as sulfur ic acid and lead. Contact an author­
i zed Audi dealer or authorized Audi Service
Fac ility for more informat ion.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually sca led
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of
time<=> page 145 . Some convenience
funct ions, such as interior lighting or power seat
adjustment, may not be available under certain
circumstances . These convenience functions will
be available again once you switch t he ignition on
and start the engine .
Even when electrical equipment is switched off,
the equipm ent can still drain the vehicle battery
if the vehicl e is not driven for long periods of
time. Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery.
The vehicle battery must be charged every month
to reduce the risk of this happening
<=> page 323.
Contact an authorized Aud i dealer or authorized
Audi Service Fac il ity for more information.
Winter operation
Cold weather places higher demands on the vehi­
cle battery. This results in reduced starting abili­
ty. Have the vehicle battery checked by an au­
thorized Audi dealer or authorized Audi Service
Fac il ity before the cold time of year .

New tires or wheels
Audi recommends having all work
on t ires or wheels performed by
an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
know ledge and are eq uipped with
the required too ls and rep lace­
ment parts.
... New t ires do not yet have the
optim um gripping properties.
Drive carefully and at moderate
speeds for the first 35 0 m iles
(500 km) with new tires .
... Only use tires with the same de­
sign, size ( rolling circumfer ­
ence) , and as close to t he same
tread pattern as possible on a ll
four wheels .
...
Do not replace tires individually.
At least replace bo th tires on the
same axle at the same time .
... Audi recommends that you use
Audi O riginal Tires. If you would
like to use di fferent tires, please
note that the tires may perform

differently even if they are the
same
size ¢,&. .
.,,. If you would like to equip your
vehic le with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase¢ ,&..
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporari ly in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds. For this rea­
son, in case of emergency, only
use a spare tire* that is the same
circumference as the regular
tires.
A WARNING
-
-Do not use steel rims that are 17 inches or larger. Other-
Wheels
wise, damage to the vehicle
and an accident could result .
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not
possible to use tires from oth­
er vehicles
-in some cases,
you cannot even use tires from
the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
-Only use tires that are more than six years old when abso­lutely necessary and drive
carefully when doing so.
-Do not use run-flat tires on
your vehicle. Using them when

not permitted can lead to ve­
hicle damage or accidents.
-If you install wheel covers on
the vehicle, make sure they al­
low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 267 Tire profile: treadwear indica­
tor
Tire wear
Check the tires regularly for wear.
-Inflation pressure that is too low
or high can increase tire wear
considerably.
-Driving quickly through curves ,
rapid acceleration and heavy
braking increase tire wear.
-Have an authorized Audi dealer
or authorized Audi Service Facili-
l) Obey any applicable regulations in your
country.
334
ty check the wheel alignment if
there is unusual wear.
-Have the wheels rebalanced if an imbalance is causing noticeable
vibration in the steering wheel.
If you do not, the tires and other
vehicle components could wear more quickly .
Treadwear indicator
Original equipment tires contain
treadwear indicators in the tread pattern, which are bars that are 1/16 in (1.6 mm) high and are
spaced evenly around the tire per­ pendicular to the running direc­
tion
¢ fig. 267. The letters "TWI"
or tr iangles on the tire sidewall
indicate the location of the tread­
wear indicators.
The t ires have reached the mini ­
mum tread depth
l ) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
¢ .&. -
Tire rotation
Rotating the tires regularly is rec­
ommended to ensure the tires
wear evenly. To rotate the tires,
install the tires from the rear axle

on the front axle and vice versa.
This will allow the tires to have approximately the same length of
service life.
For unidirectional tires, make
sure the tires are installed accord­ ing to the running direction indi­
cated on the tire sidewall
¢ page 355.
Hidden damage
Damage to tires and rims can of­
ten occur in locations that are
hidden. Unusual vibrations in the
vehicle or pulling to one side may indicate that there is tire damage.
Reduce your speed immediately.
Check the tires for damage. If no
damage is visible from the out­
side, drive slowly and carefully to
the nearest authorized Audi deal­ er or authorized Audi Service Fa­
cility to have the vehicle inspect ­
ed.
A WARNING
Tread that has worn too low or
different tread depths on the
tires can reduce driving safety.
This can increase the risk of an
accident because it has a nega­
tive effect on handling, driving
through curves, and braking, and because it increases the
Wheels
risk of hydroplaning when driv­
ing through deep puddles.

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easi ly.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consist of multiple pieces . These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
d isassemble them
C> _&. .
_& WARNING
Wheel bolts that are tight ened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident. For the correct tightening specifi­
cation, see
e> page 356, Finishing.
-Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease.
- Only use wheel bolts that fit the rim.
- Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility . Never repair or disassemble
rims yourse lf, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions . Be ­
cause of their construction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow.
"'Use winter tires on all four wheels .
"'Only use winter tires that are approved for your
vehicle .
"'Please note that the maximum permitted
speed may be lower with winter tires
e> & in
General information on page 325.
An author­
ized Audi dealer or authorized Audi Service Fa­
cility can inform you about the maximum per­
mitted speed for your tires .
"'Check the tire pressure after installing wheels
¢page 335.
340
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.16 in (4 mm) . The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
@) For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, tire wear and fuel
consumption .
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun­
tries where winter tires are required, only
winter tires with the
& symbol may be per­
mitted.
Snow chains
Snow cha ins not only improve the driving in win­
ter road conditions, but also the braking.
"'Only install snow chains on the rear wheels.
"' Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
"'Note the maximum speed of 30 mph (SO km/
h). Note the local regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authorized Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains.
Use
fine-mesh snow chains. They must not add
more than 0 .53 in (13.S mm) in height, including
the chain lock.
You must remove the snow chains on roads with­
out snow . Otherwise, you could impair driving
ability and damage the tires .
_& WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
