for “normal” driving. The gears
are shifted automatically according to the acceler-
ator position and speed.
Depending on the way the vehicle is driven and on
the resistance (e.g. uphill), the gear-changing
points are shifted towards higher or lower engine-
speed ranges.
The accelerator position, driving speed, engine
speed, longitudinal and lateral acceleration and
the road profile all have an influence on the gear-
changing characteristic.
Unwanted upward shifts, e.g. before bends, are
prevented by swiftly releasing the accelerator
pedal.
Depending on lateral acceleration, upward
changes on bends are not made until the engine-
speed limit is reached.
Under braking, and depending on the amount of
deceleration, the Tiptronic changes down earlier.
For subsequent cornering, the right gear is
engaged when pressure is applied to the brakes
before the bend. The bend is taken in the right
gear, and when you accelerate out of the bend you
do not have to change down.
Sport mode switched on
f Please observe the chapter “SPORT MODE” on
page 46.
If the Sport mode programme is switched on,
Tiptronic switches to a sporty gear-changing map
and shortens the shifting times.
Deceleration downshifts are commenced earlier.
Downshifts are already carried out in the case of
slight decelerations, even at higher engine
speeds.
