system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen lo-
cating the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen lo-
cating the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punc-
t u r e d o r v e r y d e fl a t e d t y r e ) , a n d
have the tyre pressure checked as
soon as possible.
Sensor(s) not detected or faulty
The service warning lamp
comes on in the instrument
panel, accompanied by an
audible signal and a mes-
sage on the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
markings" section) to ensure that
the optimum dynamic performance
of the vehicle is maintained and
prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.

SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- anti-lock braking system (ABS),
- electronic brake force distribu-tion (EBFD),
- emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the
stability and manoeuvrability of your
vehicle when braking, in particular
on poor or slippery surfaces.
Activation
The anti-lock braking system comes
into operation automatically when
there is a risk of wheel lock.
Normal operation of the ABS may
make itself felt by slight vibration of
the brake pedal. Operating fault
When braking in an emergency,
p r e s s v e r y fi r m l y w i t h o u t r e l e a s i n g
the pressure. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
it indicates a malfunction of the anti-
lock braking system which could re-
sult in loss of control of the vehicle
when braking.
If this warning lamp comes on,
together with the STOP and
ABS warning lamps, accom-
panied by an audible signal
and a message on the multifunction
screen, it indicates a malfunction of
the electronic brake force distribution
which could result in loss of control of
the vehicle when braking.
You must stop as soon as it is
safe to do so.
In either case, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
Emergency braking assistance
System which, in an emergency,
enables you to obtain the optimum
braking pressure more quickly, 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
i n c r e a s e i n b r a k i n g e f fi c i e n c y .
When braking in an emergency,
p r e s s fi r m l y w i t h o u t r e l e a s i n g t h e
pressure.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid regulation (also known
as Traction Control) optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme acts
on the brake of one or more wheels
and on the engine to keep the vehicle
on the trajectory required by the driver,
within the limits of the laws of physics.
Deactivation
I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
Press the "ESP OFF" button, lo-
cated in the centre of the dash-
board.
If this warning lamp comes on in
the instrument panel and the in-
dicator lamp on the button comes
on, this indicates that the ASR and
ESP systems are deactivated. T h i s i s i n d i c a t e d b y fl a s h i n g
of this warning lamp on the
instrument panel.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. Intelligent Traction Control
system *
Your vehicle has a system to help
driving on snow.
This automatic system continuously
c h e c k s f o r s i t u a t i o n s o f d i f fi c u l t s u r -
face adhesion that could make it dif-
fi c u l t t o m o v e o f f o r m a k e p r o g r e s s
on deep fresh snow or compacted
snow.
In these situations, the system takes
over from the
ASR system by opti-
mising the amount of wheel slip to
provide the best traction and trajec-
tory control, even without snow tyres
and with or without chains.
I n e x t r e m e l y s e v e r e c o n d i t i o n s ( s n o w
on top of ice, sand, deep mud…), it
can be useful to deactivate the ESP/
ASR systems to allow a degree of
wheel spin and so recover grip.
* Depending on engine type.

audible signal is heard.
Maximum application is essential:
- when towing a caravan or a trail- er, if the automatic functions are
activated but you are applying
the parking brake manually,
- when the gradient you are parked on is variable in its effect (e.g. on
a f e r r y , i n a l o r r y , d u r i n g t o w i n g ) ,
- when towing, when loaded or when parking on a gradient, turn
the front wheels towards the
pavement and engage a gear
when you park,
- after a maximum application, the release time will be longer.
Before leaving the vehicle,
check that warning lamp P
in the instrument panel is
