To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calc ium . Always add window cleaner to the wa­
ter. When the outside temperatures a re cold, an
anti-freezing agent should be added to the water
so that it does not freeze.
- The concent ration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. A con­
cent ration that is too high can lead to vehi­
cle damage.
- Never add radiator anti-freeze or other addi­
tives to the washer fluid.
- Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint .

New tires or wheels
Audi recommends having all work
on tires or wheels performed by an authorized Audi dealer or au­
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace­ ment parts.
.,,. New tires do not yet have the
optimum gripp ing properties .
Drive carefully and at moderate
speeds for the first 350 miles (500 km) with new tires.
.,,. Only use tires with the same de­
sign, size (rolling circumference)
and as close to the same tread
pattern as possible on all four
wheels.
.,,. Do not replace tires individually .
At least replace both tires on the
same axle at the same time.
.,,. Audi recommends that you use
Audi Original Tires . If you would
like to use different tires, please note that the tires may perform ...

differently even if they are the
same size
c::> .,&..
~ If you would like to equip your
vehicle 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
c::> ,& .
If the spare tire is different from
the regular tires installed on the
vehicle - for example, if winter
tires or wide tires are installed -
then only use the spare tire tem­ porarily in case of emergency and
drive carefully while it is in use. It
should be replaced with a regular
tire as soon as possible.
Applies to: vehicles with all wheel
drive: 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 dam­
aged by different wheel speeds. For this reason, in case of emer­
gency, only use a spare tire that has the same circumference as
the regular tires.
174
A WARNING -
-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 abso­
lutely 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 al­low enough air circulation to
cool the brake system. If they
do not, this could increase the risk of an accident.
Tire wear/damage
Fig. 145 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 dea ler
or authorized Audi Service Facili-
l ) Obey any applicable regulations in your
country.
Wheels
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 d irec­
tion
i:::> fig. 145. The letters "TWI "
or triang les on the tire sidewall
indicate the location of the tread­
wear indicators.
The tires have reached the mini­ mum tread depth
l ) when they
have worn down to the treadwear
indicators. Replace the tires with
new ones
i:::> .&..
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 ..,.
175

Wheels
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 196.
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
s ide, drive slowly and carefully to
the nearest authorized Aud i 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
t ires can reduce driving safety.
This can increase the risk of an
accident because it has a nega­
t ive effect on handling, driving
through curves, and braking, and because it increases the
176
risk of hydroplaning when driv­
ing through deep puddles.

disassemble them ¢.&. .
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an acc ident. For the correct tightening specifi ­
cation, see ¢
page 192, After changing a
wheel .
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of grease.
- Only use wheel bo lts that fit the rim .
- Always have damaged r ims repa ired by an
authorized Audi dealer o r autho rized Aud i
Service Facility . Never repair or d isassemble
r ims yourself, because this inc reases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be­
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac­
tion on ice and snow .
... Use w inter t ires on all fo ur wheels .
... Only use winter t ires that are approve d for your
v ehicl e.
... Please note that the maximum permitted
speed may be lower with winter tires¢.&.
