Operation
Gear efficiency indicator
System which reduces fuel consumption by recommending the most suitable gear.
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

Example:
The
  information   appears   in   the   instrument  
p

anel   in   the   form   of   an   arrow.
On
  vehicles   with   manual   gearbox,   the   arrow  
c

an   be   accompanied   by   the   recommended  
g

e a r.
Depending
  on   the   driving   situation   and   your  
v

ehicle's   equipment,   the   system   may   advise  
y

ou   to   skip   one   or   more   gears.
You
  can   follow   this   instruction   without   going  
t

hrough   the   intermediate   gears.
The
  gear   engagement   recommendations   must  
n

ot   be   considered   compulsory.
This
  is   because   the   configuration   of   the   road,  
t

raffic   density   and   safety   remain   important  
f

actors   in   the   choice   of   the   best   gear.
So
  the   decision   to   follow   or   not   the   indications  
f

rom   the   system   remains   with   the   driver.-
 
Y

-
 
Y
ou   press   the   accelerator   pedal.

T
he   system   may   suggest   that   you   engage  
a

  higher   gear.
With
  an   electronic   or   automatic   gearbox,   the   system   is   only   active   in   manual   mode.

Stop & Start
The Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...). 
T he   engine   restarts   automatically   -   START   mode   -   as   soon   as   you   want   to   move   off.   The   restart   takes   place   instantly,   quickly   and   silently.
Operation
Going into engine STOP
mode
The "ECO" warning   lamp   comes   on   in   the  i
nstrument   panel   and   the   engine   goes   into  
s

tandby
 a
utomatically:
-
 
w
ith a manual gearbox,   at   speeds   below  
1

2   mph   (20   km/h),   or   vehicle   stationary  
(

with   e-THP   130   and   165   petrol   versions  
a

nd   BlueHDi   100,   115   and   120   versions),  
w

hen   you   place   the   gear   lever   in   neutral,  
a

nd   you   release   the   clutch   pedal,
-
 
w
ith an electronic gearbox,   at   speeds  
b

elow   5   mph   (8   km/h),   when   you   press   the  
b

rake   pedal   or   place   the   gear   selector   lever  
i

n position N ,
-
 
w
ith an automatic gearbox, with the
vehicle stationary, when you press the
brake
  pedal   or   place   the   gear   selector   lever  
i

n position N . Never
  refuel   with   the   engine   in   STOP  
m

ode;   you   must   switch   off   the   ignition  
w

ith   the   START/STOP   button.
For
  your   comfort,   during   parking  
m

anoeuvres,   STOP   mode   is   not  
a

vailable   for   a   few   seconds   after  
c

oming   out   of   reverse   gear.
STOP
  mode   does   not   affect   the  
f

unctionality of the vehicle, such as for
example,
  braking,   power   steering...
Special cases: STOP mode not
available
STOP mode is not invoked when:
-  t he   driver's   door   is   open,
-
 
t
he   driver's   seat   belt   is   not   fastened,
-
 
t
he   vehicle   has   not   exceeded   6   mph  
(

10 km/h)   since   the   last   engine   start   using  
t

he   START/STOP   button,
-
 
t
he   electric   parking   brake   is   applied   or  
be

ing
 a
pplied,
-
 
t
he   engine   is   needed   to   maintain   a  
c

omfortable   temperature   in   the   passenger  
c

ompartment,

e

ngine   temperature,   braking   assistance,  
a

mbient   temperature...)   where   the   engine   is  
n

eeded   to   assure   control   of   a   system.
In this case, the "ECO"
 

warning   lamp  
f

lashes   for   a   few   seconds   then   goes

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   vigilance   or   the  
r

esponsibility   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.
See
  the   "Identification   markings"  
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.

Operation
When a petrol filler nozzle is introduced into the f
