Con tro ls and eq uip­
ment
Audi magnetic ride is an e lectronically control led damping system.
This chassis system assists the driver by adapt ing to the particular
s ituation through imperceptible control processes . The
dampin g
provides individua l modulation of damping forces . For example,
with damping characteristics set to provide greater comfort ,
damping is set somewhat harder for a brief period on ly as required,
when rounding a curve and when braking.
Standard settin g
Select the standard setting if you prefer a suspension setting
emphasizing comfort .
Sp or t setting
Select the sport setting if you prefer a sporty suspension setting .
The LE D in the switch comes on to indicate sport setting .
[ i ] Tip s
The warning/indicator light in the instrumen t cluster comes on in
the event of a malfunction. Drive to the closest authorized Audi
dea le r as soon as possible and have the malfunction repaired .•

& 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 .
• Applies to vehicles with 6 -cylinder engine : For safety reasons in
severe accidents , the alternator and starter are separated from the
vehicle battery with a pyrotechnic 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 nothing interfere
with the safety belt buc kles so that the sensors can send the co rrect
i nformation about safety be lt use to t he electronic contro l 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. ..

Tire service life
The service life of tires depends on a Jot of different things
including proper installation and balancing, correct tire
pressure and driving style .

Tread Wear I nd ica tor ( TWll
Fig. 182 Tire tread:

Fi g. 1 83 Ro tati ng tir es
for mor e even wea r
The or iginal tires on your vehicle have 1/16 inch (1.6 mm) high "wear
indicators":::::, fig. 182 running across the 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. Dif ferent figures may apply in other countries:::::,&.
Tir e p re ss ure
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 :::::,
page 250.
Drivin g sty le
Driving fast around curves, heavy acce leration and hard braking
increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the same service life, we
recommend that the front and rear tires are rotated according to the
tire manufacturer's suggested tire rotation intervals . Please
r emember the following:
• Tire rotation interva ls may differ from the vehic le service inter ­
vals outlined in your Warranty
& Maintenance Booklet.
• The longer one tire is used in one location on the vehicle, the
more it wears at certain points; therefore, we recommend that you
follow the tire manufacturer's suggested tire rotation intervals.
• Vehicles with front -wheel drive experience mo re tread wear on
the front wheels compared to all-wheel drive (quattro®) .
• Please rotate tires as shown :::::, fig . 183.
• Extra care must be taken when rotating direction -specific tires
:::::, page 279.
Whe el b ala n cing
The wheels on new vehicles are balanced. However, various situa­
tions during everyday driving can cause them to become unba l­
anced, resulting in vibrations you can usual ly feel through the
steering wheel.
Unba lanced whee ls must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must a lso be reba lanced
when a new tire is installed.
