CAUTION
Replacing a flat tire
■
Observe the following precautions to reduce the risk of death or serious 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.
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 with a torque wrench to 76 ft•lbf (103 N•m, 10.5
●
kgf•m) as soon as possible after changing wheels.
Failure to follow these precautions could cause the wheel nuts to loosen and the
tire to fall off, resulting in death or serious injury.
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.
Failure to follow these precautions could cause the wheel nuts to loosen and the tire
to fall off, resulting in death or serious injury.
When using the compact spare tire
■
Remember that the compact spare tire provided is specifically designed for use
●
with your vehicle. Do not use your compact spare tire on another vehicle.
Do not use more than one compact spare tire simultaneously.
●
Replace the compact spare tire with a standard tire as soon as possible.
●
Avoid sudden acceleration, deceleration and braking, as well as sharp cornering.
