Snow cha in s
Where t ire cha ins are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive ¢
page 212, Snow
chains .
Replacing wheels /t ir es
Vehicles with all-wheel drive must a lways
have tires of the same size. Also avoid t ires
with different tread depths. For details see
page ~
page 207, New tires and replacing
tires and wheels.
Off -Ro ad dri ving?
Your Aud i does not have enough ground clear­
ance to be used as an off -road veh icle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible . Also refer to
¢ page 160.
A WARNING
Always adjust your driving to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel dr ive tempt you into
taking extra r isks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should the refore not dr ive at excessive
speeds on icy or slippery road su rfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning) .
If this should occ ur, you
will have no warning from a sudden in ­
crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions. -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
tery is discharged by idling current consumers (e .g. immobilize r). In certa in circumstances it
can resu lt in the re be ing insufficient energy
available to start the engine.
Intelligent energy management in your vehi­
cl e handles the distribution of e lectr ica l ene r­
gy . Start ing ability is ma rkedly improved and
the life of the battery is extended .
Bas ica lly, energy management consists of
b att ery diag nosis, idlin g curre nt manage ­
m ent
and dynamic en erg y manag em ent .
Battery di agnosis
Battery diagnosis continuously determines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current state o f charge and the power of the battery .
Idling current managem ent
Idling current management reduces energy
consumption while the vehicle is standing .
With the ig nition sw itched off, it controls the
energy supply to the various electri ca l compo ­
nents. Da ta from ba ttery diagnos is is cons id ­
ered.
Depend ing on the batte ry's state of cha rge,
individual cons ume rs a re g radually turned off
to prevent excessive discharge of the battery
and th us maintain starting capability.
Dynamic energ y manag ement
While the vehicle is being driven, dynamic en­
ergy ma nagement distr ibutes the energy gen­
era ted accord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
that more electrical energy is not being used ..,.

was manufactured . Please see q page 208,
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
( c::> page 199) is
on the side wall of the tire
c::> page 207.
A WARNING
Winter tires have maximum speed limits
that may be lower than 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 inter t ires. 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
= ~
Driving 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 than 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
traffic 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 , a n a ll-wheel d rive vehicle
hand les in the same way as a front drive
vehicle.
- Drive caref 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 env ironment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumption.
Snow chains
Snow cha ins may be f itted only to the front
whee ls, and only to certain tire sizes . Ask your
autho rized Aud i dealer on which tire sizes
snow c hains ca n be used.
If you are go ing to use snow chains, then you
must install 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
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts . These are ava il ­
able from autho rized Aud i dealers .
A WARNING
Using the wrong snow chai ns for your veh i­
cle o r ins ta ll 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 different
sizes. Always make sure to follow the i n­
structions provided by the snow chain manufacturer .
- When driving with 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
tact with the whee l rim, can scratch 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 245.
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 d riving 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 213
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 202, 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 ..,.

216 Tires and wheels
Inflate the tire pressure to the proper
pressure as indicated on the vehicle's tire
pressure label¢
page 200. 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 maintaining
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 ind i­
cator may be delayed.
- Ask your authorized Audi dealer if run­
flat tires may be used on your vehicle .
Your vehicle registration becomes invalid
if you use these tires when not permit­
ted. Damage to your veh icle or accidents
could also result.
- 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
stops working when there is an ESC/ABS
malfunction.
- Using snow chains may result in a system
malfunction .
- The tire pressure monitoring system on
your Audi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall ¢
page 207. We recom­
mend using these tir es.

Run-flat tires
Introduction
Applies to vehicles: wit h Run-fla t tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the t ires r un-flat ca­
pabili ty if tire pressure is lost .
We recommend that run-flat tires o nly be
mounted on vehicles that were orig inally
equipped with these special t ires at the facto­
ry an d have a Tire Pressu re Monitoring Sys­
tem .
Run-flat tir es can be identifi ed by th e letters
"RSC" on the tire sidewall.
If you do change the tires on your veh icle from
no rma l to run-flat tires, you must buy the
special rims required fo r run-flat tires, and the
T ire Pressu re M on itor ing System must be re­
programmed by an authorized Aud i d ealer o r
othe r qualified wo rkshop .
What do run -flat tires do?
These special tir es have run-flat capab ilities
that help keep you moving if a tire loses pres­
s ur e and goes flat. Under favorab le condi tions
t ir es can be dr iven
at least 30 miles (SO km) ,
but you mus t not drive fa ster than SO mph
( 80 km/h)
