NOTICE
Be sure the hybrid system and all
accessories are off before perform-
ing maintenance.
 When checking the battery, remove
the ground cable from the negative
terminal (“—” mark) first and rein-
stall it last.
 Be careful not to cause a short cir-
cuit with tools.
 Take care no solution gets into the
battery when washing it.
During recharging, the battery is pro-
ducing hydrogen gas.
Therefore, before recharging:
1. If recharging with the battery installed on the vehicle, be sure to disconnect
the ground cable.
2. Make sure the power switch on the recharger is off when connecting the
charger cables to the battery and when
disconnecting them.
CAUTION
Always charge the battery in an un-
confined area. Do not charge the
battery in a garage or closed room
where there is not sufficient ventila-
tion.
Only do a slow charge (3.5A or
less). Charging at a quicker rate is
dangerous. The battery may ex-
plode, causing personal injuries.
NOTICE
Never recharge the battery with the
hybrid system on. Also, be sure all
accessories are turned off.
