Tire chain s
Where t ire cha ins are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll- wheel drive
c::> page 259, Snow
chains .
Replacing wheels /t ir es
Vehicles with all-whee l drive must a lways
have tires of the same size. Also avoid t ires
with different tread depths. For details see
page
c::> page 2 54, 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
c::> page206.
A WARNING
Always adjust your driving to road and traf­
fic condit ions. 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 w ater
(aquaplaning) .
If this should occ ur, you
wi ll 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 ha ndles 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 diagn osis, idlin g current 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 cu rrent and battery
tempe rature. This determines the current
state o f charge and the power of t he battery .
Idling current management
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 energy manag ement
While the vehicle is being d riven, dynamic en­
ergy ma nagement distr ibutes the energy gen­
era ted a ccord ing to t he needs of the individ u-
al components .
It regula tes consumption, so
t h at more electrical energy is not being used ..,.

The speed rating letter code (c::> page 246) is
on the side wall of the tire
c::> page 254.
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
winter tires . This will cause damage to the
tires leading to an accident and serious
personal injury 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 failure in­ cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
replaced immediately.
- Winter tires have maximum speed rating
that may be lower than your vehicle's
maximum speed .
- Never drive faster than the speed for
which the winter or other tires installed
on your vehicle are rated .
A WARNING
Always adjust your driving to the road and
traffic conditions. Never let the good ac­
celeration of the winter tires and all-wheel
drive tempt you into taking extra risks . Al­
ways remember :
- When braking, an all-wheel drive vehicle
handles in the same way as a front drive
vehicle.
- Drive carefully and reduce your speed on
icy and slippery roads, even winter tires
cannot help under black ice conditions.
@l For the sake of the environment
Use summer tires when weather condi­
tions permit. They are quieter, do not wear
as quickly and reduce fuel consumption.

Tires and wheels
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.
If you are going to use snow chains, then you
must install them on the front wheels at
least.
The snow chains must have low-profile links
and must not be thicker than 0.4 inch
(10,S mm) , including the lock.
Remove wheel center covers and trim discs
before putting snow chains on your vehicle
c::> (]) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are avail­
able from authorized Audi dealers.
A 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.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow ..,.

chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle.
(D} Tips
Where snow chains 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 installed r ims. If different 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
secure ly 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 mode l
¢page 287.
_& WARNING
Imprope rly tig htened o r maintained whee l
bolts can be come loose ca using loss of
contro l, a co llision and serious persona l in­
jury.
- Always keep the wheel bol ts an d the
threads in the wheel hubs clea n so the
wheel bolts can tu rn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the wheel h ubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle.
- Always maintain the correct tighten ing
torq ue for the wheel bo lts to reduce the risk of a whee
l loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing. If the tighte ning torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be­
come loose.
([) 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). Torque whee l bolts diago­
nally. Afte r changing a whee l, the torque
must be checked as soon as possible wi th a
torque wrench -pre ferably by an au thor­
ized Audi dealer or qualified workshop .
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling u nder a var iety of d riv ing condi ­
t ions . As k your author ized 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 rep resents the ratio
of the t ire's s idewa ll height in relation to its
t read width ex pressed in percentage. Conven­
t iona l tires have a he igh t/w idth rat io of 60 or
more.
The performanc e of low -a sp ec t-ratio tires i s
pa rticularly sensitive to improper inflation
pre ssure . It is therefore important that low
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure i s
regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always befo re a long trip
¢ page 249, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w ith potholes, curbs, gull ies .,..

A WARNING 1= •
-If the tire pressure indicator appears in
the instrument cluster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braking
maneuvers. Stop as soon as possible and
check the tires and their pressures . In­
flate the tire pressure to the proper pres ­
sure as indicated on the vehicle's tire
pressure label¢
page 247. Driving on a
signif icantly 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 abi lity .
- The driver is responsible for ma inta ining
the cor rect t ire pressures. You must
check the t ire pressures regularly.
- Under certain cond itions (such as a spor­
ty driving style, w inter condit ions or un­
paved roads), the pressure monitor ind i­
c ator may be de layed.
- Ask your author ized Audi dealer if run­
flat tires may be used on your veh icle.

Using the spare tire (compact spare tir e)
The compact spare tire is only intended for
emergenc ies until you can reach a repair shop.
Replace it as quick ly as poss ible with a stand­
ard wheel and t ire.
There are some restrict ions on the use of the
compact spare t ire. The compact spare t ire
h as been des igned specifically for you r type of
veh icle. It must not be swapped wi th a com­
pact spare tire from another type of vehicle .
Snow chains
For technica l reasons, the use of snow chains
on the compact spare tire is
not p ermitt ed .
If you do have to dr ive with snow chains and a
front tire fails, mount the spare wheel w ith
tire instead of a rear t ire . Install the snow
What do I do now? 265
chains on the rear tire and use it to rep lace
the defective front tire .
A WARNING
-Never use the spare t ire if it is damaged
or if it is worn down to the tread wear in­
dicators.
- If the spare tire is more than 6 years old,
use it only in an emergency and with ex­
treme caution and careful driv ing.
- The spare tire is intended only for tem­
porary and short-term use . It should be
replaced as soon as poss ible with the
normal wheel and tire .
- After mounting the compact spare t ire,
the t ire pressure must be checked as
soon as possible . The tire pressure of the
compact spare t ire must be 4. 2 bar; oth­
erwise, you risk having an a ccident.
- Do not dr ive faster than SO mph (80 km/
h). You ris k having an accident .
- Avoid full-throttle acceleration, heavy
brak ing, and fast cornering. You risk hav­
ing an accident .
- Never drive using more than one spare
wheel and ti re. You r is k 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 spa re tire is not permitted .
If i t is necessary to d rive with t ire chains,
the spare wheel must be mounted on the
front ax le in the event of a flat in a rear
tire. The newly available front whee l
must then be insta lled in place of the
rear wheel w ith the flat tire. Installing
the t ire cha in before mounting the whee l
and tire is recommended .
- Loose items in the passenger compart­
ment can cause serious personal injury
during hard brak ing or in an accident.
Never store the inflatable spare tire or
jack and tools in the passenger compart­ ment. •
