Introduction
Applies to vehicles: with mult itronic/5 tronic/tiptronic
The automatic transmission is controlled elec ­
tronically. The transmission upshifts or down­
shifts automatically depending on which drive
program is selected .
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
t ion, frequent changes in speed and trave ling
at the maximum speed.
If desired, the driver can also select the gears
manually (tiptronic mode) ~ page 91.
Various automatic transmissions may be in­
stalled, depending 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 operations, the transmission ratio in the
continuously variable transmiss ion 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
tiona l automatic transmissions and allow the ..,_

vehicle to accelerate without a noticeable in­
terruption in traction.
tiptronic transmission
I n the tiptronic transmission, power is trans­
ferred by a torque converter.
Selector lever positions

186 Intelligent technology
ESC includes and/or works together with the
anti-lock brake system (ABS), brake assist sys ­
tem, anti-slip regulation (ASR) , e lectronic dif­
ferential lock (EDL), dynamic steering" and
e lectronic interaxle differentia l lock* /selective
wheel torque control* . ESC is switched on all
the t ime. I n certa in s ituations whe n you need
l ess t raction, you can switch
off ASR by p ress­
i ng the bu tto n
[ru ¢ page 188, fig. 176 or
¢ page 188, fig. 177. Be sure to sw itch ASR
on aga in when yo u no longer need less t rac­
tion .
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braki ng. The veh icle can still be steered
even d uring h ard br aking. Apply ste ady p res ­
sure to the brake pedal. Do no t pump the ped­
a l. A pulsing in the brake peda l indicates t hat
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assis t system can decrease b ra ki ng
d ista nce. It increases braking power w hen the
d river p resses the brake pedal quic kly in eme r­
gency situations . You must p ress and hold the
brake peda l until the situation is over. In
vehicles w ith adapt ive cru ise contro l", the
brake assist system is more sensit ive if the
d ista nce detected to t he vehicle a head is too
small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start , accelerate and drive up hills.
Electronic differenti al lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if t he vehicle is equipped with
all-w heel drive*. This function is available up
to about 60 mph (100 km/h).
In extreme cases, EDL automat ica lly switches
off to help keep the bra ke on the braked whee l
from overheating. EDL wi ll switch on again au-tomat
ica lly when conditions have ret urned to
no rma l.
Dynamic steering*
On vehicles wi th dynam ic steering*, ESC he lps
st abi liz e the steer ing in cr itical situ ations.
Electronic interaxle differential lock* /
selective wheel torque control*
T he elec troni c int eraxle differentia l lock (front
whee l dr ive) o r th e se lec tive whee l torque
control (all-whee l dr ive) oper ates when dr iv ­
ing t hro ugh curves. The front wheel on the in ­
side of the c urve or both whee ls on the inside
of the c urve are b raked se lectively as needed.
This m inimizes sliding in the front wheels and
allows for more precise driving through
curves . The applicable system may not acti­
vate when dr iving in wet o r snowy cond itions.
A WARNING
- ESC, ABS, ASR, EDL dynam ic steering*
a nd the ele ct roni c interaxle d ifferential
lo ck* /se lective whee l torque con trol *
cannot ove rcome the laws of physics .
This is especially important on sli ppery
or wet roads.
If the systems beg in acting
to stabilize your veh icle, yo u should im­
mediately change your speed to match
the road and traffic conditions . Do not
let the increased safety prov ided by
these systems tempt you to take r isks.
Doing so will increase the risk of a loss of
veh icle cont ro l, col lision and ser ious pe r­
sonal injur ies.
- Always ada pt your speed to road, traffi c
a nd wea ther conditions. The r isk of los-
ing con trol of the vehicle i ncreases when
d riving too fast, es pec ia lly through
curves and o n slippe ry or wet roads, an d
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys­
tem, ASR, EDL dynam ic steer ing* and the

@ Tips
- If the . or
fT j indicator light on ly stays
on for a short t ime, you may continue
driving.
- The dynamic steering* stability systems
are not available in the event of a system
malfunction.

