Replacing tires
F or vehicles w it h all whee l dr ive, only wheels w ith
the same ro lling circumference should be used .
Avoid using tires with different tread depths
~ page 332, New tires or wheels.
A WARNING
- Also, in vehicles with all wheel drive, adapt your dr iv ing style to the current road and
traff ic conditions. Do not let the increased
safety provided tempt you into tak ing risks,
because th is increases the r isk of an acci­
dent .
- The braking ability of your veh icle is limited
to the tract ion of the wheels. In this way, it
is not diffe rent from a two wheel dr ive vehi­
cle. Do not be tempted to accelerate to a
high speed when the road is slippery, be­
cause this increases the risk of an accident.
- Note that on wet streets, the front wheels
can "hydroplane" if driving at speeds that
are too high . Unlike front whee l drive
vehicles, the engine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, adapt your speed to the
road conditions to reduce the risk of an acc i­
dent .
Energy management
Your vehicle is equipped with an intelligent ener­
gy management system for distributing electrici­
ty . This s ignificantly improves the starting ab ility
and increases the vehicle battery life .
(D Tips
- If you drive short distances frequently, the
vehicle battery may not charge enough
while dr iving . As a resu lt, convenience func­
tions for elect rical equipment may be tem­
porarily unavailable.
- The vehicle battery will gradua lly drain if
the vehicle is not driven fo r long pe riods of
time, or if electrical equipment is used
when the engine is not running . To ensure
that the vehicle can still be started, the electrica l equipment will be reduced or
switched off.
Intelligent Technology
Notice about data
recorded by the Event
Data Recorder and
vehicle control modules
Event Data Recorder
T his vehicle is equipped with an Event Data Re­
corder (EDR). The main purpose of an EDR is to
record, in certain crash or near crash-like situa­
tions, such as an airbag deployment or hitting a road obstacle, data that will assist in understand­
ing how a vehicle's systems performed. The EDR
is designed to record data related to vehicle dy ­
nam ics and safety systems for a short per iod of
t ime, typ ically 30 seconds or less. The EDR in this
vehicle is designed to record such data as:
- How various systems in your vehicle were oper­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How far (if at all) the driver was depressing the
accelerator and/or brake pedal; and,
- How fast the vehicle was traveling.
These data can help provide a better understand­
ing of the circumstances in which crashes and in ­
juries occur. NO TE: EDR data are recorded by your
vehicle only if a non-trivial crash situation occurs;
no data are recorded by the EDR under normal
driv ing cond itions and no personal data (e.g .,
name, gender, age, and crash location) are re­
corded. However, othe r parties, such as law en­
forcement, could comb ine t he EDR data with the
type of personally identifying data routinely ac­
quired during a crash investigation.
T o read data recorded by an EDR, special equip­
ment is required, and access to the vehicle or the
EDR is needed. In addition to th e ve hicle manu­
facturer, other parties, such as law en forcement,
that have the special equipment, can read the in ­
formation if they have access to the vehicle or the
EDR.
Some state laws restrict the retrieval or down­
l oading of data stored by ED Rs installed in a vehi ­
cle for the express purpose of retrieving data af­
ter an accident or crash event without the own- er 's consent .

Drivin g saf ety
- Never attempt to adjust head restraint
wh ile driving. If you have dr iven off and
must adjust the driver headrest for any rea­
son, first stop the vehicle safely before at­
tempting to ad just the head restra int.
- Children must always be properly restrained
in a child restraint that is appropriate for
their age and size
c> page 291 .
Examples of improper seating positions
The occupant restraint system can only reduce
the risk of injury if vehicle occupants are properly
seated .
Improper seating positions can cause serious in­
jury or deat h. Safety belts can only work when
they are properly positioned on the body . Im­
proper seating positions reduce the effect iveness
of safety belts and w ill even increase the r isk of
i n ju ry and death by moving the safety be lt to crit­
ical a reas of t he body. Improper seat ing posit ions
a lso increase the risk of serious injury and dea th
when an airbag deploys and strikes an occupant
who is not in the proper seating position. A driver is responsib le for the safety of all vehicle occu­
pants and especially for children. Therefore :
~ Never allow anyone to assume an incorrect
seating position when the vehicle is being used
c> & .
The fo llowing bulletins list only some sample po ­
sitions that wi ll increase the risk of serio us inj ury
and death. Our hope is that these examples will
make you more aware of seating posit ions that
are dangerous.
The refore, when ever th e vehicle i s mo ving :
-never stand up in the vehicle
- never s tand on the seats
- never knee l on the seats
- never r ide with the seatback reclined
- never lie down on the seats
- never lean up against the instrument pane l
- never sit on the edge of the seat
- never sit sideways
- never lea n ou t t he w indow
- never put yo ur feet out the window
256
-never put your feet on the instrument panel
- neve r rest your feet on the seat c ushion or bac k
o f the seat
- neve r ride in the footwell
- never ride in the cargo area
.8, WARNING
Imp roper seating positions in cr ease the risk
of ser ious personal inju ry and dea th whenever
a veh icle is being used.
- Always make sure that all veh icle o ccupants
s tay in a proper sea ting posit ion and a re
proper ly restrained whenever the vehicle is
being used .
Pedal area
Pedals
The pedals must always be free to move and
must never be interfered with by a floor mat or
any other object.
Make sure that all pedals move free ly without in­
terference and that nothing prevents them from retur ning to their or ig inal pos itions .
Only use floor mats that leave the pedal area free
and can be secured with floor mat fasteners.
If a bra ke circuit fails, increased brake pedal trav ­
e l is req uired to bring the vehicle to a fu ll stop.
.8, WARNING
Pedals that cannot move freely can cause loss
of vehicle contro l and increase the r isk of seri­
ous injury.
- Never p lace any objects in the driver's foot­
wel l. An object could get into the pedal area
and interfere with pedal funct ion. In case of
sudden braking or an acc ident, you would
no t be able to brake o r acce le rate!
- Always make sure that nothing can fall or
move into the driver's footwell.

Floor mats on the driver side
Always use floor mats that can be securely at­
tached to the floor mat fasteners and do not in­
terfere with the free movement of the pedals .
.,. Make sure that the floor mats are properly se­
cured and cannot
move and interfere with the
pedals ¢&_ .
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of pos it ion . You can obtain
suitab le floor mats from your authorized Audi
deale r.
F loor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached
to these fasteners. Proper ly securing the floor
mats will prevent them from sliding into posi­
tions that could interfere with the pedals or im­
pa ir safe operation of your vehicle in other ways.
A WARNING
Peda ls that cannot move free ly can result in a
loss of vehicle control and increase the risk of
ser ious personal in jury.
- Always make sure tha t floor mats are p rop­
erly sec ured.
- Never place o r install floor mats or other
floor coverings in the ve hicle that cannot be
prope rly secured in place to prevent them
from slipp ing and interfering with the ped­
als or the ability to control t he vehicle .
- Never place o r inst all floo r m ats or o ther
floor coverings on top of already insta lled
floo r mats. Additional floor mats and other
cove rings wi ll reduce the size of the peda l
area and interfere with the pedals.
- Always properly reinstall and secure floor
mats that have been taken o ut for cleaning.
- Always make sure that objects cannot fa ll
into the dr iver footwell while the veh icle is
moving. Objects can become trapped under
the brake peda l and accelerator peda l caus­
ing a loss of veh icle control.
