Maintaining speed, storing speed, and
accelerating
Press the lever up to the resistance point 1:
The system maintains and stores the current
vehicle speed. The display
1 in the speedome-
ter indicates this regulated speed, refer to the
section below. Every time you briefly press the
lever, the vehicle speed increases by roughly
1 mph/1 km/h.
Press the lever up to the resistance point and
hold it:
The vehicle accelerates without pressure on
the accelerator pedal. The system maintains
and stores your current speed as soon as you
release the lever.
Press the lever beyond the resistance point:
The speed increases by 5 mph/10 km/h.
The vehicle may accelerate beyond the regu-
lated speed on steep downhill stretches where
the engine's braking effect alone may not be
sufficient to slow the vehicle. Speed can drop
on uphill grades if the engine output is insuffi-
cient.
Maintaining speed, storing speed, and
decelerating
Pull the lever 2:
Functions are the same as 1, only the vehicle
speed is reduced.
Interrupting cruise control
With the cruise control active, briefly press the
lever up or down
3.
Cruise control is also interrupted automatically
> when you apply pressure to the brake pedal
> when you press down the clutch pedal or
engage position N of the automatic trans-
mission/SMG
> when DSC comes on
Recalling stored speed
Briefly press button 4: the vehicle accelerates
to and maintains the stored speed.
Deactivating system
When the ignition is switched off, the system is
deactivated and the stored speed is deleted.

Active cruise control*
The concept
With active cruise control, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active cruise control is a technological advance
over the familiar cruise control and is a welcome
relief from the constant adjustment of speed
that can accompany driving in traffic on free-
ways or other high-speed thoroughfares. Espe-
