PRIUS_OM_OM47F01U_(U)
WARNING
■When removing the 12-volt battery terminals
Always remove the negative (-) terminal first. If the positive (+) terminal con-
tacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to el ectrical shocks
and death or serious injury.
■ Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally ignit ing 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 any other than the in tended terminal.
● 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 in to contact
with each other.
● Do not smoke, use matches, cigarette lighters or allow open fla me near
the 12-volt battery.
■ 12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the following
precautions when handling the 12-volt battery:
● When working with the 12-volt battery, always wear safety glass es and
take care not to allow any battery fluids (acid) to come into contact with
skin, clothing or the vehicle body.
● Do not lean over the 12-volt battery.
● In the event that battery fluid comes into contact with the skin or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention
can be received.
● Always wash your hands after handling the 12-volt battery support, termi-
nals, and other battery-related parts.
● Do not allow children near the 12-volt battery.

8-2. Customization
■Vehicle customization
●When the Speed linked door locking function and the Shift posit ion linked
door locking function are both on, the door lock operates as follows.
• When shifting the shift position to any position other than P, all the doors
will be locked.
• If the vehicle is started with all the doors locked, the Speed linked door locking function would not operate.
• If the vehicle is started with any door unlocked, the Speed li nked door
locking function will operate.
● When the smart key system is off, Smart door unlocking cannot be custom-
ized.
● When the doors remain closed after unlocking the doors and the automatic

WARNING
■Cautions 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, ensure that the hybrid sy stem is oper-
ating while customizing features.
