Battery dangers
Always read the follow-
ing instructions carefully
when handling a battery.
Keep lighted cigarettes
and all other flames or
sparks away from the
battery.
Hydrogen, a highly com-
bustible gas, is always
present in battery cells
and may explode if ignit-
ed.
Keep batteries out of the
reach of children because
batteries contain highly
corrosive SULFURIC
ACID. Do not allow bat-
tery acid to contact your
skin, eyes, clothing or
paint finish.

WARNING (Continued)
If any electrolyte gets
into your eyes, flush
your eyes with clean
water for at least 15 min-
utes and get immediate
medical attention. If elec-
trolyte gets on your skin,
thoroughly wash the
contacted area. If you
feel a pain or a burning
sensation, get medical
attention immediately.
Wear eye protection
when charging or work-
ing near a battery.
Always provide ventila-
tion when working in an
enclosed space.

Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlamps or interior
lamps were left on whilst the vehi-
cle was not in use), recharge it by
slow trickle (charging) for 10 hours.
• If the battery gradually discharges
because of high electric load whilst
the vehicle is being used, recharge
it at 20-30A for 2 hours.When recharging the battery,
observe the following precau-
tions:
•The battery must be removed
from the vehicle and placed in
an area with good ventilation.
•Do not allow cigarettes, sparks,
or flames near the battery.
•Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
•Wear eye protection when
checking the battery during
charging.
