WARNING
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• 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 wh ile 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 wh eel nuts that have been specifi-
cally designed for that wheel.
• If there are any cracks or deforma tions 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 end facing inward. ( P. 500)
●For vehicles with power sliding door and/or power back door: In cases
such as when replacing tires, make sure to turn off the power sliding
door main switch ( P. 124) and/or the power back door main switch
(  P. 135). Failure to do so may cause the sliding door and/or the back
door to operate unintentionally if the power sliding door switch and/or
the power back door switch is a ccidentally touched, resulting in hands
and fingers being caught and injured.

ters
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your Toyota dealer or other qualified service shop as soon
as possible. Make sure to replace the tire pressure warning valve and
transmitter when replacing the tire. ( P. 489)
■After taking out or stowing the spare tire
Make sure to secure the tire carrier by tightening the clamp bolt to pre-
vent the holding bracket from hitting the under body of the vehicle dur-
ing driving.
■Using the tire carrier
●As the tire carrier is designed for use with the compact spare tire, it
cannot be used with standard tires.
