Electronic engine immobiliser
The key contains an electronic chip which has a
  special   code.   When   the   ignition   is   switched  
o
n,   this   code   must   be   recognised   in   order   for  
s
tarting   to   be   possible.
This

a
fter   the   ignition   is   switched   off   and   prevents  
s
tarting   of   the   engine   by   anyone   who   does   not  
h

informed
  by   illumination   of   this

Driving advice
Distribution of loads
F  distribute the load in the trailer so that the heaviest   items   are   as   close   as  
p
ossible   to   the   axle   and   the   nose   weight  
a
pproaches   the   maximum   permitted  
w
ithout   exceeding   it.
ai
r 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.
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   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.
Refer to the "Technical data" section for details 
of
 
the
 
weights
 
and
 
towed
 
loads
 
which
 
apply
 
to
 
y
our
 
vehicle.
When
 
not
 
towing
 
a
 
trailer,
 
remove
 
the
 
q
uickly-detachable
 
tow
 
ball
 
before
 
d
riving. The
  rear   parking   sensors   will   be  
d
eactivated   automatically   if   a   genuine

Brake wear depends on the style of   driving,   particularly   in   the   case  
o

distances.

Brake pads
For information on checking brake disc wear, contact a CITRoËn  dealer

In
  order   to   optimise   the   operation   of

ffers   very   specific   products.
After
  washing   the   vehicle,   dampness,

Parking brake
If excessive travel or a loss of effectiveness   of   this   system   is

Checking
  this   system   must   be   done   by   a  
C
