NOTICE
■Replacing tire pressure warning valves and transmitters
●Because tire repair or replacement may affect the tire pressure warn-
ing valves and transmitters, make sure to have tires serviced by your
Toyota dealer or other qualified service shop. In addition, make sure to
purchase your tire pressure warning valves and transmitters at your
Toyota dealer.
●Ensure that only genuine Toyota wheels are used on your vehicle.
Tire pressure warning valves and transmitters may not work properly
with non-genuine wheels.

If your vehicle needs to be towed
Before towingThe following may indicate a problem with your transmission. Contact
your Toyota dealer before towing.
● The hybrid system is operating, but the vehicle will not move.
● The vehicle makes an abnormal sound.
If towing is necessary, we recommend having your vehicle towed by
your Toyota dealer or a commerci al towing service, using a lift-type
truck or a flat bed truck.
Use a safety chain system for all to wing, and abide by all state/pro-

5-2. Steps to take in an emergency
NOTICE
■Do not drive the vehicle with 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.
■When replacing the tires
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your
Toyota dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmit-
ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 479)
■When stowing the flat tire
●Ensure that there is no object caught between the tire and the vehicle
underbody.
●Tighten the spare tire clamp bolt to hold the spare wheel carrier by the
hook securely.

■Toyota does not recommen d gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
Toyota does not recommend the use of gasoline that contains MMT. If fuel
containing MMT is used, your emission control system may be adversely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your Toyota dealer for service.
NOTICE
■ Notice on fuel quality
●Do not use improper fuels. If improper fuels are used the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its
effectiveness and the emission control system to function improperly.
● Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
■ Fuel-related poor driveability
If after using a different type of fuel, poor driveability is encountered (poor
hot starting, vaporization, engine knocking, etc.), discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle's paint.

592 6-1. Specifications
■Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represen t the tire's ability to stop on wet pavement as
measured under controlled cond itions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire's resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
The grade C corresponds to a level of performance which all passen-
ger car tires must meet under the Federal Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
