The cruise control function cannot take
account of road and traffic conditions.
Always pay attention to road and traffic
conditions, even when cruise control is
activated.Cruise control is only an aid designed to
assist driving. You are responsible for the
vehicle’s speed and for braking in good
time.
If there is a change of drivers, advise the
new driver of the cruising speed that is
stored.
Warning

Do not use cruise control:
\4if road and traffic conditions do not
permit a constant driving speed to be
maintained (e.g. heavy traffic or wind-
ing roads). You could otherwise cause
an accident.
\4on slippery roads. The drive wheels
may lose their grip when braking or
accelerating and the vehicle could
skid
\4when visibility is poor, e.g. in fog,
heavy rain or snow
iCruise control may be unable to
maintain the stored speed on uphill
or downhill gradients. The stored
speed is resumed if the gradient
evens out and the vehicle’s speed
has not fallen below 20 mph
(30 km/h).
