7 4 Warm and cold
Warm and cold Climate controls
Description
The climate control system warms, cools and
adds humidity to the air in the vehicle interior.
It is the most effect ive when the windows and
sunroof* are closed . If the temperature inside
the parked vehicle becomes very warm, open­ ing the window briefly will speed up the cool­
ing process.
I n all heating mode functions except
defrost,
the blower on ly switches to a higher speed
once the engine coolant has reached a certain
temperature.
Condensation from the cooling system can
drip and form a puddle of water under the ve­
hicle. This is normal and does not mean there
is a leak.
Pollutant filter
The pollutant filter removes pollutants such
as dust and po llen from the air.
The air pollutants filter must be changed at
the intervals spec ified in you r Warranty
&
Maintenance booklet, so that the air condi­
tioner can properly work.
I f you drive your vehicle in an a rea with high
a ir po llution, the filter may need to be
changed more frequent ly than specified in
your Aud i Warranty
& Maintenance booklet. If
in doubt, ask your authorized Audi Service Ad­
visor for advice .
Key coded settings
The climate control settings are a utomat ically
stored and assigned to the remote control key
that is in use.
A WARNING
Reduced visibility is dangerous and can
cause accidents. -
- For safe driving it is very important that
all windows be free of ice, snow and con­
densation.
- Comp letely familiarize yourself with the
proper use and function of the heating
and ventilation system and especially how to defog and defrost the windows.
- Never use the windshield wiper/washer
system in freez ing weather unt il you
have warmed the windshield first, using
the heating and ventilation system. The
washer solution may freeze on the wind­ sh ie ld and reduce visib ility.
(D 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 re­
quire special technical knowledge and
special tools. Contact an authorized Aud i
dea ler fo r 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 s lots (in fro nt of the
w indshield) free from ice, snow and de ­
bris in order to maintain the proper func­
tion of the climate control system.
- T he energy management system may
switch the seat heating* or rear window
defroster off temporari Ly . 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, en­
sure that the openings are not covered.

-Occasiona l noises when the parking
brake is applied and re leased are norma l
and are not a cause for concern .
- When the vehicle is parked, the parking
brake goes through a se lf-test cycle at
regular intervals. Any assoc iated noises
are norma l.
Parking
Various rules apply to prevent the parked ve­
hicle from rolling away accidentally.
P ar king
,. Stop the vehicle w ith the foot brake.
,. Pull the switch© to apply the parking
brake.
,. Se lect the
P se lector lever position
9 page 112.
,. Turn the eng ine off q _&. .
In addition on incline s and grad es
,. Turn the steering whee l so that your vehicle
wi ll ro ll against the curb in case it should
start to move .
A WARNING
-When you leave your veh icle -even if on­
ly briefly -always take the ignition key
with you. This applies particularly when children remain in the veh icle. Otherw ise
the ch ildren could sta rt t he engine, re­
lease the p arking brake or operate e lec­
trical equipment (e .g. power windows) .
T he re is the risk of an accident.
- When the vehicle is loc ked, no one -par­
t icu la rly not children sho uld remain in
the vehicle . Locked doors make it more
difficult for emergency workers to get in­
to the vehicle -putt ing lives at risk.
Start ing from rest
The starting assist function ensures that the
parking brake is released automatically upon starting.
Stopping and appl ying par kin g brake
,. Pull the switch© to apply the parking
brake.
St arting and automatic ally rel easi ng the

,. When you start to dr ive as usual, the park ­
ing brake is automat ically released and your
veh icle beg ins to move.
When stopping at a traffic signal or stopping in city traffic, the parking brake can be ap­
plied . The vehicle does not have to be held
with the footbrake . The parking brake elimi ­
nates the tendency to creep w ith a dr ive range
engaged. As soo n as you d rive off as usual,
the pa rking brake is re leased automatically
and the vehicle s tarts to move.
Sta rting on slopes
When starting on inclines, the starting assist
prevents the veh icle from u nintent ionally roll­
i ng back. The braking fo rce of the par kin g

