A discharged battery can freeze at tempera-
tures below freezing point. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is a risk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
If the indicator/warning lamps do not light up
in the instrument cluster when temperatures
are low, it is probably because the discharged
battery has frozen. Should this be the case, do
not jump-start the vehicle or charge the bat-
tery. The service life of a thawed battery may
be shorter. Start-up behavior may deterio-
rate, in particular at low temperatures. Have
the thawed battery checked at a qualified
specialist workshop.
