G Warning Each tire, including the spare tire (if there is one), should be inspected at least every two weeks when they are cold and pumped to the pressure recommended by the vehicle manufacturer (see the tire and load data label on the B-pillar on the driver's side or the tire pressure table on the inside of the fuel filler flap of your vehicle, if there is one). If your vehicle has tires which are a different size to those on the tire and load data label or those specified in the tire pressure table, if there is one, you should determine the correct tire pressure for these tires. As an added safety feature, your vehicle has been equipped with a tire pressure monitor (TPMS). An indicator lamp lights up if one or more of your tires are significantly underinflated. Accordingly, when the low tire pressure indicator lamp lights up, you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes the tire to overheat and can lead to tire failure. An excessively low tire pressure also increases fuel consumption, reduces the service life of the tires and may impair the driving and braking characteristics of the vehicle. Please note that the TPMS is not a substitute for proper tire maintenance and it is the driver's responsibility to maintain correct tire pressure, even if underinflation has not reached the level at which the low tire pressure indicator lamp of the TPMS lights up. USA only: Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the system is not operating properly. The TPMS malfunction indicator is combined with the low tire pressure indicator lamp. When the system detects a malfunction, the indicator lamp will flash Z On-board computer and displays
