■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
retailer or Toyota authorized
repairer, or any reliable repairer 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 pres-
sure warning valves and trans- mitters
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 retailer or Toyota authorized repairer, or any
reliable repairer or other qualified ser-
vice 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.304)

engine switch ON and then turn
the engine switch off.
■If you press the tire pressure warn-
ing reset switch accidentally
If initialization is performed, adjust the
tire inflation pressure to the specified
level and initialize the tire pressure warning system again.
■Initialization procedure
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initialization, it
is not necessary to press the reset switch again as initialization will
restart automatically when the engine
switch has been turned to ON for the
next time.
●If you accidentally press the reset
switch when initialization is not neces- sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization again.
■When initialization of the tire pres-
sure 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 syst em will not oper- ate properly. If repeated attempts to
record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or
any reliable repairer.
●When operating the tire pressure
warning reset switch, tire pressure warning light does not blink 3 times.
●After carrying out the initialization pro-cedure, the tire pressure warning light
blinks for 1 minute then stays on after
driving for 10 minutes.
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 regis-
ter the ID code. Have the ID code

■Registering ID codes
The ID codes of the tire pressure warn- ing 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.
In addition to the set of tire pressure
warning system sensor ID codes initially registered to the vehicle, a second set of
ID codes can be registered.
A second set of tire pressure warning system sensor ID codes can be regis-
tered at your Toyota dealer or repairer,
or another duly qualified and equipped professional. When 2 sets of ID codes
have been registered, either ID code set
can be selected.

is in contact with the jack point.
4 Raise the vehicle until the tire is
slightly raised off the ground.
5 Remove all the wheel nuts and
the tire.
When resting the tire on the ground,
place the tire so that the wheel design
faces up to avoid scratching the wheel surface.
1 Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel contact
surface, the wheel nuts may loosen
while the vehicle is in motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.

■When installing the tire
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 seri-
ous accident. Remove any oil or
grease from the wheel bolts or wheel nuts.
●Have the wheel nuts tightened with a torque wrench to 120 N•m (12.2
kgf•m, 89 ft•lbf) as soon as possible
after changing wheels.
●Do not attach a heavily damaged
wheel ornament, as it may fly off the wheel while the vehicle is moving.
●When installing a tire, only use wheel nuts that have been specifi-
cally designed for that wheel.
●If there are any cracks or deforma-
tions in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.

■Effects of incorrect tire inflation
pressure
Driving with incorrect tire inflation pres-
sure 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 drivetrain
If a tire needs frequent inflating, have it
checked by any authorized Toyota retailer or Toyota authorized repairer, or
any reliable repairer.
■Instructions for checking tire infla-
tion 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 appearance.
●It is normal for the tire inflation pres-
sure 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
balanced.Tire inflation pressure
Make sure to maintain proper
tire inflation pressure. Tire
inflation pressure should be
checked at least once per
month. However, Toyota rec-
ommends that tire inflation
pressure be checked once
every two weeks.
WA R N I N G
■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 dam-
age
●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.
