Wheel bolts
Wheel bolts must always be tightened to the correct
torque .
The design of wheel bo lts is matched to the factory installed rims . If
different rims are fitted, the correct wheel bolts with the right length
and correctly shaped bolt heads must be used. This ensures that
whee ls are fitted securely and that the brake system functions
correctly .
I n certain circumstances, you may not use wheel bolts from a
different vehicle -even if it is the same model~ page 318.
& WARNING
Improperl y tightened or maintained wheel bolt s can be come loose
c au sing lo ss of control , a co llis ion and seriou s personal injur y.
• Alwa ys keep the wheel bolt s and the th reads in the wheel hubs
c lean so the wheel bolt s can turn ea sily and be properl y tightened.
• Never gre ase or oil the wheel bolt s and the thre ad s i n the wheel
hub s. They can become lo ose while drivin g if gre ased or oiled ,
e ven if tig hten ed to th e specifi ed torque .
• Onl y use wheel bo lt s th at bel ong to the rim being in sta lled.
• Nev er use differ ent wheel s bolt s on your vehicle.
• Alway s m aintai n the corre ct t ightenin g to rq ue for the whee l
bo lt s to r edu ce the ri sk of a whe el los s. If the tighten ing torque of
t h e w heel bolt s is too l ow, they c an loose n a nd com e out when th e
v ehicl e is mov ing . If th e tighte ning torque is t oo high, the whe el
b ol ts an d threads can be dam ag ed and the whee l can become
loo se .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
tolerance of ± 7,4 ft lb(± 10 Nm). Torque whee l bolts diagonally.
After changing a wheel, the torque must be checked as soon as possible with a torque wrench
-preferably by an authorized Audi
dea ler or qua lified workshop .•
Low aspect ratio tires
Your Audi is fac tory-equipped with low aspect ratio tires. These tires
have been thorough ly tested and been selected specifically for your
model for their superb performance, road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated by a numera l of 55 or
l e ss in the tire's size designation . The numera l represents the ratio
of the tire's sidewa ll height in relat ion to its tread w idth expressed
in percentage. Conventiona l tires have a height/width ratio of 60 or
more .
T he perform ance of lo w-as pect-rati o tire s is part ic ul arl y s ensit ive to
improp er infla tion pr essure. It i s there fore important that low
a s pect ra tio tir es are inflated to the sp ec ified pre ssure an d th at th e
i nfl ation pre ssure is regularl y checked and m aintained . T ir e pres ­
s ure s should b e checked a t lea st once a month and alw ays before a
long trip~ page 274, "Checking tire pressure".
What you can d o to avoid tire a nd rim dama ge
Low aspect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the tire
is underinflated.
In order to minimize the occurrence of impact damage to the tires
of your vehic le, we recommend that you observe the fo llowing
precautions:
• Always maintain recommended inflation pressures . Check your
tire pressure every 2,000 miles (3,000 km) and add air if necessary .
• Drive careful ly on roads with potholes, deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your tires. Impact with a curb may also cause damage to
your tires . .,_

Wheel change
Before changing a wheel
Follow these points for your own and your passenger's
safety when replacing a wheel.
-After you experience a tire failure, pull the car well away
from moving traffic and try to reach level ground before
you stop => & .
- All passengers should leave the car and move to a safe
location (for instance, behind the guardrail)=>& .
- Apply the parking brake firmly=>&.
- Move selector lever to position Pon an automatic trans-
mission; put manual transmission in first gear =>& .
- If you are towing a trailer: unhitch the trailer from your
vehicle.
- Take the tool case and the spare tire=>
page 290 out of
the luggage compartment.
& 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 flasher 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 roadway 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. When one
front wheel is lifted off the ground, placing the Automatic Trans­
mission in "P" (Park), or engaging a gear in a manual transmission
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 spare wheel, make sure that you remount
the flat tire/wheel in its storage area properly and tighten the
knurled retaining screw securely. •
