CD Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
T he new battery must have the same specifica­
t ions and dimensions as the original equipmen t
bat tery.
Int elli g ent en ergy managem ent in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
r=> page 195. The intelli­
gent energy management system will keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the addit ional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture on ly (the same as those installed at the
time your vehicle was delivered). Specifications
are listed on the battery housing. Your author­
i z ed dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re ­
placing the battery .
The new battery must have the same capacity,
voltage (12 volts) , amperage, construction and
plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are sw itched
off.
CD Note
- Make sure the ventilation hose on the s ide
of the battery is connected, otherw ise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery . Installing a d ifferent type of bat­
tery can cause problems in the vehicle elec -
234
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery .
- Battery mounts and clamps m ust always be
secured correctly.
- Read and follow the warnings under
¢ page 231, Working on the battery before
performing any work on the battery .
@ For the sake of the environment
Because of the p roblem of proper disposal of
a battery, we recommend your authorized
A udi dealer change the battery for you . Bat­
teries contain sulfur ic acid and lead and must
a lways be disposed of properly in compliance
with all environmental regulations . Disposing
of veh icle batteries improperly is very danger­
ous to the environment .

Wheels and Tires
General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap ­
proach the curb at an angle.
~ Have faulty tires or rims re­
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running direction can be maintained if
they are reinstalled .
~ Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as possible.
(i}) Note
-Please note that summer and
winter tires are designed for
the conditions that are typical i n those seasons. Audi recom­
mends using winter tires dur­
i ng the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
236
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi­
tions. The surface of the r ims
does not have sufficient corro­
sion protection for th is and
could be permanently dam­
aged by road salt or similar
substances.

_& WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinf lat ­
ed.
Tire pressure monitoring system
U) General notes
Applies to: vehicles with tire pressure monito ring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat­
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflat ion pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la­
bel, you should determine the proper tire infla­
tion pressure fo r those tir es) .
As an added safety feature, your vehicle has been
equipped with a t ire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell­
tale when one or more of your tires is significant­
ly under-inflated . Accord ingly, when the low tire
p ressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop­
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is comb ined w ith the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain cont inuous ly
illuminated. This sequence will continue upon
254
subsequent vehicle start-ups as long as the mal­
function exists.
When the malfunction indicator is illum inated,
the system may not be able to detect or s ignal
low tire pressure as intended . TPMS malfunctions
may occur for a variety of reasons, including the
i nstallation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
whee ls allow the TPMS to continue to function
properly.
If the Tire Pressure Monitoring System
indicator appears
Applies to: vehicles with tire pressure monitoring system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too low
or if there is a system malfunction.
Fig . 209 Instrument cl uste r: indicator light with me ssage
Using the ABS sensors, the tire pressure monitor­
ing system compares the tire tread c ircumfer­
ence and v ibration characteristics of the individu­
al tires.
If the pressure changes in one or more
ti res, this is ind icated in the instrument cluster
display with an indicator light
[I] and a message.
If only one tire is affected, the locat ion of that
tire will be indicated.
The tire pressures must be stored in the Infotain­
ment system again each time the pressures
change (switching between partial and full load
pressure) or after changing or replacing a tire on
your vehicle ¢
page 255. The tire pressure moni­
tor ing system only monitors the tire pressure you
have stored . Refer to the t ire pressure label for ..,.

the recommended tire pressure for you r ve hicle
¢ page 246, fig . 208.
T ire tread circumference and v ibrat ion character­
istics can change and cause a ti re pressure warn­
ing if :
- the tire p ressure in one o r more tires is too low.
- the tire has structura l damage .
- the tire was replaced or the tire pressure was
changed and it was not stored¢

fir st a lig nme nt pin .
264
-Pull the reversible blade from the screwdriv­
er before you use the hexagonal socket in
the handle to turn the wheel bolts.
- When mounting tires with
unidirectional
tread design
make sure the tread pattern is
pointed the right way¢
page 264.
-The wheel bolts should be clean and easy to
turn. Check for dirt and corrosion on the
mating surfaces of both the wheel and the
hub. Remove all dirt from these surfaces be­
fore remounting the wheel.
Tires with unidirectional tread design
Tires with unidirectional tread design mus t be
mounted with their tread pattern pointed in the
right direction .
Using a spare tire with a tread pattern
intended for use in a specific direction
When using a spare tire with a tread pattern in­
tended 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 incor­
rect direction, use the spare tire only tempora­
rily since the tire will not be able to achieve its
optimum performance characteristics with re­
gard to aquaplaning, noise and wear.
- We recommend that you pay particular atten ­
tion to this fact during wet weather and that
you adjust your speed to match road condi­ tions.
- Replace the flat tire with a new one and have it
installed on your vehicle as soon as possible to
restore the handling advantages of a unidirec­
tional tire.
