Roptimal fuel consumption resulting from theautomatic transmission shifting up sooner.
Rthe vehicle pulls away more gently in forwardand reverse gears, unless the acceleratorpedal is depressed fully.
Rthe vehicle has improved driving stability, forexample on slippery road surfaces.
Rthe automatic transmission shifting upsooner. This results in the vehicle being drivenat lower engine speeds and the wheels beingless likely to spin.
Rgliding mode is activated automatically whenengine-internal conditions are fulfilled andthe accelerator is not depressed. At the sametime the transmission’s clutch opens and thevehicle rolls freely using its kinetic energy. Asa result great distances can be completedwithout the engine brake and fuel consump-tion reduced.
iThe availability of gliding mode depends onvarious factors, including the following:
Rthe engine and transmission temperature
Rthe downhill gradient
Rthe vehicle speed
Rperforming regular adaptation functions
When you depress the brake pedal, glidingmode is deactivated, depending on pedalpressure.
When you activate cruise control or ActiveDistance Assist DISTRONIC, gliding mode isnot available.
