Rotate the tires in the order shown.

To equalize tire wear and help extend tire life, Toyota recommends that tire
rotation is carried out approximately every 10000 km (6000 miles).
Do not fail to initialize the tire pressure warning system after tire rotation.
(vehicles with tire pressure warning system)

Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valves and transmitters to detect low tire infla-
tion pressure before serious problems arise.
If the tire pressure drops below a predetermined level, the driver is
warned by a warning light. (

→P. 572)

◆

Installing tire pressure warning valves and transmitters

When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed. 
When new tire pressure warning valves and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pressure warning system must be
initialized. Have tire pressure warning valves and transmitter ID
codes registered by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional. (

→P. 521)

Initializing the tire pressure warning system

■

The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-

ing traveling speed or load weight.

● When the tire inflation pressure is changed such as when the tire

size is changed.

● When rotating the tires.
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

Vehicles without smart entry & start system:
Park the vehicle in a safe place and turn the engine switch to the
“LOCK” position.
Vehicles with smart entry & start system:
Park the vehicle in a safe place and turn the engine switch off.

Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire inflation

pressure level. (

→P. 642)

Make sure to adjust the tire pressure to the specified cold tire inflation
pressure level. The tire pressure warning system will operate based on
this pressure level.

Vehicles without smart entry & start system: 
Turn the engine switch to the “ON” position.
Vehicles with smart entry & start system: 
Turn the engine switch to IGNITION ON mode.

Press and hold the tire pres-
sure 

warning reset switch

until the tire pressure warn-
ing light blinks slowly 3 times.

re

Vehicles without smart entry & start system: Wait for a few minutes
with the engine switch in the “ON” position and then turn the engine
switch to the “ACC” or “LOCK” position.

Vehicles with smart entry & start system: Wait for a few minutes
with the engine switch in IGNITION ON mode and then turn the
engine switch off.

◆

Registering ID codes

The tire pressure warning valve and transmitter is equipped with a
unique ID code. When replacing a tire pressure warning valve and
transmitter, it is necessary to register the ID code. Have the ID code
registered by any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.

■

When to replace your vehicle’s tires
Tires should be replaced if:

●

The treadwear indicators are showing on a tire.

●

You have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, and bulges indicating internal damage

●

A tire goes flat repeatedly or cannot be properly repaired due to the size or
location of a cut or other damage

If you are not sure, consult with any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional.

■

Replacing tires and wheels (vehicles with tire pressure warning system)
If the ID code of the tire pressure warning valve and transmitter is not regis-
tered, the tire pressure warning system will not work properly. After driving for
about 10 minutes, the tire pressure warning light blinks for 1 minute and stays
on to indicate a system malfunction.

■

Tire life
Any tire over 6 years old must be checked by a qualified technician even if it
has seldom or never been used or damage is not obvious.

■

Routine tire inflation pressure checks (vehicles with tire pressure warn-
ing system)
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your routine
of daily vehicle checks.

■

Initializing the tire pressure warning system (vehicles with tire pressure
warning system)
Initialize the system with the tire inflation pressure adjusted to the specified
level.

■

If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.

■

If you press the tire pressure warning reset switch accidentally (vehicles
with tire pressure warning system)
If initialization is performed, adjust the tire inflation pressure to the specified
level and initialize the tire pressure warning system again.

■

Situations in which the tire pressure warning system may not operate
properly (vehicles with tire pressure warning system)

●

In the following cases, the tire pressure warning system may not operate

properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment)

tire.

• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• If a window tint that affects the radio wave signals is installed.
• If there is a lot of snow or ice on the vehicle, particularly around the

wheels or wheel housings.

• If the tire inflation pressure is extremely higher than the specified level.
• If tires not equipped with tire pressure warning valves and transmitters

are used.

• If the ID code on the tire pressure warning valves and transmitters is not

registered in the tire pressure warning computer.

• If the spare tire is in a location subject to poor radio wave signal recep-

tion.

• If a large metallic object which can interfere with signal reception is put

near the spare tire.

●

Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large dis-

play, airport or other facility that generates strong radio waves or electri-
cal noise

• When carrying a portable radio, cellular phone, cordless phone or other

wireless communication device

●

When the vehicle is parked, the time taken for the warning to start or go off
could be extended.

●

When tire inflation pressure declines rapidly for example when a tire

has burst, the warning may not function.
