-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment. You
could burn yourself. Let the engine cool off
first until you can no longer see or hear steam or coolant escap ing .
Q) Note
-Mounting additional lights or accessories in
front of the air inlets reduces the cooling ef­
fect of the radiator. At h igh outside temper­
atures or h igh engine load, the engine cou ld
ove rheat.
- The front spoiler has been designed to prop­
erly distribute the cooling air when the veh i­
cle is moving.
If the spoiler is damaged, this
could red uce the cooling effect and the en­
gine could then overheat . Ask your author ­
ized Audi dealer for assistance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM).
You shou ld shift to the next lowest gear when
the speed is below 1500 RPM. The beginning of
the red zone in the tachometer indicates the maximum permissib le engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before reaching the red zone, you should shift into the
next h igher gear, choose the Dor S selector lever
position, or remove your foot from the accelera ­
tor pedal.
CD Note
The tachometer needle© c::> page 10, fig. 3
should only be in the red zone br iefly: other­
w ise, this increases the risk of e ngine dam-
age. The location where the red zo ne begins
varies depend ing on the eng ine.
@, For the sake of the environment
Upshifting early helps you to save fuel and re­
duce operating noise.

-Objects fal ling from the roof of a vehicle can
cause a crash and personal injury.
- Only mount the roof rack on the designated
locations on the roof
c:> fig. 67.
-The roof rack system must be installed ex­
act ly according to the instructions provided .
- When driving with a roo f rack system,
changes to the center of gravity and wind
resistance can change the vehicle handling
and lead to a collision. Always adapt your
dr iv ing and your speed to the current condi­
t ions.
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Audi for your vehicle . The same applies to
damage result ing from incorrect roof rack
i nstallation.
-Always check the roof rack mount ings and
hardware before each t rip and dur ing a tr ip
to make sure everyt hing is securely tight­
ened.
If necessary, ret igh ten the mo unt ings
and c hec k the en tire system from time to
time.
- After mounting a roof rack system, or when
you transport objects on the roof of your ve ­
hicle, the height of the vehicle is naturally
increased . Be careful when driving under
l ow bridges or in parking garages for exam­
ple. This could cause damage to the load
and even the vehicle itself.
- Make s ure the open rear lid and the sun­
roof* do not come into contact with the roof
rack.
Loading the roof rack
Always distribute loads evenly. Make sure any­
thing on the roof rack is securely tied down.
~ Always distribute the loads on the roof rack
evenly .
~ Always attach items to the roof rack securely
before you drive off.
The maximum perm iss ible roof weight is
220 lb
( 100 kg ).
The roof weight is the total of the
Seat s and sto rage
weight o f the roof rack, the attachments and the
cargo you are carrying. You must a lso not exceed
the max imum load weight for the roof rack you
are using.
When using a roo f rack system which has a lower
load carrying capacity, you must not use up the
total max imum permissible load carry ing capac i­
ty specified above. Instead, you should load the
roof rack system only to the maximum capacity
specified by the manufacturer of the roof rack
system .
A WARNING
= -Weak, damaged or imprope r straps used to
secure items to the roof rac k can fail d uring
hard brak ing o r in a co llision and cause seri ­
ous persona l injury.
- Make sure the roof r ack is installed exactly
as specified above
c:> page 62.
- Always use suitable mounting straps fo r se­
cur ing items to the roof rac k to he lp prevent
items from shifting o r flying forward .
- Items on the roof rack mus t always be se ­
curely mounted.
- The use of a roof rack can negative ly affect
the w ay a vehicle hand les. Cargo tha t is
large, heavy, b ulk y, long or flat wi ll have a
grea ter negat ive infl uence on the vehicle's
aerodynamics, center of gravity and overa ll
handling. Always drive slowly, avoid sudden
braking and maneuvers when transporting
cargo on the roof of your vehicle.
- Never exceed the max imum permissib le
load carrying capacity of the roof of your ve­
h icle, the permiss ible axle weights and the
perm iss ible total we ight of your vehicle
c:> page 2 70, Weights .
@ For the sake of the environment
As a result of the increased wind res istance
created by a roof rack, your vehicle is using
fuel unnecessarily . So remove the roof rack
after using it .

Warm and cold Climate control system
Description
App lies to vehicles: with three-zone climate control or four ­
zone a utomat ic climate contro l
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 sun­
roof* are closed .
If the temperature inside the
parked vehicle becomes very warm, opening the
window briefly will 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.
Condensat ion 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.
T he 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
Three-zone climate control: The blower setting
and air distribution are stored automatically and
assigned to the remote contro l key that is in use.
Four-zone automatic climate control: Th e cli­
mate control settings are automatically stored
and assigned to the remote contro l key that is in
use.
Warm and cold
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 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 vent ilation system. The washer so lu­
tion may freeze on the w indshield and re­
duce visibility.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a qualified dealership.
- Repa irs to the Aud i air cond itioner require
special technical knowledge and special
tools. Contact an authorized Audi dea ler for
assistance.
@ For the sake of the environment
By reduc ing 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 availab le
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.

