:E .. Push the release button ¢ fig. 269 and careful­
ly unscrew the cap to the left until you feel re­
sistance ¢,&. .
.. Push the release button again and remove the
cap completely .
.. Add coolant mixed in the correct ratio
¢page 328 up to the MAX marking .
.. Make sure that the fluid level remains stable .
Add more coolant if necessary .
.,. Turn the cap to the right to secure it until yo u
feel resistance a second time.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Aud i Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
A WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This increases the
risk of burns .
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ign ition is switched off, which
increases the risk of injury.
CD Note
Do not add coolant if the expansion tank is
empty. There may be air in the cooling sys­
tem, which increases the risk of engine dam­
age . If this is the case, do not continue driv­
ing . See an authorized Audi dealer or author­
ized Audi Service Facility for assistance.
Checking and Filling
Brake fluid

.. Read the brake fluid level on the brake fluid
reservoir ¢
page 324, fig . 267. The brake fluid
level must be between the MIN and MAX mark­
ings ¢,& .
The brake fluid level is monitored automatically.
Changing the brake fluid
Have the brake fluid changed regularly by an au­
thorized Audi dealer or authorized Audi Service Facility.
A WARNING
- If the brake flu id level is below the MIN
marking, it can impair the braking effect
and driving safety, wh ich increase the risk of
an accident. Do not continue dr iving. See an
authorized Audi dealer or authorized Audi
Serv ice Facility for assistance.
- If the brake fluid is old, bubbles may form
in the brake system dur ing heavy braking.
This would impair braking performance and
driving safety, which increases the risk of an
accident.
- To ensure the brake system functions cor­
rectly, only use brake fluids that comp ly
with VW standard 501 14 or FMVSS-116 DOT 4.

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility .
These facilities have the proper knowledge and are equipped with
the required tools and replace­
ment parts.
.,. New tires do not yet have the
optimum gripping properties. Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires .
.,. Use tires of the same construc­
tion, size (rolling circumference)
and as close to the same tread pattern as poss ible on all four
wheels .
340
.,.Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,. Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform
differently even if they are the
same size ¢
,&..
.,. If you would like to equip your
vehicle with a tire/rim combina ­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase ¢&, .
If the spare t ire is different from
the regular tires installed on the
vehicle -for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­
porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
On
all wheel drive vehicles, all
four wheels must be equipped
with tires that are the same brand and have the same construction
and tread pattern so tha t the
drive system is not damaged by .,.

Wheels
-Have an authorized Audi dealer or authorized Audi Service Facili­
ty check the wheel alignment if
there is unusual wear .
-Have the wheels rebalanced if an
imbalance is causing noticeable
vibration in the steering wheel. If you do not, the tires and other
vehicle components could wear more quickly.
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread
pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion¢
fig . 2 74 . The letters "TWI"
or triangles on the tire sidewall indicate the location of the tread­
wear indicators .
The tires have reached the mini­ mum tread depth
l) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones ¢
..&..
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
1> Obey any applicable regulations in your
country.
342
wear evenly. To rotate the tires,
install the tires from the rear axle
on the front axle and vice versa .
This will allow the tires to have
approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­
ing to the running direction indi­
cated on the tire sidewall
¢page 365.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are hidden . Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­
er or authorized Audi Service Fa­
cility to have the vehicle inspect­
ed .
.&_ WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety. ,..

:E: ' th e risk of an accident because it can cause
the tire t o burst.
- Always adapt yo ur drivi ng to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter tires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
die. symbol may be per­
m itted.
Snow chains
Snow chains no t only imp rove the driving in wi n·
t er roa d cond itions, but a lso the brak ing.
" Only insta ll snow chains o n the
front wheels .
" Check and cor rect the sea ting of the snow
chains after dr iv ing a few feet, if necess ary. Fo l­
low the ins truc tions from the ma nufa cturer .
" Note the maximum pe rmit ted speed w hen driv ­
ing with snow chains . Do not exce ed 30 mph
(SO km/h).
Use of snow chains is only pe rm itted with certain
rim/ti re combinations due to tec hnical reasons .
Chec k with an authorized A udi d ealer or author­
ized A udi Service F acili ty to see if yo u may use
snow chains.
Use
fine-mesh snow chain s. They must not add
mo re t han 0.53 in (13 .5 mm) in height , including
the chain lock .
You mus t remove the snow c hains on roads with ­
out snow . Otherw ise, you could impair dr iving
abi lity and damage the tir es .
Wh eel s
A WARNING
Using incorrect snow chains or install ing snow
cha ins incorrectly can resu lt in loss of veh icle
control, which increases the risk of a n acci­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con ­
t act with them . Remove the wheel covers*
first . Use coa ted snow cha ins .
- Do not install and use snow c hains if the re is

q page 149.
Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equipped with low -profi le tires* at
the factory . Compared to other tire/rim combina­
tions, low-prof ile tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls. This results in an agile dr iv ing style. How­
ever, it may reduce the level of comfort and in ­
c rease road noise when driving on roads in poo r
cond it ion.
Low-profile t ires can become damaged more
quickly than standard tires when dr iving over
la rge bumps, potholes , manhole covers, speed
bumps and curbs. Therefo re, it is particularly im­
po rtant to mainta in the co rrect ti re pressure
q poge 343.
To reduce the risk of damage to the tires and
r ims, drive very caref ully on poor roads.
Check your wheels regu larly every 2,000 mi
(3,000 km) for damage . For example, chec k for
bulges/cracks on the tires or deformations/
c racks on the rims . .,..
349

Wheels
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires.
Summer tires are not suitable for cold weather ,
snow or black ice. If you are driving in these con­
ditions, use winter or all season tires
¢ page 348.
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
¢ page 333, fig. 273.
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
(1 1/2) 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
350
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 ti re 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 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.

Run-flat tires
Introduction
Applies to: vehicles with run-flat tires
A run-flat tire helps to maintain vehicle mobility
when there is a loss of pressure.
Run-flat tires have reinforced sidewalls that pro­
tect the tire if there is a loss of pressure.
If the ti re pressure monitoring system indicates a
l oss of pressure in one or severa l ti res, you can
continue driving on run-flat tires fo r at least 20
miles (30 km). Drive to an authorized A udi dealer
or authorized Audi Serv ice Facility immediately to
have the problem corrected.
Continuing to d rive on run-flat tire s is no
longe r po ssible if
- there is visible damage to the tires, such as
cracks in the sidewalls .
- strong vibrat ions are felt wh ile driving, or the
tire beg ins to smoke due to a strong build-up of
heat .
- the t ire was heavily damaged, for example in an
accident There is a r isk that parts of the tire
tread will detach and damage important veh i­
cle components .
- the Electron ic Stabilization Contro l (ESC) is not
working or is cont inuously running .
