to the other drive wheel or wheels (all-whee l drivel. This is done up
to a speed of about 60 mph (100 km/h). Noises from the brake
system signal that wheel spin is being controlled.
Driving off
When driving off, always be sure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface
with less grip, gradually increase the pressure on the accelerator
pedal until the car starts to move. The wheel less able to transfer
power spins .
Overheating of brakes
To prevent the disc brake of the braked wheel from overheating if
subjected to excessive loads, the EDL cuts out temporarily. The
vehicle remains operational and behaves in the same way as a
vehicle without EDL.
As soon as the brake has cooled down, EDL switches on again auto­
matically.
& WARNING
• When accelerating on slippery surfaces, such as on ice or snow,
always be careful when depressing the accelerator pedal. Even
with the EDL working, the drive wheels can spin and reduce your
ability to control your car. -Risk of crash!
• The increased safety afforded by EDL does not mean that you
can take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
If a fault occurs in the ABS, the EDL is also not functioning. This is
indicated by the ABS warning light=>
page 16. •
Anti-Slip Regulat ion System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Slip Regulation System (ASR) is integrated in the electronic
stabilization program (ESP) . When the vehicle starts up and acceler­
ates, the wheels are prevented from spinning by adjusting the
engine power to match the amount of grip available from the road
surface.
How the system works
ASR performs automatically, i.e. without the driver's intervention.
With the aid of the ABS sensors=>
page 192, ASR monitors the
speed of the driven wheels. If the wheels start to spin, the engine
torque is reduced automatically until the tires find enough grip to
lock onto the road surface. The system is active across the entire
speed range.
Th e ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR will also be out of action.
Activating
The ESP is automatically activated when the engine is started and it
performs a self -test. You can activate a deactivated ASR if required
by pressing the=>
page 188, fig. 158 button. When it is activated,
the message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if required by pressing the button (for
less than 3 seconds)=>
page 188, fig . 158. With the ASR deactivated,
the ESP check light comes on, see=>
page 13. The message ASR off
appears in the display as well.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make
sense to deactivate the ASR. Examples:
• when driving with tire chains

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- _..

• For technical reasons, it is not generally possible to use the
wheel rims from other vehicles. This can hold true for wheels of the
same vehicle type.
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide profile t ires), then
use the spare tire for a short period of time only and drive with extra
care. Replace the f lat tire with the tire matching the others on your
vehic le as soon as possib le.
• If you put different whee ls and tires on your vehic le (e .g. winter
whee ls and tires), you must be certain that the wheels and tires are
compatible with the tire pressure monitoring system*. Otherwise
the system will register a malfunction and a fault message wi ll be
displayed. For more information, contact your authorized Aud i
dea ler.
(D Note
• When installing new tires, be careful not to damage the valves or
tire pressure monitoring system* sensors.
• Never drive without the valve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.

Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C Quality grades can be found where applicable on the tire side wal
l
between tread shoulder and maximum section width~
page 254,
fig. 177 .
For exa mple: Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federal Safety Requ ire­
ments in addition to these grades.
T rea d w ear
The
tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled condit ions on a specified
government test course .
Fo r example, a tire graded 150 wou ld wear one and one hal f (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actua l condi ­
tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differ ­
ences in road characteristics and climate .
Tr act ion
The
traction grades, from highest to lowest, are AA, A, Band C.
T hose grades represent the tire 's ability to stop on wet pavement as
measured under contro lled co nditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance
~ & .
Temp erature
T he
temperature grades are A (the highest), B , and C , represent ing
the tire's resistance to the generation of heat and its abi lity to dissi ­
pate heat when tested under control led conditions on a specified
indoor laboratory test wheel.
Susta ined high temperature can cause the mater ial of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure~& .
T he grade C corresponds to a leve l of performance which a ll
passenger car tires must meet under 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.
& 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 _,,

& WARNING
• When the tire pressure monitoring system warning light is lit,
one or more of your tires is significantly underinflated. You should
stop and check your tires as soon as possible , and inflate them to
the proper pressure as indicated on the vehicle's tire pressure
label =>
page 246 . Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure. Underinfla­
tion also is likely to impair the vehicle's handling and stopping
ability.
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
~ For the sake of the environment
Driving with underinflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire, including the spare , should be checked monthly when
the temperature of the tires is about the same as ambient air
temperature and set to the recommended inflation pressure as
specified on the tire pressure label=> page 246.
• Th e factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system helps the driver monitor tire
pressures, but the driver is still responsible for maintaining the
correct tire pressure.
• Tir e pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged. The valve core, nut, valve sealing and seal washer (replacement kit) needs
to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• Th e tire pressure monitoring system on your Audi was calibrated
using tires with the "AO" or "RO" identification. We recommend
using these tires.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your
authorized Audi dealer.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system to the load you are carrying .
