& WARNING
- Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- The rear fog lights should only be turned
on in accordance with traffic regulation,
as the lights are bright for following traf­
fic.
- Please observe legal regulations when using the lighting systems described .
@ Tips
-The light sensor* for automatic head­
light range control* is located in the rear
view mirror mount . You should therefore
not apply any st ickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display
Q page 2 3 .
-You will hear a warning tone if you open
the driver door when the exterior lights
are switched on.
- In cool or damp weather, the inside of
the headlights, turn signa ls and tail
lights can fog over due to the tempera­
ture difference between the inside and
outside. They will clear shortly after
switching them on. This does not affect
the service life of the lighting.
Emergency flasher
T he emergency flasher makes other motorists
aware that you or your vehicle are in an emer­
gency situation .

ment cluster, as well as the light in the emer­
gency flasher switch~ blink likewise. The
emergency flashers also work when the igni­
tion is turned off.
The emergency flashers will turn on automati­
cally if you are in an accident where the airbag

km/h) or switch the ignition
off.
.&_ WARNING
--
-Curved (i.e. convex) mirror surfaces in-
crease your field of view. Remember that
vehicles or other objects will appear
smaller and farther away than when seen in a flat mirror. If you use this mirror to
estimate distances of following vehicles
when changing lanes, you could estimate
incorrectly and cause an accident.
(D Note
-If the mirror housing is moved uninten­
tionally (for example, while parking your
vehicle), then you must first fold the mir­
ror electrically. Do not readjust the mir­
ror housing manually. You could damage
the motor which controls the mirror.
- If you wash the vehicle in an automatic
car wash, you must fold the exterior mir­
rors in to reduce the risk of damage to
the mirrors. Never fold power folding ex­
terior mirrors* by hand . Only fold them
in and out using the power controls.

Warm and cold Climate controls
Description
App lies to vehicles: with three -zone cl imate contro l or
four -zone a uto mat ic climate contro l
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effective when the windows and
sunroof* are closed . If the temperature inside
the parked veh icle becomes very warm, open­
i ng the w indow br iefly will speed up the cool­
ing process.
In all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensat ion from the cooling system can
drip and form a puddle of wate r under the ve­
h icle. This is normal and does not mean there
is a leak .
Pollutant filt er
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals specified in your Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work .
If you drive your vehicle in an area with high
a ir pollution, the filter may need to be
changed more frequently than specified in
your Aud i Warranty
& Ma intenance booklet. If
i n doubt, ask your authori zed Audi Service Ad­
visor for adv ice.
K ey coded settings
Three-zone climate control: T he b lower set­
ting and air d istribution are stored automati­
cally and ass igned to the remote control key
that is in use .
Four-zone automatic climate control: The cli­
mate contro l settings are automatica lly stor­
ed and assigned to the remote control key
that is in use .

emitted into the air.
(D Tips
- Keep the air intake s lo ts ( in front of the
w indshield) free from ice, snow and de­
bris in order to maintain the proper func­
tion of the climate control system.
- The energy ma nagement system may
switch the seat heating* or rear window defroster off temporar ily. These systems
are available again as soon as the energy
balance has been restored .
- Air escapes through vents under the rear window. When plac ing items of cloth ing

sure that the openings are not covered.

98 Audi side assist
-Improper reliance on the side assist sys­
tem can cause collisions and serious
personal injury:
- Never rely only on side assist when
changing lanes.
- Always check rear view mirrors to make
sure that it is safe to change lanes.
- Side assist cannot detect all vehicles un­
der all conditions- danger of accident!
- Please note that side assist indicates
there are approaching vehicles, or
vehicles in your blind spot, only after
your vehicle has reached a driving speed
of at least 19 mph (30 km/h).
- In certain situations, the system may not
function or its function may be limited.
For example:
- if vehicles are approaching or being left
behind very quickly . The display may
not turn on in time.
- in poor weather conditions such as
heavy rain, snow or heavy mist .
- on very wide lanes, in tight curves or if
there is a rise in the road surface.
Vehicles in the adjacent lane may not be detected because they are outside
of the sensor range.
(D Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. This can affect the system.
Have your authorized Audi dealer or au­
thorized Audi Service Facility check their
function.
@ Tips
- If the window glass in the driver's door
or front passenger's door has been tint­ ed, the display in the exterior mirror may
be misinterpreted.
