I f you need to replace the remote contro l, or if you need to have it
repaired, you must see your authorized Audi dealer . Only then can
you use the key again.
P erson alizing the master key
When the ignition is turned off or when the vehicle is locked, various
convenience settings are stored automatically and assigned to the
key that was used. The se tti ngs that are assigned to the master key
are recalled automatically when the vehicle is unlocked, when the
door is opened or when the ignition is sw itched on .

Ap plies to vehic les : w it h side assist
Safety tips
T he s ide ass is t de tect io n may be limited whe n drivi ng a round
narrow street corners, on hilly streets, and under poor weather
c o ndition s.
It is possibl e that the radar sensors may also detect other ob jects,
suc h as h igh or s tagge re d guar drails. S
ide assist does not measure actua l lane width . The sys tem
assumes a fixed la ne wid th. Dete cti on in th e le ft an d rig ht l anes is
based on this assumed lane width . When d riv ing on narrow roads or
w hen driving to t he left or right of the ce nte r of a travel la ne, it i s
possible that vehicles will be detected that are
not in th e lane next
to the lane yo u are us ing.
& WARNING
• Improper reliance on the side assist system can cause colli ­
sions and serious personal injury :
- Never rely only on side assist when changing lanes.
- Always check rear view mirrors to make sure that it is safe to
change lanes .
• Side assist cannot detect all vehicles under all conditions ­
danger of accident!
• Side assist cannot detect vehicles in time to alert you when
they approach from behind at very high speed , or fall drop back
very quickly .
• The radar sensor's
vision can be reduced or entirely blocked by
rain , snow , and heavy spray . This can result in side assist not
adequately detecting vehicles or , in some cases, not detecting
them at all . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle .
• Please note that side assist indicates there are approaching
vehicles , or vehicles in your blind spot , only after your vehicle has
reached a driving speed of at least 19 mph (30 km /h).
• Side assist signal does not work around tight corners (turning
radius less than 328 feet , or 100 ml.
• Side assist is no replacement for the driver's full attention. The
driver alone is responsible for lane changes and similar driving
maneuvers . Always keep an eye on the direction you are traveling
and the relevant area around the vehicle. .,,_

cellular telephones and CB radios , et c.) must be performed by a
qualified technician who has the training and spec ial equipment
ne cessary .
• For any work on the airbag system , we strongly recommend
that you see your author ized Audi dealer or qual ified workshop .
• Never modify the front bumper or parts of the vehicle body.
• Always make sure that the side airbag can inflate without inter ­
ference :
- Never install seat covers or replacement upholstery over the
front seatba cks that have not been spe cific ally approved by
Audi.
- Never use additional seat cushions that cover the areas
where the side airbags inflate.
- Damage to the original seat covers or to the seam in the area
of the side airbag module must always be repaired immedi­
ately by an authorized Audi dealer .
• The airbag system can be activated only once. Afte r an airbag
has inflated , it must be replaced by an authorized Audi dealer or
qualified technician who has the te chnical information , training
and spe cial equipment necessary.
• The airbag sy stem can be deployed only once. After an airbag
has been deployed , it must be repla ced with new repla cement
parts designed and approved especially for your Audi model
version . Replacement of complete airbag systems or airbag
components must be performed by qualified workshops only .
Make sure that any airbag service action is entered in your Audi
Warranty
& Maintenan ce booklet under AIRBAG REPLACEMENT
RECORD .
• For safety reasons in severe accidents , the alternator and
starter are separated from the vehicle battery with a pyrotechni c
c ircuit interrupter.
- Work on the pyrotechni c circuit interrupter must only be
performed by a qualified dealer -risk of an accident!
& WAR NING (continued )
-If the vehicle or the circuit interrupter is s crapped , all appli­
cable safety precautions must be followed.
ffi For the sake of the environment
Undeployed airbag modules and pretensioners might be c lassified
as Pe rchlorate Material -special handling may apply, see
www .dtsc.ca .gov/hazardouswaste/perc hlo ra te . When t he veh icle or
parts of the restraint system inc luding airbag mod ules and safety
be lts wi th pre tensio ners are sc rapp ed, all ap plicab le laws a nd regu ­
l ations must be observed . Your authorized Audi dealer is fam iliar
wit h these requir ements an d we re co mmen d t hat yo u have your
dea ler perform this service for you. •
Other things that can affect Advanced Airbag
performance
Changing the veh ic le 's su spension system can change the way that
th e Advanced Air bag Syste m performs in a c rash. Fo r example,
using tire-rim combinations not approved by Audi, lowering the
v eh ic le, c hang ing the stif fness of th e suspe nsio n, in cl ud in g the
springs, suspension struts, shoc k absorbers etc . can change the
fo rces that a re m eas ure d b y the air bag senso rs and se nt to the elec ­
tronic control unit. Some suspension changes can, for example,
increa se the fo rce level s measured by the sen so rs and ma ke the
a irbag syste m dep loy in crash es in which it wou ld not dep loy if the
changes ha d not been made . Othe r kinds of change s may red uce
t he fo rce lev els measu red by the se nso rs a nd preve nt the airba g
from deploying when it should.
T he sens ors i n th e safe ty bel t buc kle for th e driver a nd fr ont

Battery replacement
The new battery must have the same specffications and
dimensi ons as the original equipment battery.
Intel ligen t energy management in your vehicle is responsible for
distributing the e lectrica l ene rgy throughout your vehicle
::} page 295. The intelligent energy management system will keep
the engine battery charged bette r then vehicles wi thou t this system .
To make sure the additional electrical energy is available once again
after you have changed the batte ry, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing . Your authorized Audi dealer will then
code the battery management cont rol unit .
If i t is no t possib le to use a ba ttery o f this type, the new battery m ust
have the same capacity, vo ltage (12 volts), amperage, construction
and plug seal ing.
When installing the battery, make sure the ignition and all electrica l
consumers are turned off .
0 Note
Make sure the ventilation hose on the side of the bat tery is
connected, otherwise fumes or battery acid can leak out .
W For the sake of the environment
Because of the problem of proper d isposal of a battery , we recom­
mend your authorized Aud i dea ler change the battery for you .
Ba tteries contain sulfuric acid a nd lead and must always be
disposed of properly in compliance with all environmental regula ­
tions. D isposi ng o f vehicle ba tteries i mproper ly is very dangerous to
the environment .•

U.S. DOT Tire Identification Number (TIN) and tire
manufacture date
This is the tire's "serial number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards . The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture . For example, the numbers 2208 mean that the tire was
produced in the 22th week of 2008. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others.
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades~ page 363.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans ­
mits this information to the tire pressure monitoring system. If you
are going to replace the wheel rims on your vehicle, make sure the new rims also have these sensors
. The sensors must be compatible
with the tire pressure monitoring system on your vehicle.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system
will not work properly. In this case, the tire pressure monitoring
system would not be able to monitor the tire pressure or warn you
if it is necessary.
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps .
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system, and is not recommended (cord material information
in molded on the tire sidewall).
Always check your tire pressure monitoring system indicator after replacing one or more tires on your vehicle. If the tire pressure
monitoring system indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring system, or some component of the
tire pressure monitoring system may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• 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 with special care and at
lower speeds . .,.
