Speed control cruise control
Function of cruise control
Cruise cont rol accelerates and brakes theve hi‐
cle automatically in order tomaintain a pr evi‐
ously stored speed.
If yo u accelerate toove rtake, forex ample, the
st ored speed is not dele ted. If youre mo veyour
fo ot from the accelerator pedal af terove rtaking,
cruise control will resume speed regulation back
to thestored speed.
Yo u can operate cruise cont rol with the cruise
control le ver.
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 rth e dis tance totheve hicle in front, forve hi‐
cle 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 braking ef fect
of the engine. This relie vesth e load on the brake
sy stem and pr events the brakes from overheat‐
ing and
wearin
g tooqu ickl y.
Do not use cruise control in thefo llowing situa‐
tions:
RIn traf fic situations whi chrequ ire frequent
ch anges of speed, e.g. in heavy traf fic, on
winding roads.
ROn slippery roads. Accelerating can cause
th e drive wheels tolose traction and the
ve hicle could then skid.
RIfyo u are driving when visibility is poor.
