during the gear-shift sequence
may cause the function to abort
and/or the gear change to fail.
No support is provided by the
gearshift assistant during gear
changes made using the clutch.
Downshifts
Downshifts are assisted up to
the speed at which the engine
reaches maximum rpm in the
gear to be engaged. Over-
revving is thus prevented.
Maximum engine speed
-1
max 12000 min
Upshifts
The gearshift assistant does
not provide added support
when the engine speed falls
below idle in the new gear.
Idle speed

Brakes
How do you achieve
the shortest stopping
distances?
The dynamic load distribution be-
tween the front and rear wheel
changes during braking. The
heavier you brake, the greater
the weight transfer to the front
wheel. Increases in the load at
an individual wheel are accom-
panied by a rise in the effective
braking force that the wheel can
provide.
To achieve the shortest possi-
ble braking distance, the front
brake must be applied quickly
and with increasing force. This
procedure provides ideal exploita-
tion of the extra weight transfer
to the front wheel. The clutch
should also be disengaged at the
same time. The frequently-prac-
ticed procedure for "panic brak-
ing", in which maximum braking
force is applied as rapidly as pos-
sible, produces deceleration rates
that rise more quickly than the
dynamic weight transfer occurs.
As a result, a complete transfer
of braking force to road surface
is not possible. This can result
in a longer braking distance. Use
both brakes. The rear wheel may
tend to lift off the ground. Lifting
off the ground is prevented by
the BMW rear wheel lift-off assis-
tant.
