7-2. Steps to take in an emergency

When recharging or replacing the 12-volt battery

■
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. 84)
In some cases, it may not be possible to unlock the doors using the smart access
●
system with push-button start 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 battery 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 dis-
charged, be especially careful when reconnecting the 12-volt battery.
CAUTION

Avoiding 12-volt battery fires or explosions

■
Observe the following precautions to prevent accidentally igniting the flammable
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 "+" terminal 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.
