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

rom   the   outside   via   the   grille   located   at   the  
b

ase   of   the   windscreen   or   from   the   inside   in   air

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),
-
 
p
assage   through   a   heating   circuit   (heating),
-
 
p
assage   through   a   cooling   circuit   (air  
c

onditioning).

Air conditioning On/Off
The air conditioning is designed to operate e
fficiently   in   all   seasons,   with   the   windows  
c

losed.
It
  allows   you:
-
 
i
n   summer,   to   lower   the   temperature,
-
 
i
n   winter,   above   3   °C,   to   improve   demisting.
Avoid
  prolonged   operation   of   the   air  
r

ecirculation   function   (risk   of   misting  
a

nd   of   deterioration   of   the   air   quality).
When
  the   indicator   lamp   is   off,   the   intake   of  
e

xterior   air   is   active.

The
  intake   of   exterior   air   avoids   misting   of   the  w
indscreen   and   side   windows.
Air
  recirculation   prevents   exterior   odours  
a

c

ompartment.
This
  function   also   allows   faster   heating

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   the
 m

aximum   permitted   without   exceeding   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.
Side wind
F Take   into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   Weights
, refer
to   the   corresponding   section.
The   rear   parking   sensors   will   be  
d

eactivated   automatically   to   avoid   the  
a

udible   signal   if   a   genuine   CITROËN  
t

owbar   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. F

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   headlamp   beam  
h

eight   of   your   vehicle.
For
  more   information   on   Adjusting the
headlamp beam height , refer to the

Opening
F Pull  the   release   lever,   located   at   the   bottom  o
f   the   door   aperture,   towards   you. Before
  doing   anything   under   the  
b

onnet, switch off the Stop & Start
system
  to   avoid   any   risk   of   injury  
r

esulting   from   an   automatic   change   to  
S

TART   mode.
The cooling fan may star t after switching off the engine: take care with ar ticles and
clothing that might be caught by the fan blades. Do
  not   open   the   bonnet   under   very  
wi

ndy
 c
onditions.
The location of the interior bonnet
release   lever   prevents   opening   of   the  
b

onnet   when   the   left   hand   front   door  
i

s   shut.
When   the   engine   is   hot,   handle   the  
e

xterior   safety   catch   and   the   stay   with

are   (risk   of   burns),   using   the   protected  
a

rea.
When   the   bonnet   is   open,   take   care   not  
t

o   damage   the   safety   catch.
Because   of   the   presence   of   electrical   equipment   under   the   bonnet,   it   is   recommended   that  
e

xposure   to   water   (rain,   washing,   ...)   be   limited.
Closing
F Take  the   stay   out   of   its   support   slot.

Checking levels
Take care when working under the bonnet, as certain areas of the engine may be extremely hot (risk of burns) and the cooling fan could start at any   time   (even   with   the   ignition   off).
Engine oil level
The check is carried out either when the   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.Checking using the dipstick
The location of the dipstick is shown in the corresponding   underbonnet   layout   view.

n

on-fluffy   cloth.
F
 
R
efit   the   dipstick   and   push   fully   down,   then  
p

ull   it   out   again   to   make   the   visual   check:

top-
up
 
if
 
necessary,
 
every
 
3

Check
 
all
 
of
 
these
 
levels
 
regularly,
 
in
 
line
 
with
 
the
 
manufacturer's   service   schedule.   Top   them   up   if   necessary,   unless   other wise   indicated.
If
 
a
 
level
 
drops
 
significantly,
 
have
 
the
 
corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
To
 
ensure
