Sitting safely
The ideal sitting position can make a vital con-
tribution to relaxed, fatigue-free driving. In the
interaction with the safety belts, the head
restraints and the airbags, the seat position
plays an important role in an accident. To
ensure that the safety systems operate with
optimal efficiency, we strongly urge you to
observe the instructions contained in the fol-
lowing section.
For additional information on transporting chil-
dren safely, refer to page52.
Airbags
Always maintain an adequate distance
between yourself and the airbags. Always
hold the steering wheel by its rim with hands at
the 9 o'clock and 3 o'clock positions, to mini-
mize the risk of injuries to your hands and arms
in the event of airbag deployment.
No one and nothing is to come between the air-
bags and the seat occupant.
Do not use the cover of the front airbag on the
front passenger side as a storage area. Make
sure that the front passenger is sitting correctly
and does not rest feet or legs on the instrument
panel, otherwise leg injuries can occur if the
front airbag is triggered.
Make sure that occupants do not rest their head
on the side or head airbag, otherwise injuries
can occur if the airbags are triggered.<
Even if you adhere to all the instructions, inju-
ries resulting from contact with airbags cannot
be fully excluded, depending on the circum-
stances. The ignition and inflation noise may
provoke a mild hearing loss in extremely sensi-
tive individuals. This effect is usually only tem-
porary.
For airbag locations and additional information
on airbags, refer to page90.
Head restraints
A correctly adjusted head restraint reduces the
risk of spinal injury in the event of an accident.
Adjust the head restraint so that its center
is approx. at ear level. Otherwise there is
increased danger of injury in the event of an
accident.<
Safety belts
Before every drive, make sure that safety belts
are being worn at all of the occupied seats. Air-
bags complement the safety belt as an addi-
tional safety device, but they do not represent a
substitute.
Your vehicle is provided with five seats, which
are all equipped with a safety belt.
Never allow more than one person to
wear a single safety belt. Never allow
infants or small children to ride in a passenger's
lap. Pregnant women should also always wear a
safety belt and make sure that the belt rests low
on the hips in the lap area, and does not press
against the abdomen. Do not route the belt
across your neck, or run it across sharp edges.
Be sure that the belt does not become caught
or jammed. Make sure that the safety belt is
securely fastened across the lap and shoulders,
as close to the body as possible without it being
twisted or tangled. Be sure not to route it over
solid or breakable objects, otherwise the belt
can slip over the hips in the lap area in a frontal
impact and injure the abdomen. Avoid wearing
clothing that prevents the belt from fitting prop-
erly and pull the belt in the upper body area peri-
odically to readjust the tension, in order to avoid
a reduction in the restraint of the safety belt.
Sports Wagon: if the middle safety belt in the
rear is used, the larger seatback half must be
locked, refer to page111, otherwise the middle
safety belt has no restraining action.<
For instructions on operating safety belts, refer
to page47.

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.

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

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.
