▼ Inspecting Electrolyte Level
A low level of electrolyte fluid will cause
the battery to discharge quickly.
Upper level
Lower level
Inspect the electrolyte level at least once a
week. If it is low, remove the caps and add
enough distilled water to bring the level
between the upper and lower level
(illustration).
Do not overfill.
Examine the specific gravity of the
electrolyte with a hydrometer, especially
during cold weather. If it is low, recharge
the battery.
▼ Battery Recharging
NOTE
Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
To disconnect the battery, remove the
negative lead first. Install it last when
connecting the battery.
Be sure to remove the caps before
recharging the battery.
(With i-stop system)
Do not quick-charge the battery.

Maintenance and Care
Owner Maintenance
If the battery quickly discharges
because, for example, the lights were
left on too long with the engine off,
slow-charge it as required by battery
size and charger capacity.
If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it as
required by battery size and charger
capacity.
