The best way to remove snow from windows and mirrors is to use a
brush . Use a non -abrasive
pla stic ice scraper -better still, a spray
deicer -to remove
ice from w indows and mirrors .
The windows must not be cleaned with insect remover or wax since
these can inter fere with the function of the w inds hie ld w iper blades
(chatter).
Oil, grease o r sil icone residue can be removed with
glass cleaner or
s ilicone remover . However, wax residue requires the use of a
spec ially fo rmulated so lvent . Please contac t your authorized Audi
dea ler for advice on safe products for wax removal.
Windows should also be c leaned on the inside at regular interva ls .
Never dry windows with the same chamois that you use to dry
painted surfaces . Wax residue on the chamois can impair vision
t hrough the windows .
& WARNING
• The windshield mu st not be treated with water -repellent mate ­
rials. T hey c an incre ase gl are under poor v isibility conditions such
a s wetne ss, darkne ss, or when the sun i s low on the hori zon. In
addition , they can cause the wind shield wipers to chatter .
• Alway s read and heed all WARNINGS and other information
~ page 206.
0 Note
• Never use warm or hot water to remove snow and ice from
windows a nd mirrors . This cou ld cause the glass to crack.
• T o prevent damage to the wires of the rear defogger, do not p lace
any adhesive stickers on the inside of the rear window over the
wires .
• T o he lp prevent dirt from scratching the window, always scrape
in a forward direction -pushing the scraper away from you -never
back and forth. •
Weatherstrips

- Rub a coat of
liquid wa x onto the rims every t hree month .
Be sure to reach and treat all parts of the rim.
To preserve the decorative appearance of the cast alloy wheels,
some special care is necessary. In addition to road dirt and salt, brake dust is also corrosive . If left on for too long, brake dust can
cause pitting.
Use on ly specia l acid -free cleaners formu lated for a lloy rims . Safe
products are available at your authorized Audi dealer. Never leave
the cleaner on the rims longer than specified on the label. If not rinsed off promptly, the acid contained in some cleaners can attack
t he threads on the wheel bolts. Never use abrasive or metal po
lishing cleaning agents . If the protec ­
t ive coating has been chipped, e.g . by kicked up road dirt, touch it
up as soon as possib le.

Tires
General notes
Tires may be the least appreciated and most abused parts
of a motor vehicle.
Tires may be the least appreciated and most abused parts of a
motor vehicle. Tires are, however, one of the most important parts
of a vehicle, particularly considering the comparative ly sma ll patch
of rubber on each tire that assures that all- important contact
between you, your vehicle and the road .
Maintaining the correct tire pressure, making sure that your vehicle
and its tires do not have to carry more weight than they can safely
handle, avoiding damage from road hazards and regu lar ly
inspecting tires for damage inc luding cuts , slashes irregular wear
and overa ll condition are the most important things that you can do
to help avoid sudden tire failure including tread separation and
b lowouts .
Avoiding dama ge
If you have to drive over a curb or similar obstacle, drive very slow ly
and as close as possible at a right angle to the curb.
A lways keep chemica ls includ ing grease, oil, gasoline and brake
f luid off the tires.
I nspec t the tires regularly for damage (cuts, cracks or blis ters, etc.l.
Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove them to indicate the direction of rota ­
tion . This ensu res you to be ab le to mount them correctly when you
reinstal l them. When removed, the wheels or tires shou
ld be stored in a coo l, dry
and preferably dark place.
St ore t ires in a vertical posit ion if they a re not mounted on rims, in
a horizontal position if they are mounted on rims.
New tire s
New tires have to be broken in~&.
The tread dep th of new tires may va ry, according to the type and
make of tire and the tread pattern.
Hidden d ama ge
Damage to tires and rims is often not readily visible. If you notice
unusua l vibration or the vehicle pul ls to one side, this may indicate
that one of the tires has been damaged . The tires must be checked
immed iately by an authorized Audi dealer or qualified workshop .
Unidire ction al tir es
A unidirectio nal tire can be iden tif ied by arrows on the s idewa ll, that
point in the direction the tire is designed to rotate. You must follow
the specified direction of ro tation . This is necessary so that these
tires can deve lop their optimum characteristics regarding grip, road
noise, wear and hydroplaning resistance . For more information
~ page 279.
in. WARNING
Ne w tire s or tire s that are old , worn or damaged cann ot pro vide
m aximum cont rol and braking ability.
• New tire s tend to be slippe ry and m ust be broken in . To redu ce
the risk of losing control, a colli sion and seriou s per sonal injurie s,
drive with speci al care for t he fi rst 350 m ile s ( 560 km l.
• Driving with worn or damaged t ire s can lead to lo ss of co ntrol ,

