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 Â
d
river:
-
Â
d
irect  arrival  in  the  passenger Â
c
ompartment  (air  intake),
-
Â
p
assage  through  a  heating  circuit  (heating),
-
Â
p
assage  through  a  cooling  circuit  (air Â
c
onditioning).
The
 temperature  control  enables  you  to  obtain Â
t
he  level  of  comfort  required  by  mixing  the  air  of Â
t
he  various  circuits.
The air distribution control enables you to
diffuse
 the  air  in  the  passenger  compartment Â
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 Â
f
unctions  offered  are:
-
Â
t
he  level  of  comfort  required,
-
a
ir flow,
-
a

Towing with the RACIng version
Your vehicle cannot be fitted with a
towbar.
 The  space  occupied  by  the Â
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 Â
c
apacity  is  not  dependent  on  the  engine  speed.
F
Â
T
o  lower  the  engine  speed,  reduce  your Â
s
peed.
The
 maximum  towed  load  on  a  long  incline Â
d
epends  on  the  gradient  and  the  ambient Â
t
emperature.
In
 all  cases,  keep  a  check  on  the  coolant Â
t
emperature. F
Â
I
f  the  warning  lamp  and  the Â
S
TOP
Â
warning  lamp  come  on, Â
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  on  a  long Â
m
ountain  type  of  descent,  the  use  of  engine Â
b
raking  is  recommended.
Ty r e s
F Check  the  tyre  pressures  of  the  towing  v
ehicle  and  of  the  trailer,  observing  the Â
re
commended
 p
ressures.
Lighting
F Check the  electrical  lighting  and  signalling  o
n  the  trailer.
The
 rear  parking  sensors  will  be Â
d
eactivated  automatically  if  a  genuine Â
C
ITROËN  towbar  is  used.
Practical information
Page 244 of 458

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 Â
r
ecommends  that  you  check  the  level,  and  top Â
u
p  if  necessary,  every  3  000  miles  (5  000  kms).
The
 check  is  carried  out  either  when Â
t
he  ignition  is  switched  on  using  the Â
o
il  level  indicator  in  the  instrument Â
p
anel  for  vehicles  so  equipped,  or Â
u
sing  the  dipstick.
To  ensure  that  the  reading  is  correct, Â
y
our  vehicle  must  be  parked  on  a  level Â
s
ur face  with  the  engine  having  been  off Â
f
or  more  than  30  minutes.
Take  care  when  working  under  the Â
b
onnet,  as  certain  areas  of  the  engine Â
m
ay  be  extremely  hot  (risk  of  burns) Â
a
nd  the  cooling  fan  could  start  at  any Â
t
ime  (even  with  the  ignition  off).
Checking using the dipstick
AÂ =Â MA X
B Â = Â MIN If you find that the level is above the A
 mark  or Â
belo
w the B Â mark, Â do not star t the engine
.
-
I
f the level is above the MAX
Â
mark  (risk Â
o
f  damage  to  the  engine),  contact  a Â
C
ITROËN  dealer  or  a  qualified  workshop.
-
I
f the level is below the MI n
 mark,  you Â
m
ust  top  up  the  engine  oil.
Refer
Â
to
Â
the
Â
"Petrol  engine"  or  "Diesel  engine" Â
s
ection
Â
for
Â
the  location  of  the  dipstick  in  the Â
e
ngine
Â
compartment  of  your  vehicle.
F
Â
T
ake
Â
the
 dipstick  by  its  coloured  grip  and Â
r
emove
Â
it  completely.
F
Â
W
ipe
Â
the
 end  of  the  dipstick  using  a  clean Â
n
on-fluffy  cloth.
F
Â
R
efit
Â
the
 dipstick  and  push  fully  down,  then Â
p
ull
Â
it
Â
out  again  to  make  the  visual  check: Â
t
he
Â
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 Â
e
ngine  and  conforms  to  the  manufacturer's Â
r
ecommendations.
Page 246 of 458

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 Â
e
xceed  it.
In
Â
addition,  as  the  cooling  system  is Â
p
ressurised, wait at least one hour after
switching
Â
off  the  engine  before  carrying  out  any Â
wo
rk.
To
Â
avoid
Â
any  risk  of  scalding,  unscrew  the  cap Â
b
y
Â
two
Â
turns  to  allow  the  pressure  to  drop. Â
W
hen
Â
the
 pressure  has  dropped,  remove  the Â
c
ap
Â
and
Â
top  up  the  level.
When
Â
the
 engine  is  warm,  the  temperature  of Â
t
he
Â
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.
Screenwash fluid level
Fluid specification
For optimum cleaning and to avoid freezing, t his  fluid  must  not  be  topped  up  or  replaced Â
w
ith  plain  water.
In
Â
w
intry Â
c
onditions, Â
i
t Â
i
s Â
r

ou Â
u
se  an  ethyl  alcohol  or  methanol  based  fluid.
Top
 up  the  level  when  necessary.
