WARNING
■
Replacing a flat tire
●
Do not touch the disc wheels or the area around the brakes immedi-
ately 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 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 wheel, have the vehicle inspected by
your Toyota dealer.
• When installing the wheel nuts, be sure to install the wheel nuts with
the tapered ends facing inward.

7-2. Steps to take in an emergency
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
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.
Install the spare tire and loosely tighten each wheel nut by hand by
approximately the same amount.
When replacing an aluminum
wheel with a steel wheel
(including a compact spare
tire), tighten the wheel nuts until
the tapered portion comes into
loose contact with the disc
wheel seat.
When replacing an aluminum
wheel with an aluminum wheel,
turn the wheel nuts until the
washers come into contact with
the disc wheel.
