If the car cannot be driven, e.g. due to a flat
battery, the gear selector must be moved
from the P position so that the car can be
moved.
Lift the rubber mat in the compartment
behind the centre console and locate a

hole
for the key blade
in the bottom of
the compartment.
Search for a spring-loaded button down
in the hole with the key blade; depress
the button with the blade and hold.
Move the gear selector from the P posi-
tion and pull up the key blade.

There may be 2 holes - one for the key blade and one that fixes the rubber mat.

For information on the key blade, see page 48.
One exception is the heading "Geartronic - Winter mode": Powershift enables driving away on a slippery road surface if 2nd gear is engaged manually - not 3rd gear.

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 hydraulic torque converter.
Powershift transmission operates in the same

way
and has similar controls and functions
as the Geartronic automatic gearbox descri-
bed in the previous section.
Powershift or Geartronic?
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 page 392. The designa-
tion "MPS6" means that it is Powershift trans-
mission - 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-
