-Apply the parking brake.
- Move selector lever to P (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk 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 fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal 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 repair
with the engine running:

- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
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 wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING

- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
Q) Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur .

Using the proper engine oil is important for
the functionality and service life of the en­
g ine. Your engine was factory -filled with a
h igh-quality oil which can usually be used
t h roughout the entire year.
Your Limited New Vehicle Warranty does not cover damage or ma lf u nctions due to
fa ilure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet .
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
sta ndard specified for your veh icle's e n­
gine . U sing any other oil can cause seri­
ous eng ine dam age.
- Do not m ix any l ubrica nts o r othe r addi­
tives into the eng ine oi l. Doing so can
ca use eng ine damage.
I f you need to add oil and there is no ne
availab le tha t mee ts the Audi o il qua lity
s t andard your engine requires, yo u may
add a tota l of no more than 0 .5 quart/ liter
of a high -quality "synthetic"oil t hat meets
the following specifications.
- Vehicles with gaso line engine: ACEA A3
or API S M with a viscosity grade of
SAE OW-30, SAE SW-30 or SA E SW-40.
- Vehicles with diesel engine: ACEA C3 o r
API CF with a v iscosity grade of
SAE OW-30 or SAE SW-30.

Eng ine oil consumption
To provide effect ive lub rication and cooling for
internal engine pa rts, all inte rnal combust ion
engines use some oil. Oil consumption varies
Checkin g and fillin g 259
from engine to engine and may change ove r
the life of the engine. Engines tend to use
more o il during the break-in period than they
do afterward, when o il cons umption has sta­
bili zed. Depending on the way the vehicle is
driven and the operati ng conditions, oil con ­
sumption can be up to 1 quart per 1,200
mil es(! lite r per 2,000 km) . Consumption
may be higher wi thin the fi rs t 3,000 m iles
(5,000 km) .
Un der normal cond itions, the rate of oil con­
sumption depends on o il quality as well as v is­
cosity, engine speed (rpm), outs ide tempera­
ture, road condi tions, the amount of oil d il u ­
t ion caused by condensed water or fue l resi­
due, and oxidation of the oi l. Oi l consump tion
may inc rease with engine wear over time, un ­
ti l replacement of worn engine parts may be ­
come necessary.
Beca use of all these variables, there is no
standard or "norma l" rate of o il cons umption .
We urge you to check the engine oil le vel at
regular intervals, p referably e very time you
fill the fuel tank, and always before a long
trip .
The oil p ressure wa rning light. is not an
indicato r of low engine oil le vel. If the wa rn ­
ing light does not go out after starting, or
flash es while dri ving (above 1500 rpm ), a
buzzer will sound . It indicates that the oil
pres sure is too low. Stop the engine immedi­
ately, che ck the engine oil level and add oil if
n ec ess ary. If the engine oil level i s normal,
but the light continues to flash , do not keep
driving or let the engine idle, as dam age may
occur .
If you believe yo ur engine uses too much o il,
we recommend that you consul t your author ­
ized Audi dea ler so that the ca use of yo ur con­
cern can be proper ly diagnosed . Keep in mind
that acc urate measurement of oil consump­
tion req uires great care and may take some
time . Your Audi dealer h as ins truc tions for
how to measure oil consumption accurately .

War ra nty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soi l.
- Observe and follow legal regulations
when disposing of empty oil containers .
· Changing the engine oil
Engine oil must be changed at intervals listed
in the Warranty
& Maintenance booklet.
T he eng ine oi l and oil fi lter m ust be changed
accord ing to the mileage and time intervals
specified in yo ur vehicle's Warranty
& Mainte­
nance booklet. Do not exceed these intervals -
harmful s ludge and deposits from old engine
o il can reduce engine performance and can
lead to expens ive engine repa irs .
Changing oi l at reg ular intervals is so very im­
portant because the lubricat ing properties of
o il decrease gradually during normal vehicle
use. If you are not sure when to have the oil
c h anged, ask your authorized Audi Serv ice Ad­
viso r.
Under some circumstances the engine oil
shou ld eve n be changed more often than
spec ified for normal use. Change o il more of­
ten if you often dr ive short d istances , operate
the ve hicl e in dusty a reas or mostly under
stop- and-go t raffic conditions, or when you
use your veh icle where temperatures stay be ­
l ow freezing point for long periods.
Dete rgent additives in the oil will make fres h
o il look dark after the engine has been ru n­
ning for a sho rt time. This is normal and is not
a reaso n to change the oil more often than
recommended.

- Drain the oi l into a container designed
for this pu rpose, one large enough to
hold at least the total amount of oil in
your engine.
- To reduce the risk of poisoning, never use
empty food or beverage containers that
might m islead someone into dr ink ing
from them.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Cont inuous contact with used engine oil
is harmful to your skin. Always protect
your sk in by washing thoroughly with
soap and water .
(D Note
Never mix oil additives with your engine
oil. These additives can damage your en­
gine and adverse ly affect your Audi Limit­
ed New Vehicle Warranty.
@i For the sake of the environment
- Before changing the oil, first make sure
you know where you can properly dispose of the old oil.

contact a service station.
- We strongly recommend that yo u have
your oil changed by an authorized Audi
dealer or a qualified workshop with the
special tools and expert ise required, and
proper means of disposal.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
T he cooling sys tem is sealed and genera lly re­
quires little attention.
The cooling system has been fi lled at the fac­
tory with a permanent coolant which does not need to be changed. The coo lant cons ists of a
mixtu re of specially conditioned water and the
manufacturer's g lycol -basedcoo la nt add
i-
tive G l3 antifreeze with anticorrosion addi ­
tives (SO% for USA mode ls; 60% for Canadian
models). This mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the eng ine's cooling system from
corros ion and scaling.
It also ra ises the bo il­
i ng po int of the coolant .
Do not reduce the concentration of the cool­
ant in the summer by adding p lain wate r. Th e
proportion of coo lant additiv e mu st be at
l e as t 50 °/4 but not m ore than 60°/4
to main­
ta in ant ifreeze protect io n and cooling eff ic ien­
c y.
If the coo lant fros t protection is too low,
the coolant could freeze and damage the vehi­
cle heating and engine cooling system.
For year- round driving, antifreeze is added at
t h e factory fo r temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) Canada.

264 Check ing and filling
Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system
or hot eng ine parts. Under certain condi­
t io ns, the ethy lene g lycol in engine cool­
an t ca n ca tch f ire.
0 Note
Do not add any type of radiator leak seal­
ant to your vehicle's eng ine coolant. Add­
ing radiato r repair fluid may adve rsely af­
fect the function and performance of your
cooling system and could res ult in damage
not covered by your New Vehicle Limited
Warranty .

Avoiding damage
If you have to drive over a curb
or similar obstacle , drive very
slowly and as close as possible
at a right angle to the curb.
Always keep chemicals includ­ ing grease, oil, gasoline and
brake fluid off the tires.
Inspect the t ires regularly for
damage (cuts, cracks or blis­
ters, etc.). Remove any foreign bodies embedded in the treads.
Storing tires
Mark tires when you remove
them to indicate the direction
of rotation. This ensures you to be able to mount them correct­
ly when you reinstall them.
When removed, the wheels or
tires should be stored in a cool, dry and preferably dark place.
Store tires in a vertical position if they are not mounted on
rims, in a horizontal position if
they are mounted on rims.

Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash .
Your safety and that of your passengers also depends on
making sure that load limits are
not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR") .
The "GVWR " includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant
and other fluids plus maximum load. The maximum load in­
cludes the number of passen­
