2011 AUDI TT ROADSTER overheating

92 Transmission
-Only use Launch Control when road and
traffic conditions allow it and other driv­
ers will not be endangered or annoyed by
your driving and the acceleration of the
vehicle.
- Make sure that ESP remains enabled.
With the ESP disabled, the vehicle could
brake away, particularly on a slick and
slippery road -risk of skidding!
- Once acceleration is finished, switch ASR
on again by briefly pushing the ESP but­
ton.
Back -up program
In the event of a system malfunction, there is
an back-up program .
In the event of system malfunction, the auto­
matic transmission switches to the fail-safe
mode . All of the selector lever position dis­
plays for the automatic transmission are high­
lighted with a light background in the instru­
ment cluster display . In some cases you can­
not use reverse gear any more.
If the transmission switches to fail-safe
mode, you should take the vehicle to an au­
thorized Audi dealership as soon as possible
to have the condition corrected.
Clutch is overheating
• Clutch is overheating! Please stop vehi­
cle!
If the symbols are illuminated, the clutch is
overheating and could be damaged if you con­
tinue to drive . Stop the vehicle and allow the
transmission to cool with the selector lever in
the
P position while the engine runs at idle. If
the warning does not turn off, do not continue
driving. See your authorized Audi dealer or
qualified repair facility for assistance. Other ­
wise serious transmission damage could re­
sult. Once the indicator light has turned off,
drive to your authorized Audi dealer or quali­
fied repair facility immediately to have the
malfunction corrected.
Selector lever emergency release
If the vehicle 's power supply fails, the selec­
tor lever can be released in an emergency.

150 Intelligent te chn olog y
Noises from the b rake system signal that
wheel spin is being controlled.
Driving off
When drivi ng off, a lways be sure to keep road
conditions in mind as you accelerate. If one
d rive wheel spi ns because it is on a surface
with less grip, gradua lly increase the press ure
on the accelerator pedal until the car starts to
move. The wheel less able to transfer power
spins.
O verheating of bra kes
To prevent the disc brake of the braked wheel
from overheating if subjected to excessive
loads, the EDL cuts out temporarily. The vehi­
cle rema ins operationa l and behaves in the
same way as a vehicle without EDL.
As soon as the brake has cooled down, EDL
switches on again automatically .
A WARNING
-When accelerating on slippery surfaces,
such as on ice or snow, always be careful
when depressing the acce lerator pedal.
Even with the EDL working, the drive
wheels can spin and reduce yo ur ability
to contro l your car. -Risk of crash!
- The increased safety afforded by EDL
does not mean that you can ta ke safety
risks. Always adapt your dr iving sty le to
the road conditions and traff ic situa tion.
@ Tips
If a fa ult occurs in the ABS, the EDL is also
not f unct ion ing. This is indicated by the
ABS warning light ¢
page 17.
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the
driven wheels from spinning wh en the car is
accelerating.
General notes
The Anti-Slip Regulation System (ASR) is inte­
grated in the electronic stabilization program
(ESP). When th e vehicle starts up and acceler- ates, the whee
ls are prevented from spinning
by adjusting the engine power to match the
amount of grip available from the road sur­
face.
How the system works
ASR pe rforms a utomat ica lly, i.e . w ithout t he
driver's intervention. With the aid of the ABS
sensors ¢
page 153, ASR monitors t he speed
of the dr iven whee ls . If the whee ls start to
spin, the engine torq ue is reduced automati­
cally until the tires find enough gr ip to lock
onto the road surface . The system is active
across the ent ire speed range .
The ASR works in conjunction with the ABS. If
a malfunction should occur in the ABS, the
ASR w ill also be out of act io n.
@ Tips
To ensure that the ASR works properly, all
four whee ls must be fitted wit h ident ica l
tires . Any differences in ro lling radius of
the tires can cause the system to reduce
engine power wh en this is not desired. See
a lso
¢ page 205, New tires and repla cing
tires and wheels.

