Wheel rims may be damaged or scr
atch-

with them. SEAT recommends the use of
covered snow chains.

The inflation pressure of one or more wheels is much
l
ower than the value set by the driver, or the tyre has
structural damage.
In addition, a audible warning sounds and a text
message is displayed on the instrument panel
screen.
Stop the vehicle! Stop the vehicle safely as soon
as possible. Check all tyres and pressures. Replace
any damaged tyres.

System fault
The contr
ol lamp flashes for approximately 1 minute
and then lights up permanently.
If the tyre is inflated correctly, switch the ignition off
and on again. Re-calibrate the tyre pressure monitor
indicator

specialised workshop.
Several control and warning lamps light up

Tyre pressure monitor system

Instrument panel: warning of loss of
t
yre pressure.
The tyre pressure monitoring system com-
par
es the individual speeds of each wheel
and thus the dynamic radius with the help of
the ABS sensors.
If the rolling circumference of one or more
wheels has changed, the tyre pressure moni-
toring indicator will indicate this on the instru-
ment panel through a warning lamp and a
warning to the driver
›››
Fig. 243. When only
one specific tyre is affected, its position within
the vehicle will be indicated.
Loss of pressure: Check left
tyre pressure!
Wheel tread change
The wheel diameter changes when:
●
Tyre pressure is changed manually.
●
Tyre pressure is insufficient.
●
The tyre structure is damaged.
●
The vehicle is unbalanced because of a
load.
●
The wheels on an axle are subject to a
heavier load (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 indicate anything under certain circum-
stances (e.g. sporty driving, snow-covered or
unpaved roads, or when driving with snow
chains).
Calibrate the tyre pressure monitoring in-
dicator
After changing the tyre pressure or replacing
one or more wheels, the tyre pressure moni-
toring indicator must be recalibrated. Do the
