7-2. Steps to take in an emergency
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.
Install the spare tire and loosely
tighten each wheel nut by hand by
approximately the same amount.
Turn the wheel nuts until the washers
come into contact with the disc wheel .
Lower the vehicle.
Firmly tighten each wheel nut two
or three times in the order shown in
the illustration.
Tightening torque:
131 N•m (13.4 kgf•m, 97 ft•lbf)
Reinstall the wheel ornament.
• Have the wheel nuts tightened with a
torque wrench to 131 N•m (13.4 kgf•m,
97 ft•lbf), 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.
O In cases such as when replacing tires,
make sure to cancel the power back
door system. (oP.161) Failure to do so
may cause the back door to operate
unintentionally if the power back door
switch is accidentally touched, result-
ing in hands and fingers being caught
and injured.
