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
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.

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.
