CAUTION
Replacing light bulbs
Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
The bulbs become very hot and may cause burns.
Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
Fully install light bulbs and any parts used to secure them. Failure to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
Vehicles with discharge headlights:
While the headlights are turned on, and
for a short time after they have been
turned off, metal components at the rear
of the headlight assembly will be
extremely hot. To prevent burns, do not
touch these metal components until you
are certain they have cooled down.

CAUTION
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 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,
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 or repairer, or another duly qualified and equipped profes-
sional.
