Driving without valve stem caps can cause damage to the tire
valves. To prevent this, a lways make sure that factory instal led valve
stem caps on a ll whee ls are securely mounted on the va lve .
W Fo r the sake of the env ironm ent
Underinflated tires wil l a lso increase the fuel consumption. •
Tires and vehicle load limits
There are lim its to t he amount of load or weight that any ve hicle and
any tire can carry . A vehicle that is overload ed wil l not hand le well
and is more difficu lt to stop. Overload ing can not only lead to loss
of vehic le control , but can a lso damage important parts of the
vehic le and ca n lead to sudden t ire fa ilure, inc luding a blowout a nd
sudden deflation that can cause the vehic le to crash.
Your safety and that of your passengers also depends on making
sure that load l imits are not exceeded. Vehicle load includes every­
body and everything in and on the vehic le. These load limits are
technica lly referred to as the vehicle's
Gross Ve hicle We ig ht R ating
("GVWR").
The "GVWR" includes t he weight of the bas ic ve hicle, al l factory
insta lled accessories, a full tank of fuel , oil , coolant and other fluids
p lus maximum load . The maximum load i ncludes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
the vehicle . If you tow a trailer, the weight of the trailer h itch and the
tongue we ight of the loaded trai ler must be included as part of the
vehic le load.
The
Gros s Axle We ight Rating ("GAWR") is the maximum load t hat
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 comp liance s ticker label loca ted either on
the driver's side B-pillar or on the inside of the fuel fil ler flap . Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Eac h seating position has a safety be lt
~ page 209, "Safety be lts".
The fact that there is an upper limit to your veh icle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the veh ic le ( including t he we ight of a trai ler hitch and the
tongue weight of the loaded trai ler) is limited . The more passengers
in the vehicle or passengers who are heavier than the standa rd
we ights assumed mean that less weight can be carried as luggage .
The tire pressure labe l on your Audi also lists the maximum
combined we ight of a ll of the occupants and luggage or other cargo
that th e vehicle can carry. For the location of the lab el

Vehicle care

-Tires and wheels Determining correct load limit
Use the example below to calculate the
total weight of the passengers and
luggage or other things that you plan to
transport 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 OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label) => page 328, fig. 272.
2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo­
grams or
"XXX" pounds shown on the
sticker=> page 328, fig. 272. 4. The resulting figure equals the available
amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity 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 trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the avail­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidewall
( => page 336,
fig. 276) to determine the designated
load rating for a specific tire. •

may or may not be used by the tire manufacturer . This information
is used to contact consumers if a tire defect requires a recall.
T ire p ly co mpos ition and mate ria ls used
The number of plies indicates the number of layers of rubber -coated
fabric in the tire . In genera l, the greater the number of p lies, the
more weight a tire can support. Tire manufacturers also must ind i­
cate the materials in the tire, which include steel, ny lon, polyester,
and others.

T he wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire , and then trans ­
m its this information to the tire pressure mon itoring system. If you
are going to replace the whee l rims on your vehicle, make sure the
n ew rims also have t hese sensors. The sensors mus t be compa tible
with the tire pressure monitoring system on your vehicle .
I f you instal l rims, which do not have the sensors, or have sensors
whic h are not compatible, then the t ire pressure monitoring system
wi ll not work properly. In this case, the tire pressure monitoring
system would not be ab le to mon itor the tire pressure or warn you
if it is necessary . .,_

Lifting with vehicle jack
Refer to => page 354.
& WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor ja ck lift points illustrated
=> page 369 , fig. 304 and
=> fig . 305.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen , for
example , when heavy components such as the engine block or
transmission are removed .
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of gravity. Otherwise , the vehicle might tilt or slip off the hoist,
c ausing serious personal injury .
0 Note
• Be awar e of the following points before lifting the vehicle :
-The vehicle should never be lifted or jacked up from under­
neath the engine oil pan , the transmission housing , the front or
rear axle or the body side members . This could lead to serious
damage .
-To avoid damage to the underbody or chassis frame , a rubber
pad must be inserted between the floor jack and the lift point s.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the
hoid . ~

• The ve hicle capacity weight figures apply when the load is
distributed evenly in the vehic le (passengers and luggage) . When
tra nsporting a heavy load in the luggage compartment, carry the
load as near to the rear ax le as possible so that the vehic le's

handling wil l be affected by the extra load. Therefore, adjust your
speed accord ingly .
