Setting a speed
Bear in mind that it may take a brief moment
until the vehicle has accelerated or braked to
the set speed.

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.

The new speed is stored.
To adjust the set speed in 1 km/h incre-
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 in 10 km/h incre-
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.

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
on vehicles with automatic transmission, you

The last speed stored is cleared when you
switch off the engine.
SPEEDTRONIC
General notes
SPEEDTRONIC brakes automatically so that you
do not exceed the set speed. Change into a
lower gear in good time on long and steep down-
hill 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 overheating and wear-
ing too quickly.
Important safety notes
If you fail to adapt your driving style, SPEED-
TRONIC can neither reduce the risk of an acci-
dent nor override the laws of physics. SPEED-
TRONIC cannot take into account road, weather
or traffic conditions. SPEEDTRONIC is only an
aid. You are responsible for the distance to 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
