Cruise Control; Cruise Control Lever - BMW 840Ci Owner's Handbook Manual

Cruise control

72
Any desired road speed above
approx. 40km/h can be memorised
and maintained automatically.
The memorised speed value is lost
when the engine is switched off.
1 Acceleration
Moving the lever briefly:
The car's actual speed is maintained
and memorised. Each time the lever is
moved briefly to this position again,
road speed is increased by app. 1km/h.
Holding the lever in this position:
The car accelerates without the accel-
erator pedal being touched. When the
switch is released, the speed then
reached is maintained and memorised.
2 Deceleration
Holding the lever in this position:
The car decelerates by automatic
restriction of the throttle, provided it
was previously travelling at a control-
led speed. When the switch is
released, the speed then reached is
maintained and memorised.
Moving the lever briefly:
Each time the lever is moved briefly,
the road speed is reduced by app.
1km/h if it was previously travelling at
a set speed.
3 Recall
Moving the lever briefly:
The speed last memorised is recalled
and maintained once it has been
reached again.
4 Off
Moving the lever briefly:
the cruise control facility is switched
off immediately.
The cruise control is also switched off
automatically:
d If the car exceeds the selected
speed by app. 16km/h (10 mile/h)
d If the car's road speed falls more
than 8km/h (5 mile/h) below the
selected speed
d If a high rate of deceleration
occurs (above 1.5m/sl), for exam-
ple on a steep hill, when braking
and declutching or if the automatic
transmission selector lever is
moved from D to N.
a
Do not use the cruise control on
twisting roads, if traffic is heavy or in
any other situation which makes it too
difficult to maintain a constant speed,
nor when the road could be slippery
(snow, rain or ice) or on a loose sur-
face (stone chippings or sand). In
such situations, the car's behaviour
will not be sufficiently flexible to take
road and traffic conditions into
account.c
