System and tyre status
The current status of the system and the tyres
can be checked, see MY CAR (p. 108).
1. Select the menu system MY CAR to open
the menus for tyre monitoring.
2.
Select
Tyre monitoring.
The status is colour-coded for each tyre in
accordance with the following:
•
All-green: the system is operating nor-
mally and the tyre pressure in all tyres is
slightly above the recommended level.
•
Yellow wheel: corresponding tyre's pres-
sure is too low.
•
All wheels yellow: two or more tyres have
pressure that is too low.
•
All wheels grey: the system is temporarily
unavailable. It may be necessary to drive
the car for a few minutes at a speed
above 30 km/h before the system
becomes active again.
•
All wheels grey and the message
Tyre
pressure system Service required: an
error has occurred in the system. Contact
a Volvo dealer or workshop.
Clearing warning messages
If a tyre pressure message has been shown
and the TPI warning lamp has been illumi-
nated:
1. Check the tyre pressure on the indicated
tyre/tyres with a tyre pressure gauge.
2. Inflate the tyre/tyres to the correct pres-
sure in accordance with the tyre pressure
label on the driver's side door pillar
(between front and rear doors).
3. Recalibrate the TM system.
NOTE
•
The TM system uses a so-called com-
pensated pressure value, based on
both tyre temperature and ambient
temperature. This means that the tyre
pressure may differ slightly from the
recommended pressures listed on the
tyre pressure label on the driver's side
door pillar (between front and rear
doors). For this reason, it may be nec-
essary to inflate the tyres to a slightly
higher pressure in order to clear a low
tyre pressure message.
•
To avoid incorrect tyre pressure, the
pressure should be checked on cold
tyres. "Cold tyres" means the tyres are
the same temperature as the ambient
temperature (approx. 3 hours after the
car has been driven). After a few kilo-
metres of driving, the tyres warm up
and the pressure increases.
WARNING
•
Incorrect tyre pressure may lead to
tyre failure, which could result in the
driver losing control of the car.
•
The system cannot indicate sudden
tyre damage in advance.
