Cooling system
Coolant
The engine coo ling system is filled with a mixture
of purified water and coolant additive at the fac
tory. This coo lant must not be not changed.
The coolant leve l is monitored through
the . in
d icator
light ¢ page 28. However, we do recom
mend occasionally checking the coo lant level
manually.
I f you m ust add coolant, use a m ixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant addi tive is made of anti-freezing and
cor ros ion pro tection agents. Only use the follow
ing coolant additives . These additives may be
mixed with each other.
Coolant additive Specification
G13 TL 774 J
G12++ TL 774 G
The amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be operated .
If the coolant addi
tive percentage is too low, the coolan t can freeze
and damage the engine.

~ Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im
mediately drive your vehicle to an authorized
Audi dealer or authorized Audi 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.
.,&. WARNING
The cooling system is pressurized and can be
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
slowly and keep light pressure on the cap.
- To reduce the risk of burns, do not allow any
antifreeze or coolant to drip onto the ex
haust system or hot engine components.

The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- 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 ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving . See an authorized Audi deal
er or authorized Audi Service Facility for assis
tance.
- Before the start of winter, have an author
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en
gine. If this happens, only use water and re
store the correct mixture ratio with the
specified coolant additive as soon as possi
ble .
- Only refill with new coolant.
- Radiator sealant must not be mixed with the coolant.

New tires or wheels
Aud i recommends having all work on tires or
wheels performed by an authorized Audi dealer
or author ized Audi Se rvice Facility . These fac ili
ties have the proper know ledge and are equipped
with the required too ls and replacement parts.
• New tires do not yet have the optimum grip
ping properties. Drive caref ully and at moder
ate speeds for the first 350 mi les (500 km)
with new tires.
• Only use tires w it h the same design, size (roll
i ng c ircumference) and as close to the same
tread patter n as poss ible on all four wheels .
• Do not replace t ires individua lly. At least re
pla ce both t ires on the same axle at the same
t ime .
• Audi recommends that you use Aud i Original
Tires . If you wou ld like to use different tires,
please note that the tires may perform differ
ently even if they are the same
si ze ¢ ,& .
• If you would like to equip your veh icle w ith a
tire/rim comb inat ion that is different from
what was installed at the factory, consult w ith
an aut horized Aud i dea ler o r authorized Audi
Se rvice Facility befo re making a
purchase ¢,& .
The spare tire* is different from the regular tires
insta lled on the veh icle
-for example, if w inter

Applies to: vehicles with all wheel drive: all four
wheels must be eq uipped w ith tires that are the
same brand and have the same construc tion and
tread pattern so that the drive system is not
damaged by different wheel speeds. For this rea
son , in case of eme rgency, only use a spare tire*

that is the same circ umfe rence as the regular
tires.
A WARNING
--On ly use t ire/rim comb inations and suitab le
wheel bo lts that have been approved by
Aud i. Otherwise, damage to the vehicle and
a n accident could res ult.
-For technical reasons, it is not possible to
use t ires from other ve hicles
-in some cas
es, yo u cannot even use tires from the same
veh icle model.
-Make sure that the tires you select have
e nough clearance to the veh icle. Rep lace
ment tires should not be chosen s imply
based on the nomina l size, because ti res
wit h a differe nt constru ction can diffe r
g reatly even if they are the same size . If
there is no t enough clearance, the tires or

Low aspect ratio tires
Your Aud i is factory-equipped with low aspect ra
tio tires. These t ires have been thoroughly tested
and been selected specifically for you r model for
their superb performance, road feel and handling
under a va riety of driving conditions. As k your au
thorized Audi dealer for mo re de tails.
The low aspect ratio of these tires is indicated by
a numera l of
55 or less in the tire's size designa
tion . The numeral represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Conventional tires have
a height/w idth rat io of 60 or more .
The performance of low-aspect-ratio tires is par
ticularly sensitive to improper inflation pres
sure. It is therefore important that low aspect
ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should
Wheels
be checked at least once a month and always
before a long trip
¢ page 336 .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi
ly by impact w ith potholes, curbs, gullies or
ridges on the road, particularly if the tire is un
der inflated.
In order to minimize the occurrence o f impact
damage to the tires of your vehicle, we recom
mend that you observe the following precau
t ions:
-Always maintain recommended inflation pres
sures . Check your tire pressure every
2,000 miles (3,000 km) and add air if necessa
ry.
-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, immediate ly inspect your
tires or have them inspected by the nearest au
thorized Audi dealer . Replace a damaged tire as
soon as possible .
-Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not a lways
easy to see. Damage can lead to loss of air and
unde rinflation, w hich could even tually cause
t ire fa ilure.
If yo u bel ieve that a tire may have
been damaged, replace the tire as soon as pos
sible.
-These tires may wear more quickly than others.
-Please also remember that, while these tires
deliver responsive handlin g, 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 tires
origina lly installed on your vehicle are intended
for maximum dry and wet road performance and
handling. They are not suitable for cold, snowy or
icy weather conditions. If you drive under those
c ir cumstances, you should equip your vehicle
..,.
343
Wheels
with all-season or winter tires, which offer better
traction under those cond itions. We suggest you
use the recommended snow or all-season tires
specified for your vehicle, or their equivalent.
Refer to

tion regarding winter tires.
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 sect ion w idth
q page 328, fig. 278.
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 examp le, 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
marked C may have poor traction performance
q .,&..
Temperature
The temperature grades are A (the highest), B,
and C, representing the tire's resistance to the
344
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 ¢.&. .
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 tract ion 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 th is 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 bui ldup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat
ed .

Q page 346 . If the indicator light does
turn off or turns on again after a short period of
time, drive to an authorized Audi dealer or au
thorized Audi Service Facility immediately to have
the malfunction corrected.
A WARNING
- If the tire pressure indicator appears in the
instrument cluster display, reduce your
speed immediately and avoid any hard
steering or braking maneuvers. Stop as soon
as possible and check the tires and their
pressures.
- The driver is responsible for maintaining the correct tire pressures. You must check the
tire pressures regularly.
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
- Do not use run-flat tires on your vehicle. Us
ing them when not permitted can lead to
vehicle damage or accidents.
@ Tips
- The tire pressure monitoring system can al
