Information on changing bulbs
Your motorcycle is equipped
with Digital Motor Electronic
(MOTRONIC) engine manage-
ment and a high-output ignition
system.
d Warning:
Only carry out work on the
electrical system when the
circuit has been interrupted
(switch off ignition). For
greater safety, disconnect
and insulate the negative bat-
tery lead.
When the engine is running or
the ignition is switched on, do
not touch any electrically live
components, terminals or
wiring.
–Risk of fatal accident!
e Important:
Your vehicle has a high-beam/
low-beam bulb, a brake-light
bulb/rear-light bulb, a parking-
light bulb, a bulb for the
number-plate light, and four
bulbs for the turn indicators.
If any of these bulbs fail, you
may have problems in seeing
and being seen.
You should therefore always
carry spare bulbs on the motor-
cycle.
L Note:
Do not touch the glass of new
bulbs with the fingers.
Use a clean, dry cloth to hold
the bulbs when inserting them.
Dirt deposits, in particular oil
and grease, interfere with heat
radiation from the bulb. This
leads to overheating and short-
ens the bulb’s operating life.

Battery safety instructions
Gel batteries are maintenance-
free. Compliance with the
instructions below is important
in order to maximise battery life:
e Attention:
– Keep the surface of the battery clean and dry
– Do not attempt to open the battery
– Do not attempt to top up the battery with water
– Use only electronically
controlled battery chargers
with a limit voltage of 14.4 V to
charge the battery.
Correct upkeep, recharging
and storage will prolong the life
of the battery and are essential
if warranty claims are to be con-
sidered.
d Warning:
Do not attempt to jump-start
the motorcycle using the on-
board socket
–Risk of fire!
 Push-start the motorcycle only when the engine is
cold.
The load capacity of the
electrical wiring to the power
socket is not sufficient to start
the motorcycle from an outside
source.
e Attention:
Do not attempt to jump-start
the motorcycle if the battery is
completely flat: recharge the
battery instead.
Risk of damaging the control
units.
