2015 AUDI A8 warning

78 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 pol lutant filter removes pollutants such
as dust and pollen 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 fi lter 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 funct ion of the heat ing
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 know ledge 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.

ment and improper seating position can
cause serious personal injury . -
Adjust the steering wheel col umn only
when the vehicle is not mov ing to pre­
vent loss of vehicle control.
- Adj ust the driver's seat or steering whee l
so that there is a minimum of 10 inches
(25 cm) between your chest and the
steer ing wheel
Q page 134, fig . 153 . If
you cannot mainta in th is m inimum dis­
tance, the airbag system cannot p rotect
you properly.
- If physical limitations prevent you from sitt ing 10 inches (25 cm) or more from
the steering wheel, check wit h your au­
thorized A udi dealer to see if adaptive
equipment is available .

Starting off with a trailer
To prevent rolling back unintentionally on an
incline, do the following:
11-Keep the switch© pulled and depress the
accelerator. The parking brake stays applied
and prevents the vehicle from rolling back­
ward .
11-You can release the switch<®> once you are
su re that you a re develop ing enough for­
ward momentum at the wheels as you de­
press the accelerator.
D epending on the weight of the r ig (vehicle
and tra ile r) and the severi ty of the incl ine, you
may roll backwards as you start. Yo u can pre­
vent rolling backwards by holding the parking brake switch<®) p ulled out and acce lerating -
just as you would when starting on a hill with
a conventional hand brake.
Emergency braking
In the event that the conventional brake sys­
tem fails or locks.
11-In an emergency, pull the switch(®) and
contin ue to p ull it to slow your vehicle down
with the parking brake.
11-As soon as you release the switch (®) or ac-
ce lerate, the braking process stops.
If you pull the switch<®> and hold it above a
speed of about 5 mph (8 km/h), the emergen­
cy braking function is initiated. The vehicle is
braked at all four wheels by activating the hy­
draulic brake system. Th e brake performance

In order not to activate the emergency brak­
ing by m istake, an audible warning tone (buz­
ze r) sou nds when the switch C®> is pulled. As
soon as the switch(®) is released, or the accel­
e rator pedal is dep ressed, emergency b ra ki ng
stops.
_& WARNING
Emergency braking should only be used i n
an emergency, when the normal foot brake
has failed or the brake pedal is obstructed .
On the ro ad 87
Using the parking b rake to pe rform emer­
gency brak ing will slow your vehicle down
as if you had made a full brake application.
The laws of physics cannot be suspended
even with ESC and i ts associated compo­
nents (ABS, ASR, EDL). In corners and
when road o r weathe r cond itions are bad,
a full brake appl ication can ca use the vehi­
cle to sk id or the re ar end to break away -
risking an acciden t.
