Grip control
Special patented traction control system which improves   traction   on   snow,   mud   and   sand.
This
  system,   the   operation   of   which   has   been  
o

ptimised   for   each   situation,   allows   you   to  
m

anoeuvre   in   most   conditions   of   poor   grip  
(

encountered
 d
uring
 t
ouring

Associated
  with   all-seasons   M+S   (Mud   and  
S

now)   205/50   R   17   tyres,   this   system   offers  
a

  compromise   between   safety,   adhesion   and  
t

raction.   These   tyres   work   equally   well   in   winter  
a

nd   summer.
A
  five-position   selector   allows   you   to   choose  
t

he   setting   best   suited   to   the   driving   conditions  
en

countered.
An
  indicator   lamp   associated   with   each   mode  
c

omes   on   to   confirm   your   choice.
A
  specific   and   additional   display   appears  
t

emporarily   in   the   touch   screen   to   confirm   the  
s

election   made   with   the   knob. Every
  time   the   ignition   is   switched   off,  
t

he   system   automatically   resets   to   this  
m

ode.
Differents
  modes   are   provided:
Standard (ESC)
This mode is calibrated for a low level of wheel s
pin,   based   on   the   different   levels   of   grip  
n

ormally   encountered   on   the   road.

Safety

A few driving recommendations
Observe the driving regulations at all times 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  
r

eact   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.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  
s

talling.   In   all   cases,   do   not   exceed   6   mph  
(

10 km/h),
-  d o   not   stop   and   do   not   switch   off   the  e
ngine.
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.
Important!
Never drive with the parking brake applied   -   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  
c

ontact with   the   hot   exhaust   system   -  
R

isk   of   fire!
Never
  leave   a   vehicle   unsupervised  
w

ith   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.

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  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.

Ignition switch
Switching off the engine leads to a loss o
f   braking   assistance.
Ignition on position (2)
It allows the use of the vehicle's electric equipment   or   portable   devices   to   be   charged.
Once
  the   state   of   charge   of   the   battery   drops  
t

o   the   reserve   level,   the   system   switches   to  
e

nergy   economy   mode:   the   power   supply   is  
c

ut   off   automatically   to   preserve   the   remaining  
b

attery   charge.
Avoid
  attaching   heavy   objects   to   the  
k

ey,   which   would   weigh   down   on   its  
b

lade   in   the   ignition   switch   and   could  
c

ause   a   malfunction.
It
  could   adversely   affect   the   deployment  
o

f   the   front   airbag.

Wait until this warning lamp goes off in the instrument   panel   then   operate   the   starter m

otor   by   turning   the   key   to   position 3
without
  pressing   the   accelerator   pedal,
 u

ntil   the   engine   starts.   Once   the   engine   is
 r

unning,   release   the   key.
In wintry conditions, the warning lamp can   stay   on   for   a   longer   period.   When  
t

he   engine   is   hot,   the   warning   lamp  
d

oes   not   come   on. In
  temperate   conditions,   do   not   leave  
t

he   engine   at   idle   to   warm   up   but   move  
o

ff   straight   away   and   drive   at   moderate  
s

peed.
Never   leave   the   engine   running   in  
a

n   enclosed   area   without   adequate  
v

entilation:
 in
ternal
 c
ombustion
 e

ngines   emit   toxic   exhaust   gases,  
s

uch   as   carbon   monoxide.   Danger   of  i
ntoxication   and   death.
In   very   severe   wintry   conditions  
(

temperatures   below   -23°C),   to   ensure  
t

he   correct   operation   and   durability   of  
t

he   mechanical   components   of   your  
v

ehicle,   engine   and   gearbox,   it   is  
n

ecessary   to   leave   the   engine   running  
f

or   4   minutes   before   moving   off.
If
  the   engine   does   not   start   straight  
a

way,   switch   off   the   ignition.   Wait   a   few  
m

oments   before   operating   the   starter  
m

otor   again.   If   the   engine   does   not  
s

tart   after   several   attempts,   do   not   keep  
t

rying:   you   risk   damaging   the   starter  
m

otor   or   the   engine.

Operation
Gear efficiency indicator
System which reduces fuel consumption by advising the driver to change up, on vehicles fitted with a manual gearbox.

ecommendation   according   to   the  
d

riving   conditions   (slope,   load, ...)   and  
t

he   demands   of   the   driver   (power,

Depending
  on   the   driving   situation   and   your  
v

ehicle's   equipment,   the   system   may   advise

On
  certain   Diesel   versions   with   manual
