'05 TUNDRA_U (L/O 0408) Tire pressure warning system- The tire pressure warning system is designed to provide warning when tire inflation pressure of one or more of your tires (including the spare tire) is low. The low tire pressure warning light comes on to inform you that low tire inflation pressure may hamper driving. LOW TIRE PRESSURE WARNING LIGHT This light comes on when the ignition key is turned to the "ON" position. It goes off after a few seconds. This indicates that the tire pressure warning system is functioning properly. If the low tire pressure warning light comes on or blinks, do the following. If the warning light comes on: Stop your vehicle in a safe place as soon as possible and check that the inflation pressure of all tires (including the spare tire) is as specified on the tire and loading information label. (See "Checking tire inflation pressure" in Section 7−2.) If the warning light comes on even after tire inflation pressure adjustment, you may have a flat tire. If you have a flat tire, replace it with the spare tire. For details, see "If you have a flat tire" in Section 4. The warning light goes off a few minutes after air is put into the deflated tire. This warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by temperature. In this case, adjusting the tire pressure will turn off the warning light. Without tachometer With tachometer 200 2005 TUNDRA from Aug. '04 Prod. (OM34427U)
