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.)
