On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) in the instrument cluster
~ page 14, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
The warn ing/ind icator light illuminates when the ignition is switched
on and goes out after the engine starts and the idle has stabilized.
This indicat es 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 co nverter 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 29, "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
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 fue l
vapor recovery system. If the light illuminates after a refueling, stop
the vehicle and make sure the fuel filler cap is properly closed
=;, page 271 .
In order to make an accurate diagnosis, the stored data can only be
displayed using specia l diagnostic equipment (generic scan too l 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 hood release=;, fig. 22.
Your authorized Aud i dealer or qualified workshop can interpret the
code and perform the necessary repair. •
Electronic speed limiter
Your vehicle may be factory equ ipped with tires that are rated for a
maximum speed of 130 mph (210 km/h). This is less than the
maximum speed of your vehicle. To reduce the risk of sudden tire
failure and loss of contro l if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limite r. The elec­
tronic speed limiter prevents your vehicle from going faster than the
tire speed rating . For more information =;,
page 303.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Indicator Lamp (MIL) will illuminate . If this
occurs, contact the nearest authorized Audi dealer for ass istance. .,,_

Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 75 °F (+23 °C).
- Press the
[AUTO) button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting, as desired, to meet your personal needs.
Controls and equip­
ment Safety first
The climate controls are a combination
of heating, ventilation and
coo ling systems, which automatically red uce humidity and cool the
air inside your vehicle .
The climate control automatically maintains a temperature once it
has been set. The temperature of the air from the vents, fan speed
(air volume) and air distribution are also automatically adjusted. The
system a lso takes into account strong sunsh ine so that man ual
adjustment is not necessary. So in almost all cases,
automa tic mo de
offers the best condit ions for the comfort of the occupants at all
times of the year~

Please note the following:
T urn on the a ir cond itioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensati on from the evaporator may drip under the vehicle. This is
normal and does not indicate a leak .
If the outside temperature is low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently.
T he air conditioner temporari ly switches off when you drive off from
a standstill using full throttle to save engine power.
T he compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Du st a nd p ollen filt er
The dust and pollen filter (a combined particle fi lter and activated
charcoal filter) reduces or prevents outside a ir po llution (dust, or
pollen) from entering the vehicle.
T he dust and pollen filter must be changed at the intervals specified
in your Maintenance booklet, so that the air conditioner can properly
work.
If you drive your vehicle in an area with a high degree of air pollution,
the filter may need to be changed more frequently than specified in .,.

Automatic selector lever lock
The selector lever is locked in the P and N positions when the ignition
is turned on . To move the lever from these positions the driver must
depress the brake pedal. As a reminder to the driver, the following
warning appears in the instrument cluster display when the selector
is in
P and N:
When stationary apply footbrake while selecting gear
A time delay element prevents the selector lever from locking when
it is moved through the
N position (going from R to D). The locking
element will lock the selector lever if the lever is left in N (Neutral) for
more than approximately 1 second, without the brake pedal being
pressed .
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button on the selector lever prevents the lever from being
accidentally shifted into ce rtain positions. Pressing this button deac­
tivates the selector lever lock. Depending on the direction of the
shift, the selector lever locks at different positions . The positions are
highlighted in the illustration ~
page 153, fig. 147.

Kick-down
The kick-down feature allows the vehicle to generate
maximum acceleration.
When you press the accelerator pedal beyond the resistance point
that is reached at full throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine RPM . The engine RPM will be controlled to produce maximum vehicle acceleration as
long
as you continue to press the accelerator pedal beyond this resistance
point .
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •
Applies to ve hicles : with automatic t ransm iss ion
Dynamic shift program (DSP)
The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best shift program suited to the driving conditions and driving style .
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speed without heavy
acceleration . This achieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
The transmission will automatically select the
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds. Upshifts are delayed to make full use of
engine power . Downshifting takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable shift program is a continuous,
automatic process . The driver can also make the transmission switch
to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to achieve rapid acceleration, e.g. for quickly passing another vehicle. You do
not need to press the gas pedal into the kick -down range. After the
transmission has upshifted, the original program is selected
according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients.

Transmission Ill _______________ ___.
This keeps the transmission from shifting up and down unnecessarily
on hills . Th e transmission will shift down to a lower gear when the
driver presses the brake pedal on a downhill gradient . This makes use
of the braking effect of the engine without the need to shift down
manually .•

To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automat ica lly shift into the
next gear before the engine reaches its maximum RPM.
If you apply a light throttle when accelerating, tiptr onic will automat­
ically shift from 1st to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the dr iver sh ifts i nto 2nd gear.
If you take your foot off the accelerator pedal when driving down a
steep incline , tiptronic will downshift from the selected gear into the
next lower gear until it reaches 1st gear , based on road speed and
eng ine RPM. Automatic downshifting is interrupted as soon as you
apply the throttle again.
[ i ] Tips
• When you shif t into the next lower gear, the transmission will
downshift on ly when there is no possibility of over-revving the
engine.
• When the kick-down comes on, the transmission will shift down to
a lower gear, depending on vehicle and engine speeds.
• tiptronic is inoperative when the transmission is in the fail-safe
mode. •
