Cooler
Introduction
Applies to vehicles: wi th coo ler
Please clean the cooler before using it for the
first time ¢
table on page 216.
You can only switch on the cooler if
- the temperature in the luggage compart­
ment is below 131 °F (55 °C). The cooler
switches off automatically if the tempera­
ture in the luggage compartment exceeds
131 °F (55 °C). Once the temperature falls
below 131 °F (55 °C) again, the cooler
switches on again automatically.
- the battery is adequately charged. The cool­
er switches off automatically if the vehicle
battery voltage falls below a minimum lev­
el. This prevents the battery from discharg­ ing. The cooler switches back on again auto­
matically when the battery voltage increases
again (e .g. after starting the engine).
The cooler cools to 42.8 °F
(+ 6 °C) and the
freezer cools to 21.2 °F (-6 °C) in optimum
cooling conditions. The cooling performance
is affected by the temperature in the luggage
compartment . The temperature inside the
cooler will be higher if the luggage compart-
ment is hot. .,.

_& WARNING
To avoid putting the occupants at any risk,
please observe the following safety rules:
- The maximum capacity is 2.5 kg (5.5
lbs.).
- Never over load the cooler. This could
cause injury in the event of a co llision or
sudden braking.
- The coo ler lid must always be kept closed
while you are driving. Make sure the re­
taining catch is securely engaged. The
contents of the cooler could be thrown
forward into the passenger compart­
ment in the event of a collision or under
sudden braking - risk of in jury!
- Inflammable liquids, gas canisters, etc.
must not be stored in the cooler - risk of
exp losion! This also includes any prod­
ucts that might emit volatile or inflam­
mab le gases.
- Liquids will freeze at temperatures at or
below
32 °F (0 °C) and may cause glass
bottles to burst!
(D Note
- The ventilation openings for the cooler
are located on the back panel trim in the
l uggage compartment and
must be kept
clear at all times.
- If the cooler is not functioning properly,
switch it off to prevent further damage.
Have it checked by a qualified workshop .

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.
