Be careful when accelerating, up-
shifting, downshifting or braking on
a slippery surface. Sudden accelera-
tion or engine braking, could cause
the vehicle to spin or skid.
Do not drive in excess of the speed
limit. Even if the legal speed limit
permits it, do not drive over 140
km/h (85 mph) unless your vehicle
has highspeed capability tires.
Driving over 140 km/h (85 mph) may
result in tire failure, loss of control
and possible injury. Be sure to con-
sult a tire dealer to determine
whether the tires on your vehicle
are highspeed capability tires or
not before driving at such speeds.
Do not continue normal driving
when the brakes are wet. If they are
wet, your vehicle will require a
longer stopping distance, and it
may pull to one side when the
brakes are applied. Also, the park-
ing brake will not hold the vehicle
securely.
If you need greater traction while driv-
ing on sand, mud or snow covered
roadways, use tire chains on the front
wheels.
Always check your brakes for effective-
ness immediately after driving across
sand, mud, or water.
If operating in adverse conditions
frequently, vehicle maintenance should
be increased. (See the separate
“Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement”.)
CAUTION
Observe the following tire instruc-
tions. Otherwise, an accident may oc-
cur resulting in death or serious inju-
ries.
Keep your tire pressure at the prop-
er level. (See “—Checking tire pres-
sure” on page 247 in Section 72.)
Do not use tires (including snow
tires) of different brands, sizes,
construction or tread patterns. (See
“—Checking and replacing tires” on
page 248 and “—Installing snow
tires and chains” on page 250 in
Section 72.)
Do not use tires with different tread
wear. To equalize the tire wear, ro-
tate tires at the appropriate interval.
(See “—Rotating tires” on page 249
in Section 72.)
Use the manufacturer ’s recom-
mended wheels. Do not use wheels
of different sizes and types. (See
“—Replacing wheels” on page 252
in Section 72.)
NOTICE
Do not attempt to go offroad in your
Toyota. It is not designed for offroad
use.

Treadwear—The treadwear grade is a
comparative rating based on the wear rate
of the tire when tested under controlled
conditions on a specified government test
course. For example, a tire graded 150
would wear one and a half (11/2) times
as well on the government course as a
tire graded 100. The relative performance
of tires depends upon the actual condi-
tions of their use, however, and may de-
part significantly from the norm due to
variations in driving habits, service prac-
tices and differences in road characteris-
tics 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
ability to stop on wet pavement as mea-
sured under controlled conditions on spe-
cified 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 (turning) traction.
Temperature A, B, C— The temperature
grades are A (the highest), B, and C,
representing the tire’s resistance to the
generation of heat and its ability to dissi-
pate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature
can cause the material of the tire to de-
generate and reduce tire life, and exces-
sive temperature can lead to sudden tire
failure. The grade C corresponds to a lev-
el of performance which all passenger car
tires must meet under the Federal Motor
Vehicle Safety Standard No.109. Grades B
and A represent higher levels of perfor-
mance on the laboratory test wheel than
the minimum required by law. Warning: The temperature grades for this
tire are established for a tire that is prop-
erly inflated and not overloaded. Exces-
sive speed, underinflation, or excessive
loading, either separately or in combina-
tion, can cause heat buildup and possible
tire failure.
