Safety belts
General notes
Always wear safety belts!
Wearing safety belts correctly saves lives!
This chapter explains why safety be lts are nec ­
essary, how they work and how to adjust and
wear them correctly .
.. Read a ll the information that fo llows and
heed all of the instruct ions and WARNINGS.
A WARNING
Not wearing safety belts or wearing them
improperly increases the risk of ser ious
personal in jury and death .
- Safety belts are the sing le most effective
means avai lab le to reduce the risk of se­
r ious injury and dea th in a utomob ile acci­
dents. For your protection and that of
yo ur passenge rs, always co rrectly wear
safety belts when the vehicle is moving.
- P regnant women, injured, or physically
im paired perso ns mu st also use safety
bel ts. Lik e all veh icle occup ants, they are
more like ly to be ser iously injured if they
do not wea r safety be lts . The best way to
protect a fetus is to protect the mother -
throughout the entire pregnancy.
Number of seats
Your Audi has a total of four seating positions: two in the front and two in the rear. Each seat­
ing position has a safety belt .
A WARNING
Not wearing safety belts or weari ng them
improp erly increases th e risk of ser ious
pe rsonal i njury and dea th.
- N ever st rap more than one pe rson, in­
cl uding small ch ild ren, into any belt.
It is
e speci ally dange rous to pla ce a safety
belt over a child s itting on yo ur lap.
- N ever le t mo re people ride in the ve hicl e
than there are s afe ty be lts avail able. -
Be s ure everyone riding in the vehicle is
properly restrained w ith a separate safe ­
ty belt or child restra int.
Safety belt warning light
Your vehicle hos o warning system for the
driver and (on USA models only) front seat
passenger to remind you about the impor­
tance of buckling-up .
Fi g. 130 Safety belt warni ng lig ht in the instrument
cluster -en larged
Before driving off, always :
.. Fasten you r safety belt and make sure you
are wearing it properly .
.. Make s ure that yo ur passengers a lso buck le
up and properly wear their safety be lts.
.. Protect your children w ith a child rest raint
system approp riate fo r the size and age of
t he children.
The . war ning light in the instrument cluster
lights up when the ignit ion is switched on as a
rem inder to faste n the safety belts. In addi­
t ion, you will hea r a warning tone for a certa in

Tires and wheels 235
Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle .
Fig . 17 6 Tir e pr essur e labe l: located on drive r's s ide B ·
p ill ar
Tire pressu re genera lly refers to the amount
of air in a t ire tha t it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna­
tional measuring unit and in pounds pe r
square inc h (PSI). Tire pressure is based in
p ar t o n the vehicle's desig n an d load limit­
the greatest amount of weight that the vehi­
cle can carry safe ly and the ti re size . The prop ­
er tire pressure is freq uent ly referred to as the
"recommended cold tire inf lation pressure ."
Air in the tires expands when the tire heats up
because of interna l frict io n when it flexes in
use . The ti re p ressu re is higher when the tire
has warmed up than when it is "cold ." It is the
i nflat io n pressure i n a "cold" tire that counts.
Therefo re, you s ho ul d never let air ou t of a
warm tire to matc h "cold tire infla tion p res­
sure" recommendations . The tires wo uld then
be underinf lated a nd could fail suddenly.
M ain taining proper t ire press ure is one of the
most impor tan t thi ngs you c an do to he lp
avoid sudden tire failure. Underinfla ted tires
are a major cause of s udden tire failure . Keep­
ing tires at the r ight pressure is also impor­
tant for safe and responsive vehicle handling,
traction, b rak ing and load carrying .
Tire pres­
sures are part icularly important wh en th e
vehicle is being driven at higher speeds , and
then especially when h eavily loaded even
within the permi ssible load -carrying capaci­
tie s approved for your vehi cle.

