Fresh air intake / Air
recirculation
The intake of fresh air avoids and eliminates misting  of  the  windscreen  and  side  windows.
Recirculation of the interior air isolates the
passenger
 compartment  from  exterior  odours Â
a

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 Â
h
ands on the wheel so that you are ready to
react
 at  any  time  to  any  eventuality.
On
 a  long  journey,  a  break  every  two  hours  is Â
s
trongly
 re
commended.
In
 difficult  weather,  drive  smoothly,  anticipate Â
t
he  need  to  brake  and  increase  the  distance Â
f
rom  other  vehicles.
Driving on flooded
roads
We strongly advise against driving on flooded roads,  as  this  could  cause  serious  damage Â
t
o  the  engine  or  gearbox,  as  well  as  to  the Â
e
lectrical  systems  of  your  vehicle.If
 you  are  obliged  to  drive  through  water:
- Â
c
heck  that  the  depth  of  water  does  not Â
e
xceed  15  cm,  taking  account  of  waves Â
t
hat  might  be  generated  by  other  users,
- Â
d
eactivate  the  Stop  &  Start  system,
-
d
rive as slowly as possible without
stalling.  In  all  cases,  do  not  exceed  6  mph Â
(
10Â km/h),
- d o not stop and do not switch off the
engine.
On
 leaving  the  flooded  road,  as  soon  as Â
c
ircumstances  allow,  make  several  light  brake Â
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.
Important!
Never drive with the parking brake applied  -  Risk  of  overheating  and Â
d
amage  to  the  braking  system!
Do
 not  park  or  run  the  engine  when Â
s
tationary  in  areas  where  inflammable Â
s
ubstances  and  materials  (dry  grass, Â
d
ead  leaves...)  might  come  into Â
c
ontact with  the  hot  exhaust  system  - Â
R
isk  of  fire!
Never leave a vehicle unsupervised
with
 the  engine  running.  If  you  have Â
t
o  leave  your  vehicle  with  the  engine Â
r
unning,  apply  the  parking  brake Â
a
nd  put  the  gearbox  into  neutral  or Â
p
osition
N or P,
 depending  on  the  type Â
o
f  gearbox.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest  items  are  as  close  as  possible  to Â
t
he  axle  and  the  nose  weight  approaches Â
t
he  maximum  permitted  without Â
e
xceeding it.
Air density decreases with altitude, thus
reducing
 engine  per formance.  Above Â
1Â 0
00 metres,  the  maximum  towed  load  must Â
b
e  reduced  by  10 %  for  every  1 000  metres  of Â
al
titude.
For
 more  information  on  weights  (and  the Â
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 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,  the  use  of Â
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 Â
re
commended
 p
ressures.
Lighting
F Check the  electrical  lighting  and  signalling  o
n  the  trailer  and  the  hadlamp  beam  height Â
o
f  your  vehicle.
For
 more  information  on  adjusting  the Â
h
eadlamp  beam  height,  refer  to  the Â
c
orresponding
 s
ection.
The
 rear  parking  sensors  will  be Â
d
eactivated  automatically  if  a  genuine Â
C
ITROËN  towbar  is  used.

Starting
The parking brake must be applied.
F
Â
W

Â
a  manual  gearbox,  place  the  gear Â
l
ever in neutral then depress the clutch
pedal
 f
ully.
F
Â
W

Â
an  electronic  gearbox,  place  the Â
c
ontrol at N  then  press  the  brake  pedal Â
f
i r m l y.
F
Â
I
nsert
 the  key  into  the  ignition  switch;  the Â
s
ystem  recognises  the  code.
F
Â
U
nlock  the  steering  column  by  simultaneously
 t
urning  the  steering  and  the  key.
In
Â
certain  cases,  you  may  have  to  apply Â
m
ore  force  to  the  steering  (wheels  on Â
f
ull
 lock,  for  example).
F
Â
W
ith
Â
a  petrol  engine,  operate  the  starter Â
m
otor
 by  turning  the  key  to  position  3
without
 pressing  the  accelerator  pedal, Â
u
ntil
Â
the  engine  starts.  Once  the  engine  is Â
r
unning,  release  the  key.
Starting-switching off the engine
It has 3 positions:
- position 1 (Stop):
 insert  and  removing Â
the
 key,
-
position 2 (Ignition on) :
 steering  column Â
u
nlocked,  ignition  on,  Diesel  preheating, Â
e
ngine
 r
unning,
-
position 3 (Starting) .
Ignition switch
Switching off the engine leads to a loss o
f  braking  assistance.
Ignition on position (2)
It allows the use of the vehicle's electric equipment  or  portable  devices  to  be  charged.
Once
 the  state  of  charge  of  the  battery  drops Â
t
o  the  reserve  level,  the  system  switches  to Â
e
nergy  economy  mode:  the  power  supply  is Â
c
ut  off  automatically  to  preserve  the  remaining Â
b
attery  charge.
Avoid
 attaching  heavy  objects  to  the Â
k
ey,  which  would  weigh  down  on  its Â
b
lade  in  the  ignition  switch  and  could Â
c
ause  a  malfunction.
It
 could  adversely  affect  the  deployment Â
o
f  the  front  airbag.

F With a  Diesel  engine,  turn  the  key  to  p
osition 2 ,
 ignition  on,  to  operate  the Â

re-heating
 s
ystem.
Wait until this warning lamp goes off in the instrument  panel  then  operate  the  starter m
otor  by  turning  the  key  to  position 3
without
 pressing  the  accelerator  pedal,
 u
ntil  the  engine  starts.  Once  the  engine  is
 r
unning,  release  the  key.
In wintry conditions, the warning lamp can  stay  on  for  a  longer  period.  When Â
t
he  engine  is  hot,  the  warning  lamp Â
d
oes  not  come  on. In
 temperate  conditions,  do  not  leave Â
t
he  engine  at  idle  to  warm  up  but  move Â
o
ff  straight  away  and  drive  at  moderate Â
s
peed.
Never  leave  the  engine  running  in Â
a
n  enclosed  area  without  adequate Â
v
entilation:
 in
ternal
 c
ombustion
 e
ngines  emit  toxic  exhaust  gases, Â
s
uch  as  carbon  monoxide.  Danger  of  i
ntoxication  and  death.
In very severe wintry conditions
(temperatures
 below  -23°C),  to  ensure Â
t
he correct operation and durability of
the
 mechanical  components  of  your Â
v
ehicle,  engine  and  gearbox,  it  is Â
n
ecessary  to  leave  the  engine  running Â
f
or  4  minutes  before  moving  off.
If
 the  engine  does  not  start  straight Â
a
way,  switch  off  the  ignition.  Wait  a  few Â
m
oments  before  operating  the  starter Â
m
otor  again.  If  the  engine  does  not Â
s
tart  after  several  attempts,  do  not  keep Â
t
rying:  you  risk  damaging  the  starter Â
m
otor  or  the  engine.
