TYRE PRESSURE LOSS WARNING (1/3)
If fitted on the vehicle, this system
warns the driver of pressure loss in one
or several tyres.
In the following situations, the system
risk coming into action late or not func-
tioning correctly:
– system not reset after reinflation or
any operation on the wheels;
– system badly reset: different inflation
pressures from the recommended
pressures;
– significant change in load or distribu-
tion of load on one side of the vehi-
cle;
– sporty driving with strong accelera-
tion;
– driving on snowy or slippery surface;
– driving with snow chains;
– fitting a single new tyre;
– use of tyres not approved by the net-

Operating principle
This system detects a loss of pressure
in one of the tyres by measuring the
wheel speed while driving.
Warning light
1 comes on to
alert the driver in the event of insuffi-
cient pressure (deflated wheel, punc-
tured tyre, etc.).
Operating conditions
The system should be reset with an
inflation pressure equal to that given
on the tyre inflation pressure label.
Otherwise it risks not giving a reliable
warning in the event of a significant loss
of pressure. Please refer to the informa-
tion on “Tyre pressures” in Section 4.
This function is an additional driving aid.
However, the function does not take the place of the driver. It cannot,
therefore, under any circumstances replace the vigilance or the respon-
sibility of the driver.
Check the tyre pressures, including the emergency spare wheel, once a month.
