and is more difficult to stop. Overloading can not only lead to loss
of vehic le contro l, but can also damage important parts of the
vehic le and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash .
Your safety and that of your passengers also depends on making sure that load limits are not exceeded . Vehicle load includes every ­
body and everything in and on the veh icle . These load lim its are
technically referred to as the vehicle's
G ross Vehicle Weight R ating
("GVWR").
The "GVWR" includes the weight of the basic vehic le, all factory
installed accessories, a ful l tank of fuel, oil, coolant and other fluids
p lus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed we ight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
t he vehicle. If you tow a trai ler, the weight of the trailer hitch and the
tongue weight of the loaded trai ler must be included as part of the
vehic le load .
T he
G ros s Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehicle's two axles .
The Gross Vehicle Weight Rat ing and the Gross Axle Weight Rating
are listed on the safety compliance sticker labe l located either on
the d river's side B -pillar o r on t he inside of the f ue l fi ller flap. Yo ur
Audi has 4 seating positions, 2 in the front and 2 in the rear for total
seating capaci ty of 4. Each seating posi tion has a safety belt
=>
page 159, "Safety be lts" .
T he fact that there is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being carried in the vehicle (including the weight of a trailer hitch and the
tongue weigh t of the loaded trailer) is lim ite d. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure labe l on your Audi also lists the maximum
combined weight of a ll of the occupants and luggage or othe r cargo that the vehicle can carry
. For the location of the label=>

& WARNING
Overloading a vehicle can cau se lo ss of vehicle control , a cra sh or
other a ccident , seriou s personal injury , and even de ath .
• Carrying more weight th an your vehi cle w as designed to ca rry
will prevent the vehi cle from handling properly and in cre ase the
ri sk of the lo ss of vehicle control.
• The brakes on a veh icle th at ha s been overloaded ma y not be
able to stop the vehicle within a safe distance .
• Tire s on a vehicle that has been overloaded can fail suddenly,
i ncluding a blowout and sudden defla tion , cau sin g los s of control
and a crash .
• Alwa ys make sure that the tot al l oad be ing tran sported -
including the weight of a trai ler hit ch and the tongue weight of a
loaded trailer -does not m ake the vehicle heavie r than the
v ehicle 's Gro ss Vehicle Weight Rat ing .•

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 . .,_
