Intelligent Technology
gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or
too often. This could cause the brakes to get hot and diminish braking efficiency .
- Do not "ride the brakes" by resting your foot
on the pedal when you do not intend to
brake. This may cause the brakes to over ­
heat, premature wear and increased stop­
ping distance.
- Under certain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after washing the vehicle ,
the effectiveness of the brakes can be re­
duced . In winter, ice can accumulate on the
brake pads, linings, discs and drums . Care­
fully apply brakes for a test. Brakes will dry and ice coatings will be cleaned off after a
few careful brake applications.
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applications .
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Failure of one brake circuit will impair the
braking capability resulting in an increased
stopping distance. Avoid driving the vehicle
and have it towed to the nearest authorized
Audi dealer or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assistance.

is designed to record data re lated to vehicle dy ­
namics and safety systems for a short period of
time, typically 30 seconds or less . The EDR in this
vehicle is designed to record such data as :
- How various systems in you r vehicle were oper ­
ating;
- Whether or not the driver and passenger safety
belts were buckled/fastened;
- How fa r (if at all) the dr iver w as depressing the
acce lerator and/or brake peda l; and,
- How fast the ve hicle was travel ing.
These data can help prov ide a better understand­
ing of the c ircumstances in which c rashes and in­
juries occur. NO TE: E DR data are reco rded by your
ve hicl e only if a non -triv ia l crash si tuation occurs;
no data are recorded by the EDR under norma l
driving conditions and no pe rsonal data (e.g.,
name, gender , age, and crash location) are re ­
corded. However, other parties, such as law en­
forcement, could combine the EDR data w ith the
type of personally identifying data routine ly ac­
qu ired during a crash invest igation.
To read data recorded by an EDR, specia l equip­
ment is required, and access to the ve hicle or the
EDR is needed. In addit ion to the vehicle manu­
facturer, other parties, such as law enforcement,
that have the special equ ipment, can read the in­
formation if they have access to the vehi cle or the
E DR.
Some state laws restrict the retr ieval or down ­
loadi ng of data stored by ED Rs installed i n a vehi­
cle for the express purpose of retrieving data af­
ter a n accident o r crash event wi tho ut t he own­
e r' s consent.
Aud i will not access the EDR and/or s imilar data
or give it to othe rs -
- unless the vehicle owner (or lessee if the vehi­
cle has been leased) agrees; or
- upon the off icia l request by the police; o r
- upon the order of a court of law or a govern-
ment agency; o r
- for the defense of a laws uit throug h the judicial
discovery process.
- Audi may also use the data for research about
vehicle operation and safety performance or
Intellig ent Technology
prov ide the data to a third pa rty for research
purposes witho ut identifying the specific vehi­
cle or informat ion about the ident ity o f its own­
er or lessee and only after the recorded veh icle
data has been accessed.
Vehicle control m odules
You r vehicle is also eq uipped with a number of
electronic control modules for various vehicle
systems, such as engine management, emiss ion
contro l, airbags, and safety be lts.
These electronic contro l modu les record data
during norma l vehicle operation that may be
needed by trained techn ic ians for diagnostic and
repa ir purposes. The recording capab ility of these
modules is lim ited to data (no sound is record­
ed) . Only a small amount of data is actua lly re­
corded over a very limited period of time, or stor­
ed when a system fault is detected by a contro l
module . Some of the da ta stored may relate to
vehicle speed, direction, or b raking, as well as re ­
strain t system use and per formance in the eve nt
of a crash . Stored data can also on ly be read and
down loade d with specia l equipment that is di ­
rectly connected to the vehicle.

Driving sa fe ty
-Always drive with the head restraints i n
place and properly adjusted.
- Every person in the vehicle must have a
properly adjusted head restra int.
- Always make sure each person in the vehicle
properly adjusts their head restraint. Adjust
the head restra ints so the upper edge is as
even as possib le w ith the top of your head.
If that is not possib le, try to adjust the head
restra int so that it is as close to th is position
as possib le.
- 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, fi rst stop the vehicle safely before at­
tempting to ad just the head restr aint.
- Children must always be p roperly restrained
in a chi ld restrain t th at is appropria te fo r
their age and si ze
~page 137.
Examples of improper seating positions
The occupant restraint system can only reduce
the risk of injury if vehicle occupants are properly
seated.
I mp roper seating positions can cause se rious in­
ju ry or deat h. Safety belts can only wo rk when
they are p roperly posi tioned o n the body . Im­
p roper seating posi tions reduce t he effe ct iveness
of sa fety belts and w ill even increase the r isk o f
in jury and death by moving the safety be lt to crit­
ical areas of the body . Improper seating posit ions
also increase the risk of ser ious injury and death
when an airbag deploys and strikes an occupant
who is not in the prope r seat ing position. A driver
is respo nsible for the safety of all vehicle occu­
pants and especially fo r children. Therefo re:
~ Never allow anyone to assume an incorrect
seat ing pos ition w hen the veh icle is being used
~ .&. -
The follow ing bulletins list only some sample po­
sitions that will inc rease the risk of serious inju ry
and death. Ou r hope is that these examples will
make you more aware of seat ing pos it io ns that
a re dangero us.

