the deceleration, the hazard warning lamps
come on automatically.
They switch off automatically the first time you
accelerate.
)
You can also switch them off by pressing
the button.
Horn
Audible warning system to aler t other road
users to an imminent danger.
)
Press the central part of the mutlifunction
steering wheel.
Use the horn moderately and only in
the following circumstances:
- immediate danger,
- approaching a location lacking
visibility.
Emergency or
assistance call
This system allows you to make an emergency
or assistance call to the emergency ser vices or
to the dedicated CITROËN ser vice.
For more information on the use of this
function, refer to the "Audio and telematics"
section.

Ty r e u n d e r - i nfl ation detection
System which automatically and continuously
checks the pressure of the tyres while driving.
Sensors fitted in each valve trigger a warning
in the event of problem (speed above 12 mph
(20 km/h)).
Puncture
The tyre under-inflation detection
system is an aid to driving which does
not replace the need for the driver to be
vigilant or to drive responsibly.
Under-infl ated tyre
This warning lamp is displayed on the
instrument panel and/or a message
appears in the screen, accompanied
by an audible signal, to identify the
wheel concerned. The STOP
warning lamp comes on
and/or this warning lamp is displayed on
the instrument panel, accompanied by
an audible signal and a message in the
screen identifying the wheel concerned.
)
Stop as soon as it is safe to do so, avoiding
any sudden movement of the steering
wheel and the brakes.
)
Repair or change the damaged wheel
(punctured or very deflated tyre), and have
the tyre pressure checked as soon as
possible.
)
Check the tyre pressures as soon as
possible.
This check must be carried out when the tyres
are cold.

Safety
Sensor(s) not detected or faulty
A message appears in the screen,
accompanied by an audible signal, to identify
the wheel or wheels which are not detected or
to indicate a malfunction in the system.
Contact a CITROËN dealer or a qualified
workshop to replace the faulty sensor(s). All repairs and changing of tyres on a
wheel fitted with this system must be
carried out by a CITROËN dealer or a
qualified workshop.
If, when changing a tyre, you install a
wheel which is not detected by your
vehicle (example: fitting of snow tyres),
you must have the system reinitialised
by a CITROËN dealer or a qualified
workshop. This system does not avoid the need
to have the tyre pressures checked
regularly (refer to the "Identification
markings" section) to ensure that
the optimum dynamic per formance
of the vehicle is maintained and
prevent premature wear of the
tyres, par ticularly in arduous driving
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.
The tyre under-inflation detection
system may experience temporary
inter ference due to electro-magnetic
emissions on a frequency close to that
used by the system.
This message is also displayed when
one of the wheels is away from the
vehicle (being repaired) or when one
or more wheels without a sensor are
fitted.
If your vehicle is equipped with a spare
wheel, this is not fitted with a sensor.

Braking assistance systems
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (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 par ticular on poor or slippery sur faces.
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.
When braking in an emergency, press
very firmly without releasing the
pressure.
Operating fault
If this warning lamp comes on,
together with the STOP
and ABS
warning lamps, accompanied by an
audible signal and a message in the 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.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, it
indicates a malfunction of the anti-lock braking
system which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.

Safety
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 increase in
braking efficiency.
When braking in an emergency, press
firmly without releasing the pressure.
Trajectory control systems (ESP)
Anti-slip regulation (ASR)
and electronic stability
control (ESC)
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control 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.
Activation
These systems are activated automatically
each time the vehicle is star ted.
They come into operation in the event of a grip
or trajectory problem.
This is indicated by flashing of this
warning lamp in the instrument panel.
Intelligent traction control
system ("Snow motion")
Your vehicle has a system to help driving on
snow: intelligent traction control.
This system detects situations of difficult
sur face adhesion that could make it difficult to
move off or make progress on deep fresh snow
or compacted snow.
In these situations, the intelligent traction
control
limits the amount of wheel slip to
provide the best traction and trajectory control
for your vehicle.
The use of snow tyres is strongly
recommended on sur faces offering low
levels of adhesion.
Page 180 of 396
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), if you are unable to make progress,
it may be advisable to temporarily deactivate
these systems, so that the wheels can spin
freely and allow the vehicle to move.
)
Press the "ESP OFF"
button,
located near the steering wheel.
Reactivation
These systems are reactivated automatically
each time the ignition is switched back on or
from 30 mph (50 km/h).
)
Press the "ESP OFF"
button again to
reactivate them manually.
Operating fault
The trajectory control systems offer
increased safety in normal driving, but
this should not encourage the driver to
take extra risks or drive at high speed.
The correct functioning of these
systems is assured provided that
manufacturer's recommendations are
observed on:
- wheels (tyres and rims),
- braking components,
- electronic components,
- assembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, this
indicates a fault with these systems.
Have it checked by a CITROËN dealer or a
qualified workshop. It is recommended that the systems be
reactivated as soon as possible.
If this warning lamp comes on in the instrument
panel and the indicator lamp in the button
comes on, this indicates that these systems are
deactivated.
