WARNING
■Replacing a tire
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
areas with hands, feet or other body
parts while changing a tire, etc. may
result in burns.
■Replacing a tire for vehicles with
power back door
In cases such as when replacing tires,
make sure to cancel the power back
door system ( P.122). 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.

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 76 ft•lbf (103 N•m,
10.5 kgf•m) as 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.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
■After using the tools and jack (if
equipped)
Before driving, make sure all the tools
and jack are stored securely in place.
Failure to do so may cause injury in case
of a collision or sudden braking.
