Mercedes-Benz 190 E 2.3 1991 Owner's Manual page 66

Note:
If the engine does not brake the ve­
hicle sufficiently while driving on a
downgrade, the speed you set on the
cruise control may be exceeded and
you may have to step on the brake
pedal to slow down. As soon as the
grade eases, the cruise controlled
speed will again be maintained as
long as the brakes were not previously
applied, or the lever may be used to
resume the previously set speed if the
brakes were applied.

Warning!
Only use the cruise control if the
traffic and weather conditions
make it advisable to travel at a
steady speed.
• The use of cruise control
can be dangerous on winding
roads or in heavy traffic be­
cause conditions do not allow
safe driving at a steady speed.
• The use of cruise control can
be dangerous on slippery
roads. Rapid changes in tire
adhesion can result in wheel
spin and loss of control.
The "Resume" function should
only be operated if the driver is
fully aware of the previously set
speed and wishes to resume this
particular preset speed.
Caution!
In the case of manual transmissions,
the vehicle maximum speed in the
individual gears should not be ex­
ceeded. See line markings on the
speedometer. In the case of automatic
transmissions, the transmission selec­
tor lever must not be shifted to posi­
tion " N" when driving with the cruise
control engaged as otherwise the
engine will overrev.
