Automated mode
For optimum acceleration, for example when   overtaking   another   vehicle,   press   the  
a

ccelerator   pedal   firmly   past   the   point   of  
r

esistance.
The
  gearbox   operates   in   auto-active   mode,  
w

ithout   any   action   on   the   part   of   the   driver.  
It   continuously   selects   the   most   suitable   gear  
fo

r:
-  
o
ptimisation   of   fuel   consumption,
-  
t
he   style   of   driving,
-  
t

Temporary control of gear
changing
You can temporarily take over control of g
ear   changing   using   the   "+" and "-" 
steering  
m

ounted   paddles:   if   the   engine   speed   allows,  
t

he   request   to   change   gear   is   acted   on.
This function allows you to anticipate certain
situations
  such   as   overtaking   a   vehicle   or   the  
a

pproach   to   a   corner.
After
  a   few   moments   without   any   action   on  
t

he   control   paddles,   the   gearbox   resumes  
a

utomatic   control   of   the   gears.
Manual mode
The gears engaged appear in succession   in   the   instrument   panel  
sc

reen.
The
 
gear
 
change   requests   are   only   acted   on   if  
t

he
 
engine
 
speed   permits.
It is not necessary to release the accelerator
during
 
gear
  changes.
When
 
braking   or   slowing   down,   the   gearbox  
c

hanges
 
down   automatically   to   allow   the  
v

ehicle
 
to
 
accelerate   in   the   correct   gear.
On
 
sharp
 
acceleration,   the   gearbox   will   not  
c

Stopping the vehicle
When immobilising the vehicle, with t
he   engine   running,   you   must   place   the  
g

ear   lever   in   neutral   N.
Before
  carrying   out   any   work   in   the  
e

ngine   compartment,   ensure   that   the  
g

parking
  brake   is   applied.
Whatever
  the   circumstances,   you   must  
m

anually   apply   the   parking   brake   when  
p

arking,   unless   the   parking   brake   is  
p

rogrammed   in   automatic   mode.
Before
  switching   off   the   engine,   you   can:
-

ot   be   possible   to   move   the   vehicle.
In both cases, you must apply the parking
brake
 
to   immobilise   the   vehicle.

f   the   driver.   It   continuously   selects   the   most  
s

uitable   gear   according   to   the   style   of   driving,  
t

he profile of the road and the load in the
vehicle.
For   maximum   acceleration   without   touching  
t

he lever, press the accelerator pedal down
fully   (kick   down).   The   gearbox   changes   down  
a

utomatically   or   maintains   the   gear   selected  
u

ntil   the   maximum   engine   speed   is   reached.
On   braking,   the   gearbox   changes   down  a
utomatically   to   provide   efficient   engine  b
raking.
If you release the accelerator sharply, the
gearbox
  will   not   change   to   a   higher   gear   for
