Air vents
You can open and close the center and rear air
vents using the thumbwhee ls. The levers ad ­
just the direction of the airflow from the
vents.
In vehicles with a 3-zone deluxe automatic cli­
mate control system*, you can adjust the air
temperature in the rear by turning the thumb­
wheel toward the red side to make it warmer
or toward the b lue s ide to make it cooler.
A WARNING
-- Do not use the recirculation for extended
periods of time . The windows could fog
up since no fresh air can enter the vehi­
cle . If the windows fog up, press the air
recir culation butto n aga in imm ediately
to switch off the air recirculation func­
tion or se lect defrost.
- I ndivid uals w ith reduced sensitivity to
pa in or temperature could develop burns
when using the seat heating function . To
red uce the risk of injury, these individu­
als shou ld not use seat heating.
(D Note
To avoid damage to the heating elements
in the seats, do not kneel on the seats or
place heavy loads on a small area of the
seat.

216 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­ ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
-Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with the engine running: -
First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~&, .
.&_ WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition, certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.

-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have bee n dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology
Accessory weight
means the comb ined weight (in excess of
those standard items wh ich may be rep laced)
of automati c transmission, power steering,
power br akes, power wi ndows, power sea ts,
radio, and heater, to the ex tent that these
items are avai lab le as factory -installed equip­
ment (whether installed or not).
Aspect ratio
means the ratio of the height to the w idt h of
the tire in percent. Numbers of 55 or lower in ­
d icate a low sidewall fo r improved s teer ing re­
sponse and better overall handling on dry
pavement.
Bead
means the pa rt of the t ire that is made of
s teel wires, wrapped or re inforced by ply cor ds
and that is shaped to fit the r im.
Bead separation
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire.
Cold t ir e infl ation pr essure
means the tire pressure recommended by the
vehicle manufacturer for a t ire of a designated
size that has not been dr iven for more than a
couple of miles (kilometers) at low speeds in
the three hour period before the tire pressure i s measu red or adjusted.
Tire s an d wheel s 231
-If you notice un usua l vibration or if the
veh icle pulls to one side when driv ing, a l­
ways stop as soon as it is safe to do so and check the wheels and tires for dam­

standard equipment includ ing t he maximum
capa city of fuel, o il, and coolant, ai r cond i­
tion ing a nd addi tional weig ht o f optiona l
equipment .
Extra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
respondi ng s tanda rd tire. Extra load tires may
be identified as "X L", "xl", "EXTRA LOAD", o r
"R F" on the sidewall .
Gross Axle Weight Rating ( "GAWR ")
mea ns the load-carrying capacity of a single
axle system, measured at the tire-ground in­
te rfaces.
Gross Vehicle Weight Rating ( "GVWR ")
means the maximum total loaded we ight of
t h e ve hicle.
Groo ve
means the space between two adjacent tread
ribs.
Load rating (code )
means the maximum load tha t a t ire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be­
ca use it is not required by law.
Maximum load rating
me ans the load r ating for a tire at the maxi­
mum pe rm issi ble inflat ion pressure for that
ti re .
