4Resuming a speed stored beforehand
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, arrow1, 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, 
until the desired speed is reached.
Accelerating significantly:Press the lever beyond the resistance point, 
arrow 1, 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 
re duc e d by up to 5 mph or 10 k m/h until the 
minimum speed of 20 mph or 30 km/h is 
achieved.
The system stores and maintains the speed.
Deactivating cruise control
Tap the lever upwards or downwards, arrow3. 
The displays on the speedometer disappear.
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 manual transmission
>When you select the automatic transmis-
sion's neutral position N
>When you activate DTC or deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing 
the accelerator pedal. Once the accelerator 
pedal is released, the stored speed is achieved 
again and maintained.
Warning lamp
The warning lamp lights up when 
cruise control is deactivated due to 
control intervention by the DSC, for 
example. A message appears on the Control 
Display.
