Automatic selector lever lock
The selector lever is locked in the P and N positions when the ignition
is turned on . To move the lever from these positions the driver must
depress the brake pedal. As a reminder to the driver, the following
warning appears in the instrument cluster display when the selector
is in
P and N:
When stationary apply footbrake while selecting gear
A time delay element prevents the selector lever from locking when
it is moved through the
N position (going from R to D). The locking
element will lock the selector lever if the lever is left in N (Neutral) for
more than approximately 1 second, without the brake pedal being
pressed .
At speeds above about 3 mph (5 km/h) the Automatic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button on the selector lever prevents the lever from being
accidentally shifted into ce rtain positions. Pressing this button deac­
tivates the selector lever lock. Depending on the direction of the
shift, the selector lever locks at different positions . The positions are
highlighted in the illustration ~
page 153, fig. 147.
Ignition key safety interlock
The key cannot be removed from the ignition unless the selector lever
is in the
P park position . When the ignition key is removed, the
selector lever will be locked in the
P position. •
Applies to vehicle s: with au toma tic tr ansm is si on
Kick-down
The kick-down feature allows the vehicle to generate
maximum acceleration.
When you press the accelerator pedal beyond the resistance point
that is reached at full throttle, the transmission will select a lower
gear ratio based on vehicle speed and engine RPM . The engine RPM will be controlled to produce maximum vehicle acceleration as
long
as you continue to press the accelerator pedal beyond this resistance
point .
& WARNING
Be careful when using the kick-down feature on slippery roads.
Rapid acceleration may cause the vehicle to skid. •
Applies to ve hicles : with automatic t ransm iss ion
Dynamic shift program (DSP)
The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best shift program suited to the driving conditions and driving style .
The transmission will select one of the
economy programs when you
drive at a steady speed or a gradually changing speed without heavy
acceleration . This achieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
The transmission will automatically select the
sporty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds. Upshifts are delayed to make full use of
engine power . Downshifting takes place at higher engine speeds than
in the economy programs.
The selection of the most suitable shift program is a continuous,
automatic process . The driver can also make the transmission switch
to a sporty program by
quickly pressing down the gas pedal.
This causes the transmission to shift down to a lower gear to achieve rapid acceleration, e.g. for quickly passing another vehicle. You do
not need to press the gas pedal into the kick -down range. After the
transmission has upshifted, the original program is selected
according to your driving style.
An additional shift program allows the automatic transmission to
select the proper gear for uphill and downhill gradients.

Transmission Ill _______________ ___.
This keeps the transmission from shifting up and down unnecessarily
on hills . Th e transmission will shift down to a lower gear when the
driver presses the brake pedal on a downhill gradient . This makes use
of the braking effect of the engine without the need to shift down
manually .•

Switching to manual shift program
-Push the selector lever to the right from D. As soon as the
transmission has switched over, the selected gear appears
in the display.
To upshift
- Push the selector lever forward to the plus position 0
~ fig. 148.
To downshift
- Push the lever to the minus position Q.
When accelerating, the transmission will automat ica lly shift into the
next gear before the engine reaches its maximum RPM.
If you apply a light throttle when accelerating, tiptr onic will automat­
ically shift from 1st to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission will stay in 1st gear until near maximum
RPM is reached, or until the dr iver sh ifts i nto 2nd gear.
If you take your foot off the accelerator pedal when driving down a
steep incline , tiptronic will downshift from the selected gear into the
next lower gear until it reaches 1st gear , based on road speed and
eng ine RPM. Automatic downshifting is interrupted as soon as you
apply the throttle again.
[ i ] Tips
• When you shif t into the next lower gear, the transmission will
downshift on ly when there is no possibility of over-revving the
engine.
• When the kick-down comes on, the transmission will shift down to
a lower gear, depending on vehicle and engine speeds.
• tiptronic is inoperative when the transmission is in the fail-safe
mode. •

