NOTICE
■
Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
●When removing or fitting the wheels, ti res or the tire pressure warning
valves and transmitters, contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional as the tire pressure
warning valves and transmitters may be damaged if not handled correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.
■ To avoid damage to the tire pressure warning valves and transmitters
When a tire is repaired with liquid sealants, the tire pressure warning valve
and transmitter may not operate properly. If a liquid sealant is used, contact
any authorized Toyota dealer or re pairer, or another duly qualified and
equipped professional or other qualified service shop as soon as possible.
After use of liquid sealant, make sure to replace the tire pressure warning
valve and transmitter when repairing or replacing the tire. ( →P. 343)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot holes.
These conditions may cause losses in tire air pressure, reducing the cush-
ioning ability of the tires. In additi on driving on rough roads may cause dam-
age to the tires themselves, as well as the vehicle’s wheels and body.

WARNING
■
Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur which
could lead to an accident resulting in death or serious injury:
●Excessive wear
● Uneven wear
● Poor handling
● Possibility of blowouts resulting from overheated tires
● Air leaking from between tire and wheel
● Wheel deformation and/or tire damage
● Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
NOTICE
■When inspecting and adjusting tire pressure
Be sure to reinstall the tire valve caps.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

■
When replacing wheels
The wheels of your Toyota are equipped with tire pressure warning valves
and transmitters that allow the tire pressure warning system to provide
advance warning in the event of a loss in tire inflation pressure. Whenever
wheels are replaced, the tire pressure warning valves and transmitters must
be installed. ( →P. 343)
WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommended in the
Owner’s Manual, as this may result in loss of handling control.
● Never use an inner tube in a leaking wheel which is designed for a tube-
less tire. Doing so may result in an accident, causing death or serious
injury.
■ When installing the wheel nuts
●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 an acci-
dent and resulting in death or serious injury. Remove any oil or grease
from the wheel bolts or wheel nuts.
● Be sure to install the wheel nuts with
the tapered ends facing inward. Install-
ing the nuts with the tapered ends fac-
ing outward can cause the wheel to
break and eventually cause the wheel
to come off while driving, which could
lead to an accident resulting in death or
serious injury.

NOTICE
■
Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement ma y affect the tire pressure warning
valves and transmitters, make sure to have tires serviced by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped pro-
fessional.
● Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly with
non-genuine wheels.

After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. ( →P. 372)
● If the replaced fuse blows again, have the vehicle inspected by any
authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage to the vehicle, and possibly a fire or
injury.
●Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
● Do not modify the fuse or the fuse box.

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 t he 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 the light bulbs and any parts used to secure them. Failure to
do so may result in heat damage, fire, or water entering a light unit. This
may damage the light or cause condensation to build up on the inner side
of the lens.
■ When changing the rear fog light or back-up lights
Stop the engine and wait until the exhaust pipes have cooled down suffi-
ciently. The lights are located near the exhaust pipe and touching a hot
exhaust pipe can cause burns.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
