Tire Pressure Monitoring System (TPMS) - U.S. models
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
the vehicle is moving at a speed of approximately 20 mph (30 km/h) or faster, these sensors transmit inflation pressure
data to a receiver located in the vehicle.USA - FCC ID: MRXTG315AM04

This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
1On certain models, the FCC code is MRXTG315AM04
When low inflation pressure is detected, TPMS will light up the tire pressure warning light () (also referred to as a
telltale) in the instrument panel, and will display a message in the text window. The wording of this message is
determined by the degree of inflation pressure loss.
NOTE
If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE PRESS
SYST SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire pressure monitoring system (TPMS) that
illuminates a low tire pressure telltale when one or more of your tires is significantly under-inflated. Accordingly,
when the low tire pressure telltale illuminates, you should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and
stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the driver's responsibility to
maintain correct tire pressure, even if under-inflation has not reached the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating
properly. The TPMS malfunction indicator is combined with the low tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approximately one minute and then remain continuously illuminated. This
sequence will continue upon subsequent vehicle start-ups as long as the malfunction exists. When the malfunction
indicator is illuminated, the system may not be able to detect or signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels
on the vehicle that prevent the TPMS from functioning properly. Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your vehicle to ensure that the replacement or alternate tires and wheels allow
the TPMS to continue to function properly.

NOTE
TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the tables on pages 160 and 161
, or consult your Volvo retailer.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
Use a tire pressure gauge to check the inflation pressure of all four tires.
Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the tables on pages 160 and 161).
Drive the vehicle for several minutes at a speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning light will go out.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
Changing wheels with TPMS
Please note the following when changing or replacing the factory installed TPMS wheels/tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will be
displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
CAUTION
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.

Glossary of tire terminology
Tire suppliers may have additional markings, notes or warnings such as standard load, radial tubeless, etc.
Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommended inflation
pressure, and the maximum weight the vehicle can carry.
Tire Identification Number (TIN): A number on the sidewall of each tire providing information about the tire
brand and manufacturing plant, tire size and date of manufacturer.
Inflation pressure: A measure of the amount of air in a tire.
Standard load: A class of P-metric or Metric tires designed to carry a maximum load at 35 psi [37 psi (2.5 bar) for
Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability.
Extra load: A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar)
for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying
capability.
kPa: Kilopascal, a metric unit of air pressure.
PSI: Pounds per square inch, a standard unit of air pressure.
B-pillar: The structural member at the side of the vehicle behind the front door.
Bead area of the tire: Area of the tire next to the rim.
Sidewall of the tire: Area between the bead area and the tread.
Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted on the vehicle.
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can be carried by the
tire. This rating is established by the tire manufacturer.
Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire.
This limit is set by the tire manufacturer.
Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on the type of tires
that are mounted on a vehicle at the factory. This inflation pressure is affected by the number of occupants in the
vehicle, the amount of cargo, and the speed at which the vehicle will be driven for a prolonged period. This
information can be found on the tire inflation placard(s) located on the driver's side B-pillar or on the inside of the fuel
filler door on Canadian models, and in the tire inflation table in this chapter.
Cold tires: The tires are considered to be cold when they have the same temperature as the surrounding (ambient)
air. This temperature is normally reached after the vehicle has been parked for at least 3 hours.
