633 5-2. Steps to take in an emergency
When trouble arises
YARIS_F (including HV)_WE_52C79E
The hybrid system may not start on the first attempt after the 12-volt bat-
tery has recharged but will start normally after the second attempt. This is
not a malfunction.
Vehicles with an electronic key: The “POWER” switch mode is memo-
rized 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 dis-
charged. 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 operate when the 12-volt battery is reconnected.
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 certain 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 battery recharges automatically while the hybrid system is oper-
ating.)
CAUTION
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.
