Climate control system
Description
Different systems cou ld be installed.
- manual climate control system* or
- automatic climate control system*
The
clim ate co ntrol system * cools and re­
moves humidity from the air in the vehicle in­
terior. It is the most effective when the win­
dows and panorama 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
r::} page 3 9, Convenience opening/
closing.
The pollutant filter removes pollutants such
as dust and pollen from the air .
A WARNING
Reduced visibility is dangerous and can
cause accidents.
-
- For safe dr iv ing it is very important that
all windows be free of ice, snow and con­
densation.
- Completely fami liarize yourself with the
proper use and function of the heating
and ventilation system and especia lly
how to defog and defrost the windows .
- Never use the windshie ld w iper/w asher
system in freezing weather until you
have warmed the windshield first, using
the heat ing and ventilation system . The washer sol
ution may freeze on the wind­
shie ld and reduce visib ility.
@ Note
- If you suspect that the air conditioner
has been damaged, switch the system
off to avoid further damage and have it
inspected by a q ualified dealership.
- Repairs to the Audi air conditioner re­
quire specia l technical know ledge and
special tools. Contact an authorized Aud i
dealer for ass istance.
@ For the sake of the environment
By reducing the amount of f uel you use,
you also reduce the amount of pollutants
emitted into the air.
(1) Tips
- To prevent interference with the heat ing
and cooling output and to prevent the
w indows from fogging over, the air in­
take in front of the windshield must be
free of ice, snow or leaves.
- Condensation from the cooling system*
can drip a nd form a puddle of wa ter un­
der the vehicle . This is normal and does
not mean t here is a leak.
- The energy ma nagement system may
switch the seat h eating* or rear window
defroster off temporar ily. These systems
are available again as soon as the energy
balance has been resto red.
- Air escapes through vents under the rear
w indow. When plac ing items of cloth ing
on the luggage compartmen t cover, en ­
sure t hat the openings are not covered .

66 Warm and cold
Foot vents are located under the front seats
to heat the rear of the vehicle.
l= I Switching recirculation mode on and
off
I n recirculation mode, the air inside the vehi­
cle is circu lated and filtered. This prevents the
unfiltered air outside the vehicle from enter­
ing the vehicle interior. We recommend
switching recirculation mode on when driving
through a tunnel or when sitt ing in traffic

Speed warning system
Introduction
The speed warning system helps you to stay
under a specified maximum speed.
The speed warning system warns you if you
are exceeding the maximum speed that you
have set. You will hear a warning tone when
your speed exceeds the stored value by ap­ proximately 3 mph (3 km/h). An indicator
light . (USA models) . (Canada models) in
the instrument cluster display also turns on at
the same time. The indicator light./.
turns
off when the speed decreases below the
stored maximum speed .
Setting a threshold is recommended if you
would like to be reminded when you reach a
certain maximum speed. Situations where you may want to do so include driving in a country
with a general speed limit or if there is a
specified maximum speed for winter tires .
@ Tips
Even though your vehicle is equipped with
a speed warning system, you should still
watch the speedometer to make sure you
are not driving faster than the speed limit.
Setting the threshold
You can set, change and delete the threshold
in the MMI.
"' Select: Systems or Car systems > Driver as­
sist> Speed warning .
Driving 79
You can set any threshold between 20 mph (30 km/h) and 150 mph (240 km/h). Settings
can each be adjusted in increments of 6 mph
(10 km/h).
Cruise control system
Description
Applies to vehicles: with cruise control system
The cruise control system makes it possible to
drive at a constant speed starting at 15 mph
(20 km/h).
The speed is kept constant by modifying en­
gine power or through an active brake inter­
vention.
.&_ WARNING ~
- Always pay attention to the traffic
around you when the cruise control is in
operation. You are always responsible for
your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop­
and-go traffic, on winding roads and
when road conditions are poor (such as ice, fog, gravel, heavy rain and hydro­
planing) -you could have an accident.
- Switch the cruise control
off temporarily
when driving in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal pre­
vents the cruise control from braking.
This is due to the control system being
overridden by the driver's acceleration.
- If a brake system malfunction such as
overheating occurs when the cruise con­
trol system is switched on, the braking
function in the system may be switched
off. The other cruise control functions re­
main active as long as the indicator light
II (US models) !l'I (Canadian models)
ison.

82 Audi adaptive cruise control
Audi adaptive cruise
control
Introduction
Ap plies to vehicles: with Audi adaptive cruise co ntrol
The adaptive cruise control system is a combi­
nation of speed and distance regulation. It as­
sists the driver by both regulating the speed
and maintaining a distance to the object
ahead, within the abilit ies of the system. If
the system detects an object, adaptive cruise
con trol can brake and accelerate your vehicle.
This together with the automatic transmis ­
sion* makes driving more comfortable both
on long stretches of highway and in stop-and­
go traffic.

