-Cleaning and protection
-----=---=----------------------------------------
(I] Tips
Keep silicone sprays off the windshield to avo id wipe r smear in ra in. •
Cast (light) alloy wheels
Cast (light) alloy wheels require special care.
- Wash the whee ls with a sponge or hose brush every o ther
wee k.
- For deep cleaning afterwards, use on ly a ded icated
acid­
free cast a lloy wheel c leaner .
- Rub a coat of
liquid wax onto the rim s every three m onth .
B e su re to re ach an d treat all part s o f the rim .
To preserve th e decorat ive ap pea rance of the cast a lloy whee ls, some
special care is necessary. In a ddition to road dirt and sa lt, brake dust
is a lso co rro sive . If left o n fo r to o long, brake dust ca n ca use pi tting.
Use only spec ial
acid -free clea ners formulated fo r a lloy r ims . Safe
pro duct s are available at your author iz ed Audi de aler. Neve r leave the
cleaner on t he rims longer than spec ified on t he label. If not rinsed
off promptly , the acid conta ined in some cleaners can attack t he
t hreads on the wheel bolts .
N ever use abrasive or metal po lish ing cleaning agents.
If the protec ­
t ive c oating ha s b een ch ipped, e.g. by k icked up ro ad dir t, touch it up
as soon as possible.
& WARNING
• Moisture and ice on brakes may affect braking efficiency
=> page 255, "General information ". Test the brakes carefully
each time you wash the vehicle.

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control , collis ion
and seriou s personal injury.
& WARNING (co ntinued )
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that have been specifically app roved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that a re more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
eventhoughthedamagecannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial tires of the same
type , size (rolling circumference) and the same tread pattern.
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle - for example with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
no rmal road wheel as soon as safely possible .
• Never drive faster than the maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Ove rloading tire s cause heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or underinflated.
• For technical rea sons it is not always possible to use wheels
from other vehicles- in some cases not even wheels from the same
vehicle model.
• If you install wheel trim discs on the veh icle wheels, make sure
that the air flow to the brakes is not blocked . Reduced airflow to
the brakes can them to overheat , increasing stopp ing distances
and causing a colli sion.

----------------
& WARNING
Always adjust your driving to the road and traffic condit ions.
Never let the good a cceleration of the winter tires and all-wheel
drive t empt you into tak ing e xtra ri sks. Always rememb er:
• When braking , an all-wheel drive vehicle handle s in the same
way as a front drive vehicl e.
• Drive carefully and reduce your speed on icy and slippery road s,
even winter tires cannot help under black ice condit ions.
c£> For the sake of the environment
Use summer tires when weather co ndit ions permit. They are qu ieter,
do not wea r as qu ickly and r educe fuel consumpt ion. •
Snow chains
Snow c hains m ay be fi tted on ly to the rear w heels, and only to cer tain
tire sizes . Ask your authorized Audi dea ler on wh ich tire sizes snow
c hains can be used .
Th e snow chains must have low-profile links and m ust not be thicker
than 0.53 inch ( 13 .S mm), including the lock .
Remove wheel ce nter covers and trim discs before put ting snow
chains on your vehicle~
0. For safety reasons cover caps must then
be fi tted over t he wheel bolts . T hese a re av ail able fro m auth o rized
Audi dealers.
& WARNING
Using the wrong snow chains for your vehicle or installing them
in correctly can increa se the risk of loss of control leading to
serious personal injury.
Safety first
& WARNING (co ntinued )
• Snow chains are available in different sizes . Always make sure
to follow the instruction s provided by the snow chain manufac­
turer.
• When driving with snow cha ins never drive fa ster than the
speed permitted for your specific snow chains .
• Always observe local regulat ions.
0 Note
• Remove snow chains before driving on roads not covered wit h
snow to avoid damaging t ires and wear ing the snow chains down
unnecessar i Ly .
• Snow chains, whi ch come into direc t contac t wi th the w heel rim,
can scratch o r damage it. Therefore, make s ure that the snow chai ns
are sui tably covered. Chec k the pos ition of the snow chains after
dr iv ing a few yards and correct if necessary . Follow the instruct ions
from the snow chain ma nufact urer when do ing so.
• If the Adaptive Air Suspension* should malfunct io n, do not mount
or use snow chai ns because the ve hicle w ill be extreme ly low. If you
do d rive with snow chains on while the vehicle is at this level, the
snow c hains m ight severe ly damage the whee lhouse and other parts
of t he ve hicle .

