Information from the Driver Information System is shown in the
display in the cen ter of the instrument clust er.
When you turn on the ignition and while you are driving, some func ­
tions and vehicle components are scanned for their operating status. Malfunctions or required service procedures are signalled
audibly and shown by red and yellow ligh ted symbols and
reminders to the driver in the display.
The driver is also shown information about radio and CD operation and directions fo r the navigation system . You can find additional
information on these subjects in the MMI manual.

rized Audi Service department. •
Service interval display
The service interval display reminds you when your next
service is due.
Fig. 14 Display:
Service interval display
The date for service is calculated automatically. Based on the
average distance driven in previous months, a monthly driv ing
distance is calculated . As soon as the distance remaining to the next
service drops below the distance driven monthly, the service
reminder is initiated. The maximum period from one service to the
next is one year.
Service reminder
30 days b efore the next service is due, a service reminder appears
in the display when you turn on the ignition => fig. 14.
Contro ls and eq uip­
ment
Driver information display
After about 5 seconds the display switches back to normal. The
distance and time remaining are updated each time the ignition is
turned on until the date due for service is reached .
Service
When the due date for service is reached, the message Service due
! appears in the display immediately after you turn on the ignition.
Additionally, a warning tone sounds . After about 5 seconds the
display switches back to normal.
0 Note
If you disconnect the battery terminals, no calculations can be
made for the service interval display during this time and no service
reminder will appear . Remember that observing the proper service
intervals is vitally important to extending the life of your vehicle,
particularly the engine, and maintaining its value . Even if the
mileage driven is low, the maximum period of one year from one
service to the next must not be exceeded. •
On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (Mill in the instrument cluster
=>
page 16, 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 starts flashing , 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 author ized Audi dealer .
Vehicle care I I irechnical data

Driver information display
If the light illuminates, the electronic speed limiter may also be
malfunctioning. For more information~
page 28, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
~ page 305. •
On-Board Diagnostics
Fig. 15 Location of
Data Link Connector
(DLCl
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
fuel vapor recovery system. If the light illuminates after a refuelling,
stop the vehicle and make sure the fuel filler cap is properly closed
~ page 305.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic 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 hood release
~ fig. 15. 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 vehicle from going faster than the
tire speed rating. For more information ~
page 338.
If the vehicle approaches the tire speed rating, the engine control
unit will turn off the fuel injectors. You will notice an immediate loss
of engine power and a drop in road speed.
If the engine control unit receives faulty vehicle road speed signals ,
the Malfunction Indicator Lamp (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. •
Auto Check Control
Introduction
The Auto -Check control monitors the function of certain vehicle
features and components. It simply makes sure these features and
components are working properly . The Auto -Check control works as
long as the ignition is on, as well as whenever the vehicle is driven .....

Driver information display
-Pull off the road.
- Stop the veh icle.
- Turn off the engine.

page 317.
-Add coolant if necessary ~ page 318.
-Continue dr iving only after the eng ine coolant
warning/ indicator light goes out .
- Contact your authorized Audi dealer for assistance if
necessary .
If the engine coolant le ve l is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
~ page 18, 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 73, "Emer­
gency flasher

the engine and allow it to cool. Follow the warning stickers
~ page 301, "Engine compartment".
0 Note

malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction "t=:?:
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low -oil -pres ­
sure indication is likely to inflict severe damage to the
engine.

pressure is too low. An additional driver message can also
be displayed by pressing the
I CHECK] button:
Switch off engine and check oil level
Immediate actions

appears no longer in the display before you start driving
again. .,,,

Dipstick reading checks OK
-If the oil pressure warning symbol "t=:7: starts flashing
again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[ 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 .: 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. •
