ControlsDriving
Upshifts and downshifts are executed only
when they will result in a plausible combination
of engine and vehicle speed; thus, for example,
a downshift that would cause the engine to
overrev will not be exec uted by the system.
The gear selected is briefly displayed in the
instrument cluster, followed again by the gear
actually in use.
Overriding selector lever lock
Should the selector lever refuse to move out of
position P even though the ignition is switched
on, the brake is depressed and the button on
the selector lever is pre ssed, the selector lever
lock can be overridden:
1. Switch off ignition.
2. Unclip the sleeve of the selector lever.
3. Pull the sleeve up over the selector lever
until the sleeve is inside out.
4. Using the screwdriver from the onboard
vehicle tool kit, refer to page 270, press the
red lever and with the button pressed,
simultaneously move th e selector lever to
the desired position.
7-gear Spor t automatic
transmission with double
clutch
The concept
The 7-gear Sport automa tic transmission with
double clutch is an automated manual trans-
mission with two clutches and secondary gear sets in which the clutch
ing and shifting is han-
dled by an electrohydraulic system.
With the 7-gear Sport automatic transmission
with double clutch, the gears are shifted without
an interruption in driving power.
You operate the 7-gear Sport automatic trans-
mission with double clutch using the selector
lever and two shift paddles on the steering
wheel.
It offers you the following functions:
> Either manual or au tomatic mode: sequen-
tial mode or drive mode
> Automatic downshifting and protection
against incorrect gear selection, even in
sequential mode
> Acceleration assistan t, Launch Control,
refer to page 70
> Automatic intermediate throttle application
System limitations
The 7-gear Sport automatic transmission with
double clutch has an overheating protection
that protects the clutch from extreme loads.
The indicator lamp lights up in yellow if
the transmission becomes too warm.
Avoid high engine loads and frequent
accelerations from zero. If the transmission is
overheated, the indicator lamp lights up in red
and the power flow to the motor is interrupted. It
is only possible to continue driving once the
transmission has cooled down.
Avoid frequent powerful accelerations from
zero and do not hold the vehicle on inclines by
pressing lightly on the accelerator while letting
the clutch slip, as this may cause the transmis-
sion to overheat.

Engaging selector lever positions
>
The selector lever can be moved out of
position P only with the engine running:
interlock.
> Before moving the lever away from P or N
with the vehicle statio nary, first depress the
brake; otherwise, the desired shift will not
be executed: shiftlock.
Shifting into N, D, R
Briefly push the selector lever in the desired
direction, overcoming a resistance point if nec-
essary. When shifting out of P or into R, simul-
taneously press the button 1 .
The engaged selector lever position is also dis-
played on the selector lever.
When you release the sele ctor lever, it returns
to its center position.
Shifting into P
Press the button P.
P Park
Select this only when the vehicle is stationary.
The rear wheels are locked.
The transmission is shifted into P if, with
the engine running, you open the driver's
doo r, do not have yo ur sa fety belt fastened, and
subsequently actuate neither the brake pedal
nor the accelerator. Befo re leaving the vehicle,
make sure that the au tomatic transmission
selector lever is in the park position. Otherwise,
the vehicle may begin to move. <
The transmission is shifted into P as soon
as you switch off th e engine, unless the
transmission is in N and the remote control is in
the ignition lock, refer to page 267. As soon as
you remove the remote control from the ignition
lock, then the transmission is shifted into P. <
R Reverse
Select this only when the vehicle is stationary.
N Neutral
You can select this in a car wash, for example.
The vehicle can roll.
After the engine is switched off, the trans-
mission remains in N if you leave the
remote control in the ignition lock. You can use
this function at a car wash, for example, refer to
page 267.<

