86 Transmission
-Unintended vehicle movement can cause
serious injury .
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running,
activate the parking brake and move the
selector lever to P .
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent the vehicle from "creeping", you
must keep your foot on the brake when
the engine is running and the selector
lever is in D/S or R or "tiptronic" mode is
selected.
- Do not press the accelerator pedal when
changing the selector lever position
while the vehicle is stationary and the
engine is running.
- Never shift into
R or P while driving.
- Before driving down a steep slope, re-
duce your speed and shift into a lower
gear with "tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases
braking distance or causes complete fail­
ure of the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it
in place with the brake pedal or parking
brake .
- Never hold the vehicle on an incline with
a slipping clutch . The clutch opens auto­
matically when it becomes too hot from
the overload . An indicator lamp
l'§J illu­
minates and a driver message appears
Q page 88 when the clutch is overload­
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
Q page 195. Otherwise, any increase in
engine speed may set the vehicle in mo- tion
, even with the parking brake ap­
plied.
@ Note
- When stopping on an incline, do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis­
sion to overheat and can damage it. Acti­
vate the parking brake or press the brake
pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en­
gine is stopped and the selector lever is
in N will damage the transmission be­
cause it is not lubricated under those cir­
cumstances.
(D Tips
For safety reasons, the parking brake is re­
leased automatically only when the driv­
er's safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
Hill descent control is activated when these ­
lector lever is in D/S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de ­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical
and technical limitations. It may st ill be nec­
essary to adjust the speed with the brakes.
Hill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
On vehicles with the cruise control system*
Q page 81 , hill descent control is also activat­
ed when the speed is set.
A WARNING -
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all

-Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system.
-All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment , cellular telephones and CB
radios, etc.) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­
shop.
- Never modify the front bumper or parts
of the vehicle body .
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­ backs that have not been specifically
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 air­
bag module must always be repaired
immediately by an authorized Audi
dealer.
- The airbag system can be activated only
once. After an airbag has inflated, it must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once. After an airbag has been deployed,
it must be replaced with new replace-

cially for your Audi model version . Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only. Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD.
- In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten ­
sioners might be classified as Perchlorate
Material -special handling may apply, see
www .dtsc.ca.gov/hazardouswaste/per-
ch lorate. When the vehicle or parts of the
restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
dealer is familiar with these requirements
and we recommend that you have your
dealer perform this service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi ,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for

The weight ranges fo r the ind ividual types,

NHTSA has specified in the Safety Standard
together with the weight ranges of typical in­
fants and typical 1 year-o ld child have been
stored in the control unit of the Advanced A ir­
bag System. When a child restraint is being
used on the front passenger seat with a typi ­
cal 1 year-old ch ild, the Advanced Airbag Sys­
tem compa res the we ight measured by the
weight sensing mat with the informat io n sto r­
ed i n the ele ct ron ic cont ro l uni t.
The electron ic control unit also registers the
tension on the front passenge r safety belt .
The tens io n on the safety be lt fo r the front
passenger seat will be d iffe ren t for an ad ult
who is prope rly using the safety belt as com­
pared to the tension on the be lt whe n it is
used to attach a chi ld restraint to the seat.
The sensor below the latch for the safety be lt
for the front seat passenger meas ures the
tension on the be lt. The input from this sen­
sor is then used with the we ight to "decide",
whether there is a ch ild restraint w ith a typ ical
1 year-o ld child o n the front passenger seat
and whe ther or not the ai rbag must be tu rned
off.
Child restraints and Advanced Airbags
Regardless o f the child restraint t hat you use,
make sure that it has been ce rtified to meet
United States Federal Motor Vehicle Safety
Standards and has been certified by its manu­
f acturer for use with a n airbag. Always be sure
that the child restraint is properly instal led at
one of the rear seat ing pos itions .
If in excep­
tional c ircumstances you must use it on the
fro nt passenger sea t, caref ully read all of the
i n format ion on c hild safety and Advanced A ir­
bags and heed a ll of the app licab le WAR N­
I NGS . Ma ke certain that the child restraint is
correctly recognized by the weig ht-sensing
mat inside the front passenger seat, that the
fro nt passenger airbag is turned off and that the a
irbag sta tus is always cor rect ly signa led
by the
PASSENGER AIR BAG OFF light .
Many types and models of child res traints
h ave been available over the yea rs, new mod­
els are introduced regu larly incorporating new
and improved designs and o lde r mode ls are
ta ken out o f product ion . Ch ild restra ints are
not standard iz ed . Child restraints of the same
type typically have different weights and sizes
and different 'footpr ints,' the size and shape
of the bottom of the ch ild restra int that sits
on the seat, when they are insta lled on a vehi­

