Using the proper engine oil is important for the
functionality and service life of the engine. Your
engine was factory-filled with a h igh-quality oil
which can usually be used throughout the entire
yea r.
(D 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 qual ity eng ine oil that ex-
pressly complies with the Audi 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.
@ Tips
If you need to add oil and there is none availa
ble that meets the Audi oil quality standard
your engine requires, you may add a total of
no more than 0.5 quart/liter of a h igh-quality
"synthet ic"oil that meets the following speci
fications.
- Vehicles w ith gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- For more information about engine o il that
has been approved for your vehicle, please

· Eng ine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lubricat ion and cool
i ng of internal engine components, all internal
combust ion eng ines consume a certa in amount
of oil. Oil consumption var ies from engine to en
gine and may change sign ificantly over the life of
the engine . T ypically, engines w ith a specified
break -in period (see¢
page 175) consume more
oi l during the break-in period than they consume
after oil consumption has stabilized.
U nder normal cond itions, the rate of oil con
sumption depends on the quality and viscosity o f
the oil , the RPM (revo lutions per minute) at
which the engine is operated, the ambient tem perature and road conditions. Further factors are
the amount of o il 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 o il consumption may increase over
ti me unt il replacement of wo rn compo nents 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 freq uent checki ng of the oi l level, see
Note.
If the yellow engine oil level warning symbo l II
in the instrument cluster lights up, you sho uld
chec k the o il level as soon as possible

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.
T he 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 condit ioned water and the manufactur
er's glycol-basedcoolant add itive G 13 antifreeze
with anticorrosion additives (SO% for USA mod
e ls; 60% for Canadian mode ls). This m ixture
both ass ures the necessa ry frost protection and
protects metal components in the engine's coo l
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
Do not red uce the concent ration of the coolant in
the summer by adding p lain water.
The propor
tion of coolant addit ive mu st be at least 50 %
but not more than 60 %
to mainta in antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en
g ine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to :
- -31° F(- 3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
If you must add coolant, use a m ixture of water
and coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .

INGS

(D Note
-Befo re winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the cl imate con -
Check ing and Filling
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 additive to 60%.
- When adding coolant additive to your cool
ing system, remember :
- We recommend us ing only coolant add i
tive G12+ + or G13 for yo ur vehicle. This
coolant addit ive is avai lab le at aut horized
A udi dealers . O ther types of antifree ze can
significantly reduce corrosion pro tect ion .
The resulting corrosion can cause a loss of
coolant and serious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra
diator repair fluid may adversely affect the
function and performance of your cooling system and cou ld resu lt in damage not cov
ered by your New Veh icle Limited Warra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.
