economy message
Fuel economy messages are displayed when fuel consump­
tion is increased by certain conditions. If you follow these
fuel economy messages, you can reduce your vehicle's
consumption of fuel. The messages appear automatically
and are only displayed in the efficiency program. The fuel
economy messages turn off automatically after a certain
period of time.
- To turn a fuel economy message
off immediately after it
appears, press the [
RESET] button ~ page 23, fig. 16@,
or
- Press the function selection switch~ page 23, fig. 16@.
[I] Tips
• Once you have turned a fuel economy message off, it will only
appear again after you turn the ignition on again.
• The fuel economy messages are not displayed in every instance,
but rather in intervals over a period of time. •

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
=;,
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warning/indicator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicates 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 accelerations) and have the condition corrected.
Contact your authorized Audi dealer .
If the light illuminates , the electronic speed limiter may also be
malfunctioning. For more information=;,
page 26, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to illuminate

Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine system
has been assigned a code. In case of a malfunction, the component
wi ll 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 illumi nates after a refueling , stop
the vehicle and make sure the fuel filler cap is properly closed
=>
page 276.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
080).
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 hood release=>
page 25, fig. 20.
Your authorized Audi dea ler or qualified workshop can interpret 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 veh icle. To reduce the risk of sudden tire
fai lure and loss of control if the vehicle is operated at excessive
speeds, you r ve hicl e also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
t ire speed rating. For more information=>
page 307.
If the eng ine control unit receives faulty veh icle road speed signals,
the Malfunction Indicator Lamp (MIL)
11.... 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. •
Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns if the driver exceeds a previous ly
sto red maximum speed. A warning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the
same time, a warn ing symbol appears in the display. The symbol's
appearance might be different in some models.
Th e speed warning system has
two warning thresholds that function
independently of each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maximum speed while you a re
driving . This setting w ill remain in effect until you turn off the igni­
tion, assuming that you have not changed or reset the setting .
Th e speed warning symbol
8 (USA models)/ 8 (Canada mode ls) in
the warning 1 display appears when you exceed the maximum speed.
It goes out when the speed falls below the stored maximum speed.
The speed warn ing symbol w ill also go out if the speed
exceeds the
stored maxim um speed by mo re than about 2S mph (40 km/h) for at
least 10 seconds . The stored max imum speed is deleted.

Driver information display
- Turn the engine off.
- Check the engine oil level=>
page 284.
-Contact your authorized Audi dealer if necessary.
Engine oil level too low
If the engine oil level is too low, add engine oil=> page 284.
Engine oil level correct
If the symbol 't=7: flashes even though the engine oil level is correct,
please seek professional assistance . Do not continue driving . Do not
leave the engine running
idle, either.
(I] 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 intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication ... :lo requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning ~ starts to flash before you respond to the low oil
level warning . By then, your engine may already have suffered
serious damage. •

Warm and cold
(I] Tips
If the climate control is running in cooling mode, air flows mainly
from ve nts @ and @. To achieve adequate cooling, you should never
close these vents completely. •
Applies to vehicles: wit h deluxe auto mati c climate c ontro l
Economical use of the climate control
system
Economical use of the climate control system helps save
fuel.
When the climate control system is working in cooling mode,
engine performance is reduced and fuel consumption is
affected. To keep the time the climate control system is on as
short as possible, you should do the following :
- To save fuel, turn off cooling mode by pressing the [AC]
button (indicator light goes out).
- In addition, if you open the window while driving, turn off cooling mode by pressing the
[AC] button (indicator light
goes out).
- If the vehicle is extremely hot due to the heat of the sun,
briefly open doors and windows.
For the sake of the environment
When you save fuel, you reduce emissions from the vehicle. •
App lies to veh ic les: with del uxe automatic climate control
Automatic recirculation
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode.
The basic climate control settings can be adjusted in the
radio or
MMI*.
- Select: Function button [CAR]> Climate control switch.
We recommend that you always keep automatic recirculation ON to
prevent polluted outside ai r from entering the vehicle interior.
If the
air quality sensor located in the climate control system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the factory-installed pollutant filter or whether it is
necessary to switch to recirculation . With heavy concentrations of
pollutants, the climate control system is switched automatically to
recirculation mode and the supply of outside air is blocked . As soon
as the concentration of pollutants in the outside air drops, fresh air is
supplied to the vehicle interior again.
In the event tha t the windows fog up during au tomatic recircula tion,
press the[@] button immediately.
Under certain operating conditions, automatic recirculation is
switched off automatically. When outside temperatures are below
about SO
°F ( + 10 °(), automatic recirculation is limited to
30 seconds. When outside temperatures are below about 30
°F (-
1 °(), automatic recirculation is limited to 15 seconds .•
