– automatically after approx. 8 seconds (unless
cornering or overrunning),
– if you depress the accelerator for kickdown,
– after moving off.
Temporary change-down
Conditions: Speed is higher than approx. 33 mph
(54 km/h).
Rapid acceleration. The Tiptronic temporarily
changes to the sportiest gear-changing map,
i.e. to the highest possible gear-changing
points. Correspondingly, the transmission
shifts down immediately by one or two gears.
Ending the function:
Release the accelerator markedly (by approx.
25%).
Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to
manual mode M using the rocker switches on
the steering wheel.
For optimum acceleration, e.g. when overtak-
ing, depress the accelerator pedal beyond the
full-throttle point (kickdown).
The transmission shifts down depending on the
speed of travel and engine speed. Upward shifts
occur at the highest possible engine speeds.
These gear-changing speeds remain active until
the accelerator is released to approx. 80% of the
full-throttle position.
M - Manual selection mode
Function
The currently selected gear is retained when you
change from D to M.
If you change from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is chosen.
