Cruise Control

Any given speed above approximately
40 km/h (25 mph) can be maintained
with the cruise control by operating
the lever.
1 Accelerate and set:
Lift lever briefly to set speed.
Hold lever up to accelerate.
2 Decelerate and set:
Depress lever briefly to set speed.
Hold lever down to decelerate.
Normally the vehicle is accelerated to
the desired speed with the accelera­
tor. Speed is set by briefly pushing
the lever to position 1 or 2. The acce­
lerator can be released.
The speed can be increased (e. g. for
passing) by using the accelerator. As
soon as the accelerator is released,
the previously set speed will be re­
sumed automatically.
If a set speed is to be increased or
decreased slightly, e. g. to adapt to
the traffic flow, hold lever in position
1 or 2 until the desired speed is
reached. When the lever is released,
the newly set speed remains.
3 Cancelling
To cancel the cruise control,
briefly push lever to position 3.
9708
When you step on the brake pedal
or the vehicle speed falls below
approx. 40 km/h (25 mph), for ex­
ample when driving upgrade, the
cruise control will be cancelled.
4 Resume
If the lever is briefly pulled to posi­
tion 4 when driving at a speed ex­
ceeding approximately 40 km/h
(25 mph), the vehicle resumes the
speed which was set prior to the
cancellation of the cruise control.
The last memorized speed is can­
celled when the key is turned to
steering lock position 1 or 0.
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. As
soon as the grade eases, the cruise
controlled speed will again be main­
tained as long as the brakes were not
applied.
If the set speed was sufficiently ex­
ceeded such that the brakes had to
be applied, the cruise control can be
resumed by pulling the lever to posi­
tion 4.
Warning!
Only use the cruise control if the
traffic and weather conditions ma­
ke it advisable to travel at a steady
speed.
Position "Resume" should be enga­
ged only if the driver is fully aware
of the previously set speed and
wishes to resume this particular
preset speed.
When driving with the cruise con­
trol, the transmission selector lever
must not be shifted to position "N"
as otherwise the engine will over­
rev.
