When trouble arises
Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even when
the vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the 12-volt battery
may discharge, and the hybrid system may be unable to start. (The 12-volt bat-
tery recharges automatically while the hybrid system is operating.)
WA R N I N G
Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12-volt battery:
Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
Do not allow the other end of the jumper cable connected to the “+” terminal
to come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
Do not allow the + and - clamps of the jumper cables to come into contact
with each other.
Do not smoke, use matches, cigarette lighters or allow open flame near the
12-volt battery.
12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte, while
related parts contain lead and lead compounds. Observe the following precau-
tions when handling the 12-volt battery:
When working with the 12-volt battery, always wear safety glasses and take
care not to allow any battery fluids (acid) to come into contact with skin,
clothing or the vehicle body.
Do not lean over the 12-volt battery.
In the event that battery fluid comes into contact with the skin or eyes, imme-
diately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can
be received.
Always wash your hands after handling the 12-volt battery support, terminals,
and other battery-related parts.
Do not allow children near the 12-volt battery.
After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus dealer or repairer,
or another duly qualified and equipped professional as soon as possible.
If the 12-volt battery is deteriorating, continued use may cause the 12-volt bat-
tery to emit a malodorous gas, which may be detrimental to the health of pas-
sengers.

Start the hybrid system and check for the multi-information display.
If the message does not disappear:
Stop the hybrid system and contact any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
If the message is not displayed:
Have the vehicle inspected at the nearest any authorized Lexus
dealer or repairer, or another duly qualified and equipped profes-
sional.
WA R N I N G
To prevent an accident or injury 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) getting caught,
resulting in serious injury.
Do not loosen the coolant reservoir cap 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 system has cooled down sufficiently. Add-
ing 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.
