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 performing ID code regis-

tration, make sure that no wheels 

with tire pressure 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 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.

■

Canceling ID code registration

●

To cancel ID code registration 

after it has been started, turn the 

engine switch off before driving 

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 

engine switch off before driving.

●

If ID code registration has been 

canceled, the tire pressure warn-

ing light will blink for approxi-

mately 1 minute when the engine 

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 light does not turn 

off even after several minutes 

have elapsed, ID code registration 

may not have been canceled cor-

rectly. To cancel registration, per-

404

form the ID code registration start 

procedure again and then turn the 

engine 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, registration com-

pletes within approximately 30 min-

utes.

●

Vehicle is not parked 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

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 code registration, 

the tire pressure warning light 

blinks for approximately 1 minute 

and then illuminates.

If the ID codes cannot be registered 

even when performing the above 

procedure, contact your Toyota 

dealer.

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.

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

■

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.

6-3. Do-it-yourself maintenance

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

●

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.

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.398)

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.

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.