Audi braking guard
Description
Applies to vehicles: wit h adapt ive c ru ise control
Fig. 94 Instrument cluster: approach warn ing
Audi brak ing guard uses radar sensors and a
video camera . It is active at speeds above
about 6.2 mph (10 km/h) and also works
within system limits when adaptive cruise control is switched off.
On vehicles with aAdaptive cruise control and
Audi side assist (Audi pre sense plus), system
functions also engage when a co llision is im­
minent
¢page 188.
What can Audi braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud­
denly or if your own veh icle is traveling at a
h igh speed and approaching a vehicle up
ahead that is moving more slowly. Audi brak­
ing guard does not react if it cannot detect
the situation.
The system advises you of various kinds situa­ tions :
- 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 coll is ion. The ind icator
light
I i n the d isplay comes on. Take imme ­
diate action to avoid the coll is ion and in­
crease the distance to the vehicle up ahead. -
The
approach warning is given when a de­
tected vehicle up ahead in your lane is mov­
ing much more slowly that you are or if it
brakes sharp ly. When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharp ly . The indicator
light
I and the symbol in the disp lay will
warn you about the danger
c:> fig. 94 . You
w ill also hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, Aud i braking guard w ill
intervene by braking and the message
braking
guard intervention
w ill appear.
- If a coll is ion is imminent, the system will
first provide an
acute warning by brak ing
sharply .
- If you do not react to the acute warning, Au­
di braking guard will brake w ith increased
force in severa l stages to reduce the speed
in a possible collisio n. On ve hicles w ith
adaptive cruise contro l and Audi side assist
(Audi pre sense plus), the system can brake
with increasing force up to maximum decel­
eration shortly before a sensed collision
¢ page 188.
- If
the Audi braking g uard senses that you
are not braking hard enough when a colli­
sion is imminent, it can increase the braking
force.
Audi braking guard takes the driver's reaction
time into consideration in order to provide
timely warnings. The system reaction time de­ creases automatically in some situations, for
example when it detects accelerator pedal use
or steering input . The Audi braking guard in­
tervent ion stops in certa in situations, for ex­
amp le if you press the accelerato r pedal to
pass the vehicle moving ahead of you in your
lane.
Which functions can be controlled?
You can switch Audi braking guard and the
distance/approach warning on or off in the
M M I c:> page 93, Settings in the MMI.

Adaptive cru ise co ntrol and b rakin g guar d 93
A WARNING ,~
The Audi braking guard is an assist system
and cannot prevent a collis ion by itself.
The driver must always intervene. The driv­ er is always responsible for braking at the
co rrect time.
- Always pay close attention to traffic,
even when the Aud i brak ing guard is
switched on. Be ready to intervene and
be ready to take complete control whe n­
ever necessary. Always keep the safe and
legal distance between your vehicle and
vehicles up ahead.
-Audi braking guard works within limits and wi ll not respond outside the system
limits, for examp le when approaching a
stopped vehicle or stationary obstacle
(end of a traff ic jam or vehicle that has
broken down in traffic).
- Always remember that the radar sensor
for the Audi braking guard works only
within defined detect ion 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 promptly detected or may not be de ­
tected at al l.
- Reflective surfaces includ ing c rash ba rr i­
ers or tunnel en trances may impair the
function of the radar sensor .
(D Tips
Innattention can cause collisions, other ac­
cide nts and serious persona l injuries.
- You can stop the Audi b raking guard in­
te rvention w ith increas ing braking force
by applying the brakes yourse lf or by a c­
ce le rat ing rapidly.

Setting the warning point Early:
With this setting, a warning is provided
before a wheel touches the detected lane
boundary line. The warning depends on the
angle in which the vehicle is approaching the
line. The distance at which the warning is giv­
en increases as the angle becomes sharper. If
you drive toward a boundary line at a very sharp angle, the warning will come just before
a wheel touches the line.
Medium: With this setting, the warning point
is adapted to the course of the road, the lane
width and the speed. You will still be warned
