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.