XL= reinforced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire side­
wall.
The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during the model year, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle with the
tires on your vehicle . Make sure that the tire
size information on the veh icle label is the
same as the size of the t ires on the vehicle .
This is especially important if the vehicle be­
lo ngs to someone else or you bought the veh i­
cle with different rims/tires o r you bought the
vehicle as a previously owned vehicle .
Remember, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle . These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat- ing
("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
G ross Axle Weight Rating are listed on the
safety comp liance sticker label located on the
drive r's side B-pillar . The tire pressure label on
your Audi lists the maximum combined
weight of all of the occupa nts and luggage or
other cargo that the vehicle can carry. For the
location of the tire pressure label¢
fig. 176.
A WARNING ._
Overloading a vehicle can cause loss of ve­
hicle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more weight than your vehicle
was designed to carry will prevent the
veh icle from handling properly and in­
crease the risk of a loss of vehicle con­
trol.

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.

Tir e pressure
Incorrect tire pressure causes premat ure wear
and can cause sudden tire blow-out . For th is
reason, tire pressure must be checked at least
once a month
r::!;> page 23 7.
Dri ving sty le
Driving fast around curves , heavy acceleration
and hard braking increase tire wear. Tires and wheels 241
Rotating tires for more even wear
For all four tires on your ve
hicl e to have the
same service life, we recomme nd that the
front and rear tires are rotated according to
the tire manufacturer 's suggested tire rota­
tion inte rvals. Please remember the follow ­
ing :
- Tire rotation intervals may differ from the
veh icle service inte rva ls o utlined in your
Ma intenance and Warranty Booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points ; therefore, we recommend that you
follow the tire manufactu rer 's suggested
tire rotation intervals .
- Vehicles w ith front-wheel dr ive exper ience
more tread wear on the front wheels com­
pared to all w heel drive (quattro ®).
- Please rotate tires as shown
r::!;> fig. 179.
-Extra care must be taken when rotat ing di-
rection-specific tires
r::!;> page 258 .
Wheel balancing
The wheels on new veh icles are balanced .
However, various situations during everyday
driving can cause them to become unba l­
anced, resulting in vibrat ions you can usually
feel through the steer ing wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, s uspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Inco rrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impair ing the safety of the vehi­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualified workshop.
All wheel drive
Vehicles wi th quattro ® must a lways have tires
of the same size, construction and tread type. For details see
r=> page 190 .

-All four wheels must be fitted with radial
tires of the same type, size (rolling cir­
cumference) and the same tread pattern .
Driving with different tires reduces vehi­
cle handling and can lead to a loss of
control.
- If the spare tire is not the same as the
tires that are mounted on the vehicle -
for example with winter tires -only use
the spare tire for a short period of time and drive with extra care. Refit the nor­
mal road wheel as soon as safely possi­
ble.
- Never drive faster than the maximum
speed for which the tires on your vehicle
are rated because tires that are driven
faster than their rated speed can fail
suddenly.
- Overloading tires cause heat build-up,
sudden tire failure, including a blowout
and sudden deflation and loss of control.
- Temperature grades apply to tires that
are properly inflated and not over or un­
derinflated .
- For technical reasons it is not always
possible to use wheels from other
vehicles -in some cases not even wheels
from the same vehicle model.
- If you install wheel trim discs on the ve­
hicle wheels, make sure that the air flow
to the brakes is not blocked. Reduced air­
flow to the brakes can them to overheat,
increasing stopping distances and caus­
ing a collision.
- Run flat tires may only be used on
vehicles that were equipped with them at the factory. The vehicle must have a
chassis designed for run flat tires and a
factory-installed tire pressure monitor­ ing system* that indicates a loss of tire
pressure. Incorrect use of run flat tires
can lead to vehicle damage or accidents.
Check with an authorized Audi dealer or
tire specialist to see if your vehicle can be
equipped with run flat tires .
If run flat
tires are used, they must be installed on
all four wheels. Mixing tire types is not
permitted.
Tires and wheels 245
@ Note
- For technical reasons, it is not generally
possible to use the wheel rims from oth­
er vehicles. This can hold true for wheels
of the same vehicle type.
- If the spare tire is different from the
tires that you have mounted on your ve­
hicle (for example winter tires or wide
profile tires), then use the spare tire for a
short period of time only and drive with
extra care. Replace the flat tire with the
tire matching the others on your vehicle
as soon as possible.
- Never drive without the valve stem cap .
The valves could get damaged.
(® For the sake of the environment
Dispose of old tires in accordance with the
local requirements.
Uniform tire quality grading
- Tread wear
- Traction AA A B C
- Temperature ABC
Quality grades can be found where applicable
on the tire side wall between tread shoulder
and maximum section width
c:> page 242,
fig. 180 .
For example: Tread wear 200, Traction AA,
Temperature A.
All passenger car tires must conform to Feder­
al Safety Requirements in addition to these
grades.
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course.
For example, a tire graded 1S0 would wear
one and one half (1 1/2) times as well on the
government course as a tire graded 100.

