t he funct ion of the tire pressure monitor-
ing system*.
- Always inflate tires to the recommended
and correct tire pressure before driving
off.
- Driving with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire fail ure
and loss of control.
- If the t ire pressure is too low or too high,
the tires will wea r prematurely and the
vehicle will not hand le we ll.
- If the t i re is not flat and you do not have
to change a w heel immed iate ly, dr ive at
reduced speed to the nearest serv ice sta-
t ion to check the tire pressure and add
air as requi red.
{Q) Note
Driving without va lve stem caps ca n cause
damage to the t ire valves. To prevent this,
always ma ke sure t hat facto ry installed
va lve stem caps on all wheels a re secu re ly

Tires and vehicle load limits
There are limits to the amo unt of load or
weight that any vehicle and any tir e can carry .
A veh icle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle contro l,
but ca n a lso damage import a nt parts of the
ve hicle and can lead to sudden tire failure, in-
cluding a blowout and sudden deflation that
can cause the ve hicle 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 everyth ing in and on t he vehicle . These
Tire s an d wheel s 253
load limits are technically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes t he weight of the basic
vehicle, a ll factory installed accessories, a full
tan k of fuel, oil, coo lant and other fluids plus
max imum load. The max imum load includes
the number of passengers t hat the vehicle is
intended to carry ("seat ing capac ity") with an
ass umed we ight of 150 lbs (68 kg) fo r each
passenger at a designated seating posi t ion
and the tota l weight of a ny luggage in the ve-
hicle. If you t ow a tra ile r, the we igh t of t he
tra iler hitch an d the t ongue we igh t of t he
loaded tra iler mus t be included as part of the
vehicle load .
The
Gross Axle Weight Rating ("GAWR") is
the max imum load th at can be a ppl ied at each
of the veh icle's two axles .
The Gross Vehicle Weight Rat ing and t he
Gross Axle Weig ht Rati ng are listed on the
safety comp lian ce sti cker label locate d on t he
driver's side B-pillar. Your Audi has
5 seat ing
pos itions , 2 in the front and 3 in the rea r for
total seating capacity of 5. Vehicles with pow-
er individual rear seats* have 4 seating posi-
tions, 2 in the front and 2 in the rear for total
seat ing capac ity of 4. Each seating position
has a safety belt
c::> page 143, Safety belts.
The fact that there is an upper limit to you r
vehicle's Gross Vehicle Weight Rating means
that the to t al weight of whatever is being car-
ried in the vehicle (includ ing t he weight of a
tra iler hitch a nd the tongue we ight of t he
loaded tra ile r) is lim ited. The more passen-
gers in t he vehicle or passe ngers who are
heavier th a n t he sta ndard we ights assumed
mean t ha t less we igh t can be carried as lug-
gage.
The ti re pressure label on your Aud i also list s
the max imum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry. For the location of the
