2009 AUDI S6 service indicator

On-Board Diagnostic system (08D)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIU ~ in the instrument cluster
~ page 16, fig. 7 is part of the On-Board Diagnostic (OBD ID system.
The warning/indicator light illuminates 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 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 27, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
~ page 297. •
On-Board Diagnostics

Driver information display
On-Board Diagnostics monitors the components of your emission
control system. Each monitored component in your engine sys tem
has been assigned a code. In case of a malfunction, the component
wil l be identified and the fault stored as a code in the control
module memory .
The M IL 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 297.
In order to make an accurate diagnosis, the stored data can only be
d isplayed using special diagnostic equipment (generic scan tool for
OBDl.
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. 16.
Your authorized Audi dealer or a qua lified 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 329.
If the engine control unit receives faulty vehicle roadspeed signa ls,
the Malfunction Indicator Lamp (MIU will i lluminate . If this
occurs, contact the nearest authorized Audi dealer for assistance. .,.
Vehicle care I I Technical data

Driver information display
Engine oil pressure malfunction "t=;f':
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.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also
be displayed by pressing the
!CHECK] button:
Switch off engine and check oil level
Immediate actions
- Pull off the road.
- Stop the vehicle.
- Turn off the engine.
-Check the engine oil level with the dipstick=:> page 305.
Dipstick readings checks too low
-Top off oil to the proper level ::::, page 306.
Make sure that the oil pressure warning symbol~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol~ 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. •
Steering malfunction i
If there is a malfunction in the electronic steering column
lock, the steering cannot be unlocked.
If the i symbol in the display blinks, there is a malfunction
in the electronic steering column lock. An additional driver
message can also be displayed by pressing the
I CHECK]
button:
Do not drive vehicle: Steering defective
-Contact your nearest authorized repair facility.
- Do
not tow your vehicle.
& WARNING
Your vehicle must not be towed in the event of a malfunction in the
electronic steering column lock because it cannot be steered due
to the locked steering. If it is towed with the steering locked, there
is the risk of an accident. •

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
The speed warning system warns the driver if he exceeds a previ ­
ous ly stored maximum speed. A warning tone will sound as soon as
the vehicle speed exceeds th e set speed by about 3 mph (3 km/h). At
the same t ime, a warning symbol appears in the display .
The speed warning system has
t w o wa rnin g thr eshol ds that func­
tion independent ly of each other and that have somewhat different
purposes:
S peed warnin 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 se tting .
The speed warning symbol
0 (USA models) /0 (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 wi ll also go out if the speed
e xce eds the
stored maximum speed by more than about 25 mph
(40 km/h) for at
leas t 1 O seconds. The stored maximum speed is deleted .

Tire pr essure
Inco rrect tire pressure causes prematu re wear and can cau se
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month
~ page 323 .
Driving style
Dr iv ing fa st around curves, heavy acceleration and hard brak ing
increase tire wear.
Rotating tire s for more even wear
For all four t ires on your vehic le to have the same service life, we
recommend that the front and rea r tires are rotat ed acc ord ing to the
tire manufacturer 's suggested tire rotation intervals. Please
remembe r the f ollo wi ng :
• Tire rotat ion i nterva ls m ay d iffer from the vehic le serv ice inte r­
vals outl ined in your Maintenance and Warranty Book let.
• The longer one tire is used in one location on the vehicle, t he
more it wears at certain points; the refo re, we recommend that you
f ollow the tire manu facturer's sug ges ted t ire rotat ion i nte rvals.
• Vehicles with fro nt-w hee l dr ive e xper ience more tread wear on
the front wheels compared to all -wheel drive (quattro®l .
• Please rotate tires as sh ow n~
page 32 7, fig. 250 .
• Extra care must be taken when rotating direction -specific tires

page 268.
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly ,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds .
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control . •
