5-2. Steps to take in an emergency CAUTION n Replacing a flat tire Observe the following precautions to reduce the risk of death or serious injury: l Never use oil or grease on the wheel bolts or wheel nuts. Oil and grease may cause the wheel nuts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel nuts to loosen and the wheel may fall off, causing a serious accident. Remove any oil or grease from the wheel bolts or wheel nuts. l Have the wheel nuts tightened with a torque wrench to 103.3 ft•lbf (140 N•m, 14.3 kgf•m) as soon as possible after changing wheels. Failure to follow these precautions could cause the nuts to loosen and the wheel may fall off, which could lead to an accident causing death or serious injury. NOTICE n Do not drive the vehicle with a flat tire. Do not continue driving with a flat tire. Driving even a short distance with a flat tire can damage the tire and the wheel beyond repair. n When closing the trunk 5 Do not leave the luggage mat hook hooked on the edge of the trunk. The luggage mat may get damaged. When trouble arises n When replacing the tires When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Lexus dealer as the tire pressure warning valve and transmitter may be damaged if not handled correctly. n To avoid damage to the tire pressure warning valves and transmitters When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly.
