A WARNING
-
Improper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l 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
fuel 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
fueling . The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle white 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 e lectricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open f lame any­
where in or near your veh icle when refu­
eling or filling a portab le fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable

fuel container in your vehicle. The con­
tainer, full or empty may leak and co uld
cause a fire, especially in a crash.
- If, under exceptional circumstances, yo u
must transport a portable fuel container,
please observe the following:
- Never fi ll a po rtable fue l container
while it is anywhe re in or on the vehicle
(for examp le, in the luggage compar t­
ment, or on the tr unk). Static electric i­
ty can bui ld up while fi lling and can ig­
n ite fue l vapors causing a fire .
- Always p lace a portable fuel container
on the gro und before filling.
- Always keep the fi ller nozzle comp lete­
ly inside the po rtable conta iner before
and during filling.
- If filling a portable container made of
metal, the filler nozz le must always be
in contact with the container. Th is w ill
he lp prevent static electricity from dis­
charging and cause a fi re .
- Never sp ill fuel inside the vehicle or
luggage compartment. Fue l vapors are
h ighly f lammable .
- Always observe local and state/provin­
cial laws regard ing the use, storage
and tra nsporta tion of fuel co ntainers .
- Make certai n the fuel container meets
industry standards (ANSI/ ASTM
F 8 52 -86) .
(D Note
If any f uel has spilled onto t he car, it
should be removed immediate ly to prevent
damage to the paint.
~ For the sake of the environment
As soon as the correctly operated nozzle sw itches off automatically fo r the fi rst
time, the tank is full. Do not try to add more fue l because fue l may spill out . In
add it io n, th e expans io n sp ace in the fuel
t ank will be fi lled -cau sin g the fue l to

@ Tips
- Ru nning your eng ine whi le refue lli ng
may cause vapors to escape or even
cause fuel to sp ill out of the tank. T his
would then shut off the fuel nozzle be­
f o re the ta nk is f ull.
- Do not refuel you r vehicle with the ign i­
tion turned o n. The fuel gauge may oth­
erwise not indicate the correct f uel level
after refuelling .
- The fue l filler flap of yo ur vehicle is not
locked when you lock t he ve hicle from

238 Check ing and filling
- Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine coo l down . Hot
components will burn skin on contact.
- To reduce the risk o f 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 or hot eng ine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
-If work on the fuel system or the electri­
cal system is necessary :
- A lways disconnect the battery.
- Never smo ke or work near heaters or
open flames . Fluids in the engine com ­
partment co uld start a fire.
- Keep an approved fire ext inguisher im­
mediately available.
- T o avoid ele ctrical shock and persona l in ­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r l ever o f automat ic trans- mission to
"P" (Park); put manua l
transmission in Neutra l.
- Always use extreme caution to p revent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wea r clothing that
will hang o r droop into the engine.
- M inim ize exposure to em iss ion and
chemical hazards

age to vehicle systems w ill occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regular ly. If
you see spots from oil or o ther ve hicle flu­
i ds, have your vehicle insp ected by a n au­
thorized Audi dealer.

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il

nance and use requ irements as set forth in
the Audi Owner's Manua l and Warranty
&
Maintenance book let . Your dea ler will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
wa s pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle dep ends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective l ubrication and
cool ing of i nternal engine components, a ll in­
ternal comb ustion eng ines consume a cert ain
amo unt of o il. Oil cons umption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in per iod (see
c::;, page 213) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under norma l conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the amb ient
temperature and road condit ions. Furthe r fac­
tors ar e the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is s ubje ct to
Checkin g and fillin g 241
wear as m ileage builds up, the oil consump ­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
Ill in the instrument cluster lights up, yo u
sho uld check the oil leve l as soon as possib le

(D Note
D riving w ith a n insufficient o il level is like­
ly to cause sever e damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals , pref­
erably each time you refuel, and alway s
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes ex ce ssive amoun ts of o il, we
recommend that you consul t an a uthor­
ized Aud i dea ler to have the cause of
your concern properly d iagnosed. Keep in
mind that the accurate measu rement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil co nsumption accurately.

