Controls
Cruise Control
Any given speed above approxi­
mately 40 km/h/25 mph can be
maintained with the cruise control
by operating the switch.
1 Setting (briefly push switch)
Accelerating (hold switch)
2 Setting (briefly push switch)
Decelerating (hold switch)
Normally the vehicle is accelerated
to the desired speed with the acce­
lerator. Speed is set by briefly
pushing the switch to position 1 or
2. The accelerator can then be
released. The speed can be
increased (e. g. for passing) by
using the accelerator. As soon as
the accelerator is released, the pre­
viously set speed will be resumed
automatically.
If a set speed is to be increased or
decreased slightly, e. g. to adapt to
the traffic flow, hold switch in posi­
tion 1 or 2 until the desired speed
is reached. When the switch is
released, the newly set speed
remains.
3 Cancelling
To cancel the cruise control,
briefly push lever to position 3.
When you step on the brake
pedal or the vehicle speed falls
below approx. 40 km/h/25 mph,
for example when driving
upgrade, the cruise control will
be cancelled.
4 Resume
If the lever is briefly pushed to
position 4 when driving at a
speed exceeding 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 cancelled
when the key in the steering
lock is turned to position “ 1” or
“
0
” .
Note:
If the engine does not brake the
vehicle sufficiently while driving on
a downgrade the speed you set on
the cruise control may be exceed­
ed 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.
Important:
Only use the cruise control if the
traffic conditions make it advisable
to travel at a steady speed.
Position “ Resume" should be
engaged only if the driver is fully
aware of the previously set speed
and wishes to resume this particu­
lar 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.
