Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect you r Audi Limited New
Vehicle Warranty.
<£> For the sake of the environment
• Before changing your oil, first make sure you know where you
can proper ly dispose of t he used oil.
• Always dispose of used engine oil properly . Do not dump it on
garden soil, wooded areas, into open strea ms or down sewage

Engine cooling system
Coolant
The e ngine coolant perfor ms tw o functions: i t kee ps the
en gine from overheatin g and i t pro tects the engi ne from
freezing in the winter.
The cooling system is sea led and general ly requires litt le attention.
The coo ling sys tem has been f illed at the factory with a permanen t
coo lant which does not need to be changed. The coolant consists of
a mixture of water and the ma nufacturer 's glyc ol- basedco olan t
additive
G12++ antifreeze w ith anti corrosion additives (50% for USA models; 60% for Canadian mode
ls) . T his mixture both assures the
n ecessary fros t pr otection a nd protects metal co mpo nents in the
engine's cooling system from corrosion and scaling. It also raises
t he boil ing point of the coolant .
Do not reduce the concentration of the coo lant in the su mmer by
adding plain water.
The proportion of coolant additive mu st be at
lea st 50 % but not more than 60 %
to maintai n antifreeze pro tection
and cooling efficiency. If the coolant frost protection is too low, the
coo la nt co uld free ze and damage the vehic le heating and engine
coo ling system .
For year-round driving, antifree ze is added at the factory for temper­
atures down to:
• - 31 °F ( -35 °C) USA
• -40 °F ( -40 °C) Canada.
You can mix the
G 12+ + coolant additive with other additives (G12+
or G12). Always check w ith your authorized Audi dealer.
& WARNING
Before you check anything in the engine compartment, alway s
read and heed all WARNINGS
~ & in "Working in the engine
compartment " on
page 217.
0 Note
• Before winter sets in, have the coolant checked to see if the
coo lant additive in your vehicle is suff icient to meet the c limate
co nd itions . This is e special ly impor tant i f you live in a region where
the winter is extremely cold. If necessary, increase the proportion of coo lant additive t o 60%.
• When adding coolant additive to your cooling system,
r emem ber:
- We recommend using on ly coolant additive
G 12+ + (check the
l abel) for your veh ic le . Th is coolant additive is available at autho -
rized Audi dealers. Other types of antifreeze can significantly ._

Checking and filling -
---------------------=----"=---------
reduce corrosion protection. The resu lting 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 of 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 checked with a quick
gla nce .
Fig . 142 Engine
co mp artm ent : coo lan t
e xpa nsion t ank
Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compa rtment" on
page 217.
- Switch the ignition of f.
- Read the coo lant l eve l at the coo lant exp ansio n tank
==> fig. 142. With a col d e ngine, it must b e above the
"min" mar k. Wit h a hot engine, it can be a little above t he
indicated range.
The location of the coolant expansion tank can be seen in the
engine compartment i llustration. To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehic
le is equipped with an e lectric
coolant level sensor.
When the coolant leve l is too low, the warning light in the Auto ­
Check System =>
page 34 will blink un til you add coolant and the
level has been restored to normal. Even though there is an e lectric
coo la n t level sensor, we still recommend you check the coolant level
from time to time .
Coolant loss
Coolant loss may indicate a leak in the cooling system . In the event
of coo lant loss, the co oling sys tem shou ld be i nspected immedi­
ate ly by your authorized Audi dealer . It is not enough merely to add
coo lant .
In a
sealed system , losses can occur only if the boiling point of the
coolant is exceeded as a result of overheating .
0 Note
Do not add any type of radiator leak sea lant to your vehicle's engine
coolant. Adding rad iator repair fluid may adversely affect the func ­
tion and performance of your coo ling system and could resu lt in
damage not covered by your New Vehic le Limited Warra nty. •
Adding coo lant
Be very careful when adding engine coolant.
Before you check anything in the engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 217 .
-Turn off the engin e.
- Let the engine cool down.

7. Connect the other end of the black jumper cable to the
negative terminal (bolt head)
G) in the external starting
point @of your vehicle.
8. Route the jumper cables so that they cannot catch in any
rotating parts in the engine compartment.
Starting the engine
9. Start the engine of the vehicle providing assistance and
allow it to run at idle.
10. Now start the engine of the vehicle with the discharged
battery , wait for two to three minutes until the engine
"runs" smoothly.
11. If the engine does not start: Stop trying after 10 seconds
and then try again after about 30 seconds.
12. In the vehicle that has received start assistance, turn on
the heater blower and the rear window heating to elimi­
nate any voltage peaks when disconnecting. Driving
lights must be switched off!
13. Disconnect the cable while the engine is running exactly
in
reverse order to that described in=> page 280,
"Connecting/disconnecting the jumper cable.". When
doing so, make sure that the cable cannot contact
rotating engine parts.
14. Close the cover on the posit ive terminal.
The battery is vented to the outside to prevent gases from entering
the vehicle interior. Make sure that the jumper clamps are well
connected with their
metal parts in full contact with the battery
terminals.
& WARNING
To avoid serious personal injury and damage to the vehicle, heed
all warnings and instructions of the jumper cable manufacturer.
If
in doubt, call for road service .
• Jumper cables must be long enough so that the vehicles do not
touch.
• When connecting jumper cables, make sure that they cannot
get caught in any moving parts in the engine compartment.
• Before you check anything in the engine compartment, always
read and heed all WARNINGS=>
page 209, "Engine compartment" .
0 Note
Improper hook-up of jumper cables can ruin the generator.
• Always connect POSITIVE(+) to POSITIVE (+l, and NEGATIVE(-) to
NEGATIVE( -) ground post of the battery manager control unit.
• Check that all screw plugs on the battery cells are screwed in
firmly. If not, tighten plugs prior to connecting clamp on negative
battery terminal.
• Please note that the procedure for connecting a jumper cable as
described above applies specifically to the case of your vehicle
being jump started. When you are giving a jump start to another
vehicle , do
not connect the negative(-) cable to the negative 1-1
terminal on the discharged battery ©-Instead, securely connect
the negative (-1 cable to either a solid metal component that is
firmly bolted to the engine block or to the engine block itself . If the
battery that is being charged does not vent to the outside, escaping
battery gas could ignite and explode! •
