Advanced front airbag system and children
Your vehicle is equipped with an "Advanced Airbag System" in
complia nce with United States Federa l Motor Vehicle Safety Stan ­
dard (FMVSS) 208 as applicable at the time your vehicle was manu ­
factu red. T
he Advanced Airbag system in your vehicle has been certified to
meet the " low -risk" requiremen ts for 3 -and 6 -year o ld children on
the passenger side and smal l adults on the driver side . The low risk
deployment criteria are intended to reduce the risk of injury through
interaction with the airbag that can occur, for example, by being too
close to the steering wheel and instrument panel when the airbag
inflates. In addition, the system has been certified to comply with
the "suppression" requirements of the Safety Standard, to turn off
the front airbag for infants up to 12 months who are restrained on
the front passenger seat in child restraints that are listed in the
S tandard.
Even though your vehicle is equipped with an Advanced Airbag
system, all ch ildren, especially those 12 years and younger, should
always ride in the back seat properly restrained for their age and
size . The airbag on the passenger side makes the front seat a poten­
tially dangerous p lace for a child to ride. The front seat is not the
safest p lace for a child in a forward -facing child safety seat. It can be
a very dangerous p lace for an infant or a larger ch ild in a rearward­
facing seat. •
Advanced Airbags and the weight-sensing
mat in the front seat
The Advanced Airbag System in your vehicle detects the presence
of an infant or child in a chi ld restraint on the front passenger seat
using the weight -sensing mat in the seat cushion and the sensor
below the safety belt latch on the front passenger seat that
measures the tension on the safety belt.
The weight -sensing mat measures total weight of the chi ld and the
child safety seat and a child blanket on the front passenger seat . The
weight on the front passenger seat is related to the design of the
child restraint and its "footprint", the size and shape of the bottom
of the child restraint as it sits on the seat . The weight of a child
restraint and its "footprint" vary for different kinds of child ..,.

-----------------------------------------~C::_! h~ i~ ld ~ S~a !_!f ~e _!;tY L _ffllll
restraints and for the different models of the same kind of child
restraint offered by child restraint manufacturers.
The weight ranges for the individual types, makes and models of
child restraints that the NHTSA has specified in the Safety Standard
together with the weight ranges of typ ical infants and typical 1 year­
old child have been stored in the control unit of the Advanced
Airbag System. When a child restraint is being used on the front
passenger seat with a typical 1 year -old child, the Advanced Airbag
System compares the weight measured by the weight sensing mat
with the information stored in the electronic control unit.
The electronic control unit also registers the tension on the front
passenger safety belt. The tension on the safety belt for the front
passenger seat will be different for an adult who is properly using
the safety belt as compared to the tension on the belt when it is
used to attach a child restraint to the seat. The sensor below the
latch for the safety belt for the front seat passenger measures the
tension on the belt . The input from this sensor is then used with the
weight to "decide" , whether there is a child restraint with a typical 1
year-old child on the front passenger seat and whether or not the airbag must be turned off.•
Child restraints and Advanced Airbags
Regardless of the child restraint that you use, make sure that it has
been certified to meet United States Federal Motor Vehicle Safety
Standards and has been certified by its manufacturer for use with
an airbag. Always be sure that the chi ld restraint is properly
installed at one of the rear seating positions. If in exceptiona l
circumstances you must use it on the front passenger seat, carefully
read all of the information on child safety and Advanced Airbags
and heed a ll of the applicable WARNINGS. Make certain that the
child restraint is correctly recognized by the weight -sensing mat
inside the front passenger seat, that the front passenger airbag is
turned off and that the airbag status is always correctly signaled by
th e
PASSENGER AIR BAG OFF light .
Controls and equip­
ment Safety first Vehicle operation
Many
types and models of child restraints have been available over
the years, new mode ls are introduced regularly incorporating new
and improved designs and older mode ls are taken out of produc­
tion. Child restraints are not standardized . Child restraints of the
same type typically have different weights and sizes and different
'footprints,' the size and shape of the bottom of the chi ld restraint
that sits on the seat, when they are installed on a vehicle sea t. These
differences make it virtual ly impossible to certify comp liance with
the requirements for advanced airbags with each and every child
restraint that has ever been sold in the past or will be sold over the
course of the usefu l life of your vehic le.
For this reason, the United States National Highway Traffic Safety
Administration has pub lished a list of specific type, makes and
models of child restraints that must be used to certify compliance
of the Advanced Airbag System in your vehicle with the suppression
requirements of Federal Motor Vehicle Safety Standard 208. These
child restraints are:
A. Car beds, manufactured on or after September 1,
2004:
• Cosco Dream Ride 02-719
B. Rear facing child restraint systems, manufactured
on or after September 1, 2004:
(When the restraint system comes equipped with a removable base,
compliance has to be certified with or without the base) .

