The coolant level is satisfactory
if it is between the “FULL” and
“LOW” line on the reservoir.Reservoir cap
“FULL”
“LOW”
Add coolant if necessary.
Water can be used in an emer-
gency if coolant is unavailable.
Start the hybrid system and turn the air conditioning system on to
check that the radiator cooling fan operates and to check for coolant
leaks from the radiator or hoses.
The fan operates when the air conditioning system is turned on immediately
after a cold start. Confirm that the fan is operating by checking the fan sound
and air flow. If it is difficult to check these, turn the air conditioning system on
and off repeatedly.
(The fan may not operate in freezing temperatures.)
If the fan is not operating:
Stop the hybrid system immediately and contact your Lexus dealer.
If the fan is operating:
Have the vehicle inspected at the nearest Lexus dealer.

When trouble arises
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.

When trouble arises
CAUTION
■When attempting to free a stuck vehicle
If you choose to push the vehicle back and forth to free it, make sure the surround-
ing area is clear to avoid striking other vehicles, objects or people. The vehicle may
also lunge forward or lunge back suddenly as it becomes free. Use extreme cau-
tion.
■When shifting the shift lever
Be careful not to shift the shift leve r with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may cause an
accident resulting in death or serious injury.
NOTICE
■To avoid damaging the transm ission and other components
●Avoid spinning the front wheels and depressing the accelerator pedal more than
necessary.
●If the vehicle remains stuck even after these procedures are performed, the vehi-
cle may require towing to be freed.
