Tire pr essure
Inco rrect tire pressure causes prematu re wear and can cau se
sudden tire blow-out. For this reason, tire pressure must be checked
at least once a month
~ page 323 .
Driving style
Dr iv ing fa st around curves, heavy acceleration and hard brak ing
increase tire wear.
Rotating tire s for more even wear
For all four t ires on your vehic le to have the same service life, we
recommend that the front and rea r tires are rotat ed acc ord ing to the
tire manufacturer 's suggested tire rotation intervals. Please
remembe r the f ollo wi ng :
• Tire rotat ion i nterva ls m ay d iffer from the vehic le serv ice inte r­
vals outl ined in your Maintenance and Warranty Book let.
• The longer one tire is used in one location on the vehicle, t he
more it wears at certain points; the refo re, we recommend that you
f ollow the tire manu facturer's sug ges ted t ire rotat ion i nte rvals.
• Vehicles with fro nt-w hee l dr ive e xper ience more tread wear on
the front wheels compared to all -wheel drive (quattro®l .
• Please rotate tires as sh ow n~
page 32 7, fig. 250 .
• Extra care must be taken when rotating direction -specific tires
~ pag e 349 .
Wheel balancing
T he w hee ls o n new v ehic les are balanced. However, various s itua ­
tions during everyday driving can cause them to become unba l­
anc ed, resu lti ng in vib rati ons yo u ca n us ually feel thro ugh t he
steer ing whee l.
U nba la nce d w heels must b e re ba lance d to avoid e xcessive wea r on
steering, suspension and tires. A whee l must a lso be reba lanced
when a new tire is installed.
Incorrect wheel alignment
Incorrect w hee l al ig nm ent ca n cau se e xcess ive ti re wea r, impa iring
t h e s afety of th e veh ic le. If t ires s how excessive w ear, have the
w hee l a lig nme nt checke d by a n autho rize d Aud i deale r or qualifie d

All Wheel Drive
Vehic les with quattro® must always have tires of the same size,
co nstruct ion an d tread ty pe. For deta ils see ~
page 268.
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and increase your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• 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 . •

& WARNING
Always adjust your driving to the road and t raffic condit ions .
Never let the good a cceleration of the winter tires and all -wheel
dri ve tempt you into tak ing extra ri sk s. Always remember :
• When braking, an all -wheel drive vehicle handles in the same
way as a front drive vehicle .
• Drive carefully and redu ce your speed on icy and sli ppery roads ,
even winter tires cannot help unde r bla ck ice conditions.
c£> For the sake of the environment
Use summer tires when weather conditions permit. They are
quieter, d o no t wear as quick ly a nd re duce fuel consump tio n.•

A wheel change is not complete without the doing the
following.
- Store and secure the wheel you replaced in the spare
wheel well.
- Replace the tools and the jack in their proper location.
-Check the tire pressure on the spare wheel immediately
after mounting it.
- As soon as possible, have the
tightening torques on all
wheel bolts checked with a torque wrench. The correct
tightening torque is 90 ft lb (120 Nm).
- Have the flat tire
replaced as soon as possible.

& WARNING
• You or your passengers could be injured while changing a
wheel if you do not follow these safety precautions:
- Positioning the jack under the vehicle at any other place than
those indicated above may damage the vehicle or may result in
personal injuries.
- A soft or unstable surface under the jack may cause the
vehicle to slip off the jack. Always provide a firm base for the
jack on the ground.
If necessary, use a sturdy board under the
jack.
- On hard, slippery surface (such as tiles) use a rubber mat or
similar to prevent the jack from slipping.
• To help prevent injury to yourself and your passengers: -Do not raise the vehicle until you are sure the jack is securely
engaged.
- Passengers must not remain in the vehicle when it is jacked
up.
- Make sure that passengers wait in a safe place away from
the vehicle and well away from the road and traffic.
- Make sure jack position is correct, adjust as necessary and
then continue to raise the jack.
[ i ] Tips
Before changing the wheel, you must activate the jacking mode, so
that the automatic controls for the Adaptive Air Suspension do not
make it more difficult to lift the vehicle with the jack =>