the exhaust system and this could cause
the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not con tinue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reac h the cata lytic converter . This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control
system and cou ld lead to damage.
@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, t he exhaus t gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content o f the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your persona l driving style
- operating conditions
- technical lim itations
I f you anticipate w hat you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 159
fuel consumption by 10 -15 percent. This sec ­
tion w ill give yo u some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as publishe d
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
Avoid unnecessary accelerat ing and braking .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you anticipate what is going to
happe n next, you will need to brake less and,
th us, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
"' Try and keep well below your car's maximum
speed.
Acce lerat ing gently reduces fue l consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at app roximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Nev er drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
T he engine coolan t 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
quires little attention .
T he cooling system has been filled at the fac­
tory with a permanent coolant which does not
need to be changed . The coolan t consis ts of a
mixture of water and the manufacturer 's gly ­
col-basedcoolant additive G12 ++ antifreeze
with anticorrosion additives (50% for USA
models; 60% for Canad ian models). This mix­
ture both assures the necessary frost protec­
tion and protects metal components in the
engine 's cooling system from corrosion and
scaling. It also raises th e boiling point of the
c oolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy . If the coolant frost protection is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, an tifree ze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 5 °C) USA
- -40 °F ( -40 °C) Canada.
You can mix the G12 ++ coolant addit ive with
other additives (G12+ or G12) . Always check
with your authorized Audi dealer.
& WARNING
Before you check anything in the engine
compartment, always read and heed all
-
Checkin g and fillin g 185
WARNINGS c:::> .& in Working in the engine
compartment on page 178.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions. This is especially impor­
tant if you live in a region where the win­
ter is extreme ly cold . If necessary, in­
crease the proportion of coo lant add itive
to 60% .
- Whe n adding coolant additive to your
cooling system, remember :
- We recommend using only coo lant ad­
ditive G12++ (check the labe l) for your
vehicle . This coolant additive is avai la­
ble at authorized Audi dealers. Other
types of ant ifreeze can significantly re­
duce corrosion protection . The result­
ing corrosion can cause a loss of cool ­
ant and ser ious eng ine damage.
- Do not add any type of rad iator leak seal ­
ant to yo ur vehicle's engine coolant .
Add ing radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could resu lt in
damage not covered by your New Vehicle
Limited Warranty .
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

186 Checking and filling
Before you check anything in the engine com­
partment,
alwa ys r ea d and heed all WARN­
INGS ¢ A in Working in the engine
comportment on page 178.
• Switch the ignition off .
• Read the coo lant level at the coolant expan­
s ion tank ¢
fig. 141 . With a co ld engine, it
must be above the "min" mark. W ith a hot
engine, it can be a little above the indicated
range.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration .
To obtain an accurate reading , the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor .
When the coolant level is too low, the warning light in the Auto- Check System ¢
page 31 will
blink until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sen sor, we still rec­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system . In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized A udi 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 result of overheating.
@ Note
Do not add any type of ra diator leak seal­
ant to yo ur vehicle's eng ine coolant. Add ­
ing radiator repair f luid may adversely af­
fect the function 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 anyth ing in the engine com­
partment,
always read and heed all WARN­
INGS ¢ A in Working in the engine comport­
ment on page 178 .
•Turnoff the engine.
• Let the eng ine cool down.
• Place a thick rag ove r the coolant expansion
tank
¢ page 185, fig . 141 and carefully
tw ist the cap counter-clockwise ¢&_ .
• Add coolant.
• Twis t the cap o n aga in
tightly.
Replacement engine coolant must conform to
exact spec ificat ions
¢ page 185, Coolant.
E ven in a n emerge ncy, if coo lant addi -
t ive G1 2++, G12+ or G12 is not ava ilable , do
not use a d ifferen t addit ive. Use plain water
instead unti l you can get the cor rect additive
and can restore the correct ratio . This sho uld
be done as soon as possible .
If you have los t a considerab le amo unt o f
coolant , then you sho uld add cold ant ifreeze
and co ld wate r on ly w hen the engine is cold.
Always use
new engine coo la nt whe n refilling .
Do not fill coola nt above the "MAX" mark. Ex­
cess coo la nt wi ll be fo rced o ut through the

gine becomes hot.
,&. WARNING ~ -
- T he cooling system is under pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by followi ng
these steps.
- T urn
off the engine and allow it to coo l
down.
- Protect you r face, hands and a rms from
esca ping fluid and steam by covering
the cap w ith a large, t hick rag.
- T urn the cap slowly a nd ve ry carefully
