rect ly as well. The parking system cannot
replace the driver's attent ion. The driver
is always respons ible for safety during
park ing and for all other maneuvers .
- Please note that some surfaces, such as
clothing, are not detected by the system .
- Sensors and cameras have blind spots in
wh ich people and objects cannot be de­
tected . Be especially cautious of children
and animals.
- The sensors can be displaced by impacts
or damage to the radiato r grille, bumper ,
wheel housing and the underbody . The
par king systems may become impaired
as a result. Have your authorized Audi
dealer or qualified workshop check their
function.
- Make su re the sensors are not covered by
stickers, deposits or any other obstruc­
tions as it may impair the sensor func­
tion . For information on cleaning, refer

Driving with your
quattro
Applies to veh icles: w ith all-w hee l d ri ve
With all-wheel drive, all four wheels are driv­
en.
General information
Wi th a ll-w heel d rive, power is dis trib ute d to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See a lso
¢ page 153.
The all -whee l dr ive concept is des igned for
high eng ine power. Your veh icle is except ion ­
ally powerfu l and has excellent d riving charac­
terist ics both under normal driving conditions
and on snow and ice. Always read and follow
safety precaut ions¢ .&..
Winter tires
When driving in the winter, yo ur vehicle with
all-wheel drive has an advantage, eve n wit h
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son tires) for improved driveability and brak­
ing: these tires must be mounted on
all four
wheel s.
See also ¢ page 210, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this norma lly also app lies to ve hicles

with all-wheel drive¢ page 211, Snow
chains .
Replacing wheels /tire s
Vehicles w ith all-wheel drive mus t always
h ave tires o f the same size. Also avoid t ires
with different tread depths. For details see
page
c::> page 206, New tires and replacing
tires and wheels.
A WARNING
Always adjust your driving to road and traf­
fic condit ions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel dr ive is very ef­
fective, always remember that braking capacity is limited by t ire traction . You
should therefore not dr ive at excess ive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
c ou ld beg in to s lide on top of the water
(aquaplaning). If this sho uld oc cur, 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 which 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 period of time , the bat­
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insufficient energy

Intelligent energy management in your veh i­
cle handles the d istribution of elec trical ener­
gy . Starting abi lity is markedly improved and
the life of the battery is extended .
Intellig ent technolog y 159
Basica lly, energy management consists of
b att ery diag nosis , id lin g cur rent man age­
ment
and dyn amic en ergy m anag ement.
Batte ry diagnosis
Battery diagnosis continuously determines
the state of the battery . Sensors determine
battery voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the batte ry .
Idlin g current manag ement
Id ling current management reduces energy
consumption while the vehicle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnosis is cons id­
ered.
Depending on the battery's state of charge ,
individual consumers are gradually turned off
to prevent excessive discharge of the batte ry
and thus maintain starting capability .
Dynamic energy manag ement
While the vehicle is being driven, dynamic en­
ergy management distributes the energy gen ­
erated according to the needs of the individ u­
al components . It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited.
- If start ing ability is threatened, the indi­
cator light (•) ;ippears

What you should know
The highest priority is given to maintaining
starting capability .

Speed rating (letter code) for a listing of the
speed rat ing letter codes and the maximum
speed at which the tires can be driven .
The speed rating letter code(¢
page 198) is
on the side wall of the tire
c::> page 206.
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 inte r tires . This will cause damage to the
tires leading to an ac cident and serious
pe rsonal inj ury to you and yo ur passen­
gers .
A WARNING
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use 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 veh icle are rated .
A WARNING
Always adjust your d rivi ng to the road and
traffic conditions. Neve r let the good ac­
c eleration of the w inte r ti res and all whee l
drive temp t you in to taking extra r is k s . A l­
ways remember:
- When bra king, an a ll whee l dr ive vehicle
hand les in the s ame way as a front drive

- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under blac k ice conditions.

