Th e catalyt ic conve rter is an eff ic ient "clean-up" device built into the
ex ha ust system of the vehicle . The catalytic converter burns many of
t he pollu tan ts i n the exhaust gas be fore they are re leased into the
atmosphere.
Th e excl usive use o f un leaded fuel is crit ic all y import ant for the lif e of
the catalytic converter and proper funct io ni ng of the engine.
& WARNING
• Do not park or ope rate the vehicle in areas where the hot
exhaust sy stem may come in conta ct with dry grass, bru sh, fuel
spill or othe r materi al which can cause a fire .
• Do not apply additional undercoating or rustproofing on or
near the exhaust manifold , exhaust p ipes , catalytic converter or
heat shi eld s. During driving, the sub stance u sed for und ercoating
could o verheat and cause a fire.
0 Note
• Be aware that just one tank filling w it h leaded fuel will already
ser iously degr ade the performance of the catalyt ic converter.
• Do not exceed the correct engine oi l level =>
page 284.
• Do not dr ive until t he fuel tank becomes com plete ly em pty. The
engine could misfire. Unbu rned fue l co uld also get into the exhaust
sys tem and t his co ul d cause t he ca talyt ic converter to ove rheat.
• Do not turn off the ignition while the vehicle is moving.
• Do not continue to operate your vehicle under these conditions, as
otherwise fuel can reac h the cata lyti c conve rter. This co ul d res ult in
over heat ing of the converter, requir ing its rep lacement.

~ For the sake of the environment
Even when the Emiss ion Contro l System is operating properly, the
exhaust gas can have a s ulfur-like exhaust gas smell under some
operating states . This depends on the sulfur content of the fue l being
used. Using a differe nt brand of fuel may help, or filli ng the tank with
lead-free super g rade gasoline. •
Operate your vehicle economically
and minimize pollution
General
Yo ur p ersonal sty le o f driving will determine the eco nom y
of your vehicle, as well as exhaust and noise levels .
Fuel economy, envi ronmenta l impact, and wear on your engine,
bra kes and tires la rgely depend on t hree fac to rs:
• your persona l dr iv ing style
• operati ng conditio ns
• technical limitations
If you an tici pat e wh at yo u nee d to do nex t an d drive eco no m ic ally,
you can easily cut your fuel consumpt io n by 10-15 percent. This

Driving and environment
(I] Tip s
The consumption estimates as pub lished by ENV IRONMENTAL
PROTECTION AGENCY (EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary
depending upon vehicle load and speed, road and weather conditions,
trip length, etc. •
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are accelerating .
-Avo id unnecessary accelerating and braking.
Vehicles use the most fue l when they a re accele rating. If you antici­
pate what is going to happen next, you will need to brake less and,
thus, accelerate less. Let the vehicle coast whenever possible -for
example when you see that the next traffic l ight is red. •
Avoid full throttle
Driving at moderate speeds saves fuel and improves your
mileage.
- Try and keep well below your car's maximum speed .
Accelerating gently reduces fuel consumption, engine wear, and does
not disturb the environment.
Fuel consumption, exhaust emissions and engine noise increase
disproportionately at high speeds . If you drive at approx imately three
qua rters of top speed, fuel consumption will be reduced by one half.
Never drive faster than the posted speed limit and weather condi­
tions permit.
a Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
-
Shut the engine off when yo u are not driving the vehicle.
- Do not warm up the vehic le by letting the eng ine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting for
trains to pass at rai lroad crossings, o r at traffic lights that have long
wa its on red . Turn ing the eng ine off for just 30-40 seconds saves
more fuel than is burned starting the engine again.
It takes a long t ime for the engine to warm up fully when it is running
at idle. Howeve r, wear and noxious emissions are espec ially high
when the eng ine is wa rm ing up. So you sho uld d rive away as soon as
you start the engine and avoid running at hig h rpms while the eng ine
is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would go
unheeded. Extended idling also produces heat, which cou ld result in
overheat ing o r othe r damage to the vehicle or other p roperty. •
Regular maintenanc_e ____________ _
A badly tuned engine unnecessarily wastes a lot of fuel .
- Have your vehicle serviced at regular intervals .
By having yo ur vehicle regularly se rviced by an Audi dealer helps to
ensure that it runs properly and economically . T he condition of your
vehicle not only a ffects its safety and ability to ho ld its va lue, it a lso
affects
fu el con sumption .
Check your o il e ach tim e you fill you r tank.

