2014 AUDI TT ROADSTER radiator

@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
.,. Turn the ignition key to position @
¢page 73, fig. 82.
_& WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injur ies.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment .
(D Note
Do not stop the engine immediately after
hard or extended driving. Keep the engine
r un ning for approximately two minutes to
prevent excessive heat build-up.

ter to rem ind you to release the parking
brake:
Parking brake set
The parking brake warning comes on only af­
ter you have driven for longer than 3 seconds
and faster than 5 mph (5 km/h) .
The parking brake warning light_
(USA)/ . (CON) illuminates when the park­
ing brake is set and you switch on the ignition .
A WARNING
Always re lease the park ing brake com -
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This
could lead to brake failure and an accident. .,.

166 Checking and filling
-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood.
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under
any circumstances . This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever to "P" (Park) .
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and wear no clothing that will hang or droop into the engine.
- Minimize exposure to emission and chemical hazards~&, .

tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam ­
age to vehicle systems will occur.
@) For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.

172 Checking and filling
@ For the sake of the environment
- Before changing your oil , first make sure
you know where you can properly dispose
of the used o il.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage dra ins.
- Recycle used engine oil by taking it to a
used engine o il collection facility in your
area, or contact a service station .
Engine 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 sea led and generally re­
q uir es little attention .
The cooling system has been filled at the fac ­
tory with a pe rmanent coolant which does not
need to be c hanged. The coolant consists of a
mixture of spec ia lly condi tioned water and the
manuf acturer 's glyco l-b asedcoolan t addi -
tive G l3 antifreeze with ant icorros ion addi ­
tives (50% for USA models ; 60% for Canadian
mod els). This mixture both assures the nec es­
sary frost protection and p rotects metal com ­
ponents in the engine's cooling system from
corrosion and scaling . It a lso raises the boil­
ing point of the coo lant .
Do not red uce the concentration o f the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
l e a st 50 % but not more than 60 %
to main­
tain antifreez e protection and cooling efficien­
cy . If the coolant frost prote ct ion is too low,
the coo lant cou ld free ze and damage the veh i­
cle hea ting and eng ine cooling system.
For yea r-round d riving, antifreeze is added at
the fac to ry for temperatures down to:
-- 31°F( -35°C)USA
- -40 °F ( -40 °C) Canada. If
you must add coolant, use a mixture o f wa ­
ter and coolant additive . Mixing the coo lant
additive with distilled water is recommended.
A WARNING
-
Before you c heck anything in the engine
compartment, always read and heed a ll
WAR NINGS
c::, & in Working in the engine
compartment on page 165.
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ m ate conditions . This is especia lly impor­
tan t if you live in a reg io n wher e the win ­
t er is ex treme ly col d. If ne cessa ry, i n­
crease the proportion of coo lant add itive
t o 60%.
- Whe n adding coolant additive to yo ur
c oolin g sys tem, remembe r:
- We recommend using on ly coolant ad ­
d itive Gl2++ or Gl3 for your vehicle .
This coolant additive is avai lab le at au­
thor ized Audi dealers . Other types of
ant ifre eze can s ignificant ly reduce cor ­
rosion prote ctio n. T he resulti ng cor ro­
sion can ca use a lo ss o f coolan t and se­
rio us en gine d amage.
- Do not add any ty pe of rad iator leak seal­
a n t t o y our vehicle 's engine coolant.
Add ing radiator rep air fl uid may adverse ­
ly affect the function and performance of
yo ur cooling system and co uld resu lt in

Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig. 134 Eng ine compartme nt: cover o n the coolant
expansion tank
Before you check anything in the engine com­
partment,
a lway s read and he ed all WARN ­
INGS ¢ A in Working in the engine compart­
ment on page 165.
.,. Park your vehicle on a level surface.
.,. Switch the ignition
off .
.,. Read the coola nt level at the coolant expan­
s ion tank
¢ page 167, fig . 130. With a cold
engine, it must be above the "min" mark.
With a hot engine, it can be a l ittle above
the indica ted range.
The location of the coolant expans ion tank
can be seen in the engine compar tment illus­
tration
¢page 167.
To obtain an accurate read ing, the eng ine
must be switched
off.
The expans ion tank in your vehicle is equipped
with a n electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System¢
page 17 will
illum inate 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 leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool­
i ng system should be inspected immediately
Checkin g and fillin g 173
by your authorized Audi dea ler . It is not
enough merely to add coo lant .
In a
s ealed system, losses can o ccu r on ly if
the boiling point o f the coo lant is exceeded as
a res ult of overheating.
(D Note
Do not ad d any type of radiator leak sea l­
ant to your veh icle's engine coo lant. Add­
ing radiator repa ir flui d may adverse ly af ­
fect the function and performance of yo ur
cooling system and could result in damage
not covered by your New Vehicle Limited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the engine com ­
partment,
alway s read and heed alt WARN­

engine becomes hot .
.&_ WARNING
-The coo ling system is under pressure and
can get
very hot. Reduce the risk of
sca lding from hot coolant by following
these steps .
- Turn off the eng ine and a llow it to cool
down.
- Protec t your face, hands and arms from
escap ing fl uid and steam by cover ing
the cap with a large, thick rag.
- Tu rn the cap slowly and
very ca refully
in a counter -clockwise direct ion while
applying light, downward p ress ure 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 certain
conditions, the ethylene glyco l in en­
g ine coolant can catch fire.
- Antifreeze is poisonous. Always store an ­
t ifreeze in its or iginal container and we ll
out of the reach of children.
- If you drain the coolant, it must be
caught and safely stored in a proper con­
ta iner clearly marked "poison".
(D Note
- Coolant po llutes the environment and
could cause an engine fire. Excess cool­
ant will be forced out through the pres­
sure re lief
valve in the cap when the en­
gine becomes hot .
- If, in an emergency, only water can be
added, the correct ratio between wate r
and antifreeze~
page 172 must be re­
stored as soon as possib le.
@) For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while obse rv­
ing all environmental regulations .
Radiator fan
The radiator fan switches on automatically by
itself .
The electric radiator fan is controlled by ther­
moswitches that switch on and off depending
on coolant and eng ine compartment tempera­
tures.
An a uxiliary electric radiator fan* sw itches on
and off depending on coolant temperature
and other vehicle operat ion conditions .
After you switch the engine off, the aux iliary
fan can continue running for up to 10 minutes
-even w ith the ignition off. It can even switc h
on aga in later by itself
c> &. , if
- the temperature of the engine coo lant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING
-
- To reduce the risk of personal inju ry nev-
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can sw itch on suddenly
even when the engine is not ru nning.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reac hes a certain t emperature and w ill
continue to run until the coolant temper­
a ture drop s.
