dealer to have the cause of your concern
properly diagnosed. Keep in mind that the
accurate meas urement of oil cons umption
requires great care and may take some time.
An authorized Audi dealer has instructions
about how to measure oil consumption ac­
curately.
Checking the engine oil level
Fig. 162 MMI Disp lay: Oil level indicator
Read oil level
• Park your vehicle so that it is horizonta lly level.
• Shut the engine off when it is at operating tem-
perature.
• Switch only the ignition back on.
• Wait approx. two minutes.
• Select: Function button
~IC ~A ~R~I > Oil level. Or
• Se lect: Funct ion button
ICARI > Car systems*
control button > Servicing & checks > Oil level.
• Read the oil level in the MMI* Display
r:::>fig. 162. Add engine o il if the bar of the oil
level indicator is near "min"
r:::>page 195
Depending on the way the vehicle is driven and
the operating conditions, oil consumpt ion can be
up to a 1/2 quart per 600 miles (O.S liter per
1,000 km) . Consumption may be higher within
the first 3,000 miles (S,000 km).
@ Tips
The oil level indicator in the MMI* Display is
only an information disp lay. If the oil level is
too low, a minimum oil warn ing appears in
the instrument cluster. Add oil¢
page 195.
If the hood has been opened, the current oil
level is shown in the instrument cluster the
next time the ignition is switched on.
Checking and Filling

• 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 191.
• Shut the eng ine off.
• Unscrew the cap~ to the eng ine oil filling
hole
¢ fig. 163, ¢page 193, fig. 161.
• Carefully top off with 0 . S quarts (0.5 liters) of
the appropriate oi l
¢page 193.
• Check the oil level again after two minutes
¢ page 195, Checking the engine oil level.
• Top off the o il aga in, if necessary.
• Screw the cap back on the filling hole.
A WARNING
-
- Wh ile topping off, the o il must not come in
contact w ith hot engine parts -fire hazard!
- The oil filler cap must be properly secured to
p revent oil from being sprayed on the hot
engine and exhaust system when the engine
is running -fire hazard!
- If you r skin has come in contac t with the en­
g in e oi l, you must subsequently cleanse it
thoroughly.
CJ) Note
- Check the oil level using the radio or MMI*.
If the message
Please reduce oil level ap­
pears, contact your authorized Audi dealer
or qualified workshop to have excess oil ex­
tracted if necessary.
-Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle War-
ranty. ..,.

Checking and F ill in g
@ For the sake of the environment
- Under no circumstances can the oil come in
contact with the sewage network or the soil.
- Observe and fo llow lega l regu lations 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 service sta­
tion.
Before you check anything in the engine compa rt ­
ment,
alway s read and heed all WARNINGS ¢ .&.
in Working in the engine comportment on
page 191.
The engine oil must be changed according to the
i n terva ls specified in yo ur Warranty
& Mainte­
nance booklet . This is very important because the
lubricat ing propert ies of o il diminish gradua lly
during normal vehicle use.
Under some circ umstances the engine oi l sho uld
be changed more frequent ly . Change oil more of­
ten if you drive most ly short distances, operate
the vehicle in dusty areas or under predom inantly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures rema in below freezi ng
for extended periods.
Detergent addit ives in the o il w ill make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
cha nge the oil mo re often than recommended .
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
qu ired, we stro ngly recommend that you have
your oil changed by an autho rized
Aud i deale r or
a qualif ied se rvice stat ion.
If you choose to change your o il yourself, please
note the fo llowing important information :
A WARNING
To reduce the ris k of persona l inju ry if yo u
must c han ge the engine oil in your ve hicle
yo urself:
- Wea r eye p rotection .
196
-
-To reduce t he risk of burns from hot engine
oil, let the engine coo l down to the touch.
- W hen removing the o il drain p lug with your
fingers, stay as far away as possib le. Always
keep your forearm parallel to the ground to
he lp prevent hot oi l from running down your
arm .
- Dra in the oil into a c ontainer designed for
this purpose, one la rge enough to hold at
least the tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it we ll out of
the reach of chi ld ren .
- Continuous contact w it h used eng ine oi l is
ha rmf ul to your skin. Always protect you r
skin by washi ng oil off tho roughly wi th soap
a nd wate r.
(D Note
Never mix oil additives with your engine oil.
These additives can damage your e ngine and
adverse ly affect your Audi Limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before changi ng your oil, first make su re
you know where you ca n prope rly dispose of
the used oil.
- Always dispose of used eng ine oil properly.
Do not d ump it on garden so il, wooded
areas, in to op en st reams o r down sewage
drai ns.
- Recycle used engi ne oil by taking it to a used
eng ine oi l collect ion fac ility in yo ur area, o r
c ontact a service station.
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 genera lly re­
q u ires little attention.
The cooli ng sys tem has been filled at the f actory
wi th a permanent coolan t which does not need to
be changed. The coolant consists of a mixtu re of
jll,,

