Practical tips
Tyre monitor system
Fig. 297
Centre console: tyre pressure loss in-
dicator button.
The tyre monitor indicator compares wheel
revolutions and, with this information, the
tread of each wheel using the ABS sensors.
The tyre monitor indicator warns the driver if it
detects a considerable drop in tyre pressure
of one or several tyres while driving. Loss of
tyre pressure will be indicated by the indica-
tor

as well as an audible warning and
sometimes a text message on the instrument
panel display.
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

monitoring indicator or it may not indi-
cate anything under certain circumstances
(e.g. sporty driving, snow-covered or un-
paved roads, or when driving with snow
chains).
Calibrating the tyre monitoring indicator
After changing the tyre pressure or replacing
one or more wheels, the tyre monitoring indi-
cator must be recalibrated. Do the same, for
example, when the front and rear wheels are
swapped.
●
Switch the ignition on.
●
Press and hold down the
 

button until an audible signal is heard.
When driving, the system self-calibrates the
tyre pressure provided by the driver and the
wheels fitted. 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 calibra-
tion

Fig. 294 .
If the tyre monitor system button is pressed
down, the new tyre pressures are confirmed.
WARNING
When the tyres are inflated at different
pressures or at a pressure that is too low
then a tyre may be damaged resulting in a
loss of control of the vehicle and a serious
or fatal accident.
●
If the lamp

lights up, reduce speed im-
mediately and avoid any sudden turning or
braking manoeuvre. Stop when possible,
and check the tyre pressure and status.
●
The tyre monitoring system can only op-
erate correctly if all of the tyres are infla-
ted to the correct pressure when cold.
●
If a tyre has not been punctured and it
does not have to be changed immediately,
drive to the nearest specialised workshop
at a moderate speed and have the tyre
checked and inflated to the correct pres-
sure.
WARNING
Incorrect use of the tyre monitoring indica-
tor button could result in the indicator giv-
ing erroneous messages or prevented from
indicating the danger caused by a defec-
tive tyre
