2009 AUDI A4 CABRIOLET technical data

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 ] Tips
• The tire pressure is shown on the tire pressure label. On USA
vehic les, the tire pressure label is located on the driver 's side 8-
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side 8 -pi llar or insid e the fuel filler flap . 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 271.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver st ill has t he responsibi lity for
maintaining the correct tire pressure .•

Power top: ca nnot b e use d
Power top not operating
This message wi ll appear in the display if the power top has been
deactivated for safety reasons or if there is a malfunction. Possible
causes are:
• vehicle speed t oo high: the power top operation is deactivated
for safety reasons if the vehic le is mov ing at a speed above 3 mph
(5 km/hi.
• battery voltage too low: the power top wil l not operate if the
battery voltage is too low . This is a precautionary feature to make
s u re that the re is always enough battery power avai lable to start the
engine. The power top can be activated again once the engine has
been started and is running.
• ove rload cut -off: if the power top is operated repeatedly the
hydraulic actuator components will be severely stressed . In this
case the over load cut -off will safeguard the system against damage.
This safeguard deactiva tes the system fo r abou t 15 to 30 minutes.
After this time the power top can be operated again as usual=> & .
• Malfunction: One possible cause of a malfunction is the fai lure
of a system component. In this case the power top can a lso be
manual ly operated =>
page 68. Turning off the ignition during the
opening or closing process may cause a malfunction. You can
correct this yourself=>

[ i J Tip s
• Do not attach any stickers to the windshield in front of the two
light sensors, as this would interfere with both the automatic oper ­
ation of the head ligh ts and the automatic dimming of the inside
mirror(s).
• If the veh icle is remotely un locked and locked
three times in
succession,
leaving home will not turn on the lights a fourth time to
safeguard the battery and lights.
• If you wish to use the coming home/leaving home function regu ­
larly, you can leave it activated at all times wi thout risking perma­
nent strain on the electrical system. As the system is contro lled by
light sensors, i t wi ll only b e energi zed in darkness.
• Frequent use of the coming home/leaving home function for
approac hin g and departing a vehicle parked in the dark wi ll strain
the batte ry. This applies particularly if only short distances are
driven between stops . Occasiona lly drive longer distances to make
sure the battery is recharged sufficient ly.
• If the fo g lights have been switched on by the coming
home/leaving home function, they will always be switched off when
you switch on the ig nition. •
