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=>

Deactivating the function
- Briefly press the knob g{!} => fig. 91 so it will stand out

- Turn the knob to position
0.
Push the knob back in to secure its setting.
The coming home/leaving home function is controlled by light
sensors located in the inside mirror housing and stem. The system
is activated if all of the conditions below are fulfilled: •
the knob
lJ has been turned to position 1
• the driving lights and the ignition have been switched off
• the vehicle is parked in poor light or darkness with the sensors
detecting little or no light at all.
Coming home situation
In darkness , the activated system will turn on the front fog lights, tail
lights, and rear licence plate light as soon as the driver's door is
opened from inside.
As long as one of the doors or the rear lid remains open, the set of
external lights will keep burning for about two minutes maximum.
To provide ligh t for departure, the set of vehicle lights will keep
burning for about another 30 seconds after all doors and the rear lid
have been closed.
The factory -set time of 30 seconds until the lights are switched off
can be adjusted if you prefer a longer or shorter duration. Have the
adjustment done by your Audi dealer or a qualified workshop . The
system can be adjusted to keep the lights burning for a maximum
of 60 seconds.
Leaving home situation
As soon as the vehicle is unlocked by pressing the@ button on your
remote control, the set of external lights is switched on .
The external lights are switched off as soon as the driver's door is opened from outside. Even if you had the system readjusted to keep
the lights burning for an extended time for coming home, the
external lights will be turned off if you do not open the driver's door
within 60 seconds after unlocking see chapter "Opening and Closing" in your Owner's Manual. If the lights are switched off
before you reach the driver's door, press them button once more to
turn them on again. .,_

[ 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. •
