Reducing Speed While Using Cruise Control
If the cruise control system is already activated:
• Move the thumbwheel toward SET/− and hold until the desired lower speed is reached, then release it.
• To slow down in small amounts, move the thumbwheel toward SET/− briefly and then release it.
Each time this is done, the vehicle goes about 1.6 km/h (1 mph) slower.
