Airbags
General information
System designed to contribute towards improving   the   safety   of   the   occupants   (with  
t

he   exception   of   the   rear   centre   passenger)  
i

n   the   event   of   violent   collisions.   The   airbags  
s

upplement   the   action   of   the   seat   belts   fitted  
w

ith   force   limiters   (all   except   the   centre   rear  
p

assenger
 b
elt).
If a collision occurs, the electronic detectors
record
  and   analyse   the   front   and   side   impacts  
s

ustained   in   the   impact   detection   zones:
-
 
i
n   the   case   of   a   serious   impact,   the   airbags  
a

re deployed instantly and contribute
towards better protection of the occupants
of
  the   vehicle   (with   the   exception   of   the  
r

ear   centre   passenger);   immediately   after  
t

he   impact,   the   airbags   deflate   rapidly   so  
t

hat   they   do   not   hinder   visibility   or   the   exit  
o

f the occupants,
-
 
i
n   the   case   of   a   minor   or   rear   impact   or   in  
c

ertain   roll-over   conditions,   the   airbags  
m

ay   not   be   deployed;   the   seat   belt  
a

lone   contributes   towards   ensuring   your  
p

rotection   in   these   situations.
Impact detection zones
A. Front  impact   zone.
B. S ide   impact   zone.
The airbags do not operate when the
ignition is switched off.
This
 
equipment
 
will
 
only
 
deploy
 
once.
 
I

f
 
a
 
second
 
impact
 
occurs
 
(during
 
the
 
s

ame
 
or
 
a
 
subsequent
 
accident),
 
the
 
a

irbag
 
will
 
not
 
be
 
deployed
 
again.
Deployment  of   one   or   more   of   the  
a

irbags   is   accompanied   by   a   slight  
e

mission   of   smoke   and   a   noise,   due  
t

o the activation of the pyrotechnic
cartridge
  incorporated   in   the   system.
This
  smoke   is   not   harmful,   but   sensitive  
i

ndividuals   may   experience   slight  
ir

ritation.
The noise of detonation related to the
deployment
  of   one   or   more   airbags   may  
r

esult   in   a   slight   loss   of   hearing   for   a  
s

hort   time.

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.

t

he   engine   can   be   started.
The presence of the "Keyless Entry
and

Before each use
Check that the towball is correctly fitted by verifying the following points:
-  t he   towball   is   correctly   locked   in   place   (position   A),
-
 
t
he   security   key   lock   is   on   and   the   key   removed;   the   locking   wheel   can   no   longer   be  
ope

rated,
-
 
t
he   towball   must   no   longer   move   at   all   in   its   carrier;   try   to   shake   it   by   hand.
During use
Never unlock the device when a trailer or load carrier is fitted to the towball.
N ever   exceed   the   maximum   authorised   weight   for   the   vehicle   plus   trailer   (Gross   Train  
W

eight   -   GTW).
Before
  driving,   check   the   adjustment   of   the   headlamp   beam   height.
For
  more   information   on   adjusting   the   headlamps,   refer   to   the   corresponding   section.
After use
For journeys made without a trailer or load carrier, the trailer harness socket must be folded away,   the   towball   removed   and    the   blanking   plug   inserted   in   the   carrier.   This   measure  
a

pplies   particularly   if   the   towball   could   hinder   visibility   of   the   number   plate   or   lighting.
