Replacing a flat tire ●
Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it from under
the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in handling
the ornament to avoid unexpected personal injury.
• 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.
• Turn off the vehicle height control.
The vehicle height may change due to th e automatic leveling function and you
may catch part of your body in the vehicle, resulting in an accident.
( P. 3 1 8 )●
Failure to follow these precautions 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 a serious accident.
Remove any oil or grease from the wheel bolts or wheel nuts.
• Have the wheel nuts tightened wi th a torque wrench to 97 ft
• lbf (131 N
• m,
13.4 kgf
• m) as soon as possible after changing wheels.
• When installing a tire, only use whee l 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.
