■
If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads
wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refilling, it may indicate a serious problem.

Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●
If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
●
Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
