long waits on red. Turning the engine off for just 30 -40 seconds
saves more f ue l than i s bu rned star ting the engine again.
It takes a long time for the engine to warm up fully when it is
running at idle. However , wear and noxious em issions are especial ly
h ig h w hen the eng ine is warming up. So y ou should dr ive away as
soon as you start the engine and avoid running at high RPMs whi le
the eng ine is still warming up.
0 Note
Do not leave en gine idling unattended after starting. If warn ing
lights should come on to indicate improper operation, they would
go unheeded . Extended idling also produces heat, wh ich cou ld
result in overheating or other damage to the vehicle or other
property .
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehicle serviced at regu lar intervals.
By having your vehicle regu lar ly serviced by an authorized Audi
dea ler he lps to ensure that it runs properly and econo mically . The
condition of your vehicle not only affects its safety and abi lity to
hold i ts va lue, it a lso affects fuel consumpt ion .
Che ck yo ur oil ea ch t ime you fill your t ank.
T he amount of oil used is related to engine load and speed.
It is nor mal for the oil consumption of a new engine to reach its
lowest va lue after a certain mi leage has been driven.
You must drive your vehicle about 3,000 mi les (5,000 kilometers)
before you can proper ly assess oil consumption .
T his 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 we ll as improper use of the
vehic le wi ll 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 unless approved by the manufacturer .
• Do not alter or remove any device, such as heat shields,
sw itches, ignition wires, valves, which are designed to protect your
vehic le's Emission Control System and other important vehicle
components. •
Fewer short trips
Fuel consump tion will always be relatively hi gh on shor t
trips.
- Try to avo id driving short dista nces wi th a cold en gine.
The engine and cata lytic c onverter have to reach their optima l oper ­
ating temperature to reduce fuel consumption and noxious emis ­
sions effective ly .
• Just after starting, a cold engine in a mid-size car burns the fuel
at a poor rate of 6 -8 miles per gallon (30 -40 11100km). Half a mi le
down the road, the mileage improves to 12 MPG (20 1/100 km). It wi ll
take the engine no less than
two and a half miles (4 km) of driving to
warm up to its proper operat ing temperature and operate at a n
economic mileage . This exp lains why taking the car for short trips is
a ra ther waste ful convenience .
• The outs ide temperat ure is also critical in this regard. Your car
consumes more fuel in the winter than in the summer .•

Care of exterior
Washing
F requent washing protects the vehicle.
The best protection against environmental influences is frequent
washing a nd waxing.
How often this is required depends on :
• How much the vehicle is used
• Where the vehicle is parked (garage, in the open under trees ,
etc.)
• The seasonal and weather conditions
• Environmenta l influences
The longer bird droppings, insects, tree resin, road and industrial
gri me, tar, soot, road salt and other materials remain on the vehicle
body , the more lasting their destructive effects will be. .,_

Cleaning and protection -

•
Safety belts
Only well-maintained safety belts work reliably when
needed.
-Keep belts clean.
- For cleaning, use a mild soap and water solution. Let
belts dry thoroughly and away from direct sunlight.
- Do not allow inertia reel safety belts to retract before
they are completely dry.
- Check the condition of your safety belts
regularly.
Heavily soiled safety belts may not retract properly.
& WARNING
Damaged safety belts can break in a crash .
• Anything that might damage your safety belts could mean that
you and your passengers would not be adequately protected in an
accident.
• Safety belt performance depends on correct installation. Never
remove belts from the vehicle to clean them .
• Do not use chemical cleaning agents, bleach or dyes. They have
corrosive properties which weaken the webbing.
• When cleaning your safety belts, inspect them for damage. If
you discover damage, see your authorized Audi dealer.
• Always read and heed all WARNINGS and other information
=:, page 204. •
Engine compartment
Be especially careful when cleaning the engine compart­
ment.
Always switch off the ignition before cleaning the engine =:> &.
Plenum panel
Remove leaves from the plenum panel in front of the windshield
under the engine hood. This prevents the water drain holes from
becoming blocked, and it prevents debris from entering the vehicle
interior through the heating and ventilation ducts .
Corrosion protection
The engine compartment and transmission have been corrosion­
protected at the factory.
Good anti-corrosion treatment is very important, particularly in the
winter. If the vehicle is frequently driven on salt treated roads, the
entire engine compartment and plenum panel should be thor ­
oughly cleaned at the end of winter and retreated to prevent salt
damage. At the same time, the underside of the vehicle should be
washed as well.
If the engine compartment is cleaned at any time with grease
removing solutions
3l, or if you have the engine washed , the anti­
corrosion treatment is almost always removed as well . It is therefore
essential to have a long-lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the engine compart ­
ment.
& WARNING
Be aware: The engine compartment of any motor vehicle is a
potentially hazardous area.
• Before working in the engine compartment, be sure to read the
information
=:> page 215 . .,_
31 Use only the correct cleaning solutions. Never use gasoline or diesel fuel.

