2015 AUDI A8 child lock

238 Check ing and filling
• Let the engine coo l down .
• Place a thick rag over the coolant expansion
tank
¢ page 237, fig . 204 and care full y
twist the cap counter-clockwise¢ _&..
• Add coolant mixed in the correct ratio
¢
page 236, Coolant up to the MAX mark­
i ng.
• Make sure that the fluid level rema ins sta-
ble. Add more coolant if necessary.
• Twist the cap on again
tightly.
Replacement engine coolant must conform to
exact specifications ¢
page 236, Coolant.
We recommend using only coolant additive
G12++, G13 or in an emergency G12+ . Do not
use a different additive . In an emergency use
p la in water unt il you can get the correct add i­
tive 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 co ld antifreeze
and cold water only when the engine is co ld.
Always use
new eng ine coolant when refilling .
Do not fi ll coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
g ine becomes hot .
A WARNING
- T he coo ling system is under p ressure and
can get very hot. Reduce the risk of
scalding from ho t coolant by following
these steps.
-Turn off the eng ine and a llow it to cool
down.
- Protect your face, hands and arms from escaping flu id and steam by cover ing
the cap with a large, thick rag.
- T urn the cap slowly and very carefully
in a counter-clockwise d irect ion while
apply ing light, downward pressure 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 certa in cond
it ions, the ethylene g lycol in en­
gine coolant can catch fire.
- Antifreeze is poisonous . A lways store an­
tifreeze in its origina l container and well
out of the reach of children.
- If you dra in the coo lant, it must be
caught and safely stored in a proper con­
tainer clearly marked "po ison".
@ Note
- Do not add coolant if the expansion tank
is empty. Air co uld enter the cooling sys­
tem and damage the engine. If this is
the case, do not cont inue driving. Seek
professional assistance .
- Coo lant pollutes the environment and
cou ld cause an engine f ire. Excess cool­
ant will be forced out through 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 co rrect ratio between water
and antifreeze ¢
page 236 must be re­
stored as soon as possible.
@ For the sake of the environment
D rained coolant should not be reused . Al­
ways d ispose of used coolant while observ­
i ng all envi ro nmental regula tions.
Radiator fan
The radiator fan switches on automatically by
itself
The rad iator fan is driven by the e ngine via the
V-belt. The viscous clutch regulates the speed of the fan acco rding to the temperatu re of the
coolant.
An auxiliary electric radiato r fan* sw itches on
and off depending on coolant temperature
and ot her vehicle ope rat ing condit io ns.
After you switch the eng ine off, the aux iliary
fan can continue running for up to 10 m inutes
- even w ith the ignition off .
It can even switch
o n aga in later by itself¢.& , if
