Starting the 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, otherwise such a vehicle repre-
sents a potential safety hazard.
Before leaving the car with the engine running,
place the transmission in idle or move the
selector lever to position P and apply the hand-
brake to prevent the car from moving.<
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 depress either the brake or the
clutch until you are ready to start the
engine. The engine is started immediately
when you briefly touch the start/stop button
and depress the brake if the car has automatic
transmission, or the clutch if the car has manual
transmission.<
Manual transmission
1.Apply the handbrake.
2.Depress the clutch and shift to idle position.
3.Briefly press the start/stop button.
The starter operates automatically for a certain
time, and stops automatically as soon as the
engine has started.
Automatic transmission

attempt, for instance when it is extremely
hot or cold.
>If the engine is started at very low tempera-
tures, below approx. + 57/–156, at high
altitudes above 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 the engine
Always take the remote control with you
when you leave the vehicle.

Sequential manual gearbox
SMG*
The concept
The sequential manual gearbox SMG is an
automated transmission in which operation of
the clutch and gearshifts are performed by an
electro-hydraulic system.
SMG is operated via the selector lever in the
center console and two shift paddles on the
steering wheel.
It offers you the following functions:
>Choice of manual or automatic operation:
sequential mode or Drive mode
>Choice of two driving programs: Normal or
Sport, refer to Dynamic Driving Control,
page46
>Automatic downshifting and prevention of
misshifting in sequential mode as well
>Acceleration assistant, refer to page47
Selector lever positions
The current selector lever position can be seen
on the center console.
>R: Reverse gear
>N: Neutral, idle
>One-touch functions for sequential mode:
+: manual upshifting
–: manual downshifting>D: Drive mode or sequential mode
N is automatically selected when the
driver's door is opened while the engine is
running, as long as the pedals, shift paddles and
selector lever are not operated.
This is indicated by an acoustic signal and a
flashing N in the instrument cluster.<
Gear indicator
R N 1 to 6
The gear currently engaged is displayed, pre-
ceded by a D in Drive mode.
This indicator is the only way you can
confirm whether or not the desired selec-
tor lever position is engaged.<

Gear-change mode
The gears can be changed in two different
ways.
>Sequential mode
Gears are shifted by means of the shift pad-
dles or the selector lever.
>D Drive mode
All forward gears are shifted automatically.
You can switch from one mode to the other by
pressing the selector lever towards the right in
the direction of D.

the correct concentration is maintained.<
Capacity
Approx. 6.3 US quarts/6 liters.
Cruise control*
The concept
Cruise control is available for use at speeds of
approx. 20 mph or 30 km/h. The car then stores
and maintains the speed that you specify using
the lever on the steering column. In order to
maintain the specified speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving
conditions are unfavorable for driving at a
constant speed. Otherwise you could lose con-
trol of the vehicle and cause an accident as a
result. Unfavorable driving conditions include,
for example, winding roads, heavy traffic or a
poor road surface, e.g. snow, rain, ice or loose
material.<
Manual transmission/SMG
You can shift gears while cruise control is acti-
vated. An indicator lamp notifies you that you
should shift gears when you drive for an
extended period at very high or very low engine
speeds, or the system is deactivated.
In Drive mode, the SMG acts similarly to an
automatic transmission in position D.

Maintaining current speed
Tap the lever, arrow 1, or pull it briefly, arrow 2.
The car's current speed is stored and main-
tained. It is displayed in the speedometer and
briefly in the instrument cluster.
On uphill gradients, it may prove impossible to
maintain the set speed if current engine power
output is insufficient. If the engine braking
effect is insufficient on downhill slopes, the sys-
tem will brake the vehicle slightly.
Increasing desired speed
Repeatedly press the lever to the resistance
point or beyond, arrow1, until the desired
speed is reached.
>Each time the lever is pressed to the resis-
tance point, the desired speed is increased
by approx. 1 mph or 1 km/h.
>Each time the lever is pressed beyond the
resistance point, the desired speed is
increased by up to 5 mph or 10 km/h.
The system stores and maintains the speed.
