Audi dealer .
• A tight tether or other str ap on a rearward-fac ing child restr aint
attached to the front pas senger seat can put too much pressure
on the weight-sensing mat in the seat and reg ister more weight
than i s actually on the seat. The heavier weight registered can
make the system work as though an adult were on the seat and
deploy the Advanced Airbag when it must be suppressed causing
s erious or even fatal injury to the child .
• If, in exceptional circumstance s, you mu st in stall a forward ­
fac ing child restra int on the front passenger seat , always move the
seat into its rearmost position in the seat 's fore and aft ad just ­
ment range , as far away from the airbag a s possible . The backrest
must be adjusted to an upright position . Make sure that the
PASSENGER AIR BAG OFF light comes on and stay s on all the time
whenever the ignition is switched on .
& WARNING
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after taking the steps
described above, make sure the adult is properly seated and
restrained at one of the rear seating positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .
[ i ] Tips
If the weight -sensing mat in the front passenger seat detects an

Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
your Au di. In sta ll in g, re moving, ser vic in g or re pair in g a part in an
area of the vehicle can damage a part of an a irbag system and
pre ven t that system fro m wo rki ng p rope rly in a co llision .
There are some important things you have to know to make sure
that the effectiveness of the system will not be impai red an d that
d iscarded components do not cause inju ry or po llute t he e nv iron ­
ment .
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly:
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way .
• Never attach any obje cts su ch as cup holders or telephone
mountings to the surfaces covering the airbag units.
• For cleaning the horn pad or instrument panel, use only a soft ,
dry cloth or one moi stened with plain water . Solvents or cleaners
c ould damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust , or change any parts of the airbag system.
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
c ellular telephones and CB radios , etc .I must be performed by a

& WARNING
Overloading a vehi cle can cause loss of vehicle control , a crash or
other accident, serious personal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance .
• Tires on a vehicle that has been overloaded c an fail suddenly
causing loss of control and a crash .
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
s erious o r fatal a ccident .

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
When should I check the tir e pressure?
The correct ti re pressure is especially i mpor tant a t high speeds . The
pressure should therefore be checked at least o nce a month and
a lways before star tin g a j ourn ey.
When should I adjust the tire pressures?
Adjust the tire pres sure to the loa d you are ca rrying. After changing
a wheel
or replacing whee ls you have to adjust the tire pressures on
a ll whee ls. In addition, y ou must the n ini tia lize the new tire pres ­
sures in the tire pressu re monitoring system*:::::,
page 253.
& WARNING
Incorrect tire pressures and /or underinflation can lead sudden tire
failure, loss of control , collision, serious personal injury or even
death .
• When the warning symbol appears in the instrument
cluster , stop and in spect the tire s.
• Incorrect tire pressure and /or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability.
• Incorre ct t ire pressures and /or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pre ssure s for all
tires on the vehicle . The appli cable pressure values are located on
a sticker on the driver' s side B -pillar.
• Onl y when all tires on the vehicle are filled to the correct pres­
sure , the tire pre ssure monitoring system* can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it is essential that the driver observe
the spe cified tire pressure values for the tires and the correct pres­
sures for the function of the tire pre ssure monitoring sy stem *.
• Always inflate tires to the recommended and correct tire pres­
sure before driving off.
& WARNING (continued )
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation, sudden tire failure and lo ss
of control .
• Excessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high , the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately, drive at reduced speed to the nearest servi ce station
to che ck the tire pres sure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always ma ke sure that fac tor y in st alled va lve
stem caps on all wh eels are securely mounted on the valv e.
'£> For the sake of the environment
Underinflated tires w ill also increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehic le and
any tire can ca rry. A vehicle that is overloaded wil l not handle wel l
and is more difficu lt to stop . Overloading can not on ly lead to loss
of vehic le contro l, but can also damage important parts of the
ve hicle a nd can l ead to sudden t ire fa ilure, i nclud ing a b lowout an d
sudden deflation that can cause the vehicle to crash .

& WARNING (continued)
• Do not adjust tire pressure when tire temperature is excessive.
This could lead to serious tire damage and even cause the tire to
burst, with the additional danger of an accident.
Driving with under -inflated tires reduces fuel efficiency and tire
tread life.
[ i] Tips
• Each tire should be checked monthly when the temperature of
the tires is about the same as ambient air temperature and set to the
recommended inflation pressure as specified on the tire pressure
label =>
page 238.
• The factory supplied spare wheel is equipped with a sensor for
the tire pressure monitoring system *. As long as the spare wheel is
not mounted, the tire pressure of this tire will not be monitored.
• The tire pressure monitoring system * helps the driver to keep an
eye on tire pressures. But the driver still has the responsibility for
maintaining the correct tire pressure.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves should not be
exchanged . The valve core, nut, valve sealing and seal washer
(replacement kit) needs to be replaced. If necessary, the valve and
the wheel electronics have to be replaced.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system*.
Otherwise the system will register a malfunction and a fault
message will be displayed. For more information, contact your Audi
dealer. •
Adjust the tire pressure and store the pressure in the tire pres­
sure monitoring system* to the load you are carrying.

[ 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. .,_
