Rearview mirror with compass.
The upper right-hand corner of the rearview
mirror has an integrated display that shows the
compass direction in which the front of the car
is pointing. Eight different directions are shown
with English abbreviations:
N (north), NE (north
east), E (east), SE (south east), S (south), SW(south west), W (west) and NW (north west).
The compass is activated automatically when
the car is started or in key position II, see
page 80. To deactivate/activate the compass -
press in the button on the underside of the mir-
ror using a paper clip for example.
CalibrationThe earth is divided into 15 magnetic zones.
The compass is set for the geographic area to
which the car was delivered. The compassshould be calibrated if the car is moved across
several magnetic zones.
1. Stop the car in a large open area free from
steel structures and high-voltage power
lines.
2. Start the car.
NOTE
For optimum calibration - switch off all elec-
trical equipment (climate control system,
wipers etc.) and make sure that all doors are
closed.
3. Hold the button on the underside of the
rearview mirror depressed
approx. 6 seconds (using a paper clip for
example) until the character
C is shown.

Jump starting
If the battery is flat then the car can be started
with current from another battery.
When jump starting the car, the following steps
are recommended to avoid short circuits or
other damage:
1. Insert the remote control key in key posi-
tion 0, see page 80.
2. Check that the donor battery has a voltage
of 12 V.
3. If the donor battery is installed in another
car - switch off the donor car's engine and
make sure that the two cars do not touch
each other.4. Connect one of the red jump lead's clamps
to the donor battery's positive terminal (1).
IMPORTANT
Connect the start cable carefully to avoid
short circuits with other components in the
engine compartment.
5. Open the clips on the front cover of the
battery in your car and remove the cover,
see page 328.
6. Connect the red jump lead's other clamp
onto the car's positive terminal (2).
7. Connect one of the black jump lead's
clamps to the donor battery's negative ter-
minal (3).
8. Connect the other clamp to a grounding
point, e.g. right-hand engine mounting at
the top, the outer screw head (4).
9. Check that the jump lead clamps are
affixed securely so that there are no sparks
during the starting procedure.
10. Start the engine of the "donor car" and
allow it to run a few minutes at a speed
slightly higher than idle approx. 1500 rpm.
11. Start the engine in the car with the dis-
charged battery.
IMPORTANT
Do not touch the crocodile clips during the
start procedure. There is a risk of sparks
forming.
12. Remove the jump leads in reverse order -
first the black and then the red.
> Make sure that none of the black jump
lead's clamps comes into contact with
the battery's positive terminal or the
clamp connected to the red jump lead!
WARNING
•The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.
•The battery contains sulphuric acid,
which can cause serious burns.
•If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.
For more information on the car's battery - see
page 327.

play shifts the indication from D to the fig-
ure 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.
Geartronic does not permit downshifting/kick-
down which would result in an engine speed
high enough to damage the engine. Nothinghappens 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 80.
Shiftlock – Neutral (N)If the gear selector is in the N position and the
car has been stationary for at least 3 seconds
(irrespective 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 80.

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 50.)
Move the gear selector from the P position.
Automatic gearbox Powershift*
D: Automatic gear positions. M (+/–): Manual gear
positions.
Powershift is a six-stage automatic gearbox
that has double mechanical clutch discs in
contrast to a conventional automatic gearbox.
A conventional automatic gearbox has a
hydraulic torque converter instead that trans-
fers 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 decal number (5) under thebonnet - see page 352. 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 or
slower) 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.