Driving with your
quattro ®
Applies to vehicles: with a ll-wheel drive
With all-wheel drive, all four wheels are driv­
en.
Gener al inform ati on
W ith all-wheel drive, power is distributed to
all four wheels . This happens automatically
depending on your dr iving style and the road
conditions at the t ime. See also
c:> page 185.
A center different ial distr ibutes the dr iv ing
power var iably to the front and rear axle . It
works together with selective wheel torque
control, which activates when driving throug h
curves
c:> page 186. With the spo rt d ifferen ­
tial*, power dist ribution to the rear wheels is
variable and can be adjusted with drive select
c:> page 113.
The all-wheel drive concept is designed for
h igh engine power. Yo ur vehicle is exception ­
ally powerful and has exce llent driving charac ­
teristics both under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions
c:> A .
Winter t ir e s
When driv ing in the w inter, your veh icle w ith
all-wheel drive has an advantage,
even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
a ll four
w heels . See also c:> page 250, Winter tires .
Intellig ent technolog y 191
Tire chain s
Where tire chains are mandatory on certain roads, this no rma lly also applies to veh icles
with all-wheel drive
c:> page 251, Snow
chains.
Replacing wheels /tires
Vehicles with a ll-wheel drive must always
have tires of t he same s ize. A lso avoid tires
with different tread depths . For detai ls see
page
c:> page 246, New tires and replacing
tires and wheels .
Off-Road driving?
You r A udi does no t have enough ground clear ­
ance to be used as an off-road vehicle .
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possib le . Also refer to
c:> page 194.
A WARNING
Always adjust your dr iving to road and traf­
f ic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks .
- Although the all-wheel drive is very ef­
fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfa ces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
co uld begin to slide on top of the water
(aquaplaning) . If this should occur, yo u
will have no warning from a s udden in ­
crease in engine speed as w ith a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions -risk of crash.

Snow chains
Snow chains may be fitted only to the front
wheels, and only to certain tire sizes. Ask your
authorized Audi dealer on which tire sizes
snow chains can be used.
The snow chains must have low-profile links
and must not be thicker than 0.53 inch
(13.5 mm), including the lock .
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
~ 0. For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
~ WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(j) Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to
vehicles with all wheel drive.
Tires and wheels 251
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is ma tched to the
factory inst alled rims. If diffe ren t 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
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 282 .
&_ WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control , a collision and serious personal 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 tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can become loose while driving if greased or
oiled, even if tightened to the specified
torque .
- Only use wheel bolts that belong to the
rim being installed .
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening 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 vehi­
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(I} Note
The specified torque for the wheel bolts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque wheel bolts .,.. •

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect
ratio t ires . These t ires have been thoroughly
tested and been selected spec ifica lly for your
model for the ir superb pe rformance, road feel
and handling under a va riety of driving condi­
tions . Ask your a utho rized Aud i dea le r for
more detai ls.
The low aspect ratio of these ti res is indicated
by a numeral of
55 or l ess in the tire's size
des ignation. The numera l represents the rat io
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
tional tires have a height/width ratio of 60 or more.
The performance of low-a spe ct-ratio ti re s is
p articu lar ly sensi tive to imprope r inflat ion
pressure. It i s therefore impo rt a nt th at low
aspect r atio tire s are inflated to th e specified
pr essure and tha t th e inflation pres sure is
regularly checked and maintain ed . Tire pr es­
s ure s should be checked at l east once a
m onth and alway s befor e a long trip
~ page 241, Checking tire pressure.
What you can do to avoid tire and rim
damag e
Low aspect ratio t ires can be damaged more
eas ily by impact with potho les, cu rbs, gu llies
or ridges on the road, part icu larly if the t ire is
underinflated .
I n o rder to m inim ize the o ccu rrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintai n recommended i nflat io n
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary . - Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immed iate ly inspect your
tires or have them inspected by the nearest
author ized Audi dealer. Replace a damaged
tire as soon as possible .
- Inspect your tires every 2,000 m iles (3,000
km) for damage and wear. Damage is not al­
ways easy to see . Damage can lead to loss of
air and under inflation, which could eventu­
ally cause tire failure.
If you believe that a
t ire may have been damaged, rep lace the
t ire as soon as possible.
- These tires may wear more quickly tha n oth­
ers.
- Please also remember that, while these tires
de live r responsive hand ling, they may ride
less comfo rtably and make more noise than
other choices .
Reduced performance in winter /cold
season c onditions
All tires are designed for certa in p urposes.
T he low aspect ratio, ult ra h igh performance
t ir es originally insta lled on your vehicle are in ­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy or icy weather conditions. If
you drive under those c ircumstances, you
shou ld equ ip your vehicle with all-season or
winter tires, which offe r bette r traction unde r
those conditions. We sugges t you use the rec­
ommended snow or all -se ason t ires specified
f or yo ur vehicle , or their equivalent.
