Cleaning and protec tion 213
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignit ion before clean ­
ing the engine
¢ .& .
Plenum panel
Remove leaves from the plenum panel in front
of the windshield under the engin e compart­
ment . This prevents the water drain holes
from becoming b locked , and it preve nts de­
bris from entering the vehicle interio r through
the heat ing and ventilat ion ducts .
Corrosion protection
The eng in e compartm ent and transmission
have been corrosion-protected at the facto ry .
Good anti -corrosion treatment is very impor ­
tant , partic ularly in the w inte r.
If the vehicle
is frequently d riven on salt treated roads, th e
entire engine compartment and p lenum panel
shou ld be thoroughly cleaned at the end of
winter a nd retreated to p revent salt damage .
At the same time, the unde rside of the vehicle
shou ld be washed as well.
If the engine compar tment is cleaned at any
time with grease remov ing solutions
1> , or if
you have the engine washed, the ant i-corro­
s io n treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng cor rosion pro tect ion rea pplied to all
s u rfaces , seams, joints and components in the
engine compartment .
A WARNING
Be aware: The engine com partment of any
motor veh icle is a potentially hazardous
area.
- Before work ing in the engine compart­
ment, be sure to read the information
¢ page 219 .

214 Cleaning and protec tio n
- Before reaching into the front pane l, al­
ways switch off the ignition. Otherwise,
the windshield wiper system could un in­
tent ionally be switched on, possib ly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan is temperature controlled and can switch
on suddenly- even when the ignit ion is
off.
- Do not wash, wax or d ry the engine w ith
the engine running. Moving or ho t pa rts
cou ld inju re you .
- Do not clean the underside of the chas­
sis, fenders , wheel cove rs, or other hard
to reach parts w ithout protecting your
hands and arms . You may cut yourse lf on
sharp-edged metal parts.
- Always read and heed all WARNINGS and other information

216 Fuel supply and filling your fuel tank
-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driv ing.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time.
(CT) Note
- Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fuels that fai l to meet the
specified criteria in this chapter.
- If yo u are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel sup plier.
- Do not use fuel 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 respons ibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac ­
turers is carbon deposit build- up caused by
the type of gasoline you use.
A lthough gasoline grades differ from one
manufacturer to another, they have certain
things in common. All gasoline g rades contain
substances that can cause deposits to co llect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and fuel
systems clean, they a re not equally effec­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
f uels, carbon deposit build-ups can rob yo ur
engine of peak performance.

Damage or malf u nct ion due to poor fuel
quality is not covered by the Aud i New Ve­
hicle Limited Warranty.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
s ide panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually- for detailed
instructions see
¢page 218.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢ page 278.
The label on the inside of the fuel fi ller flap
tells you the correct fue l for your veh icle. For
more information about fuel specifications,
see
¢ page 215.
Your vehicle fuel tank has an on board refuel­ li ng vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly wh ile protecting the environment,
please fo llow this refueling procedure careful­
ly.
.8, WARNING
Under normal operating cond itions, never
carry additional fuel containers in your car.
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must

transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F8S2 -86) .
@ Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalyt ic converter.

A 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 refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fue l to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can
cause a fire.
- Never use a cellular telephone while re­
fue ling. The electromagnet ic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling.

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
-
The engine in your Audi is a sophisticated
powerp lant that was built to exacting specifi­
cations . This engine needs the r ight kind of
engine o il that meets spec ificat ions regarding
qua lity and viscos ity so that it can run
smoothly and reliably . Choos ing the righ t oi l
and changing oil within the time and mileage
interva ls printed in your vehicle 's Warranty
&
Maintenance book let matters a lot more to­
day than it did years ago. Audi has developed
a special quality standard for engine oil that
will help assure that your veh icle's eng ine will
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast trad itional petrole -u
m -based oils, making them a smart choice
for use throughout the life of your Audi.
Whether you use synthet ic o r petro le um­
based eng ine oil, the oi l that you use m ust
conform to Audi's oi l quality standard
VW 502 00 to help keep your vehicle's engine runn ing smooth ly and help prevent the for­
mation of harmfu l deposits, sometimes called
"sludge," that over time can lead to expensive
repairs.
At the time of printing, engine oils ava ilable in
the U.S. and Canada that meet the exacting
specifications of Audi oil standard VW 502 00
are synthet ic eng ine oils . Th is does not mean,
howeve r, that every synthetic engine oil will
meet Audi o il standard VW 502 00 . So always
be su re that you use an approved oil.
To help prevent the formation of harmfu l de ­
pos its use only o il w ith the following specifi­
cations pr inted on the o il conta iner:
Audi oil standard VW 502 00
Oil container labels may carry the specifica­
tion sing ly or in combination with other desig ­
nations and oil quality standards.
V is cos ity
Engine o ils are graded a ccord ing to their vis­
cosity . The proper vis cos ity grade oil fo r yo ur
engine depends on climactic or seasona l con­
ditions where you drive. You can use oil with a
viscosity grade of SAE 5W40 across a ll tem­
perature ranges for norma l driving conditions.
However, if engine oil v iscosity g rade SA E
SW40 is not available , you can also use viscos ­
ity grade SAE SW-30 or SAE OW-40 as long as
it meets Audi oil qua lity standard VW 502 00
specifications.
Beca use engine oi l that meets the Audi oil
standard may not be availab le everywhere
when you need it, we strong ly recommend
that you a lways carry with you an extra quart
( li ter) of oil that express ly conforms to the
VW 502 00 spec ificat ion, in case you have to
top off the o il while o n the road . ..,_

224 Check ing and filling
With all these variab les coming in to p lay, no
standard rate of oil consumption can b e es­
tablished or specif ied. There is no alternative
to regular and frequent checking of the oi l lev­
el, see
Note .
If the ye llow engin e oi l level warning symbol
