Failure to follow these precautions
could cause the wheel nuts to loosen
and the tire to fall off, resulting in death
or serious injury.
• Have the wheel nuts tightened with a
torque wrench to 97 ft•lbf (131 N•m,
13.4 kgf•m), 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 your Lexus dealer.
• Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
●
In cases such as when replacing tires,
make sure to cancel the power back
door system. (
P.116) Failure to do so
may cause the back door to operate
unintentionally if the power back door
switch is accidentally touched, result-
ing in hands and fingers being caught
and injured.
