2015 AUDI A5 CABRIOLET ESP

Warm and cold
Warm and cold Climate control system
Description
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 pow­
er top are closed.
If there is a build-up of heat in­
side the vehicle , ventilation can help to speed up
the cooling process.
In all heating mode functions except
defrost, the
blower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture.
Condensation from the cooling system can drip
and form a puddle of water under the vehicle.
This is normal and does not mean there is a leak.
Pollutant filter
The pollutant filter removes pollutants such as
dust and pollen from the air.
The air pollutants filter must be changed at the
intervals specified in your Warranty & Mainte­
nance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter may need to be changed
more frequently than specified in your Audi War­
ranty
& Maintenance booklet. If in doubt, ask
your authorized Audi Service Advisor for advice.
Key coded settings
The climate control settings are automatically
stored and assigned to the remote control key
that is in use . These settings are different when
the power top is open or closed.
_& WARNING
Reduced visibility is dangerous and can cause
accidents.
68
- For safe driving it is very important that all
windows be free of ice, snow and condensa­
tion.
- Completely familiarize yourself with the
proper use and function of the heating and
ventilation system and especially how to de­
fog and defrost the windows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­
ing and ventilation system . The washer solu­
tion may freeze on the windshield and re­
duce visibility .
(U;) 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 qualified dealership.
- Repairs to the Audi air conditioner require
special technical knowledge and special
tools. Contact an authorized Audi dealer for
assistance.
@ For the sake of the environment
By reducing the amount of fuel you use, you
also reduce the amount of pollutants emitted
into the air.
(D Tips
- Keep the air intake slots (in front of the
windshield) free from ice, snow and debris in order to maintain the proper function of
the climate control system.
- The energy management system may switch
the seat heating* or rear window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- Air escapes through vents under the rear
window. When placing items of clothing on
the luggage compartment cover, ensure
that the openings are not covered.

A 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.
Driving
- For reasons of safety , cruise control should
not be used in the city, in stop-and-go traf­
fic, on twisting roads and when road condi­
tions are poor (such as ice, fog, gravel, heavy ra in and hydroplaning) - risk of acci­
dent .
- Turn off the cruise control temporarily when entering turn lanes , highway exit lanes or in
construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is be­
cause the cr uise control is overridden by the
driver's accele rat ion.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off . The other
cruise control functions remain active as
long as the ind icator
light til;rnM4 (US mod­
els)

Audi adapt ive cru ise control and brak ing gu ard
Audi adaptive cruise
control and braking
guard
Introduction
App lies to veh icles: w ith Audi adaptive cruise co ntrol
The adaptive cruise control system assists the
d river by regu lating veh icle speed and he lp ing to
maintain a set distance to the vehicle ahead,
within the limits of the system. If the system de­
tects a moving vehicle up ahead, adaptive cruise control can brake and then accelerate your vehi ­
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an impending collision and initiate brak ing maneu­
vers
c> page 96.
Adapt ive cruise control and braking guard have
technical limitations that you must know, so p lease read this section carefully, understand
how the system works and use them properly at
all times.

The function of the adaptive cruise contro l sys­
tem and braking guard is limited under some
cond it ions:
- Objects can on ly be detected when they are
within sensor range
,=;, page 92, fig. 106.
- T he system has a limi ted ability to detect ob­
jects that are a short d istance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles are hard to detect; for
example motorcycles, vehicles with high
ground clearance or overhanging toads may be
detected when it is too late or they may not be
detected at all.
- When driving through curves
c::> page 91 .
- Stationary objects c::> page 91.
& WARNING
-Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re ­
sponsible for starting and for maintaining
speed and distance to other objects. Braking
guard is used to assist you . The driver must
a lways take action to avo id a collis ion. The
driver is always responsible for braking at the
correct t ime.
- I mprope r use of adaptive cru ise con tro l can
cause collisions, o ther accidents and serious
personal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and brak ing guard
offer distrac t you from the need to be alert
to traffic cond it ions and the need to remain
in fu ll control of your vehicle at all times,
- Always remember that the adaptive cruise
contro l and brak ing guard have limits - they
will not slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped in a traff ic jam, a stalled or disab led vehicle.
If registered by the radar sensor, vehicles or
obstacles that are not moving can trigge r a
co llision warning and if confirmed by the
video camera, a n acute collision warning.

Audi adapt ive crui se cont rol and bra king gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condit ion and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydroplan­
ing) . Us ing the system under these condi­
tions co uld resu lt in a collision.
- Switch adaptive cruise control off tempora­
rily when driving in turning lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from acce lerating to
the set speed when in these situations.
- T he adapt ive cruise con trol system w ill not
brake by itself if you put your foot on the ac­
celerator pedal. Do ing so can override the
speed and distance regulation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function .
- The adaptive cruise control system and brak­
ing guard do not react to people, anima ls,
objects cross ing the road or oncoming ob­
jects.
- The function of the radar sensor can be af­
fected by reflective objects such as guard
rails, the entrance to a tunnel, heavy rain or
ice.
- Never follow a ve hicle so closely that you
cannot stop your vehicle safely. The adap­
t ive cr uise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
au tom atic b ra ki ng function cannot bring the
vehicle to a su dden or emergency stop un­
der these conditions.
- T o prevent unin tended operation, always
swit ch ACC
off when i t is not be ing used .
(D Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and
underbody. That could affect the adaptive
cru ise cont ro l system and braking guard. Have

In curves
Applies to vehicles: wit h Audi adapt ive cr uise contro l
Fig. 104 Example : driv ing into a curve
When driving into a curve c:> fig. 104 and out of a
curve, the adaptive cruise control may react to a
vehicle in the next lane and apply the brakes. You
can override or prevent the braking by press ing

already detected as moving. For example, if a ve­
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to
t h e stat ionary vehicle.

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to veh icles: w ith Audi adaptive cruise co ntrol
Fig. 113 Instrument cluster : approach warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­
tive cruise control is switched off.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own vehicle is traveling at a high speed
and approaching a vehicle up ahead that is mov­
ing more slowly . Braking guard does not react if it
cannot detect the situation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If the
vehicle ahead brakes sharply, you will not be
able to avoid a collision. The indicator light.
in the display comes on .
- The
approach warning is given when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is given, it may only be pos­
s ib le to avoid a collision by swerving or braking
sharply. The indicator light . and indicato r in
the display will wa rn you about the danger
¢ fig. 113 . You will also hear an acoustic signa l.
If you do not react fast enough or do not react at
all to the situation, Braking guard will intervene
by braking and the message
braking guard inter­
vention
will appear.
ll Thi s is not available in so me c oun tries.
96
- If a co llision is imminent, the system wi ll first
provide an
acute warning by br iefly and sharply
app ly in g the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the vehicle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a complete deceleration shortly be­
fore a collisionl l_
-If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio or MMI
¢page
97, Settings in the radio/MM!.
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious personal injuries. The
braking guard is an assist system and cannot
prevent a coll is ion by itself. The dr iver must
always intervene. The driver is always respon­
sib le for braking at the correct time.
- Always pay close attent ion to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take com­
plete control whenever necessary. Always
keep the safe and legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­
fic).
- Always remember that the radar sensor for
the braking guard works only w ith in defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
