If the cruise control system is already active:

  • Press and hold –SET until the desired lower speed is reached, then release it.
  • To decrease speed in small increments, briefly press –SET. Each press reduces the vehicle speed by approximately 1 km/h.

The speedometer readout can be displayed either in English or in metric units of measurement.

See Instrument Cluster (base and middle level) or Cluster (top level). The increment value used depends on the units displayed.
