Avoiding a discharged 12-volt battery
●Turn off the headlights and the audio system while the hybrid system is
turned off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ When the 12-volt battery is removed or discharged
The hybrid system may not start. ( P. 351)
■ Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
Start the engine of the seco nd vehicle. Increase the gaso-
line engine speed slightly and maintain at that level for
approximately 5 minutes to recharge the 12-volt battery of
your vehicle.
Open and close any of the doors with the “POWER” switch
OFF.
Maintain the engine speed of the second vehicle and turn
the “POWER” switch to ON mode, then start the hybrid sys-
tem.
Make sure the “READY” indicator comes on. If the indicator

CAUTION
■
To prevent an accident or injury when inspecting under the hood of
your vehicle
●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, caus-
ing serious injury such as burns.
● With a hybrid vehicle, there are times when the gasoline engine automati-
cally starts to run or the cooling fans suddenly start to operate. Do not
touch or approach the rotating parts of the belt or fans. Doing so may lead
to fingers, clothes or tools getting caught, resulting in an accidental injury.
● Do not loosen the coolant reservoir cap while the hybrid system and radia-
tor are hot.
Serious injury, such as burns, may result from hot coolant and steam
released under pressure.
NOTICE
■When adding engine/power control unit coolant
Wait until the hybrid system has cooled down before adding engine/power
control unit coolant.
When adding coolant, do so slowly. Adding cool coolant to a hot hybrid sys-
tem too quickly can cause damage to the hybrid system.
