How intervention by Predictive Cruise Control saves fuel
Anticipating the road that lies ahead, Predictive Cruise
Control may intervene in the following ways:
Cruise Control and Downhill Speed Control settings
Temporarily allow higher or lower vehicle speeds to reduce the amount of fuel used over the total distance.
- Reduce the vehicle speed just before the top of a hill
- Allow a vehicle speed above the cruise setting before a new climb begins
- Allow a vehicle speed above the downhill speed setting at the end of a steep descent
AS Tronic shift strategy (Predictive shift)
Fuel savings from lower engine speeds.
- Shift up when acceleration in the next gear will be sufficient to reach the hill top
- Inhibit upshift in short descents (anticipating downshift at the next climb)
- Inhibit unnecessary downshift just before the top (anticipating upshift in the descent)
