Maintenance and care
●Make sure to initialize the tire
pressure warning system after
registering the ID codes. If the
system is initialized 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, select
“Identifying Each Wheel & Posi-
tion” on the multi-information dis-
play and press and hold “OK”
again.
●If ID code registration has been
canceled, the tire pressure warn-
ing light will blink for approxi-
mately 1 minute when the power
switch is turned to ON and then
illuminate. The tir e pressure warn-
ing system will be operational
when the tire pressure warning
light turns off.
●If the warning light does not turn
off even after se veral minutes
have elapsed, ID code registration
may not have bee n canceled cor-
rectly. To cancel registration, per-
form the ID code registration start
procedure again and then turn the
power switch off before driving.
■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 p erform 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 attempt ing to start ID
code registration, the tire pressure
warning light does not blink slowly
3 times.
• If, when the veh icle has been
driven for about 20 minutes after
performing ID code registration,
the tire pressure warning light
blinks for approximately 1 minute
and then illuminates.

Maintenance and care
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 b y 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.
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 possibi lity 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 no t installed, dirt
or moisture may get into the valve
and cause an air leak, resulting in
decreased tire inflation pressure.

4406-3. Do-it-yourself maintenance
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
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.427, 441)
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
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 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 cracke d or deformed
wheels.
Doing so could cause the tire to
leak air during driving, possibly
causing an accident.

Maintenance and care
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).
 Vehicles with 17-inch or 18-
inch tires: 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. 1
Turn the power switch off.
2 Open the glove box and slide
off the damper.
3 Push in each side of the
glove box to disconnect the
claws, and then slowly and
fully open the glove box while
supporting it.
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
vehicle.
Tire pressure warning valves
and transmitters may not work
properly with non-genuine
wheels.
