lock until the veh icle has come to a com­
p lete stop. Otherwise, the steering lock
could engage suddenly and increase the risk
of an acc ident.
(D Tips

Opening and clo sin g
Autom atic locking (Auto L ock )
The Auto Lock funct ion locks all doors and the
luggage compartment lid once the speed has ex­
ceeded approximately 9 mph (15 km/h).
The car is unlocked again once the ign ition key is
removed. In addition, the vehicle can be un locked
if the opening function in the power locking sys ­
tem switch is used or one of the door handles is
pu lled .
I n t he event of a crash with airbag deployment,
the doors automat ica lly unlock to allow access to
the v ehicle .
Anti-theft alarm system*
If t he anti- theft alarm system detects a vehicle
b reak-in, a udio and v isua l warning signals are
tr iggered.
The ant i-theft alarm system turns on automati­
cally when you lock the vehicle .
It deactivates
when unlocking using the remote con trol key or
by to uch ing the sensor on the door handle (con­
venience key) .
To sw itch the a la rm off, press the@ button on

28
ing if the most recent ly used key is in the lug­
gage compartment.
Do no t lock your ve hicle w ith the remote cont rol
key or convenience key* until all doors and the

to prevent you from locking yourself out acciden­
ta lly.
{i) Tips

hicle. A locked ve hicle is not a safe!
- If the LED in the upper edge of the drive r's

in the power locking or the anti-theft a larm
system* . Have the problem corrected by an
authorized Audi dealer or authorized Aud i

- The proximity sensor switches off after a
few days to save energy. You then have to
pull once on the door handle to un lock the
vehicle and a second time to open it.
- The energy management system gradually
turns off unnecessary convenience functions
to prevent the battery from dra ining and to

(D Note
- To prevent damage to the power top:
- do not store any objects in the power top
storage compartment.
- make sure there is enough space above
the vehicle when opening or closing the
power top.
- To reduce the risk of damage, make sure
there are no sensitive objects in the power

tion.
(D Tips
- To prevent the battery from draining unnec­
essarily, do not open or close the power top
repeatedly when the engine is switched off.
- A message will appear in the instrument cluster if there is a malfunction in the power
top
~ page 38.
- The power top can also be operated manual­ ly temporari ly if there is a malfunction

Lights and Vision
When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­
ing wheel angle. This provides better lighting
through the curve. The system operates in a
speed range from approximately 6 mph (10 km/
h) to 68 mph (110 km/h) .
Static cornering light* -the cornering light
switches on automatically when the steering
wheel is turned at a ce rtain angle at speeds up to
approximately 44 mph (70 km/h) and when the
turn signal is activated at speeds up to approxi­
mately 25 mph (40 km/h) . The area to the side of
the vehicle is illuminated better when turning.
Speed dependent light distribution* -The speed
dependent light distribution adapts the light in
towns and on highways or expressways . Intersec­
tions can also be illuminated on vehicles with a
navigation system* .
Highway light function*
This function adapts the lighting for highway
driving based on vehicle speed .
A WARNING
-Automatic headlights* are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head­
lights and to turn them on manually accord­
ing to the current light and visibility condi­
tions. For example, fog cannot be detected by the light sensors . So always switch on the
low beam under these weather conditions
and when driving in the dark ~D.
- Accidents could occur if you can not see the road ahead of you well and if others on the
road cannot see you . Always switch your
headlights on so that you can see the road
ahead of you and others can see your vehicle
from behind.
- The rear fog lights should only be turned on
in accordance with traffic regulations, to
prevent glare for traffic behind your vehicle.
-If the battery has been discharging for a
while, the parking light may switch off auto­
matically. Always make sure your vehicle is
parked and adequately lit according to the
44
laws. Avoid using the parking lights for sev­
eral hours.
- Please observe legal regulations when using
the lighting systems described.
(D Tips
- The light sensor for the automatic head­
lights* is in the rearview mirror mount.
Therefore , do not place any stickers in this
area on the windshield.
- Some exterior lighting functions can be ad­
justed
Q page 45.
- If you turn off the ignition while the exterior lights are on and open the door, you will
hear a warning tone.
- In some market-specific versions, the tail
lights do not turn on when switching on the
daytime running lights .
- In cool or damp weather, the inside of the
headlights, turn signals and tail lights can
fog over due to the temperature difference between the inside and outside. They will
clear shortly after switching them on . This
does not affect the service life of the light­
ing.
-A message will appear in the instrument
cluster if there is a malfunction in the light
sensor

@ - Front w ipers off
@ -interval mode. To increase/decrease the wip­
er intervals, move the sw itch @ to the left/right .
In vehicles with a light/rain sensor*, the w ipers
turn on when it is raining, when the vehicle is sta­
tionary and the lever is tapped in the ® position ,
or once the vehicle speed exceeds approximately
2 mph (4 km/h). The h igher the sensitivity of the
rain sensor is set (switch @ to the right), the ear­
lier the windshield wipers react to moisture on
the w indshield .
Lights and V ision
@ -slow wiping
@ -fast wiping
@ -single wipe . If you hold the lever in this posi­
t ion longer, the wipers switch from slow wip ing
to fast wiping .
® -clean the windshield . To e liminate water
droplets after switching the windshield wipers
off while dr iv ing, they w ill operate one more time
severa l seconds afte r switching them off if the
temperature is above approx imately 39 °F (4 °C) .
You can switch this funct ion off by moving the
lever to posi tion ® withi n 10 seconds of the af­
terw ipe. The afterwipe function is reactivated the
next time you switch the ignition on.
A WARNING
-
-The rain sensor is on ly intended to assist the
driver. The driver is still respons ible for
manually switching the wipers on according
to the visibility cond itions .
- The windsh ield may not be treated w ith wa­
ter-repelling w indshield coating agents. Un­
favorable condit ions, such as wetness, dark­
ness, o r when the sun is low, can cause a
strong glare which increases the risk of an
accident. Wiper blade chatter is also possi­
b le.
- Properly functioning windshield wiper
b lad es are required for a clear view and safe
driving
~ page 50, Replacing front wind­
shield wiper blades.
(D Note
-If there is frost, make sure the windshield
w iper blades are not frozen to the wind­
shield. Switching on the windshie ld w ipers
when the blades are frozen to the wind­
shield can damage the w iper blades.
- Prior to using a car wash, the windshield
w iper system must be switched off (lever in
position @). This prevents unintentional
switching on and damage to the windsh ield
wiper system .

@ Tips
-The windshield wipers switch off when the
i gnition is turned off . You can activate the
windsh ield wipers after the ign ition is
switched back on by moving the windsh ield
wiper lever to any pos it ion.
- Worn or dirty windshield wiper blades result
i n streak ing. This can affect the ra in sensor
funct ion . Check your windshield wiper
blades regularly.
- The washer fluid nozzles in the w indshield
washer system are heated* at low tempera­
tures when the ignition is on .
- When stopp ing tempora rily, such as at a
traffic light, the speed of the windshie ld
wipers automat ically reduces by one leve l.
- In vehicles with an MMI, you can switc h the
rain sensor on or
off in the Dr iver a ssistance
menu.
