'04 4Runner_U (L/O 0409) CAUTION When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under- inflated. You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle's tire information placard. Driving on a significantly under- inflated tire causes the tire to overheat and can lead to tire failure. Under- inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner's manual. For vehicles sold in U.S.A. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 188 2004 4RUNNER from Sep.