246 Tires and wheels
The relative performance of tires depends
upon the actual conditions of their use, how­
ever, and may depart significantly from the norm due to variations in driving habits, serv­
ice practices and differences in road character­
istics and climate.
Traction
The traction grades , from highest to lowest,
are 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 ¢.&, .
Temperature
The tempera ture grades are A (the highest),
B, and
C, representing the tire's resistance to
the generation 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 failure~.&, .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet under the Federal Motor Vehicle Safety Stand­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
A WARNING
The temperature grade for this tire is es­
tablished for a tire that is properly inflated
and not overloaded . Excessive speed, un­
derinflation, or excessive loading, either
-
separately or in combination, can cause heat buildup and possible tire failure.
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 winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your vehicle is equipped with all wheel drive,
this will improve traction during winter driv ­
ing, even with the standard tires. However, we
strongly recommend that you always equip all
four wheels on your vehicle with correctly fit­
ted winter tires or all-season tires, when win­
ter road conditions are expected. This also im­
proves the vehicle's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes . Use
only radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive with winter tires under winter con­
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °().
If you have a flat ti re, see notes on spare
wheel
¢page 242.
Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.

was manufacture d. Please see ¢ page 243,
Speed rating (letter code) for a listing of the
speed rat ing letter codes and t he maxim um
speed at whic h the tires can be driven .
The s peed rating letter code(¢
page 233) is
on the side wall of the tire
c::> page 242 .
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 inte r tir es . This will cause damag e to the
ti res leading to an ac cident and serious
pe rsonal in jury to you and yo ur passen­
gers .
A WARNING
Driv ing faster than the maximum speed
for which the winter tires on your vehicle
were designed can ca use tire fai lure in­
cl uding a blowout and sudden deflat ion,
loss of control, crashes and serious per­
sonal injuries . Have worn or damaged tires
rep laced immed iate ly.
- Winter tires have maximum speed rat ing
that may be lower tha n your veh icle's
maximum speed .
- Never drive faster than the speed for
w hich the winter or other tires installed
on your veh icle are rated .
A WARNING
Always adjust your d rivi ng to the road and
traffic conditions. Neve r let the good ac­
c eleration of the w inte r ti res and all whee l
drive temp t you in to taking extra r is k s . A l­
ways remember:
- When bra king, an a ll whee l dr ive vehicle
hand les in the s ame way as a front drive
vehicle.
- Drive carefu lly and reduce your speed on
icy and slippery roads, even winter tires
cannot he lp un der blac k ice conditions.

