accelerate or brake unexpectedly. There is a
risk of an accident.
Take the traffic conditions into account
before calling up the stored speed. If you do
not know what the stored speed is, store the
desired speed again.

X
Remove your foot from the accelerator pedal.
Cruise control is on and, when activated for
the first time, accepts the current speed or it
adjusts the vehicle's speed to the speed
stored.
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
Press the cruise control lever up

for a
higher speed or down

for a lower speed.
X
Keep the cruise control lever pressed until the
desired speed is reached.
X
Release the cruise control lever.
The new speed is stored.

To adjust the set speed in1 km/hincre-

to the pressure point.
The last stored speed increases or decreases
in 1 km/h increments.

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. For example, if
you accelerate briefly to overtake, cruise con-
trol adjusts the vehicle's speed to the speed
stored after you have finished overtaking.
Deactivating cruise control
There are several ways to deactivate cruise con-
trol:

you apply the electric parking brake
R
you are driving at less than 30 km/h
R

Speed limiter
General notes
The speed limiter brakes automatically so that
you do not exceed the set speed. You must
select a lower gear in good time on long and
steep downhill gradients, especially if the vehi-
cle is laden or 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
prevents the brakes from overheating and wear-
ing too quickly.
You can set a variable or permanent limit speed:
R
variable for speed limits, e.g. in built-up areas
R
permanent for long-term speed restrictions,
e.g. when driving with winter tyres fitted
(

i
The speed indicated in the speedometer
may differ slightly from the limit 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 speed lim-
iter cannot take into account road, weather or
traffic conditions. The speed limiter is only an
