R Intheeve nt of se vere swerving, the engine
output is also reduced and all wheels are

Cruise contro l is operated using the cor respond‐

speed abo
ve20 km/h up tothe maximum speed
or up tothe set winter tyre limit.
If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident
nor override the la wsof ph ysics. It cannot take
into account road, weather or traf fic conditions.
Cruise control is only an aid. You are responsible
fo r maintaining a safe dis tance totheve hicle in
front, forve hicle speed, for braking in good time
and forst ay ing in lane.

Sy stem limitations
Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed when the gradient evens out.
Change into a lo werge ar in good time on long
and steep downhill gradients. Take particular no
te ofthis when driving a laden vehicle. By
doing so, you will make use of the engine's brak‐
ing ef fect. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and wearing tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
R In traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
R On slippe ryroads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
R Ifyo u are driving when visibility is poor.
Fu nction of the limiter
The limiter restricts the speed of theve hicle. To
re duce the speed tothe set speed, the limiter
applies the brakes automaticall y.
Yo u can limit the speed as follo ws:

areas.
R Perm anen t:for long-term speed restrictions,

of fatigue or increasing lapses in concentration
on the part of the driver, it suggests taking a
brea k.
AT TENTION ASSIST is only an aid. It cannot

ta ke regular breaks in good time that allow for
adequate recuperation.
Yo u can choose between two settings.
R Standard: normal sy stem sensitivity.
R Sensitive: higher system sensitivity. The
