Active seat ventilation*
The system progresses one step through the
control sequence each time you press the but-
ton.
To switch off: press the button longer.
The highest position with three LEDs is
used for rapid cooling, e.g. when the vehi-
cle has gotten heated up. After a short time, the
system is automatically switched down one
position in order to prevent excessive cooling.<
Active seat*
The seat cushion is actively varied by alter-
nately raising and lowering the right and left half
of the seat cushion. This reduces muscular ten-
sion and fatigue to help prevent lower back
pain.
Press the button to switch on; the LED lights
up.
If you switch off the active seat, it can take up to
1 minute before the two halves of the seat
cushion have returned to their initial position.
Mirrors
Exterior mirrors
The mirror on the passenger's side is
more curved than the driver's mirror.
Objects reflected in the mirror are closer than
they appear. Do not estimate the distance of
following traffic based what you see in the mir-
rors, otherwise there is an increased accident
risk.<

2Switching to the other mirror or to the auto-
matic parking function, refer to Tilting down
passenger-side exterior mirror on page50
Storing the mirror positions, refer to Seat, mir-
ror and steering wheel memory on page45.
Manual adjustment
You can also adjust the mirrors manually by
pressing against the outer edges of their mirror
glass.
Folding mirrors in and out
To prevent the exterior mirrors on this
vehicle from being damaged, always fold
them in by hand before entering an automatic
car wash.<

Starting engine
Do not run the engine in closed rooms,
otherwise the inhaling of toxic exhaust
gases can cause unconsciousness and death.
The exhaust gases contain carbon monoxide,
an odorless and colorless, but highly toxic gas.
Never leave an unattended vehicle with the
engine running, as such a vehicle represents a
potential safety hazard.
Before leaving the vehicle with the engine run-
ning, set the selector lever to the idling or the
P position and set the handbrake, otherwise the
vehicle can begin to roll.<
When starting the engine, do not press the
accelerator pedal.
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, begin to drive immediately at a moder-
ate engine speed.
Manual transmission
1.Apply the handbrake.
2.Depress the clutch pedal and select the
idling position.
3.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
Automatic transmission with
Steptronic*
1.Depress brake pedal.
2.Briefly press the Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-ically disengaging it as soon as the engine
starts.
SMG Sequential Manual Gearbox*
1.Depress brake pedal.
2.Engage the selector lever position N and
make sure that this position is also indi-
cated in the instrument cluster.
3.Briefly press Start/Stop button.
The system responds by automatically engag-
ing the starter for a certain period and automat-
ically disengaging it as soon as the engine
starts.
If the engine fails to start, depress the
brake pedal and press the selector lever
to the right then engage the position N. Watch
the display in the instrument cluster while doing
so.<
Special starting conditions
Depress the accelerator pedal half way when
starting the engine in the following situations:
>The engine fails to start on the first attempt,
e.g. if it is very hot or cold.
>The engine is started at very low tempera-
tures, below approx. + 57/– 156, at high
altitudes, over approx. 3,300 ft/1,000 m.
Avoid frequent starting in quick succes-
sion or repeated start attempts in which
the engine does not start. Otherwise, the fuel is
not burned or inadequately burned and there is
a danger of overheating and damaging the cat-
alytic converter.<
Switching off engine
Do not remove the remote control from
the ignition lock while the vehicle is roll-
ing, otherwise the steering wheel lock would
engage while steering.
When leaving the vehicle, always take the
remote control with you. When parking on a
downhill slope, apply the handbrake, otherwise
the vehicle could roll.<

SMG Sequential Manual
Gearbox*
The concept
The SMG Sequential Manual Gearbox is an
automated manual transmission in which an
electrohydraulic system handles the clutching
and gear changes.
You operate SMG with the selector lever in the
center console and two shift paddles on the
steering wheel.
It offers you the following functions:
>Optional manual or automatic operation:
Sequential mode or Drive mode
>You have a choice of two driving programs:
Normal or Sport, refer to Dynamic Driving
Control page60
>Automatic downshifting and prevention of
incorrect shifting even in sequential opera-
tion
>Acceleration assistant, refer to page61.
Selector lever positions
The current selector lever position is displayed
on the center console.
>R: Reverse gear
>N: Neutral>One-touch functions for Sequential mode:
+: manual upshifting
–: manual downshifting
>D: activate/deactivate the Drive mode
The transmission automatically shifts
into N if the driver's door is opened with
the engine running and neither the pedals, the
shift paddles nor the selector lever are oper-
ated.
This is indicated by an acoustic signal and the
flashing display N in the instrument cluster.<
Gear display
R N 1 to 6
The currently engaged gear is displayed, pre-
ceded by a D in Drive mode.
It is only possible to recognize whether
the desired selector lever position is
engaged with this display.<
Shiftlock
Press the brake pedal before shifting out of N;
the shift command will not be executed unless
the brake is applied.
R Reverse
Select only when the vehicle is stationary.
Sequential mode
After every engine start, as soon as the selector
lever is pushed to the right and the brake pedal
is pressed, the Sequential mode is activated.
You can shift up and down using the shifting
paddles or the selector lever. You do not need
to remove your foot from the accelerator to do
so.

Steptronic*
In addition to fully automatic operation, you can
also manually shift with the Steptronic, refer to
page62.
