CAUTION
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from under the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling the ornament to avoid unexpected personal 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 extremel y 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 as soon as possible after changing wheels.

• When installing a tire, only use wheel nuts that have been specifi- cally designed for that wheel.
• Retighten the wheel nuts within 100 miles (160 km) of driving.
• 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 them with the
tapered ends facing inward. ( P. 572)
●Do not attach a heavily damaged wheel ornament, as it may fly off the
wheel while the ve hicle is moving.
