Further information on driving safety systems (Y page7 7). Cruise control
General notes Cruise control maintains
aconstant road
spee dfor you.Itb rakes automatically in order
to avoi dexceeding the set speed. You must
select alow gearing ood time on long and
steep downhill gradients, especially if the
vehicl eisladen or towing atrailer. By doing
so, you willm ake use of the braking effect of
the engine. This relieves the loadont he brake
system and prevents the brakes from over-
heating and wearing too quickly.
Use cruise control only if road and traffic con- ditions are appropriate for maintaining a
stead yspee dfor ap rolonged period. You can
store any road spee dabove 30 km/h.
Important safety notes If you fail to adapt yourd
riving style,cruise
control can neither reduce the risk of an acci-
dent nor overrid ethe lawsofp hysics. Cruise
control cannot take into account road,
weather or traffic conditions. Cruise control is only an aid.Y ou are responsibl efor the dis-
tance to the vehicl einfront, for vehicl espeed,
for braking in good time, and for staying in the lane.
Do not use cruise control:
R in road and traffic conditions which do not
allow you to maintai naconstant speed
(e.g. in heavy traffic or on winding roads)
R on smooth or slippery roads. Braking or
accelerating can caus ethe drive wheels to
lose traction and the vehicl ecouldt hen
skid
R when there is poor visibility, e.g. due to fog,
heavy rain or snow If there is
achange of drivers, advise the new
drive rofthe spee dstored.
