Driving advice
Your vehicle is designed principally to drive   on   tarmac   roads   but   it   allows   you  
t

o drive on other less passable terrain
occasionally.
However,
  it   does   not   permit   off-road  
d

riving   such   as:
-
 
c
rossing   and   driving   on   terrain  
w

hich   could   damage   the   underbody  
o

r   strip   away   components   (fuel  
p

ipe,   fuel   cooler...)   due   to   obstacles  
o

r stones in particular,
-
 
d
riving   on   terrain   with   steep  
g

radients   and   poor   grip,
-
 
c
rossing   a   stream.All terrain (mud, damp grass, ...)
This mode, when moving off, allows considerable spin on the wheel with the least
grip
  to   optimise   clearing   of   the   mud   and   regain  
g

rip.   At   the   same   time,   the   wheel   with   the   most  
g

rip   is   controlled   in   such   a   way   as   to   pass   as  
m

uch   torque   as   possible.
When
  moving,   the   system   optimises   wheel   spin  
t

o   respond   to   the   driver's   requirements   as   fully  
a

s   possible.
(mode
  active   up   to   50   mph   (80   km/h))
F
 
P
lace   the   dial   in   this   position.
Sand
This mode allows little spin on the two driving wheels   at   the   same   time   to   allow   the   vehicle   to  
m

ove   for ward   and   limit   the   risks   of   getting   stuck  
i

n   the   sand.
(mode
  active   up   to   75   mph   (120   km/h))
F
 
P
lace   the   dial   in   this   position.
Do
  not   use   the   other   modes   on   sand   as   the  
v

ehicle   may   become   stuck. You can deactivate certain functions of the
ESC
  (ASR   and   DSC)   by   turning   the   dial   to   the  
"
O
FF
"   position.
These   functions   are   reactivated   automatically  
f

rom   30   mph   (50   km/h)   or   every   time   the  
i

gnition   is   switched   back   on.

Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning  and   force   limiting   system.
This
  system   improves   safety   in   the   front  
s

eats   in   the   event   of   a   front   or   side   impact.  
D

epending   on   the   severity   of   the   impact,   the  
p

retensioning   system   instantly   tightens   the   seat  
b

elts   against   the   body   of   the   occupants.
The
  pretensioning   seat   belts   are   active   when  
t

he   ignition   is   on.
The
  force   limiter   reduces   the   pressure   of   the  
s

eat belt on the chest of the occupant, so
improving
  their   protection.Fastening

The driver must ensure that passengers use the seat belts correctly and that they are all
fastened
  before   setting   off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do
  not   interchange   the   seat   belt   buckles   as  
t

hey   will   not   fulfil   their   role   fully.
The seat belts are fitted with an inertia reel
permitting
  automatic   adjustment   of   the  
l

ength   of   the   strap   to   your   size.   The   seat   belt  
i

s   stowed   automatically   when   not   in   use.
Before and after use, ensure that the seat
belt
  is   reeled   in   correctly.
The
  lower   part   of   the   strap   must   be  
p

ositioned   as   low   as   possible   on   the   pelvis.
The
  upper   part   must   be   positioned   in   the  
h

ollow   of   the   shoulder.
The
  inertia   reels   are   fitted   with   an   automatic  
l

ocking   device   which   comes   into   operation   in  
t

he   event   of   a   collision,   emergency   braking  
o

r   if   the   vehicle   rolls   over.   You   can   release  
t

he   device   by   pulling   the   strap   firmly   and  
t

hen   releasing   it   so   that   it   reels   in   slightly.Recommendations for
children
Use a suitable child seat if the passenger is less than 12 years old or shorter than one
and
  a   half   metres.
Never
  use   the   same   seat   belt   to   secure   more  
t

han   one   person.
Never
  allow   a   child   to   travel   on   your   lap.
For
  more   information   on   child   seats,   refer   to  
t

he   corresponding   section.
In
 
order
 
to
 
be
 
effective,
 
a
 
seat
 
belt
 
must:

In the event of an impact
Depending on the nature and
seriousness of the impact , the
pretensioning
  device   may   be   deployed  
b

efore   and   independently   of   the   airbags.  
D

eployment   of   the   pretensioners   is  
a

ccompanied   by   a   slight   discharge   of  
h

armless   smoke   and   a   noise,   due   to   the  
a

ctivation   of   the   pyrotechnic   cartridge  
i

ncorporated   in   the   system.
In
  all   cases,   the   airbag   warning   lamp  
comes
  on.
Following
  an   impact,   have   the   seat   belts  
s

ystem   checked,   and   if   necessary   replaced,  
b

y   a   CITROËN   dealer   or   a   qualified  
w

orkshop.
In accordance with current safety
regulations,
 
for
 
all
 
repairs
 
on
 
your
 
vehicle's
 
s

eat
 
belts,
 
go
 
to
 
a
 
qualified
 
workshop
 
with
 t
he
 
skills
 
and
 
equipment
 
needed,
 
which
 
a
 C
ITROËN
 
dealer
 
is
 
able
 
to
 
provide.
Have
 
your
 
seat
 
belts
 
checked
 
regularly
 
by
 
a

 
CITROËN
 
dealer
 
or
 
a
 
qualified
 
workshop,
 
p

articularly
 
if
 
the
 
straps
 
show
 
signs
 
of
 
d

amage.
Clean the seat belt straps with soapy
water
 
or
 
a
 
textile
 
cleaning
 
product,
 
sold
 
by

dealers.
After

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. 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.
