192 Cleaning and protection
-To a void damaging yo ur vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft
mater ials like rubber hoses, p lastic parts
and sound-deaden ing mater ials as well
as sensors and camera lenses . Never aim
the spray head at t he same po int for a
l ong time. This also app lies to cleaning
headlights and painted bumpers . Re­
member: the cl oser the nozzle is to the
su rface o f the materia l, the greater the
stress on the mate rial.
Caring for vehicles with matte finish
paint
Ap plies to vehicles: with matte finish pa int
Vehicles with matte finish point require spe­
cial core due to the characteristics of the

If the engine compartment is cleaned at any
time with grease removing solutions
1>, or if
you have the engine washed, the anti-corro­
sion 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 compartment .

Fuel recommendation
The fuel recomme nded for you r vehicle is un­
lead ed premium
g rade gasoline . See a lso
¢ pag e 263, Doto . Audi recommends usi ng
T OP TIER D eterge nt Gaso line wi th a mini mu m
octa ne ra tin g of 9 1 AKI (95 RON). For more
in fo rmation on TO P TI ER De tergent Gaso line,

Th e re commended g asoline oct ane r ating for
your engine can a lso be fo und on a label loca t­
e d on the ins ide of the fue l filler flap . This rat ­
ing may be specified as A KI or RO N.
Your veh icle m ay also be oper ated using un­
l ea ded regular g asoline with a min imum o c­
tane rating of 87 AKI/91 R ON. However, using
87 AKI/91 RON octa ne f ue l w ill slightly re ­
d uce eng ine perfo rmance.
Use unleaded gasoline only. Unleaded g aso­
line is availab le th rou gho ut the USA, Canada ,
and in most E uropean countries . We recom­
mend that you do not ta ke yo ur vehicle t o
areas or countries where unleaded gasoline
may not be avai lable.
F or mo re in format io n on refue ling your ve hi­

Octane rating
O cta ne r ating in dicates a gaso line's abili ty to
res ist engine damaging "knoc k" ca used by
p remature ign ition and detonation. Therefore,
buy ing the correct grade of gaso line is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the Unite d
States a nd Canada has the following octane r
at ings t hat can usu a lly be found on the fi ller
pump:
- Pre mium G ra de: 91 -9 6 A KI
- Regular Grade : 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti K nock Index= (R+M) /2 = (RO N
+ MON)/2
R ON= Resea rch Octane Numb er
MON = Motor Octane Num ber .
(D Note
-Do not use a ny f ue l w it h octane rat ings
lower tha n 87 A KI or 9 1 RO N othe rwise
expensiv e engine damage w ill occur.
- Do
not use leaded gasoline . The use of
lead ed gasoline w ill severely damage
yo ur v ehicl e's catalytic co nve rter a nd its
ability to co ntrol exha ust em ission s.
Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded g asoline blende d with
alcohol o r MTBE (commonly re ferred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index mus t be 87 A KI or higher.
- Blend must contain no mor e than 3% me th-
anol.
- Blend must contain more than 2% co-sol-
ve nts .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knoc k index must be 87 AKI or higher .
- Blend must not conta in mo re than 10%
ethanol.
Blend of ga soline and MTBE
- Anti-knoc k index must be 87 AKI or high er. ll-

-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 driving.
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 .
(D 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 fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- 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 responsibility 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.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
Fuel supply and filling your fuel tank 203
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.

208 Check ing and filling
- To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill flu ids on hot engine compo­
nents . They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electr ic fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam o r hot eng ine coolant by placing a
thi ck rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of burns.
- If wo rk on the fuel system or the electri­
c al system is necessa ry:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
pa rtment cou ld start a fire.
- Keep an approved fire extinguisher im­
mediately avai lable.
- To avoid electrical s hock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Othe r components of the high voltage
e lectronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- First, fully apply the parking bra ke,
