Checking and filling -
---------------------=----"=---------
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coolant additive to 60%.
• When adding coolant additive to your cooling system,
remember:
-We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant additive is available at autho­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection . The resulting corrosion can cause a
loss of coolant and serious engine damage .
• Do not add any type of radiator leak sealant to your vehicle's
engine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and cou ld result
in damage not covered by your New Vehicle Limited Warranty .•
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance.
Fig . 169 Engine
compartment : coolant
expansion tank
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 224.
Turn off the ignition .
Read the engine coolant level from the coolant expan­
sion tank==> fig. 169. With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
" max" marking .
The location of the coolant expansion tank can be seen in the
engine compartment illustration=>
page 225.
To obtain an accurate reading, the engine must be switched off .
The expansion tank in your vehicle is equipped with an electric
coolant level sensor.
When the coolant level is too low, the warning light in the Auto­
Check System =>
page 30will blink until you add coolant and the
level has been restored to normal. Even though there is an electric
coolant level sensor, we still recommend you check the coolant level
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event
of coolant loss, the cooling system should be inspected immedi­
ately by your authorized Audi dealer. It is not enough merely to add
coolant.
In a
sealed system, losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating.
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant. Adding radiator repair fluid may adversely affect the tune- _..

Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established 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. •
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
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected . This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow . Winter tires (snow tires) must always be fitted on all four wheels
.
Compatible tire pressure monitoring sensors* must be installed on
all four winter tires for the tire pressure monitoring system* to func­
tion properly ~
page 256.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes . Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to
a depth of 0.157 inch (4 mm) .
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel
~ page 254.
Please always remember that winter tires may have a lower speed
rating than the tires originally installed on your vehicle at the time
it was manufactured . Please see~
page 256, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at which the tires can be driven.
The speed rating letter code(~
page 256) is on the side wall of the
tire
~ page 254.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation, loss of control, crashes and serious _,,

• After any impact, immediately inspect your tires or have them
inspected by the nearest authorized Audi dealer. Replace a
damaged tire as soon as possib le .
• Inspect your tires every 2,000 miles (3,000 km) for damage and
wear. Damage is not always easy to see. Damage can lead to loss of
air and underinflation, which could eventua lly cause tire failure. If
you believe that a tire may have been damaged, replace the tire as soon as possible .
• These tires may wear more quickly than others.
• Please a lso remember that, whi le these tires deliver responsive
handling, they may ride less comfortably and make more noise than
other choices.

c ondi tio ns
All tires are designed for certain purposes. The low aspect ratio,
u ltra high performance tires originally ins tal led o n your vehicle are
intended for maximum dry and wet road performance and hand ling.
They are no t suitable for cold, snowy or icy weather conditions . If
you drive under those circumstances, you should equip your vehicle
with al l- season or winter tires, which offer better traction under
those conditions. We suggest you use the recommended snow or
a ll-season tires specified for your vehicle, or their equiva lent.
Refer to~
page 259for more detai led information regarding winter
tires. •

[ i ] Tip s
• In the case of an intentiona l loss of air pressure, such as when
readjusting tire pressure, the pressure must be stored again after ­
ward =>
page 265.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• The ye llow symbol disappears when the tire pressure is
corrected and the new pressure is stored in the system=>
page 265.
• After changing a wheel or rep lacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels . In addition, you
must then initialize the new tire pressures in the tire pressure moni ­
toring system=>

Maintenance
General
Your vehicle has been designed to help keep maintenance require­
ments to a minimum.
However, a certain amount of regular maintenance is still necessary
to assure your vehicle's safety, economy and reliability.
For detailed vehicle maintenance consult your Warranty
& Mainte­
nance booklet.
Under difficult operating conditions, for example at extremely low
outside temperatures, in very dusty regions, when towing a trailer
very frequently, etc., some service work should be performed
between the intervals specified. This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
ci> For the sake of the environment
By regularly maintaining your vehicle, you help make sure that emis­
sion standards are maintained, thus minimizing adverse effects on
the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the generally increasing technical
complexity of today's automobiles, have steadily reduced the scope
of maintenance and repairs which can be carried out by vehicle
owners.
Also, safety and environmental concerns place very strict
limits on the nature of repairs and adjustments to engine and trans­
mission parts which an owner can perform.
Controls and equip­
ment Safety first Vehicle operation
Maintenance, adjustments and repairs usually require special tools,
testing devices and other equipment available to specially trained
workshop personnel in order to assure proper performance, reli­ ability and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
operation and reliability of your vehicle and even void your vehicle
warranty. Therefore, proof of servicing in accordance with the main­ tenance schedule may be a condition for upholding a possible
warranty claim made within the warranty period.
Above all, operational safety can be adversely affected, creating unnecessary risks for you and your passengers.
If in doubt about any servicing, have it done by your authorized Audi
dealer or any other properly equipped and qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu­
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the facilities, original parts and trained specialists
to keep your vehicle running properly .
Performing limited maintenance yourself
The following pages describe a limited number of procedures which
can be performed on your vehicle with ordinary tools, should the
need arise and trained personnel be unavailable. Before performing
any of these procedures, always thoroughly read all of the appli­
cable text and carefully follow the instructions given. Always rigor­
ously observe the
WARNINGS provided.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& and=> & in "Working in the engine
compartment" on
page 224.
& WARNING
• Serious personal injury may occur as a result of improperly
performed maintenance, adjustments or repairs.
