control
General notes Cruise
controlmaintains aconst antroad
speed foryou. Itbrakes automaticall yin order
to avoid exceeding thesetspeed. Onlong and
steep downhill gradients, especiallyifthe vehi-
cle isladen, youmust select alower gearin
good time. Bydoing so,you willmake useof
the braking effectofthe engine. Thisrelieves
the load onthe brake system andprevents the
brakes fromoverheating andwearing too
quickly.
Use cruise controlonly ifroad andtraffic con-
ditions makeitappropria teto maintain a
steady speedforaprolonged period.Youcan
store anyroad speed above20mph
(30 km/h ).
Importa ntsafety notes If
you failtoadap tyour driving style,cruise
cont rolcan neither reducetherisk ofan acci-
dent noroverride thelaws ofphysics. Cruise

Do not use cruise control:
R in road andtraffic conditions whichdonot
allow youtomaintain aconst antspeed e.g.
