Maintenance and care
Remove any dirt or foreign mat-
ter from the wheel contact sur-
face.
If foreign matter is on the wheel
contact surface, the wheel nuts
may loosen while the vehicle is in

off.
WARNING
■Replacing a tire
●Observe the following precautions.
Failure to do so may result in serious injury:
Do not touch the disc wheels o r the area around the brakes imme di-
ately after the vehi cle 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 han ds,
feet or other body parts while c hanging a tire, etc., may result in burns.
●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.
• Never use oil or grease on t he wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight -
ened, leading to bolt or disc wheel damage. In addition, the oi l or
grease can cause the wheel nuts to loosen and the wheel may fal l
off, causing a serious accident.
Remove any oil or grease from t he wheel bolts or wheel nuts.
• Have the wheel nuts tightened with a torque wrench to 76 ft·lb f
(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, be sure to install the wheel n uts with
the tapered ends facing inward. ( P. 3 5 0 )
