Using the proper engine oil is important for the
functionality 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.
{tD 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 wi th the Audi oil quality
standard specified for your vehicle's engine.
Using any other oil can cause serious engine
damage.
- Do not mix any lub ricants or other additives
i nto the engine oil. Doing so can cause en­
g ine damage.
@ Tips
If you need to add oil and there is none availa­
ble tha t meets the Audi o il quality standard
your eng ine requi res, you may add a tota l of
no more than 0 .5 quart/li ter of a h igh-quality
"synthetic"oil that meets the fo llowing speci­
fications.
- Vehicles with gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W-30 or SAE 5W-40.
- Vehicles w it h diese l engine: ACEA C3 o r
API CF with a viscosity grade of SAE OW-30
or SAE 5W-30.

Engine 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 effective lub rication and cool ­
ing of internal engine components, all internal
combust ion engines consume a certa in amount
of oil. Oil consumption var ies from engine to en­
gine and may change significantly over the life of
the engine . Typically, engines w ith a specified
break-in period (see
c::;,page 194) consume more
o il dur ing the break-in per iod than they consume
after o il consumption has stabi lized .
Under normal cond itions, the rate of oil con­
sumption depends on t he quality and viscos ity of
the oil, the RPM (revolutions per m inute) at
wh ich the engine is operated, the ambient tem­
perature and road condit ions. Furthe r facto rs a re
t h e amount of o il d ilution from water condensa­
tion or fue l residue and the oxidation level of the
oi l. 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 a ll these variab les coming into p lay, no
standard rate of oi l consumption can be estab­
li shed or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the yellow engine oil level warning symbo l in
the instrument cluster
Ill lights up, you should
check the o il level as soon as possible

Driving with an insufficient oil leve l is likely to
cause severe damage to the engine .
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. 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 yo u have the impression your engine con ­
sumes excessive amounts of oil, we recom ­
men d that you cons ult an autho riz ed Au di
dealer to hav e the ca use of your conce rn
properly diagnosed. Keep in mind that the
a ccu ra te measurement of oil consump tion
r equi re s gre at care and m ay ta ke some
time. An a uthorized Audi de aler has instr uc­
tions about how to measure oil consump­
tion acc urately.

Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant level is monitored through the. in­
dicator light
¢page 26. However , we do recom­
mend occasionally check ing the coo lant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freez ing and
corros ion protection agents. Only use the follow­
ing coolant addit ives . These additives may be
mixed with each other.
Coolant additive Specification
G13
TL 774 J
G12++ TL 774 G
The amount of coo lant add itive that needs to be
mixed with water depends on the climate where
the vehicle will be operated.
If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the engine.

er when charging your battery.
- Never charge a frozen battery . It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen .
The battery housing may have cracked and
weakened when the battery froze .
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark . Do not smoke. Hydrogen gas generat ­
ed by the battery is explosive .
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charging a battery is dangerous and should only be attempted by a competent
technician with the proper equipment .
- Battery acid that may spill during charging should be washed off with a solution of
warm water and baking soda to neutralize
the acid.
(D Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi­
tive electronic components, such as control
units , relays , radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
~ page 192. The intelli­
gent energy management system will keep the
engine battery charged better then vehicles with­
out this system. To mak e sure the additional
electrical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture only (the same as those installed at the
time your vehicle was delivered) . Specifications
228
are listed on the battery housing. Your author­
ized dealer must cod e the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
placing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are turned off.
([) Note
- Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of bat­
tery can cause problems in the vehicle elec­
trical system. When replacing the vehicle battery, always install one with the same
specifications as the original battery.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is
very danger­
ous to the environment.
