WARNING
■Replacing a flat tire
●Do not touch the disc wheels or the area around the brakes immediately after thevehicle has been driven.
After the vehicle has been driven the disc wheels and the area around the brakes will be extremely hot. Touching these areas wi th hands, feet or other body parts while changing a tire, etc. may result in burns.
●Failure to follow these precautions could cause the wheel nuts to loosen and the tireto fall off, resulting in death or serious injury.
• 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. • Have the wheel nuts tightened with a torque wrench to 103 N•m (10.5 kgf•m,76 ft•lbf) as soon as possible after changing wheels.
• Do not attach a heavily damaged wheel or nament, as it may fly off the wheel while the vehicle is moving.• When installing a tire, only use wheel nuts that have been specifically designed for
that wheel. • If there are any cracks or deformations in the bolt screws, nut threads or bolt holesof the wheel, have the vehicle inspected by any authorized Lexus dealer or
repairer, or another duly qualif ied and equipped professional.
