Intelligent Technology
Driving with your
quattro
With all-wheel drive, all four wh eels are driven.
G eneral information
With all-whee l drive, power is distributed to all
four wheels. This happens automatically depend
ing on you r driv ing style and the road condit ions
at the time. See also¢
page 186 .
A center differentia l distrib utes the driving power
variably to the front and rear axle. It works to
gether with selective wheel torque control, which
activates when driving t hrough curves
~ page 186.
The all-wheel drive concept is designed for high
engine power. Your vehicle is exceptionally pow
erful and has excellent driving characterist ics
both under normal dr iv ing condit ions and on
snow and ice . Always read and fo llow safety pre
cautions ~

Winter tires
When driving in the winter, your vehicle with all
wheel drive has an advantage, even with regular tires. In winter road conditions it may be adv isa
b le to mount wi nte r tires (or all-season tires) for
improve d driveab ility and bra king: these tires
m ust be mounted on
all four wheel s. See also
¢ page 245, Winter tires.
Tire cha ins
Where tire chains are mandatory on certain
roads, this norma lly also applies to vehi cles w ith
all-whee l d rive ~
page 245, Snow chains.
Replacing wheels /tires
Veh icles with all-whee l dr ive must always have
tires of the same s ize. A lso avo id tires with d iffer
ent t read depths. For details see page
~ page 237, New tires or wheels.
.&, WARNING
Always adjust yo ur drivi ng to road and traff ic
c ondi tions . Do not let the extra safety afford
ed by all -wheel drive tempt you into ta king
extra risks .

-Although the all-wheel d rive is very e ffec
tive, always remember that braking capacity
is limited by tire tract ion. You shou ld there
fore not drive at excessive speeds on icy or
slippery road s urfaces.
- On wet road surfaces, be careful not to dr ive
too fast because the front wheels could be
gi n to slide on top of t he water (aquapla n
ing). If th is should occur, you will h ave no
warn ing from a s udden increase i n engine
spee d as wi th a front-wheel d rive vehicle.
Always d rive at speeds which are suited to
the road conditions -risk of crash.
Energy management
· Starting ability is optimized
Energy management controls the distribution of
electrical energy and thus optimizes the availa
bility of electrical energy for starting the engine .
If a vehicle with a conventional energy system is
not dr iven for a long period of time, the batte ry is
discharged by id ling current consumers (e.g. im
mobilizer) . In certain c ircumstances it can resu lt
i n the re being insuffic ient energy ava ilable to
start the eng ine.
Intelligent energy management in your vehicle
handles the d istribution of elec trical energy .
Start ing ability is markedly improved and the life
of the batte ry is ex tended.
Bas ically, energy management consists of
bat
tery diagnosis , idling current man agement
and
dynamic ene rgy management .
Battery diagnos is
Battery d iagnosis continuously determines the
state of the battery. Sensors determine battery
vo ltage , battery current and battery tempera
ture . This determines the current state o f charge
and the power of the battery .
Idling current management
Idling cur rent management reduces energy con
sumption while the vehicle is standing. With the ..,.

General information
.,. Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap proach the curb at an angle.
.,.Have faulty tires or rims re
placed immediately.
.,.Protect your tires from oil,
grease and fuel.
.,.Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled .
.,. Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D N ote
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons . Audi recom
mends using winter tires dur
ing the winter months . Low
temperatures significantly de crease the elasticity of summ
er tires, which affects traction
230
and b raking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi
tions. The surface of the rims
does not have sufficient corro
sion protection for this and
could be permanently dam
aged by road salt or similar
substances.

New tires or wheels
Audi recommends having all work on tires or wheels performed by
an author ized Audi dealer or au
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace
ment parts.
.,.New tires do not yet have the
optimum gripping properties. Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
.,.Use tires of the same construc
tion, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,.Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
Wheels
differently even if they are the
same size¢.&,. .
.,. If you would like to equip your
vehicle with a tire/rim combina
tion that is different from what
was installed at the factory, con
sult with an authorized Audi
dealer or authorized Audi Service
Facility before making a pur
chase¢ .&,..
The spare tire* is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
so only use the spare tire* tempo
rarily in case of emergency and
drive carefully while it is in use . It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by different tire speeds. For this rea
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires. .,.

and a special procedure. You must not repair or
disassemble them ¢.&. .
A WARNING
Wheel bolts that are tightened or repaired in
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi
cation, see ¢
page 2 56, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim .
- Always have damaged r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac
tion on ice and snow .
"'U se winter t ires on all fo ur wheels .
.. Only use winter t ires that are approve d for your
v ehicl e.
"' Please note that the maximum permitted
speed may be lower with winter tires¢.&_ . An
authorized Aud i dealer or au thori zed Aud i Serv
ice Fac ility can inform you about the maximum
permitted speed fo r your tires .
"' Check the tire press ure after installing wheels
¢page 240.
The effectiveness of winter tires is reduced great
l y when the tread is worn down to a depth of
0 .1 57 inch (4 mm). The character ist ics of winter
tires a lso de crease great ly as the tire ages, re
ga rdless of the remain ing tread.
WARNING
- Never drive faster than the maxim um per
mitted speed for your t ires. This cou ld cause
the tires to heat up too much. Th is increases
Wh eel s
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract io n on black ice.
@ For the sake of the environment
Reinsta ll summer tires at the app ropr iate
time, beca use they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fue l
consumpt io n.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, on ly
winter tires w ith the
& symbo l may be per
mitted .
Snow chains
Snow chains improve traction in the snow.
"'On ly install snow chains on the rear wheels.
"' Check and correct the seating of the snow
chains if necessary after d rivi ng a few feet. Fol
low the instructions from the manufacturer .
"' Note the maximum pe rmitted spe ed wh en dr iv
ing w it h snow cha ins. Do not excee d

Low aspect ratio tires
Your Audi is factory -equipped with low aspect ra
tio tires. These t ires have been tho roughly tested
a nd been se lected specifically fo r yo ur model fo r
thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s par
ticularly sensitive to improper inflation pres
sure . It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and always
before a long trip ¢
page 240.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, cu rbs, gullies or
246
ridges on the road, particularly if the tire is un
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom
mend that you observe the following preca u
tions:
- Always m aintain reco mmende d in fla tion pres
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i 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 always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.
Reduced performance in winter/cold season
conditions
A ll tires are des igned for certain purposes. The
l ow aspect ratio, ultra h igh performance tires
o rigin ally ins talle d on your veh icle are inten ded
for m aximum dry and wet road per forma nce and
handling . They a re not suitable for co ld, snowy or
