Ventilation
Air intake
The air circulating in the passenger compartment is   filtered   and   originates   either   from   the   outside   via t

he   grille   located   at   the   base   of   the   windscreen   or
 f

rom   the   inside   in   air   recirculation   mode.
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).
The
  temperature   control   enables   you   to   obtain  
t

he   level   of   comfort   required   by   mixing   the   air   of  
t

he   various   circuits.
The
  air   distribution   control   enables   you   to  
d

iffuse   the   air   in   the   passenger   compartment  
c

ombining   several   air   vents.
The air flow control enables you to increase or
reduce
  the   speed   of   the   ventilation   blower.
Control panel
The controls of this system are grouped together   on   control   panel   A on the centre
console.
  Depending   on   the   model,   the  
f

Starting using another
battery
When your vehicle's battery is discharged, the e ngine   can   be   started   using   a   slave   battery  
(

external   or   on   another   vehicle)   and   jump   lead

a
  few   minutes.
F
 
O
perate   the   starter   on   the   broken   down  
v

ehicle   and   let   the   engine   run.
If
  the   engine   does   not   start   straight   away,  
s

witch   off   the   ignition   and   wait   a   few   moments  
b

efore   trying   again.
F
 
W
ait   until   the   engine   returns   to   idle   then  
d

r

everse
 o
rder.
F
 
R
efit   the   plastic   cover   to   the   (+)   terminal,   if  
y

our   vehicle   has   one.
F
 
A
llow   the   engine   to   run   for   at   least  
3

0 minutes,   by   driving   or   with   the   vehicle  
s

tationary, so that the battery reaches an
adequate
  state   of   charge.

Towing with the gT RACIn g version
Your vehicle cannot be fitted with a t
owbar.   The   space   occupied   by   the  
s

port   diffuser   prevents   this.
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  
t

he   engine   as   soon   as   possible.
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  v
ehicle   and   of   the   trailer,   observing   the  
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.

it
 
is
 
r

ecommended
 
that
 
exposure
 
to
 
water

Checks

Checking levels
Check all of these levels regularly, in line with the manufacturer's service schedule. Top them up if necessary, unless other wise indicated.
I f   a   level   drops   significantly,   have   the   corresponding   system   checked   by   a   CITROËN   dealer   or   a   qualified   workshop.
Engine oil level
It is normal to top up the oil level between two   services   (or   oil   changes).   CITROËN  
r

ecommends   that   you   check   the   level,   and   top  
u

p   if   necessary,   every   3   000   miles   (5   000   kms).
The
  check   is   carried   out   either   when  
t

he   ignition   is   switched   on   using   the  
o

il   level   indicator   in   the   instrument  
p

anel   for   vehicles   so   equipped,   or  
u

sing   the   dipstick.
To   ensure   that   the   reading   is   correct,  
y

our   vehicle   must   be   parked   on   a   level  
s

ur face   with   the   engine   having   been   off  
f

or   more   than   30   minutes.
Take   care   when   working   under   the  
b

onnet,   as   certain   areas   of   the   engine  
m

ay   be   extremely   hot   (risk   of   burns)  
a

nd   the   cooling   fan   could   start   at   any  
t

ime   (even   with   the   ignition   off).
Checking using the dipstick
A = MA X
B   =   MIN If
  you   find   that   the   level   is   above   the   A   mark   or

correct   level   is   between   the   marks   A
and
 
B
.
Oil grade
Before topping-up the oil or changing the oil, c
heck   that   the   oil   is   the   correct   grade   for   your  
e

ngine   and   conforms   to   the   manufacturer's  
r

ecommendations.

Fluid specification
The coolant must conform to the manufacturer's r ecommendations.
Coolant level
The coolant level should be close to   the   "MA X"   mark   but   should   never  
e

xceed   it.
In
 
addition,   as   the   cooling   system   is  
p

ressurised,   wait   at   least   one   hour   after  
s

witching
 
off   the   engine   before   carrying   out   any  
wo

rk.
To
 
avoid
 
any   risk   of   scalding,   unscrew   the   cap  
b

y
 
two
 
turns   to   allow   the   pressure   to   drop.  
W

hen
 
the
  pressure   has   dropped,   remove   the  
c

ap
 
and
 
top   up   the   level.
When
 
the
  engine   is   warm,   the   temperature   of  
t

he
 
coolant   is   regulated   by   the   fan.
The cooling fan may star t after
switching off the engine: take care
with articles and clothing that might
be caught by the fan blades.
