Service interval display
The service interval display detects when which service category is
required for your vehicle. It works in two stages:
• Service Reminder : Starting with a certain mileage before a
service event, this message appears when the ignition is switched
on:
SERVICE IN 5500 Ml 150 DAYS.
• Service Event:
If the due date for servicing has passed, the
message
SERVICE EXCEEDED! appears This message is accompa ­
nied by a warning signal. And the type of service needed is
displayed.
Checking the Remaining Distance
By briefly pulling the knob,=> fig. 13 -Arrow -, the remaining
distance and time to the next service schedule is displayed with the
ignition on . The distance remaining is updated every 300 miles (500

km). The next scheduled oil change and thereafter the next sched­
uled service will be displayed.
For new vehicles or after the vehicle has been serviced, the next
scheduled service will only be displayed after 300 miles (500 km)
have elapsed. Until this distance has been travelled, the display will
show
OIL CHANGE IN----- Ml ---DAYS and SERVICE IN----- Ml --­
DAYS.
To reset the display
The dealership performing the service resets the display when the service has been completed . You can reset the display in the instru ­
ment panel only if an oil change has been done. Proceed as follows:
• Switch the ignition on .
• Pull on button=> fig.
13 -Arrow-, and the following message
appears:
SERVICE EXCEEDED !.
• Keep pulling on the knob until OIL CHANGE IN ---- -Ml ---DAYS
appears in the display. If the reset button is not pulled within 5
seconds, the display reset mode closes.
[ i] Tips
• Do not reset the display between service intervals. Doing so will
result in an incorrect display.
• If service was not performed at the correct time or the service
interval display was not reset after service was performed, the addi ­
tional mileage driven or the elapsed days will be shown as negative
numbers.
• If the battery is disconnected, the Service Interval Display values
are retained.
• If a priority 1 malfunction is present (red symbol), the distance
remaining cannot be called up. •

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL )
The Malfunction Indicator Lamp (MIU in the instrument cluster
=:> page 16, fig. 6 is part of the On -Board Diagnos tic (OBD II) system.
The warning/indicator ligh t ill uminates 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 th e light d oes not go out after the engine is started, or illuminates
while you are driving, a ma lfunction may exist in the engine system.
If the light starts flashing, the catalytic converter cou ld be damaged .
Continue driving
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid acce lerations) 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 information=:>

( DL Cl
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
f ue l vapor recovery system. If the light i lluminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed

page 216.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l for
OBD).
In order to connect the special diagnostic equipment, push the plug
into the Data Link Connector (DLCl. The DLC is located to the right of
the hood release =:> fig . 14.
Your authorized Audi dealer or a qualified service station can inter ­
pret 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 vehicle. To reduce the risk of sudden tire
failure and loss of control if the vehicle is operated at excessive
speeds, your vehicle also has an electronic speed limiter . The elec­
tronic speed limiter prevents your vehic le from going faster than the
tire speed rating. For more in formation=:>
page 249.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fue l injectors. You will notice an immediate loss
of engine power and a drop in road speed .
If the engine control unit receives faulty vehicle roadspeed signals,
the Ma lfunction Indicator Light (MIU 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. •

warning system
Driver inform ation system
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed. A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 6 miles per hour (10 km/h). At the same time, a warning symbol appears in the
display=> fig. 23.
The speed warning system has
two warning thresholds that func ­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1 )f ..._ (Canada models)
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
J I ,.... (Canada models) 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 warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted .

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,

Storing tire pressures
Correct storage of specified pressure is the basic require­
ment for reliable tire pressure monitoring.
F ig . 29 S ET -butt on:
T ire pressure mon i­
t or ing syste m
In order for the tire pressure monitori ng system to operate
appropr iately, you have to re-save the specified p ressures
whenever you adjust tire pressures, for example when the load co nd ition of your vehicle changes. Proceed as fo llows:
Corr ecting tir e pr es sure
Check the pressure in the t ires.
- Adjust air pressure as needed to comply w ith the infor­
mat ion on the label located on the driver's side B -pillar
(visible when the door is open) .
Saving tire pressures
-Turn on the igniti on.
- Press the button :::> fig. 29 for app rox imately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three t imes .
All pressure warning indicators in the d isplay will be canceled. Following each intentional change in specified pressures, ti
re pres ­
sures must be resaved.
After the pressures are saved, the tire pressure monito ring system
measures the current tire pressures and saves them as the new
spec ified pressures .
[ i ] Tip s
• The tire pressure is shown on the tire pressure labe l. The tire
pressur e lab el is located on the driv er's sid e B-pillar (visible when
the door is open). The tire pressure label l ists the recommended
cold tir e inflation pr essur es for the vehic le at its maximum capacity
weigh t and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for norma l load
conditions, please see chapter~
page 242.
• The tire pressure monitoring syst em he lps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the cor rect tire pressure .•
