chimes can be adjusted through the menu dis­
p lay
~ page 24 .
The range at which the sensors start to meas­
ure is
a b ou t:
To the side 2 feet (0.60 m)
Center rea r 5 feet (1.60 m)
Activation
The parking assist
is activated when r ev erse
ge ar is engaged . A b rief tone confi rms that
the system is activated .
Backing up
Distance warning when back ing up starts
when an obstacle is detected in the range of
the park assist system . As the d istance de­
creases, the time i nterva l between the audible
tones becomes shorter.
When the d istance is less than 1 foot (0.30
m), the tone becomes cont inuous . At this
poi nt you should stop backing up.
Please note that low objects already signalled
by a warning can disappear from the system 's
detection range and w ill not continue to be
signalled.
Potenti al malfunction s
If a warning buz zer sounds for a few seconds
when the ignition is sw itched on, there is a
system malfunction w ith the acoustic park as­
sist . If the malfunction persists unti l the igni­
tion is switched off , there will be no acoustic
warn ing at the next attempt to activate the
system . Have the problem corrected.
There is no confirmation tone when reverse
gear is engaged if there is a system ma lfunc­
tion .
For the park ing ass ist to operate, the sensors
must be kept clean and free of ice.
_& WARNING
- Sensors have blind spots in which objects
cannot be detected . Pay special attention
to sma ll children and animals. They can- not a
lways be detected by the sensors -
danger of an accident!
- The parking assist cannot rep lace the
driver's attention. The driver alone is re­
sponsible for parking and similar driving maneuvers. Always watch where you are
driving.
(D Note
Low obstacles already signa lled by a warn­
i ng can d isappear from the system's detec­
tion range as they are approached and w ill
not continue to be signalled. Objects such
as barrier chains, trailer draw bars, th in
painted vertical poles, o r fences may not
be detected by the system - risk of dam­
age .
@ Tips
For the parking assist to operate, the sen­
sors must be kept clean and free of snow
and ice.

146 Intellig ent technolog y
-If the power steering system should fail,
or if the eng ine is not running (for exam­
ple, while being towed), yo u wi ll st ill be
able to steer the veh icle. However, more
effort will be requ ired to do so .
- If the power steering system is not func­
tioning properly, contact your authorized
Audi dealer immediately .
Driving with your
quattro
App lies to vehicles: with all-wheel drive
With all-wheel drive, all four wheels are driv­
en.
General information
W ith all-whee l drive , power is distributed to
a ll four wheels . This happens automa tica lly
depending on your dr iv ing sty le and the road
conditions at the time. See also ~
page 141.
The all-wheel drive concept is designed for
high engine powe r. You r vehicle is exception­
ally powerful and has ex ce ll ent dr iving charac ­
teristics bot h under normal driving conditions
and on snow and ice. Always read and fo llow
safety precautions ¢
.&..
Winter ti re s
When dr iving in the w inte r, your ve hicle w ith
a ll-wheel d rive has an advantage, even with
regular tires . In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tir es) for improv ed driveability and brak­
ing: these tires must be mounted on
a ll fo ur
wheels . See also ¢ page 195, Win ter tires.
Snow cha in s
Where tire chains are mandatory on certain roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 196, Snow
chains.
Replacing whe els /t ires
Vehicles wit h all-wheel drive mus t always
have tires of the same size . Also avoid tires
with different tread depths. For details see page
q page 191, New tires and replacing
tires and wheels .
Off-Road driving ?
Your Aud i does no t have enough g round clear­
ance to be used as an off-road vehicle. It is
therefore bes t to avoid rough tracks and un­
even terrain as much as possib le . Also refer to
¢ page 150 .
A WARNING
-Always ad just your dr iv ing 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 t raction . You
should therefore not d rive at excessive
speeds on icy or slippe ry road surfaces.
- On wet road surfaces, be careful not to
d rive too fast because the front whee ls
could begin to slide o n top of the water
(aquaplan ing). If th is should occur, yo u
will have no warning from a s udden in ­
crease in eng ine speed as wit h a front ­
wheel drive vehicle. Always drive at
speeds which are su ited to the road con­
d itions. -risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting the engine.
If a vehicle with a conventional energy system
is not driven for a long per iod of t ime, the bat­
te ry is discharged by idling cur rent consume rs
(e .g. immobili zer) . In cert ain circumstances it
can resu lt in the re being insufficient energy
available to start the eng ine.
Intelligent energy management in you r vehi­
cle h andles the dis trib ution of e lectr ica l ene r­
gy. Start ing ability is ma rkedly improved and
the life of the battery is extended . .,._

