Reverse gear inhibitorThe reverse gear inhibitor hinders the possibil-
ity of mistakenly attempting to engage reverse
gear during normal forward travel.
•Follow the gearing pattern printed on the
gear lever and start from neutral position,
N before moving it to R position.
•Only engage reverse gear when the car is
stationary.
NOTE
With the upper variant of the shifting pattern
for 6-speed gearbox (see previous illustra-
tion) - first press down the gear lever in the
N position in order to engage reverse gear.
Automatic gearbox Geartronic*
D: Automatic gear positions. +/–: Manual gear
positions.
The information display shows the position of
the gear selector using the following indica-
tions:
P, R, N, D, S, 1, 2, 3, 4, 5 or 6, see
page 71.
Gear positions
Parking position - P
Select P when starting the engine or when the
car is parked. The brake pedal must be
depressed to disengage the gear selector from
the P position.
The gearbox is mechanically blocked when the
P position is engaged. Apply the parking brake
as well, as a precaution - see page 137.
NOTE
The gear selector must be in P position to
allow the car to be locked and alarmed.
IMPORTANT
The car must be stationary when position
P is selected.
WARNING
Always apply the parking brake when park-
ing on a slope - the automatic transmis-
sion's P position is not sufficient to hold the
car in all situation.
Reverse position - RThe car must be stationary when R position is
selected.
Neutral position - NNo gear is engaged and the engine can be
started. Apply the parking brake if the car is
stationary with the gear selector in N position.
Drive position - DD is the normal driving position. Shifting up and
down takes place automatically based on the
level of acceleration and speed. The car must
be stationary when the gear selector is moved
to D position from R position.

Geartronic – Manual gear positions (+/-)The driver can also change gear manually
using the Geartronic automatic gearbox. The
car engine-brakes when the accelerator pedal
is released.
Manual gearshift mode is obtained by moving
the lever to the side from D position to the end
position at +/–. The information display shifts
the indication from
D to one of the figures 1 –6, which is equivalent to the gear that is
engaged just then, see page 71.
•Move the lever forwards towards + (plus)
to change up a gear and release the lever,
which returns to its rest position between
+ and –.
or
•Pull the lever back towards – (minus) to
change down a gear and release it.
The manual gearshift mode (+/–) can be
selected at any time while driving.
Geartronic automatically shifts down if the
driver allows the speed to decrease lower than
a level suitable for the selected gear, in order
to avoid jerking and stalling.
To return to automatic driving mode:
•Move the lever to the side to the end posi-
tion at D.
NOTE
f the gearbox has a Sport programme then
the gearbox will only become manual after
the lever has been moved forwards or back-
wards in its (-+/–) position. The information
display then shifts the indication from
S to
show which of the gears 1-6 is engaged.
Geartronic - Sport mode (S)2
The Sport programme provides sportier cha-
racteristics and allows higher engine speed for
the gears. At the same time it responds more
quickly to acceleration. During active driving,
the use of a lower gear is prioritised, leading to
a delayed upshift.
Sport mode is obtained by moving the lever to
the side from D position to the end position at
+/–. The information display shifts the indica-
tion from
D to S.
Sport mode can be selected at any time while
driving.
Geartronic - Winter modeIt can be easier to pull away on slippery roads
if 3rd gear is engaged manually.
1. Depress the brake pedal and move the
gear lever from D position to the end posi-tion at +/– - the instrument panel display
shifts the indication from
D to the figure 1.
2. Scroll up to gear 3 by pushing the lever
forward towards + (plus) twice - the display
shifts the indication from
1 to 3.
3. Release the brake and accelerate carefully.
The gearbox "winter mode" means that the car
moves off with a lower engine speed and
reduced engine power on the drive wheels.
Kick-downWhen the accelerator pedal is pressed all the
way to the floor (beyond the position normally
regarded as full acceleration) a lower gear is
immediately engaged. This is known as kick-
down.
If the accelerator is released from the kick-
down position, the gearbox automatically
changes up.
Kick-down is used when maximum accelera-
tion is needed, such as for overtaking.
Safety functionTo prevent overrevving the engine, the gearbox
control program has a protective downshift
inhibitor which prevents the kick-down func-
tion.
2Only models D5 and T6.