Wheel bolts
Wheel bolts must al ways be tightened to the correct
torque .
The design of wheel bolts is matched to the factory installed rims. If
different r ims a re fitted, the cor rect wheel bolts with the r ig ht leng th
and correctly shaped bolt heads must be used. Th is ensures that
w heels are fitted secure ly and that t he br ake system func tion s
correctly .
In certain circ umstances, you may not use whee l bolts from a
different veh icle -even if it is the same model~
page 368.
&_ WARNING
Improperly tightened or maintained wheel bolts can become
loose causing lo ss of control , a c ollision and seriou s personal
injury .
• Always keep the wheel bol ts and the thread s in the wheel hub s
clean so the wheel bolts can turn easily and be properly t ighten ed .
• Never gr ease or oil the wheel bolt s and the threads in the wh eel
hubs. They can become loose while driving if greased or oiled, even
if tightened to the specified torque.
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle .
• Alway s maintain the correct tightening torque for the wheel
bolt s to reduce the risk of a whee l los s. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque i s too h igh, the wheel
bolts and threads can be damaged and the wheel can become
loose .
0 Note
The spe cifie d torq ue for the whee l bolts is 120 ft lb (160 Nm) wi th a
tolerance of ± 7,4 ft lb( ± 10 Nm). Torque whee l bolts diagona lly. After changing a wheel, the torq
ue m ust be checked as soo n as
possible wi th a t orqu e w rench -prefer ably by an auth o riz ed Audi
dealer or qualified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These tires
h ave bee n thorou ghly teste d and been se lec ted spe cifically fo r yo ur
model for their superb performance, road feel and hand ling u nder a
var iety of dr iving con ditions . Ask your authorized A udi dea le r for
more deta ils.
The low aspect ratio of these t ires is ind icated by a n umera l of
55 or
le ss
in t he tire 's s ize designation . T he numera l rep resents the ratio o f
the tire's sidewall he ight in relat ion to its tread width exp ressed in
pe rcen tage . Co nven tional ti res have a heig ht/w idth r atio o f 60 o r
more.
The performance of low-aspect-ratio tires i s particularly sensitive to
improper inflation pressure. It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pre ssure is regularly checked and maintained. Tire pre s­
sures should be checked at least once a month and always before a
long trip~
page 320, "Che cking t ire press ure".
What you can do to avoid tire and rim damage
Low aspe ct ratio tires ca n be damaged more eas ily by imp act wi th
potholes, curbs, gul lies or ridges on the road, part icu lar ly if the tire is
unde rinfl ated.
I n order to minimize the occu rrence of impact damage to the tires of
your vehicle, we recommend that yo u observe the follow ing p recau ­
tions:
• Always ma inta in recommen ded inflation p ressures. Check your
t ire press ure every 2,000 m iles (3,00 0 km) a nd a dd air i f ne cess ary.
• Drive ca ref ully on roads with potho les, dee p gullies or ridges. The
i m pact from d riving t hrough or over such obsta cles can damage you r
tires. Impact w it h a c urb may also cause damage to your tires . .,_

-Block the diagonally opposite wheel with the folding
chocks or other objects.
- Take the
jack and the inflatable spare tire out of the
luggage compartment =>
page 336.
& WARNING
You or your passengers could be injured while changing a wheel if
you do not follow these safety precautions:
• If you have a flat tire, move a safe distance off the road. Turn
off the engine, turn the emergency flashers on and use other
warning devices to alert other motorists.
• Make sure that passengers wait
in a safe place away from the
vehicle and well away from the road and traffic.
• To help prevent the vehicle from moving suddenly and possibly
slipping off the jack, always fully set the parking brake and block
the wheel diagonally opposite the wheel being changed with the
folding chocks or other objects. When one front wheel is lifted off
the ground, placing the Automatic Transmission in "P" (Park) will
not prevent the vehicle from moving.
• Before you change a wheel, be sure the ground is level and
firm. If necessary, use a sturdy board under the jack.
• After installing the inflatable spare tire, make sure that you
replace the flat tire/wheel in its storage area properly and tighten
the knurled retaining screw securely. •

[I] Tips
• When mounting tires with unid irectional tr ead design make sure
the tread pattern is po inted the r ight way ~
page 344.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the whee l and the h ub.
Remove all dirt from these surfaces before remounting the w heel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed in the righ t direction .
Using a spare tire w ith a t read pattern intended for
u se in a specific direction
When usi ng a spare tire w ith a t read pa ttern intended fo r use in a
specific direction, please note the following:
• T he di rec tion of rotation is ma rked by an ar row on the s ide of the
tire.
• If the spare tire has to be installed in the incor rect d irect io n, use
the spare tire only temporar ily since the tire will not be ab le to
a chieve its optim um pe rfo rma nce characteristics with rega rd to
aquaplaning, no ise and wear. _,.
