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
~ Adding engine oil
Fig. 163 Engine compartment: Cover on the oil filler neck
• 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.
