The transmission positions and current drive
program : are shown at the bottom of the
instrument cluster display. The current trans-
mission position is highlighted.
In drive program M, the transmission position
indicator shows the current gear in position D
( Y page
135).
If you restrict the shift range, the transmission
position indicator shows the current transmis-
sion position plus restricted shift range =,
e.g. D2 ( Y page 133).
The arrows in the transmission position display
show how and into which transmission posi-
tions you can change using the DIRECT
SELECT lever. Changing gear
The automatic transmission adapts to your
individual driving style by continuously adjust-
ing its shift points. These shift point adjust-
ments take into account the current operating
and driving conditions. If the operating or driv-
ing conditions change, the automatic transmis-
sion reacts by adjusting the gearshift program.
When the automatic transmission is in trans-
mission position h, it shifts the individual
gears automatically.
This depends on the following factors:
R the drive program selected ( Y page 134)
R any restriction in the shift range
(Y page

133)
R the position of the accelerator pedal
R the road speed
You can also change gear manually if you
select drive program M (Y page 135).132

WARNING
Electrostatic charging can lead to the crea-
tion of sparks and ignite fuel vapor. There is
a risk of fire and explosion.
Touch the metallic body of the vehicle
before you open the fuel filler cap or handle
the pump nozzle. Any possible electrostatic
charge present will in this way be depleted.
Do not get into the vehicle again during the
refueling process. Otherwise, electrostatic
charge could build up again. H
Environmental note
If fuels are handled improperly, they pose a
danger to persons and the environment. Do
not allow fuels to run into the sewage sys-
tem, the surface waters, the ground water or
into the ground.
! Do not switch on the ignition if you acci-
dentally refuel with the wrong fuel. Other-
wise, the fuel will enter the fuel lines. Notify
a qualified specialist workshop and have the
fuel tank and fuel lines drained completely.
! Overfilling the fuel tank could damage the
fuel system.
! Take care not to spill any fuel on painted
surfaces. You could otherwise damage the
paintwork.
