Instruments and warning/indicator lights 17
o Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (M IL) is part
of the On-Board Diagnostic (OBD II) system.
The symbol
f• lights up when the ignition is
turned on and will turn off after the engine
has started and has sett led at a constant idle
speed. Th is ind icates that the MIL is working
properly.
The warning light illuminates when there is a
malfunction in the engine electronic system .
Contact your author ized Audi dealer and have
the ma lfunction corrected.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate (only vehi­
cles with gasoline engine)

0 Adaptive Air Suspension
Applies to vehicles: with Adaptive Air Suspension
This II warning/indicator light has the fol­
l owing functions:
- It illuminates for a few seconds after the ig­
nition is turned on as function check and
then goes out .
- If the warning/ind icator light illuminates or
blinks continuously, there is a system fau lt
in the Adaptive A ir Suspension . A system
fault can result in limited ride comfort and
low ground clearance . Drive safely to the
nearest authorized Aud i dealer or qualified
workshop, and have the fault corrected .
- If the warning/ind icator light flashes, you
should not drive the vehicle. The flash ing
warning/ind icator light po ints to an extreme
High level. A very
pronounced lifting of the
vehicle (extreme High level) can resu lt, fo r
example, when a heavy load is removed
from the vehicle. As soon as the leve l has re­
turned to normal, the warning/indicator
light stops flashing, and you can drive away.
- If the warning/ind icator light flashes in con­
junction with the
II warning/indicator
light, you sho uld not drive off immediately
i n order to prevent damage to the under­
body. The two warning/ind icator lights flashing together points to an extreme Low
level. A very
pronounced lowering of the ve­
hicle (extreme Low leve l) can result, for ex­
ample, from a heavy load. As soon as the
level has retu rned to normal, the warning/
ind icator lights stop flashing, and you can
drive away.
(D Note
If the warning/indicator light flashes in
conjunction with the
II warni ng/indica­
tor light, you should not dr ive the veh icle
because low-lying vehicle parts can bot­
tom out as you drive over uneven ground
and be damaged as a result.

This II warning/ indicator light has the fol ­
lowing functions:
- It illuminates for a few seconds after the ig­
nition is turned on as function check and
then goes out.
- It comes on for approximately 15 seconds
as a warning of
reduced ground clearance , if
the dynamic mode is activated and if the ig­
nition is switched on

controls.
- If the warning/indicator light flashes in con­
junction with the
II warning/indicator
light, you should not drive the vehicle imme­
diately in order to prevent damage to the
underbody. The two warn ing/ indicator
lights flashing together points to an ex­
treme Low level. A very
pronounced lower­
ing
of the vehicle (extreme Low level) can re­
sult, for example, from a heavy load. As
soon as the level has returned to normal,
the warning/indicator lights stop flashing,
and you can drive away.

On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in
the instrument cluster¢
page 14, fig. 8 is
part of the On-Board Diagnos tic (OBD II) sys­
tem .
The warning/indicator light ill um inates when
the ignition is switched on and goes out after
the engine star ts and the id le has stabilized.
This indicates that the M IL is working prope r­
ly .
If the light does not go out after the engine
is started , or illuminates while you are dr iv­
ing, a malfunction may exist in the engine sys ­
tem . If the light illuminates, the catalytic con­
verter could b e damaged .
Con tinue driving
with reduced powe r (avoid­
ing s ustained high speeds and/or rapid accel ­
erations) and have the cond ition co rrected .
Contact your a uthorized Aud i dea ler.
If the light illum inates, the electronic speed
limiter may also be malfunctioning . For more
information ¢

On-Board Diagnostics monitors the compo­
nents of your emission control system. Each
monitored component in your engine system
has been assigned a code . In case of a mal­
function, the component will be ident ified
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 sys­
tem.
If the light illuminates after a refuelling ,
stop the veh icle and make sure the fuel filler
cap is proper ly closed (on ly vehicles with gaso­
line engine)

Do not use the diagnostic connector for
personal use. Incorrect usage can cause
ma lfunctions, which can increase the risk
of a collis ion!
Electronic speed
limiter
Your vehicle may be factory equipped w ith
t ir es 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 fa ilure a nd loss of contro l if
the vehicle is operated at excessive speeds,
your vehicle also has an elec tronic speed limit­
er . The e lectronic speed limiter prevents your
vehicle from going faster than the tire speed
rating . For more information ¢
page 285.
If the engine control unit receives faulty vehi­
cle roadspeed signals, the Malfunction Indica ­
tor Lamp (MIL)
II will ill uminate. If this oc­
curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING
-
Always observe the posted speed limits
and adjust your speed to suit prevailing
road, traffic and weather cond itions . Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.

Speed warning system
Overview
The speed warning system helps you to keep
your driving speed below a set speed limit.
T he speed warning system warns the driver if
he exceeds a previo usly stored maximum
speed . A warning tone wi ll so und as soon as
the vehicle speed exceeds the set speed by about 3 mph (3 km/h). At the same time, a
warning symbol appears in the display.
The speed warning system has
two warning
thresholds
that function independently of
each other and that have somewhat different
purposes:
Speed warning 1
You can use speed warning 1 to set the maxi­
mum speed while you are driving. This setting "'

252 Fuel supply and filling your fuel tank
Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fue l filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No. 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
Diesel fuel has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter. It is also norma l when whitish-blue
smoke comes out of the tailpipe after starting
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your Diese l engine idle unnecessari ­
ly after a cold start. Driving off slowly will
shorten the warm-up period.
A WARNING
- Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in ser ious engine damage and per­
sonal injur y.
- Never use fuel line anti-freeze offered for
gasoline engines.
(D Note
- Your Diesel engine has been specifically designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasoline. The
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
cause expensive engine repairs and will
also adversely affect your New Vehicle
Limited Warranty.
- If Diesel fuel sho uld get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not allow D iesel fuel to remain on connect­
ing hoses . They may develop leaks and
cause serious damage.

You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 316 .
The label on the inside of the fuel filler flap
te lls you the correct fuel for your vehicle. For
more information about fuel specifications,
see ¢
page 250.
Your vehicle fuel tank has an on-board refuel­
ling vapo r recovery system. This feature helps
to prevent fue l vapors from escaping from the
