LEXUS NX300h Owners Manu-
al_USA_OM78212U 1 Remove any dirt or foreign matter
from the wheel contact surface.If foreign matter is on the wheel contact
surface, the wheel nuts may loosen while
the vehicle is in motion, causing the tire to come off.
2 Install the spare 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 .
3 Install the wheel nut wrench in jack
handle.WARNING●
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 a serious accident.
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.
• Do not attach a heavily damaged
wheel ornament, as it may fly off the
wheel while the vehicle is moving.
■
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.119). Failure to do
so may cause the back door to operate
