(D Note
Never run the tank completely dry! An irregu­
lar supply of fuel can cause engine misfiring
and fuel could enter into the exhaust system.
The catalytic converter could then overheat
and be damaged.

Driver information system
On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢• in the
instrument cluster is part of the On-Board Diag­
nostic (OBD II) system.
The warning/indicator light i lluminates when the
ignition is switched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates 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 illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid acce lerations)
and have the condition corrected. Contact your
authorized Audi dealer.
I f the light illuminates, the electronic speed lim­
iter may also be malfunctioning. For more infor­
mation
c::> page 28, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c::> page 192.
On-Board Diagnostics
Fig. 16 Loca tion of Data Link Connec tor (DLC)
On-Board Diagnostics monito rs the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code. In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory .
28
The MIL light may also illuminate if there is a
l eak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
c::> page 192.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using spec ia l diag­
nostic equipment (generic scan tool for 080).
In order to connect the specia l diagnostic equip ­
ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the r ight of the hood
release
c::> fig. 16.
Your authorized Audi dealer or qualified work­
shop can interpret the code and perform the nec­
essary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
Your vehicle may be factory equ ipped with tires
that are rated for a maximum speed of 130 mph
(210 km/h) . This is may be less than the maxi­
mum speed of your vehicle. To reduce the risk of
sudden tire failure and loss of control if the vehi ­
cle is operated at excessive speeds, your vehicle
has an e lectronic speed limiter. The electronic
speed limiter prevents your vehicle from going
faster than the tire speed rating. For more infor­
mation
c::> page 209.
-
If the engine contro l unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Light (MIL)
II will illuminate. If this occurs, con­
tact the nearest author ized Audi dealer for assis­
tance.
A WARNING
Always observe the posted speed lim its and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your
vehicle faster than the maximum speed rating
of the tires installed.

In the D/S position, the transmission can be oper­
ated either in the normal mode Dor in the sport
mode S . To select the sport mode S, pull these­
lector lever back brief ly. Pulling the lever back
again will se lect the normal mode D . The inst ru­
ment cluster display shows the selected driving
mode.
In the
normal mode D , the transmission auto­
matically selects the suitable gear ratio . It de­
pends on engine load, vehicle speed and driving
style.
Select the
sport mode S for sporty driving. The
vehicle makes full use of the engine 's power .
Shifting may become noticeable when accelerat­
ing.
When the vehicle is stationary or at speeds below 1 mph (2 km/h), you must a lways apply the foot
brake before and while moving the lever to D/S
out of N.
A WARNING
Read and follow all WARNINGS¢.&. in Driv­
ing the automatic transmission on
page 86.
(D Note
Coast ing downh ill with the transmission in N

Driving and th e environment
(D Tips
- Check the depth of the water before driving
through it.
- Do not stop the veh icle, drive in reverse or
switch the engine
off when driving through
water.
- Keep in mind that oncoming vehicles may
create waves that raise the water level and
make it too deep for your vehicle to dr ive
through safely.
- Avoid driving through sa lt water because it
can cause corrosion.
Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­ erly to ensure that your vehicle is running in an
environmentally sound manner .
~ Always use lead-free gasoline c:::;, page 190,
Fuel supply .
~ Never run the tank down a ll the way to empty .
~ Never put too much motor oil in your engine
c:::;, page 199, 9::?1 Adding engine oil .
~ Never try to push- or tow -start your veh icle.
The cata lytic conve rter is an eff icient "clean-up"
dev ice bu ilt into the exhaust system of the vehi­
cle. The cataly tic converter burns many of the
pollutants in the exhaust gas before they are re ­
leased into the atmosphere.
The ex clusive use of u nleaded fuel is critically im­
por tant for the life of the catalyt ic converte r and
p roper functioning o f the engine.
A WARNING ,..___ -
- The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust tail pipes once they
have become hot. This could result in burns.
- Do not park o r operate the vehicle in areas
whe re the hot exhaust system may come in
contact with dry grass, brush, fue l spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exha ust man i-
178
fold, exha ust pipes, catalytic converter or
heat shields. During driv ing, the substance
used for undercoat ing could overheat and
cause a f ire.
Cl) Note
- Be aware that just one tank fill ing with
le ad·
ed
fue l w ill already ser iously degrade the
performance of the catalytic converter.
- Do not exceed the correct engine oil level
c:::;,page 199.
-Do not drive until the fue l tank becomes
completely empty. The engine co uld m isfire.
Unburned fuel could also get into the ex­
haust system and this could cause the cata­
lyt ic converter to overheat.
- Do not turn
off the ignition while the vehicle
is moving .
- Do not continue to operate your veh icle un­
der these conditions, as otherwise fuel can
reach the catalytic converter . This could re­
sult in overheating of the conve rter, requ ir­
ing its replacement.
- T o assure efficient operation of the Emission
Cont ro l System:
- Have your vehicle maintained properly and
in accordance with the se rvice recommen­
dations in yo ur Warranty
& Maintenance
booklet.
- Lack of proper maintenance as we ll as im­
proper use of the vehicle will impair the
function of the emission control system
and could lead to damage.
(® For the sake of the environment
Even when the Emiss ion C ontrol System is op­
e rat ing proper ly, the exhaust gas can have a
sulfur-like exhaust gas sme ll under some op­
erat ing states. This depends on the sulfur
content of the fuel being used. Us ing a d iffe r­
ent brand of fue l may he lp, or fi llin g the tank
wi th lead-free s uper grade gaso line.
Shutting down vehicle
If you would like you r vehicle to remai n inope ra­
tive for a longer period of time, con tact an Audi
o r other spec ia liz ed dealer. They can adv ise you .,.

