NOTICE
■When adding engine coolant
Add coolant slowly after the engine has cooled down sufficiently. Adding cool
coolant to a hot engine too quickly can cause damage to the engine.
■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 commercially available coolant additives.

7-2. Steps to take in an emergency
If your vehicle overheats (hybrid vehicles)
■If the needle of the engine coolant temperature gauge enters the red
zone
Stop the vehicle in a safe place an d turn off the air conditioning sys-
tem, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the hybrid system has
cooled down sufficiently,
inspect the hoses and cooling
system for leaks.
If a large amount of coolant leaks,
immediately contact your Lexus
dealer.
The following may indicate that your vehicle is overheating.
●The needle of the engine coolant temperature gauge ( P. 9 3 )
enters the red zone or a loss of hybrid system power is experienced.
(For example, the vehicle speed does not increase.)
●“Hybrid System Overheat” ( P. 772) is shown on the multi-informa-
tion display.
●Steam comes out from under the hood.

CAUTION
■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.
●Check that the indicator on the “POWER ” switch and the “READY” indicator are
off.
●On hybrid vehicles, 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) getting caught, resulting in serious injury.
●Do not loosen the radiator cap while th e 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 syst em has cooled down sufficiently. Adding
cool coolant to a hot hybrid system too quickly can cause da mage 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 commercially available coolant additives.

If the vehicle becomes stuck
Stop the engine . Set the parking brake and shift the
shift lever to P.
Remove the mud, snow or sand from around the front wheels.
Place wood, stones or some other material under the front wheels to
help provide traction.
Restart the engine .
Shift the shift lever to D or R and release the parking brake. Then, while
exercising 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:

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Use Lexus
approved “Toyota Genuine Motor Oil” or equivalent to satisfy the fol-
lowing 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
starting 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 expl ained here as an example):
• The 0W in 0W-20 indicates the ch aracteristic 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 visc osity 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 su ited if the vehicle is operated at
high speeds, or under extreme load conditions.
How to read oil container label:
The ILSAC (International Lubri-
cant Standardization and
Approval Committee) Certifica-
tion Mark is added to some oil
containers to help you select the
oil you should use.
