How to Check

Use a good quality pocket-type gage to check tire pressure. You can't tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they're underinflated.

Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.

Check Tire Pressure System (If Equipped)

The check tire pressure system can alert you to a large change in the pressure of one tire. The system won't alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly.

The TIRE PRESSURE LOW: CHECK TIRES message will appear on the Driver Information Center (DIC) if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if:

Dmore than one tire is low,

Dthe vehicle is moving faster than 65 mph (105 km/h),

Dthe system is not yet calibrated,

Dthe tire treadwear is uneven,

Dthe compact spare tire is installed,

Dtire chains are being used, or

Dthe vehicle is being driven on a rough or frozen road.