was manufactured . Please see q page 192,
Speed roting (letter code) for a listing of the
speed rat ing letter codes and the maximum
speed at wh ich the t ires can be driven .
The speed rating letter code( ¢ page
183) is
on the side wall of the tire ¢ page 191.
A WARNING
Winter tires have maximum speed limits
that may be lower t han your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inte r tires. This will cause damage to the
tires leading to an accident and serious
pe rsonal inj ury to you and your passen­
gers .
A WARNING
= ~
Driv ing faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
rep laced immed iate ly .
- Winter tires have maximum speed rat ing
that may be lower tha n your veh icle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d riving to the road and
t raffic conditions. Neve r let the good ac­
celeration of the wi nte r t ir es and all-whee l
dr ive temp t you in to taking extr a ris ks . A l­
ways remember :
- Whe n bra king, an al l-wheel d rive vehicle
hand les in the s ame way as a front drive
vehicle.
- Drive c aref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
{® For the sa ke of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be f itted only to the front
whee ls, and o nly to certain tire sizes . Ask your
autho rized Aud i deale r on which tire sizes
snow c hains ca n be used.
If you are go ing to use snow chains, then you
must i nstall them on the front whee ls at
least.
The snow chains must have low-prof ile links
and must not be t hicker than 0.53 inch
(13.5 mm), includ ing the lock .
Remove whee l center covers and trim discs
before putt ing snow cha ins on your vehicle
¢ \!) . For safety reasons cover caps must then
be fitted over the wheel bolts . These are ava il ­
able from autho rized Aud i deale rs .
A WARNING
Using the wrong snow chai ns for your veh i­
cle o r in stall ing them in correct ly can in­
crease the risk o f loss of cont ro l leading to
se rious personal injury.
- Snow chains are available in di fferent
sizes. Always make sure to follow the i n­
structions provided by the snow chain manufacturer .
- When driving wi th snow cha ins never
d rive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations .
(D Note
-Remove snow chain s before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessa rily.
- Snow chains, which come in to direc t con­
t act with the whee l rim, can scrat ch or
damage it . Therefore , make sure that the
1J1-

snow c hains are suitably cove red . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow cha in manufacturer when doing so.
Where snow cha ins 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 r ims . If different rims are fit­
ted, the correct wheel bo lts with the right
length and correctly shaped bolt heads must
be used. This ensures t hat wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
i s the same model
¢ page 227.
A WARNING
Imprope rly tig htened or maintained wh eel
bolts can become loose ca using loss of
con trol, a collision and serious person al in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be p rop ­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel hubs. They can become loose w hile driving if greased or
o iled, even if tig htened 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 maintai n the co rrect tig htening
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss. If the tightening tor-
Tire s an d wheel s 197
que of t he whee l bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tig htening torq ue is
too high, the wheel bolts and threads
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 tor que
must be checked as soon as possible with a
torq ue w rench -prefe rably by an au thor­
iz ed A udi de aler or qu alified workshop .
Low aspect ratio tires
Your Audi is factory -eq uipped 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 performance, road fee l
and handli ng under a var iety of driving condi­
tions . Ask your authorized Audi dealer for
more d etails.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the t ire's sidewa ll height in relation to its
t read width exp ressed in pe rce ntage. Conven­
t iona l tires have a he ight/w idth rat io of 60 or
more.
The performanc e of low-a spect-ratio tire s is
particularly sensitive to impr oper inflation
pre ssure .
It is therefore important that low
a spect ratio tire s are inflated to the specified
pres sure and that the inflation pressure is
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 186, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w it h potholes, curbs, gul lies ..,.

pressure label¢ page 184. Driving on a
significantly under-inflated tire causes the tire to overheat and can lead to tire
failure . Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability .
- The driver is responsible for mainta ining
the correct tire pressures. You must
check the tire pressures regularly.
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.
Your vehicle registration becomes inval id
if you use these tires when not permit­
ted. Damage to your vehicle or accidents
cou ld also resu lt.
- If you switch between standard and run­
flat tires, an authorized Audi dealer or
qualified workshop must reprogram the
control module .
@ Tips
-The tire pressure monitoring system may
stop working when there is an ESC mal ­
funct ion .
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identif ication on the
tire sidewall ¢
page 191. We recom­
mend using these tires.

Run-flat ti res
Introduction
Applies to vehicles: with Run -f lat tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the tires run-flat ca­
pability if tire pressure is lost .
We recommend that r un-flat tires on ly be
m ounted on vehicles that were orig inally
equipped with these special tires at t he facto­
ry and have a Tire Pressure Moni toring Sys­
tem .
Run-flat tires can be identified by the letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
norma l to run- flat tires, you must b uy the
special rims required for run-flat tires, and the
T ire Pressure Monitor ing System must be re­
programmed by an authorized Aud i dealer o r
other qualified worksho p .
What do run-fl at tires do?
These special tires have r un-flat capabilities
that help keep you moving if a t ire loses pres­
sure and goes flat . Under favorable conditions
ti res can be dr iven
at least 30 miles (50 km) ,
but you mus t not dr ive faster than 50 mph Ill-
