Checking auxiliary battery electrolyte
level
E08402500013
Before checking the auxiliary battery electrolyte lev-
el, remove the auxiliary battery's upper cover.
The electrolyte level must be between the specified
limit on the outside of the auxiliary battery. Replen-
ish with distilled water as necessary.
The inside of the auxiliary battery is divided into
several compartments; remove the cap from each
compartment and fill to the upper mark. Do not top
up beyond the upper mark because spillage during
driving could cause damage.
Check the electrolyte level at least once every 4
weeks, depending on the operating conditions.
If the auxiliary battery is not used, it will discharge
by itself with time.
Check it once every four weeks and charge with
low current if necessary.
