Maintenance and care
RX350/270_EE
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precaution:
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fans and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine
compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted
surfaces.
If fluid gets on your hands or in your eyes, flush the affected area with clean water
immediately.
If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the “ENGINE START STOP” switch is off.
With the “ENGINE START STOP” switch in IGNITION ON mode, the electric
cooling fans may automatically start to run if the air conditioning is on and/or the
coolant temperature is high. (→P. 4 7 8 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting
in your eyes

Engine oil
With the engine at operating temperature and turned off, check the oil
level on the dipstick.
■Checking the engine oil
Park the vehicle on level ground. After warming up the engine
and turning it off, wait more than 5 minutes for the oil to drain
back into the bottom of the engine.

Holding a rag under the end, pull
the dipstick out.

Vehicle specifications
RX350/270_EERecommended viscosity (SAE):
SAE 0W-20 is filled into your
Lexus vehicle at manufacturing,
and the best choice for good fuel
economy and good starting in cold
weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used.
However, it should be replaced
with SAE 0W-20 at the next oil
change.
If you use SAE 10W-30 or a
higher viscosity engine oil in
extremely low temperatures, the
engine may become difficult to
start, so SAE 0W-20, 5W-20 or
5W-30 engine oil is recom-
mended.
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 viscosity 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.
