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 . .,_

Weights
G ross V ehicl e W eight R atin g
The Gross Vehic le Weight Rating (GVWR), and the Gross Axle Weigh t
Rating (GAWR) for front and rear are listed on a sticker on the left
door ja mb.
The Gross Vehicle Weight Rating includes the weight of the basic
vehicle pl us fu ll f uel tank, oil and coolant, plus maximum load,
wh ic h inc ludes passenger weight (150 lbs/68 kg per designated
seating position) and luggage weight.
Gross Axle We ight Rating
The Gross Axle Weight Rating is the maximum load that can be
app lied at each axle of the vehicle~ &.
Vehicle capacity weight
The vehicle capacity weigh t (max. load) is listed ei ther on the
driver's side B -p illar or inside the fuel filler flap .
& WARNING
• The actual Gro ss Axle Weight Rating at the front and rear axles
s h ould not e xceed the permi ssible weight s, and their comb in ation
mu st not exceed the Gro ss Vehicle Wei ght Rating.

ARNING (conti nued )
• Exceeding pe rmi ssible weight ratings can result in vehicle
d am age , ac ciden ts a nd per sonal inj ury .
0 Note
• The vehicle capacity weight figures apply when the load is
distributed even ly in the vehicle (passengers and luggage) . When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possib le so that the vehicle 's
handl ing is not impai red.
• Do not exceed the maximum permiss ib le axle loads or the
maximum gross vehicle weight . Always remember tha t the veh ic le's
handling wil l be affected by the extra load. Therefore, adjust your
speed according ly .
• Always observe local regulations. •
Dimensions
The specifications refer to the basic model. Differences may occur
depending on the mode l type and op tions o rdered, for example, tire
