Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can also damage important pa rts of the
vehicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passenge rs a lso
depends on making s ure that load limi ts are
not exceeded . Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gross Veh icle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of f uel, oi l, coo lant and other fluids pl us
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger at a des ignated seat ing pos ition
and the tota l we ight of any l uggage in the ve­
h icle. If you tow a trailer, the weight o f the
trai ler hitch and the tong ue weight of the
loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weigh t Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Audi has 4 seati ng posi­
tions, 2 in the front and 2 in the rear for tota l
seating capacity of 4 . Each seating position
has a seat belt¢
page 129, Safety belts.
T he 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
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen­
gers in the vehicle or passengers who are
heavier than the 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 lists
the max imum combined weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For the location of the
label¢
page 226, fig. 185.
.&, WARNING ~ -
Overloading a vehicle can cause loss of ve ­
h icle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Ca rrying more weight than your vehicle
was des igned to carry wi ll prevent the
vehicle from handling properly 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 suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash .
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue we ight of a
loaded trailer - does not ma ke the vehi­
cle heavier than the vehicle's G ross Vehi­
cle Weight Rating.

A WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their" previous histo ­
ry ." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

Traction
The traction grades, from highest to lowest,
a re AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance¢ .&..
Temp eratu re
The temperature grades are A (the highest),
B, and
C, representing the tire 's resistance to
the generat ion of heat and its ability to dissi­
pate heat when tested under controlled condi­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failu re ¢ .&. .
The grade C corresponds to a level of perform­
ance which all passenger car tires m ust meet
u nder the Federa l Motor Ve hicle Safety Stand­
ard No. 109. Grades Band A represent higher
l eve ls of pe rformance on the laboratory test
wheel than the m inimum required by law.
_& WARNING
Th e traction grade assigned to this tire is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering , hydrop laning or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es ­
tablished for a t ire that is properly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possibl e tire fa ilu re.

Winter tires
Winter tires can improve vehicle handling on
snow and ice . At temperatures below 45 °F
(7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true w inter o r "snow" tir es, those
with very deeply cut t read. These tires should
o nl y be used in pairs and be installed o n all
f o ur wheels . Make sure you p urchase snow
ti res that are the same size and cons truc tion
type as the other tires on yo ur vehicle .
You r vehi cle is equipped wi th a ll w heel d rive,
th is w ill imp rove trac tion duri ng win ter driv­
ing, even with the standa rd tires. However, we
strong ly recommend that you always equip all
fo ur wheels on your vehicle with correctly fit­
ted winter tires or a ll-season tires, when win ­
ter road cond itions are expected. This also im­
proves the veh icle's brak ing performance and
reduces stopping d ista nces .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur whee ls .
As k your au thori zed A udi d ealer or qualified
workshop for permit ted
winter tire size s. Use
o nl y radial winter ti res .
Win ter tires lose their effec tiveness whe n the
tread is worn down to a dep th o f 0.15 7 inch
(4 mm) .
Only d rive w it h w inte r tir es under w inte r con­
di tions. S umme r tir es handle bette r whe n

The speed rating letter code( ¢ page 225) is
on the side wall of the tire¢ page
233.
A WARNING
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed . Always know the maximum
speed before driving off . Never drive faster
than the speed permitted for your specific
w inter t ires. This will cause damage to the
tires leading to an accident and serious
personal inj ury to you and your passen­
gers.
A WARNING
t"'----
Driving faster than the maximum speed
for which the winter tires on your vehicle
were designed can cause tire fai lure in­
cluding a blowout and sudden deflation,
loss of control, crashes and serious per­
sonal injuries. Have worn or damaged tires
replaced immed iately .
- Winter tires have maximum speed rat ing
that may be lower than your veh icle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your vehicle are rated.
A WARNING
Always adjust your d riving to the road and
traffic conditions. Neve r let the good ac­
celeration of the wi nte r t ir es and all whee l
drive temp t you in to taking extr a ris ks. A l­
ways remember :
- Whe n bra king, an a ll whee l drive vehicle
hand les in the same way as a front drive
vehicle.
- Drive caref ully and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp under black ice conditions.
@) For the sake of the environment
Use summe r ti res when weathe r cond i­
tions perm it. They are quieter, do not wea r
as quickly and red uce fue l consumption.
Snow chains
S now cha ins may be fitted only to the front
whee ls, and o nly to certain ti re sizes . Ask your
authorized Aud i dea ler on which tire sizes
snow chains can be used.
T he snow chains must have low-p rofile links
and mus t not be th icker than 0.41 inch
(10.5 mm), in cl ud ing the lock .
Remove whee l center covers and t rim discs
before putt ing snow chains on your veh icle
¢ Q) . For safety reasons cove r caps must then
be fitted over the wheel bo lts. These are avail ­
able from authorized Audi dealers .
_& WARNING
Using the wrong snow chains for your vehi­
cle or insta lling them incorrect ly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different sizes . Always make sure to follow the in­
structions prov ided by the snow chain
manufacturer .
- When driving with snow cha ins never
drive faster than the speed permitted for
your specific snow chains .
- Always observe local regulations.
(D Note
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessa rily.
- Snow chains, which come into direct con­
tact with the whee l rim, can scratch or
damage it . Therefore, make sure that the
snow chains are suitably covered. Check
the pos ition of the snow chains afte r
dr iving a few yards and co rrect if neces­
sary. Follow the instruct ions from the
snow chain man ufactu rer when doing so .
(D Tips
Where snow chains are ma nda tory on cer­
tain roads, th is normally also applies to
vehicles with a ll whee l drive .

