weight of the driver and pas­ s engers that will be riding in
your vehicle .
3. Subtract the combined
weight of the driver and pas ­
s engers from
"XXX" kilo ­
grams or
"XXX " pound s
shown on the sticker
¢ page 198 , fig. 146 .
4. The resulting figure equals
the available amount of car­go and luggage load capa ci­
ty . For example, if the
"XXX''
amount equals 1400 lbs.
and there will be five 150 lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-750 (5
X 150) = 650 lbs .)
5. Determine the combined weight of luggage and cargo being loaded on the vehicle.
That weight may not safely
exceed the available cargo
and luggage load capacity
calculated in Step 4.

ing 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 ind icators . Worn tires must be replaced .
Different figures may apply in other countries
c::> ,& .
Tire pressure
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
c::> page 200.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear.
Rotating tires for more even wear
For a ll 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 rota­
tion intervals. Please remember the follow­
ing:
- Tire rotation interva ls may differ from the
vehicle serv ice intervals 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 manufacture r's suggested
t ir e rotation intervals .
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com ­
pared to all-wheel drive (quatt ro ® ).
- Please rotate t ires as shown
c::> fig . 149.
-Extra care must be taken when rotating di-
rect ion-specific tires
c::> page 226.
Wheel balancing
The whee ls on new vehicles are balanced.
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steering wheel. Unbalanced
wheels 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 installed.
Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi ­
cle. If tires show excessive wear, have the
whee l alignment checked by an authorized
Audi dealer or qualified workshop.
All Wheel Drive
Vehicles with quattro ® must a lways have tires
of the same size, construction and tread type .
For details see c::>page
154.
A WARNING
-Sudden tire fai lure can lead to loss of con-
trol, a crash and serious personal injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your r isk 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 w ith special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo­
ry." O ld used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire fai lure
and loss of vehicle control.

222 What do I do now ?
@ Tips
After a tire repair, have the sealant bottle
rep laced at a dealership . This restores full
functionality to the Tire Mob ility System.
What should I be
aware of when
changing a tire?
General information
The follow ing sections will provide you with
important information o n how to change a
tire using the vehicle tool kit.
However , we recommend that you have a
qua lified service center change the tire and
pe rform all work associated with changing it .

~ Use the hexagonal socket in the screwdriver
handle to screw in and tighten all wheel
bo lts
slightly .
~ Unscrew the alignment pin and insert and
t ighten the remaining wheel bolt s light ly
like the rest.
~ T urn the jack handle counter-clockw ise to
l ower the vehicle unti l the jack is fully re­
leased .
~ Use the whee l bolt w rench to t ighten al l
whee l bolts firmly <=>
page 222 . Tighten
them
crosswise, from one bolt to the (ap ­
proximate ly) opposite one, to keep the
whee l cente red.
Q;) Note
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
(D} Tips
Never use the hexagonal socket in the han­
dle of the screwdriver to loosen or t ighten
the wheel bolts .
- Pull the reversib le b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to t urn the whee l
bo lts .
- When mounting tires with
unid irectional
tread design
make su re the tread pat­
te rn is poi nted the r ight way
<=> page 226.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing s urfaces of both the wheel
and the hub. Rem ove a ll dirt from these
su rfaces before rem ounting the wheel.
Notes on wheel change
Please read the information <=> page 205 , New
tires and replacing tires and wheels ,
if you are
going to use a spare t ire which is different
from the tires on your ve hicle.
Afte r you change a tire :
What do I do now? 225
-Check the tire pre ssure on the spare imme­
diately after mounting.
- Have the whe el bolt tightening torque
checked with a torque wrench as soon a s
possible by your authorized Audi dealer or
a qualified service station.
- With steel and alloy wheel rim s, the wheel
bolt s are cor rectly tightened at a torque of
90 ft lb (120 Nm ).
- If you noti ce while changing a tire that the
wheel bolts are corroded and difficult to
turn , then they should be replaced before
you check the tightening to rque.
- Replace the flat tire w ith a new one and
have it installed on your vehicle as soon as
possible. Remount the whee l co ver.
Until then , dr ive with extra care and at re­
duced speeds.

instructions of the jumper cable
manufacturer. If in doubt, call for road
service.
- Jumper cables must be long enough so
that the vehicles do not touch.
- When connecting jumper cables, make
sure that they cannot get caught in any
moving parts in the engine compart­
ment.
- Before you check anything in the engine
compartment, always read and heed all
WARNINGS
<=> page 172, Engine com­
partment .
@ Note
Improper hook-up of jumper cables can ru­
in the generator.
-Always connect POSITIVE(+) to POSI­
TIVE(+), and NEGATIVE(-) to NEGATIVE
( - ) ground post of the battery manager
control unit.
- Check that all screw plugs on the battery
cells are screwed in firmly . If not, tighten
plugs prior to connecting clamp on nega­
tive battery terminal.
- Please note that the procedure for con­
necting a jumper cable as described
above applies spec ifically to the case of
your vehicle being jump started. When
you are giving a jump start to another ve­
hicle, do
