Lost keys
Go to a CITROËN dealer with the vehicle's registration document, your personal identification   documents   and   if   possible   the   key   code   label.
The
  CITROËN   dealer   will   be   able   to   look   up   the   key   code   and   the   transponder   code  
r

equired   to   order   a   new   key.
Remote control
The high frequency remote control is a sensitive system; do not operate it while it is in your pocket   as   there   is   a   possibility   that   it   may   unlock   the   vehicle,   without   you   being   aware   of   it.
Do
  not   repeatedly   press   the   buttons   of   your   remote   control   out   of   range   and   out   of   sight   of  
y

our   vehicle.   You   run   the   risk   of   stopping   it   from   working   and   the   remote   control   would   have  
t

o   be   reinitialised.
No
  remote   control   can   operate   when   the   key   is   in   the   ignition   switch,   even   when   the   ignition  
i

s   switched   off,   except   for   reinitialisation.
Locking the vehicle
Driving with the doors locked may make access to the passenger compartment by the emergency   services   more   difficult   in   an   emergency.
As
  a   safety   precaution,   never   leave   children   alone   in   the   vehicle,   except   for   a   very   short   period.
In
  all   cases,   it   is   essential   to   remove   the   key   from   the   ignition   switch   when   leaving   the  
v

ehicle.
Anti-theft protection
Do not make any modifications to the electronic engine immobiliser system; this could c ause m alfunctions.
When purchasing a second-hand vehicle
Have the pairing of all of the keys in your possession checked by a CITROËN dealer, to ensure   that   only   your   keys   can   be   used   to   open   and   start   the   vehicle.

which
 
prevents
 
it
 
from
 
lowering;
 t

his   is   a   safety   device   in   case   of   impact.
The adjustment is correct when the
upper edge of the head restraint is
level with the top of the head.
Never drive with the head restraints

In order for these systems to be fully effective, follow the operation and maintenance guidelines belo w:
F
 
T
o   obtain   an   even   air   distribution,   take   care   not   to   obstruct   the   exterior   air   intake   grilles  
l

ocated at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as
  the   air   extractor   located   in   the   boot.
F
 
D
o   not   cover   the   sunshine   sensor,   located   on   the   dashboard;   this   is   used   for   regulation  
o

f   the   air   conditioning   system.
F
 
O
perate   the   air   conditioning   system   for   at   least   5   to   10   minutes,   once   or   twice   a   month  
t

o   keep   it   in   per fect   working   order.
F
 
E
nsure   that   the   passenger   compartment   filter   is   in   good   condition   and   have   the   filter  
e

lements   replaced   regularly.
  W

e   recommend   the   use   of   a   combined   passenger   compartment   filter.   Thanks   to   its  
s

pecial active additive, it contributes to the purification of the air breathed by the
occupants
  and   the   cleanliness   of   the   passenger   compartment   (reduction   of   allergic  
s

ymptoms,   bad   odours   and   greasy   deposits).
F
 
T
o   ensure   correct   operation   of   the   air   conditioning   system,   you   are   also   advised   to   have  
i

t   checked   regularly   as   recommended   in   the   maintenance   and   warranty   guide.
F
 
I
f   the   system   does   not   produce   cold   air,   switch   it   off   and   contact   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Recommendations for ventilation and air conditioning
If after an extended stop in sunshine, the  i nterior  t emperature  i s  v ery  h igh,  f irst  
v

entilate   the   passenger   compartment   for  
a

  few   moments.
Put
  the   air   flow   control   at   a   setting   high  
e

nough   to   quickly   change   the   air   in   the  
p

assenger
 c
ompartment.
The
  air   conditioning   system   does   not  
c

ontain chlorine and does not present
any
  danger   to   the   ozone   layer.
The condensation created by the air
conditioning
  results   in   a   discharge  
o

f water under the vehicle which is
per fectly
  normal.
When
 
towing
 
the
 
maximum
 
load
 
on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the
 
a

ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability.
Stop & Start
The heating and air conditioning s ystems   only   work   when   the   engine   is  
r

unning.
To
  maintain   a   comfortable   temperature  
i

n   the   passenger   compartment,   you   can  
t

emporarily   deactivate   the   Stop   &   Start  
s

ystem.

Dynamic stability control
(DSC) and anti-slip regulation
(ASR)The DSC system offers exceptional safety   in   normal   driving,   but   this   should  
n

ot   encourage   the   driver   to   take   extra  
r

isks   or   drive   at   high   speed.

egarding   the   wheels   (tyres   and   rims),  
t

he   braking   components,   the   electronic  
c

omponents   and   the   CITROËN  
a

ssembly   and   operation   procedures.
After
  an   impact,   have   the   system  
c

hecked   by   a   CITROËN   dealer   or   a  
q

ualified
 w
orkshop.
Activation
These systems are activated automatically each   time   the   vehicle   is   started.
As
  soon   as   they   detect   a   problem   of   grip   or  
t

rajectory,   these   systems   act   on   the   operation   if  
t

he   engine   and   brakes.
Deactivation
In exceptional conditions (starting a vehicle which   is   bogged   down,   stuck   in   snow,   on   soft  
g

round...),   it   may   be   advisable   to   deactivate  
t

he   DSC   system,   so   that   the   wheels   can   move  
f

reely   and   regain   grip.
This
 
is
 
indicated
 
by
 
flashing
 
of
 
this
 
w

arning
 
lamp
 
in
 
the
 
instrument
 
panel.

onger   acts   on   the   operation   of   the   engine.
Reactivation
The system is reactivated automatically each time   the   ignition   is   switched   back   on   or   from  
3

0 mph   (50   km/h).F

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  
t

he   maximum   permitted   without  
e

xceeding it.
Air density decreases with altitude, thus
reducing
  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
to
  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
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
