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 cor-
rectly.
●Replace the grommets for the tire pressure warning valves and trans-
mitters as well.
■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. 560)

688 6-1. Specifications
■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.
■ Toyota does not recommend blende d gasoline (Flex-fuel engine)
Do not use non-specified fuels such as the following.
• Fuels containing methanol.
• Fuels with more than 85% ethanol.
■ Toyota does not recommend the use of after-market fuel additives
(Flex-fuel engine)
Do not use any after-market fuel additives when repeatedly refueling with
E85, as some after-market fuel additives are not compatible with E85.
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 can cause damage to your vehicle’s three-way catalytic
converters causing the emission control system to malfunction.
● Gasoline engine: Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Use of unleaded gasoline with an octane rating lower than 87 may result in
engine knocking. Persistent knocking can lead to engine damage and
should be corrected by refueling with higher octane unleaded gasoline.

694 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 represent the tire’s ab ility 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.
