Following each intentional change in specified pressures , tire pres­
sures must be resaved .
Af ter the pressures are saved, the tire pressure monitoring system
measures the current tire pressures and saves them as the new
specified pressures .
[ i] Tips
• The tire pressure is shown on the tire pressure label. On USA
vehic les, the tire pressure label is located on the driver's side 8-
pillar. On Canada vehicles, the tire pressure labe l is located either on
the driver's side 8 -pillar or inside the fuel filler flap . The tire pressure
label lists the recommended cold tire inflation pressures for the
vehicle at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured. For recommended tire
pressures for normal load cond itions, please see chapter
~ page 297.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures. But the driver stil l has the responsibility for
mainta ining the correct tire pressure. •

the roof r ock is tied down securely.
Always distribute the loads on the roof rack evenly .
Controls and equip­
ment
Always secure items to the roo f rack.
The maximum perm issible roof weight is 16 5 lb (75 kg ). The roof
weight is made up of the weight of the roof rack system and the
weight of the object being transported :=:>
page 341.
When using a roof rack system which has a lower load carrying capacity, you must not use the tota l maximum permissible load
carrying capacity. If this is the case, you may load the roof rack
system only to the maximum capacity specified by the manufac ­
turer of the roof rack system .

Intelligent technology
Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders" .
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were insta lled in a vehicle for the express purpose of
retrieving data after an accident or crash event without the owner's
consent.
Although your vehicle is not equipped with an EDR, it is equipped
with a number of electronic control modules for various vehicle
systems such as, for example, engine function, emission control, as
we ll
as for the airbags and safety belts.
These electronic control modules also record vehicle-related data
during normal vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic control modules is limited
to data (no sound is recorded) and only a small amount of data is
actually recorded over a very limited period of time and stored when
a system fault or other condition is sensed by a control unit. Some
of the data then stored may relate to vehic le speed, d irection,
braking as well as restraint system use and performance in the
event of a crash or other condition . Stored data can only be read and
down loaded with special equipment. •
Electronic Stabilization Program (ESP)
General information
The ESP improves the vehicle stability.
(X) CD
Fig. 199 Center

sw itch
ESP is designed to he lp you maintain vehic le control in situations
where the car approaches the limits of "grip", especial ly when
acce lerating and cornering. ESP reduces the risk of skidding and
improves stability under al l road conditions.
The system operates across the entire speed range in combination
with the ABS system . If the Anti-Lock Brake System (ABS) malfunc ­
t ions, the ESP will a lso shu t down.
How the system works
The Anti-Lock Brake System (ABS), Electronic Differential Lock (EDU
and the Anti -Slip Regu lation System (ASR) are integrated in the e lec ­
tronic stabilization program . In addition to the data provided by
these functions, the ESP control unit requires additional measure ­
ment data provided by high performance sensors. The rotational

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

&, 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.
•

prescribed number of miles or perform in a certain way . It simply
gives ti re buyers additiona l info rmation to combine with other
considerations, such as price, brand loyalty and dea ler recommen -dations

and t he last four numbers represent the wee k and year of manufac ­
ture. For example,
DOT ... 2205 ...
means t hat the tire was produced in the 22t h week of 2005. The

M aintaini ng proper t ire pressure is one of the most im po rta nt
thi ngs you ca n do t o help avo id sud den t ire fa ilu re. Underi nflated
tires are a major cause of sudden tire failure. Keeping tires at the
ri ght pressure is also importa nt for safe and r espo nsive ve hicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speed s, and then especially when heavily loaded even within the

T ire pressure generally refe rs to the amou nt of air in a t ire that it
needs it to do its job and safely carry the combined load of the entire
veh ic le and i ts c ontents. Tire p ressu re is measu red in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI) . Tir e p res su re is based in part on th e vehic le's design and
load lim it - the greatest amount of weight that the veh ic le can carry
safely and the tire size . The proper tire pressure is frequently
re ferred to as the "recommended cold t ire infla tion pressure." A ir in
the tires expands when the tire heats up because of internal friction
when it fl exe s i n us e. The tir e press ure is high er w he n th e t ire has

The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
The tire pressure label located either on driver's side 8-pillar or
inside the fuel filler flap on your Audi lists the recommended cold
tire inflation pressures for the vehicle at its maximum capacity
weight and tires that were on your vehicle at the time it was manu­
fac tured .
If you wish to improve comfort when operating the vehicle at
normal load (up to 3 occupants), you can adjust tire pressures to
those specified for normal vehicle load. Before operating the vehicle at maximum load, you must increase the tire pressures to those
specified for maximum vehicle load
~ & .
If your vehicle is equipped with a tire pressure monitoring system*,
bear in mind that the system can only monitor the tire pressures you have stored
. The system does not recognize the load condition of
your vehicle.
The effectiveness of the tire pressure monitoring system will be
impaired if you store normal load pressures but then operate the
vehicle at its maximum
load~& .
See the illustration~ page 297, fig . 217 for the location of the label
either on driver's side 8-pillar or inside the fuel filler flap (color of
the actual label and exact location on the vehicle will vary slightly).
Note that the following table is accurate at the time of going to
press and is subject to change . In the event of discrepancies, the tire
pressure label (e ither on driver's side 8 -pillar or inside the fuel filler
flap) always takes precedence.
The table below lists the recommended cold tire inflation pressures

LJ}. WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident , serious personal injury, and even death .
• Carrying more weight than your vehicle was designed to carry
will prevent the vehi cle from handling properly and in crease the
risk of the loss of vehicle control.
• The brakes on a vehi cle that has been overloaded may not be
able to stop the vehicle within a safe distance .
• Tires on a veh icle that has been overloaded can fail suddenly ,
including a blowout and sudden deflation , causing loss of control
and a cra sh .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehi cle 's Gro ss Vehicle Weight Rating .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport so that you can make sure that
your vehicle will not be overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE COMBINED
WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS " on your vehicle's placard (tire infla­
tion pressure
label) => page 297, fig. 217.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo ­
grams or
"XXX" pounds shown on the
sticker=> page 297 , fig. 217.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, if the
" XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400 -750 (5
X 150) = 650 lbs.) ..

5. Determine the combined weight of luggage and cargo being loaded on the
vehicle. That weight may not safely
exceed the available cargo and luggage
load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidewall(::::>
page 305,
fig. 221) to determine the designated
load rating for a specific tire.•
