Volvo XC90: Wheels and tires / Adjusting tire pressure
Tire pressure decreases over time, which is normal. The tire pressure must
therefore be adjusted to maintain the recommended tire pressure.
Use the recommended inflation pressure for cold tires to help maintain good tire
performance and even wear.
NOTE
To help prevent incorrect inflation pressure, pressure should be checked when
the tires are cold. The tires are considered to be cold when they have reached the
same temperature as the ambient temperature (about 3 hours after the vehicle was
last driven). After driving for a few kilometers, the tires will warm up and the
pressure will increase.
- Remove the valve cap from the tire and press the air pressure gauge firmly
onto the valve.
- Inflate the tire to the correct inflation pressure; see the tire pressure
placard on the driver's side B pillar for recommended pressures for factory-mounted
tires.
- Screw the valve cap back on.
NOTE
- After inflating a tire, always replace the valve cap to help prevent
valve damage caused by gravel, dirt, etc.
- Use plastic valve caps only. Metal caps could corrode and become
difficult to remove.
- Visually inspect the tire to make sure there are no nails or other embedded
objects that could puncture the tire and cause air leakage.
- Check the sidewalls to make sure there are no gouges, cuts, bulges or other
irregularities.
- Repeat this procedure for each tire, including the spare tire1.
NOTE
If you have overfilled the tire, release air by pushing on the metal stem
in the center of the valve. Then recheck the pressure with your tire gauge.
Some spare tires require higher inflation pressure than the other tires.
Consult the tire inflation pressure table or the inflation pressure decal.
1 Not available on all models.
Correct inflation pressure helps improve driving stability, save fuel and
increase the service life of the tires.

Other information:
The electrical functions in the vehicle drain the battery to varying degrees.
Avoid using ignition mode II when the engine is switched off. Use ignition mode
I instead, as this uses less electrical current.
Note that certain accessories may also drain power from the electrical system...
The first time certain services and apps are started, a pop-up window with
the heading Terms and conditions and Data sharing may open.
The aim is to inform the user about Volvo's terms of use and data sharing policy.
