A WARNING ,~
- The cooling system is under pressure and
can get very hot. Reduce the risk of scald ing
from hot coolant by following these steps.
- Turn
off the engine and allow it to coo l
down.
- Protect you r face, hands and arms from
escaping fluid and steam by cover ing the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in a
counter-clockwise d irection while applying
light, downward p ressure on the top of
the cap.
- To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in cond i­
tions, the ethylene glycol in eng ine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its orig inal container and well out
of the reach of children.
- If you dra in the coolant, it must be caught
and safely stored in a proper conta iner
clearly marked "poison".
- Do not add coolant if the expansion tank is
empty. Air cou ld enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving . Seek professional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire. Excess coolant will be
fo rced o ut through the pressure relief valve
i n the cap when the e ng ine be comes hot.
- If, in an emergency, only wate r can be add­
ed, the co rrect r atio betwee n wate r and an­
tifree ze
Q page 199 must be res to red as
soon as possib le.
{® For the sake of the environment
Dra ined coolant sho uld not be reused. Always
disp ose of used coolant while obse rving all
env ironment al regulat ions.

Rad iator fan
The radiator fan switches on automatically by it­
self .
The radiator fan is driven by the engine via the V­
belt. The viscous clutch regulates th e speed of
the fan accord ing to the temperature of the cool­
ant .
An auxiliary e lectr ic radiator fan* switches on and
off depending on coo lant temperature and other
vehicle operating conditions.
After you switch the engine
off, the auxiliary fan
can continue running for up to 10 m inutes -even
with the ignition
off. It can even switch on aga in
later by itself
Q .& , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­
gine compartment, or
- the engine compartment heats up beca use the
veh icle is parked in intense sunlight.
A WARNING
- To reduce the r isk of persona l injury neve r
touch the radia to r fan .
- The auxiliary e lectr ic fan is temperature
controlled and can switch on s uddenly even
when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on auto­
mat ically when the eng ine coolant reaches a
certa in temperature a nd will continue to run
until the coolant temperature d rops.

¢ page 219.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
gi vehicle and can lead to sudden ...... N
~ tire failure, including a blowout

and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­ sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gross Vehicle Weight Rat­
ing
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of..,.
219

Wheels
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 1 SO lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
220
driver's side B-pillar ¢ page 217,
fig. 180.
~ WARNING
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and
increase the risk of the 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 vehicle that has been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to­ tal load being transported -including the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.

Wheels
and a special procedure. You must not repair or
disassemble them¢&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct t ightening specifi ­
cation, see ¢
page 229, After changing a
wheel .
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim .
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Aud i
Service Facility . Never repair or disassemble
rims yourself, because this inc reases the risk
of an accident.
Winter tires
Winter tires s ignificantly improve the vehicle's
handling when driving in winter conditions . Be­
cause of their construction (width, compound,
tread pattern), summer tires provide l ess trac­
tion on ice and snow.
.,. Use winter tires on all four wheels.
.,. Only use winter tires that are approved for your
vehicle.
.,. Please note that the maximum permitted
speed may be lower with winter tires
q .&,. . An
authori zed Audi dealer or authori zed Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires .
.,. Check the tire pressure after install ing wheels
q page 217.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0 .157 inch (4 mm). The character istics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
- Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
222
-
the risk of an accident because it can cause
the tire to burst.
- Always adapt your driving to the road and
traffic conditions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter tires can lose traction on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumpt ion .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires w ith the ~ symbol may be per­
mitted.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.,. Check and correct the seating of the snow
chains if necessary after driving a few feet. Fol­
low the instructions from the manufacturer.
.,. Note the maximum permitted speed when dr iv­
ing with snow chains. Do not exceed 30 mph (SO km/h).
Snow cha ins not only improve the
driving in win­
ter road conditions, but also the
braking .
Use of snow chains is only permitted with certain
rim/tire combinat ions due to technical reasons .
Check with an author ized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0.53 inch (13.5 mm) in height, includ­
ing the chain lock.
You must remove the chains when driving on
roads that are
free of snow . When roads are free ..,.

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 207, fig. 178.
For example: Tread wear 200, Traction AA, Tem­
perature
A.
All passenger car tires must conform to Federal
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 gov ­
ernment test course.
For example, a tire graded 150 would wear one
and one half (11/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics 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 un­
der controlled conditions on specified govern­
ment test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance
¢ &. .
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce tire life,
and excessive temperature can lead to sudden
tire failure
c::> .&. .
224
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard
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, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING , ~ -
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat­
ed.
Tire pressure monitoring system
(l) General notes
App lies to : vehicles wit h tire pressure mo nitori ng syste m
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure for those tires) .
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant- ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and ""
