4-3. Do-it-yourself maintenance
■Before recharging
When recharging, the battery produces hydrogen gas which is flammable and
explosive. Therefore, observe the following precautions before recharging:
●If recharging with the battery installed on the vehicle, be sure to disconnect the
ground cable.
●Make sure the power switch on the charger is off when connecting and discon-
necting the charger cables to the battery.
■If the vehicle is not used for an extended period of time
Removing the specified fuse helps to supp ress parasitic current (the draw on the
battery when the vehicle is shut off).
Turn the ignition switch to the “LOCK” position.
Open the fuse box lid in the engine compartment. ( P. 2 8 7 )
Before commencing driving again, make sure to return the fuse to its original posi-
tion.
