In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLC). The DLC is located to the right of
the hood release =>
page 24, fig. 10.
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=>
page 15, fig. 5 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabilized. This indicates that the MIL is working properly.
If the light does not go out after the engine is started, or illuminates
while you are driving, a malfunction may exist in the engine system.
If the light starts flashing, the catalytic converter could be damaged .
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer .
If the light illuminates, the electronic speed limiter may also be
malfunctioning . For more information=>
page 25, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate =>
page 213. •
Electronic speed limiter
Your vehicle may be factory equipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle . To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter. The elec-
Controls and equip ­

tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information =>
page 246.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Light (MIU•"" will illuminate. If this
occurs, contact the nearest authorized Audi dealer for assistance.
& WARNING
Always observe the posted speed limits and adjust your speed to
suit prevailing road, traffic and weather conditions. Never drive
your vehicle faster than the maximum speed rating of the tires installed. •

Using the previously recommended setting is the quickest way to
achieve a comfortable climate in the vehicle. This setting should
therefore only be changed when personal comfort levels or certa in
circumstances require it.
The climate controls are a combination of automatic heating and
ventilation systems and a cooling system which dehumidifies and cools the air inside the vehic le .
The climate controls automatically maintain a temperature once it has been set. The temperature of the air from the vents, fan speed
(air volume) and air dist ribu tion are a lso automatically adjus ted . The
system also takes into account strong sunshine so that manual
adjus tment is not necessary. So in almost all cases,
a ut omatic mode
offers the best conditions for the comfort of the occupants at all
times of the year~
page 88.
Ple ase not e:
In cooling mode, relative humidity in the interior is reduced. This
prevents the windows from fogging up .
When relative humidity and temperatures outside are high,
conden ­
s ate
can drip from the air conditioning evaporator and form a pool
of water under the vehicle . This is normal and not an indication of a
leak!
When outside temperatures are low, the fan does no t switch to a
higher speed until the coolant has reached an adequate tempera­
ture, with the exception of t he defrost setting .
When accelerating at wide-open throttle, the air conditioning compressor is temporarily switched off to maintain fu ll engine
power.
In order to ensure engine cooling under extreme engine loads, the
compressor is switched off if coolant temperatures climb too high ...

The pollutant filter (particle filter) ensures that contaminants in the
outside air (such as dus t or p ollen) are greatly reduced or stopped.
The air is also filtered in recirculation mode.
T he pollutan t fil te r element must be changed accord ing to the inter ­
vals specified in the maintenance schedule so that the air condi­
tioning system's performance is not adversely affected.
If the filter's effectiveness is weakened by driv ing t he vehic le in
areas with heavi ly polluted outside air, the filter element should also
be changed in between the listed services .
& WARNING
For safety re ason s, it is impo rtant that all window s are free of i ce ,
snow, and condensat ion . Onl y then is good visibility ensured .
Plea se familiari ze your self with the correct operation of the air
conditioning and how to dehumidify /defrost the windows .
0 Note
• If you suspect that the climate controls have been damaged,
switch the system off to avoid damag ing it, and have it inspected by
an author ized Audi dealer.
• Audi climate control system repairs require special expertise and
t he proper tools. You shou ld contact an authorized Audi dealer in
the event o f malfunctions.
[ i ] Tips
• To avo id adverse ly affecting heating and cooling performance
and to prevent condensation on the windows, the air intake in front
of the windsh ield must be free of ice, snow, and leaves.
• The air coming from the vents and circulating through the entire
inter ior is extracted through the outlet slots in the side panels in the
luggage compartment. Make sure that the outlet slots are not
covered by clo th ing, etc.
• Climate control works most effectively if the windows are closed .
H owever, if the interior of a parked vehicle is extremely hot from the
sun's rays, briefly opening the windows can speed up the cooling
process. •

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety risks for everybody in the vehicle increase and you also
Controls and equip­ ment Safety first Vehicle operation
become a
hazard to everyone else on the road =>&, .There ­
fore:
- Do not let yourself be distracted by passengers or by
using a cellular telephone.
- NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc .).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense.
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed.
in. WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

Airbag system -----------------=~-
Airbag system
Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For airbags to
do their job, occupants must always properly wear their
safety belts and be in a proper seating position.
For your safety and the safety of your passengers, before
driving off, always:
- Adjust the driver's seat and steering wheel properly
~ page 116,
-Adjust the front passenger's seat properly~ page 70,
-Wear safety belts properly~ page 128,
- Always properly use the proper child restraint to protect
children~
page 157.
In a collision airbags must inflate within the blink of an eye and with
considerable force. The supplemental airbags can cause injuries if
the driver or the front seat passenger are not seated properly. There ­
fore in order to help the airbag to do its job, it is important, both as
a driver and as a passenger to sit properly at all times.
By keeping room between your body and the steering wheel and the
front of the passenger compartment, the airbag can inflate fully and
completely and provide supplemental protection in certain frontal
collisions =>
page 116, "Proper occupant seating positions". For
details on the operation of the seat adjustment controls=>
page 70
and=> page 71.
It's especially important that children are properly restrained
=>
page 157.
Controls and equip­ ment Safety first Vehicle operation
There is a lot that the driver and the passengers can and must do to
help the individual safety features installed in your Audi work
together as a system.
Proper seating position is important so that the front airbag on the
driver side can do its job. If you have a physical impairment or
condition that prevents you from sitting properly on the driver seat
with the safety belt properly fastened and reaching the pedals, or if
you have concerns with regard to the function or operation of the
Advanced Airbag System, please contact your authorized Audi
dealer or qualified workshop, or call Audi Customer CARE at 1-800-
822 -2834 for possible modifications to your vehicle.
When the airbag system deploys, a gas generator will fill the
airbags, break open the padded covers, and inflate between the
steering wheel and the driver and between the instrument panel
and the front passenger. The airbags will deflate immediately after
deployment so that the front occupants can see through the wind ­
shield again without interruption.
All of this takes place in the blink of an eye, so fast that many people don't even realize that the airbags have deployed. The airbags also
inflate with a great deal of force and nothing should be in their way
when they deploy. Front airbags in combination with properly worn
safety belts slow down and limit the occupant's forward movement .
Together they help to prevent the driver and front seat passenger
from hitting parts of the inside the vehicle while reducing the forces acting on the occupant during the crash. In this way they help to
reduce the risk of injury to the head and upper body in the crash.
Airbags do not protect the arms or the lower parts of the body.
Both front airbags will not inflate in all frontal collisions. The trig­
gering of the airbag system depends on the vehicle deceleration
rate caused by the collision and registered by the electronic control
unit. If this rate is below the reference value programmed into the
control unit, the airbags will not be triggered, even though the car
may be badly damaged as a result of the collision. Vehicle damage,

& WARNING (continued)
• Airbag work most effectively when used with properly worn
safety belts .
• Therefore, always wear your safety belts and make sure that
everybody in your vehicle is properly restrained .
& WARNING
A person on the front passenger seat, especially infants and small
children, will receive serious injuries and can even be killed by
being too close to the airbag when it inflates .
• Although the Advanced Airbag System in your vehicle is
designed to turn off the front passenger airbag if an infant or a
small child is on the front passenger seat, nobody can absolutely
guarantee that deployment under these special conditions is
impossible in all conceivable situations that may happen during
the useful life of your vehicle.
• The Advanced Airbag System can deploy in accordance with
the "low risk" option under the U.S. Federal Standard if a child that
is heavier than the typical one-year old child is on the front
passenger seat and the other conditions for airbag deployment
are met.
• Accident statistics have shown that children are generally safer
in the rear seat area than in the front seating position.
• For their own safety, all children, especially 12 years and
younger, should always ride in the back properly restrained for
their age and size . •
Advanced front airbag system
Your vehicle is equipped with a front Advanced Airbag System in
compliance with United States Federal Motor Vehicle Safety Stan ­
dard 208 as applicable at the time your vehicle was manufactured. The
front Advanced Airbag System supplements the safety belts to
provide additional protection for the driver's and front passenger's
heads and upper bodies in frontal crashes . The airbags inflate only
in frontal impacts when the vehicle deceleration is high enough.
The front Advanced Airbag System for the front seat occupants is
not a substitute for your safety belts . Rather, it is part of the overall
occupant restraint system in your vehicle. Always remember that
the airbag system can only help to protect you, if you are sitting
upright, wearing your safety belt and wearing it properly. This is why
you and your passengers must always be properly restrained, not
just because the law requires you to be.
The Advanced Airbag System in your vehicle has been certified to
meet the "low risk" requirements for 3 and 6 year -old children on the
passenger side and very small adults on the driver side. The low risk
deployment criteria are intended to help reduce the risk of injury
through interaction with the front 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 12 months old and younger who are
restrained on the front passenger seat in child restraints that are
listed in the Standard=>
page 159, "Child restraints and Advanced
Airbags" .
"Suppression" requires the front airbag on the passenger side to be
turned off if:
• a child up to about one year of age is restrained on the front
passenger seat in one of the rear-facing or forward-facing infant
restraints listed in Federal Motor Vehicle Safety Standard 208 with
which the Advanced Airbag System in your vehicle was certified. For
a listing of the child restraints that were used to certify your
vehicle's compliance with the US Safety Standard=>
page 159,
• weight less than a threshold level stored in the control unit is
detected on the front passenger seat. .,