is being used. •
Driver and passenger side footwell
Applies to veh icles: w ith knee air b ags
Important safety instructions
& WARNING
Always make sure that the knee airbag can inflate without inter·
ference. Objects between yourself and the airbag can increase the
risk of injury in an accident by interfering with the way the airbag
deploys or by being pushed into you as the airbag deploys.
• No persons (children) or animals should ride in the footwell in
front of the passenger seat. If the airbag deploys, this can result in serious or fatal injuries.
• No objects of any kind should be carried in the footwell area in
front of the driver's or passenger's seat. Bulky objects (shopping bags, for example) can hamper or prevent proper deployment of
the airbag. Small objects can be thrown through the vehicle if the
airbag deploys and injure you or your passengers. •
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 freely without interference and that
nothing prevents them from returning to their original positions .
Only use floor mats that leave the pedal area free and can be secured
with floor mat fasteners.
If a brake circuit fails, increased brake pedal travel is required to bring
the vehicle to a full s top.
& WARNING
Pedals that cannot move freely can cause loss of vehicle control
and increase the risk of serious injury .
• Never place any objects in the driver's footwell. An object could
get into the pedal area and interfere with pedal function. In case
of sudden braking or an accident, you would not be able to brake
or accelerate!
• 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 attached to
the floor mat fasteners and do not interfere with the free
movement of the pedals.
- Make sure that the floor mats are properly secured and
cannot move and interfere with the pedals~& .

Driving Safely ---------------------" ~'----
Use only floor mats that leave the pedal area unobstructed and that
are firmly secured so that they cannot slip out of position . You can
obtain suitable floor mats from your authorized Audi dealer.
Floor mat fasteners are installed in your Audi.
Floor mats used in your vehicle must be attached to these fasteners.
Properly securing the floor mats will prevent them from sliding into
positions that could interfere with the pedals or impair safe opera­
tion of your vehicle in other ways .
& WARNING
Pedals that cannot move freely can result in a loss of vehicle
control and increase the risk of serious personal injury.
• Always make sure that floor mats are properly secured.
• Never place or install floor mats or other floor coverings in the
vehicle that cannot be properly secured in place to prevent them
from slipping and interfering with the pedals or the ability to
control the vehicle.
• Never place or install floor mats or other floor coverings on top
of already installed floor mats. Additional floor mats and other
coverings will reduce the size of the pedal area and interfere with
the pedals.
• Always properly reinstall and secure floor mats that have been
taken out for cleaning.
• Always make sure that objects cannot fall into the driver foot­
well while the vehicle is moving. Objects can become trapped under the brake pedal and accelerator pedal causing a loss of
vehicle control. •

The system operates across the entire speed range in combination
w ith the ABS sys tem. If the A nti-L o ck Brak e System (A BS) mal fun c­
tions, the ESP will also shut down.
How the system works
The Anti-Lock Brake System (ABS), Elect ronic D ifferential Lock (EDL)
and the Anti-Slip Regul ation System (AS R) are in teg rated in the e lec ­
tronic stab ilizat ion program . In addition to the data prov ided by
th ese fun ctions, the ESP control unit re quires addi tional meas ure ­
ment data provided by hig h pe rformance senso rs . The ro tat ional
speed of the vehicle about its vertical axis, veh icle acceleration in the
fore-and-a ft and lateral d irect ions, the brake pressure , a nd the
steerin g ang le are all measured .

the problem.
Th e ve hicle is t hen stab ilized by the fo rces acting on the whee l during

