& WARNING (continued)
• When removing the oil drain plug with your fingers, stay as far
away as possible. Always keep your forearm parallel to the ground
to help 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 total amount of oil
in your engine.
• Engine oil is poisonous. Keep it well out of the reach of children.
• Continuous contact with used engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.
0 Note
Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty.
<£> For the sake of the environment
• Before changing your oil, first make sure you know where you
can properly dispose of the used oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil, wooded areas, into open streams or down sewage
drains.
• Recycle used engine oil by taking it to a used engine oil collec
tion facility in your area, or contact a service station. •
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from overheating and it protects the engine from
freezing in the winter.
The cooling system is sealed and generally requires 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 water and the manufacturer's glycol -basedcoolant
additive G12++ antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling. 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 proportion of coolant additive must be at
least 50% but not more than 60%
to maintain antifree ze protection
and cooling efficiency. If the coolant frost protection is too low, the
coolant could freeze and damage the vehicle heating and engine
cooling system.
For year-round driving, antifreeze is added at the factory for temper
atures down to:
• -31 °F
! -35 °ci usA
• - 40°F ( - 40°CJ Canada.
You can mix the G12++ coolant additive with other additives (G12 +
or G12) . Always check with your authorized Audi dealer .
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS

0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions. This is especia lly important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coo lant additive to 60%.
• When adding coolant additive to your coo ling system,
reme mber:
- We recommend using only coolant additive G12+ + (check the
label) for your vehicle. This coolant addit ive is ava ilable at autho
rized Audi dealers . Other types of antifreeze can significantly
reduce corrosion protection . 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 radiator repair fluid may adverse ly affect the
function and performance o f your cooling system and cou ld result
in damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coolant level
The engine coolant level can be checke d with a quick
glance.

coo lant.
In a
