Tyre Pressure Monitoring (Tpms)* Rectifying Low Tyre Pressure; Tyre Pressure Monitoring (Tm) - Volvo V 70 Owner's Manual

Tyre pressure monitoring (TPMS)*
rectifying low tyre pressure
The tyre pressure monitoring system TPMS
(Tyre Pressure Monitoring System)
the driver when the pressure is too low in one
or more of the car's tyres and indicates the
tyre to which it applies. The lamp illuminates
in yellow at the first indication, stop and
check the tyre pressure as soon as possible.
When the lamp illuminates in red you must
stop and rectify the tyre pressure immedi-
ately.
If a message for low tyre pressure is shown in
the display:
1. Check the tyre pressure on the tyre in
question.
2. Inflate the tyre(s) to the correct pressure.
3. Drive at least at 30 km/h for several
minutes and check that the message dis-
appears.

Tyre pressure monitoring (TM)*

The TM (Tyre Monitor) system senses tyre
rotation speed in order to determine whether
the tyres have the correct tyre pressure. If the
27 warns
pressure is too low, the tyre's diameter is
changed and, as a result, so is the rotation
speed. By comparing the tyres with each
other the system can determine whether one
or more tyres have pressure that is too low.
Messages
If the tyre pressure is too low then a warning
lamp ( ) illuminates in the combined instru-
ment panel and one of the following mes-
sages is shown:
•

IMPORTANT
If a fault occurs in the TM system the
warning lamp
ment panel will flash for approx. 1 minute
and then illuminate with a constant glow. A
message is also shown in the combined
instrument panel.
The system does not replace normal tyre
maintenance.
TM recalibration
In order for TM to work correctly, a reference
value for the tyre pressure must be deter-
mined. This must be performed each time the
tyres are changed or the tyre pressure is
changed.
