Before you move the se lector lever from the
P
position, you must always app ly the brake
pedal before and while depressing the button
in the handle of the selector lever.
A WARNING
- Unintended vehicle movement can cause
serious injury .
- When the se lector lever is in a d riving
position, the vehicle may creep, even at
idle speed. Therefore do not release
the parking brake or foot brake until
you are ready to move, because power
i s transmitted to the wheels as soon as
a driving position is engaged.
- Do not accelerate while selecting a
driv ing position. At this time the en­
gine must be at idle speed so that un­
due stress is not placed on the clutches
i n the transmiss io n.
- Remember: Even when stopped br iefly
with the automatic t ransmission in D/S
o r R, eng ine power is bei ng transmit­
ted to the wheels. Your veh icle cou ld
"creep" forward or backward. Whe n
stopped, keep the b rake pedal fully de ­
pressed and use the parking brake if
necessary to keep the vehicle from ro ll­
i ng.
- If the selector lever is un intent ionally
moved into N while you are driving, take
your foot off the accelerator peda l and
wait for the eng ine to retu rn to idle
speed before selecting a dr iv ing pos ition.
- Never sh ift into R or P when the vehicle is
in motion .
- Never get out of the driver's seat when
the eng ine is ru nning.

-If you must g et out of the vehicle, move
the selector lever securely into the P po­
sition and apply the parking brake f irmly.
-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
firmly set

When the vehicle is stationary or at speeds
below 3 mph (5 km/h), you must always apply
the footbrake before and while moving the
lever out of
N.
D/S - Normal position for driving forward
In the D/S position, the transmission can be
operated either in the normal D mode or in
the S sport mode . To select the S sport mode,
pull the selector lever back briefly. Pulling the
lever back again will select the normal D
mode. The instrument cluster display shows
the selected driving mode.
In the
normal mode D , the transmission auto­
matically selects the best gear ratio.
It de­
p ends on engine load, vehicle speed and the
dynamic control program (DRP).
Select the
sport mode S for sporty driving.
The vehicle makes full use of the engine's
power. Shifting is more noticeable when accel­
erating.
When the vehicle is stationary or at speeds
below 3 mph (5 km/h), you must always apply
the foot brake before and while moving the
lever to
D/S out of N .
In certain circumstances it may be advanta­
geous to temporarily switch to the manual
shift program to manually select gear ratios .,..

A time delay element prevents the selector
lever from locking when it is moved through
the
N posi tion (going from R to D/S ). 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 abo ut 3 mph (5 km/h) the
Automatic Shift Lock is automatically deacti­
vated in the
N position .
Interlock button
The lock button on the selecto r lever prevents
the lever from being accidentally shifted into
certain positions. Pressing this button deacti­
vates 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¢
fig. 114.
Kick-down
App lies to vehicles: wit h tiptro ni c
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 fea­
ture on slippery roads. Rapid acceleration
may cause the vehicle to skid .

110 Autom atic Tran smi ssi on
Dynamic shift program (DSP)
Appli es to vehicles: with tiptronic
The automatic transmission is electronically
controlled .
The transmission is self adapting and will au­
t oma tically
select the best shift program suit­
ed to the driving conditions and driving style .
The transmission will se lect one of the
econo ­
my programs when you drive at a steady
speed or a gradually changing speed without
heavy acceleration . This achieves optimum
fuel efficiency, with early upsh ifting and de­
layed downshifting.
The transmission will automatically select the
s po rty shift programs when you drive at high­
er speeds, or w ith heavy acceleration and fre­
quent ly changing speeds. Upshifts are de layed
to make f ull use of eng ine power. Downsh ift­
i ng takes p lace at higher engine speeds than
in the economy programs.
The se lection of the most suitable shift p ro­
gram is a cont inuous, automati c process. The
driver can also make the t ransmission switch
to a sporty prog ram by
quic kly pressing down
the gas pedal.
This causes the transmission to shift down to
a lower gear to achieve rap id acceleration, e.g.
for qu ickly passing another veh icle. You do not
need to press the gas peda l 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.
This keeps the transmission from shifting up
a nd down unnecessari ly on hills. The trans­
mission will shift down to a lower gear when
the driver presses the brake pedal on a down­
h ill gradient. This makes use of the braking ef­
fect of the eng ine without the need to shift
down manually .
Manual shift program
Applies to vehicles: wit h tiptronic
Using the manual shift program you can
manually select gears .

When accelerating, the transmission will au­
tomatica lly shift into the next gear before the
engine reaches its maximum RPM.
If you apply a light throttle whe n accelerat-
ing, tiptronic wi ll automatically shift from 1st
to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission wi ll stay in 1st gear .,.

until near maximum RPM is reached, or until
the driver shifts into 2nd gear.
I f yo u take your foot off the accelerator pedal
when dr iving 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 engine RPM. Auto ­
matic downshifting is interrupted as soon as
you apply the throttle again.
@ Tips
- When you shift into the next lower gear,
the transmission will downshift only
when there is no possibility of over-rev­
v ing the engine.
- When the kick-down comes on, the
transmission will shift down to a lower
gear, depending on vehicle and engine
speeds.
- tiptron ic is inoperative when the trans­
mission is in the fail-safe mode .
Steering wheel with tiptronic

WARNING
- You should perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit.
Other road users must not be put at risk -
you may cause an accident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
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
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing through wa­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned off after a few care­
ful 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
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 effectiveness of
the entire brake system.
- Failure of one brake circuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driving
the vehicle and have it towed to the near­
est 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, for
example when towing your vehicle, or
because the brake booster has somehow
been damaged, the brake pedal must be

carefu lly you load yo ur trailer and operate
your rig.
B efore you actua lly tow your trailer, practice
turning, stopping and backing up in a n area
away from traffic. Keep practicing until you
have become comp letely fam iliar with the way
your veh icle- trailer comb inat ion behaves and
responds .
Backing up is d ifficu lt and requires practice .
Backing up with a tra iler genera lly requires
steer ing action opposite to that when backing
up your vehicle without a trailer .
M aintain a g reater distance between your ve­
hi cle and the one in front of you. You will need
more room to stop. To compensate for the
trailer, you will need a larger than norma l
turn ing radius.
When passing, remember that yo u cannot ac ­
celerate as fast as you normally would be­
cause of the added load . Make s ure you have
e nough roo m to pass . After passing, allow
p lenty of room fo r your tra ile r befor e chang­

Parking on a slope
Do not park on a slope with a trailer. If i t can­
not be avoided, do so only after doing the fol ­
lowing:
When parking:
.. Apply the foot b rake .
.. Have someone place chocks under both the
vehicle and the trailer wheels.

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost always removed as
well. It is therefore essential to have a long­ lasting corrosion protection reapplied to all
surfaces, seams, joints and components in the
engine compartment .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
causing personal injury from the moving
wiper linkage .
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can sw itch
on suddenly -even when the ignition is
off.
- Do not wash, wax or dry the engine with
the engine running . Moving or hot parts
could injure you.
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
-Always read and heed all WARNINGS and
other information

236 Tires and wheels
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
Glossary of tire and loading terminology

means the maximum total loaded weight of
the vehicle.
Groove
means the space between two adjacent tread
ribs .
Load rating (code)
means the maximum load that a tire is rated
to carry for a given inflation pressure. Yo u
may not find this information on all tires be­
cause it is not required by law.
Maximum load rating
means the load rating for a tire at the maxi­
mum permissib le inflation pressure for that
tire.
