ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades => page 249.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans
mits this information to the tire pressure monitoring system *. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system * on your vehicle.
If the sensors are to be installed on different rims , the seal, washer ,
and valve cap for each sensor must be replaced.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system* will not work properly.
In this case, the tire pressure moni
toring system * would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho
rized Audi dealer to replace lost valve stem caps.
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni
toring system*, and is not recommended (cord material information
in molded on the tire sidewall) .
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehicle. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring sys tem* , or some component o f the
tire pressure monitoring system* may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• 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 that can lead to sudden
tire failure and loss of vehicle control. .,_

[ i) Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after
wards=>
page 256.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni
toring system*=>
page 257. •
Ap plies to vehicles: w ith tir e pressure monitor in g system
Storing tire pressures
Correct storage of specified pressure is the basic require
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni
toring system
In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load
conditions, please see chapter
=> page 238. .,_

& WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=> page
284, fig. 178 and
=> page 284, fig. 179.
- 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,
causing serious personal injury.
0 Note
• Be aware 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 points.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist .
- Before driving over a workshop hoist, ensure that there is
sufficient clearance between the hoist and low parts of the
vehicle. •

Weights
Gross Vehicle Weight Rating
The Gross Vehicle Weight Rating (GVWR), and the Gross Axle Weight
Rating (GAWR) for front and rear are listed on a sticker on the left
door jamb.
Controls and equip ment Safety first Vehicle operation
The
Gross Vehicle Weight Rating includes the weight of the basic
vehicle plus full fuel tank, oil and coolant, plus maximum load,
which includes passenger weight (150 lbs/68 kg per designated
seating position) and luggage weight.
Gross Axle Weight Rating
The Gross Axle Weight Rating is the maximum load that can be
applied at each axle of the vehicle~&.
Vehicle capacity weight
The vehicle capacity weight (max. load) is listed either on the
driver's side 8 -pillar or inside the fuel filler flap.
Roof weight
The maximum permissible roof weight is 165 lb (75 kg). The roof
weight is made up of the weight of the roof rack system and the
weight of the object being transported
~ page 80, "Loading the
roof rack".
& WARNING
• The actual Gross Axle Weight Rating at the front and rear axles
should not exceed the permissible weights, and their combination
must not exceed the Gross Vehicle Weight Rating.
• Exceeding permissible weight ratings can result in vehicle
damage, accidents and personal injury.
0 Note
• The vehicle capacity weight figures apply when the load is
distributed evenly in the vehicle (passengers and luggage). When
transporting a heavy load in the luggage compartment, carry the
load as near to the rear axle as possible so that the vehicle's
handling is not impaired.
• Do not exceed the maximum permissible axle loads or the
maximum gross vehicle weight. Always remember that the vehicle's .,_
