Driving advice
Your vehicle is designed principally to drive   on   tarmac   roads   but   it   allows   you  
t

o   drive   on   other   less   passable   terrain  
o

ccasionally.
However,
  it   does   not   permit   off-road  
d

riving   such   as:
-
 
c
rossing   and   driving   on   terrain  
w

hich   could   damage   the   underbody  
o

r   strip   away   components   (fuel  
p

ipe,   fuel   cooler...)   due   to   obstacles  
o

r stones in particular,
-
 
d
riving   on   terrain   with   steep  
g

radients   and   poor   grip,
-
 
c
rossing   a   stream.All terrain (mud, damp grass, ...)
This mode, when moving off, allows considerable   spin   on   the   wheel   with   the   least  
g

rip   to   optimise   clearing   of   the   mud   and   regain  
g

rip.   At   the   same   time,   the   wheel   with   the   most  
g

rip   is   controlled   in   such   a   way   as   to   pass   as  
m

uch   torque   as   possible.
When
  moving,   the   system   optimises   wheel   spin  
t

o   respond   to   the   driver's   requirements   as   fully  
a

s   possible.

F
 
P
lace   the   dial   in   this   position.
Sand
This mode allows little spin on the two driving wheels   at   the   same   time   to   allow   the   vehicle   to  
m

ove   for ward   and   limit   the   risks   of   getting   stuck  
i

n   the   sand.
(mode
  active   up   to   75   mph   (120   km/h))
F
 
P
lace   the   dial   in   this   position.
Do
  not   use   the   other   modes   on   sand   as   the  
v

ehicle   may   become   stuck. You
  can   deactivate   certain   functions   of   the  
ES

C   (ASR   and   DSC)   by   turning   the   dial   to   the  
"
O
FF
"   position.
These   functions   are   reactivated   automatically

rom   30   mph   (50   km/h)   or   every   time   the  
i

gnition   is   switched   back   on.

Operation
Gear efficiency indicator
System which reduces fuel consumption by advising the driver to change up, on vehicles fitted with a manual gearbox.
T he   system   adapts   its   gear   change  
r

ecommendation   according   to   the  
d

riving   conditions   (slope,   load, ...)   and  
t

he   demands   of   the   driver   (power,  
a

cceleration,   braking, ...).
The
  system   never   suggests:
-
 
e
ngaging   first   gear,
-
 enga

ging
 r
everse
 g
ear,
-
 
e
ngaging   a   lower   gear.
Example:
-
 
Y
ou   are   in   third   gear.
Depending
  on   the   driving   situation   and   your  
v

ehicle's   equipment,   the   system   may   advise  
y

ou   to   skip   one   (or   more)   gear(s).   You   can  
f

ollow   this   instruction   without   engaging   the  
i

ntermediate
 g
ears.
-
 
Y
ou   press   the   accelerator   pedal.
-
 
T
he   system   may   suggest   that   you   engage  
a

  higher   gear.
The
  information   appears   in   the   instrument  
p

anel   in   the   form   of   an   arrow,   accompanied   by  
t

he   recommended   gear.
On
  certain   Diesel   versions   with   manual  
g

earbox,   the   system   may   suggest  
c

hanging   into   neutral   (N
  is   displayed   in  
t

he   instrument   panel)   so   that   the   engine  
c

an   go   into   standby   (STOP   mode  
w

ith   Stop   &   Start),   in   certain   driving  
c

onditions.
The
  gear   engagement   recommendations   must  
n

ot   be   considered   compulsory.   In   fact,   the  
c

onfiguration   of   the   road,   the   amount   of   traffic  
a

nd   safety   remain   determining   factors   when  
c

hoosing   the   best   gear.   Therefore,   the   driver  
r

emains   responsible   for   deciding   whether   or   not  
t

o   follow   the   advice   given   by   the   system.
This
  system   cannot   be   deactivated.

D
  and   the   gear   engaged   appear   in  
t

he   instrument   panel.
The
  gearbox   then   operates   in   auto-adaptive  
m

ode,   without   any   action   on   the   part   of   the  
d

river.   It   continuously   selects   the   most   suitable  
g

ear   taking   account   of:
-
 
o
ptimisation   of   fuel   consumption,
-
 
d
riving   style,
-
 
r
oad   conditions,
-
 
v
ehicle   load.
For
  optimum   acceleration,   when  
ov

ertaking   another   vehicle   for   example,  
p

ress   the   accelerator   pedal   fully   down,  
b

eyond   the   point   of   resistance.
Temporary control of gear
changing
You can temporarily take over control of gear changes   using   the   steering   mounted   "+"  and "-"
control
  paddles:   if   the   engine   speed   allows,   the
 g

ear   change   is   carried   out.

  or   when   you   press   the   brake  
ped

al. Never

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.
For
  more   information   on   the  
i

dentification   markings,   refer   to   the  
c

orresponding
 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.

Fuel tank
Capacity of the tank:
- Pe trol:   approximately   50   litres.
-
 
D
iesel:   approximately   45   or   50   litres   (depending   on   version).
Low fuel levelRefuelling
When the low fuel level is reached, t
his   warning   lamp   in   the   instrument  
p

anel   comes   on,   accompanied   by  
a

n   audible   warning,   a   message   and  
t

he   last   bar   of   the   fuel   gauge   flashes  
i

n   red.
To
  refuel   in   complete   safety:
F

Y
ou must switch off the engine.

O
pen   the   filler   flap.
A
  label   on   the   inside   of   the   fuel   filler   flap  r
eminds   you   of   the   type   of   fuel   to   use,  
d

epending   on   your   engine   type.
Additions
  of   fuel   must   be   of   at   least   5   litres   to  
b

e   registered   by   the   fuel   gauge.
When
 
it
 
first   comes   on,   about 5 litres of fuel
remain
 
in
 
the   tank.
Until
 
sufficient   fuel   has   been   added,   this  
w

arning
 
lamp   appears   every   time   the   ignition  
i

s
 
switched   on,   accompanied   by   an   audible  
w

arning
 
and   a   message.   This   audible   warning  
a

nd
 
message   are   repeated   with   increasing  
f

requency
  as   the   fuel   level   drops   towards   "0 ".
Refuel
 
as
 
soon   as   possible   to   avoid   running   out.Opening
  the   filler   cap   may   result   in   an   inrush   of  
a

ir.   This   is   entirely   normal   and   results   from   the  
s

ealing   of   the   fuel   system.
With Stop & Start, never refuel with the
system
  in   STOP   mode;   you   must   switch  
o
