mum charging voltage of 14.8 V.&WARNING Risk of explosion due to the
ignition of hydrogen gas
If there is a short circuit or sparks are created,
there is a danger of hydrogen gas igniting
when you charge the battery.
Make sure that the POSITIVE terminal of
a connected battery does not come into
contact with vehicle parts.Never place metal objects or tools on a
battery.When connecting and disconnecting the battery, always observe the sequence of
battery terminals described.During starting assistance, always take
care to connect only battery terminals of
identical polarity.During starting assistance, observe the sequence described for connecting and
disconnecting the jumper cables.Do not connect or disconnect the bat-
tery terminals with the engine running.&WARNING Risk of explosion due to a mix-
ture of explosive gases
A mixture of explosive gases can escape from
the battery during charging and jump starting.
Fire, open Oames, smoking and creating
sparks must be avoided.Make sure that there is suPcient ventila-
tion.Do not stand over the battery.&WARNING Risk of explosion from a frozen
battery
A discharged battery may freeze at tempera-
tures slightly above or below freezing point.
During starting assistance or battery charging,
battery gas can be released.
Always allow a battery to thaw before
charging it or performing starting assis-
tance.
If the indicator/warning lamps on the instrument cluster do not light up at low temperatures, it is
very likely that the discharged battery has frozen.
In this case, you may neither jump-start the vehi-
cle nor charge the battery.
The service life of a battery that has been thawedmay be dramatically shortened. The starting char-
