Using the prope r engine oil is important for the
functiona lity and service life of the eng ine. Your
engine was factory-filled with a high -quality oil
which can usually be used throughout the entire
year.
@ Note
Your Limited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended maintenance and use
requirements as set forth in the Audi Owner's Manual and Warranty
& Maintenance booklet.
- Use only a high quality eng ine oil that ex-
pressly complies with the Aud i oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage .
- Do not mix any lubricants or other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
your eng ine requ ires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the followi ng speci­
fications.
- Vehicles with gasoline eng ine: AC EA A3 o r
API SM wi th a viscosity g rade of SA E OW-30,
SAE SW-30 or SAE SW-40.
- Vehicles wit h diesel eng ine: ACEA C3 o r
API CF with a v iscosi ty grade of SA E OW-30
or SA E SW -30.

Ch eck ing and Filling
Engine oil consumption
The engine in your vehicle depends on on ade­
quate amount of oil to lubricate and cool oil of
its moving ports.
In order to provide effect ive lubrication and cool­
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption varies from eng ine to en­
gine and may change s ign ificantly ove r the life of
the engine. Typ ica lly, engines w ith a specified
break-in period (see
¢ page 197) consume more
oi l during the break -in period than they consume
after oil consumption has stabilized.
Under normal cond itions, the rate of oil con­
sumption depends on the q uality and viscosity o f
the oil, the RPM (revol utions per minute) at
which the engine is operated, the ambient tem­
perature and road condit ions. Further factors are
the amount of oil dilution from water condensa­
tion or fuel residue and the oxidation level of the o il. As any engine is subject to wear as mileage
builds up, the oil consumption may increase over
time unt il replacement of worn components may
become necessary.
With all these variables coming into play, no standard rate of o il consumption can be estab­
li shed or spec ified . T he re is no alte rnative to reg­
u la r and frequent checking of the oi l level , see
Note .
If the yellow engine o il leve l warning symbo l in
the instrument cluster
II lights up, yo u should
c h eck the o il level as soon as possible

venience

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
i t. Instead , check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
dealer to have the cause of your concern
properly diagnosed . Keep in mind that the
accurate measurement of oil consumption
requires great care and may take some
time. An authorized Audi dealer has instruc­
tions about how to measure oil consump­
tion accurately.
Checking the engine oil level
Fig. 198 D is play: Oil level indicator
Read oil level
• Park yo ur vehicle so that it is hor izonta lly level.
• Shut the engine off when it is at operating tem-
perature.
• Switch only the ignition back on.
• Wait approx . two minutes.
• Se lect:
ICARI function button > Oil level. Or
• Se lect:
ICARI funct ion button> Car systems *
control button > Servicing & checks > Oil level.
• Read the oil level in the radio or MMI* Display
¢
fig. 198. Add engine o il if the bar of the oil
level indicator is near "Min"
Q page 224.
The oil level needs to be checked at regular inter­
vals. The best times to do this are whenever you refuel and pr ior to long trips .
224
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 liter per
1,000 km). Consumption may be higher w it hin
the first 3,000 miles (5,000 km).
(D Tips
The o il level indicator in the radio or MMI*
D isp lay is only an information display. If the
oil level is too low, a m inimum oil warning ap­
pears in the instrument cluster. Add oil

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 220 .
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
l ubricat ing propert ies of o il d iminish gradually
du ring normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authori zed
Audi dealer or
a qual ified service stat ion.
If y ou choo se to chan ge your oil your self , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amou nt of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of childre n.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
«I) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi limited New Vehi­
cle Warranty .

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
qu ires little attention .
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed. The coolant consists of
a mixture of
specially conditioned water and the manufactur­
er's g lycol-basedcoo lant additive G 13 antifreeze
w ith anticorrosion addi tives (50% for USA mod­
e ls· 60% for Canadian mode ls). This m ix ture
'
both ass ures the ne cess ary fros t protection and
p rotects metal com ponents in the engi ne's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ra tion of the cool ant in
the s ummer by addi ng p la in water.
The propor­
tion of coolant additive must be at lea st 50 %
but not more than 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coo lant could
freeze and damage the vehicle heat ing and en­
g ine cooling system .
For year -round driving, antifreeze is added at the
factory for temperatures down to:
- -3 1 °F
c -3s0c) usA
- -4 0° F ( -40°C) Canad a.
I f you must add coolant, use a m ixt ure of wa ter
and coolant add it ive. M ixing the coolant additive
with d istilled water is recommen ded.
_& WARNING
B efore you che ck anyt hing i n the engine com ­
partmen t, a lways read and heed all WARN -
226
INGS ~ & in Working in the engine compart­
ment on page 220.
(D Note
- Be fore w inter sets in, have the coolan t
checked to see if the coo lant additive in your
vehicle is suff ic ient to meet the climate con­
ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold. If necessary, increase the proportion
of coolant addi tive to 60% .
- Whe n adding coolant additive to your cool­
ing system, remember:
- We re commend usin g on ly coo lant addi­
tive G12++ o r G13 fo r yo ur vehicle. This
coolant ad dit ive is availab le at authorized
Audi dealers. Other types of antifreeze can
significantly reduce corrosion protection.
The resulting corrosion can cause a loss of
coolant and serio us engine damage.
- Do not add any type of radiato r leak sealant
to your vehicle's engine coolant. Adding ra­
diator repair fluid may adversely affect the
function and perfo rmance of yo ur cooling
system and cou ld resu lt in damage not cov­
ered by your New Ve hicle Li mited War ranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

should be between the "MIN" and "MAX" mark­
i ngs . When the engine is warm, the level may
be s light ly above the
"MAX " marking .
T he location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion

To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 29 wi ll
blink until you add coolant and the level has been
restored to normal. Even though there is an e lec­
tr ic 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
syst em. In the event of coolant loss, the cooling
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 coo lant is exceeded as a re­
sult of overheat ing .
(D Note
Do not add any type of radiator leak sealant
to your veh icle's engine coolant. Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .

Changing brake fluid
Have the brake fluid changed by an experienced technician.
Brake fluid absorbs mo isture from the air. If the
water conte nt in the brake fluid is too h igh, cor­
ros ion in the brake system may resu lt after ape­
riod of time. The boiling poi nt of the brake flu id
will also dec rease cons iderably and decrease

Checking and Filling
Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors, for example) are lost if the battery termi ­
na ls are disconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent this, the battery should
only be disconnected from the vehicle e lectrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. This reduces
energy consumption and ma intains starting ca­
pab ility over a longer period
c::> page 195 .
Take into consideration that when you unlock
your veh icle, some convenience functions, such
as the interior lights or the power seat adjust­
ment, may not be available. The convenience
functions will be available again when you turn
on the ignition and start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. This is be­
cause more power is also consumed while start­
ing, and the head lights, rear window defogger,
etc., are used more often.
Avoid unnecessary power consumption, particu­
larly in city traffic or when traveling only short
d istances . Let your authorized Audi dealer check
the capacity of the vehicle battery befo re winter
sets inc::>
