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 exce edin g the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­
proximately 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./.
turns off when the speed decreases be low the
stored maxim um speed.
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you
may want to do so incl ude driving in a co untry
with a general speed limit or if there is a
specified maximum speed for winter tires.
@ Tips
Even though your vehicle is equipp ed w ith
a speed warning system, you sho uld still
watch the speedometer to make sure you
are not driv ing faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
.., Select: !CAR ! function button> (Car)* sys­
tems

A WARNING
--Always pay attent ion to traffic even when
the cruise control is switched on. You are always responsible for your speed and
the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise contro l
should not be used in the city, in stop­
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
p lan ing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in constr uction zones .
- Please note that inadve rtently "resting"
your foot on the accelerator pedal causes the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be sw itched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models)/ ... (Canadian models)
is on.
(D Tips
The brake lights illuminate as soon as the
brakes decelerate automatically .
Changing speed
Applies to vehicles: with cruise control
• To increase/decrease the speed in incre­
ments, tap the lever in the
0 10 direction

• To increase/decrease the speed quick ly, hold
the lever in the
010 d irect ion until the de­
sired speed is displayed .
You can also press the accelerator pedal down
to increase your speed, e.g . if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler- ator pedal. ..,.

your p re ferences in the
Individual mode . F o r
examp le, you ca n combine settings such as a
sporty en gine t uning with comfortab le steer­
ing.
A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous personal injury.
Description
The follow ing systems a re affected by dr ive
se lect:
Engine and transmission
Depending on the mode, the engine and the
tra nsmission respond quicker or in a more bal­
a nced manner to acce lerator pedal move ­
men ts. I n the sporty dynamic mode, the
tra nsmission sh ifts at highe r RPMs.
Air suspension*
The adaptive air suspension/adaptive air sus­
pe nsion sport*
(A ir suspension in the MMI) is
an e lec tronically con tro lled air suspens ion and
d ampi ng sys tem. Th ey are adjusted depe nd­
ing on the se lected driving mode, the dr ive r's
steer ing, br aki ng and acceler ation inpu t and
the road s urface, ve hicle speed an d load . A
sporty se tting is generally use d in vehicl es
with a daptive ai r suspension s port* .
The vehicle clea rance v aries depe nd ing on the
se lec ted mode and the speed . T
he hig hway setting is act ivated automat ically
whe n you drive above 7 5 mph (120 km/ h) for
m ore than
30 seconds in the Auto or Dynamic
mode. The g ro und clearance is increased a uto­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds .
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steering that
moves easily, like the steer ing in comfort
m ode, is best suited to lo ng drives o n a hig h­
way. In contrast, dynamic mode provides spo rty, direct steer ing .
The following applies to veh icles with dynamic
steering* : the steer ing rat io changes based on
vehicle speed in orde r to ma inta in optimum
stee ring effort for the dr ive r at all times . This
sets the stee ring to be less sens itive at h igher
speeds in order to provide improved vehicle
co ntrol. At reduced spee ds, howeve r, s teer ing
is mo re d ire ct in order to keep the stee ring ef ­
fort as minima l as poss ible when the drive r is
mane uve rin g the vehicle. At low and average
speeds, dynamic steering addit iona lly pro ­
vides more responsive steeri ng performance.
Sport differential*
As a component o f the all whee l dr ive system
(quatt ro)
¢ page 200, the Sport differential *
dist ributes t he d riving power to the rear ax le
depend ing on the sit uat ion . The distrib ution
of power var ies depending on the selected
mode, from balanced (comfo rt) to agile (dy­
nam ic) . The goal is a h igh level of ag ility and
abili ty to acce lera te on curves . Th e veh icle is
very respons ive to stee ring.
Curve light*
The curve light adapts to driving on curves.
The pivoting 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 contro l
also responds to the driv ing behavior o f the

Engine sound *
The sou nd of the engine is adapted to these­
lec ted mode and ranges from subtle to sporty.
(D Note
- Make sure there is eno ugh clearance
above and below the veh icle when park­
i ng. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load condi ­
tions and changes to the driving modes,
which can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on­
ly tie the vehicle down at the running
surface of the tires, which is the outer
circumference. Securing the vehicle at
the axle components, suspension struts
or tow ing eyes is not permitted because
the pressure in the air suspension struts
can change d uring transport. The vehicle
may not be sec ured s uff icient ly if this
happens.
-If you are going to tow a trailer, you
must activate the trailer ope rat ion mode
¢page 208 .
@ Tips
-In some mode ls, the m axim um vehicle
speed can on ly be reached in the Auto
and Dynami c modes.
- Se lecting the Dynami c mode results in
sporty shifting characteristics . The S
gear position engages automatically .
- In vehicles with sport differential*, the
D ynamic mode is deactivated when tow ­
ing a trai ler .
- In vehicles that have dynamic steering*,
operating noise is heard when starting or

Automatic Transmission
S tronic, tiptronic
Introduction
The automatic transmission is controlled elec­
tronically. The transmission upsh ifts or down­
shifts automatically depending on which drive
program is selected.
When a
moderate driving style is used, the
transmission selects the most econom ica l
driving mode. It will then change up early and
delay 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) ¢ page 113.
Various automatic transmissions may be in­
stalled, depending on the model :
S tronic transmission
The S tronic is a dual-clutch transmission.
Power is transferred using two clutches that
work independently from one another . They
replace the torque convert er used in conven­
tional automatic transmissions and allow the
veh icle to accelerate without a noticeable in­
terruption in traction.
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter .
