On-Board Diagnosti cs
Fig . 15 Location of
Data Link Connector
(DLC)
On-Board Diagnostics monitors the components of your emission
control system. Each controlled component in your engine system
has been assigned a code. In case of a malfunction, the component
will be identified and the fault stored as a code in the control module memory .
Th e MIL lamp may also illuminate if there is a leak in the on -board
fuel vapor recovery system. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then check that the fuel filler
cap is properly closed
=> page 246.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan tool for
OBDl.
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 engine hood release lever=> fig. 15.
Your authorized Audi dealer or a qualified service station can inter ­
pret the code and perform the necessary repair. •
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
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating. For more information=>
page 279, "New tires and
replacing tires and wheels".
If the engine control unit receives faulty vehicle roadspeed signals,
the Malfunction Indicator Lamp (Mill 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. •
Auto-Check Control
Introduction
The Auto-Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly. The Auto-Check control works as
long as the ignition is on, as well as whenever the vehicle is driven.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument cluster display.
You will also hear an audible warning tone. The displays are color
coded in either red or yellow depending on their level of priority. .,_

The se lector lever must be in Nor P. If one of the driving positions
is engaged a safety switch w ill preven t the eng ine from being
started. See also=> page 120 .
Before you move the selector lever from the P position, you must
a lways apply the brake peda l before and wh ile de press ing the
button in the hand le of the selector lever.
& WARNING
• Unintended vehicle movement can cause serious injury .
- When the selector lever is in a driving position , the vehicle
may creep , even at idle speed . Therefore do not release the
parking brake or foot brake until you are ready to move,
because power is transmitted to the wheels as soon as a
driving position is engaged.
- Do not accelerate while selecting a driving position . At this
time the engine must be at idle speed so that undue stress is
not placed on the clutches in the transmission .
- Remember: -even when stopped briefly with the automatic
transmission in "D ", "S " or "R ", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
ba ckward . When stopped , keep the brake pedal fully depressed
and use the parking brake if necessary to keep the vehicle from
rolling .
• If the selector lever is unintentionally moved into N while you
are driving , take your foot off the accelerator pedal and wait for
the engine to return to idle speed before selecting a driving posi ­
tion .
• Never shift into "R " or "P " when the vehicle is in motion .
• Never get out of the driver 's seat when the engine is running .
• If you must get out of the vehicle , move the selector lever
securely into the P pos ition and apply the parking brake firmly .
• If the engine must remain running , never have any dr iving posi ­
tion engaged when checking under the hood . Make sure the
selector lever has securely engaged and is locked in "P " with the

When the electronic control unit registers a low severity crash and
the safety belt is being used, the airbag will not deploy . If the safety
belt is not being used, the first stage deploys, followed by the
second stage afte r a much later time in the crash sequence.
If the electronic control unit registers a crash of medium severity,
the first stage of the airbag deploys followed by the second stage at
a much later t ime in the crash sequence -regardless o f whether the
safety belt is being used or not. In higher severity crashes as regis­
tered by the e lectronic contro l unit, both the first and second stages
deploy almost at the same time.
On the passenger side, regardless of safety belt use, the airbag will
be turned off if the weight on the passenger seat is less than the
amount programmed in the e lectronic control unit . The front airbag
on the passenger s ide will a lso be turned off if one of the child
safety seats that has been certified under Federal Motor Vehicle
Safety Standard 208 has been recognized on the seat. The
PASSENGER AIR BAG OFF light comes on and stays on to tell you
whe n the front Advanced Airbag on the passenger side has been
turned off=>
page 170, "Child restraints on the front seat -some
impor tan t things to know".
& WARNING
To reduce the risk of injury when an a irbag infl ates , always wear
s afet y belts properly .
• If you are unre stra ined , leaning forward , sitting sideway s or out
of position in any w ay, your risk of in jur y i s mu ch hi gher.
• You will als o recei ve se riou s injurie s and could e ven b e killed if
you are up again st the airbag or too clo se to it when it inflate s -
even with an Advanced Airbag =>

Airb ag syst em
More important things to know about front
airbags
F ig . 173 Inflated front
airba gs
Safety belts are important to he lp keep front seat occupants in the
proper seated position so tha t airbags can unfold properly and
provide supplementa l protection in a fronta l collision.
The front airbags are designed to provide additional protection for
the chest and face of the driver and the front seat passenger when: • safety belts are worn properly,
• the seats have been positioned so that the occupant is properly
seated as far as possib le from the a irbag,
• and the head restraints have been properly adjusted.
Because a irbags inflate in the blink of an eye with great force, thi ngs
you have on your lap or have placed on the seat could become
dangerous projectiles, and be pushed into you if the airbag inflates.
When a n airbag deploy s, fine dust is released . This is normal and is
not caused by a fire in the vehicle. This dust is made up mostly of a
powder used to lubrica te the airbags as they deploy . It could irri tate
skin.
It is important to remember that while the supplemental airbag
system is designed to reduce the likelihood of serious injuries, other
injuries, for example swelling, bruising and minor abrasions, can
a lso happen when airbags infla te . Airbags do no t pro tect the arms ...