Therefore , whenever the vehicle is moving :
-neve r stand up in the vehicle
- neve r sta nd on the seats
- neve r kneel on the seats
- never ride w ith the seatback recl ined
- neve r lie down on the rear seat
- neve r lean up against the instrument panel
- never s it on the edge of the seat
- neve r sit sideways
- neve r lean out t he window
- neve r put your feet o ut the window
- never put your feet on the instrument panel
- neve r rest your feet on the seat cushion or back
of the seat
- never ride in the footwell
- never ride in the cargo area
'
A WARNING
Imp roper seating positions inc rease the risk
of ser ious personal injury and death whenever
a veh icle is being used.
- Always make sure that all veh icle occupants
stay in a proper seating posit ion and are
properly restrained whenever the vehicle is be ing used .
Pedal area
Pedals
The pedals must alway s be free to move and
must never be interfered with by a floor mat or
any o ther object.
Mak e su re t hat all pedals move free ly w ithout in­
te rfe rence and t hat nothing prevents them from
r etur ning to their orig inal positions.
Only use floor mats that leave the pedal a rea free
and can be secured wi th floor ma t faste ne rs.
If a brake circuit fails, i ncreased brake pedal trav­
el is requ ired to bring the vehicle to a fu ll stop.
A WARNING
Pedals that ca nnot move freely ca n cause loss
of vehicle contro l and increase the r is k of seri­
ous injury.

...... N r--. N .... 0 0 ::, a:,
-Never place any objects in the driver's foot­
well. An object could get into the pedal area and interfere w ith pedal function. In case of
sudden braking or an accident, you would not be able to brake or accelerate!
- Always make sure that nothi ng can fall or
move into the dr iver's footwell.
Floor mats on the driver side
Always use floor mots that con be securely at­
tached to the floor mot 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
q .&, .
Use only floor mats that leave the pedal area un­
obstructed and that are firmly secured so that
they cannot slip out of position. You can obtain
suitable floor mats from your authorized Audi
dealer .
F loor mat fasteners are installed in your Audi.
Fl oor 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 pair safe operation of your vehicle in other ways.
A WARNING
Peda ls that cannot move free ly can result i n a
loss of vehicle control and increase the risk of
ser ious personal injury .
-Always make sure that floor mats are prop­ erly secured.
- Never place or install floor mats or other
floo r coverings in the veh icle that ca nnot be
prope rly secured in place to prevent them
from slipp ing and in terfering with the ped­
als or the abili ty to contro l the vehicle.
- Never place or insta ll floor mats or o ther
floo r coverings on top of already insta lled
floo r ma ts. Addit ional floor mats and othe r
coverings w ill reduce the size of the peda l
area and interfere with the pedals .
- Always properly reinstall and secu re floor
mats that have been taken o ut for cleaning .
Driving safety
-Always make sure that objects cannot fall
into the driver footwell while the vehicle is
mov ing. Objects can become trapped under
the brake pedal and accelerator pedal caus­ ing a loss of vehicle control.
Storing cargo correctly
Loading the luggage compartment
All luggage and other objects must be properly stowed and secured in the luggage compart­
ment.
Fi g. 103 Safe load pos ition ing: place heavy objects as low
and as fa r forward as poss ible.
Loose items in the luggage compartment can
shift suddenly, changing vehicle handling charac­
teristics. Loose items can also increase the risk of
serious personal injury in a sudden veh icle ma ­
neuver or in a collision .
.. Distribute the load evenly in the luggage com­
partment.
.,. Always place and properly secure heavy items in
the luggage compartment as low and as far for­
ward as possib le

leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
~ WARNING
-The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exha ust ta il pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other mater ial which can cause a fire.
- Do not apply additional undercoating or
rustproof ing on or near the exhaust mani­
fold, exhaust pipes, catalytic converter or
heat shields. During dr iv ing, the substance
used for undercoating could overheat and
cause a fire.
(D Note
- Be aware that just o ne tank filling with
lead ed fue l will already ser iously degrade
the pe rformance of the catalytic co nverter .
- Do not exceed the correct eng ine o il level
c::;, page 164.
- Do not drive until the fuel tank becomes
completely empty. The engine could mis­
fire. Unburned fuel could also get into the
exhaust system and th is cou ld cause the
c ata lytic converter to overheat.
- Do not turn off the ignition whi le the vehicle
i s mov ing.
- Do not continue to operate your veh icle un­
der these cond it ions, as otherwise fue l can
r each the cataly tic conve rte r. This cou ld re­
s ul t in ove rheating of the converter, req uir­
i ng its re placement.
- To assure efficient operation of the Em is ­
s ion Control System:
- Have your vehicle maintained properly and
in accordance with the service recommen­
dations in your Warranty

Ch eck ing and Filling
-Lack of proper ma intenance as well as im ­
p roper use of the vehicle w ill impair the
f u nct ion o f the emission control system
and could lead to damage.
® For the sake of the environment
Even when the Emiss ion Control System is op­
erating properly, the exhaust gas can have a
su lfur -like exhaust gas sme ll under some op­
erating states. This depends on the sulfur
content of the fuel being used. Us ing a d iffer­
ent brand of fuel may help, or f illing the tank
wi th lead-free supe r g rade gasoline.
