On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 19, fig. 9 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light il luminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . This indicates that the MIL is working prope rly.
If the light do es 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
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid accelerations) and have the condition
corrected. Contact your authorized Audi dealer.
If the light illuminates, the e lectronic speed limiter may also be
malfunctioning . For more

On -Board Diagnostics
F ig. 15 Locatio n of
Da ta Li nk Co nnecto r
( DL Cl
On-Board Diagnostics monitors the components of your emission
control system . Each control led component in your engine system
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
modu le memory.
The M IL lamp may a lso 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 fi ller
cap is proper ly closed
=> page 269.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnos tic equipment (generic scan tool for
OBD).
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 author ized Audi dealer or a qua lified service station can inter­
pre t the code and perform the necessary repair. •

-Check coolant level :::> page 281.
-Add coolant if necessary=> page 282.
-Continue driving only after the engine coolant
warning/indicator light goes out.
-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
I f the generator warning/indicator light should also illuminate
=> page 22, then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 79, "Emer­
gency flasher
A" .
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded .
Wait until you can no longer see or hear steam or coolant escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 265, "Engine compartment" .
0 Note
Do not continue driving if the-~-symbol illuminates. It indicates a
cooling system malfunction likely to result in serious damage to the
engine. •
Engine oil pressure malfunction ~
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the 9=::;,. symbol appears in the display and blinks, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
Switch off engine, check oil level
Immediate actions
-Pull off the road and stop the vehicle.
-Shut the engine down.
-Check the engine oil level with the dipstick=> page 277.
Dipstick reading checks too lovv
-Top off oil to the proper level => page 278.
-Make sure that the oil pressure warning symbol 9=::;f.
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
-If the 9=::;f. symbol starts flashing again even though the
engine oil level checks OK on the dipstick,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis-
tance.
.,_

[ i J Tips
• The engine oil pressure symbol ~ is not an indicator for a low
engine oil level. Do not rely on it . Instead , check the oil level in your
engine at regular interval s, preferably each time you refuel , and
always before going on a long trip.
• The yellow oil level warning indication requires oil refill or
workshop service without delay . Do not wait until the red oil pre s­
s ure warning symbol
~ starts to fla sh before you respond to the
low oil level warning
-... . By then , your engine may already have
s uffered serious damage. •

Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the fo llowing settings:
- Select and set a temperature between 71 °F (+22 °C) and
84 °F (+29 °C).
- Press the [AUTO
I button.
With this setting, you attain maximum comfort in the least amount
of time . C hange this sett ing, as des ired, to meet your personal
needs .
The climate contro ls are a combination of heating, ventilation and
cool ing systems, which automatica lly reduce humidity and coo l the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically
regu lated to achieve and maintain the desired passenger compart ­
ment temperatu re as quickly as possible.
The system automatically compensates for changes in the outside
temperature and for the intensity of the sunlight entering the
veh ic le. We recommend you use the
Automati c mode=> page 127
for year-round comfort.
Please note the follow ing :
Turn on the air conditioner to reduce hum idity in the veh ic le. This
a lso prevent the windows from fogging up.
Controls and equip ­
ment
When the outside temperature is high and the air is very humid,
c o ndensat ion from the evaporator may drip under the vehicle. This
is normal and does not ind icate a leak.
If the outside temperature is low, the fan norma lly on ly switches to
a higher speed once the engine coolant has warmed up suff iciently .
The air conditioner temporarily switches off when you drive off from a standstill using ful l throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high so that the engine can be adequate ly cooled under extreme
loads .
Air p ollut ants filt er
The air po llutants fi lter (a combined part ic le filter and activated
charcoal filter) reduces or e liminates outside air pol lution (dust, or
pollen) from enter ing the vehic le .
The air po llutants filter must be changed at the intervals specified
in you r Maintenance
& Wa rranty booklet, so that the air cond itioner
can proper ly work.
If you drive your vehic le in an area with high air pol lution, the filter
may need to be changed more frequently than speci fied in your
Audi Maintenance
& Warranty book let. If in doubt, ask your autho­
ri zed Aud i Service Adv isor fo r advice .
& WARNING
Reduced vi sibility i s da ng erou s and can cause accident s.
• For safe driving it is very important that all windows be free of
ice , snow and cond ensa tion .
• Fully familiarize yourself with the proper us e and function of
the heating and ventilation sy stem and e speci ally how to defog
and defrost the window s.

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
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 .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •
