How to initialize the tire pressure warning system
Park the vehicle in a safe pl ace and turn the engine switch
OFF.
While the vehicle is moving, in itialization is not performed.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( P. 467)
Make sure to adjust the tire pressure to the specified cold tire
inflation pressure level. The ti re pressure warning system will
operate based on this pressure level.
Turn the engine switch to the “ON” position.
Push and hold the tire pressure
warning reset switch until the tire
pressure warning light blinks
slowly 3 times.
Wait for a few minutes with the engine switch in the “ON” posi-
tion, and then turn the engine switch to the “LOCK” position.

Registering ID codesThe 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 regi ster the ID code of tire pressure
warning valve and transmitter. Have the ID code registered by your
Toyota dealer.
■When to replace your vehicle’s tires
Tires should be replaced if:
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, or bulges indicating internal damage
●A tire goes flat repeatedly or c annot be properly repaired due to the
size or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre ssure warning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■If you push the tire pressure warning reset switch accidentally
If initialization is performed, adjust the tire in flation pressure to the speci-
fied level and initialize the tire pressure warning system again.

Maintenance and care
■When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have not b
een recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light doe s not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.
■Routine tire inflation pressure checks
The tire pressure warning system doe s not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAW R) of either the front axle or the
rear axle, whichever is greater.
■Low profile tires (models not equipped with 16-inch tires)
Generally, low profile tire s will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or tire chains
* on snowy and/or
icy roads and drive carefully at a speed appropriate for road and weather
conditions.
*: Tire chains cannot be mounted on 18-inch tires.
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. ( P. 473)

CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so
may cause damage to parts of the drive train, as well as dangerous han-
dling characteristics, which may lead to an accident resulting in death or
serious injury.
● Do not mix tires of different makes, models or tread patterns. Also, do not
mix tires of remarkably different treadwear.
●
Do not use tire sizes other than those recommended by Toyota.
● Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●
Do not mix summer, all season and winter tires.
■When initializing the tire pressure warning system
Do not push the tire pressure warnin g reset switch without first adjusting
the tire inflation pressure to the spec ified level. Otherwise, the tire pres-
sure warning light may not come on ev en if the tire inflation pressure is
low, or it may come on when the tire inflation pressure is actually normal.

■
SRS warning light
This warning light system monitors the airbag sensor assembly, front airbag
sensors, side and curtain shield airbag sensors, curtain shield airbag sen-
sors, driver's seat position sensor, driver's seat belt buckle switch, front pas-
senger occupant classification system (ECU and sensors), “AIR BAG ON”
indicator light, “AIR BAG OFF” indicator light, front passenger's seat belt
buckle switch, seat belt pretensioners and force limiters, airbags, intercon-
necting wiring and power sources. ( P. 73)
■ Front passenger detection sensor and passenger seat belt reminder
● If luggage is placed on the front passenger seat, the front passenger
detection sensor may cause the warning light to flash, even if a passen-
ger is not sitting in the seat.
● If a cushion is placed on the seat, the sensor may not detect a passen-
ger, and the warning light may not operate properly.
■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level.
Pushing the tire pressure warning reset switch does not turn off the tire
pressure warning light.
■The tire pressure warning light may turn on due to natural causes
The tire pressure warning light may turn on due to natural causes such
as natural air leaks or tire inflation pressure changes caused by temper-
ature. In this case, adjusting the ti re inflation pressure will turn off the
warning light (after a few minutes).
■When a tire is replaced with a spare tire
The compact spare tire is not equipped with the tire pressure warning
valve and transmitter. If a tire goes flat, the tire pressure warning light will
not turn off even though the flat tire is replaced with the spare tire.
Replace the spare tire with the repair ed tire and adjust the proper tire
inflation pressure. The ti re pressure warning light will turn off after a few
minutes.

420 5-2. Steps to take in an emergency
■If the tire pressure warning system is inoperative
The tire pressure warning system will be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If tires not equipped with 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.
●If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm2 or bar) or
higher.
The tire pressure warning system may be disabled in the following condi-
tions:
(When the condition becomes normal, the system will work properly.)
●If electronic devices or facilities using similar radio wave frequencies
are nearby.
●If a radio set at similar frequencies is in use in the vehicle.
●If a window tint that affects the radio wave signals is installed.
●If there is a lot of snow or ice on the vehicle, in particular around the
wheels or wheel housings.
●If non-genuine Toyota wheels are used. (Even if you use Toyota
wheels, the tire pressu re warning system may not work properly with
some types of tires.)
●If tire chains are used.
■If the tire pressure warning light frequently comes on after blinking
for 1 minute
If the tire pressure warning light comes on after blinking for 1 minute fre-
quently when the engine switch is turned to the “ON” position, have it
checked by your Toyota dealer.
■ Customization that can be co nfigured at Toyota dealer
The vehicle speed linked seat belt reminder buzzer can be disabled.
(Customizable features P. 485) However, Toyota recommends that the
seat belt reminder buzzer be operational to alert the driver and front passen-
ger that the seat belts are not fastened.
