BMW R 1250GS Adventure Rider's Manual page 161

ABS brake system, without the
rider having to continuously op-
erate the brake lever. When Hill
Start Control is activated, pres-
sure builds in the rear brake sys-
tem so that the motorcycle re-
mains stationary on a sloping sur-
face.
The brake pressure in the brake
system depends on the gradient.
Influence of gradient on
brake pressure and starting
behavior
Stopping on a slight incline
builds up only a small amount
of brake pressure. The brake
is released quickly when driving
off, making it possible to drive
off more smoothly. Additional
turning of the throttle grip is
hardly necessary.
Stopping on a steeper slope
increases the amount of brake
pressure built up. The brake
is a bit slower to release when
driving off. More torque is re-
quired to drive off, making ad-
ditional turning of the throttle
grip necessary.
Behavior when the vehicle is
rolling or slipping
The brake pressure increases
when the vehicle is rolling with
Hill Start Control active.
If the rear wheel slips, the
brake is released again after
approx. 1 m. This prevents the
vehicle from rolling with the
rear wheel blocked.
Releasing the brake when
switching off the engine or
during timeout
Hill Start Control is deactivated
when the engine is switched off
using the emergency-off switch,
when the side stand is folded
out, or after it times out (10 min-
utes).
In addition to the indicator and
warning lights, the rider is to be
made aware about the deactiva-
tion of the Hill Start Control by
the following behavior:
Brake warning jerk
The brake is released briefly
and is immediately reactivated.
This causes a jerking behavior
that the driver can feel.
The partial integral ABS brake
system sets a speed of approx.
1-2 km/h.
The driver must brake the vehi-
cle manually.
After two minutes, or when the
brake is applied, Hill Start Con-
trol is deactivated completely.
NOTICE
When the ignition is switched off,
the holding pressure is built up
immediately and without brake
warning jerk.
