To store and maintain speed or to
accelerate
You can maintain and store any desired
vehicle speed above approx. 20 mph /
30 km/h.
Press the lever briefly in direction 1:
The system maintains and stores the cur-
rent vehicle speed. Every time you tap the
lever, the speed increases by approx.
0.6 mph / 1 km/h.
Hold the lever in position 1:
The vehicle accelerates without pressure
on the accelerator pedal. As soon as you
release the lever, the system stores and
maintains the current speed.
If, on a downhill grade, the engine
braking effect is not sufficient, the
controlled speed can be exceeded. Speed
can drop on uphill grades if the engine out-
put is insufficient.<
To decelerate
Press the lever briefly in direction 2:
When the cruise control is active, vehicle speed is reduced by approx. 0.6 mph /
1 km/h every time you tap the button.
Hold the lever in position 2:
With the cruise control active, the system
automatically reduces the throttle opening
to slow the vehicle. As soon as you release
the lever, the system stores and maintains
the current speed.
To recall the stored setting
Press the lever briefly in direction 3:
The vehicle accelerates to and maintains
the last speed stored.
To deactivate the system
Press the lever briefly in direction 4:
The cruise control is deactivated immedi-
ately.
Cruise control is also deactivated when the
ignition key is turned to position 0.
In addition, the system is automatically
deactivated in response to the following
conditions:
>When you apply the brakes
>When you depress the clutch or move
the automatic selector lever from D to N
>If you exceed or fall below the preset
speed for an extended period – by
depressing the accelerator, for exam-
ple.
The stored speed is cleared in all three
cases.
