Jump starting
The wires leading to the
power socket do not have
a load-capacity rating adequate
for jump-starting the engine. Ex-
cessively high current can lead
to a cable fire or damage to the
vehicle electronics.
Do not use the on-board socket
to jump-start the engine of the
motorcycle.
Touching live parts of the
ignition system with the
engine running can cause electric
shock.
Do not touch parts of the igni-
tion system when the engine is
running.
A short-circuit can res-
ult if the crocodile clips
of the jump leads are accident-
ally brought into contact with the
motorcycle.
Use only jump leads fitted with fully insulated crocodile clips at
both ends.
Jump-starting with a donor-
battery voltage higher than
12 V can damage the vehicle
electronics.
Make sure that the battery of the
donor vehicle has a voltage rating
of 12 V.
When jump-starting the engine,
do not disconnect the battery
from the on-board electrical
system.
Remove the battery-compart-
ment cover ( 133)
Run the engine of the donor
vehicle during jump-starting.
Begin by connecting one end
of the red jump lead to the
positive terminal of the dis-
charged battery and the other
end to the positive terminal of
the donor battery.
Then connect one end of the
black jump lead to the negative terminal of the donor battery,
and the other end to the neg-
ative terminal of the discharged
battery.
Start the engine of the vehicle
with the discharged battery
in the usual way; if the en-
gine does not start, wait a few
minutes before repeating the
attempt in order to protect the
starter motor and the donor
battery.
Allow both engines to idle for a
few minutes before disconnect-
ing the jump leads.
Disconnect the jump lead from
the negative terminals first,
then disconnect the second
lead from the positive termin-
als.
Install the battery-compartment
cover ( 134)

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
Do not turn the battery upside
down
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- pens, warranty claims will not be
accepted.
If the motorcycle is to be out of
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.
Charging 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 telltale lights fail to
light up, the battery is completely
flat. Attempting to charge a com-
pletely flat battery via the on-
board socket can cause damage
to the motorcycle's electronics.
If a battery has discharged to the
extent that it is completely flat, it
has to be disconnected from the
on-board circuits and charged
with the charger connected dir-
ectly to the battery posts.
8132zMaintenance
Page 135 of 173

Only chargers suitable for
this mode of charging can
be used to recharge the battery
via the on-board socket. Unsuit-
able chargers could cause dam-
age to the motorcycle's on-board
electrics.
Use BMW chargers with the
part numbers 71 60 7 688 864
(220 V) or, as applicable,
71 60 7 688 865 (110 V). If
you are in doubt, disconnect
the battery from the on-board
systems and connect the charger
directly to the battery.
Charge via the power sock-
et, with the battery connected
to the motorcycle's on-board
electrical system. The motorcycle's on-board
electronics know when the
battery is fully charged. The
on-board socket is switched off
when this happens. Comply with the operating in-
structions of the charger.
If you are unable to charge
the battery through the on-
board socket, you may be using
a charger that is not compatible
with your motorcycle's electron-
ics. If this happens, disconnect
the battery from the on-board
systems and connect the charger
directly to the battery.
Charging battery when
disconnectedCharge the battery using a
suitable charger.
Comply with the operating in-
structions of the charger.
Once the battery is fully
charged, disconnect the
charger's terminal clips from
the battery terminals.
The battery has to be re-
charged at regular intervals
in the course of a lengthy period
of disuse. See the instructions for caring for your battery. Al-
ways fully recharge the battery
before restoring it to use
Removing battery-
compartment cover
If it is not standing firmly,
the motorcycle could topple
