Maintenance and care
◆Registering ID codes
The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by your Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■Proper storage of the spare tire
As an improperly stored spare tire may cause damage to the wire cable
that holds it, check that the spare tire is stored properly on a daily basis.
• If the spare tire is slanted, the ho ist assembly may be stuck in the
wheel opening. If the spare tire rattles while driving, it may not be fully
raised. Lower the spare tire to the ground and make sure that the
hoist assembly is perpendic ular to the wheel opening.
• Raise the tire slowly and steadily until a click is heard and the jack handle skips.
• If the spare tire cannot be lowered, the wire cable may be severed.
Have the vehicle inspected at your Toyota dealer.
●If the stored spare tire is slanted or
causes a rattle while driving, properly
store the spare tire by following the
tire change procedure correctly
( P. 490).

The initialization operation
●Make sure to carry out in
itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the power switch to off during initializa-
tion, it is not necessary to press th e reset switch again as initialization
will restart automatically when the po wer switch has been turned to the
ON mode for the next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
■When initialization of the tire pr essure warning system has failed
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●When operating the tire pressure wa rning reset switch, the tire pressure
warning light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning
light blinks for 1 minute then stays on after driving for 20 minutes.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
●Do not mix tires of different ma kes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed ti res (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a
compact spare tire installed.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. Otherwise, the
tire pressure warning light may not come on even if the tire inflation
pressure is low, or it may come on when the tire inflation pressure is
actually normal.

Maintenance and care
■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. 438)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure 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 that indicated, or use\
any other object in place of a fuse.
● Always use a genuine Toyota fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
● Do not modify the fuses or fuse boxes.
■ Fuse box near the power control unit
Never check or replace the fuses as there are high voltage parts and wiring
near the fuse box.
Doing so may cause electric shock, resulting in death or serious injury.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer as soon as possible.
