Starting engine
Do not run the engine in closed rooms,
otherwise the inhalation 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, shift into neutral
* or move the selector
lever into position N and firmly apply the hand-
brake, otherwise the vehicle can begin to roll.<
Do not allow the engine to warm up by leaving it
running while the vehicle remains stationary.
Instead, drive off at a moderate engine speed.
Avoid frequent starting in quick succes-
sion or repeated starting attempts in
which the engine does not start. Otherwise, the
fuel is not burned at all or is burned inade-
quately and there is a danger of overheating and
damage to the catalytic converter.<

Handbrake
The handbrake is primarily intended to prevent
the vehicle from rolling while parked; it brakes
the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal also sounds when starting off. The
handbrake is applied.
Indicator lamp for Canadian models.
Applying
The lever locks in position automatically.
Releasing
Pull slightly upwards, press the button and
lower the lever.
If exceptional circumstances should
make it necessary to apply the handbrake
while the vehicle is in motion, do not pull it too
firmly. In doing so, continuously press the but-
ton of the handbrake lever. Otherwise, too firm
an application of the handbrake can lock up the
rear wheels and cause the rear of the vehicle to
swerve.<
To prevent corrosion and one-sided brak-
ing action, occasionally engage the hand-
brake lightly when the vehicle is slowly coming
to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the hand-
brake is applied.<
Manual transmission*
When shifting into 5th/6th gear, press the
gearshift lever toward the right, otherwise
an inadvertent shift into 3rd or 4th gear could
lead to engine damage.<
When engaging the 1st gear, a slight jolt may
occur. This is operation-related and no reason
for concern.
Reverse gear
Select only when the vehicle is stationary.
Press the gearshift lever to the left, overcoming
a slight resistance.
Shift lights
To achieve the best vehicle acceleration with a
sporty driving style, shift lights in the Head-Up
Display
* indicate the optimum shifting point
briefly before reaching the maximum rpm. Refer
to Shift lights, page63.

Sequential Manual
Transmission with Drivelogic
The concept
The SMG Sequential Manual Transmission
with Drivelogic is an automated manual trans-
mission in which an electrohydraulic system
handles the clutching and gear changes.
The Sequential Manual Transmission is oper-
ated with the selector lever and two shift pad-
dles on the steering wheel.
It offers the following functions:
>Choice of manual or automatic mode:
Sequential mode or Drive mode
>Selection option between different driving
programs, Drivelogic, refer to page62
>Upshift display, shift lights, refer to page63
>Automatic downshifting and prevention of
incorrect shifting even in sequential opera-
tion
>Automatic double clutching
Selector lever positions
>R: Reverse gear
>N: Neutral, idle
>Β: Drive position:
>+: manual upshifting
>–: manual downshifting
>D/S: switch between Drive mode and
Sequential mode
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.
N Idle
Always engage before starting engine.
If the driving situation requires, e.g. when down-
shifting on a slippery road surface, the Sequen-
tial Manual Transmission automatically
clutches and then declutches again, i.e. it is not
necessary to engage idling manually.
N is automatically engaged after just a
few seconds when you open the driver's
door or the hood with the engine running and do
not operate either pedals, shift paddles or the
selector lever. In these cases, to start off after
closing the driver's door or the hood, first move
the selector lever into the position N and then
into the drive position.<
S Sequential mode
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.
After every engine start, as soon as the selector
lever is pushed to the right into the drive posi-
tion Β and the brake pedal is pressed, the
Sequential mode is activated.
Starting off is also possible on a level road sur-
face in second gear, e.g. in case of ice.
In the following situations, the Sequential Man-
ual Transmission thinks for you:
>Upshifts and downshifts are executed only
when they will res ult in a plausible combina-
tion of engine and vehicle speed; thus, for
example, the system will not execute a
downshift that would cause the engine to
overrev.
>When the vehicle is stationary, the trans-
mission automatically downshifts into first
gear.
>Shortly before dropping below a gear-
dependent minimum speed, the transmis-
sion downshifts automatically even without
your intervention.

D Drive mode
In the Drive mode, all forward gears are shifted
automatically.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D/S.
To switch back into the Sequential mode: press
the selector lever to the right again toward D/S
or shift using the shift paddles or the selector
lever.
Kick-down: for rapid acceleration, e.g. passing,
press the accelerator pedal as far down as it will
go. You achieve maximum acceleration.

Drivelogic
With Drivelogic various driving programs are
available to you.
Each time you change between the Sequential
mode and the Drive mode, the driving program
last selected in the respective mode is active.
Exception: after the first change from the
Sequential to the Drive mode, driving program 3
is active.
In Drive mode
Five driving programs, from relaxed 1 to sporty/
highly dynamic 5 are available for selection.
In Sequential mode
You can choose from six driving programs from
balanced/dynamic 1 to sporty/purist 6.
Each time the engine is started, driving
program 3 is activated.
The sporty/purist driving program 6 is only
available with the DSC Dynamic Stability Con-
trol deactivated, refer to page82. When DSC
is activated, the system switches from driving
program 6 to 5.
To maintain vehicle stability, always drive
with the DSC switched on when possi-
ble.<

66 Do not use the washers if there is any
danger that the fluid will freeze on the
windshield. If you do so, your vision could be
obscured. To avoid freezing, use a washer fluid
antifreeze, refer to Washer fluid. Do not use
washers when the washer fluid reservoir is
empty, as this will damage the washer pump.<
Windshield washer nozzles
Both windshield washer nozzles are automati-
cally heated with the engine running or the igni-
tion switched on.
Washer fluid
Washer fluid antifreeze is flammable.
Always keep it well away from sparks and
open flames, and store it in tightly closed con-
tainers well out of the reach of children. Always
follow the instructions for use provided on the
containers.<
Filler neck for washer fluid
All washer nozzles are supplied from one reser-
voir.
Fill with water and – if required – with a washer
antifreeze, according to manufacturer's recom-
mendations.
In order to maintain the mixture ratio, mix the
washer fluid before filling.<
Capacity
Capacity approx. 5.3 US quarts/5 liters.
Cruise control
The concept
The cruise control is available for use at speeds
of approx. 20 mph/30 km/h and higher. The
vehicle stores and maintains the speed that you
set using the lever mounted on the steering col-
umn.
Do not use the cruise control under driv-
ing conditions that do not permit a con-
stant speed, e.g. when driving on winding
roads , in heavy traffic or in poor roa d co nditions
such as snow, rain, ice, and loose road surface.
Otherwise, you could lose control of the vehicle
and cause an accident.<
