5-2. Steps to take in an emergency
CAUTION
 Replacing a flat tire
 Do not touch the disc wheels or the area around the brakes immediately
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.
 Failure to follow these precautions 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 103 N•m
(10.5 kgf•m, 76 ft•lbf) as soon as possible after changing wheels.
• When installing a tire, only use wheel nuts that have been specifically
designed for that wheel.
• If there are any cracks or deformations in the bolt screws, nut threads
or bolt holes of the wheel, have the vehicle inspected by any autho-
rized Toyota dealer or repairer, or another duly qualified and equipped
professional.
• When installing the wheel nuts, be sure to install the wheel nuts with
the tapered ends facing inward. (P. 448)
 After using the tools and jack
Before driving, make sure all the tools and jack are securely in place in their
storage location to reduce the possibility of personal injury during a collision
or sudden braking.
