Introduction
The Driver information display inside the instru­

portant information.

With the ignition on, the display in th e Driver In­
formation System shows the following informa­
tion :

Auto Check Control
Some functions and vehicle components are
scanned for their operating status when you
switch the ignition on and while you are driving. Malfunctions or required service procedures are
signaled audibly and indicated by red and yellow
illum inated symbols and reminders in the dis­
play.
A WARNING
--
- Never rely exclus ively on the outside tem­
pe rature display to determine if a road sur­
face is icy or not. Keep in m ind that road
surfaces, especially bridges and overpasses,
could be ice covered and slippery even at an
outside temperat ure above 41 °f (+S °C).
- Always remember, even if the "snowflake"
symbol (ice warning) does not appear in the
display, black ice could be on the road.
- Always reduce your speed and dr ive with
specia l care in cold weather conditions when
the chance of encountering icy road surfaces
increases.
(j) Tips
If the vehicle is stationary, or if you are driv­
ing at a very low speed, the temperature
shown in the disp lay might be slightly higher
than the actual outside temperature. This is
caused by the heat being radiated from the
engine.

On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates 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 illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢
page 200.

On-Board Diagnostics
Fig. 17 Loca tion of Data Link Connector (DLC)
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 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 refueling, stop the
vehicle and make sure the fuel f iller cap is prop­
erly closed
¢ page 200.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (gener ic scan tool for OBD).
In order to connect the special d iagnost ic equip­
ment, push the p lug into the Data L ink Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 17.
Your authorized Audi dealer 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 co lli­
sion!
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 may be less than the maxi­
mum speed of your vehicle . To reduce the risk of .,.

Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the veh icle inter ior. It
is the most effective when the windows and sun ­
roof are closed. If there is a build-up of heat in­
side the vehicle, ventilation can help to speed up
the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture .
Condensat ion from the cooling system can drip
and form a puddle of water under the veh icle.
This is normal and does not mean there is a leak.
P ollutant filt er
The pol lutant filte r removes pollutants such as
dust and pollen from the a ir.
The air pollutants filter must be changed at the intervals specif ied in your Warranty
& Mainte­
nance booklet, so that the a ir cond it ione r can
properly work.
If you drive your vehicle in an area with high air pollut ion, the filter may need to be changed
more frequently than specified i n your Aud i War­
ranty
& Maintenance booklet. If in doubt, ask
your author ized Audi Service Advisor for advice.
Ke y cod ed setting s
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
.8, WARNING
Reduced visib ility is dangerous and can ca use
accidents.
- For safe dr iv ing it is very impo rtan t that all
windows be free of ice, snow and condensa­
t ion .
76
- Complete ly familiarize yourself with the
proper use and function of the heating and
ventilation system and espec ially how to de­
fog and defrost the wi ndows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­ ing and vent ilation system. The washer solu­
tion may freeze on the windshield and re­
duce visibi lity.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a q ualified dealership.
- Repa irs to the Aud i air cond itioner requ ire
special techn ica l know ledge and spec ial
tools. Contact an a uthorized Audi dealer fo r
assistance.
@ For the sake of the environment
By reduc ing the amo unt of fuel you use, you
also reduce the amount of pollutants emitted
into the a ir.
(D Tips
- Keep t he a ir intake slots (in front of the
windshield) free from ice, snow and debr is
in orde r to maintain the prope r funct ion of
the climate control system .
- The energy management sys tem may sw itch
the seat heating* o r rea r window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.
