Ventilation
Air intake
The air circulating in the passenger compartment   is   filtered   and   originates   either

Air treatment
The incoming air follows various routes depending   on   the   controls   selected   by   the  
d

river:
-
 
d
irect   arrival   in   the   passenger  
c

ompartment   (air   intake),
-

When

on
 
a
 
steep
 
gradient
 
in
 
high
 
temperatures,
 
switching
 
off
 
the

ir
 
conditioning
 
increases
 
the
 
available
 
engine
 
power
 
and
 
so
 
improves
 
the
 
towing
 
ability. The
  condensation   created   by   the   air  
c

onditioning   results   in   a   discharge

f   water   under   the   vehicle   which   is  
p

er fectly   normal.
If   after   an   extended   stop   in   sunshine,  
t

he   interior   temperature   is   very  
h

igh,   first   ventilate   the   passenger  
c

ompartment   for   a   few   moments.

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.
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  
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. 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  
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.
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.

Ignition switch
Avoid attaching heavy objects to the key,   which   would   weigh   down   on   its

Starting the engine
F With  a   petrol   engine,   operate   the   starter  m
otor   by   turning   the   key   to   position   3

u

ntil   the   engine   starts.   Once   the   engine   is

Wait   until   this   warning   lamp   goes   off  
i

n   the   instrument   panel   then   operate  
t

he   starter   motor   by   turning   the   key  
t

o position 3   without   pressing   the  
a

ccelerator   pedal,   until   the   engine  
s

tarts.   Once   the   engine   is   running,  
r

elease   the   key.
If   the   engine   does   not   start   straight  
a

way,   switch   off   the   ignition.   Wait   a  
f

ew   moments   before   operating   the  
s

tarter   motor   again.   If   the   engine   does  
n

ot   start   after   several   attempts,   do   not  
k

eep   trying:   you   risk   damaging   the  
s

tarter   motor   or   the   engine.   Contact  
a

  CITROËN   dealer   or   a   qualified  
w

orkshop.Never
  leave   the   engine   running   in  
a

v

entilation:

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.
In
  certain   cases,   you   may   have   to   apply  
m

ore   force   to   the   steering   (wheels   on  
f

ull   lock,   for   example).
In   wintry   conditions,   the   warning   lamp  
c

an   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

s

peed.

F If  the   warning   lamp   and   the  S
TOP  warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

Braking
Towing a trailer increases the braking distance.
T o   avoid   overheating   of   the   brakes   on   a   long  
m

ountain   type   of   descent,   the   use   of   engine  
b

raking   is   recommended.
Ty r e s
F Check   the   tyre   pressures   of   the  
towing   vehicle   and   of   the   trailer,   observing  
t

he
 re
commended
 p
ressures.
Lighting
F Check  the   electrical   lighting   and   signalling  o
n   the   trailer.
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   
c
oolant  
t

emperature.
