Cruise control is not deactivated if you
depress the accelerator pedal. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the last
speed stored after you have finished overtak-
ing.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:

while driving a vehicle with manual transmis-
sion, you shift into neutral or depress the
clutch pedal for longer than six seconds
R
on vehicles with manual transmission, you
shift to a gear that is too high, and as a result
the engine speed is too low
R
on vehicles with automatic transmission, you
shift to position

Speed limiter
General notes
The speed limiter restricts the vehicle speed.
The speed limiter brakes automatically to
quickly regulate the stored speed.
You must select a lower gear in good time on
long and steep downhill gradients, especially if
the vehicle is laden or towing a trailer. For vehi-
cles with automatic transmission, you need to
shift manually using the steering wheel gearshift
paddles. 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 wearing too
quickly.
You can set a variable or permanent limit speed:
R
Variable for a maximum permissible speed,
e.g. in built-up areas
R
Permanent for restriction of the maximum
speed for technical reasons, such as when
driving on winter tyres (
Y
page 180)
i
The speed indicated in the speedometer
may differ slightly from the maximum permis-
sible speed stored.
Important safety notes
If you fail to adapt your driving style, the speed
limiter can neither reduce the risk of an accident
nor override the laws of physics. The limiter can-
not take into account road, weather or traffic
conditions. The limiter 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 a new driver takes over, advise the new driver
of the speed stored.
