cap
Fig. 185 Ad8lue filler tub e: inse rting the refi ll bott le
The Ad Blue fi ller tube is located near the die­
sel filler tube. Always add 1.5 gallons (5 . 7 lit­
ers) of AdBlue (three bottles). This is the mini­
mum amount required to ensure the system
detects the refilling and to start the engine.
The Ad Blue tank capacity is approximately
4 .5 gal lons (17 liters).
Opening the filler tube and adding
AdBlue
Requirement: The request to add Ad Blue must
appear in the instrument cluster display.
• Switch the ignition off.
• Open the tank cover
c:;,poge 216.
• Turn the cap counterclockwise with the lug
wrench from the vehicle too l kit to remove it

piratory system. If there is contact with
the fluid, flush immediately with plenty of
water. Consult a phys ician if necessary.
(D Note
-Only use Ad Blu e that conforms to the
standard ISO 22241-1. Do not mix any
additives with the AdBlue and do not di­
lute it with water.
- Do not add Ad Blue to the diese l tank or
add diese l fuel to the Ad Blue tank. Mix­
ing can lead to damage to the engine
and the AdBlue tank system . The Limited
New Vehicle Warranty does not cover

Before you check anything in the engine com­
partment,
al ways r ead and heed all W ARN­
ING S r=;, A in Working in the engine compart­
ment on page 222.
.. Park your vehicle on a level surface.
.. Switch
off the ignition .
.. Read the eng ine coolant leve l from the cool­
ant expansion tank¢
fig. 191, ¢ page 224,
fig. 188.
With a cold engine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
mark ing .
The location of the coolant expans ion tank
can be seen in the engine compartment illus­
tration ¢
page 224.
To obta in an accurate read ing, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
¢ page 16 will
illum inate until yo u add coolant and the level
has been restored to normal. Even though
there is an electric coo lant level sensor, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a lea k in the 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 coola nt.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing .
A WARNING
The coo ling system is unde r pressure and
c an get ve ry ho t. Reduce the risk of s cald­
ing from h ot coolan t by followi ng these
steps .
- T urn
off the engine and allow it to coo l
down.
Checkin g and fillin g 229
-Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying lig ht, downward pressure on the
top of the cap .
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, th e ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coolant. Add-
i ng radiator repa ir flui d may adverse ly af­
fe ct the funct ion a nd pe rfo rma nce of you r
co oling system and could re sult in damage
not covered by your New Vehicle Limi ted
War ranty.
Adding coolant
Be very careful when adding engine coolant.

230 Check ing and filling
We recommend using on ly coo lant addi-
tive
Gl2++, Gl3 or in an emergency Gl2 +. Do
not use a different additive . In an emergency
use plain water unt il 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 cons iderable amount of
coolant, then you should add co ld antifree ze
and cold water only when the engine is co ld.
A lways use
new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolan t will be forced out through the
p ressure relie f valve in the cap when the en ­
gine becomes hot.
A WARNING
- The coo ling system is under press ure and
can get very hot. Reduce the risk of
sca lding from hot coolant by following
these steps.
- Turn off the eng ine and a llow it to cool
down.
- Protect your face, han ds and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- Tur n the cap slowly and very c arefully
in a counter-clockwise d irect ion while
applying light, downward press ure on
the top of the cap .
- To avo id being burned, do not sp ill an ­
tifreeze or coolant on the exhaust sys ­
tem or hot engine parts. Under certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and well
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clear ly marked "poison".
- Do not add coolant if the expansion tank
is empty. A ir could enter the cooling sys­
tem and damage the eng ine. If this is the case, do not cont
inue driving . Seek
professiona l assistance .
- Coo lant poll utes the environmen t and
co uld cause an engine fire . Excess cool­
ant will be forced out thro ugh the pres­
sure relief valve in the cap when the en­
gine becomes hot.
- If, in an eme rgency, only wate r can be
added, the correct ratio between water
and antifreeze
c::> page 228 must be re­
stored as soon as possible .
@ For the sake of the environment
Drained coolant should not be reused . A l­
ways d ispose of used coolant while observ­
i ng all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself.
An a uxiliary electric radiator fan switches on
and off depending on coolant temperature
and other vehicle operat ing condit ions .
After yo u switch the engine off, the auxi liary
fan can continue r unning for up to 10 minutes
- even w ith the ignition off . It can even switc h
on again later by itself
c::> .& , if
- the temperature of the engine coo la nt rises
due to the heat build- up from the engine in
the engine compartment, or
- the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
A WARNING
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The a uxiliary electric fan is temperat ure
controlled and can sw itch on suddenly
even when the engine is not ru nning .
- The a uxiliary radiator fan sw itches on a u­
tomatically when the engine coo lant
reaches a certai n temperature and will
continue to run until the coolant temper­
ature drops.
