In correct wheel alignment
Inc orrect wheel alignment can cause excessive tire wea r, impairing
the saf ety of the vehicle . If tires s how excessive wear , have the
whee l alig nment chec ked by an autho rized A udi deale r or q ualif ied
workshop .
All Wheel Drive
Vehicles with quattro ® must always have tires of the same si ze ,
cons tructi on and tread type . For details see => page 218 .
& 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 indi cators .
• E specially in wet and slick driving situations , a preferably large
profile depth of the tires is necessary , and an approximately
similar profile depth of the front and rear axle tire s.
• The diminished driving safety , caused by too small of a tire
profile , is negatively perceivable especially in handling , in danger
of hydroplaning when driving through deep puddles and ponds ,
when driving around curve s, and in braking behavior.
• Worn t ires 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 a s
grease , oil , gasoline and brake flu id away from tires.
• Tires age even if they are not being used and can fail suddenly ,
espe cially 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
lowe r speeds.
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old u sed tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and los s of vehicle control. •

& WARNING
• You or your passengers could be injured while changing a
wheel if you do not follow safety precautions:
-Mounting the jack under the vehicle at any other place than
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 .

- 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.

[ i ] Tip s
Never try and use the hexagona l socket in the handle of the screw­
driver to loosen or tighten the wheel bolts.
• Pull the reversible b lade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bo lts.
• When mounting tires with
uni dire cti on al tread desig n make sure
the tread pattern is pointed the right way~
page 298.
• The whee l bolts should be clean and easy to turn. Check for dirt
and corrosion on the ma ting surfaces of both the wheel and the
hub. Remove all dirt from these surfaces before remounting the
wheel. •
Tires with unidirectional tread design
Tires with unidirectional tread design must be mounted
with their tread pattern pointed the right direction.

i n a sp ec ific dir ection
When using a spare tire with a tread pattern intended for use in a
specific direction, please note the following:
• The direction of rotation is marked by an arrow on the side of the
tire.
• If the spare tire has to be installed in the incorrect direction in the
event of a flat tire, use the spare tire on ly temporarily since the tire
will not be able to achieve its optimum performance characteristics
with regard to aquaplaning, noise and wear.
• We recommend that particular attention be paid to this fact
dur ing wet weather and that you adjust your speed to match road
conditions.
• Replace the flat tire with a new one and have it instal led on your
vehic le as soon as possible to restore the handling advantages of a
proper ly pointed direction-dependent tire. •
Notes on wheel change
Please read the information~ page 279, "New tires and replacing
tires and whee ls", if you are going to use a spare tire which is
