On-Board Diagnostics
Fig . 24 Locat ion of Data Link Connector (D LC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent w ill be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system .
If the light illuminates after a refuel ing, stop the
veh icle and make sure the fue l filler cap is prop­
erly closed (on ly vehicles with gasol ine engine)
¢page 298.
In order to make an accurate d iagnosis, the stor­
ed data can only be disp layed using specia l diag­
nostic equipm ent (ge ne ric scan tool for OBD) .

In order to connect the special diagnostic equip­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
¢ fig. 24.
Your authorized Audi dea le r or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

_& WARNING
To reduce the risk of injury when an airbag in­
flates, always wear safety belts properly.
- If you are unrestrained, lean ing forward, sit­
t ing s ideways or out of pos ition in anyway,
your risk of injury is much h igher.
- You will also receive serious injur ies and
could even be killed if you are up aga inst the
airbag or too close to it when it inflates -
even with an Advanced Airbag
¢page 253.
More important things to know about front
a irbags
F ig. 221 Inflated front airbags
0 0 M
-..:, ... m
Safety belts are important to help keep front
seat occupants in the p roper seated position so
that a irbags can unfold properly and provide sup­
p lemental protection in a frontal collision.
The front airbags are designed to provide addi­
tional protection for the chest a nd face of the
d river and the front seat passenger when:
- safety belts are worn properly
- the seats have been positioned so that the oc-
cupant is properly seated as far as possible
from the airbag
- and the head restraints have been properly ad-
justed
Because airbags inflate in the blink of an eye with
great force, things you have on your lap or have placed on the seat could become dangerous pro­
jectiles, and be pushed into you if the airbag in­
flates .
~ When an a irbag deploys, fine dust is released.
8 This is normal and is not caused by a fire in the
~ vehicle. Th is dust is made up mostly of a powder
co
Airb ag sys tem
used to lubricate the airbags as they deploy. It
could irritate skin.
It is important to remember that wh ile the sup­
plementa l airbag system is designed to red uce
the likelihood of serio us injuries, other injur ies,
for example swelling, bruising and minor abra­ s ions, can also happen when airbags inflate. Air­
bags do not protect the arms or the lower parts
of the body. Front airbags supplement the three­
point safety belts on ly in some frontal collisions
in which the vehicle deceleration is high e nough
to deploy the airbags .
Fron t airb ags will not depl oy:
- if the ignition is switched off when a crash oc-
curs
- in side collisions
- in rear-end collisions
- in rollovers
- when t he crash deceleration measured by the
airbag system is less than the m in imum thresh­
old needed for airbag dep loyment as registe red
by the electronic control unit
Th e front passenger airbag also will not
deplo y:
- when the front passenger seat is not occupied,
- when the e lectr ica l ca pacitance measured by
the capacitive passenger detection system for
the front passenger seat indicates that the pas­
senger s ide frontal a irbag must be switched off
by the electronic control unit (the
PASSENGER
AIR BAG OFF
11,;; light ¢ page 265 comes on
and stays on).
A WARNING
-Sitt ing in the wrong position can increase the
risk of ser ious injury in crashes.
- To reduce the risk of injury when the airbags
inflate, the drive r and passengers must al­
ways sit in an up right posit ion, must not
lea n aga ins t or place any part of their body
too close to the area where the airbags are
located.
- Occupants who are unbelted, out of posi tion
or too close to the airbag c an be serio usly
inj ured by an airbag as it unfolds with great
force in the blink of an eye¢

reproductive harm. In addition, certain flu­
ids contained in vehicles and certain prod­
ucts of component wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other
reproduct ive harm.
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
