Boot lampPanoramic s unroof
This glazed roof provides increased visibility a

m

aintaining   normal   temperatures   thanks   to   its  
"

high   thermal   protection"   coating.
Advice on care
In order to preserve the properties of the glazed   roof,   we   recommend   wiping   or   cleaning  
t

he   inner   glass   using   a   clean,   soft   and   dry
cloth.
For
  stubborn   stains,   the   glass   should   be  
c

leaned   using   screenwash   fluid,   rinsed   with  
c

lean   water,   then   dried   with   a   clean,   soft   cloth.
Do not use soapy water, abrasive
products,
  detergents   (particularly   those  
w

ith   an   ammonia   base),   solvents,  
s

olutions   with   a   high   concentration   of  
a

When towing
Distribution of loads
F Distribute  the   load   in   the   trailer   so   that   the  h
eaviest   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  
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.
For
  more   information   on   weights   (and   the  
t

owed   loads   which   apply   to   your   vehicle)   refer  
t

o   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  
t

he   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

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

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  
t

he   engine   is   hot,   the   warning   lamp  
d

oes   not   come   on. In
  temperate   conditions,   do   not   leave  
t

he   engine   at   idle   to   warm   up   but   move  
o

ff   straight   away   and   drive   at   moderate  
s

peed.
Never   leave   the   engine   running   in  
a

n   enclosed   area   without   adequate  
v

entilation:
 in
ternal
 c
ombustion
 e

ngines   emit   toxic   exhaust   gases,  
s

uch   as   carbon   monoxide.   Danger   of  i
ntoxication   and   death.
In   very   severe   wintry   conditions  
(

temperatures   below   -23°C),   to   ensure  
t

he   correct   operation   and   durability   of  
t

he   mechanical   components   of   your  
v

ehicle,   engine   and   gearbox,   it   is  
n

ecessary   to   leave   the   engine   running  
f

or   4   minutes   before   moving   off.
If
  the   engine   does   not   start   straight  
a

way,   switch   off   the   ignition.   Wait   a   few  
m

oments   before   operating   the   starter  
m

otor   again.   If   the   engine   does   not  
s

tart   after   several   attempts,   do   not   keep  
t

rying:   you   risk   damaging   the   starter  
m

otor   or   the   engine.
