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.

Electric parking brake


The electric parking brake combines
2 operational modes:


- Automatic Application/Release

Application is automatic when the engine
stops, release is automatic on use of the
accelerator (activated by default),

- Manual Application/Release

The parking brake can be applied/released
manually by pulling control lever A
.
Do not place any object (packet of
cigarettes, telephone...) between the
gear lever and the electric parking
brake control lever.
It is recommended that you do not
apply the parking brake in very cold
conditions (ice) and during towing
(breakdown, caravan...). Deactivate the
automatic functions and release the
parking brake manually.

If this warning lamp comes on in
the instrument panel, the automatic
mode is deactivated.

Programming the mode

Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release when
you press the accelerator can be deactivated.
Activation/deactivation is done
using the vehicle configuration
menu; refer to the section covering
the configuration of your vehicle's
systems.
The parking brake is then applied and released
manually. When the driver's door is opened,
there is an audible signal and a message is
displayed if the brake is not applied.

lever A
, until you see the message "Handbrake
on maximum" and a beep is heard.

Maximum application is essential:



- in the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,

- when the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing),

In the case of towing, a loaded vehicle
or parking on a gradient, make a
maximum application of the parking
brake then turn the front wheels
towards the pavement and engage a
gear when you park.
After a maximum application, the
release time will be longer.
