tire will be displayed on the multi-
information display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or
more, registration can be com-
pleted by driving for a long time.
However, if registration does not
complete after driving for 1 hour or
more, perform the procedure again
from the beginning.
7Initialize the tire pressure
warning system. ( P.599)
■When registering ID codes
●ID code registration is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performin g ID code regis-
tration, make sure that no wheels
with tire pressur e warning valve
and transmitters installed are near
the vehicle.
●Make sure to initialize the tire
pressure warning system after
registering the ID codes. If the
system is initializ ed before regis-
tering the ID codes, the initialized
values will be invalid.
●ID codes can be registered by
yourself, but depending on the
driving conditions and driving
environment, registration may
take some time to complete.
●As the tires will be warm when
registration is completed, make
sure to allow the tires to cool
before performing initialization.
■Canceling ID code registration
●To cancel ID code registration
after it has been started, turn the
power switch to OFF before driv-
ing the vehicle. If the vehicle is
driven after ID code registration is
started, to cancel registration, per-
form the ID code registration start
procedure again and turn the
power switch to OFF before driv-
ing.
●If ID code registration has been
canceled, the tire pressure warn-
ing light will blin k for approxi-
mately 1 minute when the power
switch is turned to ON and then
illuminate. The tire pressure warn-
ing system will be operational
when the tire pressure warning
light turns off.
●If the warning lig ht does not turn
off even after several minutes
have elapsed, ID code registration
may not have been canceled cor-
rectly. To cancel registration, per-
form the ID code registration start
procedure again and then turn the
power switch to OFF before driv-
ing.
■If ID codes are not registered
properly
●In the following situations, ID code
registration may take longer than
usual to be completed or may not
be possible. Normally, registra-
tion completes within approxi-
mately 30 minutes.
If ID code registration is not com-
plete after driving for approxi-
mately 30 minutes, continue
driving for a while.
• Vehicle is not pa rked for approxi-
mately 20 minutes or more before
driving
• Vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi- cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f your vehicle
over those of other vehicles
• Wheel with tire p ressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete
after driving for 1 hour or more, per-
form the ID code registration proce-
dure again from the beginning.
●If the vehicle is reversed during
registration, the data up to that

point is reset, so perform the reg-
istration procedure again from the
beginning.
●In the following situations, ID code
registration will not be started or
was not completed properly and
the system will not operate prop-
erly. Perform the ID code registra-
tion procedure again.
• If, when attempting to start ID code registration, the tire pressure
warning light does not blink slowly
3 times.
• If, when the vehicle has been driven for about 20 minutes after
performing ID co de registration,
the tire pressur e warning light
blinks for approxi mately 1 minute
and then illu minates.
If the ID codes cannot be registered
even when performing the above
procedure, contact your Toyota
dealer.
The recommended cold tire
inflation pressure and tire size
are displayed on the tire and
loading information label.
( P.690)
Tire inflation pressure
Make sure to maintain the
proper tire inflation pres-
sure. Tire inflation pressure
should be checked at least
once per month. However,
Toyota recommends that
tire inflation pressure be
checked once every two
weeks. ( P.690)
Checking the specified
tire inflation pressure

6067-3. Do-it-yourself maintenance
Tire valve
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 incorrec t tire inflation
pressure may resul t 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 judge 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 vehicle is balanced.

Maintenance and care
When replacing wheels, care
should be taken to ensure that
they are equivalent to those
removed in load capacity, diam-
eter, rim width and inset
*.
Replacement wheels are avail-
able at your Toyota dealer.
*: Conventionally referred to as off- set.
Toyota does not recommend
using the following:
 Wheels of different sizes or
types
 Used wheels
 Bent wheels that have been
straightened
■When replacing wheels (vehi-
cles with tire p ressure warning
system)
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 pres-
sure. Whenever wheels are
replaced, tire pressure warning
valves and transmitters must be
installed. ( P.593, 608)
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
●Greater possibilit y of tire dam-
age while driving (due to road
hazards, expansion joints,
sharp edges in the road, etc.)
NOTICE
■When inspecting and adjust-
ing 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.
Wheels
If a wheel is bent, cracked or
heavily corroded, it should
be replaced. Otherwise, the
tire may separate from the
wheel or cause a loss of
handling control.
Wheel selection

6087-3. Do-it-yourself maintenance
Use only Toyota wheel nuts
and 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 i nner tube in a
leaking wheel which is designed
for a tubeless 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, 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 cau se the tire to
leak air during driving, possibly
causing an accident.
NOTICE
■Replacing tire pressure warn-
ing valves and transmitters
(vehicles with tire pressure
warning system)
●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 additio n, make sure to
purchase your tire pressure
warning valves and transmit-
ters at your To yota dealer.
●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.
