There is a risk of damage to the gearbox:
- i f you press the accelerator and
brake
  pedals   at   the   same   time,
-
 
i
f   you   force   the   movement   of   the  
s

elector   from   the   P position to
another position when the battery
is

f   this   warning   lamp,   accompanied  
b

y
 
an
 
audible   signal   and   a   message   in   the  
m

ultifunction   screen,   indicates   a   gearbox   fault.
In
 
this
 
case,   the   gearbox   switches   to   back-up  
m

ode
 
and
 
is   locked   in   3rd   gear.   You   may   feel  
a

 
substantial   knock   when   changing   from   P
to R
 
and
 
from  n to R .
  This   will   not   cause   any

Stopping the vehicle
Before switching off the engine, you can engage p osition P or
n 
to   place   the   gearbox   in   neutral.
In
  both   cases,   apply   the   parking   brake   to  
i

mmobilise   the   vehicle.
Invalid value during manual
operation
If the engine speed is too low or too high, the gear   selected   flashes   for   a   few   seconds,   then  
t

he   actual   gear   engaged   is   displayed.
It
  is   possible   to   change   from   position  d
(automatic)
  to   position   M   (manual)   at   any   time.
When
  the   vehicle   is   stationary   or   moving  
v

ery   slowly,   the   gearbox   selects   gear   M1
automatically.
The
  sport   and   snow   programmes   do   not

Stop & StartThe Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). The engine   restarts   automatically   -   START   mode   -   as   soon   as   you   want   to   move   off.   The   restart   takes   place   instantly,   quickly   and   silently.
Per fect
  for   urban   use,   the   Stop   &   Start   system   reduces   fuel   consumption   and   exhaust   emissions   as   well   as   the   noise   level   when   stationary.
Operation
going into engine STOP mode
For your comfort, during parking manoeuvres,   STOP   mode   is   not  
a

vailable for a few seconds after
coming
  out   of   reverse   gear.
STOP
  mode   does   not   affect   the  
f

unctionality of the vehicle, such as for
example,
  braking,   power   steering...
Never

Emergency braking assistance
System which, in an emergency, enables you to   obtain   the   optimum   braking   pressure   more  
q

uickly,   thus   reducing   the   stopping   distance.
Activation
It is triggered by the speed at which the brake pedal   is   pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking

The anti-slip regulation (also known as traction control)   optimises   traction   to   prevent   skidding  
o

f   the   wheels,   by   acting   on   the   brakes   of   the  
d

riving   wheels   and   on   the   engine.
The electronic stability control acts on the

Operation
When your vehicle is too close to or
approaches  the   vehicle   ahead   too   quickly   the  
s

ystem   automatically   applies   the   brakes   to  
a

void   a   collision.
The
  collision   can   be   avoided   automatically   if   the
 d

ifference in speed between your vehicle and the
vehicle
  ahead   does   not   exceed   9   mph   (15   km/h).
Above
  this   threshold,   the   system   will   do   what
 i

s possible to avoid or reduce the accident by
lowering
  the   speed   of   impact.
The
  automatic   braking   may   bring   the   vehicle   to  
a

  complete   stop   if   the   situation   requires   it.
In this case, the vehicle is held stationary
temporarily
  (for   about   1.5   seconds)   to   allow  
t

he   driver   to   take   back   control   by   pressing   the  
b

rake
 ped
al.
You are then alerted by the display of a
message.
The
  brake   lamps   on   your   vehicle   come   on   to  
w

arn   other   road   users.
After
  an   impact,   the   system   is

You

During

system,
  by   pressing   firmly   on   the   brake

The system is deactivated in the vehicle configuration   menu,   accessible   with   the   ignition   on.
Its
