Warning messages
The warning message illustrations used are intended as examples, and may differ from
the image that is actually displaye d on the multi-information display.■
Warning message in radar cruise mode
In the following cases, the wa rning message may not be displa yed even if vehicle-to-vehi-
cle distance decreases: ●
When your vehicle and the vehicle ahead ar e traveling at the same speed or the vehi-
cle ahead is traveling more quickly than your vehicle●
When the vehicle ahead is traveling at a very low speed ●
Immediately after cruise control speed is set ●
At the instant the accelerator pedal is depressed ■
The LDA (Lane Departure Alert with steering control) lane departure warning func-
tion
In the following situations, th e warning message will not be displayed even if a lane line is
crossed. ●
When the vehicle speed deviates from the operating range of the LDA system func-
tions (  P. 266)●
When the lane lines cannot be recognized (  P. 267)■
Resetting the message indicating ma intenance is required (if equipped)
Make sure to reset the oil change system. (  P. 385, 403)■

RC350_RC300 AWD_RC3 00_RC F_U(OM24748U)Raise the vehicle until the tire is
slightly raised off the ground.
Remove all the wheel nuts and the
tire. When resting the tire on the ground,
place the tire so that the wheel design
faces up to avoid scratching the wheel
surface. 4

WARNING ■
Replacing a flat tire ●
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 cau se 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.
• Do not attach a heavily damaged wheel or nament, as it may fly off the wheel while
the vehicle is moving.
• 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.

Engine oil selection (RC350/RC300 AWD)
“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 be fore 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 ve hicle is operated at high speeds, or
under extreme lo ad conditions.

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

If SAE 5W-30 is not available, SAE
10W-30 oil may be used. However,
it should be replaced with SAE 5W-

Oil viscosity (5W-30 is explained here as an example):
• The 5W in 5W-30 indicates the charact eristic of the oil which allows cold
