cooling AUDI RS7 SPORTBACK 2016 User Guide

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.