Fuel supply and filling your fuel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environment clean and
prevents engine damage.
Fuel r ecomm end ati on
The fuel recommended for your vehic le is unl eade d prem ium grade
gaso line . See also ~
page 296, "Data". Audi recommends using TOP
T IER Detergent Gasoline with a minimum octane rating of 91 AKI (95
RON). For more information on TOP TIER Detergent Gaso line, please
go to the official website (www.toptiergas .com).
The recommended gasoline octane rating for your engine can also be found on a label located on the inside of the fuel fille r flap. This
rating may be specified as AK I or RON .
Your vehic le may also be operated us ing unleaded regular gasoline
with a minimum octane rating of 87 AKl/91 RON . However, using 87
AKl/9 1 RON octane fuel will slightly reduce engine performance.
Use unle ad ed ga so line only . Unleaded gaso line is avai lable
throughout the USA, Canada, and in most European countries. We
recommend that you do not take your vehicle to areas or countr ies
where un leaded gasoline may not be available .
For more information on refueling your vehicle, see~
page 219 .
Octane ra tin g
Octane rating indicates a gaso line's ability to resist engine
damaging "knock" caused by premature ignition and detonation.
Therefore, buying the correct grade of gaso line is very important to
help prevent possible engine damage and a loss of engine perfor ­
mance. Gasoline most common
ly used in the United States and Canada has
the following octane ratings that can usua lly be found on the filler
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 = M otor Octane Number .
0 Note
• Do not use any fue l with 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 will
severe ly damage your vehicle's catalytic converter and its abi lity to
control exhaust emissions. •
Blended gasoline
Use of g aso line containing alco hol or M TB E ( meth yl
t er tiary butyl e ther )
You may use unleaded gasoline blended with alcohol or MTBE
(commonly referred to as oxygenates) if the blended mixture meets
the follow ing criteria:
Bl end of g asoline m eth anol (wood al coho l or methyl alc oh ol)
• Anti-knock index must be 87 AKI or higher .
• Blend must contain no more than 3% methanol.
• Blend must contain more than 2% co-solvents.
Vehicle care I t •

Fuel supply and filling your fu el tank
Blend of g asoline and ethanol (grain al cohol or ethyl alcoho l}
• Anti -knock index must be 87 A KI or higher.
• Blend must not contain more than 10% ethanol.
Blend of gasoline and MTBE
• Anti -knock index mus t be 87 AKI or higher.
• Blend must contain not more than 15% MTBE.
Seasonally adjusted ga sol ine
Many gaso line grades are blended to perform especia lly wel l for
winter or summer d rivi ng. During seasona l 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 fue ls which do not meet these requirements may
cause corrosion and damage to plastic and rubber components in
the fue l system.
• Do not use fuels that fail to meet the specif ied criteria in this
chapter .
• If you are unable to determine whether or not a particu lar fuel
blend meets the specifications, ask your service station or its fuel
supplier.
• Do n ot use fuel for w hich the con tents cann ot be iden tified.
• Fuel system damage and performance p rob lems resulting from
th e use of fuels d ifferen t from those speci fied a re not the resp onsi ­
bility of Audi and are not covered under the New Vehicle or the
E mi ssion Contr ol System Warran tie s.
• If you experience a loss of fue l economy or driveabi lity and
performance p ro blems due to t he use of o ne of these fuel blends,
we recommend that you switch to unblended fuel. •
Gasoline additives
A major concern among many auto manufacturers is carbon
d epos it build -up caused by the type of gasol ine y ou use.
A lthough gasoline grades differ from one manufacturer to another,
t hey have certain things in common . A ll gas oline g rades co ntain
substances that can cause deposits to collect on vital engine parts,
such as fue l injectors and intake valves. A lthough most gaso line
brands include additives to keep eng ine and fue l systems clean,
they are not equal ly effective .
Audi reco mmends using TOP TIER De tergent Gasol ine. F or mo re
information on TOP TIER Detergent Gasoline, p lease go to the offi ­
cia l websi te (www.t optie rgas .co m).
A ft er an extended period of usin g inadequate fuels, bui lt -up carbon
depos its can rob you r engine of peak pe rformance .

