To check battery electrolyte level, open the
auxiliary battery cover.
1. Open the luggage floor board.
Refer to “Luggage floor box” on page
7-15.
2. Insert your hand in the gap (A), and open
the auxiliary battery cover (B).
3. When closing the auxiliary battery cover
(B), press down on the locations of the 4
tabs (C) from the top surface of the cover
to close it securely.
The electrolyte level must be between the
specified limit on the outside of the auxiliary
battery. Replenish with distilled water as nec-
essary.
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
four weeks, depending on the operating con-
ditions.
If the auxiliary battery is not used, it will dis-
charge by itself with time.
The capacity of the auxiliary battery is
reduced at low temperatures. This is an inevi-
table result of its chemical and physical prop-
erties. This is why a very cold auxiliary
battery, particularly one that is not fully
charged will only deliver a fraction of the
starter current which is normally available.
We recommend you to have the auxiliary bat-
tery checked before the start of cold weather
and, if necessary, have it charged or replaced.
This does not only ensures reliable starting,
but a auxiliary battery which is kept fully
charged also has a longer life.
To disconnect the battery cable, put the oper-
ation mode of the power switch in OFF to
stop the Hybrid EV System, first disconnect
