Maintenance and care
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the power switch off during initialization, it is
not necessary to press the reset switch again as initialization will restart
automatically when the power switch has been turned to ON mode for the
next time.
●If you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance
with the conditions under which it was initialized. For this reason, the system
may give a warning even if the tire pressure does not reach a low enough
level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.
■When initialization of the tire pressure 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 operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
●When operating the initialization of the system, the tire pressure warning
light does not flash 3 times and the setting message does not appear on the
multi-information display.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minutes.
■Registering ID codes
The ID codes of the tire pressure warning valve and transmitters for two sets
of wheels can be registered.
It is not necessary to register the ID codes when replacing normal tires with
snow tires, if the ID codes for the wheels of both normal tires and snow tires
are registered beforehand.
For information about changing ID codes, ask any authorized Toyota dealer
or repairer, or another duly qualified and equipped professional.

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 makes, 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 tires (radial, bias-belted or bias-ply
tires).
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■ When initializing the tire pressure warning system
Do not initialize the tire pressure wa rning system 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
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps
● When removing or fitting the wheels, tires 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 r epairer, 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. 581)
■ Driving on rough roads
Take particular care when driving on roads with loose surfaces or potholes.
These conditions may cause losses in tire inflation pressure, reducing the
cushioning ability of the tires. In addition, driving on rough roads may cause
damage to the tires themselves, as well as the vehicle’s wheels and body.
■ If tire inflation pressure of each tire becomes low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Tire inflation pressure
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent inflating, have it checked by any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours or has not been driven
for more than 1.5 km or 1 mile, you will get an accurate cold tire inflation
pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its appear-
ance.
●It is normal for the tire inflation pressure to be higher after driving as heat is
generated in the tire. Do not reduce tire inflation pressure after driving.
●Passengers and luggage weight should be placed so that the vehicle is bal-
anced.
Make sure to maintain proper tire inflation pressure. Tire infla-
tion pressure should be checked at least once per month. How-
ever, Toyota recommends that tire inflation pressure be checked
once every two weeks. (P. 704)

Maintenance and care
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 inflation pressure
Be sure to put the tire valve caps back on.
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.

Maintenance and care
■When replacing wheels
The wheels of your vehicle 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, tire pressure warning valves and transmitters must be
installed. ( P. 581)
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 a 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.
■ Use of defective wheels prohibited
Do not use cracked or deformed wheels.
Doing so could cause the tire to leak air during driving, possibly causing an
accident.
● Be sure to install the wheel nuts with the
tapered ends facing inward. Installing
the nuts with the tapered ends facing
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.
