2009 AUDI S4 CABRIOLET load capacity

Following each intentional change in specified pressures, tire pres­
sures must be resaved .
After 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 label is located either on
the driver's side 8 -pi llar or insid e 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 conditions , please see chapter
=> page 271.
• The tire pressure monitoring system he lps the driver to keep an
eye on tire pressures . But the driver st ill has t he responsibi lity for
maintaining the correct tire pressure .•

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDRl,
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 retrieva l 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 examp le, engine function, emission control, as
we ll as for the airbags and safety belts.
T hese electronic control modules also record vehic le-rela ted da ta
during norma l ve hicle operation for diagnost ic 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 we ll 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)

co nsol e w ith ESP
sw itch
ESP is designed to he lp you maintain vehic le control in situa tions
where the car approaches the limits of "grip", especially when acce lerating and cornering . ESP reduces the risk of skidding and
improves stability under all road conditions .
The syst em opera tes across the en tire speed range in combination
with the ABS system. If the Anti-Lock Brake System (ABS) malfunc ­
tions, the ESP wil l a lso shut down .
How th e sys te m work s
The Anti-Lock Brake System (ABS) , E lectronic Differential Lock (EDU
and the Anti -Sl ip Regu lation System (ASR) are integrated in the e lec­
tronic stabi li z ation program. In addition to the data provided by
these functions, the ESP control unit requires additional measure­ ment data provided by high performance sensors . T he rotational
speed of the vehic le about its ver tica l axis, t he late ral acce leration
acting on the vehic le, the brake pressure and the steering ang le are
a ll measured .

Tire pressure generally refers to the amount of air in a tire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals (kPa), the internationa l measuring unit and in pounds per square
inch (PSI!. Tire pressure is based in part on the vehic le's design and

warmed up than when it is "cold." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.
Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying.
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle .
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.
On USA vehicles, the tire pressure label is located on the driver's
side B-pillar . On Canada vehicles, the tire pressure label is located
either on the driver's side B-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 tires that were
on your vehicle at the time it was manufactured.
If you wish to improve comfort when operating the vehicle at
normal load (up to 2 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 271, fig. 207 for the location of the label
either on driver's side B-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 (either on driver's side B-pillar or inside the fuel filler
flap) always takes precedence .
The table below lists the recommended cold tire inflation pressures
for the Audi model covered by your Owner's Literature at the

tive models as original equipment, or as a factory option.

and is more difficult to stop. Overloading can not only lead to loss
of vehic le contro l, but can also damage important parts of the
vehic le and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash .
Your safety and that of your passengers also depends on making sure that load limits are not exceeded . Vehicle load includes every ­
body and everything in and on the veh icle . These load lim its are
technically referred to as the vehicle's
G ross Vehicle Weight R ating
("GVWR").
The "GVWR" includes the weight of the basic vehic le, all factory
installed accessories, a ful l tank of fuel, oil, coolant and other fluids
p lus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed we ight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
t he vehicle. If you tow a trai ler, the weight of the trailer hitch and the
tongue weight of the loaded trai ler must be included as part of the
vehic le load .
T he
G ros s Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehicle's two axles .
The Gross Vehicle Weight Rat ing and the Gross Axle Weight Rating
are listed on the safety compliance sticker labe l located either on
the d river's side B -pillar o r on t he inside of the f ue l fi ller flap. Yo ur
Audi has 4 seating positions, 2 in the front and 2 in the rear for total
seating capaci ty of 4. Each seating posi tion has a safety belt
=>
page 159, "Safety be lts" .
T he fact that there is an upper limit to your vehicle's Gross Vehicle
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 weigh t of the loaded trailer) is lim ite d. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure labe l on your Audi also lists the maximum
combined weight of a ll of the occupants and luggage or othe r cargo that the vehicle can carry
. For the location of the label=>
page 271,
f ig. 207 .
& WARNING
Overloading a vehicle can cau se lo ss of vehicle control , a cra sh or
other a ccident , seriou s personal injury , and even de ath .
• Carrying more weight th an your vehi cle w as designed to ca rry
will prevent the vehi cle from handling properly and in cre ase the
ri sk of the lo ss of vehicle control.
• The brakes on a veh icle th at ha s been overloaded ma y not be
able to stop the vehicle within a safe distance .
• Tire s on a vehicle that has been overloaded can fail suddenly,
i ncluding a blowout and sudden defla tion , cau sin g los s of control
and a crash .
• Alwa ys make sure that the tot al l oad be ing tran sported -
including the weight of a trai ler hit ch and the tongue weight of a
loaded trailer -does not m ake the vehicle heavie r than the

Determining correct load limit
U se th e exa mple below to calculat e the
total weight of the passengers and luggage or other things that you plan to
tran sport so that you can make sure that
your vehi cle will n ot be ov erlo ad ed.
~

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 271, fig. 207.
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 271, fig. 207.
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 I bs.)
Tires and wheels 1111111
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 279,
fig. 211) to determine the designated
load rating for a specific tire. •
