the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter . This
could result in overheating of the con
verter, requ iring its replacement.
- To assure efficient operation of the Emis
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec
ommendations in your Wa rranty
&
Ma intenan ce booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 161
fuel consumption by 10 -15 percent. Th is sec
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre
spond to your actual consumption on the road, which will vary depending upon vehi
cle load and speed, road and weather con
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less. Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maxi -
mum speed.
Acce lerat ing gently reduces fue l consump
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w il l
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con
ditions perm it.

Fuel supply
Using the right fuel helps keep the environ
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is un
lead ed premium
grade gasoline . See also
¢
page 240, Data . Audi recommends using
TOP TIER Detergent Gasoline with a minimum
octane rating of 91 AK I (95 RON). For more
information on TOP TI ER Detergent Gasoline,
p lease go to the officia l website (www.toptier
gas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat
ed on the inside of the fuel filler flap. This rat
ing may be specified as AKI or RON.
Your veh icle may also be operated using un
l eaded regular gasoline with a minimum oc
tane rating of 87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel wi ll slightly re
duce engine performance.
Use unleaded gasoline only. Unleaded gaso
line is available throughout the USA, Canada ,
and in most European countries . We recom
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
F or more information on refueling your vehi
cle, see¢
page 177.
Octane rating
Octane rating ind icates a gasoline's ability to
resist engine damaging "knock" caused by
premature ign ition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane r
atings that can usually be found on the fi ller
pump:
- Premium Grade: 91 -96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index= (R+M)/2 = (RON
+MON )/2
RON= Research Octane Number
MON = Motor Octane Number .
(D Note
-Do not use any fuel w ith octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage will occur.
- Do
not use leaded gasoline! The use of
leaded gasoline w ill severely damage
your vehicle'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
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knoc k index must be 87 A KI or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
-Anti -knock index must be 87 AKI or higher.
- Blend must not contain more than 10%
ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher. ll-
186 Checking and filling
on the hot engine and exhaust system
when the engine is running -fire hazard!
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
(D Note
- The oil level must not be above range 0
-danger of converter or engine damage!
Contact an authorized Audi dealer to
draw off oil, if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authori zed Audi dealer or a qualified serv
ice station .
Before you check anything in the engine com
partment,
always read and heed all WARN·
INGS
¢ & in Working in the engine compart
ment on page 180 .
The engine oil must be changed according to
the intervals specified in your Warranty &
Maintenance booklet. This is very important
because the lubricating properties of oil di
minish gradually during normal vehicle use .
Under some circumstances the engine oil
should be changed more frequently . Change
oil more often if you drive mostly short dis
tances , operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con
ditions, or have your vehicle where tempera
tures remain below freezing for extended pe riods. Detergent
additives in the oil will make fresh
oil look dark after the engine has been run
ning for a short time. This is normal and is not
a reason to change the oil more often than
recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station .
If you choose to change your oil yourself,
please note the following important informa
tion:
A WARNING
=
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help prevent hot oil from run
ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil off thoroughly
with soap and water.
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en
gine and adversely affect your Audi Limit
ed New Vehicle Warranty.
