-Tires and wheels
---------------------------------------------
It is important to ch eck the ti re pressure when the tires are cold .
• Read the req uire d tire p re s su re from the tire press ure la b el. On
USA vehicles, the tire p ressure label is located on the driver's side
8 -p illar. On Canada vehic les, the tire p ressure label is located either
on the driv er's sid e 8-pill ar or ins ide t he fuel fill er flap.
• Tur n the va lve stem cap c ounte r-cl ockwise to rem ove it fr om t he
tire valv e.
• Place th e a ir p re s sur e ga uge on th e valve .
• Th e tire pressures should only be checked and adjusted when
th e tires are col d. The s lig htly raise d pres sures of wa rm tires m ust
not be r educ ed .
• Adjus t the tire pre ssu re to the l oad you are carrying.
• Reinstal l the valve stem cap on the valve.

When should I adjust the tire pressures?
Adjust the tire pr essure to the load you are carrying . After changing
a whee l or re plac ing w hee ls you have to adj ust th e tire pre ssu res on

& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure, loss of control, collision , serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster, stop and inspect the tires .
& WARNING (continued)
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure , including a blowout and sudden deflation,
causing loss of vehicle control .
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on
a sticker on the driver's side B-pillar or on the inside of the fuel
filler flap.
• Only when all tires on the vehicle are filled to the correct pres­
sure , the tire pressure monitoring system* can work corre ctly.
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure mon itoring system* .
• Always inflate tires to the recommended and correct tire pres ­
s ure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Excessive speed and /overloading can cause heat build-up ,
s udden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the tire pressure and add air as required. _..

Incorrect wheel alignment
Incorrect wheel alignment can cause excess ive tire wea r, im pairing
the safety of the vehic le. If tires show excessive wear, have the
whee l alignment c hecked by an au th o rize d Audi deale r or qualifie d
wo rkshop.
All Wheel Drive
Vehicles with quattro® must always have tires of the same size, c ons truc tion and tread type. F or details see
~ p age 275 .
& WARNING
Sudden tire failure can lead to los s of control, a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• 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 dam age , such as
grease, oil , gasoline and brake fluid aw ay from tires .
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds. Tires 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 history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of veh icle control. •

• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the va lve stem caps securely mounted. We
recommend using fac tory insta lled valve stem caps . Ask your autho­
rized Audi dealer to replace lost valve stem caps .
T he installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni ­
toring system *, and is not recommended (cord material info rmation
i n molded on the t ire sidewa ll).
A lways check your tire pressure monitoring system * indicator after
replac ing one or more tires on you r veh ic le . If t he tir e pressure
monitoring system * indicator f lashes, or is on, your system is not
wo rking pr ope rly. Your re place ment tire might be i nco m patible wit h
your tire pr essure monitoring system *, or some component of the
t ir e pr ess ure moni toring system * m ay be da maged.
& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to los s of control , collision
and serious personal injury .
• Alway s use tires , rims and wheel bolts that meet the specifica ­
tions of original fa ctory -installed tires or other combination s that
have been specifically approved by the vehi cle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tire s that a re more than 6 years old can
only be used in an emergency and then with special care and at
lo wer speeds .
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been dam aged
even though the damage cannot be seen that can lead to sudden
ti re failure and lo ss of vehicle control.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling cir cumference ) and the same tread pattern . Driving
& W ARNING (continued )
with different tires redu ces vehicle 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 dri ve with extra care . Refit the
normal road wheel as soon a s safely pos sible.
• Never drive faster than the ma ximum 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 , su dden tire failure ,
includ ing a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chni cal reasons it is not always po ssible 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 vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brake s can them to overheat , increa sing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle mu st have a cha ssi s designed
for run flat tires and a factory -installed tire pressure monitoring
s ystem* that indicates a lo ss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accident s. Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run fl at tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted.

• If the spare tire is different from the tires that you have mounted
o n your vehi cle (for e xample winter tires or wide profile tires), then
use the spare tire for a short period of time on ly and drive with extra
care . Replace the f lat tire with the tire matching the others on your
vehicle as soon as possible.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system* .
Otherwise the system will register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
0 Note
• When installing new tires, be careful not to damage the valves or
tire pressure monitoring system* sensors.
• Never drive without the va lve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
c£> For the sake of the environment
Dispose of old tires in accordance with the loca l requirements. •
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Qua lity grades can be found where applicable on the tire side wal l
between tread shoulder and maximum section width
=> page 338,
fig. 278.
For e xample: Tread wear 200 , Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require­
ments in addit ion to these grades.
Tread w ea r
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under contro lled conditions on a specified
government test course.
For example, a tire graded 150 wou ld wear one and one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upo n the actua l condi­
tions of their use, however, and may depart significantly from the
n orm due to variations in d riving habi ts, service practices and differ­
ences in road characteristics and climate.
Tra ction
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 contro lled conditions on specified government
t est surfaces of asphalt and concrete . A tire marked C may have
poor traction performance => & .
Temperature
The temperature grades are A (the highest), 8, and C, representing
the tire's resistance to the generation o f heat and its abi lity to dissi ­
pate heat when tested under control led conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the mater ial of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>&.
T he grade C corresponds to a leve l of performance which a ll
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A represent higher levels of
p er formance on the la b ora tory test whee l than t he mi nimum
required by law.

• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possib le .
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventua lly cause tire failure. If
you believe that a tire may have been damaged, replace the tire as soon as possible .
• These tires may wear more quickly than others.
• Please a lso remember that, whi le these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.

c ondi tio ns
All tires are designed for certain purposes. The low aspect ratio,
u ltra high performance tires originally ins tal led o n your vehicle are
intended for maximum dry and wet road performance and hand ling.
They are no t suitable for cold, snowy or icy weather conditions . If
you drive under those circumstances, you should equip your vehicle
with al l- season or winter tires, which offer better traction under
those conditions. We suggest you use the recommended snow or
a ll-season tires specified for your vehicle, or their equiva lent.

panel left: Content
Face cover
-Locate the fuse which belongs to the component which
failed.
Switch off the ignition and the electrical component
affected. -
Carefully pry the face cover off the instrument panel
using the ignition key or a screwdriver~ fig. 293.
- Remove the plastic clip@ from its retainer in the face
cover~ fig. 294, place it over the questionable fuse and
remove the fuse.
- Replace a blown fuse (recognizable by the melted metal
strip inside) with a fuse of the
same amperage.
The individual circuits are protected by fuses. The fuse panels with
the fuses are located on the left and right front faces of the instru­
ment panel behind a cover and in the left and right storage areas in
the luggage compartment.
There is a plastic clip@ in the cover on the left side of the instru ­
ment panel, which can be used to remove the fuses. The crank © is
used for emergency operation of the power roof*. You will also find
a label on both covers in the instrument panel with the fuse layout
© for the corresponding fuse panel.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire.
(D Note
• On no account should fuses be repaired (e.g. patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause of the repeated short circuit or overload located and fixed . .,_

Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must
first be removed before you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
•
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop-.,
