Operating faults
In the event of a fault with the power
steering, this warning lamp flashes in
the instrument panel, accompanied
by a message.
Contact a CITROËN dealer or a qualified
workshop.
Switching off
If the lateral distance between your
vehicle and the space is too great, the
system may not be able to measure the
space.
Anything projecting beyond the envelope
of the vehicle (a ladder on the roof, for
example) is not taken into account by the
Park Assist system during a manoeuvre.
In bad weather or in winter, ensure that
the sensors are not covered by road
dirt, ice or snow.
In the event of a fault, have the system
checked by a CITROËN dealer or a
qualified workshop.
If the system is deactivated during a
manoeuvre, the drive should reactivate
it to repeat the measurement. In the event of a fault, this warning
lamp flashes for a few seconds,
accompanied by an audible signal.
If the fault occurs during the use
of the system, the warning lamp
goes

off. High pressure jet washing
When washing your vehicle, keep the
lance at least 30 cm away from the
sensors.

Under-inflation detection
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
Driving with under-inflated tyres
increases fuel consumption. Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for
1
hour or after a journey of less than
6
miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the pressures
shown on the label.
