eral support is automatically adapted to the cur-
rent driving situation.
The adaptation of the backrest width and the

grams from comfort to sport. The "Sport" pro-
gram provides increased lateral support on both
sides when driving through a quick succession
of curves.
Press the button repeatedly until the desired
program is shown on the Control Display. The
LED in the button lights up.
To switch off: press button longer.
You can also activate your preferred program
for the active backrest width adjustment of the
driver's seat with the button on the steering
wheel, refer to MDrive on page50.
Easy entry/exit*

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 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 position N and then into
the drive position.<
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.
After every engine start, as soon as the selector
lever is pushed to the right into the drive posi-
tionΒ 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, 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:
press selector lever to the right toward D/S.
To switch back into the Sequential mode: press
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. when
passing, press the accelerator pedal as far
down as it will go. You achieve maximum accel-
eration.

Activating rain sensor
Press the button, arrow3. The LED in the but-
ton lights up.
Adjusting rain sensor sensitivity level
Turn the knurled wheel5.
Deactivating rain sensor
Press the button again, arrow3. The LED goes
out.
Deactivate the rain sensor when passing
through an automatic car wash. Failure to
do so could result in damage caused by undes-
ired wiper activation.<
Cleaning windshield and headlamps
Pull the lever, arrow4.
The system sprays washer fluid against the
windshield and activates the wipers for a brief
period.
When the vehicle lighting is switched on, the
headlamps are simultaneously washed at
appropriate intervals.
Do not use the washing mechanisms 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 washing mechanisms when
the washer fluid reservoir is empty, otherwise
you 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
observe the instructions for use provided on the
containers.<
Filler neck for washer fluid
Only add washer fluid with the engine
cooled down to exclude contact with hot
engine components. Otherwise there is a dan-
ger of fire and to personal safety if the fluid is
spilled.<
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
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. To maintain the specified speed, the sys-
tem brakes if the engine braking effect is not
sufficient on a downhill grade. Speed can drop