Geartronic does not permit downshifting/kick-
down which would result in an engine speed
high enough to damage the engine. Nothing
happens if the driver still tries to shift down in
this way at high engine speed – the original
gear remains engaged.
When kick-down is activated the car can
change one or more gears at a time depending
on engine speed. The car changes up when the
engine reaches its maximum speed in order to
prevent damage to the engine.
Mechanical gear selector inhibitor
G021351
The gear selector can be moved forward and
back freely between N and D. Other positions
are locked with a latch that is released with the
inhibitor button on the gear selector.With the inhibitor button depressed the lever
can be moved forwards or backwards between
P, R, N and D.
Automatic gear selector inhibitorThe automatic gearbox has special safety sys-
tems:
Parking position (P)Stationary car with engine running:
Keep your foot on the brake pedal when mov-
ing the gear selector to another position.
Electric gear inhibitor – Shiftlock Parking
position (P)
To be able to move the gear selector from P to
other gear positions, the brake pedal must be
depressed and the remote control key must be
in position II, see page 78.
Shiftlock – Neutral (N)If the gear selector is in N position and the car
has been stationary for at least 3 seconds (irre-
spective of whether the engine is running) then
the gear selector is locked.
To be able to move the gear selector from N to
other gear positions, the brake pedal must be
depressed and the remote control key must be
in position II, see page 78.
Deactivate automatic gear selector
inhibitor
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 open the
hatch.
Fully insert the key blade. Press the key
blade down and hold (For information on
the key blade, see page 48.)
Move the gear selector from the P position.

* Option/accessory, for more information, see Introduction.125 Automatic gearbox Powershift*
D: Automatic gear positions. +/–: Manual gear
positions.
Powershift is a 6-stage automatic gearbox that
has double mechanical clutch discs in contrast
to a conventional automatic gearbox. A con-
ventional automatic gearbox has a hydraulic
torque converter instead that transfers power
from engine to gearbox.
Powershift transmission operates in the same
way and has similar controls and functions as
the Geartronic automatic transmission, 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 transmis-sion, this can be verified by checking the des-
ignation on the transmission's label under the
bonnet - see page 370. The designa-
tion ”MPS6” means that it is Powershift – trans-
mission otherwise it is Geartronic automatic
transmission.
HSAThe HSA (Hill Start Assist) function means that
the pressure in the brake system remains for
several seconds while the foot is moved from
the brake pedal to the accelerator pedal before
setting off or reversing uphill.
The temporary braking effect releases after
several seconds or when the driver acceler-
ates.
To bear in mindThe 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 illu-
minates and the information display shows a
message. The transmission can also overheat
during slow driving in queues (10 km/h orslower) on an uphill gradient, 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 forward a short distance, and then
wait another moment with your foot on the
brake pedal.
IMPORTANT
Use the foot brake to hold the car stationary
on an uphill gradient - do not hold the car
with the accelerator pedal. The gearbox
could then overheat.
For important information regarding Powershift
transmission and towing - see page 304.
Text message and actionIn some situations the display may show a
message at the same time as a symbol is illu-
minated.

The table shows three steps with an increased
degree of seriousness should the transmission
become too hot. In parallel with the display text
the driver is also advised that the car's elec-
tronics are temporarily changing the driving
characteristics. Follow the instructions on the
information display where appropriate.
NOTE
The table's examples are no indication that
the car is defective but instead show that a
safety function has been activated inten-
tionally to prevent damage to one of the
car's components.
WARNING
If a warning symbol combined with the textTransm. overheat park safely is ignored
then the heat in the gearbox may become
so high that the power transmission
between engine and gearbox is temporarily
halted in order to prevent the clutch from
malfunctioning - the car then loses drive and
is stationary until gearbox temperature has
cooled to an acceptable level.
