2004 BMW MOTORRAD K 1200 S engine overheat

Status indicators222
Electronic immobiliser
(EWS)
EWS symbol is
displayed.
The key being used is not
authorised for starting, or
communication between the
key and engine electronics is
disrupted.
• Remove any other vehicle
keys located near the igni-
tion key (
b 30)
.
• Use the replacement key.
• It is best to have the defec-
tive key replaced by an
authorised BMW motorcycle
dealer (
b 32).
Fuel reserve
General warning light
lights up yellow.
Fuel reserve symbol is
displayed and flashes
10 times.The fuel tank contains a fuel
reserve of a maximum of
4 litres. The Tripmaster indi-
cates the estimated residual
operating range (
b 34).
Lack of fuel could result
in the engine cutting out
unexpectedly and this could
therefore cause a dangerous
road situation.
Do not run the fuel tank dry.c
A lack of fuel could result
in misfiring and this in
turn could damage the catalyt-
ic converter.
Do not run the fuel tank dry.c
•Refuel.
Coolant temperature
General warning light
lights up red.
Coolant temperature
indicator flashes 10 times.
Coolant temperature too high.
Continuing to ride when
the engine is overheated
could result in engine damage.
It is essential that the
measures given below are
observed.c
• Check coolant level, top up if
necessary.
• If possible, ride in the part-
load range to cool down the
engine.
• In traffic jams, switch off the
engine, but keep the ignition
on so that the radiator fan
continues to operate.

Catalytic converterIf misfiring causes unburned
fuel to enter the catalytic con-
verter, there is a danger of
overheating and damage.
For this reason, observe the
following points:
– Do not ride the motorcycle
with the fuel tank empty.
– Do not run the engine with
the spark-plug cap removed.
– In the event of engine misfir-
ing, stop the engine immedi-
ately.
– Only refuel using unleaded
fuel.
– Be sure to adhere to the
prescribed maintenance
intervals.
Unburned fuel destroys
the catalytic converter.
Note the points listed for
protection of the catalytic
converter.c
Risk of fireHigh temperatures occur at
the exhaust pipe.
If highly flammable mate-
rials (e.g. hay, leaves,
grass, clothing and luggage,
etc.) make contact with the hot
exhaust pipe, they can start to
burn.
Ensure that no highly flamma-
ble materials can come into
contact with the hot exhaust
system.c
–If the engine runs for a
longer period when the
motorcycle is stationary, the
cooling is inadequate and
overheating can occur. In
extreme cases, the motorcy-
cle could catch fire.
Do not let the engine run for
unnecessary periods when the motorcycle is stationary.
After starting, move off
immediately.c
Manipulation of the engine
electronics control unit
Manipulation of the engine
electronics control unit can
cause damage to the motorcy-
cle and therefore lead to acci-
dents. Do not manipulate the en-
gine electronics control unit.c
Any manipulation of the
engine electronics
control unit can lead to
mechanical loads for which
the components of the motor-
cycle are not configured. Dam-
age caused in this way invali-
dates the warranty.
Do not manipulate the engine
electronics control unit.c

• Fill up the tank with fuel of
the approved quality.
• Close the fuel tank cap with
firm pressure.
• Remove the key and close
the protective cap.Fuel quality
Leaded fuel destroys the
catalytic converter.
Use only unleaded fuel.c
The engine is designed to run
on:– Premium grade unleaded
fuel (98 ROZ/RON, 88 MOZ/
MON)
Fill up preferably with this fuel
to comply with the nominal
values for performance and
fuel consumption.
In addition, the following fuel
quality can be used:
– Premium grade unleaded
fuel (95 ROZ/RON, 85 MOZ/
MON)
Capacity– Usable fuel capacity:
19 litres
– Of which reserve fuel:
approx. 4 litres
The volume of fuel dis-
play in the multifunction
display only works when the
ignition is switched on.c
Brake system GeneralDescending mountain
passes
If the rear brake is used
exclusively for braking
when descending steep in-
clines, there is a risk of losing
braking efficiency. Under ex-
treme conditions, the brakes
could overheat and suffer se-
vere damage.
Use the front and rear brakes
and the engine brake.c

Care
Do not use steam jet cleaners
or high-pressure cleaners.cPlasticsClean plastic parts with water
and BMW plastic care
emulsion. This includes in
particular:
– Windscreens
– Headlight lenses made of
plastic
– Covering glass of the
instrument 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. "Fly sponges" or spong-
es with hard surfaces can also
lead to scratches.cSoften resilient dirt and
insects by applying a wet
cloth.c
WindscreenRemove dirt and insects with a
soft sponge and lots 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.
When cleaning the radiator,
ensure that the fins are not
bent.c
Paint careRegular washing of the motor-
cycle counteracts the long-
term effects of materials that
damage the paint, especially if
your motorcycle is ridden in
areas with high air pollution or
natural sources of dirt, e.g.
tree resins or pollen.
However, remove particularly
aggressive materials immedi-
ately; otherwise changes in
the paint or discolouration can
occur. These include, e.g.,
spilt fuel, oil, grease, brake
