Bear in mind that the tire pressure monitoring
system* can only monitor the tire pressures
you have stored. The system does not recog
ni ze the load cond it ion of your vehicle.
The effectiveness of the tire pressure monitor
ing system* will be impaired if you store nor
mal load pressures but then operate the vehi
cle at its maximum load
c;, & .
See the illustration c;, fig. 196 for the location
of the label on driver's side B-pillar (co lor of
the actua l labe l and exact location on the ve
hicle will vary slightly).

254 Tire s and wheel s
-The use of incorrect tire pressure values
can lead t o acci dents or other damage .
T herefore it is essential that t he driv er
o bserve the specified tire pressure values
for the ti res and the correct pressu res for
the f unct ion of the tire pressure mon itor
ing system*.
- Always inflate tires to the recommended
and co rrect tire pressure befo re d riving
off.
- Driv ing with under inflated ti res bend
more, lett ing them get too hot resu lting
in t read separation, sudden t ire fa il u re
and loss o f control.
- E xcess ive speed and/ove rloading can
c ause heat bui ld-up, sudden t ire fail ure
and loss o f control.
- If the t ire p ress ure is too low or too high,
the tires w ill wear prematu rely and the
vehicle will not hand le we ll.
- If the t ire is no t flat and you do no t have
to change a wheel immed iate ly, drive at
reduced speed to the nearest service sta
t ion to check t he tire pressure and add
air as required.
(D Note
Dr iving w ithou t va lve s tem 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 secure ly
mounted on the valve.
@ For the sake of the environment
Unde rinflated tires will a lso increase the
fue l cons umption.
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire ca n car ry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop . Over load ing
can no t on ly lead to loss of veh icle contro l,
b ut can also damage impor tan t par ts of the
vehi cle and can lead to s udden tire failure, in
cluding a blowout and sudden deflation that
can cause the veh icle to crash. Your safety and that of your passengers also
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everything in and on the veh icle. These
load lim its are technically referred to as the
vehicle's
Gro ss Vehicle Weight Rating
("GVWR").
The "GVWR" includes t he weight of the basic
vehicle, a ll factory installed accessories, a full
tank of fuel, o il, coolant and other fluids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
i ntended to car ry ("seat ing capac ity") with an
ass umed we igh t of 150 lbs (68 kg) for e ach
passenge r at a designated seating posi tion
and the total weight of any luggage in the ve
hicle . If you tow a trai ler, the weight of the
trai ler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
The
Gros s Axle Weight R ating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two axles.
The Gross Vehicle Weight Rat ing and the
Gross Ax le Weight Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar . Your Audi has 4 seat ing
pos itions, 2 in the front and 2 in the rear for
total seating capacity of 4 . In some vehicles
the re a re 5 seating pos it ions, 2 in the front
and 3 in the rear for tota l seating capacity of
5. Each seat ing position has a safety belt
¢ page 140, Safety belts .
T he fact that there is a n upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
t h at the total weig ht of whatever is bei ng car
ried in the vehicle ( in cl udi ng the weight of a
trai ler hi tch and the tongue weight of the
l oaded trai le r) is limited . 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 a ll of the
occupants and luggage or other cargo that .,..
When the malfunction indicator is illuminat
ed, the system may not be able to detect or
signal low tire pressure as intended. TPMS
malfunctions may occur for a variety of rea
sons, including the installation of replace ment or alternate tires or wheels on the vehi
cle that prevent the TPMS from function ing
properly . Always check the TPMS malfunction
tellta le after replacing one or more tires or
wheels on your vehicle to ensure that the re
placement or alternate tires and wheels allow
the TPMS to continue to function properly.
Tire pressure indicator appears
Applies to vehicles: with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.

Using the ABS sensors, the tire pressure moni
toring system compares the tire tread circum
ference and vibration characteristics of the in
dividual tires . If the pressure decreases in one
or more tires , th is is indicated in the instru

and avoid any hard steering or braking
maneuvers. Stop as soon as possib le and .,.
26 6 T ire s and whee ls
check the tires and their pressures. In
flate the tire pressure to the proper pres
sure as indicated on the vehicle's tire
pressure label
c> page 250. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also is likely to impair the vehicle's handling and stop
ping ability.
- T he driver is responsible for ma inta ining
the correct tire pressures. You must check the t ire pressures regular ly .
- Under certain cond itions (such as a spor
ty driving style, winter condit ions or un
paved roads), the pressure monitor indi
cator may be de layed .
- Ask your author ized Audi dealer if r un
flat tires may be used on your vehicle .
Your vehicle regist ration becomes invalid
if yo u use these tires when not permit
ted. Damage to your veh icle or accidents
cou ld also result.
- The tire pressure monitoring system
stops working when there is an ESC/ABS
malfunction .
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your Audi was developed using tires with
the "AO" or "RO" identif ication on the
tire sidewall
