A WARNING ,~
- The cooling system is under pressure. Do
notopenthecapofthecoolantexpan
sion tank when the engine is hot . You
risk being scalded .
- The coolant additive, and therefore the coolant itself, is hazardous to health.
Keep the coolant additive in the original
container out of the reach of children. It
is a poison hazard.
(D Note
Do not add any type of radiator leak seal
ant to your vehicle's engine coolant. Add
ing radiator repair fluid may adversely af
fect the function and performance of your cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS ¢ &. in Working in the engine compart
ment on page 169.
.. Add coolant .
.. Twist the cap on again
tightly .
.. Tighten the cap (D ¢ page 176, fig . 144
again.
Replacement engine coolan t must conform to
exact specifications ¢
page 175, Coolant . If
the coolant additive G12+ + is not available in
an emergency, you must not add any other ad
ditive. In this case, use only water and restore
the correct mix ratio with the specified cool
ant additive as soon as possible.
Always use
new engine coolant when refilling .
Do not fill coolant above the "MAX" mark. Ex
cess coolant will be forced out through the pressure relief valve in the cap when the en
gine becomes hot .
With a major loss of coolant, you should add
the coolant only when the engine has
cooled.
In this way you prevent engine damage .
Checking and filling 177
A WARNING
-The cooling system is under pressure and
can get very hot . Reduce the risk of
scalding from hot coolant by following
these steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from escaping fluid and steam by covering
the cap with a large, thick rag.
- Turn the cap slowly and very carefully in a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being burned, do not spill an
tifreeze or coolant on the exhaust sys
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en
gine coolant can catch fire .
- Antifreeze is poisonous. Always store an
tifreeze in its original container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con
tainer clearly marked "poison".
Q) Note
-Coolant pollutes the environment and
could cause an engine fire. Excess cool
ant will be forced out through the pres
sure relief valve in the cap when the en
gine becomes hot.
- If, in an emergency, only water can be
added, the correct ratio between water
and antifreeze ¢
page 175 must be re
stored as soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Al
ways dispose of used coolant while observ
ing all environmental regulations.

We recommend that all work on tires and
wheels be perfo rmed by an authorized Audi
dea ler. They are familiar with recommended
proced ures and have the necessary spec ial
too ls and spare parts as well as the proper fa
cilities for disposing of the old tires.
Authorized Audi dealers have the necessary information about techn ica l requ irements for
installing or changing tires and r ims.
R eplacing t ire s and wheels
Tires sho uld be rep laced at least in pairs and
not individua lly (for examp le both front tires
or both rear tires together).
Be sure to read and heed the information to
the tire pressure monitoring system
¢page 195.
Always buy rep lacement radial tires that have
the same specifications as the tires approved
for your vehicle by Audi. Replacement t ires
must always have the same load rating speci
fication as the original equipment or approved
optional tires listed in the table¢
page 187.
Audi-approved specification ti res are specially
matched to your vehicle and its load limits,
and can contribute to the important road ho ld
ing, driving characteristics, and safety of the
vehicle. The table
(¢page 187) lists spec ifica
tions of the tires approved for the Audi mod

Uniform tire quality grading
- Tread wear
- Traction AA A B C
- T emperature ABC
Quality grades can be found where applicable
on the ti re side wa ll between tread shoulde r
and maximum section wid th ¢ page 193,
fig. 151 .
For example : Tread wear 200, Tract ion AA ,
Temperatu re A .
All passenger car tires must conform to Feder
al Safety Requi rements in addition to these
grad es.
Tread we ar
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a spec ified
government test course .
For example, a t ire graded 150 would wear
one and one half (1 1/2) t imes as well on the
government course as a tire graded 100 .
The relat ive perform a nee of ti res depends
upon the actua l conditions of their use, how
ever, and may depart sign ificantly from the
norm due to var iat ions in dr iv ing habits, serv
i ce practices and differences in road character
i stics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B and
C. Those grades represent the
tire's abil ity to stop on wet pavement as
measured unde r controlled cond it ions on
spec ified gove rnment test su rfaces of asphalt
and concrete . A tire ma rked C may h ave po or
t ra ction perfo rm ance¢ &..
Temp erature
The temperature grades are A (the h ighest),
B, and C, repr ese nting the t ire's resistance to
the gene rat io n of heat and its ab ility to dissi-
Tire s an d wheel s 197
pate heat when tested under controlled condi
tions on a specified indoor laboratory test
whee l.
Sustaine d high temperature can cause the
mater ia l of the tire to degenerate and red uce
tire life, and excessive tempe rat ure ca n lead
to s udden tire failure ¢ &. .
T he gr ade C correspon ds to a level of pe rform
ance which all passenger car tires must meet u nder the Federal Motor Vehicle Safety Stand
ard No . 109 . Grades Band A represent higher
l evels of performance on the laboratory test
whee l than the minimum requ ired by law.
A WARNING
The traction grade assigned to th is tire is
based on straight-ahead braking traction
tests, and does not include accele rat ion,
cor neri ng, hy droplaning or peak t ra ction
ch aracte rist ics.
A WARNING
T he temperature grade for this tire is es
tablishe d for a tire that is properly inf lated
and not overloaded . Excess ive speed, un
derinflation, or excessive loading, e it h er
separately or in combinat ion, can ca use
heat bui ldup 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 w inter or "snow" tires, those
with very deeply cut tread. T hese tires should
o nl y be used in pairs and be installed o n all
fou r wheels . Make sure you purchase snow

conditions. Ask your authorized Audi dea ler
for more details.
The low aspect ratio of these tires is indicated
by a numeral of 55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven
tional tires have a height/width ratio of 60 or
more.
The performance of low-aspect -ratio tires is
particularly sensitive to improper inflation
pressure. It is therefore important that low
aspect ratio tires are inflated to the specified
pressure and that the inflation pressure is reg
ularly checked and maintai ned. Tire pressures
should be checked at least once a month and
a lways befo re a long t rip
~ page 189, Check
ing tire pressure.
What you can do to avoid tire and rim
damage
L ow aspect ratio tires can be damaged more
eas ily by impact with potholes, curbs, gullies
o r ridge5 on the road, particu larly if the tire i5
underinflated.
I n order to minimize the occurrence of 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 air if neces
sary .
- Drive carefully 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
authori zed Aud i dealer. Rep lace a damaged
t ir e as soon as possible.
- Inspect your tires 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 underinflation, wh ich could eventu
ally cause t ire failure . If you believe that a tire
may have been damaged, rep lace the
tire as soon as possible.
- These tires may wear more quickly than oth
ers.
- Please also remember that, while these tires
delive r responsive handling, they may ride
less comfortably and make more noise than
other choices .
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
t ir es or iginally installed on your vehicle are in
tended for maximum dry and wet road per
formance and handling . T hey are not suitable
for cold, snowy or icy weather conditions . If
you drive under those c ircumstances, you
should equ ip your vehicle with winter tires,
which offer better traction under those condi
tions . We suggest yo u use the recommended
snow tires specified for your vehicle, or their
equivalent.
Refer to~
poge 197 for more detailed infor
mation regarding winter tires.
