WARNING

■

Replacing a 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. (
