When registering ID codes

●

Normally, ID codes registration

can be completed within approxi-

mately 30 minutes.

●

ID code registration is performed

while driving at a vehicle speed of

approximately 25 mph (40 km/h)

or more.

■

If ID codes are not registered

easily

●

In the following situations, ID code

registration may take longer than

usual to be completed or may not

be possible.

• When the vehicle has not been

parked for approximately 20 min-

utes or more before being driven

• 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 of your vehicle

over those of other vehicles

• Wheel with tire pressure warning

valve and transmitter installed is

inside or near the vehicle

●

If the vehicle is reversed during

registration, all data collected until

then will be cleared. Perform driv-

ing again.

●

If the tire pressure warning light

does not blink 3 times when start-

ing ID code registration proce-

dure to step

, the procedure may

not have started. Perform the pro-

cedure again from the beginning.

●

If registration does not complete

after driving for 1 hour or more,

perform the ID code registration

procedure again from the begin-

ning.

●

If the ID codes cannot be regis-

tered even when performing the

above procedure, contact your

Toyota dealer.

Canceling ID code registration

To cancel ID code registration after

it has been started, select “Register

Valve / ID” again on the multi-infor-

mation display.
If ID code registration has been can-

celed, the tire pressure warning light

will turn off.
If the warning light does not turn off,

ID code registration may not have

been cancelled correctly. To cancel

registration, select “Register Valve /

ID” on the multi-information display.

Your vehicle is equipped with a
tire pressure warning system
with a function to register two
sets of ID codes. This allows for
registration of a second wheel
set, for example a winter set.
The wheel set can be changed
only if a second wheel set has
been registered to the system. If
a second wheel set has not
been registered, it will not be
possible to change to the
selected wheel set.
ID codes can be registered by
yourself.



Only a change between both
registered wheel set is possi-
ble, mixing between these
wheel sets is not supported.



While registering ID codes, it
may not be possible to
change between wheel sets
normally. Cancel registration
before changing between
wheel sets.

Tire pressure gauge

Remove the tire valve cap.

Press the tip of the tire pres-
sure gauge onto the tire
valve.

Read the pressure using the
gauge gradations.

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.

After completing the tire infla-
tion pressure measurement
and adjustment, apply soapy
water to the valve and check
for leakage.

Put the tire valve cap back

■

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 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 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

6-3. 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, the tire pressure warning

valves and transmitters must be

installed. (



P.330)

WARNING

●

Greater possibility 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.



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 tight-

ened, 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 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.
