ment ".
0 Note
• App lying a higher vo ltage booster battery will cause expensive
damage to sens itive e lec tron ic components, such as contro l units,
re lays, rad io, etc.
• Th ere must be no electrical contac t between the vehicles as othe r­
wise current could a lready start to flow as soon as the posit ive(+)
t erm inals are con nected.
[I] Tips
• Th e discharged ba tte ry mus t be properly co nnecte d to the
vehicle's electrical system . When jump starting or charging the
bat tery, never connec t the negat ive ground cable to the batte ry nega­
tive post because the battery manager system must be able to detect
t he battery's state of charge . Always connect the negative ground
cable to the negative ground post of the battery manage r contro l
unit. •
