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   the
 m

aximum   permitted   without   exceeding   it.
Air density decreases with altitude,
thus
 r

educing
 e
ngine
 p
erformance.
 A

bove 1 000 metres,   the   maximum   towed  
l

oad   must   be   reduced   by   10 %   for   every  
1 0

00 metres   of   altitude.
Side wind
F Take  into   account   the   increased   sensitivity  t
o   side   wind.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   the   corresponding   section.
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.
The
  rear   parking   sensors   will   be  
d

eactivated   automatically   if   a   genuine  
C

ITROËN   towbar   is   used.
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.

Tyre under-inflation detection
System which automatically checks the p
ressures   of   the   tyres   while   driving.
The
  system   continuously   monitors   the  
p

ressures of the four tyres, as soon as the
vehicle
  is   moving.
A pressure sensor is located in the valve of
each
  tyre   (except   the   spare   wheel).
The
  system   triggers   an   alert   if   a   drop   in  
p

ressure   is   detected   in   one   or   more   tyres.
The
  tyre   under-inflation   detection   system   is   an  
a

id   to   driving   which   does   not   replace   the   need  
f

or   vigilance   on   the   part   of   the   driver.This
  system   does   not   avoid   the   need  
t

o   check   the   tyre   pressures   regularly  
(

including   the   spare   wheel)   and   before  
a

  long   journey.
Driving   with   under-inflated   tyres  
a

dversely   affects   road   holding,  
e

xtends   braking   distances   and   causes  
p

remature   tyre   wear,   particularly   under  a
rduous   conditions   (vehicle   loaded,  h
igh   speed,   long   journey).The tyre pressures for your vehicle can
be
  found   on   the   tyre   pressure   label.
The   tyre   pressures   must   be   checked  
w

hen   the   tyres   cold   (vehicle   stopped  
f

or   1   hour   or   after   driving   for   less   then  
6

  miles   (10   km)   at   moderate   speed).  
O

ther wise,   add   0.3   bar   to   the   values  
i

ndicated   on   the   label.
For m ore i nformation o n id entification m
arkings,   including   the   tyre   pressure  
l

abel,   refer   to   the   corresponding  
s

ection.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Operating fault
The alert is given by the fixed illumination   of   this   warning   lamp,

p

ressures   at   the   time,   drive   carefully   at

or
F
I
n the event of a puncture, use the
temporary   puncture   repair   kit   or   the   spare  
w

heel   (according   to   equipment).
Go   to   a   CITROËN   dealer   or   a   qualified  w
orkshop to   have   the   system   checked   or,  
f

ollowing   the   repair   of   a   puncture,   to   have   the  
o

riginal   wheel,   equipped   with   a   sensor,   refitted.
Any
  tyre   repair   or   replacement   on   a   wheel  
f

itted   with   this   system   must   be   carried   out   by   a  
C

ITROËN   dealer   or   a   qualified   workshop.
If
  after   changing   a   tyre,   a   wheel   is   not   detected  
b

y   your   vehicle   (fitting   snow   tyres   for   example),  
y

ou   must   have   the   system   reinitialised   by   a  
C

ITROËN   dealer   or   a   qualified   workshop.
The loss of pressure detected does not
always
  lead   to   visible   deformation   of  
t

he   tyre.
Do
  not   rely   on   just   a   visual   check.This alert is also displayed when one or
more
  wheels   is   not   fitted   with   a   sensor  
(

for   example,   a   space-saver   or   steel  
spar

e
 w
heel).
The   alert   is   maintained   until   the   tyre   or  t
yres concerned is reinflated, repaired
or   replaced.
The
  spare   wheel   (space-saver   type   or   a  
s

teel   rim)   does   not   have   a   sensor.

Activation
Deactivation
DetectionOperating fault
System which detects the involuntary crossing o
f   longitudinal   traffic   lane   markings   on   the  
g

round   (solid   or   broken   line).
Sensors,
  fitted   below   the   front   bumper,   trigger  
a

  warning   if   the   vehicle   drifts   over   a   lane  
m

arking   (speed   higher   than   50   mph   (80   km/h)).
This
  system   is   particularly   useful   on   motor ways  
a

nd   main   roads. In
  the   event   of   a   malfunction,   the  
s

ervice   warning   lamp   comes   on,  
a

ccompanied   by   an   audible   signal

river.
It
  is   necessary   to   observe   driving  
r

egulations   and   take   a   break   every

-

i
f there is little contrast between the
markings
  on   the   ground   and   the  
r

You
  are   warned   by   the   vibration   of   the   driver's  
s

eat   cushion:
-
 
o
n   the   right-hand   side,   if   the   marking   on  
t

-
 
o
n   the   left-hand   side,   if   the   marking   on   the  
g

round   has   been   crossed   on   the   left.
No
  warning   is   transmitted   while   the   direction  
i
