Warning lamps
When the engine is running or the vehicle is being driven, illumination of one of the following warning lamps indicates a fault which requires action on the   part   of   the   driver.
Any
  fault   resulting   in   the   illumination   of   a   warning   lamp   must   be   investigated   further   using   the   associated   message.
If
  you   encounter   any   problems,   contact   a   CITROËN   dealer   or   a   qualified   workshop.

river:
-

Air conditioning On/Off
The air conditioning is designed to operate e
fficiently in all seasons, with the windows
closed. The
  intake   of   exterior   air   avoids   and   eliminates  m
isting   of   the   windscreen   and   side   windows.

When towing
Distribution of loads
F Distribute the load in the trailer so that the heaviest   items   are   as   close   as   possible   to  
t

he   axle   and   the   nose   weight   approaches  
t

he   maximum   permitted   without  
e

xceeding it.
Air density decreases with altitude, thus
reducing
  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.
For
  more   information   on   weights   (and   the  
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  
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
the
  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   hadlamp   beam   height  
o

f   your   vehicle.
For
  more   information   on   adjusting   the  
h

eadlamp   beam   height,   refer   to   the  
c

orresponding
 s
ection.

Bonnet
F Open  the   left   hand   front   door. The location of the interior bonnet
release
  lever   prevents   opening   of   the  
b

onnet when the left hand front door
is   shut.
When   the   engine   is   hot,   handle   the  
e

xterior   safety   catch   and   the   stay   with  
c

are   (risk   of   burns),   using   the   protected  
a

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

o   damage   the   safety   catch.
F  
L
ift   the   safety   catch   and   raise   the   bonnet.F
 U nclip   the   stay   from   its   housing   and   place  i
t in the support slot to hold the bonnet
open.
Opening
F Pull   the   release   lever,   located   at   the   bottom  o
f   the   door   aperture,   towards   you.
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.
Do not open the bonnet under very
windy
 c

onditions.
Closing
F Take  the   stay   out   of   its   support   slot.
F  C lip   the   stay   back   into   its   housing.
F

L
ower the bonnet and release it at the end
of
  its   travel.
F
 
P
ull   on   the   bonnet   to   check   that   it   has  
l

atched   correctly. Because of the presence of electrical
equipment
  under   the   bonnet,   it   is  
r

ecommended   that   exposure   to   water  
(

rain,   washing, ...)   be   limited.
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

Checking levels
Take care when working under the bonnet,   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).
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
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.
If you find that the level is above the A
  mark   or  
belo

w the B   mark,   do not star t the engine.
-

I
f the level is above the MAX
 
mark   (risk  
o

f   damage   to   the   engine),   contact   a  
C

ITROËN   dealer   or   a   qualified   workshop.
-

I
f the level is below the MIN
 
mark,   you  
m

ust   top   up   the   engine   oil.
A = MA X
B = MIN
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.
It
  is   normal   to   top   up   the   oil   level   between  
t

wo   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
  location   of   the   dipstick   is   shown   in   the

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

r

ecommendations.

Coolant level
The coolant level should be close
to  the   "MA X"   mark   but   should   never  
e

xceed   it.

at
 
least   one   hour   after   switching   off   the

ngine
 
before   carrying   out   any   work.
To
 
avoid
 
any   risk   of   scalding,   unscrew   the   cap   by
 t

wo
 
turns
 
to   allow   the   pressure   to   drop.   When   the
 p

ressure
 
has   dropped,   remove   the   cap   and   top
 u

p
 
the
 
level.
Changing the coolant
The coolant does not have to be replaced at routine services.
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. When   the   engine   is   warm,   the   temperature   of  
t

he   coolant   is   regulated   by   the   fan.
Fluid specification
The coolant must conform to the ma
nufacturer's r ecommendations.
