-Keep children away from the engine com­
partment.
- Never spill fluids on a hot engine. These flu­
ids (such as the freeze protection contained
in the coolant) can catch fire .
- Avoid short circuits in the e lectrical system,
especially the battery.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm. The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed w ith the en­
gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
t he high vo ltage ig nition system.
- Never reach into the radiator fan . The e lec­
t ric a uxiliary fan is cont rolled by tempera­
t ur e and can switch on sudde nly.
- Pay atte ntion to the fo llow ing warnings list­
ed when wo rk on the fuel system or on t he
ele ct rical eq uipment is requ ired.
- Always d isconnect the ve hicle battery
from the vehicle electrical system
- Do not smoke
- Never work near open flames
- Always have a working fire ex tinguisher
nearby
- T o red uce the risk of e lec tric shoc k and in­
jury, neve r touch the followi ng components
when the eng ine is r unning or is being star t­
ed :

Cooling system
Coolant
The engine coo ling system is filled wi th a mixture
of purified water and coolant additive at the fac ­
tory. This coo lant must not be not changed.
The coolant leve l is moni to red throug h the . in ­
d icator light
q page 16 . Howeve r, we do recom­
mend occasiona lly checking the coo lant level
manually.
If you m ust add coo lant, use a m ix ture of water
an d coolant addit ive. Mixing the coolant additive
with d isti lled water is recommended.
Coolant additive
The coolan t additive is made of anti-freezing and
corros ion pro tection agents. Only use the fol low­
in g coolant add it ives. The se addi tives may be
mixed wit h each other.
Coolant additive Specification

G12 ++ TL 774 G
T he amount of coo lant additive that needs to be
mixed with water depends on the climate where
the vehicle will be ope rated. If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the eng ine.

-
Before the start of w inte r, have you r auth or­
ized Aud i dealer or a uthorized Aud i Serv ice
Facility check if the coolant addit ive in your
vehicle matches the pe rcentage appropriate
for the climate. This is especially important
when driving in colder climates .
- If the appropr iate coo lant add itive is not
availab le in an emergency, do not add any
other additive. Yo u could damage the en­
gine. If this happens, on ly use water and re­
store t he corre ct m ix tu re ratio with the
specified coolant ad ditive as soon as poss i­
ble.
- O nly refill w ith new coolant.
- Radiator sea lant must not be mi xed with

slowly a nd kee p lig ht pressu re o n the cap .
- T o reduce the risk of burns, do not allow any
an tifreeze o r coolant to drip on to the ex­
haus t sys tem or hot engine components.
T he ethylene glycol in eng ine coolan t can
catch fire under certain circumstances .
- T he coo lant add itive an d the cool ant can be
dange rous to you r healt h. For this reason,
keep the coolant in the o rigina l container
away from c hildren. There is a risk of poi­
soning .
- When working in the engine compartment,
remember that the rad iator fan can switch
on even if the ign ition is switched off, which
increases the risk of personal injury .

(D Note
Do not add coo lant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the eng ine. If this is the case, do not
continue driving. See an author ized Audi deal­
e r o r a uthorized Audi Serv ice Facility fo r ass is ­
tance .
Radiator fan
The radia tor fan switches on au tomatically by it­
self.
An a uxiliary e lectric radiator fan switches on and
off depend ing on coo lant temperature and other
vehicle ope rating conditions .
After yo u switch the engine off, the auxiliary fan
can continue running for up to 10 m inutes - even
with the ignit ion off.
It can even switch on aga in
l ate r by itself ¢.& , if
- the temperat ure o f the eng ine coolant rises due
to the heat build- up from the engine in the en­
gine compartment, or
- the engine compartment heats up because the veh icle is parked in intense s unlight.
_& WARNING
- To reduce the r isk of personal injury never
to uch the radiator fan .
- The auxiliary e lectric fan is temperature
controlled and can switch on suddenly even
when the engine is not ru nning .
- The auxiliary radiator fan switches on auto­
mat ica lly when the eng ine coolant reaches a
certain temperature and will continue to run
until t he coo lant tempe rature d rops.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It i s becom ing increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are ab le to get to the bulb.
This applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
