ning at approx. 20 mph/30 km/h. The car then
stores and maintains the speed that you specify
using the lever on the steering column.

constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise you could lose
control of the vehicle and cause an accident as a
result.<

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 briefly displayed in the instrument
cluster.
If the engine braking power is insufficient on a
downhill slope, the set speed may be exceeded.
On uphill gradients, it may prove impossible to
maintain the set speed if engine power output is
insufficient.
Increasing speed

desired speed is reached.
Each time the lever is pressed lightly, the speed
is increased by approx. 1 mph/1 km/h.
Accelerating using the lever

is reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever, arrow 2, until the
desired speed is reached.
The functions are the same as when the set
speed is increased or the vehicle is accelerated,
except that in this case the speed decreases.
Deactivating cruise control
Tap the lever upwards or downwards, arrow3.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you depress the clutch of a manual
transmission or shift to neutral
>When you select the automatic transmis-
sion's neutral position N
>When the vehicle travels faster or slower
than the set speed for an extended period,
e.g. when the accelerator is depressed
>When you activate DTC or deactivate DSC
>When DSC is intervening
Resuming a speed stored beforehand
Press the button, arrow4.
The last stored speed is resumed and main-
tained.
The stored speed is briefly displayed in the
instrument cluster.
The stored speed is cleared when the ignition is
switched off.
