Battery
Battery acid is extremely corro-
sive. Wear eye protection and
protective gloves. Do not tip the
battery. Battery acid can leak from the
ventilation openings.
Be sure that children keep well
away from batteries and battery
acid.
Wear eye protection. Do not
allow particles containing
battery acid or lead to come into
contact with your eyes, your skin, or
your clothing.
If you happen to get acid in your
eyes, rinse thoroughly for
15 minutes with clear water.
Following that, consult a physician
immediately. If your skin or clothing are
splashed with acid, rinse immediately
with plenty of soap and water. If acid is
accidentally swallowed, consult a
physician immediately.
Removal and installation
Do not disconnect the battery
when the engine is running.
Disconnecting the battery cable when
the engine is running will cause a
voltage surge which will damage the
vehicle's onboard electronics. Do not
make any modifications in the wires to
the positive terminal. If you do so, the
protective function of the safety battery
terminal is no longer ensured. Repairs
and disposal may only be performed by
specially-trained personnel.
<
When removing the battery, disconnect
the cable on the negative terminal first,
then the cable on the positive terminal.
Loosen the center adjusting screw on
the battery retaining strap (use the
screwdriver included with the onboard
tool kit) and disconnect the strap.
When installing a battery, connect the
positive terminal first, then connect the
negative terminal.
When installing a battery, be sure
that it is mounted properly and
that the retaining bracket is installed
with the center adjustment screw. If this
is not done, the battery will not be
adequately secured in case of an acci-
dent.
<
Charging the battery
Charge the battery in the vehicle only
when the engine is not running.
Before performing any work on
the electrical system, disconnect
the cable from the negative terminal. If
you do not, short circuits can create the
risk of fire or personal injury.
<
If you plan to park the vehicle for longer
than 4 weeks, disconnect the battery
from the vehicle electrical system by
disconnecting the cable at the negative
terminal. Then recharge the battery with
an appropriate battery charger.
If you intend to store the vehicle for
longer than 12 weeks, remove the
battery, charge it and store it in a cool
and dust-free room where there is no
danger of freezing. During storage,
have the battery recharged every 3
months. Also, recharge the battery
before it is reinstalled. If this is not
done, the battery will not be service-
able. Every time the battery is drained,
especially over extended periods, its
service life is reduced.
