Maintenance and care
Tires
Check if the treadwear indicators are showing on the tires. Also check
the tires for uneven wear, such as excessive wear on one side of the
tread.
Check the spare tire condition and pressure if not rotated.New tread
Worn tread
Treadwear indicator
The location of treadwear indicators is shown by a “TWI” or “∆” mark, etc.,
molded into the sidewall of each tire.
Replace the tires if the treadwear indicators are showing on a tire.
Rotate the tires in the order
shown.
To equalize tire wear and help
extend tire life, Toyota recom-
mends that tire rotation is carried
out approximately every 10000 km
(6000 miles).
Do not fail to initialize the tire pres-
sure warning system after tire rota-
tion.
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.

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. 392)
The compact spare tire is not equipped with a tire pressure warning
valve and transmitter.
◆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 valve and transmitter ID
codes registered by any authorized Toyota dealer or repairer, or
another duly qualified and equipped professional. ( →P. 343)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When rotating front and rear tires which have different tire infla-
tion pressures
● When changing the tire size
When the tire pressure warning system is initialized, the current tire
inflation pressure is set as the benchmark pressure.

Maintenance and care
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 compact spare tire: Do not tow if your vehicle has a compact
spare tire installed.
● Vehicles with emergency tire puncture repair kit: Do not tow anything if a
tire that has been repaired using the emergency tire puncture repair kit is
installed. The load on the tire may cause unexpected damage to the tire.
■ 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.

■Electric power steering system warning light (warning buzzer)
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on
and the warning buzzer may sound.
■ If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empt y, refuel the vehicle immediately. The
malfunction indicator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped professional
as soon as possible.
■ When the tire pressure warning light comes on
Inspect the appearance of the tire to check that the tire is not punctured.
If the tire is punctured: →P. 417, 431
If the tire is not punctured:
Carry out the following procedure after the tire temperature has lowered suffi-
ciently.
● Check the tire inflation pressure and adjust to the appropriate level.
● If the warning light does not go out even after several minutes, check that
the tire inflation pressure is at the specified level and carry out initialization.
(→ P. 343)
The warning light may come on again if the above operations are conducted
without first allowing the tire temperature to lower sufficiently.
■ The tire pressure warning light may come 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 temperature. In
this case, adjusting the tire 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 a 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 has been replaced with the spare tire. Replace the
spare tire with the repaired tire and adjus t the tire inflation pressure. The tire
pressure warning light will go off after a few minutes.

WARNING
■ If both the ABS and the brake system warning lights remain on
Stop your vehicle in a safe place immediately and contact any authorized
Toyota dealer or repairer, or another duly qualified and equipped profes-
sional. The vehicle will become extremely unstable during braking, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
When steering wheel operations are heav ier than usually, grip the steering
wheel firmly and operate it using more force than usual.
■ If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
●Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● Vehicles with spare tire: If the tire pressure warning light comes on even
after tire inflation pressure adjustment, it is probable that you have a flat
tire. Check the tires. If a tire is fl at, change it with the spare tire and have
the flat tire repaired by the nearest any authorized Toyota dealer or
repairer, or another duly qualified and equipped professional.
● Vehicles with emergency tire puncture re pair kit: If the tire pressure warn-
ing light comes on even after tire inflation pressure adjustment, it is proba-
ble that you have a flat tire. Check the tires. If a tire is flat, repair the flat tire
by using emergency tire puncture repair kit.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
NOTICE
■To ensure the tire pressure warning system operates properly
Do not install tires with different specifications or makers, as the tire pres-
sure warning system may not operate properly.

When trouble arises
If you have a flat tire (vehicles with spare
tire)
●Stop the vehicle in a safe place on a hard, flat surface.
● Set the parking brake.
● Shift the shift position to P.
● Stop the hybrid system.
● Turn on the emergency flashers. ( →P. 378)
Your vehicle is equipped with a spare tire. The flat tire can be
replaced with the spare tire.
For details about tires: →P. 3 4 1
WARNING
■ If you have a flat tire
Do not continue driving with a flat tire.
Driving even a short distance with a flat tire can damage the tire and the
wheel beyond repair, which could result in an accident.
