7-3. Do-it-yourself maintenance

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. 662)

●

Vehicles with the multi-informa-
tion display type B: The tire
pressure detected by the tire
pressure warning system can
be displayed on the multi-infor-
mation display.

◆

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. (



P. 604)

◆

Initializing the tire pressure warning system

■

The tire pressure warning system must be initialized in the fol-
lowing circumstances:

●

When changing the tire size.

●

When rotating the tires.

●

When the tire inflation pressure is changed such as when chang-
ing load weight.

●

After registering the ID codes. (



How to initialize the tire pressure warning system

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

Initialization cannot be performed while the vehicle is moving.

Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (



P. 761)

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.

Turn the engine switch to the “ON” position (vehicles without a
smart entry & start system) or IGNITION ON mode (vehicles with
a smart entry & start system).

Press and hold the tire pres-
sure warning reset switch
until the tire pressure warn-
ing light blinks 3 times.

Vehicles with the multi-informa-
tion display type B: “- -” will be
displayed for inflation pressure
of each tire on the multi-informa-
tion display while the tire pres-
sure warning system determines
the position of each tire. When
position of each tire is deter-
mined, the inflation pressure of
each tire will be displayed on the
multi-information display.

Drive the vehicle at approximately 40 km/h (25 mph) or more for
approximately 10 to 30 minutes.

Vehicles with the multi-information display type B: When initialization is
complete, the inflation pressure of each tire will be displayed on the
multi-information display.

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. When registering
the ID codes, perform the following procedure:

■

How to register the ID codes

Turn the engine switch to the “ON” position (vehicles without a
smart entry & start system) or IGNITION ON mode (vehicles with
a smart entry & start system).

Press the tire pressure warn-
ing reset switch briefly 3
times in succession.

The tire pressure warning light
blinks slowly 3 times.
The change wheel set mode is
activated and registration is
started.
Vehicles with the multi-informa-
tion display type B: “--” is dis-
played for inflation pressure of
each tire on the multi-informa-
tion display.
Then, the tire pressure warning
light blinks rapidly for approxi-
mately 1 minute and stays on.

Drive the vehicle at approximately 40 km/h (25mph) or more for
approximately 10 to 30 minutes.

Vehicles with the multi-information display type B: When registration is
completed, the tire pressure warning light will go off and the inflation
pressure of each tire will be displayed on the multi-information display.

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 retailer or Toyota
authorized repairer, or any reliable repairer.

■

Replacing tires and wheels (vehicles with the tire pressure warning sys-
tem)

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 the tire pressure
warning 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.

■

If the tread on snow tires wears down below 4 mm (0.16 in.)

The effectiveness of the tires as snow tires is lost.

■

Situations in which the tire pressure warning system may not operate
properly (vehicles with the 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.
• An auxiliary-supported run-flat tire is 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 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.

• If tires not equipped with the tire pressure warning valves and transmit-

ters are used.

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

registered in the tire pressure warning computer.

: Vehicles with the spare tire only

●

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.

■

Warning performance of the tire pressure warning system (vehicles with
the tire pressure warning system)

The warning of the tire pressure warning system will change in accordance
with the conditions under which it was initialized. For this reason, the system
may give a warning even if the tire pressure does not reach a low enough
level, or if the pressure is higher than the pressure that was adjusted to when
the system was initialized.

■

The initialization operation (vehicles with the tire pressure warning sys-
tem)

●

Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.

●

If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart entry & start system) or off (vehicles with a smart
entry & start system) during initialization, it is not necessary to press the
reset switch again as initialization will restart automatically when the engine
switch has been turned to the “ON” position (vehicles without a smart entry
& start system) or IGNITION ON mode (vehicles with a smart entry & start
system) for the next time.

●

If you accidentally press the reset switch when initialization is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold, and conduct initialization again.

●

Vehicles with the multi-information display type B: While the position of each
tire is being determined and the inflation pressures are not being displayed
on the multi-information display, if the inflation pressure of a tire drops, the
tire pressure warning light will come on.

■

When initialization of the tire pressure warning system has failed (vehi-
cles with the tire pressure warning system)

●

Do not move the vehicle backward during initialization. Initialization is
started again from the beginning and it may take longer than usual.

●

Initialization may take longer to complete if the vehicle is driven on an
unpaved road.
When performing initialization, drive on a paved road if possible. Depending
on the driving environment and condition of the tires, initialization will be
completed in approximately 10 to 30 minutes.
• If initialization is not complete after driving approximately 30 minutes,

continue driving for a while.

• If initialization is not complete after driving approximately 1 hour, park the

vehicle in a safe place for approximately 20 minutes. Then drive straight
(with occasional left and right turns) at approximately 40 km/h (25 mph)
or more

for approximately 10 to 30 minutes.

If initialization is still not complete, have the vehicle inspected by any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.

: Except when making a left/right turn

●

In the following situations, the tire inflation pressure will not be recorded and
the system will not operate properly. Perform initialization again.
• When operating the tire pressure warning reset switch, the tire pressure

warning light does not blink 3 times.

• After performing initialization, the tire pressure warning light blinks for 1

minute then stays on after driving for about 20 minutes.

■

When registering ID codes (vehicles with the tire pressure warning sys-
tem)

●

Initialize the tire pressure warning system after ID code registration. Initial-
ization is disabled if the system was initialized before registration.

●

After ID code registration, the tires are hot by driving. Initialize the tire pres-
sure warning system after the tires become cold.

■

Canceling the change wheel set mode (vehicles with the tire pressure
warning system)

●

If turning the engine switch to the “LOCK” position (vehicles without a smart
entry & start system) or off (vehicles with a smart entry & start system) when
in the change wheel set mode before driving, the change wheel set mode is
canceled.

●

After driving when in the change wheel set mode, the change wheel set
mode cannot be canceled. To cancel the mode, perform the procedure for
ID code registration again and turn the engine switch to the “LOCK” position
(vehicles without a smart entry & start system) or off (vehicles with a smart
entry & start system) before driving.

●

If the change wheel set mode is canceled, the ID codes that have already
been registered are communicated. When communication is finished, the
tire pressure warning light will turn off.
