& WARN ING (continued )
• Always make sure that the side airbag can inflate without inter­
fe rence :
- Never install seat covers or replacement upholstery over the
front seatback s that have not been spe cifically approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate .
- Damage to the original seat covers or to the seam
in the area
of the side airbag module must always be repaired immedi ­
ately by an authorized Audi dealer .
• The airbag system can be activated only once. After an airbag
ha s inflated , it must be replaced by an authorized Audi de aler or
qualified technician who has the technical information , training
and special equipment necessary .
• The airbag system can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenance booklet under AIRBAG REPLACEMENT
RECORD .
• For safety reasons in severe accidents , the alternator and
starter are separated from the vehicle battery with a pyrotechn ic
circuit interrupter.
-Work on the pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
- If the vehi cle or the circuit inte rrupter is scrapped , all appli ­
cable safety precautions must be followed. •
Other things that can affect Advanced Airbag
performance
Changing the vehic le 's suspens ion system can change the way that
th e Adva nced Air bag Syste m performs in a c rash. Fo r example,
using tire -ri m co mbinations not approved by Audi, lowering the
veh ic le, c hang in g the st if f ness o f th e suspe nsio n, incl uding th e
spr ings, suspension struts, shock absorbers etc. can change the
f o rces t hat a re m easured by the a irba g se nsors and se nt to the elec ­
tronic control unit. Some suspension changes can, for example,
i ncrease the fo rce level s meas ure d by the senso rs and make the
a irbag system dep loy in crashes in which it wou ld not d ep loy if the
changes ha d no t been made . O th er ki nds of changes may red uce
th e force levels measured by the sensors and preve nt the airbag
fro m deploying w hen it sh ould.
Th e senso rs in th e sa fety belt buc kle fo r the dr iver a nd fro nt
passenger seat te ll the e lectronic control modu le if the safety belt is
l a tc h ed or not. If th e sa fe ty belt is being use d, th e front airbag wi ll
deploy at a slightly higher rate of vehic le dece leration than if the
sa fe ty be lt is n ot b ein g use d. Th ere fore, i n a partic ula r co llisi on, i t is
possible that an airbag wi ll not deploy at a seating position where
th e sa fe ty be lt is bei ng us ed bu t wi ll infl ate at the position w here the
safety be lt is not being used. It is important that nothi ng interfere
with the safety belt buc kles so that the sensors can send the co rrect
i nformatio n about safety belt use to t he electronic control unit.
& WARNING
Changing the vehicle's suspension including use of unapproved
tire -rim combinations can change Advanced Airbag performance
and increase the risk of serious personal injury in a crash.
• Never install suspension components that do not have the
same pe rformance characteristics as the components originally
installed on your vehicle.
• Never use tire -rim combinations that have not been approved
by Audi. ..

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 148 Tire pressure
label: located
on
driver 's side B-pillar
Tire pressure generally refers to the amount of air in a tir e that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents. Tire pressure is measured in kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure." Air in
the tires expands when the tire heats up because of internal friction
when it flexes in use. The tire pressure is higher when the tire has
warmed up than when it is "cold ." It is the inflation pressure in a
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure" recommendations .
The tires would then be underinflated and could fail suddenly.

Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure . Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying .
Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load -carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting .
Th e tire pressure label located on driver's side 8 -pillar on your Audi
lists the recommended cold tire inflation pressures for the vehicle
at its maximum capacity weight and tires that were on your vehicle
•
at the time it was manufactured . .,

Because technica l changes may be made to vehicle equip ment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. Th is is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making su re tha t load limits a re not exceeded . Vehi cle loa d
inc ludes everybody and everything in and on the vehicle. These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVW R"). The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two
ax les. The Gross Vehicle We ight Rat ing and the Gross Ax le Weig ht

& 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 __ _
•
& WARNING (continued)
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
on driver's side 8-pillar.
The recommended tire pressures are on the tire pressure label and
in the table=>
page 238, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal friction as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold."
It is the inflation pressure in a "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations =>
page 238. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehicle at the time it was manufactured . For the location of
the label =>
page 238, fig. 148.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not
possible to see whether the radial tires used today are underinflated
just by looking at them. Therefore,
be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 242, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with the edge of the tire
gauge and keep checking the pressure until you reach the pressure
that is correct for the load (passengers and luggage) and kind of driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label
located on driver's side 8-pillar.
• Turn the valve stem cap counter -clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve.
• The tire pressures should only be checked and adjusted when
the tires are cold. The slightly raised pressures of warm tires must
not be reduced.
• Adjust the tire pressure to the load you are carrying.
• Reinstall the valve stem cap on the valve.

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

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 .

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 .