Vehicle care Do-it-yourself service Technical data

Intelligent t echnology
'-----------------------------------------------
Electronic differential lock (EDL)
The elec tronic differen tial lock monitors the rotational
speed of the drive wheels.
G en era l not es
The electronic differentia l lock (EDL) helps the ca r to sta rt moving,
accelerate and climb a gradient on surfaces provid ing poor or almost
no grip . W ithout ED L, this would be d iff icu lt, if not impossible.
How the sy stem works
The EDL operates automatically. It mo nitors the rota tional speed of
wheels with the help of the ABS sensors~
page 241. If a not iceab le
slip is detected at the wheels (e.g . on slippery g round on one side),
the spinn ing wheels are braked and power is transferred to the other
wheels . This is done up to a speed of about 60 mph (100 km/h).
No ises from the brake system signal that wheel sp in is being
controlled.
Driv ing off
When d riving off, always be s ure to keep road conditions in mind as
you accelerate. If one drive wheel spins because it is on a surface with
less grip, apply
plenty of throttle until the car starts to move.
O verheating of bra kes
To prevent the disc b rake of the bra ked wheel from ove rhea ting if
subjected to excessive loads on this wheel, the EDL cuts out tempo­
ra rily. The vehicle remains operat io nal and be haves in the same way
as a veh icle without EDL.
As soon as the brake has coo led down, EDL switches on again auto ­
matically.
& WARNING
• When ac ce le rating on s lippery surfa ce s, su ch as on ic e or snow,
alwa ys be ca reful when depre ssing the accele rator pedal. Even
& W ARNING (continue d)
with the EDL working , the dri ve wheels c an spin and reduce your
ability to contr ol your car . Ri sk of cra sh!
• The inc reased s afety afforded by E DL does not me an that you
can take safety ri sks. Alwa ys adapt your d rivin g style to the r oad
conditions and t raffic situation .
[ i ] Tips
If a fau lt occurs in the ABS, the EDL is also not funct ion ing. This is
ind ic a ted by the ABS warn ing light ~
page 17. •
Anti-Slip Regulation System (ASR)
The Anti-Slip Regulation System prevents the driven
wheels from spinning when the car is accelerating.
General notes
The Anti-Sl ip Regu lation System (ASR) is integrated in the electronic
stabiliza tion prog ram ( ESP) . When the ve hicle s tarts up and acceler­
ates, the wheels are prevented from sp inning by adjusting the engine
powe r to match the amount of g rip available from the road surface .
How the system works
ASR performs au toma tic a lly, i.e. witho ut the dr ive r's intervent ion.
With the aid of the ABS sensors~
page 241, ASR monitors the speed
of the driven wheels. If the whee ls start to spi n, eng ine torq ue is
reduced automatically unti l the tires find enough grip to lock onto
t he road s urface . The system is active across the en tire spee d range.
Th e ASR works in con ju nction with the ABS .
If a malfunction shou ld
occur in the ABS, the ASR wi ll also be out of action.
Act ivating
T he ESP is automatica lly activated when the engine is started and it
performs a self-test . You can act ivate a deact ivated ASR if required by _,,

Intelligent technology
--------------------------------------------------' '----'----
pressing the=> page 236, fig. 198 button. When it is activated, the
message
ESP/ASR on appears briefly in the display.
Deactivating
You can deactivate the ASR if req uired by press ing the button (for less
than 3 seconds) =>
page 236, fig. 198. With the ASR deactivated, the
ESP check light comes on, see=>
page 15. The message ASR off
appears in the display as well. The ASR can be deactivated at any
speed.
The ASR should normally be activated all the time . Only in certain
exceptional situations when some slip is desirable does it make sense
to deactivate the ASR. Examp les:
• when driving with tire chains
• when driving in deep snow or on loose ground and
• when rocking the vehicle loose after it has become stuck .
When the abnormal situation is over, you sho uld activate the ASR
again.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
(I) Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tir es . Any differences in rolling radius of the tir es can
cause the system to reduce eng ine power when this is not desired .

Braking
General information
What
affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending la rgely on ope rating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop-and-go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte ­
nance booklet.
Failure to have your b rake pads inspected can result
in reduced brake performance .
On steep slopes, you should use the braking effect of the engine. This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when b rak ing depending on the speed, braking
force and outside cond itions such as temperatu re and humid ity.
Moisture or road salt
If you are driving faster than 31 mph (50 km/h) and the windshield
wipers are on, the brake pads will briefly touch the brake discs in
regula r interva ls so as to improve reaction time when braking on wet
surfaces. You, the driver, will not not ice anything.
Under certain condit ions, for example, when driving through water or
very heavy rai n, or even after washing your vehicle, the braking effect
can be reduced due to moisture (o r in free zing conditions ice) on the
bra ke pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings.
Th e effectiveness of the brakes can be reduced when the vehicle is
dr iven on a salt-covered road and the brakes are not used. H ere too,
you should clean off accumu lated salt coating from brake discs and
pads with a few careful applications of the brake=>&,.