distance detected to the vehicle ahead is too
smal l.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills .
Electronic differential lock (EDL )
The EDL brakes wheels that are spinn ing and
transfers the d rive powe r to the other wheels.
This f unct ion is available up to abo ut 60 mph
(100 km/h) .
In extreme cases, ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll switch on aga in a u­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steeri ng*, ESC also
helps to stabilize the stee ring in critical s itua­
tions.
Select ive wheel torque control
Selective whee l torque control is used when
driving on curves . The front wheel on the in­
side of the curve or both wheels on the inside
of the curve are braked selective ly as needed.
This a llows mo re prec ise d riving in curves. The
appl icable system may no t activate when d riv­
i ng in wet or snowy condi tions.
A WARNING
- The ESC and its integrated systems can ­
not overcome the laws of physics. This is especia
lly important on slippery o r wet
roads. If the systems begin acting to sta­
bilize your veh icle, you should immedi­
ately change your speed to match the
road and traffic cond itions. Do not let
the increased safety provided by these
systems tempt you to take risks. Do ing
so will in crease the r is k of a loss of vehi­
cle control, collision and serious person al
in juries.
- Always adap t your speed to road, traffi c
and weather conditions . The risk of los ­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when dr iv ing too close to vehicles up
ahead. The ESC and its integrated sys­
tems cannot a lways p revent collisions -
there is still a risk of acc idents!
- Always accelerate with special care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
T he drive w heels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to re duce the risk of loss of ve ­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
a ll four wheels are equipped wi th iden ti­
c al tires. D ifferen t tire sizes can lead to a
reduction in engine powe r.

Braking
What affects braking efficiency?
New brake pad s
Du ring the first 2 50 miles (400 k m), new
b ra ke pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
The break-in period can be considerably lon­
ger for vehicles with ceramic brake rotors*.
You can compensate for this slightly reduced br aking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
b reak-in per iod.
Operating conditions and d riving h abits
The brakes on today's automobi les are st ill
subject to wear, depend ing largely on operat­
ing conditions and dr iv ing habits ¢.&. . On
vehicles that are e ithe r dr iven mostly in stop­
and-go city traffic o r are driven ha rd, the
b rake pads should be checked by you r aut hor­
iz ed A udi de aler more often than specified in
the
Warrant y & Maintenan ce booklet . Fail ure
to have your b ra ke pads inspected can resu lt
in red uced brake performance.
On steep slopes, yo u sh ou ld use t he b ra ki ng
effect of the eng ine. Th is w ay, you preven t un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not ho ld the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
N oises may occur when braking depending on
the speed, braking fo rce and outside condi­
tions s uch as temperature a nd h umidity.
Due to the na ture of the mate rials used i n ce­
ramic brake rotors*, noises may become more
apparent at low speeds.
Effect of water and road salt
I n ce rtain situat ions, for exampl e after d riving
throug h wate r, in heavy ra in, after overn igh t
conde nsation or afte r washi ng your c ar, the
b ra ki ng effect can be reduced by moisture or
ice on the bra ke rotors and b rake pads. The brakes must be dr
ied first with a few careful
brake applications .
At highe r speeds and with the winds hield wip­
ers t urned on, the b ra ke pads press against
the b rake roto rs fo r a short amount o f time .
This occurs at regular intervals without the drive r not icing and p rov ides for better brake
response time under wet conditions.
The effectiveness of the brakes can be red uced
whe n the vehicle is driven on a sa lt -covered
road and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap­
plicat ions of the bra ke
¢ .&. .
D ue to the ir s urface characteristics, ceramic
brake rotors* absorb moisture in such condi­
tions . T his can cause a temporary reduction in
braking force compared to dry brakes . You can
compensate for th is by pressi ng the brake
p eda l harde r.
Corrosion
There may be a tende ncy for dirt to build up
on the brake pads and corros ion to form on
the d iscs if the car is not driven regu larly or
only for short trips w it h litt le use of the
brakes .
If the brakes are not used frequently, or if cor­
ros io n has formed on the discs, it is adv isable
to clean off the pads and discs by braking
firmly a few times from a moderately h igh
speed ¢.&. .
Faults in the brake system
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ir cuits may have fa iled
c::> .&. .
Low brake fluid level
Malfunctions can occur in the brake system if
t h e brake fluid level is too low. The brake flu id
level is monitored electro nically .
Brake boo ster
The brake booster increases the pressure that
yo u generate with the brake peda l. It works
on ly when the engine is running
