YARIS_HV_EE_OM52G10E
■ 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.
