NOTICE
■Driving with tire chains and
the compact spare tire
Do not fit tire chains to the com-
pact spare tire. Tire chains may
damage the vehicle body and
adversely affect driving perfor-
mance.
■When replacing the tires
(vehicles with a tire pressure
warning system)
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
transmitters (vehicles with a
tire pressure warning system)
When a tire is repaired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant 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.
If the engine will not
star t
If the engine will not start
even though correct starting
procedures are being fol-
lowed ( P.154, 155), con-
sider each of the following
points:
The engine will not start
even though the starter
motor operates normally.
The starter motor turns
over slowly, the interior
lights and headlights are
dim, or the horn does not
sound or sounds at a low
volume.

4008-1. Specifications
adversely affected.
The malfunction indicator lamp on
the instrument cluster may come on.
If this happens, contact your Toyota
dealer for service.
■If your engine knocks
●Consult your Toyota dealer.
●You may occasionally notice light
knocking for a short time while
accelerating or driving uphill. This
is normal and there is no need for
concern.
NOTICE
■Notice on fuel quality
●Do not use impro per 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.
●Do not use gasohol other than
the type previously stated.
Other gasohol may cause fuel
system damage or vehicle per-
formance problems.
●Using unleaded gasoline with
an octane number or rating
lower than the l evel previously
stated will cause persistent
heavy knocking.
At worst, this will lead to engine
damage.
■Fuel-related poor driveability
If poor driveability (poor hot start-
ing, vaporization, engine knock-
ing, etc.) is encountered after
using a different type of fuel, dis-
continue the use of that type of
fuel.
■When refueling with gasohol
Take care not to spill gasohol. It
can damage your vehicle’s paint.

Vehicle specifications
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. Performance may differ
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 high-
est to lowest, are AA, A, B and
C, and they represent the tire’s
ability to stop on wet pavement
as measured under controlled
conditions on specified govern-
ment 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 corner-
ing (turning) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, repre-
senting the tire’s resistance to
the generation of heat and its
ability to dissipate heat when
tested under controlled condi-
tions on a specified indoor labo-
ratory 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.
Grade C corresponds to a level of
performance which all passenger
car tires must meet under the Fed-
eral Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher
levels of performance on the labo-
ratory test wheel than the minimum
required by law.
Warning: The temperature grades
of a tire assume tha t it is properly
inflated and not overloaded.
Excessive speed, underinflation, or
excessive loading, either sepa-
rately or in combination, can cause
heat buildup and possible tire fail-
ure.

which a tire may be inflated, shown on the