Fuel and Refueling
These fuels contain substances that can se ­
verely damage the fue l system and the en­
gine if the engine is started .
Refueling
Fuel filler neck
The fuel fill er neck is located on the right rear
side panel beh ind the fuel fil ler flap.
If the power locking system should fail , you can
still open the flap manually - for detailed instruc­
tions see ¢
page 212.
You can find the fuel tank capacity of your vehicle
i n
¢ page 271 .
The label on the inside of the fuel filler flap tells
you the correc t fuel for you r vehicle . For more in­
formation about fuel specifications , see
¢ page 208 .
Your vehicle fuel t ank has an onboard refuelling
vapor recovery system . This fea tu re helps to pre­
vent fuel vapors from escaping from the tank and
polluting the environment while you refuel your
vehicle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully.
8_ WARNING
Under normal operating conditions, never car­
ry additiona l fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
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 blower, etc.,
be
very careful and always observe local and
state laws regard ing the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86).
(D Note
Never drive your vehicle until the fuel tank is
completely empty. T he irregular supply of
fue l can cause m isfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Refuelling
Fig. 178 Righ t re ar v ehicl e side : O penin g the fuel fill er flap
Fig. 179 Fuel fille r flap w it h att ach ed fuel c ap
When act iv a ting the central locking, the fuel fill­
er flap is automatically unlocked or locked. Re ­
fuel the veh icle with the ignition switched
off.
Taking the fuel cap off
.. Press the left s ide of the fuel filler flap to open
i t ¢
fig. 178 -arrow-.
.. Unscrew fuel filler cap counter-clockwise and
hang it on the fuel filler flap~
fig. 179.
.. Check the label on the inside of the fuel filler
flap to determine if the vehicle must be fueled
w ith gasoline or diesel fuel.
Refuelling procedure
.. Insert the fuel nozzle from the gasoline pump
into the fuel filler neck as far as it will go .
.. Select a med ium refuelling rate so that the
nozz le switches off automatica lly when the
tank is full.
Putting the fuel cap back on
.. After filling your tank, twist the fuel filler cap
clockw ise as far as it will go .
.. Close the fuel filler flap.

To avoid fuel spilling or evaporating from the fuel
tank always close fuel filler cap properly and
completely. An improperly closed fuel filler cap
may also cause the MIL lamp
c> page 28 to come
on.
A WARNING
Improper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause se­
vere burns and other injuries.
- Failure to shut the engine off while refuel­
ing and/or to insert the pump nozzle fully
into the fuel filler neck could cause fuel to
spray out of filler neck or to overflow. Fuel
spray and overflowing fuel can cause a fire.
- Never use a cellular telephone while refuel­
ing. The electromagnetic radiation can
cause sparks that can ignite fuel vapors and
cause a fire.
-
-Never get back into your vehicle while refu­
eling.
If in exceptional circumstances you
must get back in your vehicle while refuel­
ing, make certain that you close the door
and touch metal to discharge static electric­
ity before touching the filler 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 refueling 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 container, 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 exam­
ple, in the luggage compartment, or on
the trunk). Static electricity can build up while filling and can ignite fuel vapors
causing a fire.
- Always place a portable fuel container on
the ground before filling.
Fuel and Refueling
- Always keep the filler nozzle completely
inside the portable container before and
during filling.
- If filling a portable container made of
metal, the filler nozzle must always be in
contact with the container. This will help prevent static electricity from discharging
and cause a fire.
- Never spill fuel inside the vehicle or lug­
gage compartment. Fuel vapors are highly
flammable .
- Always observe local and state/provincial
laws regarding the use, storage and trans­
portation of fuel containers.
- Make certain the fuel container meets in­ dustry standards (ANSI/ ASTM F852 -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
switches 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 fuel to overflow when it becomes
warm and pollute the environment.
(D Tips
-Running your engine while refuelling may
cause vapors to escape or even cause fuel to
spill out of the tank. This would then shut
off the fuel nozzle before the tank is full.
- Do not refuel your vehicle with the ignition
switched on. The fuel gauge may otherwise
not indicate the correct fuel level after refu­
elling.
- Diesel vehicles* are equipped with a diesel
misfueling protector.
It allows the vehicle
to be fueled only with a diesel fuel pump nozzle. A worn or damaged nozzle or a noz­
zle that is too small may not be able to open
the diesel misfueling protector. If this is the .,..
