General notes
Lane Keeping Assist monitors the area in
front of your vehicle by means of a cam-
era :, at the top of the windscreen. Lane
Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally.
If you have chosen the
Display unit
Speed-/odometer: ( Y page 255) function in
the on-board computer and selected km as
the unit of measurement, Lane Keeping
Assist is active starting at a speed of
60 km/h. If the
miles display unit is selected,
the assistance range begins at 40 mph.
A warning may be given if a front wheel
passes over a lane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
