Maintenance and care
■The tire pressure warning
system must be initialized
in the following circum-
stances:
 When the tire inflation pres-
sure is changed such as
when changing traveling
speed or load weight.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
 When rotating the tires.
 After performing the transmit-
ter ID code registration proce-
dure. ( P.409) When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.
■How to initialize the tire
pressure warning system
1 Park the vehicle in a safe
place, turn the power switch
off and wait 20 minutes or
more.
Initialization cannot be performed
while the vehicle is moving.
2Adjust the tire inflation pres-
sure to the specified cold tire
inflation pressure level.
Make sure to adjust the tire pres-
sure to the specifie d cold tire infla-
tion pressure level. The tire
pressure warning system will oper-
ate based on this pressure level.
3Start the fuel cell system.
4 Press or of the meter
control switch to select .
5 Press or to select
“Vehicle Settings” and then
press and hold .
6 Press or to select
“TPWS” and then press .
7 Press or to select “Set
Pressure”. Then press and
hold until the tire pressure
warning light starts blinking.
A message is displayed on the
multi-information di splay. Also, “--”
is displayed for inflation pressure of
NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pr essure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves, corrode the valve, and
cause sticking and air leaks.
●When replacing ti re valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.

sure warning system

Tire pressure gauge
1 Remove the tire valve cap.
2 Press the tip of the tire pres-
sure gauge onto the tire
valve.
3 Read the pressure using the
gauge gradations.
4 If the tire inflation pressure is
not at the recommended
level, adjust the pressure.
If you add too much air, press
the center of the valve to
deflate.
5 After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.
6 Put the tire valve cap back
on.
■Tire inflation pressure check
interval
You should check tire inflation pres-
sure every two weeks, or at least
once a month. Do not forget to
check the spare.
■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 your Toyota
dealer.
■Instructions for checking tire
inflation pressure
When checking tire inflation pres-
sure, 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 mile or 1.5
km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to j udge if a tire is
properly inflated based only on its
appearance.
●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.
●Never exceed the vehicle capacity
weight.
Passengers and luggage weight
should be placed so that the vehi-
cle is balanced.
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 seri-
ous 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

Use only Toyota wheel nuts
and wheel nut wrenches
designed for use with your
aluminum wheels.
 When rotating, repairing or
changing your tires, check
that the wheel nuts are still
tight after driving 1000 miles
(1600 km).
 Be careful not to damage the
aluminum wheels when using
tire chains.
 Use only Toyota genuine bal-
ance weights or equivalent
and a plastic or rubber ham-
mer when balancing your
wheels.
WARNING
■When replacing wheels
●Do not use wheels that are a dif-
ferent size from those recom-
mended 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 tubeless tire.
Doing so may result in an acci-
dent, 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, lead-
ing 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, caus-
ing an accident and resulting in
death or serious injury. Remove
any oil or grease from the wheel
bolts or wheel nuts.
■Use of defective wheels pro-
hibited
Do not use cracked or deformed
wheels. Doing so could cause the
tire to leak air during driving, pos-
sibly causing an accident.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
●Because tire repair or replace-
ment may affect the tire pres-
sure warning valves and
transmitters, make sure to have
tires serviced by your Toyota
dealer or other qualified service
shop. In addition, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your Toyota dealer.
●Ensure that only genuine Toyota
wheels are used on your vehi-
cle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.

ber (VIN) is the legal identifier
for your vehicle. This is the pri-
mary identification number for
your Toyota. It is used in regis-
tering the ownership of your
vehicle.
This number is stamped on the
top left of the instrument panel. This number is also stamped
under the right-hand front seat.
