How is tire pressure checked?

Safe operation of your vehicle requires that your tires are properly inflated. Check your tire pressure everyday before driving your vehicle.
At least once a month and before long trips, inspect each tire and check the tire pressure with a tire gauge. Inflate all tires to the recommended inflation pressure. 

Inflating The Tires

Use the recommended cold inflation pressure for optimum tire performance and wear. Under-inflation or over-inflation may cause uneven tread wear patterns.

Inflate your tires to the recommended inflation pressure even if it is less than the maximum inflation pressure information found on the tire. You can find the tire label with the recommended tire inflation pressure next to the tire size on the B-pillar or the edge of the driver door.

The recommended tire inflation pressure is also found on the Safety Compliance Certification Label, affixed to either the door hinge pillar, door latch post, or the door edge that meets the door latch on the B-pillar, or on the edge of the driver door.
Failure to follow the tire pressure recommendations can cause uneven tread wear patterns and adversely affect the way your vehicle handles.

When temperature changes occur, tire inflation pressures also change. A 6°C or 10°F temperature drop can cause a corresponding drop of 7 kPa in inflation pressure. Check your tire pressure frequently and adjust them to the proper pressure which can be found on the Safety Compliance Certification Label or tire Label.

WARNING:

• Under-inflation is the most common cause of tire failures and may result in severe tire cracking, tread separation or blowout, with unexpected loss of vehicle control and increased risk of injury. Under-inflation increases sidewall flexing and rolling resistance, resulting in heat buildup and internal damage to the tire. It also may result in unnecessary tire stress, irregular wear, loss of vehicle control and accidents. A tire can lose up to half of its air pressure and not appear to be flat!
• Do not use the tire pressure displayed in the information display as a tire pressure gauge. Failure to follow this instruction could result in personal injury or death.
