Color indications:
•
No color indicator
: tire pressure is above
the threshold for a low inflation pressure
warning.
•
Yellow
: low tire pressure. Stop and check/
reinflate the tire(s) as soon as possible.
•
Red
: inflation pressure is very low. Stop
immediately and check/reinflate the tire(s).
•
When no tire pressure values or updated tire
pressure values are shown then system has
not learned the tire pressure values. It might
be necessary to drive at a speed of at least
20 mph (30 km/h) for several minutes.
•
If the TPMS symbol (telltale) flashes for
approx. 1 minute then glows steadily, and the
message
Tire pressure system Service
required
is displayed: this indicates that the
system is not functioning correctly. Have it
checked by a trained and qualified Volvo
service technician.
Please note that the sample tire pressures
shown in the illustration are in bar. The unit of
measure can be changed (e.g., to pound per
scare inch (psi) in the center display's Settings
menu, under
System Units Tire Pressure
.
Tire Pressure Monitoring System settings
The unit of measure for tire inflation pressure can
be changed in the center display's Top view by

When low tire pressure has been detected, a
message will be displayed in the instrument
panel and the Tire Pressure Monitoring System
symbol will illuminate.
Symbol Explanation
Check and reinflate the tire(s)
when the TPMS symbol illuminates
and a message is displayed.
1. Use a tire pressure gauge to check the infla-
tion pressure of the under-inflated tire(s).
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard located on
the driver's side B-pillar (the structural mem-
ber at the side of the vehicle, at the rear of
the driver's door opening).
3. In some cases, it may be necessary to drive
the vehicle for several minutes at a speed of
at least 20 mph (30 km/h) to erase the
TPMS telltale warning and the text message.
Please be aware that the TPMS telltale
warning will not go out until the low tire pres-
sure has been corrected.
