■ Routine tire inflation pressure checks (vehicles with a 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.
■ Initializing the tire pressure warning system (vehicles with a tire pres-
sure 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.
■ When initialization of the tire pressure warning system has failed (vehi-
cles with a tire pressure warning system)
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not operate
properly. If repeated attempts to record tire inflation pressure settings are
unsuccessful, have the vehicle inspected by any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
● When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
● After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.

WARNING
■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.
● 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 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.
● Vehicles with a compact spare tire: Do not tow if your vehicle has a com-
pact spare tire installed.
■ When initializing the tire pressure warning system (vehicles with a 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.
NOTICE
■ Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure warning
system)
● When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact any authorized Toyota dealer or repairer,
or another duly qualified and equipped professional as the tire pressure
warning valves and transmitters may be damaged if not handled correctly.
● Make sure to install the tire valve caps. If the tire valve caps are not
installed, water could enter the tire pressure warning valves and the tire
pressure warning valves could be bound.
● When replacing tire valve caps, do not use tire valve caps other than those
specified. The cap may become stuck.
