■Replacing a flat tire
●Do not touch the disc wheels or 
the area around the brakes 
immediately 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 precau-
tions could cause the wheel 
nuts to loosen and the tire to fall 
off, resulting in death or serious 
injury.
• Never use oil or grease on the  wheel bolts or wheel nuts.
Oil and grease may cause the 
wheel nuts to be excessively 
tightened, leading to bolt or disc 
wheel damage. In addition, the 
oil or grease can cause the 
wheel nuts to loosen and the 
wheel may fall off, causing an 
accident and resulting in death 
or serious injury. Remove any 
oil or grease from the wheel 
bolts or wheel nuts.
• 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-
cifically designed for that wheel.
• If there are any  cracks or defor-
mations in the bolt screws, nut 
threads or bolt holes of the 
wheel, have the vehicle 
inspected by your Toyota 
dealer.
• Do not attach a  heavily dam-
aged wheel ornament, as it may 
fly off the wheel while the vehi-
cle is moving.
●Observe the fo llowing precau-
tions.
Failure to do so may result in 
serious injury:
• Do not try to remove the wheel  ornament by hand. Take due 
care in handling the ornament to 
avoid unexpected personal 
injury.
• Lower the spare tire completely  to the ground before removing it 
from under the vehicle.
■Replacing a flat  tire for vehi-
cles with power back door
In cases such as when replacing 
tires, make sure to turn off the 
power back door main switch 
(  P.526). Failure to do so may 
cause the back door to operate 
unintentionally if the power back 
door switch is accidentally 
touched, resulti ng in hands and 
fingers being caught and injured.
