You can switch between the trip computer 1 and 2 and the efficiency
program* by pressing the [
RESET] button@=> page 23, fig. 16.
You can tell which memory level is currently active by the number or
the sign in the display=> fig . 15. The data from the single-trip
memory (memory level 1) is being disp layed if a
1 appears in the
display. If a
2 is shown, then the data from the total-trip memory is
being disp layed (memory level 2). The fuel pump nozzle

the efficiency program*=>
page 24.
Single-trip memory (Trip computer 1)
The single-trip memory stores the trip information from the time the
ignition is turned on until it is turned off. If the tr ip is cont inued
within 2 hours from the time the ign ition was turned off, the new
data will be incl uded in the calculation of the current trip inf orma­
tion. If the trip is interrupted for
more than 2 hours the memory is
reset automa tically.
Total-trip memory (Trip computer 2)
Unlike the sing le-trip memory, the total-trip memory is not reset
automatically. This permits you to evaluate your driving data for the
entire period between manual resets.

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.

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=;,

(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 .•
