7-2. Steps to take in an emergency
When the 12-volt battery is removed or discharged
■
In some cases, it may not be possible to unlock the doors using the smart
●
entry & start system when the 12-volt battery is discharged. Use the wire-
less 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.
The power switch mode is memorized by the vehicle. When the 12-volt bat-
●
tery 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 you are unsure what mode the power switch was
in before the 12-volt battery discharged, be especially careful when recon-
necting the 12-volt battery.
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. 349)
When the 12-volt battery is reconnected, start the hybrid system and con-
●
firm that the shift position can be changed to each position using the shift
position indicator.
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.)
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 any other than the intended 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 into contact
●
with each other.
Do not smoke, use matches, cigarette lighters or allow open flame near
●
the 12-volt battery.
