WARNING
If it is impossible to drive with sufficient brak-
ing distance and at a constant speed, using
the cruise control system may cause acci-
dents and serious injuries may occur.
●
Do not use Travel Assist when visibility is
bad, on steep roads, on windy roads or in slip-
pery circumstances (such as snow, ice, rain or
loose gravel), or on flooded roads.
●
Only use the cruise control system on
paved roads with a firm surface.
●
Adapt your speed and safety distance to
the vehicle in front of you at all times to suit
the visibility, weather, road and traffic condi-
tions.
●
After use, always switch off the speed lim-
iter to prevent the speed being regulated
against your wishes.
●
It is dangerous to use a set speed which
is too high for the prevailing road, traffic or
weather conditions.
