2015 Lexus IS300h oil temperature

3224-6. Driving tips
IS300h_EE(OM53D56E)
●Use fluids that are appropriate to the prevailing outside temperatures. •Engine oil
• Engine/power control unit coolant
•Washer fluid
●Have a service technician inspect the condition of the 12-volt battery.
●Have the vehicle fitted with four snow tires or purchase a set of tire chains for
the rear tires.
*
Ensure that all tires are the specified size and brand, and that chains match the size
of the tires.
*: Tire chains cannot be mounted on the 18-inch tires.
Perform the following according to the driving conditions:
●Do not try to forcibly open a window or move a wiper that is frozen. Pour
warm water over the frozen area to melt the ice. Wipe away the water imme-
diately to prevent it from freezing.
●To ensure proper operation of the climate control system fan, remove any
snow that has accumulated on the air inlet vents in front of the windshield.
●Check for and remove any excess ice or snow that may have accumulated on
the exterior lights, vehicle’s roof, chassis, around the tires or on the brakes.
●Remove any snow or mud from the bottom of your shoes before getting in the
vehicle.
Accelerate the vehicle slowly, keep a safe distance between you and the vehicle
ahead, and drive at a reduced speed suitable to road conditions.
Winter driving tips
Carry out the necessary preparations and inspections before driving the vehi-
cle in winter. Always drive the vehicle in a manner appropriate to the prevail-
ing weather conditions.

IS300h_EE(OM53D56E)
CAUTION
The engine compartment contains many mechanisms and fluids that may move suddenly,
become hot, or become electrically energized. To avoid death or serious injury, observe
the following precautions.
■When working on the engine compartment
●Make sure that the “ACCESSORY” or “IGNITION ON” on the multi-information
display and the “READY” indicator are both off.
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, power control unit, radiator, exhaust manifold, etc.
right after driving 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. Fuel fumes are flamma-
ble.
●Take care because brake fluid can harm your hands or eyes and damage painted sur-
faces. 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 power switch is off.
With the power switch in ON mode, the elec tric cooling fans may automatically start to
run if the air conditioning is on and/or the coolant temperature is high. ( →P. 4 6 2 )
■Safety glasses
Wear safety glasses to prevent flying or fallin g material, fluid spray, etc. from getting in
your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt
in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when
the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

With the engine at operating temperature and turned off, check the oil level on
the dipstick.
■Checking the engine oilPark the vehicle on level ground. After warming up the engine and turning
off the hybrid system, 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.
Wipe the dipstick clean.
Reinsert the dipstick fully.

cle or engine.
Wipe the dipstick and reinsert it fully.

■Oil capacity (Drain and refill [Reference*])
*: The engine oil capacity is a reference quantity to be used when changing the engine
oil. Warm up the engine and turn off the hybrid system, wait more than 5 minutes, and
check the oil level on the dipstick.
■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom-
mends the use of approved “Toyota Ge nuine Motor Oil”. Another motor oil of
matching quality can also be used.
Oil grade:
0W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended 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. How-
ever, 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 or 5W-30 engine oil is rec-
ommended.

IS300h_EE(OM53D56E)
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 viscosit y 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 labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.
ILSAC Certification Mark
The International Lubricant Specificatio n Advisory Committee (ILSAC) Certifica-
tion Mark is displayed on the front of the container.
