Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over abattery.
GWARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any battery gases. Do not lean over
the battery. Keep children away from batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
GWARNING
Ad ischarged battery can freeze at tempera-
tures below freezin gpoint. When jump-start-
ing the vehicle or charging the battery, gases can escape from the battery. There is arisk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with amaximum
charging voltage of 14.8 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment. If the indicator/warning lamps do not light up at
low temperatures, it is very likely that the dis-
charged battery has frozen. In this case, you
may neither charge the battery nor jump-start
the vehicle. The service life of
athawed-out bat-
tery may be shorter .The starting characteristics
can be impaired, particularly at low tempera-
tures. Have the thawed-out battery checked at a
qualified specialist workshop.
Read the battery charger's operating instruc-
tions before charging the battery.
XOpen the hood.
XConnectt he battery charger to the positive
terminal and ground point in the same order
as when connectin gthe donor battery in the
jump-starting procedure (
