Selective catalytic
reduction
General information
App lies to vehicles : with diesel engine
On vehicles w ith select ive catalytic reduction,
an urea solut ion (Ad Blue ®) is injected into the
exhaust system befo re a nitrogen oxide cata­
lytic converter to reduce nitrogen em iss ions.
The AdBlue is stored in a separate tank in the
veh icle. The AdBlue usage accounts for ap­
p rox imately 0.5% to 1.2% of the diese l fuel
that is used. The Ad Blue tank capaci ty is ap ­
pr ox ima tely 6 gallons (23 liters).
You must refill the Ad Blue or have it refilled
by your authorized A udi dealer or qualified
wo rkshop as soon as the Ad Bl ue refill mes-

(D Note
- Befo re win ter se ts in, have the coolan t
che cked to see if t he coolant ad dit ive in
you r vehicle is s ufficien t to mee t the cli ­
mate conditions. T his is especially impor­
tant if yo u live in a region where the w in­
ter is extremely co ld. If necessary, in­
crease the proport io n of coolant additive
to 60%.
- When adding coolant addit ive to your
cooling system, remember:
- We recommend using only coolant ad­
ditive G1 2++ o r G13 fo r your vehicle.
Thi s coo lant add itive is available at au­
thorized A ud i dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The res ulting corro ­
sion can cause a loss of coo lant and se­
r ious eng ine damage.
- Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coo lant.

The expansion tank in your veh icle is equipped
with an electr ic coo lant level senso r.
When the coolant leve l is too low, the warning
light in the Auto-Check System¢
page 32 will
blink unti l you add coolant and the level has
been resto red to normal. Even though there is
an electric coo lant level senso r, we still rec­
ommend you check the coolant level from
time to t ime .

Coolant loss
Coolant loss may indicate a leak 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 coolant.
In a
sealed 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 while ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill 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.
(D Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function 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 com­
partment,
always read and heed all WARN­

Replacement engine coolant must conform to
exact specificat ions
c:;, page 2 71, Coolant. We
recommend using only coolant additive G12+
+, G13 or in an emergency G12 +. Do
not use a
different additive. In an emergency use plain
water 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
coolant, then you should add cold antifreeze
and cold water only when the engine is cold.
Always use
new engine coolant when refilling .
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the
pressure relief valve in the cap when the en ­
gine 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

Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moist ure from the a ir. If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
brake fluid w ill also decrease considerably and
decrease b raking performance .
Therefore, the brake flu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standa rd "FMVSS 116 DOT 4".
The brake f lu id reservoir can be difficult to
reach, therefore, we recommend that yo u
have the brake f lu id changed by your author­
i zed
Audi dea ler . Your deale r has the co rrect
too ls, the right b rake fluid and the know-how
to do this fo r you.
_& WARNING
- Br ake fluid is po isonous . It must be s to r­
ed only in the closed orig inal con tainer
o ut of the reac h of c hildren!
- Br ake f ailure can resu lt from old or in ap ­
propr iate b ra ke fluid. Observe these pre ­
caut ions:
- Use on ly brake fluid that meets SAE
specif ication
J 1 703 and conforms to
Federal Motor V ehicle Sta ndard 116.
A lways check wi th you r auth o riz ed Audi
deale r to ma ke s ure you are using the
correct brake flu id . T he correc t type of
Checkin g and fillin g 275
brake f luid is also ind icated on t he
brake f luid rese rvoir.
- The bra ke fl uid must be new. Heavy use
of the brakes can cause a vapo r lock if
the brake fluid is left in the system too
l ong. This can seriously affect the effi­
c iency of the brakes as well as your
safe ty. This co uld resu lt in an accide nt.
(1) Note
Brake fluid will damage the paint of your
vehicle.
@) For the sake of the environment
Because o f the prob lem of proper disposal
of brake fluid as well as the spec ial too ls
required and the necessary expertise, we
recomme nd that you have the brake flu id
changed by you r autho rized Aud i deale r.
Battery
General information
U nder normal operating cond itions, the bat­
tery in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte level chec ked by an au thorized
Audi dealer or qualified wo rkshop . The elec­
t ro lyte level should also be che cked each time
t h e battery is cha rged
~ page 2 77.
Have the battery checked when you take your
vehicle in for se rv ice . You a re well advised to
replace a battery that is o lde r th an 5 years .
With certain types of airbag deployment, the ba tte ry is disconnected from the ve hicle elec­
t rical sys tem for safety reasons
~ A in Re­
pair, care and disposal of the airbags on
page 198.
Disconnecting the battery terminals
Some vehicle fu nctions (power window regu ­
lators, fo r example) are lost if the battery te r­
mina ls are disconn ected . T hese functions have
to be relearned after the bat tery termina ls are
conne cte d ag ain. To p revent t his, the battery .,.

should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs.
Vehicles not driven for long periods
If you do not drive your vehicle over a pe riod
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capab ility over a longer period
<=> page 231.
Take into consideration that when you un lock
your vehicle, some convenience functions, such as the interior lights or the power seat
adjustment, may not be available. The con­
venience functions will be available 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 de ­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short d istances . Let your authorized Audi
dealer check the capacity of the vehicle bat­
tery before w inte r sets in
<=> page 277. A well
cha rged battery w ill not only prevent starting
p rob lems when the weather is cold, but will
a lso last longer.
(D Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it will not freeze . This wi ll
prevent it from being damaged and having
to be replaced.
Working on the battery