Applies to vehicles: with diese l e ngi ne
Diesel fuel
Alwa ys use ULS D (Ultr a Low Sulfur D ie sel) s ulfur con te n t
15 ppm or less.
T he ULSD (Ultra Low Sulfur Diesel) meets the AS TM -D -975 (grade 2l.
Diesel fuel with a higher concentration than ULSD -Diesel No . 2
ASTM D975 and Bio -diesel with a h igher concentration than 5 % like
B11 , B20 or B100 are strictly prohibited.
Serv ice station fuel pu mps are labeled with the correct fuel in fo rma ­
tion for easy recognition by the user. If the diese l fue l pump is not .,_

•
labeled ask the station operator what fuel is being dispensed before
filling up your vehic le .
Service stations offering diesel fuel are generally located on truck
routes or major highways. Directories of diesel fuel stations are
usually available at diese l fuel stations.
Some states in the USA require permits to purchase diesel fuel.
Check with your State Motor Vehicle Department.
Diesel fuel may not be available outside the USA and Canada . Be
su re to check before traveling to other countries .
Winte r ope ra ti on
At temperatures be low 20° F (- 7° Cl, Diesel fuel No. 2 loses its fluidity
due to wax separation, which may c log the fuel filter or tank filter
and keep the engine from running.
To he lp the filter from being clogged by wax, the fue l filter in your
vehic le is automatically preheated. Preheating the fuel fi lter makes
operation of your vehicle poss ible with Diese l fue l No. 2 down to -
10° F (- 24° Cl.
If you expect tempe ratures below 5° F ( -15° C) ask your fuel dealer
whether their Diesel fuel No. 2 is sufficiently winterized for the prevai ling and expected temperatures .
If not winterized or insufficiently winterized diesel fuel has already
thickened to the extent that the engine will not start, warm the
vehicle up by leaving it in a heated garage.
It is normal that the engine noise level (dieseling) is louder during
the warm -up per iod in winter. It is also normal when whitish -blue
smoke comes out of the tailpipe after starting and dur ing warm-up.
The amount of smoke depends on the outside temperature .
Do not let your diese l eng ine idle unnecessarily after a cold start.
Driving off slowly will shorten the warm -up period.

& WARNING
Improper refueling or handling of fuel can cause fire , explosion
and severe burns .
• Fuel is highly flammable and can cause severe burns and other
injuries .
• Failure to shut the engine off while refueling and /or to insert
the pump nozzle fully into the fuel filler ne ck could cause fuel to
spray out of filler neck or to overflow. Fuel spray and overflowing
fuel can cause a fire .
• Never use a cellular telephone while refueling . The electromag ­
netic radiation can cause sparks that can ignite fuel vapors and
c ause a fire .
• Never get ba ck into your vehicle while refueling .
If in excep­
tional circumstances you must get back in your vehicle while refu ­
eling , make certain that you close the door and touch metal to
discharge static electricity before touching the filler nozzle again.
& WARNING (continued )
Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety, we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container , full or
empty may leak and could cause a fire , especially in a crash .
• If, under e xceptional circumstances , you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere in or
on the vehicle (for example , in the luggage compartment , or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors cau sing a fire.
- Always place a portable fuel container on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling .
- If filling a portable container made of metal , the filler nozzle
must always be in contact with the container. This will help
prevent static electricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are h ighly flammable.
- Alway s observe local and state /provincial laws regarding the
use , storage and transportation of fuel containers.
- Make certain the fuel container meets industry standards
