WARNING
■After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer as soon as possible. If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery to emit a
malodorous gas, which may be detri- mental to the health of passengers.
■When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the exchanged 12- volt battery. If not properly installed, gases (hydrogen) may leak into the vehi-
cle interior, and there is the possible dan- ger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-gled in the cooling fan or engine drive
belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt bat-tery from another vehicle in an emer-
gency. It cannot be used to jump start another vehicle.
If your vehi cle overheats

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.
●Keep hands and clothing (especially a tie, a scarf or a muffler) away from the fan and belts. Failure to do so may
cause the hands or clothing to be caught, resulting in serious injury.
●While the engine and radiator are hot, do not loosen or remove the coolant
inlet cap or coolant reservoir cap. High temperature steam or coolant could spray out.
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 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.

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.
