Audi A8   Controls   Automatic gearbox  tiptronic
The downhill speed control function helps the driver when driving down steep gradients.
Downhill speed control is activated on a downhill gradient when the selector lever is in D/S and the driver presses the brake pedal. The gearbox automatically selects a suitable gear for the gradient. The downhill speed control function attempts to maintain the speed at which the vehicle was travelling when the foot brake was applied (subject to the laws of physics and technical limitations of the power train). It may be necessary to adjust the speed again using the brake pedal.
Downhill speed control is deactivated as soon as the road levels out again or you press the accelerator pedal.
When you activate the cruise control system Link, downhill speed control is also activated when you set a cruising speed.
WARNING!
The downhill speed control function cannot defy the laws of physics and may therefore not be able to maintain a constant speed in certain circumstances. Always be prepared to use the brakes!
