Coolant Checking coolant levelCheck the coolant level at reg-
ular intervals. 1 Display for coolant level
Check the coolant level in
coolant indicator 1.
2 Maximum coolant level
3 Minimum coolant level
The coolant level must be
between the MIN and
MAX marks.
If the coolant level is below the
MIN mark:
Top up the coolant.
Topping up coolant
Do not open the cooling
system while the engine
is hot, otherwise you may
scald yourself on the resultant
coolant steam. c
Remove the cap from cool- ant filler neck 1.
Add coolant.
Check the coolant level.
Repeat the filling and check-
ing procedure until the cool-
ant level is between the MIN
and MAX marks.

Maintenance
Jump starting
The wires leading to the
power socket do not
have a load-capacity rating
adequate for jump-starting the
engine. Excessively high
current can lead to a cable fire
or damage to the vehicle elec-
tronics.
Do not use the on-board sock-
et to jump-start the engine. c
Do not use proprietary
start-assist sprays or
other products to start the
engine. c
Inadvertent contact be-
tween the terminal clips
of the jump leads and the vehi-
cle can lead to short circuits.
Use only jump leads fitted with
fully insulated crocodile clips
at both ends. c Jump-starting with a
voltage greater than 12 V
can damage the vehicle
electronics.
Make sure that the battery of
the donor vehicle has a
voltage rating of 12 V. c
• When jump-starting the engine, do not disconnect
the battery from the on-
board electrical system.
• Remove the cover of the bat- tery compartment (
b
118).
• Start the engine of the donor vehicle and allow it to run for
the duration of the jump-
start procedure.
• Begin by connecting one
end of the red jump lead to
the positive terminal of the
discharged battery and the
other end to the positive ter-
minal of the donor battery. • Then connect one end of the
black jump lead to the nega-
tive terminal of the donor
battery, and the other end to
the negative terminal of the
discharged battery.
• Start the engine of the vehi-
cle with the discharged bat-
tery in the usual way; if the
engine does not start, wait a
few minutes before repeat-
ing the attempt in order to
protect the starter and the
donor battery.
• Allow both engines to idle for a few minutes before discon-
necting the jump leads.
• Disconnect the jump lead from the negative terminals
first, then disconnect the
second lead from the posi-
tive terminals.
• Screw down the cover of the battery compartment.

Touching live parts of the
ignition system with the
engine running can lead to
electric shocks.
Do not touch parts of the igni-
tion system when the engine is
running. c
BatteryMaintenance instructionsYour motorcycle is supplied
with a maintenance-free
battery.
Correct upkeep, recharging
and storage will prolong the
life of the battery and are
essential if warranty claims are
to be considered.
Compliance with the points
below is important in order to
maximise battery life: – Keep the surface of the bat-
tery clean and dry.
– Do not open the battery.
– Do not top up with water.
– Be sure to read and comply with the instructions for
charging the battery on the
following pages.
– Do not turn the battery upside down.
If the battery is not dis-
connected, the on-board
electronics (clock, etc.) will
drain the battery. This can
cause the battery to run flat. If
this happens, warranty claims
will not be accepted.
If the motorcycle is to be out of
use for more than two months,
disconnect the battery or con-
nect a suitable trickle charger
to the battery. c BMW Motorrad has de-
veloped a trickle-charger
specially designed for
compatibility with the electron-
ics of your motorcycle. Using
this charger, you can keep the
battery charged during long
periods of disuse, without hav-
ing to disconnect the battery
from the motorcycle's on-
board systems.
More information is available
on request from your
authorised BMW motorcycle
dealer. c
Charging the battery
when connected If the telltale lights do not light
up and the multifunction dis-
play remains blank when you
switch on the ignition, the bat-
tery is completely flat.

Maintenance
• Disconnect the battery's negative lead 2 first.
• Then disconnect positive lead 3.
•Slacken screws 4 and pull
the retainer to the rear.
• Lift the battery up and out; work it slightly back and forth
if it is difficult to remove.
Installing battery
The types of screw used
are listed, complete with
tightening torques, on
(
b
128). c
If it is not standing firmly,
the motorcycle could
topple in the course of the
operations described below.
Make sure that the motorcycle
is steady on its stand. c
• Switch off the ignition.
• Place the battery in the bat- tery compartment, positive
terminal on the right in the
direction of travel.
• Slip the clip over the battery and hand-tighten the
screws. •Connect the positive
lead first and hand-tighten
the screw.
• Then connect the negative lead and hand-tighten the
screw.
• Install the cover of the bat-
tery compartment and hand-
tighten the screw.
• Switch on the ignition.
• Fully open the throttle once or twice.
» The engine management system records the throttle-
valve position.
Remember to reset the
clock after reconnecting
the battery. c

Care
PlasticsClean plastic parts with water
and BMW plastic care
emulsion. This includes in
particular:
– Windscreens
– Headlight lenses made of plastic
– Covering glass of the instru- ment cluster
– Black, unpainted parts
If plastic parts are
cleaned using unsuitable
cleaning agents, the surfaces
can be damaged.
Do not use cleaning agents
that contain alcohol, solvents
or abrasives to clean plastic
parts. Even fly-remover pads
or cleaning pads with hard
surfaces can produce
scratches. c Soften stubborn dirt and
dead insects by covering
the affected areas with a wet
cloth. c
WindscreenClean off dirt and insects with
a soft sponge and plenty of
water.
Fuel and chemical
solvents attack the
windscreen.
Do not use cleaning agents. cChromeEspecially in the case of road
salt, carefully clean chrome
with plenty of water and BMW
vehicle shampoo. Use chrome
polish for additional treatment.
RadiatorClean the radiator regularly to
prevent overheating of the
engine due to inadequate
cooling. For example, use a
garden hose with low water
pressure.
Cooling fins can be bent
easily.
Take care not to bend the fins
when cleaning the radiator. cPaint careWashing the motorcycle
regularly will help counteract
the long-term effects of sub-
stances that damage the
paint, especially if your motor-
cycle is ridden in areas with
high air pollution or natural
sources of dirt, e.g. tree resin
or pollen.

Care
• Coat bright metal/chrome-plated parts with an acid-
free grease (e.g. Vaseline).
• Place the motorcycle in a dry room on the centre stand
OA
or rear wheel stand.
• Raise the engine with the
front wheel stand in such a
way that both wheels are
clear of the ground.
Before laying the vehicle
up, have the engine oil
and the oil filter element
changed by a specialist work-
shop, preferably your author-
ised BMW motorcycle dealer.
Combine work for laying up/
restoring to use with a mainte-
nance service or inspection. c
Restoring to use• Remove the protective wax
coating.
• Clean the motorcycle
(b
122).
• Install a charged battery (
b
119).
• Perform the safety checks (
b
56).
• Check the brakes (
b
93).
• Check the tyre pressures (
b
51).
