 
version,
 
your
 
vehicle
 
has
 
a
 
s

ystem
 
to
 
help
 
driving
 
on

intelligent
traction control .
This
 
system
 
detects
 
situations
 
of
 
difficult
 
s

ur face
 
adhesion
 
that
 
could
 
make
 
it
 
difficult
 
to
 
m

ove
 
off
 
or
 
make
 
progress
 
on
 
deep
 
fresh
 
snow
 
o

r

In these situations, the intelligent traction
control
 

limits
 
the

to
 
p

rovide
 
the
 
best
 
traction
 
and
 
trajectory

It  is   recommended   that   the   systems   be

Driving recommendations
Observe the driving regulations and remain vigilant   whatever   the   traffic   conditions.
Pay
  close   attention   to   the   traffic   and   keep   your  
h

ands on the wheel so that you are ready to
react
  at   any   time   to   any   eventuality.
On
  a   long   journey,   a   break   every   two   hours   is  
s

trongly
 re
commended.
In
  difficult   weather,   drive   smoothly,   anticipate  
t

he   need   to   brake   and   increase   the   distance  
f

rom   other   vehicles.
Driving on flooded roads
We strongly advise against driving on flooded roads,   as   this   could   cause   serious   damage  
t

o   the   engine   or   gearbox,   as   well   as   to   the  
e

lectrical   systems   of   your   vehicle.
Important!If you are obliged to drive through water:
-  
c
heck   that   the   depth   of   water   does   not  
e

xceed   15   cm,   taking   account   of   waves  
t

hat   might   be   generated   by   other   users,
-
 
d
eactivate   the   Stop   &   Start   system,
-

d
rive as slowly as possible without
stalling.
  In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-

d
o not stop and do not switch off the
engine. Never
  drive   with   the   parking   brake  
a

pplied   -   Risk   of   overheating   and  
d

amage   to   the   braking   system!
Do
  not   park   or   run   the   engine   when  
s

tationary   in   areas   where   inflammable  
s

ubstances   and   materials   (dry   grass,  
d

ead   leaves...)   might   come   into   contact  
w

ith   the   hot   exhaust   system   -   Risk   of  
f

ire!
Never leave a vehicle unsupervised
with
  the   engine   running.   If   you   have  
t

o   leave   your   vehicle   with   the   engine  
r

unning,   apply   the   parking   brake  
a

nd   put   the   gearbox   into   neutral   or  
p

osition

N or P,
  depending   on   the   type  
o

f   gearbox.
On
  leaving   the   flooded   road,   as   soon   as  
c

ircumstances   allow,   make   several   light   brake  
a

pplications   to   dry   the   brake   discs   and   pads.
If in doubt on the state of your vehicle, contact
a
  CITROËN   dealer   or   a   qualified   workshop.

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

he   axle   and   the   nose   weight   approaches   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude,
thus
 r

educing
 e
ngine
 p
erformance.
 A

bove 1 000 metres,   the   maximum   towed  
l

oad   must   be   reduced   by   10 %   for   every  
1 0

00 metres   of   altitude.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
F  
I
f   the   warning   lamp   and   the  
S

TOP
 
warning   lamp   come   on,  
s

top the vehicle and switch off
the   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  
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   coolant  
t

emperature.

a

 
special   code.   When   the   ignition   is   switched

This
 
electronic   engine   immobiliser   locks   the
