7-2. Steps to take in an emergency
WARNING
■When inspecting under the hood of your vehicle
Observe the following precautions. Failure to do so may result in serious
injury such as burns.
●If steam is seen coming from under the hood, do not open the hood until the steam has subsided. The engine com-
partment may be very hot.
●After the hybrid system has been turned off, check that the “READY” indicator is off.
When the hybrid system is operating, the gasoline engine may automatically start, or the cooling fan may suddenly
operate even if the gasoline engine stops. Do not touch or approach rotat-ing parts such as the fan, which may
lead to fingers or clothing (especially a tie, a scarf or a muffler) getting caught, resulting in serious injury.
●Do not loosen the coolant inlet cap or
coolant reservoir caps while the hybrid system and radiator are hot.High temperature steam or coolant
could spray out.
NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid sys- tem has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too quickly can cause damage to the hybrid system.
■To prevent damage to the cooling sys-
tem
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.

■Oil capacity (Drain and refill [Ref-
erence*])
*: The engine oil capacity is a reference
quantity to be used when changing the
engine oil. Warm up and turn off the
engine, 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
Genuine Motor Oil”. Another motor
oil of matching quality can also be
used.
Oil grade:
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 5W-30 is filled into your Lexus
vehicle at manufacturing, and the best
choice for good fuel economy and
good starting in cold weather.
If you use SAE 10W-30 or a higher vis-
cosity engine oil in extremely low tem-
peratures, the engine may become
difficult to start, so SAE 5W-30 engine
oil is recommended.
Temperature range anticipated
before next oil change.
Preferred
Oil viscosity (5W-30 is explained here
as an example):
• The 5W in 5W-30 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 30 in 5W-30 indicates the vis-
cosity characteristic of the oil when
the oil is at high temperature. An oil
with a higher viscosity (one with a

the vehicle is operated at high
speeds, or under extreme load con-
ditions.
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 Petro-
leum Institute (API).
Center portion: “SAE 5W-30” means the
SAE viscosity grade.
Lower portion: “Resource-Conserving”
means that the oil has fuel-saving and envi-
ronmental protection capabilities.
ILSAC Certification Mark
The International Lubr icant Specification
Advisory Committee (ILSAC) Certifica-
tion Mark is displayed on the front of the
container.

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. However, it
should be replaced with SAE 0W-20
at the next oil change.
If you use SAE 10W-30 or a higher vis-
cosity engine oil in extremely low tem-
peratures, the engine may become
difficult to start, so SAE 0W-20 or
5W-30 engine oil is recommended.With filter5.7 L (6.0 qt., 5.0 Imp.qt.)