Driving and th e environment
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel .
.,. Have your vehicle serviced at regula r intervals.
By having your vehicle regularly serviced by an
authorized Audi dealer he lps to ensure that it
runs properly and economically. The condition of
your vehicle not only affects its safety and ability to hold its value, it also affects
f uel c onsump­
tion .
C he ck you r oil e ach t ime you fill you r ta nk .
The amount of oil used is related to engine load
and speed.
It is normal for the oil consumption of a new en­
g ine to reach its lowes t va lue after a cer tain mile ­
age has been d riven .
You must d rive you r vehicle about 3,000 miles
(5 ,000 k ilometers) before you can properly as­
sess o il cons umption .
This a lso applies to fuel consumption and engine
output.
(D Note
- Have your vehicle maintained properly and
in accordance w ith the service recommenda­
tions in you r Warra nty
& M aintenance book­
l et . Lack of p roper m aintenance as well as
i mprope r use of the vehicle will impair the
funct ion of the emission control system and
could lead to damage.
- Do not a lter or remove any component of
the Emission Cont ro l System unless ap­
proved by the manufacturer.
- Do not a lter o r remove any dev ice, such as
heat shie lds, switches, ignition wires,
va lves, which are designed to protect your
vehicle's Emiss ion Control System and other
i mportant veh icle components.

· Fewer short trips
Fuel consumption will always be relatively high
on short trips .
.,. Try to avoid dr iv ing short distances with a cold
eng ine .
The eng ine and catalytic converter have to reach
their opt imal
oper atin g temperature to reduce
fuel consumpt ion and noxious emissions effec­
tively .
Just after starting, a co ld engine in a mid-s ize car
on ly achieves a fuel economy of 6-8 mi les per
gallon (30-40 l/100 km). After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . After about
2.5 miles (4 km), the eng ine is
at its proper operating temperature and fuel
economy has reached a norma l level. So you can
see that you should avo id short trips whenever
poss ible .
The
out side t emp eratur e is also cr itical in th is re­
gard. Your car consumes more fuel in the winter
than in the summer.

Fuel and Refueling

Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­ mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine can also be found on a label located
on the ins ide of the fuel filler flap. This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­ ing of 87 AKl/91 RON . However, using 87 AKl/91
RON octane fue l will s lightly reduce eng ine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries. We recommend that
you do not take your vehicle to areas or countries
where unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 192.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade : 91 - 96 AKI
- Regular Grade: 87 -90 AKI
190
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
( methyl tertiary butyl ether)
You may use unleaded gasoline blended with a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knock index must be 87 AKI or h igher.
- Blend must not contain more than 1S% etha-
nol.
- Veh icles with flex ible fuel engine: blend must
not contain more than 85% ethanol.
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 es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-over, we suggest that you ""

Fuel and R efue lin g
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build- up ca used by the type
of gasoline you use.
Although gasoline grades differ from one manu­
facturer to another, they have certa in things in
common. All gaso line grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves. Al­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP T IER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the officia l website
(www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance .
CD Note
-Damage or ma lf u nction due to poor fuel
quality is not covered by the Aud i New Vehi­
cle Limited Warranty .
- Do not add aftermarket f uel addit ive prod­
ucts to your fuel tank.
Refueling
Fuel filler neck
The fuel f iller neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power Locking system should fail, you can
still open the flap manually -for deta iled instruc­
tions seer:>
page 194.
You can find the fue l tank capacity of your vehicle
in r:>
page 246 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle. For more in­
formation about fue l specifications, see
c:> page 190 .
Your vehicle fuel tank has an on -board refuelling
vapor recovery system . This feature helps to pre­
vent fuel vapors from escaping from the tank and
192
po lluting the environment while you refuel your
vehicle. In order to fi ll the tank properly while
protecting the environment, please follow this
refueling procedure carefu lly.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fuel can be dangerous. Such containers,
fu ll or empty, may leak and could ca use a fire
in a co llision.
If you must tra nsport f uel to
use for your lawn mower, snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fue l containers . Make cer­
tain the container meets industry standards (ANSI/ASTM F852 -86).
CD Note
Never drive your vehicle until the fue l tank is
complete ly empty. The irregular supply of
f u el can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.
