When holding a tire with Selectable Color Trim (if equipped)

Replacing a flat 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. ●
Failure to follow these precautions could cau se 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, 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 76 ft•lbf (103 N•m,
10.5 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. ●
Observe the following precautions. (RX450hL)
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.
• Lower the spare tire completely to the ground before removing it from under the
vehicle.■
Replacing a flat tire for vehicles with power back door
In cases such as when replacing tires, make sure to turn off the power back door main
switch ( → P. 112). Failure to do so may cause the back door to operate unintentionally if
the power back door switch is accidentally touched, re sulting 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 tire
to drop, possibly causing injury.
