Before recharging

When recharging, the 12-volt battery produces hydrogen gas which is flam-
mable  and  explosive.  Therefore,  observe  the  following  precautions  before
recharging:

●

If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.

●

Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.

■

After recharging/reconnecting the 12-volt battery

●

Unlocking the doors using the smart key system may not be possible imme-
diately after reconnecting the 12-volt battery. If this happens, use the wire-
less remote control or the mechanical key to lock/unlock the doors.

●

Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. However, the
hybrid system will operate normally from the second attempt.

●

The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to the status it
was in before the 12-volt battery was disconnected. Make sure to turn off
the  power  before  disconnecting  the  12-volt  battery. Take  extra  care  when
connecting the 12-volt battery if the power switch mode prior to discharge is
unknown.

If the system will not start even after multiple attempts, contact your Toyota
dealer.
