warning AUDI TT ROADSTER 2008 Owner's Manual

-Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be
the cause of the malfunction.
If the generator warning/indicator light should also illuminate
=> page 19 , then the fan belt may be damaged.
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights
=> page 75, "Emer­
gency flasher A".
• Never open the hood if you see or hear steam or coolant
escaping from the engine compartment -you risk being scalded.
Wait until you can no longer see or hear steam or coolant
escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 212, "Engine compartment".
0 Note
Do not continue driving if the _F_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •

Engine oil pressure malfunction 'l=;:f.
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to result in serious damage to the
engine.
If the ~ symbol appears in the display and flashes, the oil
pressure is too low. In addition to the symbol, the following
message also appears in the display:
SWITCH OFF ENGINE AND CHECK OIL LEVEL
Immediate actions
- Pull off the road and stop the vehicle.
- Shut the engine down.
- Check the engine oil level with the dipstick=> page 224.
Dipstick reading checks too low
- Top off oil to the proper level
=> page 225.
- Make sure that the oil pressure warning symbol ~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the ~ symbol starts flashing again even though the
engine oil level checks OK on the dipstick ,
do not start
driving again and do not let the engine run at idle .
Instead, contact your authorized Audi dealer for assis­
tance.

[ i] Tips
• The engine oil pressure symbol 9:::r. is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication · requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning symbol
9:::r. starts to flash before you respond to the
low oil level warning . By then, your engine may already have
suffered serious damage. •

warning system
Driver inform ation system
The speed warning system warns the driver if he exceeds a previ ­
ously stored maximum speed. A warning tone wi ll sound as soon as
the vehicle speed exceeds the set speed by about 6 miles per hour (10 km/h). At the same time, a warning symbol appears in the
display=> fig. 23.
The speed warning system has
two warning thresholds that func ­
tion independently of each other and that have somewhat different
purposes :
Speed warning 1 )f ..._ (Canada models)
You can use speed warning 1 to set the maximum speed while you
are driving . This setting will remain in effect until you turn off the
ignition, assuming that you have not changed or reset the setting.
The speed warning symbol
J I ,.... (Canada models) in the warning 1
display appears when you exceed the maximum speed . It goes out
when the speed falls below the stored maximum speed.
The speed warning symbol will also go out if the speed
exceeds the
stored maximum speed by more than about 25 mph (40 km/h) for at
least 10 seconds. The stored maximum speed is deleted .

Storing warning 2 is recommended if you always want to be
reminded of a certain speed, for example when you are traveling in
a country that has a general maximum speed limit, or if you do not
want to exceed a specified speed for winter tires.
The speed warning 2 symbol, / ) (Canada models) appears in the
display when you exceed the stored speed limit. Unlike warning 1,
it wi ll not go out until the vehicle speed drops below the stored
speed limit .

Tire pressure monitoring system
General notes
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMS) that illuminates a low tire
pressure telltale when one or more of your tires is significant ly
under -inflated. The TPMS only provides a low tire pressure warning
and does not reinflate your tires.
Accordingly, when the low tire pressure tellta le illuminates, you
should stop and check your tires as soon as possib le, and inflate
them to the proper pressure. Driving on a significantly under­
inflated t ire causes the tire to overheat and can lead to tire failure .
Under -inflation a lso reduces fuel efficiency and tire tread l ife, and
may affect the vehicle's handling and stopping ability.
(D Note
• Please note that the TPMS is not a substitute for proper tire
maintenance, and it is the driver's respons ib ility to maintain correct
tire pressure, even if under -inflation has not reached the level to
trigger illumination of the TPMS low tire pressure telltale .
• Each tire, including the spare, should be checked monthly when
cold and inflated to the inflat ion pressure recommended by the
vehic le manufacturer on the vehicle p lacard or tire inflation pres ­
s u re label. (If your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pressure labe l, you
should determine the proper tire inflation pressure for those
tires.) •
TPMS malfunction indicator
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly . The
TPMS malfunction indicator is combined with the low tire pressure _.,

telltale. When the system detects a malfunction, the telltale will
flash for approximately one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
starts up as long as the malfunction exists .
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
a lternate tires and wheels al low the TPMS to continue to function
proper ly .•
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving.
As soon as the t ire pressure monitoring system senses a s ignificant
loss of air pressure in one or several tires, text messages and yel low
symbo ls appear in the instrument cluster display to a lert the driver.
The warning light in the instrument c luster comes on when the
tire is significantly underinflated
=> page 17.
The warning light
malfunction . also
illuminates in the case of a system
Be aware that tire pressure is also dependent on the temperature of
the tire . For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about 1 .5 psi (0. 1 bar) . The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure on ly when they are
cold , when the temperature of the tires
is roughly the same as the ambient air temperature.
In order to keep the tire pressure monitoring system properly ca li­
brated, tire pressure on all four tires should be checked at regular intervals, adjusted if necessary and saved in the proper setting
(recommended
pressure)=>
page 44.
The tire pressure is shown on the label located on the driver 's side
B -pillar (visible when the door is open) .
& WARNING
• When the tire pre ssure monitor ing system warn ing light i s lit ,
one or more of your t ir es is s ignificantl y unde r-inflated . You should
s top and check your tire s as s oon as po ssible , and inflate them to
the p rope r pre ss ure as indi cated on th e vehicl e's tire pr essure

=> pag e 242. Driv ing on a s ignific antl y un der-inflated t ire
c a use s the tire to overhe at and can le ad to tire fa ilure. Unde r-inf la­
ti on also i s lik el y to impair the vehicle' s handling and stopping
ability .
• Do not adju st t ir e pressur e wh en t ire t emp erature is exce ssiv e.
Thi s could le ad to seriou s tire dam age and even cau se the tire t o
bur st, w ith the addition al dan ger of an accident.
W For the sake of the environment
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i ] Tips
• Each tire should be checked month ly when the temperature of
the tires is abou t the same as ambient air temperature and s et to the
recommended inflation pressure as specified on the tire pressure
label =>
page 242.
• The factory supplied spare whee l is equipped with a se nsor for
the tire pressure monitoring sys tem. As long as the spare wheel is
n ot mounted, the tire pressure of this tire wil l not be monitored.
• T he tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver still has the responsibility f or
maintaining the correct tire pressure . .,_

• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambien t air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged. The valve core, nut, valve sea ling and sea l washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be rep laced .
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dea ler.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure monitoring system to the load you are carrying .•

• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards=> page 44.
• Tire pressure must only be adjusted when the temperature of the
t ires is about the same as ambient air temperature.
• The yellow symbol disappears, when the tire pressure is
corrected and the new pressure is stored in the system=>

• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on a ll wheels. In add ition , you
must then initia lize the new tire pressures in the tire pressure moni ­
toring system =>
