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
l ever positio n
The selector lever position engaged appears
next to the se lector lever as we ll as in the in­
strument cluster display.
P- Park
In this selector lever position the transmis­
sion is mechanically locked. Engage P on ly
when the vehicle is
completely stopped q .&.
in Driving the automatic transmission on
page 110.
To shift in or out of positio n P, you must first
press and hold the brake pedal and then press
the re lease button in the selector lever handle
while moving the selector lever to or from P.
You can shift out of this position only with the
ignition on.
R - Reverse
Select R only when the vehicle is at a full stop
and the engine is running at idle speed i:> & in

Before you move the se lector lever to R, press
both the button in the handle of the selector
lever
and the brake pedal at the same time .
When the ignition is on, the backup lights illu­
minate when the selector lever is moved into
R. ..,.

194 Intelligent technology
vehicles with adaptive cruise control*, the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
smal l.
Anti -slip regulati on (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerate and drive up hills.
Electronic diffe rential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other wheels .
This function is available up to abo ut 75 mph
(120 km/h) .
I n extreme cases , ED L automat ic all y switches
off to help keep the brake on the braked whee l
from overheating . EDL will switch on again au­
tomatically when conditions have returned to normal.
Dynamic st eering*
On vehicles with dynamic steering* , ESC helps
stabilize the steering in critical situations .
Electronic interaxle differential lock */
s elective whe el torque control *
The electronic in teraxle d iffe ren tial lock (fro nt
wheel drive) or the select ive whee l torq ue
control (a ll-wheel drive) operates when driv­
ing throug h curves . The front whee l on the in­
side of the curve or both wheels on the inside
of the curve are braked selectively as needed.
T his minimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when d rivi ng in wet or snowy conditions.
_& WARNING
- E SC, ABS, ASR, EDL, dynamic steering*
and the E lec tronic interaxle differentia l lock
*/se lective whee l torque control*
cannot overcome the laws of physics.
This is especially important on slippery
or wet roads .
If the systems beg in acting
to stabilize your veh icle, you should im­
mediately chang e you r speed to match
the road and t raffi c conditions. Do not
let the increased safety provided by
these systems temp t you to take risks.
Doing so will increase the risk of a loss of
veh icle cont ro l, collision and serio us per­
sonal injur ies.
- Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and o n slippery or wet roads, and
when dr iv ing too close to vehicles up
a head . ESC, ABS, the brake ass ist sys­
tem, ED L, ASR, dynam ic steeri ng* and
the Electronic in terax le different ial
loc k*/se lective whee l torque control*
cannot prevent collisions .
- Always accelerate wi th spe cial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
(D Tips
- ABS and ASR only wo rk correctly when
all four wheels are equipped with identi­
cal tires . D ifferent tire si zes can lead to a
reduction in engine powe r.
- You may hear noises when the systems descr ibed are working.
- If the ind icator light
Bl or fJl1 (USA
mode ls)l iiJ (Canada models) appears,
there may be a malfunction
¢ page 19,
¢page 19 .

-If the brake booster is not working, the
brake pedal must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electromechanical
power assist, dynamic
steering
The electromechanical power assist helps the
driver when steering .
Power steering adapts electronically based on
the vehicle speed.
Indicator lights and messages
• Steering defective! Stop the vehicle
If this indicator light turns on and stays on
and this message appears, the power steering
may have failed.
Do
not continue driving. See your authorized
Audi dealer or other qualified repair facility
for assistance .
'y. ij Steering: System fault You can continue
driving
If the indicator light turns on and the mes­
sage appears, the steering may be more diffi­
cult to move or more sensitive than usual. The
steering wheel may also be at an angle when
driving straight .
Drive slow ly to your authorized Audi dealer or
qualified workshop to have the malfunction
corrected.
' :r- ij Dynamic steering: Initializing
If this d river message appears and the indica­
tor light is flashing on the instrument panel,
dynamic steering* is being reinitialized. After
starting the engine, the steering whee l w ill
move slightly. Re-initialization might be nec­
essary if the steering wheel was moved hard
to the left and right while the vehicle was not
ev1 moving . The display goes out as soon as initi-
"' 8 alization is complete .

