Charging the battery
G WARNING
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 ab attery.

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.
G WARNING
Ad ischarged battery can freeze at tempera-
tures below freezin gp oint. When jump-start-
ing the vehicle or charging the battery, gases
can escape from the battery. There is ar isk of
an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.

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

charged battery has frozen. In this case, you
may neither charge the battery nor jump-start
the vehicle. The service life of at hawed-out bat-
tery may be shorter .T he starting characteristics
can be impaired, particularly at low tempera-
tures. Have the thawed-out battery checked at a
