5-2. Steps to take in an emergency
CT200h_OM_OM76067E_(EE)
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. 5 1 1 )
If the 12-volt battery discharges while the shift position is in P, it may not
be possible to shift the shift position to other positions. In this case, the
vehicle cannot be towed without lifting both front wheels because the
front wheels will be locked. (P. 563)
When the 12-volt battery is reconnected, start the hybrid system and
confirm that the shift position can be changed to each position using the
shift position indicator.
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. 142)
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 operating.)

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 any other than the intended termi-
nal.
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.
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 glasses 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 battery support, terminals, and
other battery-related parts.
Do not allow children near the 12-volt battery.
