inflation pressure AUDI TT COUPE 2009 User Guide

Tires and wheels -
----------------
•
& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• 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
dealer. •
Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system* to the load you are carrying.

Significant loss of air pressure }
The yellow symbol appears in the event of a significant
loss of air pressure.
Fig. 153 Display:
yellow symbol with message
If the I warning light in the instrument cluster comes on
and then the(•' symbol appears in the display ~ fig. 153,
pressure in at least one tire is too low.
- Stop driving as soon as possible without endangering
yourself and other drivers on the road.
Inspect all tires.
- Change the tire if necessary ~
page 268.
The, warning light in the instrument cluster comes on when the
tire is significantly underinflated .
In addition, the tire symbol
J appears in the display together with
the message Please check tire pressure=> fig. 153. .._

After a few seconds, the message disappears again. If you would
like to show the message again, press the Set/Check button
=>
page 72 , fig. 2@ .
[ i) Tips
• 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 256.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni ­
toring system*=>
page 257. •

Storing tire pressures
Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni­
toring system
In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor­ mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load
conditions, please see chapter
=> page 238. .,_

the Tire Mobility System
Open the lid 0 of the electric air pump:::;, page 266,
fig. 159.
- Pull the plug © and the pressure hose G)with the gauge
out of the housing.
- Screw the pressure hose© of the electric air pump onto
the flange © of the sealant bottle
G).
-Push the sealant bottle with the flange down into the
recess
0 on the lid of the electric air pump.
- Remove the dust cap from the valve of the defective tire.
- Screw the hose@) onto the valve

- Insert the plug©:::;,
page 266, fig. 159 into the socket for
the cigarette lighter.
Inflating tire
- Move the switch®:::;, fig. 160 on the electric air pump
4
l
to position I. After 5 minutes, tire pressure must have
reached at least 1.8 bar.
41 The electric a ir pump should never run for longer than 8 minutes .
-Switch the electric air pump off -switch in position 0. If
the required tire pressure of at least 1.8 bar has not been
reached, follow the instructions in the section
Re-
inflating tire.
Re-inflating tire
- Remove the hose from the valve and pull the plug out of
the socket.
- Drive the vehicle slowly 10 meters backward or forward.
This helps to distribute the sealant better.
- Remove the empty inflation bottle and screw the hose©
:::;, page 266, fig. 159 from the electric pump directly onto
the valve.
- Insert the plug ©:::;,
page 266, fig. 159 into the socket for
the cigarette lighter.
- Move the switch®:::;, fig. 160 on the electric air pump
4
l
to position I. After 5 minutes, tire pressure must have
reached at least 1.8 bar.
- Switch the electric air pump off -switch in position
0. If
the required tire pressure of at least 1.8 bar has not been
reached, it is not possible to make a repair with the tire
sealant. Seek professional assistance.
Disassembling Tire Mobility System
- Remove the hose from the valve and pull the plug out of
the socket.
- Screw the dust cap onto the valve.
- Place the empty sealant bottle back in the original pack-
aging and clip it in place under the floor so that no tire
sealant can run out into the vehicle. .,