corrected.
_& WARNING
Have the dynamic steering* system mal­
function repa ired as soon as possible by an
authorized Audi dealer or qualified work­
shop -risk of acc ident!
(D Tips
If the . or (;r, ij ind icator light only stays
on for a short time, you may continue driv­ ing .
- The dynamic steering* stability systems
are not available in the event of a system
malfunction.
- For additional information on dynamic
steering*, refer to¢

Driving with your
quattro
Applies to veh icles: w it h all -w hee l drive
-
With all-wheel drive, all four wheels are driv­
en.
General information
With all-wheel drive, power is distr ibuted to
all four wheels. This happens automatically
depending on your driving style and the road
cond it ions at the time. See also
Qpage 193.
A center differential distributes the driving
power variably to the front and rear axle.
It
works together with selective wheel torque
control, wh ich activates when driving through
curves ¢
page 194. With the sport differen­
tia l*, power distribution to the rear wheels is
variable and can be adjusted with drive se lect
¢ page 100.
The all-whee l drive concept is des igned for
high engine power. Your vehicle is exception­
ally powerful and has excellent driving charac­
teristics both under normal driving conditions
and on snow and ice. Always read and follow
safety precautions ¢

26 6 T ire s and whee ls
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
secure ly and that the brake system functions
correctly .
In ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
~page 294.
_& WARNING
Improperly tig htened o r maintained whee l
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tighten ing
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the veh i­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
@ Note
The spec ified torq ue fo r the wheel bo lts is
90 ft lb (120 Nm) w ith a toleran ce of± 7,4
ft lb(± 10 Nm). Torque wheel bo lts diago- nally
. After changing a whee l, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
i zed Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equ ipped w ith low aspect
r atio tires . These tires have been tho roughly
tested and been se lected specifically for your
model for their superb perfo rmance, road fee l
and hand ling under a variety of d riving cond i­
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or less in the tire's s ize
designation. The nume ra l represen ts the ra tio
of the tire's sidewall height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low- aspect-r atio tires is
p ar ticu la rly s ens iti ve to improper infl ation
p re ss ure. I t is th erefore im portant th at low
as pect ratio tires are inflated to the specified
pressure and that the inflation pressu re is
r e gularl y che cked and mainta ined. Tir e pre s­
su res should be ch ecked at least onc e a
month and alwa ys bef ore a long trip
~ page 249, Checking tire pressure.
What you can do to a void tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes, curbs, gull ies
o r r idges on the road, pa rticularly if the tire is
u nderinfla ted .
In order to minimize the occurrence of impact
damage to the tires of you r vehicle, we recom­
mend that you observe the follow ing p recau ­
tions:
- Always ma inta in recommended inflation
pressures. Check your tire pressure eve ry
2,000 miles (3,000 km) and add air if neces­
sary .
- Dr ive carefully on roads with potholes, deep
gullies o r ridges. The impact from dr iv ing ..,.

A WARNING 1=
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed. When one
front wheel is lifted off the ground, plac­
ing the Automatic Transmission in P
(Park) will
not prevent the vehicle from
moving.
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the jack
and the replaced tire in the luggage com­
partment
¢ page 132.
{!) Tips
Before changing the wheel, you must acti­
vate the jacking mode, so that the auto­ matic controls for the Adaptive Air Sus­
pension* do not make it more difficult to
lift the vehicle with the jack¢

intended for use in a specific direction
When using a spare t ire with a tread patter n
intended for use in a spec ific d irection, please
note the following :
- The d irect ion of rotation is marked by an ar­
row on t he side of the ti re .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the t ire will not be able to
achieve its optimum performance cha racte r­
istics w it h regard to aquap la ni ng, no ise and
wear .
- We recommend that you pay part icu lar at­
ten tion to th is fact during we t wea ther and
t ha t you adjust your speed to match road
conditions .
