If the cruise control system is already activated:

  • Press and hold –SET until the desired lower speed is reached, then release it.
  • To slow down in small increments, briefly press –SET. For each press, the vehicle goes about 1 km/h (1 mph) slower.

The speedometer reading can be displayed in either English or metric units.