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent .
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle systems such as, for example, eng ine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le -related data
during norma l vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic cont rol modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit . Some
of the data then stored may relate to vehic le speed, direction,
braking as we ll as restraint system use and performance in the
event of a crash or other condition. Stored data can only be read and
downloaded with special equip men t.
Electronic Stabilization Program (ESP)
General
The Electronic Stabili ty Program increases driving
stability.

cons ole with E SP
sw itch
With ESP, control over the veh ic le is increased in situations when
the vehicle is close to the limits of grip, such as during acce leration
and in curves. ESP reduces the risk of skidding a nd improves vehicle
stability under all road conditions . It operates at all speeds .
The Anti-Lock Brake System (ABS), E lec tronic Differentia l Lock (EDS)
and Anti-Slip Regulation System (ASR) are integrated in the Elec­
tronic Stability Program .
How ESP work s
The ESP control unit processes the fo llowing data from high-sensi ­
tive sensors : the rotational speed of the vehicle about its vertica l
axis, fore -and -aft and lateral acceleration forces, brake pressure and
steering angle.
Using steering ang le and vehicle speed, the direction the driver
wishes to travel is determined and continuously compared with
t,.

actual vehicle behavior. If the two do not match, for example when
th e vehicle begins to skid, ESP brakes the appropriate wheel auto­
matical ly .
The vehicle is stabilized again by the forces acting on the wheel
during braking. With an oversteering vehicle (tendency for the rear
end to skid out of the curve), the brake application is mainly at the
front wheel on the outside of the curve, with an
understeering
vehicle (tendency to run wide in the curve) at the rear wheel on the
inside of the curve or additionally at the other wheels as needed.
This brake application is accompanied by noises.
ESP works in conjunction with ABS=>
page 192. If there is malfunc ­
tion in the ABS, ESP is also inoperative.
Activating
The ESP is automatica lly activated when the engine is started, and
it performs a self-test. As soon as the test is completed, the system
is in normal operating mode. With ASR deactivated, or with ESP/ASR
deactivated, pressing the button=>
page 188, fig. 158 returns the
system to normal operation.
Deactivating
ESP should normally be activated at all times because this ensures
optimum vehicle stability. Only in certain exceptional cases it does
make sense to deactivate Anti-Slip Regulation (ASR) or the Elec­
tronic Stability Program (ESP) by pressing the button =>
page 188,
fig. 158. Both deactivation stages can only be activated from normal
mode .
Deactivating ASR
Tap the switch. Deactivation is indicated by slow flashing of the ESP
lamp in the instrument cluster. In certain situations (e .g. driving
with snow chains, in deep snow or on loose ground, or when
rocking the car free), it may be necessary to deactivate ASR.
Deactivating ESP/ASR
Press the button for more than 3 seconds. Deactivation is indicated
by the ESP lamp in the ins trument cluster staying on permanently.
Controls and equip­
ment Safety first Vehicle operation
Intelligent technology
This
deactivates the Electronic Stability Program (ESP) in addition to
ASR. No Elec tronic Stability System operation and no Anti -Slip
Regulation is available across the entire speed range; ASR and ESP
are activated only when the brakes are used for the duration of the
braking action and remain active until a stable vehicle condition has
been reached. There is no driving situation which requires ESP to be
deactivated, so this should only be done if the driver's skill and the
traffic situation permit.
& WARNING
• The limits of physics cannot be suspended by ESP. Even in vehi­
cles with ESP. you should always adapt your driving to road and
traffic conditions. This is particularly true on a slippery and wet
road . Do not be tempted by the increased safety provided to take
risks -danger of an accident!
• Please note that when ASR or ESP /ASR is deactivated , the drive
wheels can spin on icy and slippery roads and the vehicle can
break away -danger of skidding!
Electronic differential lock CED1
.)
The electronic differential lock monitors the rotational
speed of the drive wheels.
General notes
The elect ronic differential lock (EDU helps the car to start moving,
accelerate and c limb a gradient on surfaces providing poor or
a lmost no grip. Without EDL, this would be difficult, if not impos ­
s ible.
How the system works
The EDL operates automatical ly. It monitors the rotationa l speed of
the drive wheels on an axle with the help of the ABS sensors
=>
page 192. If a noticeable difference in rotational speed between
the drive wheels on one axle is detected (e.g. on slippery ground
on
one side),
the spinning wheel is braked, thereby transferring power

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.

• 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

(D Note
• When installing new tires, be careful not to damage the valves or

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
