Wear
Brake pad wear depends largely on the way the
vehicle is driven and on operating conditions.
This is especially true if you are driving frequently in the city and on curves or with a sporty driving
style.
Operating noise
Noises may occur when braking depending on the
speed, braking force and outside conditions such
as temperature and humidity.
Wet conditions or road salt
In certain situations, for example after driving
through water, in heavy rain or after washing
your car, the braking effect may be reduced due
to moisture or ice on the brake rotors and brake
pads. The brakes must be "dried" first with a few
careful brake applications.
At higher speeds and with the windshield wipers
turned on, the brake pads press against the brake
rotors for a short amount of time. This action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather.
The braking effect can also be reduced if you are
driving on salted roads and you do not apply the brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied.
Corrosion
Leaving the vehicle parked for long periods of
time, low mileage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads.
If you usually avoid heavy braking or if there is
corrosion present, occasional heavy braking at high speeds is recommended to clean the brake
rotors and
pads¢ ,&..
Brake system malfunction
If you notice that the brake pedal travel has sud­
denly increased, then a brake circuit in the dual­
circuit brake system may have malfunctioned. Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately to have the
Intelligent Technology
problem corrected. On the way there, drive with
reduced speed and keep in mind that you will
need a longer distance to stop and you will need
to press the brake pedal harder.
Low brake fluid level
When the brake fluid level is low, malfunctions in
the brake system may occur. The brake fluid level
is electronically monitored.
Brake booster
The brake booster amplifies the pressure you ap­
ply to the brake pedal.
& WARNING
= -
- Only apply the brakes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­
danger other road users. This increases the
risk of an accident.
- Never let the vehicle roll while the engine is
stopped because this increases the risk of an
accident.
- Never place objects in the driver's footwell.
An object could end up in the area around
the pedals and prevent you from using
them. You would not be able to use the ped­
als if sudden driving or braking maneuvers
were needed, which increases the risk of an
accident.
- Only use floor mats that do not obstruct the
area around the pedals and that can be se­
curely fastened in the footwells.
- To reduce the risk of injury, do not place
your foot under the brake pedal.
@ Note
- Never let the brakes "rub" by pressing the
pedal lightly when braking is not actually
necessary. This causes the brakes to over­
heat and increases braking distance and
causes wear.
- Before driving downhill a long distance on a
steep hill, decrease your speed and select a
lower gear. This makes use of the engine
braking effect and relieves the brakes. If
you need to brake additionally, brake in in- tervals and not continuously.

Glossary of tire and loading
terminology
Accessory weight
means the combined weight (in
excess of those standard items
which may be replaced) of auto­ matic transmission, power steer­
ing , power brakes , power win­
dows , power seats, radio, and
heater, to the extent that these
items are available as factory-in­
stalled equipment (whether in­
stalled or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indicate a
low sidewall for improved steer­
ing 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.
328
Cord
means the strands forming the
plies in the tire.
Cold tire inflation pressure
means the t ire pressure recom­
mended by the vehicle manufac­
turer for a tire of a designated
size that has not been driven for
more than a couple of miles (kilo ­
meters) at low speeds in the
three hour period before the tire pressure is measured or adjusted.
Curb weight
means the weight of a motor ve­
hicle w ith standard equipment in­
cluding the maximum capacity of
fuel, oil, and coolant, ai r condi­
tioning and additional weight of
optional equipment.
E x tra load ti re
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­
sponding standard tire. Extra load
tires may be identified as "X L",
"
l" "EXTRA LOAD" or "RF" on X I I
the sidewall. .,.

Wheels
Production options we igh t
means the combined weight of
those installed regular production
options weighing over 5 lbs.
(2.3 kg) in excess of those stand­
ard items which they replace, not previously considered in curb
weight or accessory weight, in­
cluding heavy duty brakes, ride levelers, roof rack, heavy duty
battery, and special trim.
Radial pl y tir e
means a pneumatic tire in which
the ply cords that extend to the beads are laid at substantially
90 degrees to the centerline of
the tread.
R ecomm ended in flation
pressure
see¢ page 328 , Cold tire infla­
tion pressure.
R einforced tire
means a tire designed to operate
at higher loads and at higher in­
flation pressures than the corre­
sponding standard tire . Rein ­
forced tires may be identified as
"XL" "xl" "EXTRA LOAD" or "RF" , , ,
on the sidewall.
330
Rim
means a metal support for a tire
or a tire and tube assembly upon
which the tire beads are seated.
Rim diam eter
means nominal diameter of the
bead seat . If you change your
wheel size, you will have to pur ­
chase new tires to match the new rim diameter .
Rim size designation
means rim diameter and width.
Rim width
means nomina l distance between
r im
flanges .
Sidewall
means that portion of a tire be­
tween the tread and bead .
Speed rating (letter code )
means the speed at which a tire is
designed to be driven for extend­
ed periods of time. The ratings range from 93 mph (150 km/h)
to
186 mph (298 km/h) ¢ table
on page 326 .
You may not find
this information on all tires be­
cause it is not required by law .

vehicle's Gross Veh ic le Weig ht
R ati ng
("GVWR").
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 150 lbs . (68 kg) for each passen­
ger at a designated seating posi ­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load .
The
Gro ss Ax le W eight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles .
T he fact that there is an upper
limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited . The more pas­
sengers in the vehicle or passen -
338
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as luggage .
The Gross Vehicle Weight Rating and the Gross Axle Weight Rat ing
are listed on the safety compli­
ance sticker labe l located on the
driver's side B-pillar.
1.8. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance .
-Tires on a vehicle that has been overloaded can fail sud ­
denly, including a blowout and
sudden deflation, causing loss
of contro l and a crash.
-Always make sure that the to­ tal load being transported

wash operator to reduce the risk of acci­
dents.
- To reduce the risk of cuts, protect yourself
from sharp metal components when wash­ ing the underbody or the inside of the wheel
housings.
- After washing the vehicle, the braking effect may be delayed due to moisture on the
brake rotors or ice in the winter . This in­
creases the risk of an accident. The brakes
must be dried first with a few careful brake
applications.
@ Note
- If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Power folding exterior mirrors* must only
be folded in and out using the power folding
function.
- To reduce the risk of damage to the rims
and tires, compare the width between the
wheels on your vehicle with the distance be­
tween the guide rails in the car wash.
- To reduce the risk of damage, compare the
height and width of your vehicle with the
Care and cleaning
height and width of the inside of the car
wash .
- T o reduce the risk of paint damage, do not
wash the vehicle in direct sunlight .
- To reduce the risk of damage to the surface,
do not use insect removing sponges, kitchen
sponges or similar items .
- Matte finish painted vehicle components:
- To reduce the risk of damage to the sur-
face, do not use polishing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash the vehicle in facilities specially de­
signed for that purpose. This will reduce the
risk of dirty water contaminated with oil from
entering the sewer system.
