Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed .
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­
prox imately 3 mph (3 km/h) . An indicator
light . (USA models)/ . (Canada models) in
the instrument cluster display also turns on at
the same time . The indicator light
a;m
turns off when the speed decreases below the
stored maximum speed.
Sett ing a th resho ld is recommended if you
wou ld like to be reminded when you reach a
certain maximum speed. Situations where you
may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires.
(1} Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you are not driving faster than the speed limit.

Description
The vehicle setup in each mode depends on
the veh icl e's featu res. The engine, t ransm is­
sion, stee ring, reve rsible sa fe ty belt tension­
e rs a nd adap tive air su spension are alw ays in­

men ts. In the sporty dyn ami c mode, the
tra nsmission sh ifts at highe r RP Ms.
Air suspension*
The adaptive air suspens ion/adaptive air sus­
pension spor t*
(Air suspen sion in the MM I) is
a n e lec tronic ally con trolled air suspension and
da mpi ng sys tem. They are adjus ted depend­
ing on the se lected driving mode, the drive r's
steeri ng, braking an d acceleration input and
the road s urface, ve hicle speed and load. A
sporty setting is generally used in ve hicles
with adaptive air suspension sport*. T
he veh icle clearance varies depending on the
se lected mo de an d the speed .
T he highway setti ng is a ct ivated automatic ally
whe n you dr ive above 7 5 mph (120 km/ h) fo r
more than
3 0 seconds in the Auto or Dynamic
mode. The gro und clea rance is increased a uto ­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds.
Steering
T he s teer ing adap ts in terms of s teer ing effor t
and steering ratios . Indirect stee ring that
moves easily, like the steer ing in comfo rt
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides sporty, direct steer ing .
Sport differential*
As a component of the all whee l drive system
(quattro)

dist ributes the driving power to the rear ax le
depending on the sit uat ion. The distrib ution
of power var ies depend ing on the selected
mode, from balanced (comfort) to agile (dy­
nam ic) . Th e goal is a h igh level of ag ility and
ability to acce lerate on cu rves . Th e ve hicl e is
very res ponsive to stee ring.
Curve light*
The curve light adapts to driving on curves .
T he pivo ting act io n and the lighting are also
adapt ed to the mode .
Adaptive cruise control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise cont ro l

Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from sub tle to sporty . .,.

(D Note
-Make sure there is enough clearance
above and below the veh icle when park­
ing. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iving modes,
which can affect clearance .
- When t ransporting the veh icle on a car
carr ier, tra in, ship or by other means, on­
l y tie the veh icle down at the runni ng
su rface of the tires, which is the outer
ci rcumference . Secur ing the vehicle at
the axle components, s uspension struts
or tow ing eyes is not pe rm itted because
the pressu re in the air suspension struts
can change during transport. The vehicle may not be secured sufficiently if this
happens.
- If you are going to tow a trailer, you
must activate the trailer operation mode
<=> page 209.
{!) Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynami c modes.
- Selecting the
Dynami c mode results in
spo rty sh ifting character istics. The S
gear posit ion engages automatically.
- In vehicles with sport differential", the
Dynami c mode is deactivated when tow­
i ng a trailer.

Automatic Transmission
S tronic, tiptronic
Introduction
Applies to vehicles: with S tro nic/t iptronic
The automat ic transmission is controlled elec­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is se lected.
When a
moderate driving style is used, the
transmission selects the most economica l
driving mode. It will then change up early and
de lay the downshifts to give better fuel econ­
omy.
The transmission switches to a sporty mode
after a kick-down or when the driver uses a
sporty driving style characterized by quick ac­
celerator pedal movements, heavy accelera­
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) r:::> page 113.
Various automatic transmissions may be in­
stalled, depending on the mode l:
S tronic transmission
The 5 tronic is a dual-clutch transmission .
Power is transferred using two clutches that
work independently from one another . They
replace the torque converter used in conven­
tional automatic transmissions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter.
