How Hill Start Control works
Hill Start Control is a pullaway
assistant that operates on the
partially integral ABS system to
prevent the vehicle from rolling
back on a gradient, without
the rider having to keep pres-
sure applied to the brake lever.
When Hill Start Control is ac-
tivated, pressure is built up in
the rear brake system to keep
the machine at a standstill on a
gradient.
Behaviour when the
motorcycle rolls or slips
If the vehicle starts to roll
while Hill Start Control is
active, brake pressure is
increased.
If the rear wheel slips, the
brake is released again after
approx. 1 m. This prevents
the vehicle slipping with a
locked rear wheel, for ex-
ample.
Brake release when engine is
stopped or after time-out
Hill Start Control is deactivated
if the rider stops the engine
by hitting the emergency-off
switch (kill switch) or when the
side stand is extended, or after
time-out (10 minutes).
In addition to the indicator and
warning lights, the rider should
be made aware that Hill Start
Control has been deactivated
by the following behaviour:
Brake warning jolt
The brake is released briefly
and reactivated immediately.
This creates a jolt which the
rider feels.
The partial integral ABS
brake system limits the speed
of movement to approx.
1...2 km/h.
The rider must brake the mo-
torcycle manually.
After two minutes, or when
the brake is actuated, speed
control is completely deactiv-
ated.
The holding pressure
is released immediately
without a brake warning jolt as
soon as the ignition is switched
off.

ADAPTIVE HEADLIGHT

Function
In addition to the bulbs for low
beam, high beam and, if ap-
plicable, daytime riding light
or side light, the headlight has
separate LED segments for the
cornering light. The LED seg-
ments are activated as a func-
tion of bank angle in addition
to the low-beam headlight, en-