The general information applies to adaptive
cruise control* and pre sense front*
c:>page90.
The radar sensor area c:>fig. 70 must not be
covered with stickers, deposits or any other
obstructions as it may impair the function of
the adaptive cru ise control and the pre sense
front. For information on cleaning, see
c:> page 201 . The same applies for any modifi­
cations made in the front area .
The function of the adaptive cruise control
system and pre sense front is limited in some
conditions: -
Objects can only be detected when they are
within the sensor range
c:> page 84,
fig. 73.
-The system has a limited ability to detect
objects that are a short distance ahead, off
to the side of your vehicle or moving into
your lane.
- Objects that are difficult to detect such as
motorcycles, vehicles with high ground
clearance or an overhanging load are detect­
ed late or not detected at all.
- When driving through curves
c:> page 83.
-With stationary objects r=;, page 83 .
A WARNING
-
Always pay attent ion to traffic when adap­
tive cruise control is switc hed on and the
pre sense front is active
c:> page 90. As
the driver, you are still responsible for
start ing and for maint.;1 ining speed and
distance to other objects. The pre sense
front is used to assist you. The driver must
always take action to avoid a collision. The
driver is always responsible for braking at
the correct time.
- I mp roper use of adaptive cruise con trol
can cause collisions, other accidents and
serio us personal injury.
- Incorrect use of the adaptive cruise con­
trol can cause collisions, other acc idents
and serio us personal injury.
- Incorrect use of the adaptive cruise con­
trol can cause collisions, other accidents
and serio us personal injury.
- For safety reasons, do not use adaptive
cru ise control when driv ing on roads with
many curves, when the road surface is in
poor condition and/or in bad weather
(such as ice, fog, gravel, heavy ra in and
hydroplaning). Us ing the system under
these conditions could result in a colli­
sion .
- Sw itch adaptive cruise contro l off tempo­
ra rily when driving in turning lanes, on
expressway ex its or in construction
zones. This preven ts the vehicle from ac­
celerating to the set speed when in these
situations .

90 Audi pre sense
Audi pre sense
Introduction
Applies to vehicles: with Audi pre sense basic or Audi pre
sense front
Within the limits of the system, pre sense ba­
sic and pre sense front can initiate steps to
protect vehicle occupants in certain danger ­
ous situations.
Critical driving situations can be recognized by
the pre sense front via a network of different
vehicle systems and can take steps to prepare
the vehicle occupants for a potential collision.
The pre sense front works with a radar sensor
and a video camera*.
It also functions within
the limits of the system when adaptive cruise
control* is switched
off.

Audi pre sense basic
Descript ion
Applies to vehicles: with Audi pre sense basic
The function of the pre sense basic is activat­
ed at a speed of 10 mph (30 km/h) or higher.
The following functions can be triggered un­
der certain conditions within the limits of the
system:
- Tensioning of the safety belts (for example,
during heavy braking) : The front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to trigger again .
- Closing the windows and the sunroof* (for
example, when over- or understeering): The
windows and the sunroof" close until there is only a small gap open. Audi drive select:
The deployment time is
adapted in dynamic mode.
A WARNING
-The pre sense basic cannot overcome natu- ral physical laws.
It is a system designed to
assist and it cannot prevent a collision. Do not let the increased safety provided
tempt you into taking risks. This could in­
crease your risk of a collision.
- The system can deploy incorrectly due to system-specific limits .
(D Tips
-Certain pre sense basic functions switch
off when ESC is switched off (sport
mode) or when driving in reverse .
- The pre sense basic functions may not be
available if there is a malfunction in the
ESC system or the airbag control mod­
ule .
- Note that with pre sense basic, the rever­
sible safety belt pretensioner on the
front passenger's side deactivates when
the front passenger's a irbag is deactivat­
ed.
Audi pre sense front
Description
Applies to vehicles: with Audi pre sense front or Audi
adapt ive cru ise control
Pre sense front informs you if the distance to
the vehicle ahead falls below the safe distance
for an extended period of time. It can warn of a possible collision and initiate braking ma­
neuvers, within the limits of the system .
When detected in time, the system can assess
dangerous situations where an object ahead
brakes suddenly or if your own vehicle is trav­
eling at a high speed and approaching an ob ­
ject that is moving more slow ly . If detection is
not possible, then pre sense front does not re ­
act.
