road speed above 20 km/h up to the maximum
road speed or to the set winter tyre limit.
If you fail to adapt your driving style, cruise con‐
trol can neither reduce the risk of an accident
nor override the laws of physics. It cannot take
into account road, weather or traffic conditions.
Cruise control is only an aid. You are responsible
for the distance to the vehicle in front, for vehi‐
cle speed, for braking in good time and for stay‐
ing in lane.
Displays in the multifunction display
The status of cruise control and the stored
speed are shown in the multifunction display.
1 Cruise control is selected
2 Speed is saved, cruise control is deactivated
3 Speed is saved, cruise control is activated

The segments extending from the current
stored speed to the end of the scale, or to
the set winter tyre limit, light up in the
speedometer.
System limitations
Cruise control may be unable to maintain the
stored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle. By
doing so, you will make use of the braking effect
of the engine. This relieves the load on the brake
system and prevents the brakes from overheat‐
ing and wearing too quickly.
Do not use cruise control in the following situa‐
tions:
R
In traffic situations which require frequent
changes of speed, e.g. in heavy traffic, on
winding roads.
R
On slippery roads. Accelerating can cause
the drive wheels to lose traction and the
vehicle could then skid.
R
If you are driving when visibility is poor.
Function of the limiter
The limiter restricts the speed of the vehicle. To
reduce the speed swiftly to the set speed, the
limiter applies the brakes automatically.
You can limit the speed as follows:
R
Variable: for speed limits, e.g. in built-up
areas.
R
Permanent: for long-term speed restrictions,
e.g. when driving in winter tyre mode.
