Replacing a flat tire ●
Observe the following precautions.
Failure to do so may result in serious injury:
• 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. ●
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 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. 132). Failure to do so may cause the back door to operat e unintentionally if
the power back door switch is accidentally touched, resulting in hands and fingers
being caught and injured.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following
grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 0W-20 is not available, SAE
5W-20 oil may be used. However, it
must be replaced with SAE 0W-20
at the next oil change.
Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for easier starting of
the engine in cold weather.
• The 20 in 0W-20 indicates the viscos ity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a higher
value) may be better suited if the vehicle is operated at high speeds, or
under extreme load conditions.
How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use. Outside temperature
