When inflating your tires
When putting air into your tires (such as at a gas station or in your
garage), the Tire Pressure Monitoring System may not respond
immediately to the air added to your tires. Here are the details:
• The tire pressure sensors mounted in your wheels updates your
vehicle with tire pressure information only once every minute,
therefore it may take up to two minutes of driving over 20 mph (32
km/h) for the light to turn OFF after you have filled your tires to the
recommended tire pressure.
• If your vehicle has been parked for over 30 minutes, the sensors go
into a low power mode to conserve battery life and therefore only
transmit about once every 6 hours. If you inflate your tires under
these conditions, it may take up to two minutes of driving over 20
mph (32 km/h) for the light to turn OFF after you have filled your
tires to the recommended tire pressure.
For these reasons, the low tire pressure warning light is NOT a
substitute for using an accurate tire gauge when checking and filling
your tires.
How temperature affects your tire pressure
The Tire Pressure Monitoring System (TPMS) monitors tire pressure in
each pneumatic tire. The pressure in each tire is dependent upon several
factors, one of them being the contained air temperature (temperature of
the air inside the tire). As the contained air temperature increases, the
