Cruise C ontrol
A n y given speed above approxi­
mately 25 mph (40 km /h) can be
m aintained w ith the cruise control
by operating the sw itch.
1 = Setting (touch sw itch)
Accelerating (hold sw itch)
2 = S etting (touch sw itch)
Decelerating (hold sw itch)
Norm ally the vehicle is acceler­
ated to the desired speed w ith
the accelerator. Speed is set
by briefly pushing the sw itch
to position "1 " or “ 2 ", and the
accelerator can be released.
The speed can be increased
(e. g. fo r passing) by using the
accelerator. As soon as the ac­
celerator is released, the pre­
viously set speed w ill be re­
sumed autom atically.
If the set speed is to be in­
creased or decreased slightly
(e. g. fo r adaption to the flo w
o f tra ffic ), retain sw itch in p o ­
sition "1 " or "2 " until the de­
sired speed is reached. W hen
the sw itch is released, the
new ly set speed remains co n ­
stant.
= Cancelling
To canel the cruise control,
briefly push lever to posi­
tion
"3 ".
The cruise control w ill also be
cancelled if the brake pedal is
actuated or if the vehicle speed
drops on steep grades by
more than 20 % below the set
speed.
4 = Resume
If the lever is briefly pushed to
position "4 " w hen driving at
a speed exceeding 25 mph
(40 km /h) th at speed is
resumed w hich w as set prior
to the cancellation o f the
cruise control. The m ost re­
cently stored speed is can­
celled w hen the key in the
steering lock is reversed to po­
sition "1" or "0".
Im portant:
Please do not use the cruise con­
trol if tra ffic conditions do not
make it advisable to m aintain a
steady speed, i. e. in heavy tra ffic
or on tw istin g or slick and m uddy
roads.
Position "R esum e" should be ap­
plied only if the driver is fu lly aware
o f this speed and wishes to resume
this particular preset speed.
W hen driving w ith the cruise co n ­
trol, the selector lever m ust not be
shifted to position "N " as o ther­
wise the engine w ill speed up.
