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.

About BMW Motorrad Integral ABS
How does ABS work?
The maximum braking force
it is possible to transfer to the
carriageway depends, among
other things, on the road
surface's coefficient of friction.
Gravel, ice and snow, and
water on the road, have
significantly poorer coeffi-
cients of friction than a dry,
clean asphalt road surface.
The poorer the road's coeffi-
cient of friction, the longer the
braking distance.
If the maximum braking force it
is possible to apply to the road
is exceeded when the rider
increases brake pressure, the
wheels will begin to lock and
directional stability is lost; a fall
threatens. Before this situation
can arise, ABS intervenes and adapts the braking pressure to
the maximum braking force
it is possible to transfer so that
the wheels continue to turn
and driving stability is main-
tained whatever the prevailing
road conditions.
What happens with bumps
in the road?
Corrugated road surfaces or
bumps in the road can cause
the tyres to temporarily lose
contact with the road surface
and hence the braking force it
is possible to apply to drop to
zero. If the brakes are applied
in this situation, the ABS must
reduce the braking pressure to
ensure driving stability when
contact with the road surface
is restored. At this moment,
BMW Motorrad Integral ABS must assume extremely low
coefficients of friction (gravel,
ice, snow) so that the wheels
turn in any conceivable situa-
tion and thus the stability of
the motorcycle is ensured.
Once the actual circum-
stances are detected, the
system will set the brake pres-
sure to the optimum value.
What do we observe during
rider safety training?
Braking in which ABS has to
intervene has, by comparison
with normal braking, a signifi-
cantly higher demand for
electricity which puts a heavy
load on the battery. The
battery is constantly being
charged in normal riding so
that it always has sufficient
capacity available. Info_I_ABS_en_xx.fm Seite 1 Dienstag, 19. Juli 2005 2:48 14
