tion lock, refer to page55.
Parking brake
The parking brake is primarily intended to pre-
vent the vehicle from rolling while parked; it
brakes the rear wheels.
Indicator lamp
The indicator lamp lights up, and a sig-
nal sounds when you drive away. The
parking brake 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 parking
brake while the vehicle is in motion, do not pull it
too firmly. In doing so, continuously press the
button of the parking brake lever. Otherwise,
too firm an application of the parking brake 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 park-ing brake lightly when the vehicle is slowly com-
ing to a stop if the traffic conditions are suitable.
The brake lamps do not light up when the park-
ing brake is applied.<
Manual transmission*
While shifting in the 5th/6th gear lane,
press the gearshift lever toward the right,
otherwise accidental shifting into the 3rd or 4th
gear could result in engine damage.<
When shifting into 1st gear, you may feel a
slight jolt. This part of normal operation and no
reason for concern.
Reverse gear
Select only when the vehicle is stationary.
When pressing the gearshift lever to the left,
overcome some resistance.
Shift lights
To achieve the best vehicle acceleration with a
sporty driving style, shift lights in the Head-up

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 you the following functions:
>Optional manual or automatic operation:
Sequential mode or Drive mode
>Selection option between different driving
programs, Drivelogic, refer to page59
>Upshift display, shift lights, refer to page60
>Automatic downshifting and prevention of
incorrect shifting even in Sequential opera-
tion
>Automatic double clutching
Selector lever positions
>R: Reverse gear
>N: Neutral
>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 select 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 manually shift into idling mode.
The system shifts into N when you open
the driver's door or the hood with the
engine running and do not operate pedals, shift
paddles or the selector lever. To begin driving
after closing the driver's door or the hood, first
shift the selector lever into the N position, and
then shift into drive.<
S Sequential mode
You can shift up and down using the shift pad-
dles or the selector lever. You do not need to
remove your foot from the accelerator to do so.
Shifting from Sequential mode to Drive mode:
press selector lever to the right toward D/S.
To switch back into the Sequential mode: shift
using the shift paddles or the selector lever or
press selector lever to the right toward D/S
again.
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 result in a feasible combina-
tion of engine and vehicle speed; thus, for
example, a downshift that would cause the
engine to overrev will not be executed by
the system.
>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:
shift using the shift paddles or the selector
lever, or press the selector level to the right in
the D/S direction.
Shifting back to Drive mode: press the selector
lever to the right in the D/S direction again.
Kickdown: for rapid acceleration, e. g. when
passing, press the accelerator pedal as far
down as it will go. You achieve maximum accel-
eration.

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
There are five different driving programs, rang-
ing from relaxed 1 to sporty/highly dynamic 5.
In Sequential mode
You can choose from six driving programs from
balanced/dynamic 1 to sporty/purist 6.
Program 6 is only available when the DSC
Dynamic Stability Control is deactivated, refer
to page76. If DSC is activated, then the system
switches from program 6 to program 5.
To maintain vehicle stability, always acti-
vate DSC whenever possible.<

the washer fluid reservoir is empty, otherwise
you will damage the washer pump.<
Windshield washer nozzles
The windshield washer nozzles are heated
when the engine is running or the ignition is
switched on.
Washer fluid
Washer fluid antifreeze is flammable. For
this reason, keep it away from ignition
sources and store only in the closed original
container out of reach of children. Otherwise,
there is the danger of bodily injury. Always
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
All washer nozzles are supplied from one reser-
voir.

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. If the engine braking effect is insufficient
on a downhill grade, the set speed may be
exceeded. Speed can drop on uphill grades if
the engine output is insufficient.
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 road conditions
such as snow, rain, ice, loose road surface, and
poor visibility. Otherwise you could lose control
of the vehicle and cause an accident.<
