2016 AUDI RS7 SPORTBACK cooling

CD Note
-Vehicle components such as the engine,
transm ission, suspension or electrical sys­
tem can be severely damaged by driving
through water.
- Determine the depth before driv ing through
water.
- Do not stop the vehicle, drive in reverse or
switch the eng ine off when dr iving through
water.
- Keep in mind that oncoming veh icles may
create waves that raise the water level and
make it too deep for your vehicle to drive
through safely .
- Avo id d riving through salt water (corrosion).
Warming up and cooling
down
By carefully warm ing up and cool ing down your
veh icle, you can he lp ensure that it is not over­
stressed un necessa rily during sporty driving.
When warming up, the vehicle is dr iven at a max­
i mum eng ine speed of 6000 RPM in order to raise
the eng ine oi l temperature to a min imum of
140 °F (60 °C). The tires a lso on ly reac h their f ull
road ho ld ing capability once they have warmed
up .
The cooling fan can continue to run in your vehi­ cle after the engine is swi tched off. Howeve r,
d riving the vehicle to cool it dow n is particularly
important. D uring sporty dr iv ing, the engine and
brakes, the exhaust system, and the transmission
a ll become extremely hot. Before you park the
ve hicle, you shou ld drive it for a few m iles/kilo­
meters at light load in the low rpm range to al­
low it to cool down.
Driving and the envir onment
Catalytic converter
Applies to: veh icles w ith gasoli ne e ngi ne
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
.. Always use lead-free gasoline¢ page 198,
Fuel supply.
.. Never run the tank down all the way to empty.
.. Never put too much motor o il in yo ur engine
¢ page 20 7, Adding engine oil 9:::r. .
.,. Never try to pus h- or tow-start your veh icle.
The catalytic co nverter is an efficient "clean-up"
device built into the exhaust sys tem of t he ve hi­
cle. The catalyt ic conv erter b urns ma ny of the
po llutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of un leaded fuel is cr itically im­
po rtant fo r the life of the catalytic converte r and
prope r fu nct io ni ng of the eng ine.
_&. WARNING
The tempe ra tu re o f th e exh aus t sys tem is
hi gh, bot h when driv ing and a fter stopping
the engine.
- Never tou ch the e xhaus t tail pipes on ce they
have become hot. This cou ld res ult in burns.
- Do not p ark or operate the vehicle in ar eas
where the hot exhaus t sys tem may come in
contact w ith dry grass, b rush, fuel spill or
other mate rial which can ca use a fire.
- Do not app ly additiona l undercoating or
r u stp roofing on or near the exhaust mani­
fold, exha ust pipes, cata lytic converter or
heat shields. D uring driving, the substance
used for undercoat ing could overheat and
cause a fire.
CD Note
- Be aware that just one tank fi lling with
leaded fuel w ill already seriously degrade
the performance of the catalytic converter.
- Do not exceed the correct engine oil leve l

Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
q ui res little atte ntion .
The cooling system has been filled at the factory
with a permanent coolant which does not need to
be changed . The coolant consists of a mixture of
specially condit ioned water and the ma nufactur ­
er's glycol-based coolant additive G13 an tifreeze
with ant icor rosion additives
(50% for USA mod­
e ls;
60% fo r Canadia n models). This m ix tu re
bo th ass ures the necessa ry fros t prote ction and
protects metal componen ts in the engi ne's coo l­
ing system from corrosion and scaling .
It also
raises the boiling point of the coolant.
D o not red uce the con cen trat ion of the coolant in
the summer by adding p lain wa ter.
The propor­
tion of coolant additive mu st be at least 50 %
but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
g ine cooling system .
For year-round driving, antifreeze is added at the
factory for temperatures down to:
- -3 1 °F ( -3 5 °C) USA
- -4 0 °F ( - 40 °C) Canada.
If yo u m ust add coo lant, use a m ixt ure of water
and coolant addit ive. Mixing the cool ant additive
with d istilled w ater is recommended .
_& WARNING
Before you che ck anythi ng in t he eng ine com­
pa rtment, a lways read and heed a ll WARN­
INGS
~ .& in Working in the engine compart­
ment on page 203 .
(D Note
-Before winter se ts in, have the coo lant
checked to see if the coolant additive in your
vehicle is sufficient to meet the c limate con -
Checking and Filling
ditions. This is especia lly important if you
live in a region whe re the winter is extreme­
ly cold. If necessary, increase the propo rtion
of coolant addit ive to
60%.
- Whe n adding coolant additive to your cool­
ing system, remember :
- We recommend us ing o nly coola nt addi­
tive G 12++ or G13 (c hec k the label) for
y o ur vehi cle. Thi s coo lant ad ditive is av ail­
abl e at a uth orized Au di dea le rs. Ot her
types o f ant ifreeze ca n sign ifican tly re ­
d uce corrosion protection. The resu lting
cor ros ion can cause a loss of coolant and
se rious engine damage.
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant . Adding ra­
diator repair fluid may adversely affect the
function and performance of your cooling system and could result in damage not cov ­
ered by your New Veh icle Limited War ra nty .
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance .

Checking and Filling
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 205.
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 15 will il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
electric 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.
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 itto cool down.
- Protect your face, hands and arms from es­ caping 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 spill anti­
freeze or coolant on the exhaust system or
hot engine parts . Under certain conditions,
the ethylene glycol in engine coolant can
catch fire .

(D 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
<::>.& in Working in the engine compartment on
page 203 .
.. Requirement: There must be a residual amount
of coolant in the expansion tank
i:::>Q) .
.. Turn off the engine .
.. Let the engine cool down .
.. Place a thick rag over the coolant expansion
tank <::>
page 209, fig. 186 and carefully twist
the cap counter-clockwise
c::> &,.
.. Add coolant mixed in the correct ratio
<::> page 209, Coolant up to the MAX marking.
.. Make sure that the fluid level remains stable.
Add more coolant if necessary.
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to ex­
act specifications <::>
page 209, 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 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 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 . Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.

,&_ 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 spill ant i­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- 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 professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
i n the cap when the engine becomes hot .
- If, in an emergency, only water can be add­ ed, the correct ratio between water and an­
tifreeze
¢ page 209 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulat ions.

Checking and Filling
Radiator fan
The radiator fan switches on automatically by it­
self .
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢&. , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­ gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
--
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running .
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature drops.
