If one of the doors or the boot is still
open,  the   central   locking   does   not

s

ound   of   the   locks   rebounding.
When
  the   vehicle   is   locked,   if   it   is

Locking using the key
F Turn   the   key   in   the   driver's   door   lock,  t
owards   the   rear   of   the   vehicle   to   lock   it.This function allows you to identify your vehicle

Locating your vehicle
Anti-theft protection
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
  electronic   engine   immobiliser   locks   the  
e

ngine   management   system   a   few   moments  
a

fter   the   ignition   is   switched   off   and   prevents  
s

tarting   of   the   engine   by   anyone   who   does   not  
h

ave   the   key.In the event of a fault, you are
informed
  by   illumination   of   this  
w

arning   lamp,   an   audible   signal  
a

nd   a   message   in   the   screen.

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.
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

f vehicles used in town, over short
distances.

In
  order   to   optimise   the   operation   of

o

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

r   in   wintry   conditions,   ice   can   form  
o

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

oticed,   the   parking   brake   must   be

Checking
  this   system   must   be   done   by   a