includes everybody and everything in and on the vehic le. These load
limits are technical ly referred to as the vehicle's Gross Vehicle
Weight Rating ( "GVWR"). The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two
a xl es . T he Gross Vehic le W eight Rat ing and the Gross A xle Weight

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident , serious personal injury, and even death .
• Carrying more weight than your vehicle wa s designed to carry
will prevent the vehicle from handl ing properly and increase the
ri sk of a loss of vehicle control .
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance .
• Tires on a vehi cle that has been overloaded can fail suddenly
cau sing loss of control and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi cle heavier than the
vehicle 's Gross Vehicle Weight Rating. _,.

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are specially matched to the char­ acteristics of the vehicle and can make a major contribution to good
road holding and safe handling when in good condition and prop ­
erly inflated =>& .
We recommend that al l work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special tools and spare parts as
we ll as the proper facilities for disposing of the old tires .
Authorized Audi dealers have the necessary information about tech ­
nical requirements for insta lling or changing tires and rims .
Rep lac ing t ires a nd w heels
Tires should be replaced at least in pairs and not individually (for
example both front tires or both rear tires together) .
Be sure to read and heed the tire pressure monitoring system*

& WARNING
• Using incorrect or unmatched tires and I or wheels or improper
tire and wheel combinations can lead to loss of control , collision
and serious personal injury .
• Always use tires , rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• 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 loss of vehicle control.
& WARNING (continued)
• All four wheels must be fitted with radial tires of the same type,
size (rolling circumference ) and the same tread pattern. Driving
with different tires reduces 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 e xample with winter tires - only use the spare
tire for a short period of time and drive with extra care . Refit the
normal road wheel as soon as safely possible.
• 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 underinflated .
• For te chnical 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 vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing 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 must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system * that indicates a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or t ire 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. .,

• For technical reasons, it is not genera lly possible to use the
whee l rims from other vehic les. This can hold true for wheels of the
same vehic le type.
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide p rofile t ires), then
use the spare tire for a short period of time only and drive with extra
care. Rep lace the flat tire with the tire matching the others on your
vehicle as soon as possible.
• If you put d ifferent wheels and tires on your veh ic le (e.g. w inter
whee ls and tires), you must be certain that the wheels and tires are
compatible with the tire p ressure monitor ing system*. Otherwise

• When insta lling new tires, be carefu l not to damage the va lves or
t ire p ressu re mon itoring system* sensors .
• Never drive without the va lve stem cap. The va lves could get
damaged.
• I f the sensors must be replaced, then the valve must also be
replaced at t he same t ime.
Dispose of o ld tires in accordance with the local requ irements .•
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 wall
b etween tread shoulder a nd maximu m section width =>
page 255,
fig. 184.
For example : Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federa l Safety Require ­
ments in addit ion to these grades.
T read wear
The tread wear grade is a comparative rating based on the wear rate
o f t he tire when tes ted under contro lled condit ions on a specified
government test course.
F o r example, a tire g raded 150 would 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 upon the actual condi ­
tions o f the ir use, however, and may depart sign ificantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characterist ics and c limate .
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 contro lled cond itions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor t raction performance =>& .
Temperature
The temperature grades are A (the highest), B, and C, represent ing
the tire 's resistance to the generation of heat and its ability to dissi ­
pat e heat when tested u nder con tro lled co nditions on a specified
indoor laboratory test wheel.
Sustained high tempera ture can cause the material of t he ti re to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>& .
The grade C corresp onds to a level of performance which all
passenger car tires must meet under the Federa l Motor Vehicle