Driving and environment
------------------------------------------------'
The amount of oil used is related to engine load and speed.
It is normal for the oil consumption of a new engine to reach its
lowest value after a certain mileage has been driven .
You must drive your vehicle about 3,000 miles (5,000 kilometers)
before you can properly assess oil consumption.
This also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with the
service recommendations in your Warranty
& Maintenance booklet.
Lack of proper maintenance as well as improper use of the vehicle w ill
impair the function of the emission control system and cou ld lead to
damage.
• Do not alter or remove any component of the Emission Control
System un less approved by the manufacturer.
• Do not a lter or remove any device, such as heat shie lds, switches,
ignition wires, valves, which are designed to protect your vehicle's Emission Contro l System and other important vehicle components. •
Fewer short trips
Fuel consumption will always be relatively high on short
trips .
-Try to avoid driving short distances with a cold engine.
The eng ine and catalytic converter have to reach thei r optima l oper­
ating temperature
to reduce fuel consumption and noxio us em is­
sions effectively.
Just after starting, a cold engine in a mid -size car only achieves a fuel
economy of 6-8 miles per gallon (30-40 l/l00km). After about a half
a mile, fuel economy climbs to 12 mpg (20 l/100 km). After about
2.5 miles (4 km), the engine is at its proper operating temperature
Controls and equip­
ment Safety first Vehicle operation
and fuel economy has
reached a normal level. So you can see that you
should avoid short trips whenever possible.
The
outside temperature is also cr it ical in th is regard . Your car
consumes more fuel in the winter than in the summer. •

Trailer towing
"---------------------------------------------------
Speed
T he higher the speed, the more difficult it becomes for the driver to
control the rig. Do not dr ive at the max imum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icu larly when go ing downhill.
Reduce vehicle speed
immediately if the tra iler shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for veh icles towing
trailers are lower than for regu lar vehicles.
Always apply brakes early. When driv ing dow nhill, shift in to a lower
gear to use the eng ine braking effect to slow the veh icle. Use of the
bra kes alone can cause them to overheat and fail.
Coolant temperature
Th e coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
_f_ , pull off the road, stop and let the engine idle for
about two m inutes to prevent heat build-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi.•
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a trailer because of the
additiona l weight and different weight distribution. Safety, perfor- mance and economy will greatly depend on how carefully you load
your trailer and operate your rig.
Before you actually tow your trailer, practice turning, stopp ing and
backing up in an area away from traffic. Keep practicing until you have
become completely familiar with the way your vehicle-t railer comb i­
nation behaves and responds.
Backing up is difficult and requires practice. Backing up with a trailer
generally requires steering action oppos ite to that when backing up
your vehicle without a trai ler.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop. To compensate for the
trailer, you will need a larger than normal turning radius .
When passing, remember that you cannot accelerate as fast as you normally would because of the added load . Make sure you have
enoug h room to pass. After passing, allow plenty of room for your
trai ler before changing lanes again.
Avoid jerky sta rts, sharp tur ns or rapid lane changes.
W Tips
• Do not tow a trailer during the break-in per iod of your veh icle.
• If you tow a trai ler, your Audi may require more frequent mainte­
nance due to the extra load
~ page 346. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
- Apply the foot brake.
- Have someone p lace chocks under both the vehicle and the
trailer wheels . ._

Fuel supply and filling your fuel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is unleaded premium grade
g asoline . See also :::>
page 343, "D ata ". Aud i recommends using TO P
TIER Detergent Gasoline with a minimum octane ra ting of 91 AKI (95
R O N). For more information on TOP TIE R Detergen t Gasoline, please
go to the official website (www. toptiergas .com) .
Th e recommended gasoline octane rating for your engine can also be
found on a labe l located on the ins ide of t he fue l fille r flap. This rating
may be specified as AKI or RON .
Your vehicle may also be ope rated us ing unleaded reg ular gasoline
with a minim um octane rating of 87 AKI/91 RON. However, us ing 87
AKI/91 RON octane fuel will slig htly reduce engine performance.
Use un leaded ga soline only. U nleaded gaso line is available
throughout the USA, Canada, and in most E uropean co untries. We
recommen d that you do not ta ke your veh icle to areas or co unt ries
where unleaded gasoline may not be available.
F or more in formation on re fueling yo ur vehicle, see:::>
page 274 .
Octane rating
Octane r ati ng indi cat es a gaso line's abi lity to resis t engi ne damag ing
"knock" caused by premature ignition and detonat ion. Therefore,
buying the correc t g rade o f gasol ine is very impo rtan t to help preve nt
possible engine damage and a loss of engine performance .
Gaso line most common ly used in the United States and Canada has
the following octa ne rat ings tha t ca n usually be fou nd on the filler
pump :
Safety first
• Premium Grade: 91 - 96 AKI
• Regular Grade: 87 - 90 AKI
Explanation of t he abb reviations :
AKI= Anti Knock Index= (R +M)/2 = (RON+ MON)/2
RO N= Research Octane Number
M ON= M otor Octane Num ber.
0 Note
• Do not use any fue l with octane rat ings lower than 87 AKI o r 91
RO N otherwise expens ive engine damage will occ ur.
• Do
not use leaded gasoline. The use of lea ded gasoline w ill
severely damage your veh icle 's cata lytic converter and its abi lity to
cont rol exhaust emissions .•
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl
tertiary butyl ether)
Yo u may use unleaded gasoline blended w ith alcoho l or MTBE
( c ommon ly referred to as oxygenates) if the blended mix ture meets
the following criteria:
Blend of ga soline methanol (wood alcohol or methyl alcohol)
• Anti -k nock index m ust be 87 AKI or h igher .
• Bl end must con tain no mo re t han 3% methanol.
• Blend must contain more than 2% co-solvents.
Blend of ga soline and ethanol (grain alcohol or ethyl alcohol)
• Anti-knock index must be 87 AKI o r higher.
• Bl end must no t contain more th an 10% ethanol.
