QBefore recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following before recharging:
O If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
O Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the battery.

may not start with the engine switch turned off. However, the engine will
operate normally from the second attempt.
O The engine switch mode is recorded by the vehicle. If the battery is recon-

before the battery was disconnected. Make sure to turn off the engine
before disconnect the battery. Take extra care when connecting the battery
if the engine switch mode prior to discharge is unknown.
If the system will not start even after multiple attempts, contact any authorized
