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, move the selector lever into the N 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.
Do not press the brake pedal as long as
you do not want to start the engine. The
engine starts immediately when you briefly
press the Start/Stop button with the brake
pedal depressed.<
1.Depress brake pedal.
2.Place selector lever in position N.
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 does not start, shift back to
the last selector lever position selected,
refer to the instrument cluster display or the
selector lever. Then select the position N.
You cannot start off with the hood open.
When the engine is cold, the exhaust system
has a slightly metallic undertone due to the sys-
tem design.<
Avoid frequent starting in quick succes-
sion or repeated starting 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 catalytic converter.<
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.
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 incline, apply the
handbrake, as otherwise the vehicle could roll
away.<
1.Apply the handbrake.
2.Engage a driving position.
3.Briefly press the Start/Stop button.
A signal sounds when the position N is
engaged and the handbrake is not set when
switching off the engine.
Driving
56
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 result 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.

reached, the entire tachometer beings to flash.
When the maximum rpm is exceeded, the fuel
supply is cut off to protect the engine. Always
avoid engine speeds in this range.
M Engine Dynamic Control
With M Engine Dynamic Control you can influ-
ence how sporty the reaction of your vehicle to
accelerator pedal movements is to be. Three
programs are available for engine control.
"P 400" program
In the "P 400" program the engine reacts gently
to the movement of the accelerator pedal. This
is, for example, ideal for city driving or driving on
snow. In the process, the fuel consumption is
minimal and the engine output is reduced.
"P 500" program
The "P 500" program provides maximum per-
formance and more spontaneous reaction of
the engine to accelerator pedal movements.
"P 500 Sport" program
In the "P 500 Sport" program the engine reacts
especially spontaneously and uncompromis-
ingly sporty with maximum performance to
accelerator pedal movements.
Selecting program
Each time the engine is started, the "P 400"
program is activated.
Press the POWER button to activate the
"P 500" program. Pressing the POWER button
repeatedly switches between the programs
"P 400" and "P 500".
You can also activate your preferred program
with the button on the steering wheel, refer
to MDrive on page48. You can only activate the
"P 500 Sport" program with MDrive.

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 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
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.<
Washer fluid reservoir
All washer jets are supplied from one reservoir.
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.<

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 road conditions
such as snow, rain, ice, and loose road surface.
Otherwise you could loose control of the vehi-
cle and cause an accident.<
