to the traffic situation is absolutely necessary. The following may be
reasons why the message
ACC functionality limited appears:
• The ACC sensor is dirty . The ACC system is not reacting, or is not
reacting correctly, to moving vehicles up ahead in your lane of travel.
• There may be very light traffic on and there is nothing that marks
the side of the road (for example, guard rails, traffic signs, trees) . As
soon as a moving vehicle up ahead is detected aga in, ACC becomes
active again and the message disappears.
Th e ACC sensor is located in the area under the front license plate.
If
the ACC sensor is dirty or blocked, clean the area to restore system
operat ion.
ACC not available
The text message ACC not available appears, for example, if the
temperature of the brakes is excessive. Adaptive Cruise Control is
temporarily not available. A warning tone sounds as a reminder.
ACC not available!
The text message ACC not available! appears in the event of a
malfunction. Adaptive Cruise Control is turned off. A warn ing tone
so unds as a reminder. Have the system inspected by a qualified deal
ership.
ACC sensor blocked !
The text message ACC sensor blocked! appears when the ACC System
can no longer accurately detect vehicles moving up ahead in your lane
of travel. Adaptive Cruise Control is turned off. A warning tone also
so unds as a reminder.
To decide whether it is necessary to switch off the ACC (ACC sensor
blocked
!) or if it is only a temporary condition (ACC Functiona lly
limited), the system w ill also takes into consideration the outside
temperature and/or the windshield wiper operation .
Th e ACC sensor is dirty or blocked (e.g. leaves, snow) . The ACC sensor is located in the area under the front
license plate. If
the ACC sensor is dirty or bloc ked, clean the area to restore system
operation .
EPB activation
The text message EPB activation appears if emergency braking was
man ua lly initiated with the Electromechanical Parking Brake (EPB).
The Adaptive Cruise Control is turned off . Th is is accompanied by a
wa rning tone.

Adaptive Cruise Control -
----------------
In certain situations, the braking power of the Adaptive Cruise
Control is not enough to maintain an adequate distance to the vehicle
up ahead. In these situations, the Adaptive Cruise Control calls the
driver to take action.
The
driver intervention prompt alerts you visually and audibly to take
over.
• A red vehicle is shown in the instru ment cluster display

• Th e text
DISTANCE! appears in the status line.
• The indicator light
c:::>uuc:::> in the speedometer blinks red.
• A warning tone sounds .
[I) Tips
• If the Adaptive cruise control initiates braking, the hydraulic brake
system is under pressure . Therefore, the brake pedal distance is
shorter and the pedal "feels" harder .
• Adaptive Cruise Control is switched
off after pressing the foot
brake. The speed saved up this point can be resumed.
• To resume the saved speed, release the brake pedal and press the
control lever=>
page 124, "Turning Adaptive Cruise Control off
temporarily".
• If you use the accelerator to go faster than the speed of the
vehicle ahead of you, the
driver intervention prompt will not be
accompanied by a warn ing s ignal.
• If the speed you previously set is exceeded, the indicator light in
the speedometer will switch
off .•

The Adaptive Cruise Control works within limits that are also related

_& WARNING
• Unintended vehicle movement can cau se serious injury.
- When the selector lever is in a driving position, the vehicle may creep, even at idle speed. Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transm itted to the wheels as soon as a driv ing
po sition i s engaged.
- Do not accelerate while selecting a driv ing position . At this
time the engine must be at idle speed so that undue stress i s
not placed on the clutches in the transm iss ion.
- Remember : • even when stopped briefly with the automatic
transmission in "D", "S" or "R" , engine power is being trans
mitted to the wheels . Your vehicle could "creep " forward or
backward. When stopped, keep the brake pedal fully
depre ssed and use the parking brake if neces sary to keep the
vehicle from rolling .
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi
tion.
• Never shift into "R " or "P " when the vehicle is in motion .
• Never get out of the d river's seat when the engine is running.
• If you must get out of the vehicle , move the selector lever
securely into the P position and apply the parking brake firmly .
• If the engine must remain running, never have any driving

Kick-down
The kick-down feature allows the vehicle to generate
maximum acceleration .
When you press the accelerator pedal beyond the resistance point
that is reached at full throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine RPM. The engine RPM
will be controlled to produce maximum vehicle acceleration as long
as you continue to press the accelerator pedal beyond this resistance
point .
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •

The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best sh ift p rogram suited to the driv in g conditions and driving style.
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speed without heavy
acceleration . This ach ieves optimum fuel efficiency, with early
upshifting and de layed downshifting.
Th e transmission will automatically select the
sporty shift programs
when you dr ive at higher speeds, or w ith heavy acceleration and

The selection of the most suitable shift program is a continuous,
automatic process. The driver can also make the transmission switch
to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to achieve
rap id acceleration, e.g . for quic kly passing another vehicle. You do
not need to press the gas peda l into the kick-down range. After the
transmission has upshifted, the original program is selected
according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uph ill and downh ill gradients .
This keeps the transmission from shifting up and down unnecessarily
on hills . T he transmission will shift down to a lower gea r when the
driver presses the brake pedal on a downhill gradient. This makes use
of the braking effect of the engine without the need to shift down
manually. •

To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into

If you apply a light throttle when acce lerating, tiptronic ® wi ll auto

throttle , the transmission will stay in 1st gear until near maximum
RPM is reached, or until the driver shifts into 2nd gear.
If you take your foot off the accelerator pedal when driving down a
steep incline , tiptronic ® will downshift from the selected gear into
the next lower gear until it reaches 1st gear, based on road speed and
engine RPM. Automatic downshift ing is interrupted as soon as you
