trailer stabilisation may be impaired or
inoperative in the following situations:

R
Cruise control and speed limiter
Function of cruise control
Cruise control accelerates the vehicle automat-
ically in order to maintain a previously stored
speed.
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 safe distance to the vehicle in front, for
vehicle speed, braking in good time and for stay-
ing in your lane.
You operate cruise control with the cruise con-
trol lever. You can select any road speed above
40 km/h.
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.
System limitations
Cruise control may not be able to maintain the
set speed on uphill gradients. The stored speed
is resumed when the gradient evens out.
Cruise control does not brake on downhill gra-
dients. Cruise control may not be able to main-
tain the set speed on downhill gradients.
Do not use cruise control in the following situa-
tions:
in traffic situations where frequent speed
R
changes are required, e.g. in heavy traffic or
on winding roads
on icy or slippery roads
R
Accelerating may cause the driven wheels to
lose traction and the vehicle could then skid.
if there is poor visibility

Function of the speed limiter
The speed limiter restricts the speed of the vehi-
cle.
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. It cannot take
into account road, weather or traffic conditions.
The speed limiter is only an aid. You are respon-
sible for the safe distance to the vehicle in front,
for vehicle speed, braking in good time and for
staying in your lane.
You can operate the variable speed limiter with
the cruise control lever. You can select any road
speed above 30 km/h.
Kickdown
The variable speed limiter switches to passive
when you depress the accelerator pedal (kick-
down). The
Limiter passive
Limiter passive
appears in the multifunction display.
After completion of kickdown, the variable
speed limiter is activated again in the following
situations:
if the driven speed drops below the stored
R
speed
if the stored speed is called up
R
if you store a new speed
R
System limitations
The speed limiter does not brake on downhill
gradients. The speed limiter may exceed the set
speed on downhill gradients. If the set speed is
exceeded by more than 10 km/h for longer than
ten seconds, you will hear an audible warning
and a message will appear in the multifunction
display (
page 124).

WARNING
If you call up the stored speed and this differs
from your current speed, the vehicle will
accelerate. If you do not know the stored
speed, the vehicle can accelerate unexpect-
edly. There is a risk of an accident.
Before you call up the stored speed, pay atten-
tion to traffic conditions. If you do not know
the stored speed, store the desired speed
again.
