A CC no t avai la bl e
The text message ACC n ot av aila bl e appears, for examp le, if the
temperature of the brakes is excessive. Adaptive Cruise Contro l is
temporari ly not available . A warning tone sounds as a reminder.
A CC no t avai lable!
The text message ACC not avai la ble! appears in the event of a
malfunction. Adaptive Cruise Control is turned off. A warning tone
sounds as a rem inder. Have the system inspected by a qua lified
dea lership.
A CC sen sor bloc ked
The text message AC C se nsor b lo cked appears when the ACC
System does not detect any objects over an extended time period .
For the time being, the distance to vehicles up ahead is not being
controlled. The ACC system is not switched off, so increased a lert­
ness is required. The following may be reasons for the text message
ACC sensor blocked:
• The ACC sensor is d irty. The ACC system is not reacting, or is not
reacting correctly, to vehicles trave ling ahead .
• It is possible that you are dr iving on a road with very light traffic
without anything at the side of the road (e.g. guard rai ls, traffic
s igns, trees) . As soon as a vehicle is detected by the system aga in,
it returns to its control range and the text message disappears .
The ACC sensor is located in the area under the front license plate .
If there is a loss of operation due to heavy contamination, this area
should cleaned to restore proper operation.
A CC se nso r blo cked !
The text message ACC sen sor blocked! appears when the ACC
System can no longer accurately detect vehic les moving up ahead
in your lane of travel. Adapt ive Cruise Cont rol is tu rned off . A
warning tone a lso sounds as a reminder.
T o decide whether it is necessary to switch off the ACC (ACC sensor
b locked!) o r if it is on ly a temporary condition (ACC sensor blocked),
Controls and equip ­
ment
the system will also takes into consideration the outside tempera ­
t ure and/or the windshield wiper operation.
The ACC sensor is dirty or blocked (e.g. leaves, snow).
The ACC sensor is located in the area under the front license plate .
I f the ACC sensor is d irty or blocked, clean the area to restore system

you must always apply the footbrake before and while moving the
lever out of
N.
D -Normal position for driving forward
Position Dis for normal city and highway driving. It ranges from zero
to top speed and all six gears shift automatically, depending on
engine load, driving speed and automatically selected shift
programs.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the
lever to
D out of N.
In certain circumstances it may be advantageous to temporarily
switch to the manual shift program to manually select gear ratios to
match specific driving conditions=>
page 170.
S -Sport position
Select this position for sportier performance. In this position, the
transmission will not upshift as soon, allowing the vehicle to use the increased power available at higher engine speeds to achieve live ­
lier acceleration.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the lever to
S out of N.

Kick -down
T he kick-down feature allows the vehicle to genera te
maximum accelera tion.
When you press the acce lerator pedal beyond the resistance point
that is reached at ful l throttle, the transmission wi ll select a lower
gear ratio based on vehic le speed and engine RPM . The engine RPM

Controls and equip ­
ment
as you continue to press the acce lerator pedal beyond this resis ­
t ance poin t.
& WARNING
Be careful when u sing the ki ck -down feature on slippery road s.
Rapid acceleration ma y cause the vehicle to skid . •
Dynamic shift program (DSP)
T he aut omatic tr ans mission is electro nically c ontrolle d.
The transmission is se lf adapting and will automaticall y select the
b est shi ft program su ited to the driving conditio ns and driving style.
The transmission will select one of the
e conomy programs when
you drive at a s teady speed or a g radually changing speed without
heavy acceleration. This achieves optimum fuel efficiency, with ear ly
upshifting and delayed downshifting .
The trans mission will au tomatically select the
sporty shift progra ms
when you drive at higher speeds, or with heavy acce leration and
frequent ly cha nging speeds . Upshifts ar e delayed t o make f ull use
of engine power . Downshifting takes place at higher engine speeds
than in t he ec onomy p rograms .
The selection of the most su itable shift program is a continuous,
automatic process . The driver can a lso make the transmission
sw itch to a sporty progra m by
quickly pressing down the gas peda l.
This causes the transmission to shift down to a lower gear to
achiev e rapid acc elerati on, e.g . fo r q uickly pass ing another vehicle .
You do not need to press the gas pedal into the kick-down range.
After the transm ission has upshifted, the original progra m is
selected according to your driving sty le.
An additiona l shift program allows the automatic transmission to
select the proper gear fo r uph ill and downhi ll gradients.
This prevents the transmission from upshifting and downshifting unnecessa rily o n hills . The transm ission wi ll shift down to a lower _,.

When accelerating, the transmission will automatically shift into
gears 1 , 2, 3, 4 or 5 before the engine reaches its maximum RPM .
If you apply a light throttle when accelerating, tiptronic® will auto ­
matically shift from 1st to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or unti l the driver shifts into 2nd gear .
If you take your foot off the accelerator peda l 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 downshifting is interrupted as soon as
you apply the thrott le again .
[ i ] Tips
• When you shi ft into the next lower gear, the transmission will
downshift only when there is no possibi lity of over -revving the
engine.
• When the kickdown comes on, the transmission wil l shift down
to a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic® is inoperative when the transmission is in the fai l-safe
mode. •
