78 On the road
the distance between your vehicle and
other vehicles.
- For safety reasons, the cruise control
should not be used in the city, in stop­
and-go traff ic, on twist ing roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro­
planing) -risk of accident .
- Turn off the cruise control temporarily
when entering turn lanes, highway exit
lanes or in construction zones.
- Please note that inadvertently "resting" your foot on the accelerator pedal causes
the cruise control not to brake. This is
because the cruise control is overridden
by the driver's acceleration.
({) Tips
The cruise control cannot maintain a con­
stant speed when driving downhill. The ve­
hicle will accelerate under its own weight. Downshift to a lower gear or use the
brakes to slow down .
Changing speed
.. Press leve r in the 0 or O direction
¢ page 77, fig. 85 to increase or decrease
your speed.
.. Release the lever to save that speed.
You can also press the accelerator pedal down
to increase your speed, e.g. if you want to
pass someone. The speed you saved earlier
will resume as soon as you release the acceler­
ator pedal.
If, however, you exceed your saved speed by
5 mph (10 km/h) for longer than 5 minutes,
the cruise control will turn off temporarily .
The symbol will go out but the saved speed
will be retained .
Presetting your speed
You con preset your desired speed while the
vehicle is not moving .
.. Turn on the ignition . ..
Pull lever into position
(D ¢ page 77,
fig. 85.
.. Press the lever in the 0 or O direction to
increase or decrease your speed.
.. Release the lever to save that speed.
This function makes it possible, for example,
to save the speed you want before driving on
the highw ay. Once on the highway, activate
the cruise control by pulling the lever toward
(D.
· Switching the system off
Temporary deactivation
.. Press the brake pedal, or
.. Press the lever into position @(not clicked
into place)
¢ page 77, fig . 85 , or
.. Drive for longer than 5 minutes at more
than 5 mph (10 km/h) above the stored
speed.
Switching off completely
.. Press lever into position @ (clicked into
place), or
.. Switch the ignition
off.
The system retains the saved speed if you de­
activate the cruise control temporarily. To re­
sume the saved speed, release the brake ped­
al and pull the leve r to position
(D .
Switching the ignition off erases the saved
speed.
_& WARNING
You should only return to the saved speed
if it is not too fast for the current traffic
conditions -risk of an accident!

If you have selected a lower gear than the cur­
rent one, the transmission will only shift down
when the engine cannot be overspeeded .
If kick-down is actuated, the transmission
shifts into a lower gear independent ly of
speed and engine rpm .
Steering wheel with Tiptronic controls
The selector paddles allow the driver to keep
both hands on the steering wheel when shift­
ing gears.

Kick -down feature
The kick-down feature allows maximum ac­
celeration .
If you depress the accelerator pedal fully be­
yond the full-throttle position, the transmis­
sion automatically downshifts one gear, de ­
pending on vehicle speed and engine rpm. The
upshift into the next higher gear takes place
as soon as the maximum specified engine
speed is reached.
_&. WARNING
Please note that the drive wheels can spin
if the kick-down is used on a smooth slip­
pery road -risk of sk idding!
Launch Control Program
The Launch Control Program permits maxi­
mum acceleration.
In order to use Launch Control, the ASR (Anti­
Slip Regulation) must be disabled. When ASR
is disabled, the ESC warning/indicator light
I) in the instrument cluster illuminates. So
that Launch Control can be used, the engine must be at operating temperature and the
steering wheel must not be turned .
.. With the engine running, briefly press the
ESC button . The message "Stabilization pro­
gram off" or "Sport control Warning! Re­
stricted stability" in the driver information
system display.
.. Shift the gear lever to "S" or the tiptron ic
position .
.. Step on the brake pedal with your left foot
and keep the brake pedal fully depressed for
at least one second .
.. With your right foot, step on the accelerator
to the wide-open throttle position or Kick­

