– if you depress the accelerator to kickdown,
– after moving off.
Temporary change-down
Conditions: Speed is higher than approx.33 mph
(54 km/h).
Depress accelerator quickly. The Tiptronic
changes temporarily 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.
Kickdown
The kickdown function is active in selector lever
position D, even if you temporarily change to
manual mode M using the toggle 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
wide open throttle position.

Shifting Gear
M - Manual Selection Mode
Mode of operation
The currently selected gear is retained if you
change from D to M.
If you shift from M to D, the gear-changing map
suitable for your current driving style is selected
and the appropriate gear is selected.
Warning!
The kickdown function is not active in manual
selection mode "M".
Therefore shift down manually when accelerat-
ing (e.g. to overtake).
Two toggle switches in the upper steering-wheel
spokes let you comfortably and reliably select the
five forward gears.
Shifting up
Press upper part (+) of a toggle switch.
Shifting down
Press lower part (-) of a toggle switch.
Depending on driving speed and engine speed,
you can shift up or down at any time. Gear changes
which would exceed the upper or lower engine-
speed limit are not executed by the controller.
You can shift down two gears at once by quickly
pressing the toggle switches twice.
If the engine-speed limit is reached, an auto matic
upward shift is performed or, just before idling
speed is reached, a downward shift is performed.
Select an appropriately low gear on upward
and downward slopes. This will ensure
optimum use of engine power and engine
braking.
