WARNING
■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 precautions
could cause the wheel nuts to loosen
and the tire to fall of f, 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, lead-
ing 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 specifically
designed for that wheel.
• 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 Lexus dealer.
●Observe the following precautions.
(RX450hL)
Failure to do so may result in serious
injury:
• Do not try to remove the wheel orna- ment by hand. Take due care in han-
dling the orname nt 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 vehicles with
power back door
In cases such as when replacing tires,
make sure to turn off the power back
door main switch ( P.472). Failure to do
so may cause the back door to operate
