multifunction display.
Speed control cruise control
Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
If you accelerate to overtake, for example, the
stored speed is not deleted. If you remove your
foot from the accelerator pedal after overtaking,
cruise control will resume speed regulation back
to the stored speed.
Cruise control is operated using the correspond‐
ing steering wheel buttons. You can store any
speed above 15 mph (20 km/h) up to the maxi‐
mum speed.
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. The driver is
responsible for maintaining a safe distance to
the vehicle in front, for vehicle speed, for braking
in good time and for staying in lane.
Displays on the multifunction display
The status of cruise control and the stored
speed are shown in the multifunction display.

The segments between the stored speed and
the end of the segment display light up in
the speedometer.
System limits
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.
