Introduction
The vehicle is equipped with an electronically controlled continu-
ously variable transmission (multitronic
automatics, the gear ratios are not shifted in fixed steps but contin-
uously variable. This gives smoother transmission and makes for
better fuel economy.
The gearbox selects the gear ratio and shifts up or down automati-
cally according to the gear change programmes stored in the
control unit ⇒ page 133, "Dynamic gear control program (DCP)".
The gearbox also has the tiptronic manual shift feature. This system
allows the driver to select gears manually if required ⇒ page 134.
Please note that on vehicles with a multitronic gearbox, torque is
transmitted via a multi-plate clutch, and not via a torque converter
as on conventional automatics. This means that the car will not
"creep" as much as conventional automatics when the engine is
idling if you stop temporarily with the selector lever in position D, S
or R.
Applies to vehicles: with multitronic®