A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it deploys. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always adjust the driver's seat and the
steering wheel so that there are at least
4 inches (10 cm) between the knees and
the lower part of the instrument panel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal injury if the driver's airbag inflates.
- Never hold the steering wheel at the
12 o'clock position or with your hands at
other positions inside the steering wheel
rim or on the steering wheel hub. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag in­
flates
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving. Your seat may move unexpect-
Driving Safely 93
ed ly and you could lose control of the ve­
hicle .
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in­
jury due to incorrect positioning of the safety belt and improper seating posi­
tion .
- Children must always ride in child seats
c:> page 129 . Special precautions apply
when installing a child seat on the front passenger seat
c:> page 108.
Proper seating position for the front
passenger
The proper front passenger seating position
is important for safe, relaxed driving .
For your own safety and to reduce the risk of
injury in the event of an accident, we recom­
mend that you adjust the seat for the front
passenger to the following position :
~ Adjust the angle of the seatback so that it is
in an upright position and your back comes
in full contact with it whenever the vehicle is
moving.
~ Adjust the head restraint so that the upper
edge is as even w ith the top of your head as
possible but not lower than eye level and so
that it is as close to the back of your head as
possible
c:> page 94.
~ Keep both feet flat on the floor in front of
the front passenger seat .
~ Fasten and wear safety belts correctly
c:> page 103.
For detailed information on how to adjust the
front passenger's seat, see
c:> page 59 .
A WARNING
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of

Pedal area
Pedals
The pedals must al ways be free to move and
must n ever be interfered with by a floor mat
or any other object.
Make sure that all pedals move freely without
interference and that nothing prevents them
from returning to the ir original positions .
Only use floor mats that leave the peda l area
free and can be secured with floor mat fasten­
ers .
If a brake circuit fails, increased brake peda l
travel is required to bring the vehicle to a full
stop.
A WARNING
Pedals that cannot move freely ca n cause
loss of vehicle control and increase the r isk
of serious injury.
- Never place any objects in the driver 's
footwell. An object could get into the
peda l area and interfere w it h pedal func­
ti on. In case of s udden braki ng or an ac­
cident, you would not be ab le to bra ke or
accelera te!
- Alw ays make su re th at noth ing c an f all
or move into the dr iver's footwe ll.
Floor mats on the driver side
Always use floor mats that can be securely
at tached to the floor mat fasteners and do
no t interfere with the free movement of the
pedals.
.,. Make su re tha t the floor mats are properly
sec ured and cannot move and inte rfere w ith
the pedals ~.&_ .
Use only floor mats that leave t he pedal a rea
unobstr ucted and that a re firmly secured so
that they cannot s lip out of posi tion. Yo u can
obtain suitable floor mats from your author ­

Fl oor mat f asteners a re i nstalled in you r A udi . Floor mats used in yo
ur vehicle must be at ­
tached to these fasteners . Properly securing
t h e floor mats will prevent them from sliding
into positions that could interfere with the
pedals or impair safe operat ion of your vehicle
i n other ways.
A WARNING ,-
Pedals tha t ca nnot move free ly can result
i n a loss of vehicle control and inc rease the
r isk of ser ious perso na l inju ry.
- Always make sure that floor mats are
p roperly secu red.
- Never p lace or install floor mats o r other
f loor cove rings in th e vehicle that cannot
be pro pe rly secured in p la ce to prevent
them from slipping and interfer ing wi th