@) For the sake of the environment
Use summer tires when weather condi­
tions permit. They are qu ieter, do not wear
as quickly and reduce fuel consumpt ion.
Snow chains
Snow cha ins may be fitted only to the front
whee ls, and o nly to certain tire sizes . Ask your
autho rized Aud i deale r on which tire sizes
snow c ha ins can be used.
The snow chains must have low-prof ile links
and must not be t hicker than 0.53 inch
(13.5 mm) , includ ing the lock .
Remove wheel center covers and trim discs
before putt ing snow cha ins on your vehicle
c::> Q) . For safety reasons cover caps must then
be fitted over the wheel bolts. These are ava il­
able from autho riz ed Aud i dealers.
A WARNING
Using the wrong snow chai ns for your vehi­
cle o r insta lling them in co rr ect ly can in­
crease the risk of loss of cont ro l leading to
serious pe rsonal injury.
- Snow chains are available in different
sizes. A lways make sure to follow t he i n­
structions p rov ided by the snow chain
manufacturer.
- When driving with snow chains never
drive faster than the speed permitted for
your specif ic snow chains.
- Always observe local regulations .
(D Note
-Remove s now c hain s be fo re dr iv ing o n
roads not covered with snow to avoid
damaging tires and wea ring the snow
chains down unnecessa rily.
- Snow chains, which come into direc t con ­
tact with the whee l rim , can scratch or
damage it . Therefo re, make sure that the
snow chains are s uitably covered. Check
the pos ition of the snow chains after

In o rder to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom­ mend that you observe the following precau­
tions :
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add a ir if neces­
sary.
- Drive carefu lly 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 .
- After any impact, immediately inspect your
tires or have them inspected by the nearest
authorized Aud i dealer . Replace a damaged
t ire as soon as poss ible .
- In spect your t ires every 2,000 miles (3,000
km) for damage and wear . Damage is not al­
ways easy to see. Damage can lead to loss of
air and unde rinflation, wh ic h could eventu­
ally cause ti re fail ure.
If yo u be lieve that a
ti re may have been damaged , replace the
tire as soon as possible.
- These tires may wear more quick ly than oth ­
ers.
- Please a lso remembe r that, whi le these t ires
deliver respons ive handling, they may ride

All ti res are designed for certain purposes .
The low aspect ratio, ultra hig h performance
tires originally installed on your veh icle are in­
tended for max imum dry and wet road per­
formance and handling . They are not suitable
for cold, snowy or icy weather cond it ions . If
you dr ive under those circumstances, you
should equip your vehicle with all-season or
winter tires, whi ch offe r better traction under
those cond it ions . We suggest you use the rec­
ommended snow or all -season tires specified
for your ve hicle, or their equiva lent .

Tire pressure
monitoring system
ill General notes
App lies to vehicles : wi th tire p ress ure mo nito rin g system
Each tire, incl uding the spare (if provided),
shou ld be checked monthly when co ld and in ­
flated to the inflation pressure recommended
by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s iz e indicated on the vehicle placard or tire in­
flat io n pressu re labe l, you shou ld dete rmine
the p roper t ire inflation p ress ure fo r those
t i r es).
As an added safety feature, your veh icle has
been equipped with a tire pressure monitoring
system ( TPMS) that illum inates a low ti re
pressure te lltale whe n one or more o f your
ti res is significant ly under -inflated . According­
ly, when the low tire pressure te lltale i llumi­
nates, you shou ld stop and check your tires as
soon as possib le, and inflate them to the
proper pressure. Driving on a sign ificantly un­
der- inflated t ire causes the tire to overheat
and can lead to tire fa ilure . Under-inflation al­
so reduces fuel effic iency and tire tread life,
and may affect the vehicle 's hand ling and
stopp ing abil ity.
Please note that the TPMS is not a subst itute
fo r proper tire ma intenanc e, and it is the d riv­
er's respo nsibility to maintain co rrect tire
pressure, even if under-inflation has not
reached the leve l to tr igger illum inat ion of the
T PMS low ti re p ressu re tellta le .
You r vehicle has also been equipped with a
T PMS ma lf u nction indicator to ind icate w hen
the sys tem is not operating prope rly . T he
T PMS ma lfunction indicator is combined w ith
the low tire pressure te lltale. When the sys ­
tem detects a malfunction, the telltale wi ll
flash for approximate ly one min ute and then
rema in con tinuously i llum inated . T hi s se­
quence will continue upon subsequent vehicle
start-ups as long as the malfunct ion exists . ..,.
