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.
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.

Checking the engine coolant level
T he engine coolant level can be checked with
a quick glance.

always read and heed all WARN
INGS ¢ A in Working in the engine comport

.,. Park your vehicle on a level surface.
.,. Turn
off the ignition .
.,. Let the engine cool down.
.,. Place a thick rag over the coolant expans ion
tank ¢
fig. 245, c> page 259, fig. 241 and
carefully twist the cap counter-clockwise
¢,&. .
.,. Read the engine coolant level in the open
coolant expansion tank. With a cold engine,
the coolant level should be between the
"min " and "max" markings. When the en
gine is warm, the level may be slightly
above
the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus
tration
¢ page 259 .
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor .
When the coolant level is too low, the warning
light in the Auto-Check System¢
page 32 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec ommend you check the coolant level from
time to time .

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

- To avoid being burned, do not spill ant i
freeze or coolant on the exhaust system
or hot eng ine parts. Under certain condi

Do not add any type of radiator leak seal

When should I check the tire pressur e?
The correct tire pressure is especially impor

If a wheel bolt is very tight, you may find it
easie r to loosen by carefully pushing down
on the end of the wheel bolt wrench with
one foot only. As you do so, hold on to the
car to keep yo ur balance and take care not
to slip.

& WARNING
-You or your passengers could be injured
while changing a wheel if you do not
follow these safety precautions:
- Position the jack only at the designated
lifting points and align the jack. Other
wise, the jack could slip and cause an injury if it does not have sufficient hold
on the vehicle.
- A soft or unstable surface under the
jack may cause the vehicle to slip off the jack. Always provide a firm base for
the jack on the ground . If necessary,
use a sturdy board under the jack.
- On hard, slippery surface (such as tiles)
use a rubber mat or similar to prevent
the jack from slipping.
- To help prevent injury to yourself and
your passengers:
- Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the vehicle and
well away from the road and traffic.
- Make sure jack position is correct, ad
just as necessary and then continue to
raise the jack.
(D Note
Do not lift the vehicle by the sill. Position
the jack only at the designated lifting
points on the sill. Otherwise , your vehicle
will be damaged.

.,. Remove the alignment pin and insert and
tighten the remaining wheel bolt slightly
like the rest .
.,. Turn the jack handle counter-clockwise to
lower the vehicle until the jack is fully re
