overheating AUDI TT ROADSTER 2014 Owners Manual

_& WARNING
-Always adapt your driving to the traffic
flow.
- 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 ESC remains enabled .
With the ESC disabled, the veh icle could
brake away, particularly on a slick and
slippery road -risk of skidding!
- Once acce lerat ion is finished, switch ASR
on again by briefly pushing the ESC but­
ton.
@ Tips
- The transm ission temperature may in­
crease significantly after using the
Launch Control Program. If that hap­
pens, the program may not be available
for a few minutes. I t will be availab le
again after a coo l-down period.
- When accelerating using the Launch
Control program, all vehicle parts are
subject to heavy loads . This can result in
increased wear.
Back-up program
Applies to vehicles: with S tronic
In the event of a system malfunction, there is
a back-up program.
I n the event of system mal func tion, the auto­
matic transmission switches to the fail-safe
mode. A ll 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.
Transmission 87
Clutch is overheating
Applies to vehicles: with S tronic
• 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 a llow the
transmission to cool with the se lector lever in
the P posit ion while the engine runs at idle.
If
the warning does not turn off, do not continue
driving. See your authorized A udi 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 repa ir facility immed iately to have the
malfunction corrected.
Selector lever emergency release
Applies to vehicles: wi th S tronic
If the vehicle's power supply fails, the selec ­
tor lever can be released in an emergency.

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢

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 continue to operate yo ur vehicle
under these conditions, as otherw ise fuel
can reach 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 intained properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
&
Ma intenance booklet.
- La ck of proper main tenance 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
E ven when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfur -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 it h lead-free super
grade gasoline.
Shutting down vehicle
If you wou ld like your veh icle to remain inop­
erat ive for a longer period of time, contact an
Aud i or other specialized dealer . T hey ca n ad­
vise you on necessary precautions e.g . corro­
sion prevent ion, ma intenance and storage.
Pay atten tion to add it iona l information con­

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, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- oper ating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 1O-lS percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONME NTAL PROTEC TION AG ENCY
( EP A) and Transpo rt Canada may no t corre­
spond to your actual consumption on the
r oad, which will va ry depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they ore ac­
celerating.
Avoid unnecessary acce lerating and braking .
Vehicles use the mos t fu el when they are ac­
ce le rat ing. If yo u ant icipate what is going to
happen next, you will need to brake less and,
t hu s, acce le rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

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,
