3066-3. Do-it-yourself maintenance
Use only Lexus wheel bolts and
wrenches designed for use with
your aluminum wheels.
 When rotating, repairing or chang-
ing your tires, check that the wheel
bolts are still tight after driving 621
miles (1000 km).
 Be careful not to damage the alumi-
num wheels when using tire chains.
 Use only Lexus genuine balance
weights or equivalent and a plastic
or rubber hammer when balancing
your wheels.
WARNING
●Never use an inner tube in a leaking
wheel which is designed for a tubeless
tire.
Doing so may result in an accident,
causing death or serious injury.
●Use the correct wheel bolts for the
wheels to be installed. For details, con-
tact your Lexus dealer.
■Wheel bolts
Observe the following precautions to
reduce the risk of death or serious injury:
●Do not over tighten.
●Never use oil or grease on the wheel
bolts. Oil and grease may cause the
wheel bolts to be excessively tight-
ened, leading to bolt or disc wheel
damage. In addition, the oil or grease
can cause the wheel bolts to loosen
and the wheel may fall off, causing a
serious accident. Remove any oil or
grease from the wheel bolts.
●If there are any cracks or deformations
in the wheel bolts, or if the surface
treatment becomes worn, have the
wheel bolts replaced at your Lexus
dealer. Failure to follow these precau-
tions could cause the wheel bolts to
loosen and the tire to fall off, resulting
in death or serious injury.
NOTICE
■Replacing tire pressure warning
valves and transmitters
●Because tire repair or replacement
may affect the tire pressure warning
valves and transmitters, make sure to
have tires serviced by your Lexus
dealer or other qual ified service shop.
In addition, make sure to purchase
your tire pressure warning valves and
transmitters at your Lexus dealer.
●Ensure that only genuine Lexus wheels
are used on your vehicle.
Tire pressure warning valves and trans-
mitters may not work properly with
non-genuine wheels.

12 Remove the protective tape.
■When replacing the front turn signal
lights (bulb type)
When the washer fluid filler opening is
removed with a large amount of washer
fluid contained in the washer tank, washer
fluid may spill onto the vehicle and cleaning
may be required.
WARNING
■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 buil d up on the lens.
■To prevent damage or fire
●Make sure bulbs are fully seated and
locked.
●Check the wattage of the bulb before
installing to prevent heat damage.

be tightened excessively, leading to
damage to the wheel bolts, the
threaded portion the wheel bolts install
to , or the wheel.
Also, the wheel bolts may come loose,
possibly leading to the wheel coming
off, causing a serious accident.
If oil or grease is at tached to either of
these parts, remove it.