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 differen t rims are fit­
ted, the correct wheel bolts with the right l ength and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -eve n if it
i s the same model
¢ page 266.
_&. WARNING
Improperly tig htened or maintained whee l
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
whee l 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 wh ile driving if greased or
o iled, even if tightened to the specif ied
torque .
- Only use wheel bolts that belong to the
rim being installed.
- Never use different whee ls bolts on your
vehicle .
-Always maintain the correct tighten ing
torque for the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor ­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cl e is moving.
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
Q;) Note
The spec ified torque fo r the wheel bo lts is
90 ft lbs. (120 Nm) with a tolerance of
± 7,4 ft lbs.(± 10 Nm). Torque wheel bo lts

torque m ust be checked as soon as possi­
ble with a torque wrench -preferably by an
a uthori zed Audi dea ler or qualified work­
shop.
Low aspect ratio tires
Your Aud i is factory -equ ipped w ith low aspect
ratio tires . These tires have been tho roughly
tested and been se lected specifically fo r your
model for their superb perfo rmance, road fee l
and hand ling under a var iety o f driving cond i­
tions. Ask your authorized Audi dealer for
more details .
T he low aspect ratio of these t ires is ind icated
by a numeral of
55 or l ess in the tire's s ize
designation. The numera l rep resents the ra tio
of the tire's sidewa ll height in relation to its
tread width expressed in percentage . Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
T he performance of low-a spe ct- ra tio tire s is
p ar tic ul ar ly se nsi tiv e to i mprop er i nfl ation
pre ssure. It is the refo re important that low
a spect ratio t ires are inflated to the specified
pr ess ure and that th e inflation pr essur e is
r e gula rly ch ecked and maintain ed. Tir e pre s­
s ure s should b e check ed at l east once a
m onth and alwa ys befo re a long trip
¢ page 228, Checking tire pressure.
What you c an do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, g ull ies
o r ridges on the road, pa rticularly if the tire is
u nderinflated.
In orde r to minimize the occurrence of impact
damage to the tires of your vehicle, we recom ­
mend that you observe the following p reca u­
tions:

Tire repair
General and safety pointers
Tire repair is intended only for temporary,
short-term use.
F ig . 1 9 2 Tire damage fo r wh ich the Tire Mob ility Sys­
tem is not suited
Your vehicle is equipped with a tire repa ir k it,
the
Tir e Mobility Sy stem (TMS ).
In the event of a tire failure, the TM S is in the
luggage compartment under the floor. It con­
s ists of the tire sealant and an electric air
pump .
Using
TM S, tire damage caused by foreign
bodies up to about
0.1 6 inch (4 mm ) in diam­
eter can be sea led reliably.
The foreign object must stay in the tire .
The tire sealant must not be used:
-for cu ts or punctures in t he tire w hich a re
large r th an 0. 16 inc h (4 mm) <=>fig. 192
©
-for damage to the rim @
- if you have been driving with very low t ire
pressu res or tires with no air@
Using the
TMS is descr ibed in the section
<=> page 244.

244 What do I do n ow ?
TMS can be used at temperatures down to
-4°F(-20°C).
.&_ WARNING
Take the following precautions after re­
pairing the tire:
- Do not d rive faster than 50 mph (80 km/
h)!
- Avoid full-throttle acce leration, heavy
braking and fast cornering.
- The veh icle's road behav ior can be affect­
ed.
- Tires sealed with
T M S are intended only
for
temporar y, short-te rm use . Dam­
aged tires must be replaced . Drive care­
fully to the next professional repair fa ­
cility.
- After using the tire sea lant the tire pres­
sure monitoring system may no longer
work properly. Drive carefully to the next
professional repair fac ility.
- TM S must NOT be used,
- for cuts or punctures in the tire which
are larger than 0.16 inch (4 mm)
- for damage to the r im
- if you have been dr iv ing with very low
tire pressures or t ires with no air
- Seek professional assistance if it is not
poss ible to repair the tire with the tire
sealant.
- The tire sealant must not come into con­
tact with sk in, eyes or clothing.
- If you get any tire sealant in your eyes or
com e into contact with i t, rinse the af­
fected area tho roughly w ith clean wate r.
Find a physician immediate ly!
- Change any clothing contaminated w ith
t ire sealant immed iate ly.
- Do not inhale t he vapo r!
- If you have swallowed t ire sealant , rinse
yo ur mouth thorough ly r ight away and
dr ink p lenty of water.
- Do not induce vomiting! Find a physi ­
cian immediate ly!
- If you have a llergic reactions, f ind a
physician immediate ly.
- Keep the t ire sealant away from chi ldren.
(D Note
Do not use commercially avai lab le tire
sea lants. The electr ica l components of the
tire pressure monitoring system will no
l onger work properly.

Inflating a tir e
~ Screw the filling hose for the electric a ir
pump onto the tire valve and insert the con­

~ Inflate the t ire between 2.0 and 2.5 bar and
read the pressure from the gauge.
~ If this tire pressure is not reached, drive
your vehicle approximate ly 10 meters for ­
ward or backwa rd so that the sealant can be
redistributed i nside the tire . If at th is time
the req uired air p ressu re still cannot be
reached, the t ire is too badly damaged and
cannot be repa ired with the tire sea lant.
