vehicle with different rims/tires or you bought
the vehicle as a previously owned vehicle.
Remembe r, your safety and that of yo ur pas­
sengers also depends on mak ing s ure that
l oad limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
veh icle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing (''GAWR") is the maximum load that can
be appl ied at each of the veh icle's two axles .
The Gross Vehicle Weight Rating and the
Gross Axle We igh t Rating a re listed on the
safety compliance s ticker labe l located on the
d river's side 8-p illa r. T he tire pressure label on
your Audi lists the maximum combined weight of all of the occupants and luggage or
other cargo that the vehicle can carry. For the
locat ion of the tire pressure label¢
fig. 208.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a cras h or other accident, se­
rious personal inju ry, and even death .
-Carry ing more weight than your vehicle
was designed to carry will prevent the
vehicle from handling p roperly and in­
cr ease the ris k of a loss of veh icle con­
t ro l.
- T he bra kes on a veh icle that has been
overloaded may no t be able to stop t he
vehicle within a sa fe distance.
- T ires on a vehicle that has been ove rload­
ed can fail suddenly causing loss of con­
t ro l and a c rash.
- Always make sure that the tota l load be­
ing t ransporte d -including the we igh t of
a tra iler hi tc h and the tongue weight o f a
loaded trailer -does not make the vehi ­
cle heavier t han the vehicle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­ flation can lead to a serious or fata l acci­
dent .
-
Tire s an d wheel s 251
-Inco rrect tire pressures and/or unde rin­
flation ca use increased tire wear and can
affect the handling of the vehicle .
- Incorrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowout and sudden de­
f lation, caus ing loss of veh icle 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 labe l and in the table
¢ page 249 , Cold tire inflation pressure. This
means that the pressure m ust be checked and
adjusted when the t ire has not been dr iven fo r
more than a couple of mile s (kilometers) a t
l ow speeds d uring the previous th ree ho urs.
Air in the tires expands when the tire hea ts up
as a result of interna l friction as it flexes in
u se . T he t ire pressure is higher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "co ld" t ire that
counts . Therefore, you should never let air out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat ions ¢
page 249 . The
tires would then be underinflated and co uld
fail suddenly .
The tire pressure label on your Audi lists the recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your ve hicle at
the time it was manufactured. For the loca ­
tion of the label¢
page 249, fig . 208 .
Most tires lose air naturally over t ime . They
can a lso lose some air if you drive over a pot­
ho le or hit a curb while park ing.
It is usually
not possible to see whether the rad ial tires
used today are under inflated just by loo kin g
at them.
T herefo re, be sure to check t ire pressu res at
least once a month and a lways before going
o n a long t rip. Ma ke su re to ta ke t he number ..,.

254 Tires and wheels
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 weight than your vehicle
was designed to carry will prevent the
vehicle 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
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control 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 heavier 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 ve­
hicle's placard (tire inflation pressure label)
¢ page 249,
fig. 208.
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
shown on the sticker
c> page 249, fig. 208.
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 SO
(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 .,.

Changing a wheel
Before changing a wheel
Observe the following precautions for your
own and your passenger's safety when chang ­
ing a wheel.
• After you experience a t ire failure, pull the
car well away from moving traffic and try to
reach
leve l ground before you stop c:::> ,&.
• All passengers should le av e t he ca r and
move to a safe location (for ins tance, behind
t he guardra il)
c:::> ,& .
• Engage the parki ng br ake to prevent your
vehicle from rolling unintentionally
c:::> ,& .
• Move sele ctor lever to po sit ion P c:::> ,&. .
• If you are towing a trailer, unhitch the trailer

c:::> page 267,
c:::> page 268 .
& WARNING
You o r you r passengers could be i njured
while changing a wheel if you do not fo l­
low these safety precaut ions:
-I f you have a flat tire, move a safe d is­
tance off the road. Turn off the engine,
turn the eme rgency flashers on and use
other warning devices to a lert other mo­
torists .
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always f ully set the parking brake
and b lock the wheel d iagonally opposite
the wheel be ing changed. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"
(Par k) will
not prevent the vehicle from
mov ing .
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jac k.
