The kick-down feature is designed to give maximum acceleration.
Applies to vehicles with multitronic gearbox
When the accelerator pedal is pressed right down past the point of resistance at full throttle, the gearbox will select a lower gear ratio, depending on road speed and engine speed. While you keep the accelerator depressed the engine speed is automatically controlled to give your vehicle maximum acceleration.
Applies to vehicles with S tronic or tiptronic gearbox
When the accelerator pedal is pressed right down past the point of resistance at full throttle, the gearbox will shift down to a lower gear, depending on road speed and engine speed. The upshift to the next higher gear is delayed until the engine reaches maximum rpm.
WARNING!
Please note that if the road surface is slippery or wet, the kick-down feature could cause the driving wheels to spin, which could result in skidding.
