-- Always take the vehicle key with you when
leaving the vehicle, even for a short period
of time. This applies particularly when chil­
dren remain in the vehicle. Otherwise the
children could start the engine or operate
electrica l equipment such as power win­
dows .
- Do not remove the key from the ignition
lock until the vehicle has come to a com­
p lete stop. Otherwise, the steering lock
could engage sudden ly and increase the risk
of an accident.
(D Tips
The operation o f the remote control key can
be temporarily disrupted by interference from
transmitters in the vicinity of the vehicle
working in the same frequency range (for ex­
ample, a cell phone or radio equipment).

When switched on, adaptive light adjusts to
curves depending on the vehicle speed and steer­ing 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* (vehicles with adaptive
light) -the cornering light switches on automati­
cally when the steering wheel is turned at acer­
tain angle at speeds up to approximately 44 mph
(70 km/h) and when the turn signal is activated
at speeds up to approximately 25 mph (40 km/
h). The area to the side of the vehicle is illuminat­
ed 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*
(Vehicles with adaptive light or LED headlights) -
This function adapts the lighting for highway
driving based on vehicle speed .
& 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
io.
-Accidents could occur if you cannot see the
road ahead of you well and if others on the
road cannot see you . Always switch your
headlightsonsothatyoucanseetheroad
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 lights may switch off au­
tomatically to conserve the battery charge

for the next time the engine is started. Al·
ways make sure your vehicle complies with
legal regulations regarding sufficient and
safe lighting when parking it. Avoid using
the parking lights for several hours.
- Please observe legal regulations when using
the lighting systems described .
@ 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 functions of the exterior lighting can
be adjusted
¢ page 48 .
-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

Warm and cold
Warm and cold Climate control system
Description
Different systems could be installed.
- manual climate control system* or
- automatic climate control system*
- Plug-in hybrid drive* climate control
¢page 122
The climate control system* cools and removes
humidity from the air in the vehicle interior. It is
the most effective when the windows and panor­
ama sunroof* are closed.
If there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling process. For this reason, the
windows and panorama sunroof can be opened from the outside .
¢ page 43, Convenience open­
ing/closing
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air .
Key recognition
You can store various settings for the manual and
automatic
climate control system* and assign
them to the key being used.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog.
- Become familiar as quickly as possible with
the correct use and function of the cl imate
control system, especially with the defrost­
ing and defogg ing function.
- When the temperature is below freezing,
only use the windshield washer system after
70
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshield and impair visibili­
ty.
Cl) Note
- If you suspect that the climate control sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Audi dealer or authorized
Audi Service Facility.
- Repairs to the Audi climate control system
require special technical knowledge and
special tools. See an authorized Aud i dealer
or authorized Aud i Service Facility .
@ For the sake of the environment
Reducing the amount of fuel used also re­
duces the amount of pollutants that enter the
air.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- Condensation from the cooling system* can
dr ip and form a puddle of water unde r the
vehicle. This is norma l and does not mean
there is a leak.
- Th e energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy supply has been
restored.
- The f lows through the vents under the rear
window. Make sure the openings are not
covered when placing clothing on the lug­
gage compartment cover .
