Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv­
ing style.
Fi g. 2 39 Tire tread: tre ad wea r ind icators (TWI)
F ig. 240 Rotat ing t ires for more ev en wea r
Tread Wear Indicator (TWI)
The o rigi na l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
.... N M
c::> fig . 239 running across the tread. Depend ­
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p res sure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 280.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined 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 manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 240.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 302 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unbal ­
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
and t ires. A whee l must also be reba lanced
when a new tire is insta lled.
Incorrect wheel alignment
Incor rect wheel alig nment can cause exces ­
sive tire wear, impairing the safety of the veh i­
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop .
All-wheel driv e
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .

@ Tips
-The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump start ing or charging the
battery, never connect the negative
ground cable to the battery negative
post because the battery manager sys­
tem must be able to detect the battery's
state of cha rge. A lways connect the neg­
ative g round cab le to the negative
gro und post o f the battery manage r con­
trol uni t.
