How to initialize the tire pressure warning system
Park the vehicle in a safe place and turn the “ENGINE START
STOP” switch (vehicles with a smart entry & start system) or
the engine switch (vehicles without a smart entry & start sys-
tem) off.
Initialization cannot be performed while the vehicle is moving.
Adjust the tire inflation pressure to the specified cold tire infla-
tion pressure level. ( →P. 483)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the “ENGINE START STOP” switch to IGNITION ON
mode (vehicles with a smart entry & start system) or engine
switch to the “ON” position (vehicles without a smart entry &
start system).
Press and hold the tire pressure
warning reset switch until the tire

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 or 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
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 comes on after blinking
for 1 minute to indicate a system malfunction.
■ Tire life
Any tires 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.
■ Routine tire inflation pressure checks
The tire pressure warning system does no t replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.
■ If the tread on snow tires wears down 4 mm (0.16 in.)
The effectiveness of snow tires is lost.
■ Low profile tires (vehicles with 17-inch tires)
Generally, low profile tires will wear more rapidly and tire grip performance
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.
■ If you press the tire pressure wa rning reset switch accidentally
If initialization is performed, adjust the ti re inflation pressure to the specified
level and initialize the tire pressure warning system again.

WARNING
■
Tire pressure warning system operation
The tire pressure warning system may not provide warning immediately if a
tire bursts or if sudden air leakage occurs.
■ 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 handling characteristics, which may lead to an accident resulting
in death or serious injury.
●Make sure to install 4 tires that are of the specified size, and that all 4 tires
are the same size, same maker, same brand and tread pattern.
● Do not use tire sizes other than those recommended by Toyota.
● Only use radial tires.
● Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■ When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pressure
warning light may not come on even if the tire inflation pressure is low, or it
may come on when the tire inflation pressure is actually normal.
