On-Board Diagnostic system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunct ion Indicator Lamp (MIL) in the instrument cluster
=>
page 12, fig. 7 is part of the On-Board Diagnostic (OBD II) system.
Th e 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
whi le you are driving, a malfunction may exist in the engine system.
If the light illuminates, the catalytic converter could be damaged.
Continue driving
with reduced power (avoiding sustained high
speeds and/or rapid accelerat ions) and have the condition corrected.
Contact your authorized Aud i dealer .
If the light illuminates, the electronic speed limiter may also be
malfunction ing. For more information=>
page 22, "Electronic speed
limiter".
An improperly closed fuel filler cap may also cause the MIL light to
illuminate
=> page 2 76. •

Vehicle care Do-it-yourselt service iTechnical data

Driver information display
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 i llumi nates after a refueling , stop
the vehicle and make sure the fuel filler cap is properly closed
=> page 276.
In order to make an accurate diagnosis, the stored data can only be
displayed using special diagnostic equipment (generic scan too l 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
=> page 21, fig. 14.
Your authorized Audi dea ler or qualified workshop can interpret 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 veh icle. To reduce the risk of sudden t ire
fai lure 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 307.
If the engine control unit receives faulty vehicle road speed signals,
the Malfunction Ind icator Lamp (M IL) 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. •

(I) Tips
• Air circula tion helps to reduce window fogging. Sta le air escapes
to the outside thro ugh vents in the tr im panel. Be sure to keep these
slots free and ope n.
• Th e tire p ressure m ust co rrespon d to the load . The tire pressure is
show n on the tire p ressu re label. O n USA v ehicles, the tire p ress ure
label is located on the driver's side 8-p illar. On Canada veh icles, the
ti re pressu re lab el is locat ed either on the driver' s sid e B-pillar or
inside the fuel fi lle r flap . The t ire pressure labe l lists the recom ­
mended co ld tire in flati on press ures f or th e ve hicle at its max imum

I n a co llision, t he laws of physics mean that ev en sma ller items that
are loose i n the vehicle will become heavy missiles t hat can cause
serious injury. Items in the vehicle possess e nergy wh ich vary w ith
vehicle speed and the we ight of the item. Vehicle spee d is t he most
signifi cant factor.

ment Safety first Vehicle operation
For example,
in a frontal collis io n at a speed of 30 mph (48 km/ h),
t he forces a ctin g o n a 1 0-lb (4 .5 kg) objec t are ab out 20 times the
normal weight of the item . T his means that the weight of the item
wou ld s udden ly be abo ut 200 lbs . (90 kg). You can imagine the inju­
ries that a 200 lbs . (90 kg) item fly ing freely through the passenger
compartment could cause in a collision like this .
& WARNING
Weak, damaged or improper straps used to secure item s to tie­
downs can fail during hard braking or in a collision and cause
serious personal injury.
• Always use suitable mounting straps and properly secure items
to the tie -downs in the luggage compartment to help prevent
items from shifting or flying forward as dangerous missiles.
• When the rear seat backrest is folded down, always us e suit­
able mounting straps and properly secure items to the tie-downs
in the luggage compartment to help prevent items from flying
forward as dangerous missiles into the passenger compartment .
• Never attach a child safety seat tether strap to a tie-down .•

Blend of gasoline and MTBE
• Anti-knock index must be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform especially well for
winter or summer driving. During seasonal change-over, we suggest
that you fill up at busy gas stations where the seasonal adjustment is
more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may cause
corros ion and damage to plastic and rubber components in the fue l
system .
• Do not use fuels that fail to meet the specified criteria in this
chapter.
• If you are unab le to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
s u pplier.
• Do not use fue l for which the contents cannot be identified.
• Fuel system damage and performance problems resulting from
the use of fuels different from those specified are not the responsi ­
bility of Audi and are not covered under the New Vehicle or the Emis­
sion Control System Warranties.
• If you experience a loss of fuel economy or driveability and perfor­
mance problems due to the use of one of these fuel blends, we
recommend that you switch to unblended f uel. •
Gasoline additives
A major concern among many auto manufacturers is carbon depos it
build -up caused by the type of gasoline you use.
Safety first
Although gasoline grades differ from one manufacturer to another,
t hey have certain things in common. All gasoline grades contain
substances that can cause depos its to collect on v ital engi ne parts,
such as fuel injectors and intake valves. Although most gasoline
brands include additives to keep engine and fuel systems clean, they
are not equally effective .
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the officia l
webs ite (www.toptiergas.com).
After an extended per iod of using inadequate fuels, built-up carbon
deposits can rob your engine of peak performance .
