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 provides maximum accelera-
tion.
Sport program and manual mode M/S
Push selector lever toward 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 situations, 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 speed falls below a gear-
dependent minimum speed, the transmis-
sion automatically downshifts 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 using 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 selector lever toward the
rear.
> To downshift, push it toward the front.
Using the shift paddles on the steering
wheel
You can also shift manually using two shift pad-
dles on the steering wheel. The shift paddles
allow you to shift gears 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.

danger that the fluid will freeze on the
windshield. If you do, your vision could be
obscured. Antifreeze should therefore be
added to the fluid, refer to Washer fluid.
Do not use the washers 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.
Therefore, keep it away from ignition
sources and only store it in the closed original
container that is kept out of reach of children;
otherwise, there is a risk of personal injury.

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 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.

Malfunction
The warning lamp lights up. A mes-
sage appears on the Control Dis-

tioning. You can continue your journey. Have
the system checked.
Active Cruise Control
The concept
With Active Cruise Control, 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 adapts the car's speed to that of a
slower vehicle in front of you. You can specify
the distance to be maintained from the vehicle
in front in four stages. For safety reasons, the
distance is speed-dependent. Based on your
selected distance setting, the system automat-
ically decreases the throttle 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 vehicle 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 78.
Braking sensation
> If you step on the brake pedal while the sys-
tem is braking, pedal 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
110mph or 180km/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
hour; on curvy, winding roads, slippery roads or
roads with sharp curves such as highway off-

ControlsDriving
The selected distance is displayed in the instru-
ment cluster.
Use good judgment to select the appro-
priate following distance given road con-
ditions, traffic, applicable laws and driving rec-
ommendations for safe following distance.
Otherwise, an accident risk could result. <
Deactivating cruise control
Press the lever upward or downward, arrow 3.
The displays on the speedometer disappear.
In addition, the system is automatically deacti-
vated:
> when the brakes are applied.
> when the speed is reduced to below
20 mph or 30 km/h due to a traffic situation. >
when the manual transmission is shifted
very slowly or shifted into neutral.
> when the automatic transmission selector
lever is moved into the neutral position.
> when the selector lever of the sport auto-
matic transmission with double clutch is
moved into the neutral position.
> when Dynamic Traction Control DTC is
activated.
> when Dynamic Stability Control DSC is
deactivated.
> when DSC or ABS is intervening.
> when the system does not recognize any
objects for a longer time, e. g. on infre-
quently traveled roads without a shoulder or
guard rails, or if the radar sensor is covered
with dirt, refer to page 77.
> when the parking brake is engaged.
When the system is deactivated, you
must brake the vehicle yourself and/or
maneuver as necessary; otherwise, there is a
risk of accidents.<
Warning lamp
The warning lamp lights up when
Active Cruise Control has been auto-
matically deactivated, for example
due to a driving speed below 20 mph or
30 km/h or a DSC intervention. A message
appears on the Control Display.
Resuming stored desired speed and
distance
Briefly press the button, arrow 4.
The stored speed and distance are regained
and maintained.
In the following instances, the stored speed is
deleted and can no longer be resumed:
> When driving stability control systems are
intervening.
> In cars with manual transmission: when you
shift gears very slowly or shift to neutral.
