Seat Tarraco 2022 - Tyre Pressure Monitor System

Wheels and tyres
●
Check the tyre pressure of the newly moun-
t
ed tyre as soon as possible.
●
In vehicles fitted with a tyre pressure indica-
tor, adjust the pressure and store it in memory
›››page362.
●
Have the tightening torque of the wheel nuts
checked as soon as possible with a torque
wrench ›››page361. Meanwhile, drive care-
fully.
●
Have the flat tyre replaced as quickly as pos-
sible.

Tyre pressure monitor indicator
Fig.257 Instrument panel
: warning of loss of
tyre pressure.
The tyre pressure monitoring system compares
the individual speeds of each wheel and thus
the dynamic r
adius with the help of the ABS
sensors.
If the rolling circumference of one or more
wheels has changed, the tyre pressure monitor-
ing indicator will indicate this on the instrument
panel through a warning lamp and a warning to
the driver ›››Fig.257. When only one specific
tyre is aected, its position within the vehicle
will be indicated.
Loss of pressure: Check left tyre
pressure!
Wheel tr
ead change
The wheel diameter changes when:
●
Tyre pressure is changed manually.
●
Tyre pressure is insucient.
●
The tyre structure is damaged.
●
The vehicle is unbalanced because of a load.
●
The wheels on an axle are subject to a heav-
ier l
oad (e.g. with a heavy load).
●
The vehicle is fitted with snow chains.
●
The temporary spare wheel is fitted.
●
The wheel on one axle is changed.
There may be a delay in the reaction of the tyre
pressure monitoring indicator
or it may not
indicat
e anything under certain circumstances
(e.g. sporty driving, snow-covered or unpaved
roads, or when driving with snow chains).
Calibrate the tyre pressure monitoring indi-
cat
or
After changing the tyre pressure or replacing
one or more wheels, the tyre pressure moni-
toring indicator must be recalibrated. Do the
same, for example, when the front and rear
wheels are swapped.
It should be calibrated with the vehicle stopped
and its tyres cold. If calibrated while the tyres
are hot, the pressure check and calibration pro-
cedure should be repeated when cold before
the next trip.
●
Switch the ignition on.
●
Save the new inflation pressure in the Info-
tainment system: function button

cle status > Tyres; OR:

The t
yre pressure loss indicator uses the
ABS sensors to compare the turns of each
wheel and, therefore, their tread circumferen-
ces, among other aspects. After a long journey
with varied speeds the programmed values are
collected and monitored.
With the wheels under very heavy loads, the
tyre pressure must be increased to the total
recommended tyre pressure before the calibra-
tion ›››Fig.257.
