The
automatic
clutch
system
(ACS)
The
"ACS"
eliminates
the
drivers clutch pedal by automatically controlling
the
clutch during
take up
from
rest, gear shifting and slowing down.
The
clutch
is
also controlled
to
provide engine braking and
tow
starting.
Clutch control
is
achieved simply through
use
of
the
accelerator pedal and gear shift lever.
The
clutch
is
disengaged whilst
the
vehicle
is
stationary and
in
gear.
Take
up
is
controlled by
the
driver
who
engages a gear
(R,
Ist
or
2nd) and then depresses
the
accelerator pedal
to
raise
the
engine speed.
Take up engine speed increases
with
the
amount
of
throttle
applied.
When
the
vehicle
is
running,
the
gear shift
is
performed simply by operating the gear lever.
