st ored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour

Cruise contro l is operated using the cor respond‐

If yo ufa ilto adapt your driving style, cruise con‐
trol can neither reduce therisk of an accident nor

Sy stem limitations
Cruise control may be unable tomaintain the

speed is resumed when the gradient evens out.
On long and steep downhill gradients, you should
ch ange down toa lo werge ar in good time. Take

Do not use cruise control in thefo llowing situa‐

R In traf fic situations whe refrequent speed
ch anges are requ ired, e.g. in heavy traf fic or
on winding roads.
R On slippe ryroads. Accele rating can cause the

R When driving with a trailer, check at regular

R The vehicle/trailer combination is heavier,
