Tyre monitoring indicator
Fig. 253 Instrument panel: warning of loss of
ty
r
e pr
essure.
The tyre monitor indicator compares wheel
r
ev
o
lutions and, with this information, the
tread of each wheel using the ABS sensors. If
the rolling circumference of one or more
wheels has changed, the tyre monitoring in-
dicator will indicate this on the instrument
panel through a warning lamp and a warning
to the driver ››› Fig. 253. When only one spe-
cific tyre is affected, its position within the
vehicle will be indicated.
Loss of pressure: Check left
tyre pressure!
Wheel tread change
The wheel tread changes when:
●
Tyre pressure is manually changed
●
Tyre pressure is insufficient
●
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 monitoring indicator or it may not in-
dicate anything under certain circumstances
(e.g. sporty driving, snow-covered or un-
paved roads, or when driving with snow
chains).
