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
  refuel   with   the   engine   in   STOP  
m

ode;   you   must   switch   off   the   ignition  
w

The system is reactivated automatically at   every   new   start   using   the   key.
Reactivation
This system requires a battery with a special specification   and   technology   (reference  
n

q

ualified
 w
orkshop).
Fitting
  a   battery   not   listed   by   CITROËN

Hill start assist
System which holds your vehicle temporarily (approximately   2   seconds)   when   starting   on   a  
s

lope,   the   time   it   takes   to   move   your   foot   from  
t

he   brake   pedal   to   the   accelerator   pedal.
This
  function   is   only   active   when:
-
 
t
he   vehicle   is   completely   stationary,   with  
y

our   foot   on   the   brake   pedal,
-
 
c
ertain   conditions   on   a   slope   are   met,
-
 
w
ith   the   driver’s   door   closed.
The hill start assist function cannot be
deactivated.
On an ascending slope, with the vehicle
stationary, the vehicle is held momentarily
when you release the brake pedal:
-
 
p
rovided   you   are   in   automated   mode  
(

position A)
  or   in   manual   mode   (position   M)
on
  an   electronic   gearbox.
Do not leave the vehicle while it is
being
  held   in   the   hill   start   assist   phase.
If you need to leave the vehicle with
the
  engine   running,   manually   apply  
t

he   parking   brake   then   ensure   that   the  
p

arking   brake   warning   lamp   is   on   (not  
f

lashing)   in   the   instrument   panel.Operation
On a descending slope, with the vehicle
stationary and reverse gear engaged, the
vehicle is held momentarily when you
release the brake pedal.

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
 e

fficiency.
When
  braking   in   an   emergency,   press  
f

irmly   without   releasing   the   pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
programme (ESP)
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   programme   acts   on   the  
b

rake   of   one   or   more   wheels   and   on   the   engine  
t

o   keep   the   vehicle   on   the   trajectory   required  
b

y   the   driver,   within   the   limits   of   the   laws   of  
p

hysics.Activation
These systems are activated automatically each   time   the   vehicle   is   started.
They

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  
a

utomatically   put   out   of   service:   it   no

You
  must   go   to   a   CITROËN   dealer   or   a  
q

ualified   workshop   to   have   the   system  
m

ade   operational   again.
During
  automatic   braking,   the   driver  
c

an   always   obtain   a   higher   rate   of  
d

eceleration than that controlled by the
system,
  by   pressing   firmly   on   the   brake  
ped

al.
The
  triggering   of   the   system   may   cause  
t

he   engine   to   stall,   unless   the   driver  
d

epresses   the   clutch   pedal   quickly  
e

nough   during   automatic   braking.

(petrol or d iesel)).
Low fuel level
Filling
A label affixed to the inside of the flap reminds you   of   the   type   of   fuel   to   be   used   depending   on  
y

Additions
  of   fuel   must   be   of   at   least   7   litres,   in  
o

  key   cannot   be   removed   from   the  
l

ock   until   the   cap   is   refitted.
Opening
  the   filler   cap   may   create   a  
n

oise   caused   by   an   inrush   of   air.   This  
v

acuum   is   entirely   normal,   resulting  
f

rom   the   sealing   of   the   fuel   system.
To
  fill   the   tank   safely:
F

t
he engine must be switched off,
F

o
pen the fuel filler flap,
F
 
i
nsert   the   key   in   the   cap,   then   turn   it   to   the  
l

eft,F
 r emove   the   cap   and   hook   it   onto   the   clip  
l

ocated on the inside of the flap,
F
 
f
ill   the   tank,   but do not continue after the
3rd cut- off of the pump ;
  this   could   cause  
m

alfunctions.
When
  you   have   filled   the   tank:
F
 
p
ut   the   cap   back   in   place,
F
 
t
urn   the   key   to   the   right,   then   remove   it  
f

F
 
c
lose   the   flap.
When
  the   fuel   tank   minimum   level  
i

s   reached   this   warning   lamp   comes  
o

n   on   the   instrument   panel.   When   it  
f

irst   comes   on   there   remains   approximately
5 litres   of   fuel   in   the   tank.
You   must   refuel   as   soon   as   possible   to   avoid  
r

unning   out   of   fuel.
If you run out of fuel (Diesel), refer also to the
"Checks"
 s
ection.
With Stop & Start, never refuel with the
system   in   STOP   mode;   you   must   switch  
o

ff   the   ignition   with   the   key.
