WARNING
■When installing the tire
Failure to follow these precautions could 
cause the wheel nuts to loosen and the 
tire to 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, lead-
ing 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 103.3 ft•lbf (140 
N•m, 14.3 kgf•m) soon as possible 
after changing wheels.
●Do not attach a heavily damaged 
wheel ornament, 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 
holes of the wheel, have the vehicle 
inspected by your  Lexus dealer.
■After using the tools
Before driving, make sure all the tools are 
stored securely in place. Failure to do so 
may cause injury in case of a collision or 
sudden braking.
