System which reduces fuel consumption by recommending the most appropriate gear.
Gear shift indicator
Operation
Example:
- Y ou   are   in   third   gear.
-
 
Y
ou   press   the   accelerator   pedal.
-
 
T
he   system   may   suggest   that   you   engage  
a

  higher   gear.
Depending
  on   the   driving   situation   and   your  
v

ehicle's   equipment,   the   system   may   advise  
y

ou   to   change   gear.
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   function   cannot   be   deactivated.
The   information   appears   in   the  
i

nstrument   panel   in   the   form   of   an  
a

r row. The
  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.
With
  an   ETG   electronic   gearbox,   the  
s

ystem   is   only   active   in   manual   mode.
With   the   PureTech   82   engine,   the  
s

ystem   only   suggests   when   to  
c

hange up.

Operation
Going into engine STOP

This indicator lamp comes on in the instrument   panel   and   the   engine  
g

elease   the   clutch   pedal.
Never
  refuel   with   the   engine   in  
S

TOP mode;   you   must   switch   off   the  
i

gnition   with   the   button.
For
  smoother   operation,   during  p
arking   manoeuvres   STOP   mode   is  n
ot   available   for   a   few   seconds   after  
c

oming   out   of   reverse   gear.
The
  Stop   &   Start   does   not   affect   the  
v

ehicle's   systems,   such   as   for   example,  
b

raking,   power   steering...

Electronic Stability Control (ESC) incorporating the   following   systems:

Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
These systems improve the stability and manoeuvrability   of   your   vehicle   when   braking  
a

nd   contribute   towards   better   control   in  
c

orners,   in   particular   on   poor   or   slippery   road  
su

rfaces.
The
  ABS   prevents   wheel   lock   in   the   event   of  
em

ergency
 b
raking.
The
  electronic   brake   force   distribution   system  
m

anages   the   braking   pressure   wheel   by   wheel.
Emergency braking assistance
In an emergency, this system enables you to reach   the   optimum   braking   pressure   more  
q

uickly   and   therefore   reduce   the   stopping  
di

stance.
It
  is   triggered   according   to   the   speed   at   which  
t

he   brake   pedal   is   pressed.   This   is   felt   by   a  
r

eduction   in   the   resistance   of   the   pedal   and   an  
i

ncrease   in   the   effectiveness   of   the   braking.
Traction control (TRC)
This system optimises traction in order to limit wheel   slip   by   acting   on   the   brakes   of   the   driving  
w

heels   and   on   the   engine.   It   also   improves  
t

he   directional   stability   of   the   vehicle   on  
a

cceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed   by   the   vehicle   and   that   required   by   the  
d

river,   this   system   monitors   each   wheel   and  
a

utomatically   acts   on   the   brake   of   one   or   more  
w

heels   and   on   the   engine   to   return   the   vehicle  
t

o   the   required   path,   within   the   limits   of   the   laws  
o