M N
i? co ,...., \!) 1.1"1
N 1.1"1 ,....,
specially conditio ned water an d the manu fa ctu r­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This m ixture both
assures the necessary frost protection and pro­
tects meta l components in the engine's cooling
system from corrosion and scal ing . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water .
The p ropor­
tion of coolant addit ive must be at l east 50 %
but n ot mor e th an 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant cou ld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory fo r temperatures dow n to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coo lant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
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 191.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in your
vehicle is suffic ient to meet the cli mate con­
dit ions. This is especially important if you
li ve in a region where the win ter is extreme­
l y co ld. If ne cessary, i ncrease the proport ion
of coo lant add itive to 60%.
- When adding coolant a ddit ive to you r cool ­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. This
coolant additive is ava ilable at authorized
Audi dea lers. Other types of ant ifreeze can
significant ly reduce co rrosion protection.
Checking and Fillin g
The resulting corrosion can ca use a loss o f
coolant and serious engine damage.
- Do not add any type of rad iator le ak sealan t
to your vehicle's engine coolant. Adding ra­
diator repai r fluid may adverse ly affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Lim ited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

.. Park your vehicle on a level su rface.
.. Tu rn off the ignition .
.. Read the engine coolant level from the coolant
expansion tank
¢fig . 164, ¢page 193,
fig . 161 .
With a cold engine, the coolant leve l
should be between the "M IN" and "MAX" mark­
ings. When the eng ine is warm, the level may
be slightly above the "MAX" marking.
The location of the coo lant expansion tank can be
seen in the engine compartment illustration
¢page 193.
To obtain an a ccur ate reading, the engine m ust
be switched off.
T he expansion tank in yo ur veh icle is eq uipped
with an electric coo lant level senso r.
When the coolant leve l is too low, the wa rn ing

Checking and F ill in g
blink until you add coo lant and the level has been
restored to normal. Even though there is an e lec­
tr ic coo lant level sensor, we still recommend you
check the coo lant level from t ime to time.
Coolant los s
Coolant loss may indicate a leak in t he cooling
system. 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.
I n a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
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 coo l
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag .
-Turn the cap slowly and very carefully in a
counter-clockw ise d irection while applying
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 ce rtain conditions,
the ethy lene g lycol in engine coolant can
catch fire.
{il) Note
Do not add any type of rad iator leak sealant
to your veh icle's engine coolant . Adding radia­
to r repair f lu id may adverse ly affect the func­
tion and performance of your cooling system
and could resu lt in damage not covered by
your New Vehicle Limited Warranty.

tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original conta iner and well out
of the reach of ch ildren .
-If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do not continue driving. Seek profess ional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire . Excess coolant will be
fo rced out through the pressure relief valve

@) For the sake of the environment
Drained coolant should not be reused. Always
dispose o f used coolant while observ ing all
environmental regulations .
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt . The viscous clu tch regulates the speed of
the fan ac cording to the temperature of the cool ­
ant.
An auxiliary e lectr ic rad iator fan* switches on and
off depend ing on coolant temperat ure and othe r
veh icle operati ng conditions.
Afte r you switch the engine off, the auxiliary fan
can continue runn ing for up to 10 minutes -even
Ch eck in g and Fillin g
with the ignition off . It can even sw itch on again
later by itself¢& , if
- the temperatu re of the engine coo lant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
veh icle is parked in intense sun light .
A WARNING
-To reduce the risk of persona l injury never
touch the radiator fan .
- The auxiliary electric fan is temperature con­ trolled and can switch on suddenly even
when the engine is not running.
- The a uxiliary radiator fan sw itches on auto­
matica lly when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases , other parts of the car must first be re­
moved before you are ab le to get to the bulb .
This applies especially to the light bulbs in the
front of you r ca r which you can only reach
through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must be
Fuses and bulbs
correct ly taken apart and then properly put back
together to help prevent breakage of parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Audi dea ler replace any bulbs for
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the bulbs
replaced by a qualified technician . Head lights
with Xenon light are identified by the high volt­
age sticker.
A WARNING
Changing Xenon lamps without the necessary
equipment can cause serious personal injury.
- Bulbs are pressurized and can explode when
being changed . Potential risk of injury!
- On vehicles equipped with gas discharge
bu lbs (Xenon light) * life -threatening injuries
can result from improper handling of the
high -vo ltage portions of such lamps!
-On ly your authorized Audi dealer or quali­
fied workshop shou ld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
bulb holders that can cause serious cuts . If
you are uncertain about what to do, have
the wor k performed by an autho rized Audi
dealer or qualified workshop. Serious per­
sonal injury may result from improperly per­
formed work .
(D Tips
-If you st ill prefer to replace the light bulbs
yourself, be aware that the eng ine compart­
ment is a hazardous area to work
inq page191 q&_ ,
-It is best to ask your authorized Audi dealer
whenever you want to change a bulb.
