The correct tire pressure for the spare wheel i s
l ocated on a label on the driver's side 8-pilla r.
Because technical changes may be made to
vehicle equ ipment during the model year, al
ways compare the tire size designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle. Ma ke sure that the tire
size information on the veh icle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be l ongs to someone else or you bought the vehi
cle with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on making sure that
l oad limits are not exceeded. Vehicle load in
cludes everybody and everything in and on the
vehicle. These load limits are technically refer red to as the vehicle's Gross Vehicle We ight
Rating ("GVWR") . The Gross Axle Weight Rat
i ng ("GAWR") is the maximum load that can
be appl ied at each of the veh icle's two axles.
The G ross Vehicle Weight Rating and the Gross Axle Weig
ht Rating are listed on the
safety compl iance sticker label located on the
drive r's side 8-pillar . The tire pressure labe l on
your A udi lists the maxim um combined
weight of all of the occ upants and luggage or
other cargo that t he vehicle can carry. Fo r the
location of the tire pressure label ¢
fig. 251.
A WARNING
Overloading a vehicle can cause loss of ve
h icle control, a crash or other accident, se
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in
crease the risk of a loss of vehicle con
trol.
- The brakes on a vehicle that has been overloaded may not be able to stop the
veh icle w ith in a safe distance.
- T ires on a vehicle that has been overload
ed can fail suddenly caus ing loss of con-
trol and a crash. ..,.
