On-Board Diagnostic
System (OBD)
Malfunction indicator lamp (MIL)
The malfunction indicator lamp (MIL) ¢.j in the
instrument cluster is part of the On-Board Diag­
nostic System (OBD II).
The warning/indicator light turns on when the ig­ nition is switched on and turns off once the en­
gine is started and is running in idle at a stab le
speed. This indicates that the MIL is functioning
correct ly.
If the light does not turn off after starting the
engine
or turns on while driving, this may indi­
cate there is a malfunction in the engine.
If the
indicator turns on, the catalytic converte r may be
damaged .
Drive
with reduced engine performance (avoid
high speeds for extended periods of time and/or
fast acceleration) and have the malfunction cor­
rected. See an authorized Aud i dealer or autho r­
ized Audi Service Facility.
The MIL may also turn on if the fuel filler cap i s
not cl osed correctly

On-Board Diagnostics
Fig. 5 Location o f Data Li nk Con necto r (OLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
s igned a code. In case of a malfunction , the com­
ponent will be identified and the fault sto red 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 refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed (only vehicles with gasoline engine)
r::'.>page 153 .
In order to make an acc urat e diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for 080).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data Lin k Connector
(DLC). The DLC is located to the right of the hood
release ¢
fig. 5.
Your authorized Aud i dea ler or qualified work­
shop can interpret the code and perform the nec­
essary repair.
_& WARNING ~
Do not use the diagnostic connector for per-
sona l use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!

Driving
P - Park
This selector lever position prevents the vehicle
from rolling. You can only shift into Park when
the vehicl e is
stationary ¢&. .
To shift in and out of the P selector lever posi ­
tion, press the interlock button in the selector
lever
while pressing the brake pedal.
R- Reverse
Only shift into reverse gear when the vehicle is
stationary and the engine is running at idle
speed ¢&, .
To select the R selector lever position, press the
interlock button
while pressing the brake pedal.
N - Neutral
The transmission is in idle in this position.
To engage the N selector lever position, press the
button on the selector lever and shift into the N
position.
To
move from selector lever position out of N,
you must press the brake pedal and the vehicle
must be traveling less than 1 mph (2 km/h) or be
stationary.
DIS -Normal position for driving forward
In the D/S selector lever position, the transmis­
sion can be operated either in the normal D mode
or in the S sport mode. To select the S sport
mode, pull the selector lever back briefly. Pulling
the lever back again will select the normal D
mode. The instrument cluster display shows the
selected driving mode .
In the
normal mode D, the transmission auto­
matically selects the suitable gear ratio. It de­
pends on engine load, vehicle speed and driving
style.
The engine's power reserves are used fully in the
Sport mode S. Shifting may become noticeable
when accelerating.
To
move from selector lever position N to D, you
must press the brake pedal and the vehicle must
be traveling less than 1 mph (2 km/h) o r be sta­
t ionary ¢&, .

A WARNING
-
Read and follow all WARNINGS.
-The vehicle can roll
even if the ignition is
switched off.
- Never select R or P while driving, because
this increases the risk of an accident.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake in all selector
lever positions (except P) when the engine is
running .
- Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged . Otherwise, the vehicle will imme­
diately start to
move -sometimes even if
the parking brake is firmly applied. This in­
creases the risk of an accident.
- To reduce the risk of an accident, do not
press the accelerator pedal when changing
the selector lever position while the vehicle
is stationary and the engine is running.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Before you or other persons open the hood
and work on a running engine, the selector
lever must be in the P position and the park­ ing brake must be applied to reduce the risk
of an accident . Always read and follow the
applicable warnings ¢
page 155, Working
in the engine compartment.
- Read and following all WARNINGS¢&. in
Driving tips on page 69 .
(D Note
Never let the vehicle roll downhill with engine
off and the selector lever in the N position,
because this could damage the automatic
transmission and catalytic converter.
(D Tips
- If you accidentally select N while driving,
take your foot off the accelerator pedal and .,.
