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 (MIU -in the instrument cluster
=> page 17, 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 authorized Audi dealer.
If the light illuminates , the electronic speed limiter may also be
malfunctioning . For more information =>
page 30, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 293. •

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

Driver information display
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 information=>
page 325.
If the vehicle approaches the tire speed rating, the engine control
unit wi ll 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, traffi c 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.
If a component is malfunctioning or if the need for an urgent repair
has been detected, this will appear in the instrument c luster display. You will
also hear an audible warning tone. The disp lays are co lor
coded in either red or yel low depending on their level of priority.
A red symbol means Danger , a yellow symbol indicates Warning . In
certain situations, information message for the driver appear in
addition to the red and yellow symbols.
Function test: automatic transmission
The Auto-Check Control will automatically perform a test each time
you switch on the ignition. With the selector lever in
P or N, the
following message appears in the display:
When stationary apply footbrake while selecting gear.
When you a se lect a different gear (for example: R, D , etc.l, the
message will disappear and the Auto-Check function is displayed.
If there is a malfunction, then the malfunction message wi ll appear
about 15 seconds after the you start the vehic le. At the same time
you will hear a warning tone .•

mil eage
The fol lowing driving information is continuously evaluated by the
t rip computer and can be displayed sequential ly in the instrument
cluster display.
Fuel r ang e
The estimated cruising range in miles (km) appears in the display.
This tells you how far your vehicle will be able to trave l on the
current tank of fuel and with the same driving sty le. The display
changes in increments of 6 miles (10 km).
The cruising range is ca lculated based on the fuel consumption for
the last 18 miles (30 km). If you drive conservatively, the cruising
range will increase .
Avera ge fu el mil eage
The average fuel economy in MPG (1/100 km) since you last cleared
the memory appears in this display. You can use this display to
adjust your driving technique to achieve a desired mileage.
C urr en t fu el mi leage
The instantaneous fuel consumption in m iles per gallon (1/ 100 km)
is shown in this disp lay. You can use this display to adjust your
driving technique to achieve a desired mileage .
Fuel consumption is recalculated at interva ls of 33 yards (30
meters) . When the vehicle is stationary, the most recent fuel
consumption is displayed .

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 significantly
under-inflated . The TPMS on ly provides a low tire pressure warning
and does not reinflate your tires .
Accordingly, when the low tire pressure telltale illumin ates, you
should stop and check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a significantly under ­
inflated tire causes the tire to overheat and can lead to tire failure.
Under -inflation also reduces fuel efficiency and tire tread life, and
may affect the vehicle's handling and stopping ability .
0 Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's responsibility 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 inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation pres­ sure label. (I f your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehicle has also been equipped with a TPMS malfunction indi ­
cator to indicate when the system is not operating properly . The
TPMS malfunction indicator is combined with the low t ire pressure
telltale. When the system detects a ma lfunction, the te lltale wi ll
flash for approximately one minute and then remain continuously il luminated . T his sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists.
When the malfunction indicator is illuminated, the system may not be ab le to detect or signa l low tire pressure as intended.
TPMS ma lfunctions may occur for a variety of reasons, including the
installation of replacement or alternate tires or wheels on the
veh ic le that prevent the TPMS from functioning proper ly . Always
check the TPMS malfunction telltale after replacing one or more
tires or whee ls on your ve hicle to ensure t hat the replacement or
a lternate tires and wheels a llow the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitoring system senses a significant
loss of air pressure in one or severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to a lert the driver .
Controls and equip ­
ment
Dr ive r informat ion di spl ay
The , J warning light in the instrument cluster comes on when the
t ire is significantly underinflated
~ page 20 .
The warning light I also i lluminates in the case of a system
malfunction.
Be aware that t ire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres ­
sure increases by about 1 .5 psi (0 .1 bar). The tire warms up while the
vehicle is moving and tire pressure rises . So you should adjust tire
pressure on ly when they are
cold, when the tempera ture of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all four tires should be checked at regular
intervals, adjusted if necessary and saved in the proper setting
(recommended pressure) ~
page 45.
The tire pressure is shown on the label located either on the driver's
s ide 8 -pi llar (visible when the door is open) or inside the fue l filler
flap .
& WARNING
• Wh en the tire pre ssure mon itor ing system warning light i s lit,

Driver inf ormati on displ ay
<£> For th e sak e of th e environm ent
Driving w ith under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tip s
• Each tire, incl udin g the sp are, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 317.
• The factory supplied spare whee l is equipped with a sensor for
the tire pressure monitoring system. As long as the spare whee l it
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system he lps the driver to keep an
eye on t ire pressures. But the driver stil l has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature .
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged. Only the valve core needs to be rep laced
and, i f necessary, the valve and the wheel electronics replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire p ressure monitoring system.
Otherwise the system w ill register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres­
sure monitor ing system to the load you are carry ing. •