D Drive mode
In Drive mode, all forward gears are shifted
automatically.
Kickdown
For sudden acceleration maneuvers such as
passing, depress the accelerator past the resis-
tance point. This prov ides maximum accelera-
tion.
Sport program and
manual mode M/S
Push selector lever towa rd the left from the
selector lever position D, the Sport program is
activated. This position is recommended for a
performance-oriented driving style.
The engaged gear, e.g. S1, is displayed in the
instrument cluster.
When you press the selector lever forwards or
backwards, the manual mode is activated and
Steptronic changes gear.
The engaged gear, e.g. M1 is displayed in the
instrument cluster.
In the following situat ions, the 7-gear Sport
automatic transmission with double clutch
does the thinking 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 could cause the
engine to overrev will not be executed by
the system. >
At a stop, the transmission is automatically
shifted down to the first gear.
> Shortly before the spee d falls below a gear-
dependent minimum speed, the transmis-
sion automatically down shifts without your
intervention.
Quick downshifting: even in sequential mode,
you can skip over several gears in order to
achieve an optimum acceleration. To do so,
depress the accelerator past the resistance
point.
To return to automatic mode, push the selector
lever to the right.
Gear shifting
Upshift or downshift usin g the selector lever or
the shift paddles. You do not need to lift your
foot off the accelerator when doing so.
Using the selector lever
> To upshift, pull the sele ctor lever toward the
rear.
> To downshift, push it toward the front.
Using the shift paddl es on the steering
wheel
You can also shift manua lly using two shift pad-
dles on the steering wheel. The shift paddles
allow you to shift gear s quickly since both
hands can remain on the steering wheel.
> When you use the shift paddles on the
steering wheel to shift gears in automatic
mode, the transmission switches to manual
mode.
> If you do not accelerate or shift gears using
the shift paddles for a certain amount of
time, the transmission switches back to
automatic mode if the selector lever is in
position D.

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 specifie d speed, the system
brakes the vehicle when the engine braking
effect is insufficient on downhill gradients.
Do not use cruise control when driving at
constant speed is prevented by adverse
conditions, e.g. winding roads, dense traffic or
poor road conditions due to, e.g., snow, rain, ice
or loose surfaces. Otherwise, you could lose
control of the vehicle and cause an accident as a
result. <
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you drive at very low engine speeds for an extended
period.

Maintaining current speed
Briefly press 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, arrow 1, 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.

> When the automatic transmission selector
lever is moved into the neutral position.
> When the selector lever of the Sports auto-
matic transmission with double clutch is
moved into the neutral position.
> When DTC is activate d or DSC is deacti-
vated.
> When DSC or ABS is intervening. Cruise control is not deactivated by depressing
the accelerator pedal.
Once the accelerator
pedal is released, the st ored speed is achieved
again and maintained.

Active Cruise Control
The concept
With Active Cruise Cont rol, you can select a
desired speed which is not only automatically
maintained when driving on open roadways, but
also varied to maintain a selected distance set-
ting as slower traffic is encountered.
Active Cruise Control is a technological
advance over the familiar cruise control and is a
welcome relief from the constant adjustment of
speed that can accompany driving in traffic on
highways or other high -speed thoroughfares.
Especially on longer trips, the system can
reduce fatigue and tension, while increasing
your enjoyment of driving. Please use it safely
and responsibly.
Within the limits of its capability, the system
automatically adap ts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be main tained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setti ng, the system automat-
ically decreases the thro ttle setting and lightly
applies the brakes if necessary. The vehicle
brake lamps will automatically illuminate to sig-
nal a following driver to take action. In addition,
it may be necessary for the vehicle or the driver
to downshift, depending on the kind of trans- mission your vehicle is equipped with, to main-
tain the distance setting
selected. If the vehicle
ahead speeds up or when the lane ahead
becomes clear, your vehi cle will accelerate to
the speed you have selected by increasing the
throttle setting and shifting gears automatically
or by the driver as needed. Your selected speed
will be held when driving downhill, too.
Since this Active Cruise Control system is a
new technology and operates differently from
conventional cruise co ntrol systems which you
may be accustomed to, you are strongly urged
to read all of the pages relating to this system
before use. Pay special attention to the System
limitations section beginning on page 80.
Braking sensation
>If you step on the brake pedal while the sys-
tem is braking, peda l sensation will be
slightly different from the usual.
> Possible noises during automatic braking
are normal.
Manual transmission
You can shift gears while cruise control is acti-
vated. The system is deactivated when you
drive at very low engine speeds for an extended
period.
Range of applications
The minimum desired speed is 20 mph or
30 km/h, the maximum desired speed is
110 mph or 180 km/h.
As with conventional cruise control sys-
tems, Active Cruise Control in no way
diminishes or substitutes for the driver’s own
personal responsibility, alertness and aware-
ness in adjusting speed, braking or otherwise
controlling the vehicle. The driver should
decide when to use the system on the basis of
road, traffic, visibility, and weather conditions.
Active Cruise Control is intended for use on
highway-type roadways where traffic is moving
relatively smoothly. Do not use this system in
city driving; heavy traffic such as during rush
