Automatic Transmission
multitronic ®, S tronic ®,
tiptronic
Introduction
App lies to vehicles: with multitro ni c/S tronic/t iptronic
The automatic transmission is controlled elec­
tronically . The transmission upshifts or down­
shifts automatically depend ing 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
de lay the downshifts to g ive better fuel econ­
omy.
The transmission switches to a sporty mode after a k ick-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 a lso se lect the gears
manually (t iptronic mode ) ¢ page 109.
Various automatic transm issions may be in­
stalled, depend ing on the model :
multitronic® transmission
The multitronic ® transmission is a continuous­
ly variable transmission. Power is transferred
using a multidisk clutch. In contrast to con­
ventional automatic transmissions using shift­
ing operat ions, the transmission ratio in the
continuously variable transmission is changed
continuously. This opt imizes 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
r eplace the torque converter used in conven­
tional automat ic transmissions and allow the
vehicle to accelerate without a noticeable in­
terruption in traction.
Automatic Transmission 105
tiptronic transmission
In the tiptronic transmission, power is trans­
ferred by a torque converter .
Selector lever positions
Applies to vehicles: wit h mult itronic/5 tro nic/tiptro nic
Fig. 111 Disp lay in the instrument cluster: selector
l ever pos itio n
The selector lever position engaged appears
next to the selector lever as well as in the in­
strument cluster display.
P -Park
In this selector lever position the transmis­
sion is mechanically locked. Engage P only
when the vehicle is
completely stopped¢&.
in Driving the automatic transmission on
page 108.
To shift in or out of position P, yo u must first
press and ho ld the brake pedal and then press
the release 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¢ A in
Driving the automatic transmission on
page 108.
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. .,.

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , electronic dif­
ferential lock (E DL) and e lectronic interaxle
d ifferential lock*. ESC is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru ~ fig . 177 . Be sure to switch
ASR on again when you no longer need less
traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control* , the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it eas ier to
s tart, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases , EDL automatically switches
off to help keep the brake on the braked wheel
from overheating. EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Intelligent technology 193
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
whee l drive) or the se lective wheel torque
cont rol (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more precise driving through
curves . Th e applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-
-ESC, ABS, ASR, EDL and the electronic in­
teraxle differential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your vehicle, you should immedi­
ately change your speed to match the
road and traffic conditions. Do not let
the increased safety provided by these
systems tempt you to t.;1ke risks. Doing
so will increase the risk o f a loss of vehi­
cle control, collision and serious personal
injuries.
-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 on slippery or wet roads, and
when dr iving too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the elec tronic inter­
axle differential lock function* cannot
prevent collisions .
- Always accelerate with special care on
even, smooth surfaces 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 red uce the risk of loss of ve -
hicle control. .,.

@ Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
veh icles with all-wheel dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of whee l bolts is matched to the
factory insta lled 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 f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
<=> page 287.
.&_ WARNING
Improperly tightened or maintained wheel
bolts can becom e loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clea n so the
w heel bolts can t urn easily and be prop ­
erly t ightened .
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while d riving if greased or
oi led, even if tightened to the specif ied
torque.
- Only use whee l bolts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Always maintain the co rrect tighten ing
torq ue for the wheel bo lts 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 vehi­
cle is moving. If the tightening torque is
too high, the whee l bolts and threads
Tire s an d wheel s 257
can be damaged and the whee l can be­
come loose.
(D Note
The specified torque for the whee l bolts is
90 ft lb (120 Nm) with a tolerance of± 7,4
ft lb(± 10 Nm) . Torq ue whee l bolts diago­
nally. After changing a whee l, the torq ue
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
You r Aud i is facto ry-equ ipped w it h low aspect
ra tio tires. These tires have been tho ro ughly
tested and been se lec ted spe cifically for you r
model for their superb perfo rmance, road fee l
and handling under a variety of driving condi­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or le ss in the tire's s ize
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage. Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-aspect -ra tio tire s is
particularly sens it iv e to improper inflation
pressure. It is therefore important that low
aspect ratio t ires are inflated to the specified
pre ssure and that the inflation pressur e is
regularly che cked and maintain ed. Tire pre s­
s ures should be checked at least on ce a
m onth and alwa ys before a long trip
¢ page 246, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damage d mo re
easily by impact w ith potholes, curbs, g ull ies
or ridges on t he road, partic ularly if the tire is
u nderinflated.

tance
off the road. Turn off the engine,
turn the emergency flashers on and use other warning dev ices 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 traff ic.
- T o help p revent the veh icle from mov ing
sudden ly and possibly slipping off the
ja ck, always fully set the parking b rake
and bloc k the whee l diagona lly opposite
the whee l being changed. When one
front whee l is lifted off the gro und, plac­
ing the Automat ic Transmiss ion in P
(Park) will
not prevent the vehicle from
moving.

268 What do I do no w?
P uttin g on the spare wheel
.. Lift the spare wheel and ca refully slide it
over the alignment pin to guide it in place
¢ (D .
.. Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bolts
slightly.
.. Remove the alignment pin and insert and
t ighten the remaining wheel bolt slightly
L ike the rest .
.. Turn the jack handle cou nter -clockw ise to
lower the vehicle unt il the jac k is fully re­
leased.
.. Use the wheel bolt wrench to tighten all
wheel bolts firmly¢
page 265 . Tighten
them
crosswise, from one bolt to the (ap­
proximately) opposite one, to keep the
wheel centered.
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you .
(j) Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or t ighten
the wheel bolts .
- Pull the reversible blade from the screw­
driver before you use the hexagonal
socket in the handle to turn the wheel bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the right way
¢ page 268.
-The wheel bolts should be clean and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both the whee l
and the h ub. Remove al l dirt from these
surfaces before remo unting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed in the right direction .
Using a sp are t ire w ith a tre ad pattern
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 direct ion of rotation is marked by an ar­
row on the side of the tire .
- If the spare tire has to be installed in the in­
correct direct ion, use the spare tire only
temporarily s ince the tire will not be able to
achieve its optimum performance cha racter­
isti cs wit h regard to aquap lan ing, no ise and
wear .
- We recommend that you pay part icu la r at­
t ention to th is fact d uring wet wea ther and
t ha t you adjust you r speed to match road
conditions .
- Replace the fl at tir e with a new one and
have it insta lled on you r vehicle as soon as
possible to restore the handling advantages
of a u nidirectional tire .
Notes on wheel changing
Please read the information¢ page 251, New
tires and replacing tires and wheels
if you a re
going to use a spare tire which is different
from the ti res on your vehicle .
After you change a tire:
- Check the tire pre ssure on the spar e imm e­
diately after install ation.
- Have th e whe el bolt tight ening torqu e
c hecked with a torque wrench as soon a s
pos sible by your author ized Audi de aler or
a q ualified service stat ion.
- With steel and allo y wheel r im s, the wheel
bolt s ar e cor re ctl y tightened at a torque of
90 ft lb (1 20 Nm ).
- If you noti ce th at the wheel bolts are cor­
roded and diffi cult to turn while changing
a ti re , they should be repl aced before you
check the t ightening torque. .,..
