You c an a lso a djust the setti ng according to
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

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 197, 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

Automatic Transmission
multitronic, 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 se lected .
When a
moderate driving style is used, the
transmission selects the most economical
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 als o se lect the gears
manually (tiptronic mode) q page 111.
Various automatic transmissions may be in­
stalled , depending on the model:
multitronic transmission
The multitron ic transmission is a continuously
variable transmission. Power is transferred us­
ing a multidisk clutch . In contrast to conven­
tional automat ic transm iss ions using shift ing
ope rat ions, the transmiss ion ratio in the con­
tinuously variab le transmission is changed
continuously. This optimizes the comfort level
and conserves fuel.
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 converter used in conven­
tional automatic transm issions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.
Automatic Transmission 107
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter.
Selector lever positions
Fig. 114 Disp lay in the instrument cluster: selector

The Automatic Shift Lock only functions when
the vehicle is stationary or at speeds below
1 mph (2 km/h).
At speeds above about 1 mph (2 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the N position.
A time delay element prevents the se lector
l eve r from locking when it is moved thro ugh
the N position (going from R to 0/5). The lock­
ing e lement will lock the selector lever if the
lever is left in N (Neutral) for more than ap­
prox imately 2 second, without the brake ped­
al being pressed.
R elease button
The release button on the selector lever pre ­
vents the lever from being accidenta lly shifted
into certain positions. Depending on the direc­
tion of the shift, the selector lever locks at d if­
ferent positions. The positions are h ighlighted
in the illustration

What impairs driving safety?
Safe driving is directly related to the condi­
tion of the vehicle, the driver as well as the
driver 's ability to concentrate on the road
without being distracted.
The driver is respons ible for the safety of the
veh icle and all of its occupants.
If your ability
to drive is impai red, safety r isks for everybody
in the vehicle increase and you also become a
hazard to everyone else on the road ¢
A.
Therefore:
.. Do not let yourself be distracted by passen­
gers or by using a cellular telephone.
.. NEVER drive when your driving ability is im­
paired (by medications, alcohol, drugs, etc.).
.. Obse rve all traffic laws, rules of the road
and speed limits and plain common sense .
.. ALWAYS adjust your speed to road, traff ic
and weather conditions .
.,. Take frequent breaks on long trips . Do not
drive for more than two hours at a stretch.
.. Do NOT drive when you are t ired, under
pressure or when you are stressed.
A WARNING
Impaired driving safety increases the risk
of serious personal injury and death when­
ever a vehicle is being used.

Fig. 144 Correct seat ing pos it ion
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the driver's seat to the
follow ing pos ition:
.. Adjust the driver's seat so that you can easi ­
ly push the pedals all the way to the floor
wh ile keeping your knee(s) slightly bent
¢.&_ .
.. Adjust the angle of the seatback so that it is
in an upr ight position so that your back
comes in full contact w ith it when you drive.
.. Adjust the steering wheel so that th ere is a
distance of at least 10 inches (25 cm) be­
tween the steering wheel and yo ur breast
bone
Q fig. 144. If not possible, see your au ­
thorized Audi dealership about adaptive
equipment .
.. Adjust the steering wheel so that the steer­
ing wheel and airbag cover points at your
chest and not at your face.
.,. Grasp the top of the steering wheel with
your elbow(s) slightly bent.
.. For adjustable head restra ints: Adjust the
head restraint so the upper edge is as even
as possible with the top of your head. If that
is not possible, try to adjust the head re­
straint so that it is as close to this position
as poss ible. Move the head restraint so that
it is as close to the back of the head as pos-
sible . .,.

Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are nec ­
essary, how they work and how to adjust and
wear them correctly .
.. Read a ll the information that fo llows and
heed all of the instructions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means avai lab le to reduce the risk of se­

dents. For your protection and that of
yo ur passenge rs, always co rrectly wear
safety belts when the vehicle is moving.
- Pregnant women, injured, or physically
im paired perso ns m ust also use safety
belts. Lik e all veh icle occup ants, they are
more like ly to be ser iously injured if they
do not wea r safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of five seating positions: two in the front and three in the rear. Each
seating position has a safety belt.
A WARNING
Not wea ring safety belts or weari ng them

Why safety belts?
Frontal collisions and the law of physics
Frontal crashes create very strong forces for
people riding in vehicles .
Fig. 147 Unbelted occupants in a ve hicle heading for a
wall
Fig. 148 The vehicle cras hes into the wall
The physical principles are simple. Both the
vehicle and the passengers possess energy
which varies w ith veh icle speed and body
weight . Engineers call this energy "kinetic en­
ergy."
The higher the speed of the vehicle and the
greater the vehicle's weight, the more energy
that has to be "absorbed" in the crash .
Vehicle speed is the most significant factor . If
the speed doubles from 15 to 30 mph (25 to
SO km/h), the energy increases 4 t imes!
Because the passengers of this vehicle are not
using safety belts¢
fig. 147, they will keep
moving at the same speed the vehicle was
moving just before the crash, until something
stops them - here, the wall ¢
fig. 148.
Safety belts 13 7
The same principles apply to people sitting in
a vehicle that is involved in a frontal collision.
Even at city speeds of 20 to 30 mph (30 to 50
km/h), the forces acting on the body can
reach one ton (2,000 lbs, or 1,000 kg) or
more . At greater speeds, these forces are even
higher.
People who do not use safety belts are also
not attached to their vehicle . In a frontal colli­
sion they will also keep moving forward at the
speed their vehicle was travelling just before
the crash . Of course, the laws of physics don't
just app ly to frontal collisions, they determine
what happens in all kinds of accidents and col­
lisions.
What happens to occupants not wearing safety belts?
In crashes unbelted occupants cannot stop
themselves from flying forward and being in­
jured or killed. Always wear your safety belts!

thrown forward
Fig. 150 A rear passenger not wearing a safety belt

Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or bracing themselves. Without the benefit of
safety restraint systems, the unrestrained .,..
