Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed on the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow 1, until the desired
speed is reached.
> Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
> Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.
Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
> Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
> Each time the lever is pulled beyond the
resistance point, the desired speed is
reduced by up to 5 mph o r 10 km/h until the minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow 3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
> When you brake the vehicle
> When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
> When you engage selector lever position N
in cars with an automatic transmission
> When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
> When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC.
> When DSC or ABS is intervening
Cruise control is not de activated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the st ored speed is achieved
again and maintained.

example, when cruise control has
been deactivated as a result of DSC
intervention. A message appears on the Control
Display.
Deactivating the system
