CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may resu
lt in serious injury:
• Do not touch the disc wheels or the area around the brakes imme- diately after the vehicle has been driven.
After the vehicle 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 vehicle. If the spare tire is removed after jacking up the vehicle, the tire carrier and the
spare tire may interfere with the jack and cause a serious accident.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the tire to fall off, resulting on 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 specifi- cally designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads or bolt holes of the wh eel, 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. 705)
