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
After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
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.
When replacing the 12-volt battery
P. 5 1 3
NOTICE
When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-
gled in the cooling fans or belt.
To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-
volt battery from another vehicle in an emergency. It cannot be used to jump
start another vehicle.
