Remember, your safety and that of your pas-
sengers also depends on making sure that
load limits are not exceeded. Vehicle load in-
cludes everybody and everything in and on the
vehicle. These load limits are technieally 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 applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labellocated on the
driver's side B-pillar. The tire pressure label on
your Audi lists the maximum combined

wall.
The correct tire pressure for the spore wheel is
located on a label on the driver's side B-pillar.
Because technical changes may be made ta
vehicle equipment during the model year, al-
ways compare the tire size designation on the
tire pressure label on your vehicle with the
tires on your vehicle. Make sure that the tire
size information on the vehicle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be-
longs to someone else or you bought the vehi-
ele with different ri ms/tires or you bought the
Vehicle as a previously owned 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.
The tire pressure label is located on the driv-
er's side B-pillar. The tire pressure labellists
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.
Bear in mind that the tire pressure monitoring
system can only monitor the tire pressures
you have stored. The system does not recog-
nize the load condition of your vehicle.
The effectiveness of the tire pressure monitor-
ing system will be impaired ifyou store nor-
malload pressures but then operate the vehi-
cle at its maximum load q,&.
See the illustration

fig. 150 for the location
of the label on driver's side B-pillar (color of
the actuallabel and exact location on the ve-
hicle will vary slightly).

If you wish to improve comfort when operat-
ing the vehicle at normalload (up to 2 occu-
pants), you can adjust tire pressures to those
specified for normal vehicle load. Before op-
erating the vehicle at maximum load, you
must increase the tire pressures to those
specified for maximunrvehicle load q,&.

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 interna-
tional measuring unit and in pounds per
square inch (PSI). Tire pressure is based in
part on the vehicle's design and load limit-
the greatest amount ofweight that the vehi-
cle can carry safely and the tire size. The prop-
er tire pressure is frequently referred to as the
"recommended cold tire inflation pressure."
Air in the tires expands when the tire heats up
because of internal friction when it flexes in
use. The tire pressure is higher when the tire
has 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 pres-
sure" 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. Keep-
ing tires at the right pressure is also impor-
tant for safe and responsive vehicle handling,
traction, braking and load carrying. Tire pres-
sures are particularly important when the
vehicle is being driven at higher speeds, and
then especially when heavily loaded even
within the permissible load-carrying capaci-
ties approved for your vehicle.