- Never use cushions, pillows, blankets or
similar items on t he front passenger
seat . The add itional padd ing will prevent
the weight-sensing mat in the seat from
accurately reg istering the ch ild restra int
or person on the seat and prevent the
Advanced Airbag System from function­ ing properly .
- If you mus t use a child restra int on the
front passenger seat and the ch ild re­
straint manufacturer's instructions re ­
quire the use of a towel, foam cushion or
something else to properly position the
child restraint, make certa in that the
PA SSENGER AIR BAG OFF light comes
on and stays on whenever the child re­
st raint is installed on the front passen­
ger seat .
- If the
PA SSENGER AIR BAG OFF light
does not come on and stay on, have the
airbag system inspected by your Audi
dealer.
How the Advanced Airbag System
components work together
The front Advanced Airbag System and the
side airbags s upplement the protection of ­
fered by the front three-point safety be lts
with pretensioners and load limiters and the
adjustab le head restra ints to he lp reduce the
risk of injury in a w ide range of acc ident and
crash situat ions . Be sure to read the impo r­
tant information about safety and heed the
WARNINGS i n this chapter .
Deployment of the Advanced Airbag System
and the activat ion of the safety be lt preten­
sione rs depend on t he dece le rat ion meas ured
by the c rash senso rs and regis tered by the
e lectronic control un it . Crash severity depends
on speed and dece leration as well as the mass
and stiffness of the vehicle o r object involved
in the crash. When the e
lectronic contro l unit registe rs a
low severity cras h and the safety belt is being
u sed, the airbag will not dep loy.
If the sa fety
belt is not being used, the first stage deploys,
followed by the second stage after a much lat­ er t ime in t he crash sequence.
If the electron ic contro l unit registers a crash
of medium severity, the first stage of the air­
bag deploys followed by the second stage at a
much later time in the crash sequence -re ­
gardless of whether the safety belt is be ing
u sed or not . In higher sever ity c rashes as reg­
i ste red by the elec tronic con tro l un it, bo th the
first and se con d stages dep loy almost at the
same t ime.
On the passeng er side, rega rdless of safety
belt use, t he a irbag w ill be tu rned off if the
we ight on the passenger seat is less th an the
amount programmed in the e lectronic control
u nit . The front airbag on the passenge r side
will a lso be turned off if one of the child safe ­
ty seats that has been certified under Federal
Motor Vehicle Safety Standard 208 has been
recogni zed on the seat . The
PASSENGER AIR

A WARNING
-You should perform brak ing maneuvers
for the purpose of cleaning the brake
system only if road cond it ions permit .
Other road users must not be put at r isk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transm iss ion into a lowe r
gear or lowe r driving range. Do not ride
the brakes or hold the pedal down too
long or too often . This cou ld cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the b rakes" by resting your
foot on the pedal when yo u do not intend
to brake . Th is may cause the brakes to
overheat, premature wear and increased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing throug h wa­
ter, driving in heavy rai n or after wash ing
the vehicle, the effect iveness of the
brakes can be reduced. In winter, ice can
accumulate on the brake pads, lini ngs,
discs and d rums. Carefully apply brakes
f or a test . B rakes wi ll dry and ice coat­
ings wi ll be cleaned
off after a few ca re ­
ful brake applications.
- Driv ing for an ex tended pe riod of time on
salt -covered roa ds without using your
brakes can also affect braking efficiency.
Clean
off accumulated salt coating from
brake discs and pads with a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you install a different spoiler, be sure the air
flow to the front brakes is not obstruct­
ed . Otherwise the brake system could
overheat reducing the eff ectiveness of
the ent ire brake system.
- Failure of one bra ke c ircuit will impair
the brak ing capability resulting in an in­
cr eased stopp ing distan ce. Avoid dr iv ing
the ve hicle and have it towed to the near­
est Aud i dea le r or q ualified workshop .
- Never le t the vehicle ro ll to a stop w ith
the engine shu t off.
Int ellig ent technolog y 145
-If the brake booster is not working, the
brake peda l must be pressed considera­
bly harder to make up for the lack of
booster assistance.
Electro-mechanical
power assist
The ele ctro-mechanical power assist helps
the driver when steering .
The degree of power assist is electronically
matched to veh icle speed.
The powe r steering system assists the driver
so that he can steer the vehicle with reduced
physical effort.
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be hard
to turn .
A WARNING
If the system develops a problem, you
must seek qualified professiona l assis­
tance.
(D Note
-
If there is an electronic malfunction, ser­
votronic
will still function like a conven­
tiona l powe r steering system, providing a
constant steering support force tha t is no
l onger proportionate to the vehicle speed.
This is most noticeable when t urning the
steering wheel at low speeds (for example
when parking), - more effort w ill be re­
quired than usual.
- Be aware of the different than usual
steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right
by an authori zed Aud i dea ler as soon as
possible.
- If a steering malfunction occurs, th is is
signa led w ith the
ls4 or .• indicator
lights and a warn ing tone, see. •
