WARNING
■When holding a tire with Selectable Color Trim (if equipped)
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes immediately after the vehicle has been driven.After the vehicle has been driven the disc wheels and the area around the brakes
will be extremely hot. Touching these area s with 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. • 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 holes of the wheel, have the vehicle inspected by any authorized Lexus dealer orrepairer, or another duly qualif ied and equipped professional.
• Do not attach a heavily damaged wheel or nament, as it may fly off the wheel while the vehicle is moving.
■Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to canceling the power back door sys- tem ( P. 115). Failure to do so may cause the back door to operate unintentionally if the power back door switch is accidentally touched, resulting in hands and fingers
being caught and injured.
Do not hold the tire by the Selectable Color
Trim. Otherwise, the Selectable Color Trim may be damaged or may fall off causing the tireto drop, possibly causing injury.

the vehicle until the area of the
puncture, if known, is positioned
at the top of the tire.
