Powershift transmission operates in the same way and has similar controls and functions as the Geartronic automatic transmission.
One exception is the function "Geartronic - Winter mode":
- Powershift enables driving away on a slippery road surface if 2nd gear is engaged manually - instead of 3rd gear with Geartronic.
Towing
The model with Powershift transmission should not be towed as it is dependent on the engine running in order to receive sufficient lubrication. If towing still has to take place, the route must be as short as possible and then at very low speed.
In the event of uncertainty as to whether the car is equipped with Powershift or Geartronic transmission, this can be verified by checking the designation on the gearbox label under the bonnet, Type designations. The designation ”MPS6” means that it is Powershift transmission - otherwise it is Geartronic automatic transmission.
See also important information in section Towing.
To bear in mind
The transmission's double clutch has overload protection that is activated if it becomes too hot, e.g. if the car is held stationary with the accelerator pedal on an uphill gradient for a long time.
Overheated transmission causes the car to shake and vibrate, and the warning symbol illuminates and the combined instrument panel shows a message. The transmission can also overheat during slow driving in queues (10 km/h or slower) on an uphill gradient, or with a trailer hitched. The gearbox cools down when the car is stationary, with foot brake depressed and the engine running at idling speed.
Overheating during slow driving in queues can be avoided by driving in stages:
- Stop the car and wait with your foot on the brake pedal until there is a moderate distance to the traffic ahead, drive forward a short distance, and then wait another moment with your foot on the brake pedal.
Important
Text message and action
In some situations the combined instrument panel may show a text message at the same time as a symbol is illuminated.
| Symbol | Message | Driving characteristics | Action |
|---|---|---|---|
 | Transmission hot Brake to hold | Difficulty in maintaining even speed at constant engine speed. | Transmission overheated. Keep the car stationary using the foot brake.1 |
 | Transmission hot Park safely Let engine run | Significant pulling in the car's traction. | Transmission overheated. Park the car immediately in a safe manner.1 |
| Transmission cooling Let engine run | No drive due to overheated gearbox. | Transmission overheated. For fastest cooling: Run the engine at idling speed with the gear lever in the N or P position until the message clears. |
The table shows three steps with an increased degree of seriousness should the transmission become too hot. In parallel with the text message, the driver is also advised that the car's electronics are temporarily changing the driving characteristics. Follow the instructions in the text message where appropriate.
Note
Warning
For more possible text messages with their respective proposals for solutions concerning automatic gearbox, see Messages.
A text message extinguishes automatically after the action has been carried out or after one press on the indicator stalk OK button.
