speed for ap rolonged period. You can store any
road speed above 20 mph (30 km/h).
Important safety notes If you fail to adap ty our driving style, cruise con-
trol can neither reduce the risk of an accident
nor override the laws of physics. Cruise control
cannot take into account the road, traffic and
weather conditions. Cruise control is only an
aid. You are responsible for the distance to the
vehicle in front ,f or vehicle speed, for braking in
good time and for staying in lane.
Do not use cruise control: R
in road and traffic conditions which do not
allow you to maintain ac onstant speed e.g. in
heavy traffic or on winding roads R
on slippery road surfaces. Braking or accel-
erating could cause the drive wheels to lose
traction and the vehicle could then skid R
when there is poor visibility, e.g. due to fog,
heavy rain or snow
If there is ac hange of drivers, advise the new
driver of the speed stored.
