-The brakes on a vehicle that
has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly, including a blow­
out and sudden deflation,
causing loss of control and a
crash.
-Always make sure that the total load being transported
does not make the vehicle

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 233,
fig. 195.
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
¢ page 233, fig. 195.
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. (1400-750
(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
vehicle. Consult this manual
to determine how this re­ duces the available cargo
and luggage load capacity of
your vehicle.

(c::> page 245, fig. 199) to de­
termine the designated load
rating for a specific tire.
Ti re service life
The service life of tires depends
on a lot of different things in ­
cluding proper installation and
balancing , correct tire pressure
and driving style.

high "wear indicators"

tread. Depending on the make,
there will be six to eight of
them evenly placed around the
tire. Marks on the tire sidewall (for example "TWI" or other
symbols) indicate the positions
of the tread wear indicators.
Worn tires must be replaced.

Tire pressure
Incorrect tire pressure causes
premature wear and can cause
sudden tire blow-out. For this
reason, tire pressure must be
checked at least once a month

_&. WARNING
Sudden tire failure can lead
to loss of control, a crash and serious personal injury!
-Never drive a vehicle when the tread on any tire is worn down to the wear indica­
tors.
-
-Worn tires are a safety haz­ ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and brake fluid away from tires.
-Tires age even if they are not being used and can fail
suddenly, especially at high
speeds. Tires that are more
than 6 years old can only be used in an emergency and
then with special care and at lower speeds.
-Never mount used tires on your vehicle if you are not sure of their "previous histo­ry." Old used tires may have
been damaged even though
the damage cannot be seen

We recommend that all work
on tires and wheels be per­
formed by an authorized Audi dealer. They are familiar with
recommended p rocedures and
have the necessary special too ls
and spare parts as well as the proper facilities for disposing of
the old ti res.
Autho rized Audi dealers have
the necessary information
about technical requirements
for installing or changing tires
and rims .
Replacing tires and wheels
Tires sho uld be replaced at
least in pairs and not individu ­
ally (for example both front
tires or both rear tires togeth­
er).
B e sure to read and heed the in ­
formation to the tire pressure
monitoring system
c::> page 255.
Always buy replacement radial
tires that have the same specifi­
cations as the tires approved
for your vehicle by Audi. Re­
placement tires must always
have the same load rating spec­
ification as the original equip­
ment or approved optional tires

Your vehicle is normally factory
equipped with tires, which pos-
sess excellent driving character-
istics and give your Audi opti-
mum driving comfort.
l) For tires with a maximum speed ca­
pability over 149 mph (240 km/h) ,
tire manufacturers sometimes use
the letters "ZR."
U.S. DOT Tire Identification
Number (TIN) and tire
manufacture date
This is the tire's "serial num-
ber". It begins with the letters
"DOT" and indicates that the
tire meets all federal stand- ards. The next two numbers or letters indicate the plant where
it was manufactured, and the
last four numbers represent the
week and year of manufacture. For example, the numbers
2214 mean the tire was pro-
duced in the 22nd week of
2014. The other numbers are
marketing codes that may or
may not be used by the tire
manufacturer. This information
is used to contact consumers if
a tire defect requires a recall.

"AO" or "RO" have been special- ly matched with your Audi. We
