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 imm edi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area
around the brakes will be extreme ly hot. Touching these areas with
hands, feet or other body parts while changing a tire, etc. may result
in burns.
• Remove the spare tire before jacking up the vehicle. If the sp are tire
is removed after jacking up the vehicle, the tire carrier and t he 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 t ire 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 spe cifi-
cally designed for that wheel.
• If there are any cracks or defo rmations 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, b e sure to install them with the
tapered end facing inward. ( P. 433)
●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 s liding
door main switch ( P. 124) and/or the power back door main switch
(  P. 136). Failure to do so may cause the sliding door and/or the back
door to operate unintentionally if the power sliding door switc h and/or
the power back door switch is accidentally touched, resulting i n hands
and fingers being caught and injured.

ter from the wheel contact sur-
face.

off.
Install the tire and loosely
tighten each wheel nut by hand
by approximately the same
amount.
Tighten the wheel nuts until the
tapered portion comes into loose
contact with the disc wheel seat.
Lower the vehicle.
Firmly tighten each wheel nut
two or three times in the order
shown in the illustration.
