Dr iving with an insufficient oil level is like­
ly to ca use seve re damage to the eng ine.
{1) Tips
- The oil pressu re warning display. i s
not an indicator of the oi l level. Do not
rely on it. Instead , check th e oil level in
your engine at regular interval s, pref ­
erably each time you refuel, and always before going on a long trip .
-If yo u have the impres sion your engine
consumes excessive amo unts o f oil, we
r ecommend that yo u consult your Audi
dealer to have the ca use of yo ur conce rn
proper ly diagnosed . Keep in mind that
the accurate measurement of oil con­
sumption requires great care and may
take some time. You r Audi dealer has in­
str uctions about how to measure o il con­
sumption accurately.

when disposing of empty oil containers.
Changing the engine oil
We recommend that hove your oil changed by
on authorized Audi dealer or a qualified serv­
ice station .
Before you check anything in the engine com­
partment,
a lw ays r ead and heed all WARN­
ING S
c:> &. in Working in the engine comport­
ment on page 232.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet. This is very important
because the lubricating properties of oil di­
minish gradually dur ing normal veh icle use.
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly 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 fo r extended pe­
r iods.
Detergent additives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the oi l mo re often than
recommended.
Because of the problem of proper disposal,
along w ith the special tools and necessary ex­
pe rtise required, we strong ly recommend that
you have your oi l changed by an author ized
A udi dealer or a qualified service station.
Checkin g and fillin g 239
If yo u choose to change you r oil yo urs elf ,
please note the fo llowing important informa­
tion:
_& WARNING
To reduce the risk of personal injury if you
must change the engine 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 oi l dra in p lug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
grou nd to help prevent hot o il from run­
ning down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of oil in
your engine.
- Engine oil is poisonous. Keep it well o ut
of the reach of children.
- Continuous contact with used eng ine o il
is harmful to yo ur skin . A lways protect
your skin by washing oil off tho roughly
w it h soap and w ater.
d) Note
N eve r mix oil additives with your engine
oil. These additives can damage your en­
g ine and adversely affect your Audi Lim it­
ed New Vehicle Warranty.
@ For the sake of the environment
- Before changi ng your oil, first make sure
you know where you ca n prope rly dispose
of the used oil.
- Always dispose of used eng ine oi l proper­
ly. Do not dump it on garde n soil, wood­
ed areas, into open streams or down
sewage drains .
- Recycle u sed engi ne oil by taking it to a
used eng ine oil colle ct 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 (50% 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 antifree ze 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, antifree ze is added at
the factory for temperatures down to:
- -31°F(-35°C)USA
- - 40 °F ( - 40 °C) 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 232.
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. 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. 200 Engin e compar tmen t: cover on t he coolant
expansio n ta nk
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS c:> &. in Working in the engine compart ­
ment on page 232 .
Park your vehicle on a level surface .
.,. Switch off the ignition.
.,. Read the engine coolant level from the
coo lant expansion tank
c:> fig. 200,
c:> page 234. 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 234.
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 16will
illuminate until you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor , we
still recommend 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.
& 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 while ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill anti­ freeze or coolant on the exhaust system or hot engine parts . Under certain condi­
tions, the ethylene glycol in engine cool ­
ant can catch fire .
Checking and filling 241
@ 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 ¢ & in Working in the engine compart ­
ment on page 232 .
.,. Turn off the engine .
.,. let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢
page 240, fig . 200 and carefully
twist the cap counter-clockwise ¢&_ .
.,. 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 G12+
+, G3 or in an emergency G12+. 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
