The washer fluid container is marked with the symbol its cap.
- Before you check anything in the engine compartment,
always read and heed all WARNINGS~ & in "Working
in the engine compartment" on
page 307.
- Lift the filler cap tongue to add washer fluid. You can fill
the container to the top.
- Press the cap back onto the filler neck after filling the
container .
You can find the reservoir capacity in the table in=> page 378.
Use winterized windshield washer solvent during the cold season
even though the vehicle is equipped with heated washer jets. It
helps to keep your windshield clean and prevents the fluid from
freezing in the winter.
Follow the directions on the container for the correct amount to be
used.

& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their
"previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage.
•
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted.
Curb weight
means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire design to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire. Extra load tires
may be identified as
"XL", "xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating
("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces.
Gross Vehicle Weight Rating
( " GVWR")
means the maximum total loaded weight of the vehicle.

0 Not e
Driving without valve stem caps can cause damage to the tire
valves. To prevent this, a lways make sure that factory instal led valve
stem caps on a ll whee ls are securely mounted on the va lve .
W Fo r the sake of the env ironm ent
Underinflated tires wil l a lso increase the fuel consumption. •
Tires and vehicle load limits
There are lim its to t he amount of load or weight that any ve hicle and
any tire can carry . A vehicle that is overload ed wil l not hand le well
and is more difficu lt to stop. Overload ing can not only lead to loss
of vehic le control , but can a lso damage important parts of the
vehic le and ca n lead to sudden t ire fa ilure, inc luding a blowout a nd
sudden deflation that can cause the vehic le to crash.
Your safety and that of your passengers also depends on making
sure that load l imits are not exceeded. Vehicle load includes every­
body and everything in and on the vehic le. These load limits are
technica lly referred to as the vehicle's
Gross Ve hicle We ig ht R ating
("GVWR").
The "GVWR" includes t he weight of the bas ic ve hicle, al l factory
insta lled accessories, a full tank of fuel , oil , coolant and other fluids
p lus maximum load . The maximum load i ncludes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
the vehicle . If you tow a trailer, the weight of the trailer h itch and the
tongue we ight of the loaded trai ler must be included as part of the
vehic le load.
The
Gros s Axle We ight Rating ("GAWR") is the maximum load t hat
can be applied at each of the vehicle's two axles. The Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety comp liance s ticker label loca ted either on
the driver's side B-pillar or on the inside of the fuel fil ler flap . Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Eac h seating position has a safety be lt
~ page 209, "Safety be lts".
The fact that there is an upper limit to your veh icle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the veh ic le ( including t he we ight of a trai ler hitch and the
tongue weight of the loaded trai ler) is limited . The more passengers
in the vehicle or passengers who are heavier than the standa rd
we ights assumed mean that less weight can be carried as luggage .
The tire pressure labe l on your Audi also lists the maximum
combined we ight of a ll of the occupants and luggage or other cargo
that th e vehicle can carry. For the location of the lab el