@) For the sake 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 fitted only to the front
wheels, and o nly to certain tire sizes . Ask your
autho rized Aud i deale r on which tire sizes
snow cha ins can be used .
The snow chains must have low-prof ile links
and must not be th icker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel 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 vehi­
cle o r insta lling them incorrect ly can in­
crease the risk of loss of cont ro l leading to
serious personal injury.
- Snow chains are available in different
sizes. A lways make sure to follow the in­
structions p rov ided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove snow chains before dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains down unnecessarily.
- Snow chains, which come into direct con ­
tact with the whee l rim , can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the pos ition 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.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this normally also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled rims . If different rims are fit ­
ted, the correct wheel bolts with the right l ength 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 239.
.&_ WARNING
Improperly tig htened or maintained wheel
bolts can become loose ca using loss of
cont ro l, a co llision and serious p ersona l in­
Jury.
- Always keep the wheel bolts and the
threads in t he wheel hubs clea n so the
wheel bolts can tu rn easily and be prop­
erly tigh tened.
- N ever grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- O nly use wheel bo lts that be long to the
rim being installed.
- N ever use different whee ls bolts on your
vehicle.
- Alw ays mai nta in the co rrec t tighte ning
tor que fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the veh i- cle is moving.
If the tig
hte ning torq ue is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the whee l bolts is
105 ft lbs. (140 Nm) with a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changing a wheel, the
torque must be checked as soon as poss i­
ble with a to rque wrenc h - preferab ly by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is factory -eq uipped w it h low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details .
The low aspect ratio of these tires is ind icated
by a numeral of
55 or less in the tire's s ize
designation . The numeral represents the ratio
of the tire's sidewall height in relation to its
t read width exp ressed in percentage. Conven­
tiona 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
pa rticularly sen sitive to improp er inflation
pre ssure. It i s therefor e important that low
a spe ct ratio tir es are inflated to the spe cified
pre ssure and that the inflation pre ssure i s
regula rly checked and mainta ined. Tire pre s­
sure s should be checked at lea st once a
month and always befo re a long trip
¢ page 201, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gul lies
or ridges on the road, particularly if the tire is
underinflated . ..,.

-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 indi­
cator may be delayed.
- Ask your authorized dealer if run-flat
tires may be used on your vehicle. Your
vehicle registration becomes invalid if
you use these tires when not permitted .
Damage to your vehicle or accidents
could also result.
- The tire pressure monitoring system may
stop working when there is an ESC mal­

.. Remove the wing screw ¢
fig. 161 and take
out the retainer underneath .
.. Remove the bass box* ¢
page 217.
.. Take out the spare tire.
Snow cha in s
For technica l reasons, snow chains must not
be used on the spare tire .
Should you have a flat tire on one of the front
wheels when using snow chains, fit the spare
tire in place of one o f the rear whee ls. You can
then attach the snow chains to the whee l tak­
en from the rear and use this wheel to replace
the flat front twheel.
A WARNING
- Never use the spare tire if it is damaged
or if it is worn down to the tread wear in­
dicato rs .
- If the spare tire is more than 6 years o ld,
use it only in an emergency and w ith ex­
t reme caution and careful d riving .
- The spare tire is intended only for tem­
porary and short-term use. It should be
replaced as soon as possib le w ith the
normal wheel and t ire.
- After mounting the compact spare tire,
the tire pressu re must be checke d as
soon as poss ible. The tire pressure of the
c om pac t spa re tire must be 4.2 bar; oth­
erwise, you risk hav ing an accident .
- Do not drive faster than 50 mph (8 0 km/
h). You risk having an acc iden t.
- Avoid full-throttle acce le rat ion, heavy
braking, and fast corner ing . Yo u r isk hav­
ing an ac ciden t. -
Never drive using more than one spare
wheel and tire. You r isk having an acci­
dent.
- Normal summer or winter t ires must not
be mounted on the compact spare wheel
rim.
- For technical reasons, the use of tire
chains on the spare tire is not permitted.
If it is necessary to drive with tire chains,
the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The new ly available front wheel
m ust then be installed in place of the
rea r whee l w ith the flat tire. Installing
the tire chain be fore mounting the whee l
and tire is recommended.
- Loose items in the passenger compart ­
ment can cause se rious personal injury
during hard braking or in an accident. Never store the spare tire or jack and
too ls in t he passenger compartment.
