& WARNING
• Never rely exclusively on the outside temperature display to
determine if a road surface is icy or not. Keep in mind that road
surfaces, especially bridges and overpasses, could be ice covered
and slippery even at an outside temperature above 41 °F
1+5 °Cl.
• Always remember, even if the "snowflake" symbol lice
warning) does not appear in the display, black ice could be on the
road .
• Always reduce your speed and drive with special care in cold
weather conditions when the chance of encountering icy road
surfaces increases.
[ i ] Tips
When using the navigation system feature "Destination", the
outside temperature is also displayed.•
Miles (kilometers) to empty
The miles (kilometers) to empty indication is a valuable
aid to schedule the refueling stops on a trip.
Fig . 13 Center display:
miles (kilometers) to
empty
Th is feature shows you the estimated range in miles (kilometers)
:::::, fig. 13 until the tank runs dry. This feature calculates how far you
could drive with the amount of fuel left in your fuel tank while
driving under the current driving conditions. The remaining
distance is recalculated every
6 miles (10 km).
While calculating the miles (kilometers) to empty, the system also
calculates your fuel consumption over the last
18 miles (30 km).
Remember:
-the more economica lly you drive, the further you can
go.•
Warning : engine hood, door or rear lid open

On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL) (USA
models) / (Canada models)
The Malfunction Indicator Lamp (MIU in the instrument cluster
=> page 19, fig. 9 is part of the On -Board Diagnostic (OBD II) system.
The warning/indicator light il luminates when the ignition is
switched on and goes out after the engine starts and the idle has
stabi lized . This indicates that the MIL is working prope rly.
If the light do es 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
w ith redu ced pow er (avoiding sustained high
speeds and/or rapid accelerations) 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

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 305, "New tires and
r eplacing tires and wheels" .
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,
t he Malfunc tion Indicator Light (MIU will illuminate. If this occurs,
contact the nearest authorized Audi dea ler for ass istance.

cooling system malfunction likely to result in serious damage to the
engine. •
Engine oil pressure malfunction ~
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the 9=::;,. symbol appears in the display and blinks, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
Switch off engine, check oil level
Immediate actions
-Pull off the road and stop the vehicle.
-Shut the engine down.
-Check the engine oil level with the dipstick=> page 277.
Dipstick reading checks too lovv
-Top off oil to the proper level => page 278.
-Make sure that the oil pressure warning symbol 9=::;f.
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
-If the 9=::;f. symbol starts flashing again even though the
engine oil level checks OK on the dipstick,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis-
tance.
.,_

[ i J 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 interval s, 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 pre s­
s ure warning symbol
~ starts to fla sh before you respond to the
low oil level warning
-... . By then , your engine may already have
s uffered serious damage. •

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a
set speed limit.
Fig . 21 Disp lay : s pee d
wa rning syste m
.,.
irechnical data

Driver inf orma tion di spl ay
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 vehic le 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. 21 .
The speed warning system has
t wo wa rning thre sholds that func ­
tion independent ly of each other and that have somewhat different
purposes:
Sp eed w arnin g 1 -
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 (USA models)/ (: (Canada models) in
the warning 1 disp lay appears when you exceed the maximum
speed. It goes out when the speed falls be low 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 de leted.
Setting speed warning 1
~ page 36 .
S pee d w arni ng 2
Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a genera l maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, (USA models)/ (Canada models) appears in the disp lay when you exceed the stored speed limit .
Unlike warning 1, it wil l not go out until the vehicle speed drops
below the stored speed limit .
Setting speed warning 2
~ page 37.
[ i ] Tip s
Even though your vehicle is equipped with a speed warning system,
you shou ld still watch the speedometer to make sure you are not
driving faster than the speed l imit. •
