damage to the load and even the vehicle
itself.
- Make sure that the open rear lid and the
sunroof do not come into contact with
objects on the roof.
Loading the roof rack
Always distribute loads evenly. J\llake sure
anything on the roof rock is securely tied
down.
.. Always distribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack secure-
l y before you drive off.
The maximum permissible roof weight is
200 lb (90 kg). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carrying. You must also not exceed the maximum load weight for the
roof rack you are using .
When using a roof rack system which has a
lower load carrying capacity, you must not use
up the total maximum permissible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the
maximum capacity specified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a collision and
cause serious personal injury.
- Make sure the roof rack is installed exact­
ly as specified above
~ page 67.
- Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shifting or flying for­
ward.
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negatively af­
fect the way a vehicle handles. Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
.
the vehicle's aerodynamics, center of
gravity and overall handling. Always
drive slowly, avoid sudden braking and maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
vehicle, the permissible axle weights and
the permissible total weight of your vehi­
cle~
page 2 75, Weights.
(D Note
Make sure that the opened rear lid does
not come in contact with the cargo on the
roof.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
using fuel unnecessarily. So remove the
roof rack after using it.

76 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 there is a build-up of
heat inside the vehicle, ventilation can help to
speed up the cooling 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.
Condensat ion 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 s uch
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.
If you drive your vehicle in an area with h igh
a ir po llution, the fi lter may need to be
changed more frequent ly than specified in
your Aud i Wa rranty
& Ma intenance booklet. If
in doubt, ask your authorized Audi Service Ad ­
visor for advice .
Key coded settings
The climate control settings are automat 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 shie 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 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, en­
sure that the openings are not covered.

216 Fuel supply and filling your fuel tank
-Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline
¢ page 214.
@ Tips
I t may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain
substances that can cause depos its to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
b rands include additives to keep eng ine and
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
f u els, b uilt-up carbon deposits can rob your
engine of peak performance.
CJ) Note
-Damage or malfunct ion due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Wa rranty.
- Do not add aftermarket fuel addit ive
products to your fuel tank .
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap. If the power
locking system should fai l, you
can still open the flap manua lly -for detailed
instructions see
¢page 218.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 277 .
T he label on the inside of the fuel filler flap
te lls you the correct fuel for your veh icle. For
more information about fuel specifications,
see ¢
page 214.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fue l vapors from escaping from the
tank and polluting the environment while you
refuel your vehicle. In order to fi ll the tank
proper ly while protecting the environment,
please fo llow this refueling procedure careful­
ly.
A WARNING "'--
Under normal operating cond itions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other conta iners used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision . If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al ­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tai ner meets industry standards (ANSI/
ASTM F852 -86).
(D Note
Never drive your veh icle until the fuel tank
i s completely empty. The irregular supply
of fuel can cause misfiring. Gasoline could
enter the exhaust system and damage the
catalytic converter.

_& WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can cause a fire .
- Never use a cellular telephone while re­
fueling. The electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain that you close
the door and touch metal to discharge static electricity before touching the fill­
er nozzle again. Static electricity can
cause sparks that can ignite fuel vapors
released during refueling .
- Never smoke or have an open flame any­
where in or near your vehicle when refu­
eling or filling a portable fuel container .
- For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle . The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, under exceptional circumstances, you must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling.

218 Fuel supply and filling your fuel tank
-Always keep the filler nozzle complete­
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal , the filler no zzle must always be
in contact with the container. Th is will
help prevent static electricity from dis ­
charging and cause a fire .
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable .
-Always observe local and state/provin ­
cial laws regarding the use, storage
and transportation of fuel containers.
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F 852-86).
(D Note
If any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint .
@ For the sake of the environment
As soon as the correctly operated nozzle
sw itches off automatically for the first
time, the tank is full . Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fue l to
overflow when it becomes warm and pol ­
lute the environment.
@ Tips
-Running yo ur engine while refuelling
may cause vapors to escape or even
cause fue l to spill out of the tank . This
would then shut off the fuel nozzle be­
fore the tank is full.
- Do not refuel your vehicle with the igni­
tion turned on. The fuel gauge may oth­
erwise not indicate the correct fuel level
after refuelling .
- The fuel filler flap of your vehicle is not locked when you lock the vehicle from
the inside .
Unlocking the fuel filler flap by hand
You can open the fuel filler flap by hand if the
power locking system should fail.
