Cast (light) alloy wheels
Cast (light) alloy wheels require special care .
.,. Wash the wheels with a sponge or hose
brush every other week.
.,. For deep cleaning afterwards, use only a
ded icated
acid-fre e cast alloy wheel cleaner .
.,. Rub a coat of
liquid wa x onto the rims every
three month. Be su re to rea ch and treat all
pa rts of the rim.
T o preserve the decorative appea rance of the
cast alloy wheels, some special care is neces­ sa ry. In addi tion to road d irt and salt, brake
dust is a lso co rrosive . If left on fo r too long,
brake d ust can cause pitting.
U se only spec ia l
acid-free cleaners formulated
for alloy r ims. Safe produc ts a re ava ilab le at
your aut ho rized Aud i dea le r. Neve r leave the
cleaner on the rims longer than specified on
the labe l. If not rinsed off promptly, the acid
contained in some cleaners can attack the
threads on the wheel bolts.

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
personal 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 deflation,
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, an 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 rear
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.
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 loc k.
Remove wheel center covers and trim discs
before putt ing snow chains on your vehicle
¢ @ . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il­
able from autho rized Aud i deale rs.
A WARNING
Using the wrong snow chai ns for your veh i­
cle o r insta lling them inco rrect ly can in­
crease the risk of loss of cont ro l leading to
se rious pe rsonal injury.
- Snow chains are available in different
sizes. Always 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 direc t con ­
tact with the whee l rim, can scratch or
damage it . Therefo re, make sure that the
snow chains are s uitably 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.
- If the Adaptive Air Suspension* should
malfunction, do not mount or use snow
chains beca use 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.
(0 Tips
W here snow cha ins are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
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 cor rect wheel bolts wit h the right
lengt h and correctly s haped bolt heads must
be used. This ens ures t hat w heels a re fitted
secure ly an d that the brake system f unctions
correctly.
I n ce rtain circumstances, you may not use
wheel bo lts from a d ifferent vehicle -even if it
is the s ame mode l~
page 3 21.
& WARNING
Improperly tig htened or maintained whee l
bolts can become loose ca using loss of
cont ro l, a co llision and serious persona l in­
jury.
- Always keep the w heel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly t ightened.
- Never grease or oil the wheel bolts and the threads in the wheel hubs. They can
become loose w hile driving if greased or
o iled, even if tig hte ned to the specified
torq ue.
Tire s an d wheel s 2 91
-On ly use whee l bolts that be long to the
rim being installed.
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct t ightening
torque for the whee l bolts to reduce t he
risk o f a wheel loss. If the tightening tor­
que of t he wheel bolts is too low, they
can loosen and come out when t he vehi­
cle is mov ing.
If the tig hte ning torque 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
120
ft l b ( 160 Nm) with a to le rance of
± 7, 4
ft lb( ± 10 Nm). Torque w heel bo lts
d iagon ally . After changi ng a w heel, the
torque m ust be chec ke d as soon as poss i­
b le with a to rque wrench -preferab ly by an
a uthorized Audi dea ler or q ua lified work­
shop .
Low aspect ratio tires
Your Audi is factory-equ ipped with tow aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb perfo rmance, road feel
and handli ng under a var iety of drivi ng condi­
tions. As k your au thori zed A udi dealer for
more de tails.
The low asp ect ratio of these tires is ind icated
by a nu mera l of
55 or l ess in the tire's s ize
designation. The n ume ra l rep resen ts the ra tio
of the tire's sidew all height in rel ation to its
tread width exp ressed in percentage . Conven ­
tiona l tires have a he ight/width ratio of 60 or
more.
The performance of low-aspect-ratio tire s is
particularly sensitive to improper inflation
pre ssure. It is therefore important th at low
aspect ratio tires are inflated to the specified pressure and that the inflation pressure is
regularly checked and mainta ined. Tire pres-
sures should be checked at least once a .,..
