from forming.

256 Fuel supply and filling your fuel tank
• Press lightly against the bottom of the bot­
tle @to empty it. Continue pressing the
bottom of the bottle until it is empty or un­
til fluid stops flowing into the tank.
• Turn the bottle to the left without pressing
on the bottom .
Closing the filler tube
• Turn the cap clockwise on the filler tube
with the lug wrench until you hear it tighten
completely.
• Close the tank cover.
After filling
The vehicle must be driven. The system may
take up to two minutes to detect that the
Ad Blue has been filled.
• If there was no Ad Blue left in the tank and a
range of
O mi (0 km) was displayed in the
instrument cluster , switch the ignition on
for about 15 seconds before starting the en­
gine.
A WARNING
, -
AdBlue can irritate the skin, eyes and res-
piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a physician if necessary.
Q) Note
- Only use Ad Blue that conforms to the
standard ISO 22241-1. Do not mix any
additives with the Ad Blue and do not di­ lute it with water.
-AdBlue is not a diesel additive . Do not
add it to the diesel tank. If Ad Blue is
mixed with diesel fuel, it can lead to
damage to the engine and the Ad Blue
tank system. The Limited New Vehicle
Warranty does not cover such damage.
- Ad Blue attacks surfaces such as painted
vehicle components, plastic and carpet. Remove the fluid as quickly as possible
with a damp cloth and plenty of cold wa­
ter. If the Ad Blue has already crystal­ lized, use warm water and a sponge.
AdBlue residue that is not removed will crystallize and can damage the affected
surface.
- Do not store the refill bottle in the vehi­
cle. If it leaks, the escaping Ad Blue could
damage the vehicle interior.
- Do not allow Ad Blue to come into con­
tact with clothing. If there is contact
with the fluid, flush immediately with
plenty of water.
(D Tips
- You can obtain refill bottles from any au­
thorized Audi dealer or other qualified
workshop .
- Follow the Ad Blue manufacturer's in­
structions for usage and storage.

Engine oil
Engine oil specifications
The engine in your Audi needs the right kind
of oil.
The engine in your Audi is a sophisticated
powerplant that was built to exacting spec ifi­
cations . Th is eng ine needs the right k ind of
engine oil that meets specifications regardi ng
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the right o il
and changing oil within the time and mileage
intervals printed in your vehicle's Warranty
&
Maintenance booklet matters a lot more to­
day than it did years ago . Audi has deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle's engine w ill
get the lubrication it needs for proper opera­
tion.
Modern engine lubrication has taken a quan ­
tum leap in the last few years. Many synthetic

C han gin g the en gin e o il
The engine oil and oil filter must be changed
according to the m ileage (ki lomete rs) and
time inte rva ls specified in your vehicle 's War­
r anty
& M aintenance booklet. Do not ex ceed
t hese intervals -harmf ul depos its from old
engine oi l can reduce engine performance and
can lead to expensive engine repairs.
Changing the o il at the recommended inte r­
va ls is so very important because the lub ric at­
ing p roperties o f oi l decrease grad ually during
norma l vehicle use . If you are not sure when
you have yo ur oi l changed, ask your a uthor­
ized A udi Service Advisor.
Unde r some ci rc u mstances the engine o il
should even be changed more frequently.
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and-go traffic con­
d itions, or when you use your vehicle where
temperatures stay below freezing po int for
l ong periods .
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
ni ng fo r a short time . This is no rmal and is not
a reason to change the o il mo re often than
r ec om mended.
Damage or malfun ctions due to lack of
maintenance
It is essential that yo u change your oil at the
recommended interva ls using only engine oil
that complies with Audi oi l standard

· Engine oil consumption
To provide effective l ubr ication and cooling for
interna l eng ine parts, all interna l combustion
engines use some oi l. Oi l consumption varies
from eng ine to engine and may change over
the life of the engine . Engines tend to use
more o il du ring the b reak-in period tha n they
do afterward, when o il cons umption has sta­
bilized. Depend ing on the way the vehicle is
driven and the operating conditions, oil con­
s u mption can be up to
1 quart per 1,200
miles (l liter per 2,000 km) . Consumption
may be higher within the first
3,000 m iles
(5,000 km) .
U nder normal conditions , the rate of oi l con ­
s u mption depends on oi l quality as well as vis­
cosity, engine speed (rpm), outs ide tempera ­
ture, road conditions, the amount of oil dilu­
tion caused by condensed water or fue l resi­
due, and ox idat ion of the o il. Oi l consumption
may increas e with eng ine wear over time, un­
t il rep lacement of worn engine pa rts may be­
come ne cessa ry.
Because of all these var iables, there is no
standard o r "n orma l" rate of o il cons umption .
We urge you to check the engine oil level at
regular interval s, preferably every time y ou
fill the fuel t ank, and always before a long
trip .
The oil pres sure warning light. i s not an
indicator of low engine oil level. If the warn ­
ing light does not go out after starting, or
flashes while dr iving (above 1500 rpm), a
buzzer will sound. It indicate s that the oil
pressure is too low . Stop the engine immedi ­
ately , check the engine oil level and add oil if
necessa ry. If the engine oil level is normal,
but the l ight continues to fla sh, do not keep
driving or let the engine idle, as damage may
occur .

For year-round driv ing, antifreeze is added at
the factory for temperatures down to:
- - 31 °F (- 35 °C) USA
- - 40 °F ( - 40 °C) Canada .
If you mus t add coolant, use a mixture of wa­
ter and coolant additive. Mixing the coolant
additive with distilled water is recommended .
A WARNING
-
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 257.
(D Note
-Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extremely cold.
If necessary, in­
crease the proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive Gl2++ or G13 for your vehicle.
This coolant additive is available at au­
thorized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection . The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.

Coolant lo ss
Coolant loss may indicate a l ea k in t he cooling
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
se ale d system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Turn off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter -clockwise direction wh ile ap ­
plying light, downward pressure on the
