Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.
Press the cruise control lever up : for a
X
higher speed or down ? for a lower speed.
Keep the cruise control lever pressed until the
X
desired speed is reached.
Release the cruise control lever.
X
The new speed is stored.
To adjust the set speed in1 km/hincre-
X
ments: briefly press the cruise control lever
up : or down ? to the pressure point.
The last stored speed increases or decreases
in 1 km/h increments.
To adjust the set speed in10 km/hincre-
X
ments: briefly press the cruise control lever
up : or down ? beyond the pressure point.
The last stored speed increases or decreases
in 10 km/h increments.

Cruise control is not deactivated if you
depress the accelerator pedal. If you acceler-
ate to overtake, cruise control adjusts the
vehicle's speed to the last speed stored after
you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:
Briefly press the cruise control lever forwards

cator lamp ; in the cruise control lever is on.
Cruise control is automatically deactivated if:
you apply the electric parking brake
R
you are driving at less than 30 km/h
R
®
ESP
engages or you deactivate ESP
R
while driving a vehicle with manual transmis-
R
sion, you engage neutral or depress the clutch
pedal for longer than six seconds
on vehicles with manual transmission, you
R
shift to a gear that is too high, and as a result
the engine speed is too low
in vehicles with automatic transmission, you
R
shift to position N while driving
If cruise control is deactivated, a warning tone
sounds. You will see the
message on the multifunction display for
approximately five seconds. The message on
the multifunction display disappears and the
segments on the speedometer go out.
i
The last speed stored is cleared when you
switch off the engine.
SPEEDTRONIC
General notes
SPEEDTRONIC is used to set a speed limit for
your vehicle. If the vehicle speed exceeds the
set speed limit, SPEEDTRONIC brakes automat-
ically. Shift to a lower gear in good time on long
and steep downhill gradients. Take particular
note of this when driving a laden vehicle and
when towing a trailer. By doing so, you will make
use of the braking effect of the engine. This
relieves the load on the brake system and pre-
vents the brakes from overheating and wearing
too quickly.
Important safety notes
SPEEDTRONIC can neither reduce the risk of an
accident if you fail to adapt your driving style nor
override the laws of physics. SPEEDTRONIC
cannot take into account road, weather or traffic
conditions. SPEEDTRONIC is only an aid. You
are responsible for maintaining a safe distance
from the vehicle in front, for vehicle speed, for
braking in good time and for staying in lane.
If there is a change of drivers, advise the new
driver of the speed stored.
You can set a variable or permanent limit speed:
variable for speed limits, e.g. in built-up areas
R
®
permanent for long-term speed restrictions,
R
e.g. when driving with winter tyres fitted

The speed indicated in the speedometer
may differ slightly from the limit speed stored.
