Selective catalytic reduction
General information
Applies to vehicles: with selective catalytic reduct ion
In vehicles with selective catalytic reduction, a
urea solution (Ad Blue) is injected into the ex­
haust system before
a nitrogen oxide catalytic
converter to reduce nitrogen emissions .
The AdBlue is carried in a separate tank in the ve­
hicle. The AdB lue usage accounts for approxi­
mately 0.5% to 1.2% of the diesel fuel that is
used.
When a message about refilling the Ad Blue ap­
pears in the instrument cluster disp lay, you must
refill the Ad Blue yourself or have it refilled by an
authorized Audi dealer or authorized Audi Service
Facility ¢
page 219.
(1) Tips
-The display indicates the distance remaining
that can be driven¢
page 218. If the Ad Bl­
ue tank is completely empty, the engine will
not start again after the ignition is switched
off.
-Ad Blue is required by law to operate this ve­
hicle .

Checking and Filling
"'Park your vehicle on a level surface.
"'Turn off the ignition.
"'Read the engine coolant level from the coolant
expansion tank
c:> fig . 200, <=> page 223,
fig. 197. With a cold engine, the coolant level
should be between the "MIN" and "MAX" mark­
ings . When the engine 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 illustration
<=> page 223 .
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
c::> page 29 will
blink until you add coolant and the level has been
restored to normal. Even though there is an elec­
tric coolant 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 coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant .
In a
sealed system, losses can occur only if the
boiling point of the coolant is exceeded as a re­
sult of overheating.
0 Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding radia­
tor repair fluid may adversely affect the func­
tion and performance of your cooling system
and could result in damage not covered by
your New Vehicle Limited Warranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS

Replacement engine coolant must conform to ex­
act specifications
c::> page 22 7, Coolant.
We recommend using only coolant additive Gl2+
+, Gl3
or in an emergency Gl2+. Do not use a
different additive. In an emergency use plain wa­
ter until you can get the correct additive and can
restore the correct ratio. This should be done as
soon as possible.
If you have lost a considerable amount of cool­
ant, then you should add cold antifree ze and cold
water only when the engine is cold.
Always use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
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 while applying
light, downward pressure on the top of
the cap.

-To avoid being burned, do not spi ll anti­
freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­ ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original conta iner and well out
of the reach of ch ildren .
-If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do not continue driving. Seek profess ional
ass istance.
- Coolant pollutes the env ironment and could
cause an eng ine fire . Excess coolant will be
fo rced out through the pressure relief valve
i n the cap when the eng ine becomes hot.
- If, i n an emergency , only water can be add­
ed, the correct ratio between wa ter and an­
tifreeze
~ page 22 7 must be restored as
soon as possib le .
@) For the sake of the environment
Drained coolant should not be reused. Always
dispose o f used coolant while observ ing all
environmental regulations .
Radiator fan
The radiator fan switches on automatically by it­
self.
The radiator fan is driven by the engine via the V­
be lt . The viscous clu tch regulates the speed of
the fan ac cording to the temperature of the cool ­
ant.
An auxiliary e lectr ic rad iator fan* switches on and
off depend ing on coolant temperat ure and othe r
veh icle operating conditions.
Afte r you switch the engine off, the auxiliary fan
can continue runn ing for up to 10 minutes -even
Ch eck in g and Fillin g
with the ignition off . It can even switch on again
later by itself¢& , if
- the temperatu re of the engine coo lant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the
veh icle is parked in intense sun light .
A WARNING
-To reduce the risk of persona l injury never
touch the radiator fan .
- The auxiliary electric fan is temperature con­ trolled and can switch on suddenly even
when the engine is not running.
- The a uxiliary radiator fan sw itches on auto­
matica lly when the engine coolant reaches a
certain temperature and will continue to run
until the coolant temperature drops.

Disconnecting the battery terminals
Some vehicle functions (power window regula­
tors , for example) are lost if the battery termi­
nals are disconnected. These functions have to be
re learned after th e battery terminals are con­
nected again. To prevent this, the batte ry should
only be disconnected from the ve hicle electrical
system when absolutely necessary for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a period of
several days or weeks, e lectrica l components are
gradually cut back or switched off. This reduces
energy consumption and maintains starting ca­ pability over a longer period
c:> page 196.
Take into consideration that when you un lock
your veh icle, some convenience functions, such
as the interior lights or the power seat adjust­
ment, may not be available . The convenience
functions will be ava ilable again when you turn
on the ignition and start the engine.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. This is because
more power is also consumed while starting, and
the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, part icu­
larly in city traffic or when traveling only short
d istances . Let your authorized Aud i dealer check
the capacity of the vehicle battery before w inter
sets in
c:> page 232. A well charged battery will
not only prevent s tarting problems when the
weather is cold, but will also last longer.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­
ment under the floor. Before you check anything
in the lug gage compartment,
