Cruise control
Function of cruise control
Cruise control accelerates and brakes the vehicle
automatically in order to maintain a previously
stored speed.
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
road speed above 15 mph (20 km/h).
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 vehicle
speed, braking in good time and for staying in
your lane.
Displays in the multifunction display
The status of cruise control and the stored speed
are shown in the multifunction display.

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.
On long and steep downhill gradients, you should
change down to a lower gear in good time. Take
particular note of this when driving a laden vehi‐
cle. By doing so, you will make use of the
engine's braking effect. This relieves the load on
the brake system and prevents the brakes from
overheating and wearing too quickly.
Do not use cruise control in the following situa‐
tions:
R
In traffic situations where frequent speed
changes are required, e.g. in heavy traffic or
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.

WARNING Risk of accident due to stored
speed
If you call up the stored speed and this is
lower than your current speed, the vehicle
decelerates.
#
Take into account the traffic situation
before calling up the stored speed.
Requirements:

is activated, but may not intervene.
R
The driving speed is at least 15 mph
(20 km/h).

To activate cruise control: push rocker

up.
#
Remove your foot from the accelerator pedal.
The current speed is then saved and main‐
tained by the vehicle.

up or down.
The stored speed is increased or reduced by
1 mph (1 km/h).
