■Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is
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.
■ When the 12-volt battery is removed or discharged
●The hybrid system may not start. ( P. 374)
● Make sure that the key is not inside the vehicle when recharging or
replacing the 12-volt battery. The key may be locked in the vehicle if the
alarm is activated. ( P. 113)
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
does not come on, contact your Toyota dealer.
Once the hybrid system has started, remove the jumper
cables in the exact reverse or der from which they were con-
nected.
Once the hybrid system starts, have the vehicle checked at your
Toyota dealer as soon as possible.STEP3

If your vehicle overheats
Correction procedures■ If the rightmost segment of th e engine coolant temperature
display are flashing
Stop the vehicle in a safe place and turn off the air condition-
ing system, 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 radiator core
(radiator) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The following may indicate that your vehicle is overheating.
●The rightmost segment of the engine coolant temperature dis-
play ( P. 178) is flashing or a lo ss of hybrid system power is
experienced. (For example, the vehicle speed does not
increase.)
● “HYBRID SYSTEM OVERHEAT” ( P. 436) is shown on the
multi-informat ion display.
● Steam comes out from under the hood.

478 5-2. Steps to take in an emergency
Start the hybrid system and check for the multi-information
display.
If the message does not disappear:Stop the hybrid system and c ontact your Toyota dealer.
If the message is not displayed: Have the vehicle inspected at the nearest Toyota dealer.
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 injuries such as burns.
● Check that on the multi-information display and the “READY” indi-
cator are off.
● On hybrid vehicles, the gasoline engine may automatically start, or the
cooling fans may suddenly operate even if the gasoline engine stops. Do
not touch or approach rotating parts such as the fans, 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 radia-
tor are hot.
Serious injuries, 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.
■ 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.
