and inter vene if necessa ry. Be aware of the limi‐
ta tions rega rding the safe use of these sy stems.
Driving sy stems can neither reduce therisk of
accident if youfa ilto adapt your driving style nor
ove rride the la wsof ph ysics. They cannot alw ays

Cruise control may be unable tomaintain the
st ored speed on uphill gradients. The stored
speed is resumed if the uphill gradient evens out
and theve hicle's speed does not fall below
30 km/h.
On long and steep downhill gradients, you should

R in traf fic situations whe refrequent speed
ch anges are required, e.g. in heavy traf fic or

R off-road or on con stru ction sites
R on slippe ryor slick roads, as the drive wheels
