General  information
Your vehicle is equipped with tires according  to the vehicle's tire information placard  on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver's door opening), or on the inside of the fuel filler  door on
Canadian models.
The tires have good road holding characteristics and  offer  good handling on dry and  wet  surfaces. It should be  noted
however  that the tires have been developed to give these features on snow/ice-free surfaces.
Certain  models are equipped with "all-season"  tires, which  provide a  somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season"  rating. However, for optimum road holding on icy or snow-
covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be  sure that the new tires are the same size designation, type (radial)  and  preferably from  the

Tire Pressure Monitoring System (TPMS)  - option on certain U.S. models only  
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 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.
ProCarManuals.com 

When low inflation pressure is detected, TPMS will light up the tire pressure warning light () 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.
When the tire pressure monitoring  system warning light is on, one  or more of your tires is significantly under-inflated.
You should stop and  check your tires as soon as possible, and  inflate them to the proper pressure as indicated on the
vehicle's tire information placard.
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. Each tire,
including the spare, should be  checked monthly when cold and  set to the recommended inflation pressure as specified
in the vehicle placard  and  owner's  manual.
NOTE:  TPMS indicates low tire pressure but does not replace  normal tire maintenance. For information on correct tire
pressure, please refer  to the table  on page 101
, 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:
1. Use a  tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard  or the table  on page 101
).
3. Drive the car for at least one  minute 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 tires  
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, for example, winter wheels/tires are used that are not equipped with TPMS sensors,  the message TIRE PRESSURE
SYSTEM  SERVICE REQUIRED will be  displayed after the car has been driven for several minutes at approximately
35 mph (50 km/h) or faster. 
This message will remain on until wheels with TPMS sensors  are mounted on the vehicle and  it has been driven for at
least one  minute at a  speed of 20 mph (30 km/h) or faster. 
TPMS valves can be  fitted on winter wheels or full-size spare wheels/tires. Consult your Volvo retailer.
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.
pg. 103 Wheels and tires
Self supporting run flat  tires (option)
Certain  models equipped with the Tire Pressure Monitoring System  (TPMS) can also be  equipped with self  supporting
ProCarManuals.com 

run flat tires.
Tires of this  type have specially reinforced sidewalls that make it possible to continue  driving in the event of a  drop in
inflation pressure. Tires of this  type are mounted on special rims.
NOTE: Self supporting run flat tires are only available in conjunction with TPMS.
If a  self  supporting run flat tire should lose inflation pressure, the yellow TPMS warning symbol  (
) in the
instrument panel lights up to alert the driver, and  a  message will be  shown in the text window in the instrument panel.
If this  occurs, reduce vehicle speed to a  maximum of 50 mph (80 km/h). The vehicle can be  driven approximately 50
miles (80 km), or somewhat farther if the vehicle is not heavily  loaded. The tire should be  replaced  as soon as
possible.
Hard braking and  sudden steering maneuvers should be  avoided.
In certain cases, it may be  difficult to see which  self  supporting run flat tire is defective. To determine which  tire is
damaged, check the inflation pressure of all four tires.
WARNING!
• Only specially trained persons should mount self  supporting run flat tires. 
• If self  supporting run flat tires are mounted, the vehicle must  be  equipped with a  Tire Pressure Monitoring System.
• After a  low pressure warning has been displayed, do not exceed 50 mph (80 km/h). 
• Avoid severe cornering and  hard braking, and  minimize the distance traveled before replacing the self  supporting
run flat tire. 
• Self supporting run flat tires cannot be  repaired. They must  be  replaced  if damaged or punctured.

Tire designations
Federal law  mandates that tire manufacturers place standardized information on the sidewall of all tires (see the
illustration).
The following information is listed on the tire sidewall:
The tire designation (the following figures are examples of a  tire designation):

CAUTION!
The car must  not be  driven with wheels of different  dimensions or with a  spare tire other than the one  that came with
the car. The use of different  size wheels can seriously damage your car's transmission.

Changing wheels  
The spare wheel is located under the carpet  on the trunk floor.  The jack and  crank are secured in the wheel recess.  
There are two jack attachment points  on each side of the car.
To change a wheel:
 Engage the parking brake.
 Put the gear selector in (P)ark.
 Remove the wheel cap (where applicable)  using the lug wrench  in the tool bag.
 With the car still  on the ground, use the lug wrench  to loosen the wheel bolts  1/2 -1 turn by exerting downward
pressure. Turn  the bolts  counterclockwise to loosen.

Vehicle loading
The tires on your Volvo should perform to specifications at all normal loads when inflated as recommended on the tire
information label.  The label  is located on the inside of the fuel filler  door and  lists vehicle design limits. Do not load
your car beyond  the load limits indicated.
WARNING!
Improperly inflated tires will reduce tire life, adversely affect vehicle handling and  can possibly lead to failure
resulting in loss of vehicle control without prior  warning.
