7
When trouble arises
1Remove any dirt or foreign
matter from the wheel con-
tact surface.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in
motion, causing the tire to come off.
2 Install the tire and loosely
tighten each wheel nut by
hand by approximately the
same amount.
Turn the wheel nuts until the wash-
ers come into contact with the
WARNING
■Replacing a flat tire
●Observe the following precau-
tions. Failure to do so may
result in serious injury.
• Do not touch the disc wheels or the area around the brakes
immediately after the vehicle
has been driven. After the vehi-
cle has been driven the disc
wheels and the area around the
brakes will be extremely hot.
Touching these areas with
hands, feet or other body parts
while changing a tire, etc. may
result in burns.
• Remove the spare tire before jacking up the v ehicle. If the
spare tire is removed after jack-
ing up the vehicle, the tire car-
rier and the spare tire may
interfere with the jack and cause
a serious accident.
●Failure to follow these precau-
tions could cause the wheel
nuts to loosen and the tire to fall
off, resulting in death or serious
injury.
• Have the wheel nuts tightened with a torque wrench to 76 ft•lbf
(103 N•m, 10.5 kgf•m) as soon
as possible after changing
wheels.
• When installing a tire, only use wheel nuts that have been spe-
cifically designed for that wheel.
• If there are any cracks or defor- mations in the bolt screws, nut
threads or bolt holes of the
wheel, have the vehicle
inspected by your Toyota
dealer.
• When installing the wheel nuts,
be sure to install them with the
tapered end facing inward.
(  P.437)
●For vehicles with power sliding
door and/or power back door: In
cases such as wh en replacing
tires, make sure to disable the
power sliding door system
(  P.148) and/or the power
back door system ( P.163).
Failure to do so may cause the
sliding door and/or the back
door to operate unintentionally,
resulting in hands and fingers
being caught and injured.

5328-1. Specifications
■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.
