Charge battery when
connected
Charging the connected
battery directly at the bat-
tery terminals can damage the
vehicle electronics.
Always disconnect the battery
from the on-board circuits be-
fore recharging it with a charger
connected directly to the battery
posts.
If you switch on the igni-
tion and the multifunction
display and indicator lights fail
to light up, the battery is com-

If a battery has discharged to the
extent that it is completely flat, it

Only chargers suitable for
this mode of charging can
be used to recharge the battery

suitable charger is available from
your authorised BMW Motorrad
dealer.

the battery from the on-board
systems and connect the charger
directly to the battery.
