Automatic gearbox - Powershift*
An automatic gearbox with Powershift differs
from an automatic gearbox with Geartronic (p.
273), in that it has double mechanical clutch
discs.
D : Automatic gear positions. +/– : Manual gear
positions. S : Sport mode*. 12
The Powershift automatic gearbox transmits
the motive force from the engine to the drive
wheels with double mechanical clutch discs,
as opposed to Geartronic which instead uses
a conventional hydraulic torque converter.
Powershift transmission operates in the same
way and has similar controls and functions as
the Geartronic automatic transmission. One
exception is Geartronic's Winter mode, see
Automatic gearbox - Geartronic* (p. 273).
Powershift enables driving away on a slippery
road surface if 2nd gear is engaged manually
instead of 3rd gear (Geartronic).
Powershift or Geartronic
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 with very low speed.
In the event of uncertainty as to whether or
not the car is equipped with Powershift trans-
mission, this can be verified by checking the
designation on the gearbox label under the
bonnet - see Type designations (p. 438). The
designation ”MPS6” means that it is
Powershift transmission - otherwise it is
Geartronic automatic transmission.
To bear in mind
The transmission's double clutch has over-
load 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 gradi-
ent, or with a trailer hitched. The transmission
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 for-
ward a short distance, and then wait
another moment with your foot on the
brake pedal.
IMPORTANT
Use the foot brake to hold the car station-
ary on an uphill gradient - do not hold the
car with the accelerator pedal. The gear-
box could then overheat.
For important information regarding
Powershift transmission, see Towing (p. 308).
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.
