A WARNING ~
To help avoid injury, be fo re you check any­
thing under the hood:
- Turn off the engine.
- Remove the ignition key.

256 Tire s and wheel s
-If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required .
(D Note
Driving without va lve stem caps can cause
damage to the t ire valves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the
valve .
@) For the sake of the environment
Underinf lated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not ha ndle
well a nd is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure , in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are not exceeded. Vehicle load includes everybody
a nd everyth ing in and on the vehicle . T hese
load limits are tech nica lly refe rred to as the
ve hicle 's
Gross V ehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory insta lled accesso ries, a full
tank of fuel, oi l, coo la nt and othe r fluids pl us
maximum load. The maxim um load includes
the number of passengers that t he vehi cle is
intended to carry ("seating capacity") w ith an
assumed weight o f 150 lbs (6 8 kg) for each
passenger at a designated seating pos ition
and the tota l weight of any l uggage in th e
ve­
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weig ht of the loaded tra
ile r must be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 5 seat ing
positions, 2 in the front and 3 in the rear fo r
total seat ing capac ity of 5. Each seating posi ­
t ion has a seat be lt
c:> page 149, Safety bel ts.
The fact that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
tra iler hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen ­
gers in the vehicle or passenge rs w ho are
heavier than th e standard we ights assumed
mea n tha t less we ight can be carried as lug­
gage .
T he t ire pressure label on your Aud i also lis ts
the max imum combi ned weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For t he lo ca tion of the
label <=>page 252, fig. 203.
A WARNING
Overloading a vehicle can cause loss of ve ­
hi cle cont ro l, a c rash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we ight than your veh icle
was des igned to carry wi ll prevent the
veh icle from handling pr operly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.
- Tires on a vehicle that has been overload­
ed can fail s uddenly, including a blowout
a nd sudden defla tion, causing loss of
contro l and a c rash .
~

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly 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 o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 297.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing 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 clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 265
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
105 ft lb (140 Nm) with a to lerance of
± 7,4 ft lb(± 10 Nm). Torque wheel bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop.
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 2 54, Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
