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 because the vehicle will be ex
tremely low. If you do dr ive with snow
chains on while the vehicle is at this lev
el, the snow chains might severely dam
age the wheelhouse and other parts of
the veh icle.
(!) Tips
Where snow cha ins are mandatory oncer
tain roads, this normally also applies to
veh icles with all-whee l dr ive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque .
The design of wheel bolts is matched to the
factory installed r ims. If different rims are fit
ted, the correct wheel bolts with the r ight
l ength and correctly shaped bolt heads must
be used. This ensures t hat wheels a re fitted
secure ly and that the brake system f unctions
correctly .
I n ce rtain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same mode l
<=?page 318.
.&_ WARNING
Improperly tightened o r maintained wheel
bolts can become loose ca using loss of
contro l, a co llision and serious persona l in
jury.
- Always keep the wheel 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 bo lts and
the threads in the wheel hubs. They can
become loose w hile driving if greased or
oiled, even if tightened to the specified
torque. -
On ly use wheel bolts that be long to the
rim being installed .
- Never use different wheels bolts on yo ur
veh icle.
- Always maintain the correct tightening
torque for the whee l bolts 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 tightening torque is
too high, the wheel bolts a nd threads
can be damaged and the whee l can be
come loose.
(D Note
The specified torque for the wheel bolts is 120 ft lb ( 160 Nm) with a to le rance of
± 7,4 ft lb( ± 10 Nm) . T orque wheel bolts
diagonally. After changi ng a wheel, the
torque m ust be che cked as soon as possi
ble with a to rque wrenc h - preferab ly by an
a uthorized Audi dea le r or q ualified work
shop.
Low aspect ratio tires
Your Audi is factory-equipped w ith low aspect
ratio tires. These tires have been tho roughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and hand ling under a variety of d riving condi
tions . As k your au thor ized A udi dealer for
more de tails .
T he low aspect ratio of these t ires is ind icated
by a numera l of
55 or l ess in the tire's s ize
designation. The n umeral rep resen ts the ratio
of the tire's s idewa ll height in relation to its
tread width exp ressed in percentage . Conven
t iona l tires have a he ight/width ratio of 60 or
more.
The performan ce of l ow-a spect-r atio tire s is
particularl y sen sitive to imp roper inflation

pressure and th at the inflation pressure is
regularly checked and mainta ined. Tire pres -

After changing a wheel
A wheel change is no t complete without do
ing the following .
"'Always store the vehicle tool kit, the jack
and the replaced ti re i n the luggage com
partment

"' Have the flat tire
replaced as soon as poss i
b le.
@ Tips
- I f yo u notice t hat the wheel bolts are
corroded and difficult to turn w hile
changing a t ire, they should be re p laced

Decorative wheel covers
App lies to vehicles: with decorative wheel covers
The decorative wheel covers must be removed
first to access the wheel bolts.

Notes on wheel changing
P lease read t he i nfo rmat ion c:> page 284, New
t ires and replacing tires and wheels
if y ou a r e
go ing to use a sp are tire w hich is different
from the ti res on yo ur vehicle.
After yo u cha nge a tire:
- Check the tire pressure on the spare imme
diately after installation .
- Have the wheel bolt tightening torque
che cked with a torque wrench as soon as
possible by your authorized Audi dealer or
a qualified workshop.
- With steel and alloy wheel rims, the wheel
bolts are correctly tightened at a torque of 120 ft lb (160 Nm) .
- If you notice that the wheel bolts are cor
roded and difficult to turn while changing
a tire, they should be replaced before you
check the tightening torque.
- Repla ce the flat tire with a new one and
have it installed on your vehicle as s oon as
possible. Remount the wheel cover.
Until then, drive with extra care and at re
duced speeds .
