_& WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death .
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a loss of vehicle con­
tro l.
- The brakes on a veh icle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly causi ng loss of con­
tro l and a crash.
- Always make sure that the total load be­
ing transported -including the we ight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
A WARNING
-Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­ dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
-
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­
lar .
The recommended tire pressures are on the
tire pressure label and in the table
¢ page 234, Cold tire inflation pressure .This
means that the pressure m ust be checked and
adjusted when the tire has not been driven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when it is "co ld ."
It is the inflation pressure in a "cold" tire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendations ¢
page 234. The
tires would then be underinflated and could
fail suddenly .
The tire pressure label on your Audi lists the
recommended cold tire inflation pressures at
maximum capacity for the new, original
equipmen t tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the labe l
¢page 234, fig. 174.
Most tires lose air naturally over t ime. They
can also lose some air if yo u drive over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial tires
used today are underinflated just by looking
at them.
T here fore, be sure to check ti re pressures at
least once a month and a lways before going
on a long trip . Make sur e to take the number
of peop le and the amount of luggage into ac­
count when adjust ing tire pressure for a trip -
even one that you would not consider to be
"long ." See ¢
page 238, Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflat ion pres­
sures. Check all of the tires and be sure not to
forget the spare tire.
If the pressure in any tire
i s too h igh when the tire is "cold", let air out
of the tire slowly with the edge of the tire
gauge and keep check ing the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold .,..

238 Tires and wheels
-If the tire pressure is too low or too high,
the tires will wear prematurely and the
vehicle will not handle well.
- If the tire is not flat and you do not have
to change a wheel immediately, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without valve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that facto ry installed
valve stem caps on all wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also increase the
fuel consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any tire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle control,
but can a lso damage important parts of the
vehicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the vehicle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle . These
load limits are techn ically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories , a full
tank of fuel , oi l, coolant and other fluids plus
maximum load. The maximum load includes
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 tota l weight of any luggage in the ve- hide.
If you tow a trai ler, the weight of the
trailer hitch and the tongue weight of the loaded trailer must be included as part of the
vehicle load.
T he
Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles .
T he Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pillar.Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Each seating posi­
tion has a seat belt <=>
page 136, Safety belts .
The fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the to tal weight of wha tever is being car­
ried in the vehicle ( including the weight of a
tra iler hitch and the tongue weight of the
loaded trailer) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mean that less we ight can be carried as lug­
gage.
T he tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
label <=>page234 , fig.174.
A WARNING
-Overloading a vehicle can cause loss of ve-
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your vehicle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle with in a safe distance .
- Tires on a vehicle that has been overload­
ed can fail suddenly, incl uding a blowout
and sudden deflation, causing loss of
con trol and a crash .

-Always make sure that the total load be­
ing transported - including the weight of
a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehi­
cle heav ier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port 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 OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation pressure label)
¢ page 234,
fig. 174.
2. Determine the combined
weight of the driver and pas­ sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­ sengers from
"XXX" kilo­
grams or
"XXX" pounds
Tires and wheels 239
shown on the sticker
¢ page 234, fig. 174.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five
150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is
650 lbs. (1400-7 50
(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 trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle.
.,. Check the tire sidewall
(¢ page 241, fig. 178) to de­
termine the designated load rating for a specific tire.
