System limitations
This transmission is equipped with an over-
heating protection system that protects the
clutches against extremely high loads.
The indicator lamp lights up yellow if
the transmission becomes too warm.
Avoid high engine loads and driving off
frequently.
If the transmission overheats, the indicator
lamp lights up red and power flow to the engine
is interrupted. You can only continue driving
after the transmission has cooled down.
Avoid driving off frequently with high accelera-
tion and do not hold the vehicle on inclines by
depressing the accelerator lightly; otherwise,
the transmission may overheat.

>Transmission position P can only be disen-
gaged if the engine is running.
>Before moving the lever away from P or N
with the vehicle stationary, depress the
brake; otherwise, the transmission will not
shift.Briefly push the selector lever in the desired
direction, beyond a resistance point if nec-
essary.
When shifting out of P or into R, press button1
at the same time.
The engaged transmission position is also dis-
played on the selector lever.
When you release the selector lever, it returns
to its center position.
N Neutral
The vehicle can roll.
N remains engaged after the engine is
switched off if the remote control remains
in the ignition lock. This function can be used in
an automatic car wash, for example. P is auto-
matically engaged after approx. 30 minutes.<
D drive mode
In drive mode, all forward gears are shifted auto-
matically.
R Reverse
Select this only when the vehicle is stationary.
Engaging transmission position P
Select this only when the vehicle is stationary.

P Park
The rear wheels are locked.
P is engaged automatically when the following
conditions are met:
>The driver's door is opened while the
engine is running, your safety belt is not fas-
tened and neither the brake pedal nor the
accelerator are activated.
>The engine is switched off unless N is
engaged and the remote control is in the
ignition lock.
>The remote control is removed from the
ignition lock.
Kickdown
T o a cc ele ra te ra pidly, e.g., when passing, press
the accelerator down past the resistance point.
This provides maximum acceleration.
Activating the Sport program and
manual mode M/S
Move the selector lever from position D toward
the left:
The Sport program is activated.
Sport program
S1 through S7 is displayed in the instrument
cluster. This position is recommended for a
performance-oriented driving style.
Manual mode:
When you press the selector lever forward or
backward, or when you press the shift paddles,
manual mode is activated and the gear is
changed.
M1 through M7 are displayed in the instrument
cluster.The transmission provides assistance in the fol-
lowing situations:
>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 stops, the transmission
automatically shifts down to first gear.
>Shortly before the vehicle slows down to
below the minimum speed of the gear cur-
rently engaged, the transmission automati-
cally shifts down without requiring your
intervention.
Rapid downshifting: in manual mode, you can
skip several gears to achieve optimal accelera-
tion. Do so by pressing the accelerator past the
resistance point.
Changing to drive mode
Push the selector lever to the right.
Shifting gears via the selector lever
In manual mode:
>To shift up, pull back the selector lever.
>To shift down, push it forward.
Shifting gears via the shift paddles on
the steering wheel
The shift paddles allow you to shift gears with-
out taking your hands off the steering wheel.
You do not need to raise your foot from the
accelerator when doing so.
>To shift up: press one of the shift paddles
back, arrow1.

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 on 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.
Accelerating using the lever
Accelerating slightly:
Press the lever to the resistance point, arrow 1,
and hold until the desired speed is reached.Accelerating significantly:
Press the lever beyond the resistance point,
arrow 1, and hold until the desired speed is
reached.
The vehicle accelerates without pressure on
the accelerator pedal. The system stores and
maintains the speed.
Decreasing speed
Repeatedly pull the lever to the resistance point
or beyond, arrow 2, until the desired speed is
displayed.
>Each time the lever is pulled to the resis-
tance point, the desired speed is decreased
by approx. 1 mph or 1 km/h.
>Each time the lever is pulled beyond the
resistance point, the desired speed is
reduc ed by up to 5 mph o r 10 km/h until the
minimum speed of 20 mph or 30 km/h is
achieved.
The system stores and maintains the speed.
Interrupting the system
Tap the lever upwards or downwards, arrow3.
The displays in the speedometer change color.
In addition, the system is automatically deacti-
vated:
>When you brake the vehicle
>When you switch gears very slowly or shift
to neutral in cars with a manual trans-
mission
>When you engage selector lever position N
in cars with an automatic transmission
>When you engage transmission position N
in 7-gear sport automatic transmissions
with a dual clutch
>When you activate the DTC Dynamic Trac-
tion Control or deactivate DSC
>When DSC or ABS is intervening
Cruise control is not deactivated by depressing
the accelerator pedal. Once the accelerator
pedal is released, the stored speed is achieved
again and maintained.

warning lamp lights up. There is an increased
risk of black ice.Black ice can also form at temperatures
above +377/+36. You should there-
fore drive carefully on bridges and shaded
roads, for example; otherwise, there is an
increased risk of an accident.<

Coolant temperature
A warning lamp will come on if the coolant, and
therefore the engine, becomes too hot. In addi-
tion, a message will appear on the Control
Display.
Check coolant level, refer to page204.
Engine oil temperature*
When the engine is at normal operating
temperature, the engine oil temperature is
between approx. 2107/1006 and approx.
3007/1506.
If the engine oil temperature is too high, a mes-
sage appears on the Control Display.
Fuel gauge
Fuel tank capacity: approx. 14.5 US gallons/
55 liters.
You can find information on refueling
on page192.
If the tilt of the vehicle varies for a longer period,
when you are driving in mountainous areas, for
example, the indicator may fluctuate slightly.
Reserve
Once the fuel level has fallen to the reserve
zone, a message briefly appears on the Control
Display and the cruising range for the remaining
amount of fuel is displayed on the computer.
Under a cruising range of approx. 30 miles/
50 km, the message remains in the Control
Display.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<

with the remaining fuel. The range is calculated
on the basis of the way the car has been driven
over the last 18 miles/30 km and the amount of
fuel currently in the tank.
Refuel as soon as possible once your
cruising range falls below 30 miles/
50 km; otherwise, engine functions are not
ensured and damage can occur.<
Average speed
Periods with the vehicle parked and the engine
switched off are not included in the calculations
of average speed.
With the trip computer, refer to page67, you
can have the average speed for another trip
displayed.
To reset average speed: press the button in the
turn indicator lever for approx. 2 seconds.
Average fuel consumption
The average fuel consumption is calculated for
the time during which the engine is running.
With the trip computer, refer to page67, you
can have the average consumption for another
trip displayed.
To reset average fuel consumption: press the
button in the turn indicator lever for approx.
2seconds.
Current fuel consumption
Displays the current fuel consumption. This
allows you to see whether your current driving
style is conducive to fuel economy with mini-
mum exhaust emissions.
