Reducing Speed While Using Cruise Control

If the cruise control system is already activated:

• Press and hold the SET– button on the steering wheel until the lower speed desired is reached, then release it.

• To slow down in small amounts, press the SET– button briefly.

Each time this is done, the vehicle goes about 1.6 km/h (1 mph) slower.
