234 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission 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 of automatic trans­
mission 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.

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
power plant that was bu ilt to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right oil
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine will
get the lubrication it needs for proper opera-
tion. .,..

Detergent additives in the oil will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the o il more often than
recommended.
D amage o r m alfu nctions due to lac k of
m ainten ance
It is essen tial that yo u change your oil at the
recommended inte rva ls using only engine oil
that complies with A udi oil standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­ nance and use requ ireme nts as set forth in
the Audi Owner 's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage u nless you p resent to
the dea ler proof in the form of Serv ice or Re­
pa ir Orde rs that all scheduled maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective l ubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amo unt of oi l. Oi l cons umption varies from
engine to engine and may change significantly
over the life of the eng ine . Typ ically, eng ines
with a specified break-in per iod (see
c:> page 205) consume more o il during the
break-in per iod than they consume after oil
consumption has stab ilized .
Under normal conditions, the rate of oil con­
sumpt io n depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is ope rated, the ambient
temperature and road condi tions. Furt her fac­
tors are the amo unt of oil d ilution from wate r
condensation or fuel residue and the oxida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump ­
tion may increase over time until rep lacement
of worn components may become necessary.
Checkin g and fillin g 237
With a ll these variab les coming into p lay, no
standard rate of oil consumption can be es ­
tab lished or spec ified . There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instrument cluster
Ill li ghts up, you
sho uld check the oil leve l as soon as possib le
c:> page 238. Top off the oil at your earliest
convenience
c:> poge 238.
A WARNING
Before you check anything in the eng ine
compartment, always read and heed all
WAR NINGS
c:> & in Working in the engine
compor tment on page 233.
(D Note
D riving w it h an insufficient o il level is like­
l y to cause severe damage to the engine.
© Tips
- The oil pr essur e warn ing display. i s
not an indicator of th e oil level. Do not
rely on it. Instead, check the oil level in
your engine at regu lar int erval s, pr ef­
erably e ach time you refu el, and alway s
before going on a long trip .
-If you have the impression yo ur engi ne
c ons umes excess ive amoun ts of oil , we
recommend that you consu lt an author ­
ized Audi dea ler to have the cause of
your conce rn properly d iagnosed. Keep in
mind that the accurate measurement of
oil consumption requ ires great care and
may take some t ime . An authorized Aud i
deale r has instructions about how to
measu re oi l consumption accurate ly .

The oil level needs to be checked at regular in­
tervals . The best times to do this are whenev­
er you refuel and prior to long trips .
Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to a 1/2 quart per 600 miles (0.5
li­
ter per 1,000 km). Consumption may be high­
er within the first 3,000 miles (5,000 km).
@ Tips
The oil level indicator in the radio or MMI*
Display is only an information display. If
the oil level is too low, a minimum oil
warning appears in the instrument cluster.

Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways rea d and he ed all WARN ­
INGS
~ &. in Working in the engine compart­
ment on page 233.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during normal vehicle use.
Under some circumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traff ic con­
d itions, or have your veh icle where tempera­
tures remain below freezing for extended pe ­
riods.
Detergent additives in the o il w ill make fresh
oil look dark after the engine has been run­ n ing for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposa l,
along w ith the special tools and necessary ex ­
pertise required, we strongly recommend that
you have you r oi l changed by an authorized
Au di de ale r o r a qual ified servi ce station.
If y ou c hoose to c ha ng e y our o il yo urse lf,

A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in p lug with
your fingers, stay as far away as possible. Always keep your forearm parallel to the
ground to help p revent hot oil from run­
ning down you r arm.
- Dra in the oil into a container designed
for this purpose, one la rge enough to
hold at least the tota l amount of oi l in
your eng ine .
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact wit h used eng ine o il
is harmful to your s kin. A lways protect
your skin by washing oil off tho ro ughly
with soap and water.
@ Note
Neve r mix oil additives with your engine
oil. These additives can damage your en­
g ine and adversely affec t you r Aud i Lim it­
ed New Vehicle Warranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you c an properly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams or down
sewage drains .
- Recycle used engine oil by taking it to a
used engine oil collect ion facility in your
area, or contact a service station.

240 Checking and filling
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 .
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly­
col-based coolant additive Gl3 ant ifreeze
with anticorros ion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and engine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- - 31 °F ( - 35°() USA
- - 40°F ( - 40°() Canada .
A WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS
c:> &. in Working in the engine
compartment on page 233.
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in
your vehicle is sufficient to meet the cli­
mate cond itions. This is especially impor­
tant if you live in a region where the w in- ter
is extreme ly cold . If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or Gl3 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro ­
sion can ca use a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal ­
ant to your vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 199 Engine compartment : cover on t he coolant
expansion tank
Before you check anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS c:> &. in Working in the engine compart­
ment on page 233 .
.. Park your vehicle on a level surface .
.. Turn off the ignition .
.. Read the engine coolant level from the
coolant expansion tank
c:> fig. 199,
c:> page 235, fig. 196 . With a cold engine,
the coolant level should be between the
"MIN" and "MAX" markings. When the

engine is warm, the level may be slightly
above the "MAX" marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢
page 235.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 30 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the 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.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage
not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine compart­
ment on page 233.
... Turn off the engine .
... Let the engine cool down.

A.
... Add coolant.
... Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 240, Coolant. We
recommend using only coolant additive
Gl2+
+, Gl3
or in an emergency Gl2 +. Do not use a
different additive . In an emergency use plain
water until you can get the correct additive and can restore the correct ratio. This should
be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of
scalding 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 while
applying light, downward pressure on
the top of the cap .
- To avoid being burned, do not spill an­
tifreeze or coolant on the exhaust sys­
tem or hot engine parts. Under certain
conditions, the ethylene glycol in en­
gine coolant can catch fire.
-Antifreeze is poisonous. Always store an­
tifreeze in its original container and well
out of the reach of children.

24 2 Ch ecking and filling
-If you drain the coolant, it must be
caught and safely stored in a p roper
conta iner clearly marked "poison".
(D Note
- Coolant pollutes the env ironment and
could cause an engine fire . Excess coo l-
ant will be forced out through the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an emergency, only water can be
added , the correct ratio between water
and antifreeze¢
page 240 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself
The radiator fan is driven by the engine via the
V-be lt . The viscous clutch regulates the speed
of the fan accord ing to t he temperature of the
coolant.
An auxiliary electric radiator fan* switches on
a nd off depending on coolant temperature
and other ve hicle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself¢&. , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the veh icle is parked in intense sunlight.
_&. WARNING
- To reduce the r isk of personal injury nev­
er to uch the radiator fa n. -
The a uxiliary electric fan is temperat ure
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on a u­
tomatically when the engine coolant reaches a certai n temperature and will
continue to ru n until the coolant temper­
ature drops.
