indicators in the display tell you
that a bulb defect has occurred.A defective bulb places
your safety at risk because
it is easier for other users to
oversee the motorcycle.
Replace defective bulbs as
soon as possible; always carry a
complete set of spare bulbs if
possible.
The bulb is pressurised and
can cause injury if dam-
aged.
Wear protective goggles and
gloves when changing bulbs.
The types of bulb fitted to
your motorcycle are listed
in the section entitled "Technical
data".
Do not touch the glass of
new bulbs with your fingers.
Use a clean, dry cloth to hold
the bulbs when handling them.
Dirt deposits, in particular oil and
grease, interfere with heat radi- ation from the bulb. This leads
to overheating and shortens the
bulb's operating life.

Install the battery-compartment
cover ( 128)BatteryMaintenance instructionsCorrect upkeep, recharging and
storage will prolong the life of
the battery and are essential if
warranty claims are to be con-
sidered.
Compliance with the points be-
low is important in order to max-
imise battery life:Keep the surface of the battery
clean and dry
Do not open the battery
Do not top up with water Be sure to read and comply
with the instructions for char-
ging the battery on the follow-
ing pages

If the battery is not discon-
nected, the on-board elec-
tronics (e.g. clock, etc.) gradually
drain the battery. This can cause
the battery to run flat. If this hap-

use for more than four weeks,
disconnect the battery or con-
nect a suitable trickle charger to
the battery.
BMW Motorrad has de-
veloped a float charger spe-
cially designed for compatibility
with the electronics of your mo-
torcycle. Using this charger, you
can keep the battery charged
during long periods of disuse, without having to disconnect the
battery from the motorcycle's
on-board systems. You can ob-
tain additional information from
your authorised BMW Motorrad
dealer.
