In bad weather and in winter, ensure that   the   sensors   are   not   covered   by  
r

oad   dirt,   ice   or   snow.
In
  the   event   of   a   fault,   have   the   system

In good or rainy weather, both day and   night,   the   front   foglamps   and   the  
r

ear   foglamp   are   prohibited.   In   these  
s

ituations,   the   power   of   their   beams  
m

ay   dazzle   other   drivers.   They   should  
o

nly   be   used   in   fog   or   snow.
In
  these   weather   conditions,   it   is   your  
r

esponsibility   to   switch   on   the   foglamps  
a

nd   dipped   beam   headlamps   manually  
a

s   the   sunshine   sensor   may   detect  
s

Do
  not   forget   to   switch   off   the   front  
f

oglamps   and   the   rear   foglamp   when  
t

hey   are   no   longer   necessary.Switching off the lamps
when the ignition is
switched off
On switching off the ignition, all of the lamps turn   off   immediately,   except   for   dipped   beam i

f   guide-me-home   lighting   is   activated.
Switching on the lamps
after the ignition is
switched off
To reactivate the lighting control, rotate the   ring   to   the   "0"  position   -   lamps   off,  
t

hen   to   the   desired   position.
On
  opening   the   driver's   door   a  
t

emporary   audible   signal   warns   the  
d

river   that   the   lighting   is   on.
The
  lamps,   with   the   exception   of   the

a

  maximum   duration   of   thirty   minutes   to

Special position of the
windscreen wipers
To maintain the effectiveness of the flat wiper   blades,   it   is   advisable   to:
-
 
h
andle   them   with   care,
-
 
c
lean   them   regularly   using   soapy  
w

ater,
-
 
a
void   using   them   to   retain

It
 
is
 
used
 
for

replacement
 
of

lades.
 
It
 
can
 
also
 
be
 
useful,
 
in

to
 
d

etach

Under-inflation detection
The system monitors the pressures in the four t
yres,   once   the   vehicle   is   moving.
It
  compares   the   information   given   by   the   four  
w

heel   speed   sensors   with   reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed .
The
  system   triggers   an   alert   as   soon   as   it  
d

etects   a   drop   in   the   inflation   pressure   of   one  
o

r   more   tyres. The
  under-inflation   detection   system  
d

oes   not   replace   the   need   for   vigilance  
o

n   the   part   of   the   driver.
This
  system   does   not   avoid   the   need   to  
c

heck   the   tyre   pressures   (including   the  
s

pare   wheel)   every   month   as   well   as  
b

efore   a   long   journey.
Driving
  with   under-inflated   tyres   impairs  
r

oad   holding,   extends   braking   distances  
a

nd   causes   premature   tyre   wear,  
p

articularly   under   arduous   condition  
(

high   loading,   high   speed,   long   journey).
System
  which   automatically   checks   the   pressures   of   the   tyres   while   driving.
The   inflation   pressures   defined   for  
y

our   vehicle   can   be   found   on   the   tyre  
p

ressure   label.
See
  the   "Identification   markings"  
s

ection.
Tyre
  pressures   should   be   checked  
w

hen   the   tyres   are   "cold"   (vehicle  
s

topped   for   1   hour   or   after   a   journey   of  
l

ess   than   6   miles   (10   km)   at   moderate  
s

peeds).
Other wise
  (when   hot),   add   0.3   bar   to  
t

he   pressures   shown   on   the   label.
Driving
  with   under-inflated   tyres  
i

ncreases   fuel   consumption.

Driving advice
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that  t
he heaviest   items   are   as   close   as  
p

ossible   to   the   axle   and   the   nose   weight  
a

pproaches   the   maximum   permitted  
w

ithout   exceeding   it.
Air
  density   decreases   with   altitude,   thus  
r

educing   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

S

TOP
 
warning   lamp   come   on,  
s

top   the   vehicle   and   switch   off  
t

he   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.
