• With the light switch at the O or :oo:: position , only your front fog
lights remain turned on when it turns dark outside . Even though
your instrument s appear well lit, the road ahead of you is not. The
light pattern provided by fog lights alone is not sufficient fo r safe
driving in poor light or darkness. Therefore:
• Always be aware of changes in outside light conditions while
you are driving. Respond in time to fading daylight by turning the
light switch to pos ition

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. •

o ut side weather condit ion s a nd to manually acti vate the wipers a s
soon a s rain or drizzle reduces vi sibility through the wind shield .
• The wind shield mu st not be treat ed w ith water -repellent mate ­
rials. They can increase glare under poor visibility conditions such
a s w etne ss, darknes s, or when the sun i s lo w on t he horizon . In
addition , they can cause the windshield wipers to chatter .
0 Note
In freezing or near freezing conditions :
• Always check that the wiper blades are not frozen to the g lass
before you turn the wipers on. Loosen a wiper b lade which is frozen
in place before operating the wipers to prevent damage to the wiper
b lade or the wipe r motor.
• Do not use the wipers to clear a frosted window . Using the
wipe rs as a convenient ice scraper wil l destroy the wiper blades .
• Before you take your vehicle to an automatic car wash , make sure
you have the wi ndshield w iper system switched off (lever in position
0), otherwise the windshield wiper system could get damaged in the
car wash if it should suddenly come on .
[ i ] Tips
• The rain sensor is part of the interva l wiping system . Turning off
the ignition will also deactivate the rain sensor. To reactivate the sensor, switch off the interva l wiping function, then switch it back
on aga in. • I
f you switch off the ignition with the windshield wiper lever sti ll
in the interva l wipe position and then come back a while late r and
drive off, the rain sensor will reactivate itself after the vehicle speed
has exceeded 4 mph (6 km/h) .
• Worn or dirty windshield wiper b lades cause smearing which
can affect the operation of the rain sensor . Check the condition of
your windshield wiper b lades regularly .
• Make sure the washer fluid reservoir in the engine co mpartment
is topped off before going on a long trip. Look up=>
page 266 for
checking and f illing the washer container .•