Tread
means that portion of a tire that comes into
contact with the road.
Tread separation
means pull ing away of the tread from the tire
carcass .
Treadwear indicators (TWI)
means the projections within the principal
grooves designed to give a visual indication of
the degrees of wear of the tread. See
c:> page 262, Tread Wear Indicator (TWI) for
more informat ion on measuring tir e wear.
Uniform Tire Quality Grading
is a tire information system developed by the
United States National Highway Traffic Safety
Administration (NHTSA) that is designed to help buyers make relative comparisons among
tires. The UTQG is not a safety rating and not a
guaran tee that a tire will last for a prescribed
number of miles (kilometers) or perform in a
certain way.
It simply gives tire buyers addi ­
tional information to combine with other con ­
siderat ions, such as pr ice, brand loya lty and
dealer recommendations. Under UTQG, tires
are graded by the tire manufacturers in three
areas: treadwear, traction, and temperature
res istance . The UTQG information on the tires,
mo lded into the sid ewa lls.
U.S . DOT Tire Identification Number (TIN)
This is the t ire's "serial number". It begins
with the letters "DOT" and indicates that the tire
meets all federal standards. The next two
numbers or letters indicate the plant where it
was man ufactured, and the last four numbers
represent the week and year of man ufacture.
For example,
DOT . .. 2209 ...
means tha t the tire was produced in the 22nd
week of 2009. The other numbers are market­
ing codes that may or may not be used by the
tire manufacturer . This information is used to
contact consumers if a tire defect requires a
recall.
Vehicle capacity weight
means the rated cargo and luggage load plus
150 lbs.
(68 kilograms) times the vehicle's to­
ta l seating capacity as listed on the label lo­
cated either on the driver's side B-pillar or on
the inside of the fuel filler flap.
Vehicle maximum load on the tire
means that load on an individua l tir e that is
determined by distributing to each ax le its
share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individua l tir e that is
determined by distributing to each axle its
share of the curb weight, accessory weight,
and normal occupant weight (distributed in
accordance with tab le below
c:> page 255)
and dividing by two.

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 210 Tire p ress ure labe l: loca ted e ith er on d river 's
side 8 -pillar or ins ide t he fue l filler flap
Tire pressure genera lly refers to the amount
of air i n a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the inte rna­
tional measuring unit and in pounds pe r
squa re inch ( PSI). Tire pressure is based in
pa rt o n the vehicle's design an d load limit­
the greatest amount of weight that the vehi ­
cle can carry safe ly and the t ire size . The prop­
er tire pressure is freq uently referred to as the
"recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ress ure is higher when the tire
h as warmed up than when i t is "cold ." It is the
in flat ion pressu re i n a "cold " tire that coun ts.
T herefore, you sho uld neve r let air ou t of a
warm tire to match " co ld tir e infla tion pres­
sure" recommendations . The ti res wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr es su re is one o f the
most impor tan t things you can do to he lp
avoid sudden tire failure. Underinfla ted ti res
a re a major ca use of s udden tire failure. Keep­
ing tires at the r ight pressure is also impor­
tant for safe and responsive vehicle handling,
traction, braking and load carrying .
Tire pres­
sur es are particularly important when th e
vehicle is being driven at higher speeds , and
then especially when heav ily loaded even
w ithin the permissible load -carrying capaci ­
tie s approved for y our vehicle .

and the numbe r of passengers and/or amount
of luggage you w il l be transporting .
On USA vehicles, the t ire pressure label is lo­
cated on the driver's side B-p illar. On Canada
vehicles, the tire press ure label is located ei­
ther on the dr iver's s ide B-pillar or inside the
fuel fille r flap. The t ire press ure l abel lists the

If you wish to improve comfort when operat­
ing the vehicle at normal load (up to 3 oc cu­
pant s), you can adjust tire pre ssures to those
specified for normal vehicle lo ad. Before op­
erating the vehicle at maximum load, you
must increase the ti re pressures to those
