Tire Pressure Monitoring System (TPMS)

* Option/accessory, for more information, see Introduction.327
NOTE
• If you change to tires with a different recommended inflation pressure, theTPMS system must be recalibrated tothese tires. On U.S. models, this mustbe done by a trained and qualifiedVolvo service technician. On Canadianmodels, see the following section"Recalibrating TPMS."
• If a tire is changed, or if the TPMS sen-sor is moved to another wheel, thesensor's seal, nut, and valve coreshould be replaced.
• When installing TPMS sensors, thevehicle must be parked for at least15 minutes with the ignition off. If thevehicle is driven within 15 minutes, aTPMS error message will be displayed.
Recalibrating TPMS (Canadian models only)*
In certain cases, it may be necessary to reca- librate TPMS to conform to Volvo's recom-mended tire inflation pressures (see the infla-tion pressure table on page 307), for exam-ple, if higher inflation pressure is necessarywhen transporting heavy loads, etc. This is done in the vehicle's menu system. See page 199 for a description of the menusystem. To recalibrate:
1. Switch off the engine.
2. Inflate the tires to the desired pressure
and put the ignition in mode I or II (see
page 87 for additional information).
3. Press the MY CAR key in the center con-
sole control panel and select
Settings
Car settingsTyre pressure
4. Press OK/MENU , select Calibrate tyre
pressure and press OK/MENU again.
5. Drive the vehicle at a speed above 25 mph (40 km/h) continuously for at least 10 minutes.
> When the calibration message is nolonger displayed, TPMS has been recalibrated to the new inflation pres-sure.
Activating/deactivating TPMS
(Canadian models only)*
1. Switch off the engine.
2. Put the ignition in mode I or II (see page
87 for additional information).

sole control panel and select

4. Select Tyre pressure system and press
OK/MENU to turn the system on or off.
Self-supporting run flat tires (SST)*
Self-supporting run flat tires are available as optional equipment. The vehicle must beequipped with the Tire Pressure MonitoringSystem (TPMS) if tires of this type are instal-led. Tires of this type have specially reinforced sidewalls that make it possible to continuedriving to a limited extent even though the tirehas lost some or all of its inflation pressure.These tires are mounted on special rims (nor-mal tires can also be mounted on these rims). If an SST tire loses inflation pressure, the yel- low TPMS symbol illuminates in the instru-ment panel and a text message is also dis-played. If this happens, reduce speed to notmore than 50 mph (80 km/h). The tire shouldbe replaced as soon as possible. Drive carefully; it may be difficult to determine which tire is damaged. To find the damagedtire, check the inflation pressure in all fourtires.
