■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 compartment may be very hot.
●After the hybrid system has been turned off, check that the indicator on the power
switch and the “READY” indicator are 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 rotating parts such as the fan, which may lead to fingers or clothing
(especially a tie, a scarf or a muffler) ge tting caught, resulting in serious injury.
●Do not loosen the coolant inlet cap or the
coolant reservoir caps while the hybrid sys-
tem and radiator are hot.
High temperature steam or coolant could
spray out.XGS450h

NOTICE
■When adding engine/power control unit coolant
Add coolant slowly after the hybrid system 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 system
Observe the following precautions:
●Avoid contaminating the coolant with foreign matter (such as sand or dust etc.).
●Do not use any coolant additive.

Stop the hybrid system. Set the parking brake and shift the shift lever to P.
Remove the mud, snow or sand from around the rear wheels.
Place wood, stones or some other material under the rear wheels to help pro-
vide traction.
Restart the hybrid system.
Shift the shift lever to D or R and rele
ase the parking brake. Then, while exer-
cising caution, depress the accelerator pedal.
■When it is difficult to free the vehicle
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt or snow:
Press to turn off TRC. ( →P. 3 4 6 )
WA R N I N G
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surrounding
area is clear to avoid striking other vehi cles, objects or people. The vehicle may also
lunge forward or lunge back suddenly as it becomes free. Use extreme caution.
■When shifting the shift lever
Be careful not to shift the shift lever with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an acci-
dent resulting in death or serious injury.

*: 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.
