■ Precautions when the 12-volt battery is discharged
● In some cases, it may not be possible to unlock the doors using entry func-
tion of the smart entry & start system immediately after the 12-volt battery
has been disconnected and reconnected. Use the wireless remote control
or the mechanical key to lock or unlock the doors.
● The hybrid system may not start on the first attempt after the 12-volt battery
has recharged but will start normally after the second attempt. This is not a
malfunction.
● Vehicles with a smart entry & start system: The power switch mode is mem-
orized by the vehicle. When the 12-volt battery is reconnected, the system
will return to the mode it was in before the 12-volt battery was discharged.
Before disconnecting the 12-volt battery, turn the power switch off. If the
power switch was in ACCESSORY or ON mode before the 12-volt battery
was discharged, the audio system and/or air conditioning system may oper-
ate when the 12-volt battery is reconnected.
WARNING
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-
mable 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 anything other than the intended ter-
minal.
● Do not allow the other end of the jumper cable connected to the “+” termi-
nal 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.
■ After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Toyota 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 battery to emit a malodorous gas, which may be detrimental to the
health of passengers.

If your vehicle overheats
●The high engine coolant temperature warning light (→P. 396)
comes on or flashes, or a loss of hybrid system power is experi-
enced. (For example, the vehicle speed does not increase.)
● If the hybrid system overheat warning light (→P. 400) comes on.
● Steam comes out from under the hood.
■If the high engine coolant temperature warning light comes on
or flashes
Stop the vehicle in a safe place and turn off the air conditioning
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 radia-
tor core (radiator) for any
leaks.
Radiator
Cooling fan
If a large amount of coolant
leaks, immediately contact any
authorized Toyota dealer or
repairer, or another duly quali-
fied and equipped professional.

The coolant level is satisfac-
tory if it is between the
“FULL” and “LOW” lines on
the reservoir.
Reservoir
“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 condi tioning system is turned on immedi-
ately 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 condi-
tioning 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 any authorized
Toyota dealer or repairer, or another duly qualified and equipped
professional.
If the fan is operating:
Have the vehicle inspected at the nearest authorized Toyota
dealer or repairer, or another duly qualified and equipped profes-
sional.

WARNING
■ During customization
As the hybrid system needs to be operating during customization, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed
area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■ During customization
To prevent 12-volt battery discharge, ens ure that the hybrid system is oper-
ating while customizing features.
