• These approved roof racks are the basis for a complete roof rack
system . Additional attachments for the basic roof rack are necessary
to safely transport luggage, bicycles, surf boards, skis or small boats .
All necessary hardware for these systems is ava ilable at your autho ­
rized Audi dealer .
• We recommend tha t you keep the installation instructions for
your roof rack system together with your Owner's literature in the
vehicle.
When should the roof rack be removed?
• Before going through an automat ic car wash (it is best to ask the
car wash operator fo r advice)
• When not in use, to reduce fuel consumpt ion, wind nois e and to
guard against theft.
& WARNING
• Use of an unapproved roof rack or incorrect mounting of an
approved roof rack can cause the roof rack or the items attached
to it to fall off the roof onto the road.
• Objects falling from the roof of a vehicle can cause a crash and
personal injury.
• Only mount the system between the markings shown in
=> fig. 98.
• The roof rack system must be installed exactly according to the
instructions provided.
0 Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or mounting structures not approved by
Audi for your vehicle . The same applies to damage resulting from
incorrect roof rack installat ion .
• Always check the roof rack mountings and hardware before each
trip and dur ing a trip to make sure everything is sec urely tightened . If

necessary, ret ighten the mountings and check the entire system from
time to time.
• After mounting a roof rack system, or when you transport objects
on the roof of your veh icle, the height of the vehicle is naturally
increased. Be careful when driving under low bridges or in parking
garages for example. This could cause damage to the load and even
the vehicle itself . •
Mounting Locations
Safe installation of a roof rack requires that the rack
supports are mounted between the small arrows marked
inside the door frames on all four doors.

Seats and storage Loading the roof rack
Always dis tribute loads evenly . Make sure anything on
the roof rack is securely tied do wn.
- Always distribute the loads on the roof rack evenly .
- Always attach items to t he roof rac k securely before you
drive
off .
The maximum permissible roof weight is 220 lb (100 kg ). The roof
we igh t is made up of the weight of the roof rack system and the
we ight of the object be ing transported.
When using a roof rack system which has a lower load ca rrying
capac ity, you must not use up the total maxim um permissible load
carrying capacity specified above . Instead, you shou ld load the roof
ra ck system only to the maximum capacity specified by the manufac­
turer of the roof rack system.
& WARNING
Weak, damaged or improper straps used to secure items to the
roof rack can fail during hard braking or in a collision and cause
seriou s personal injury.
• Make sure the roof rack is installed ex actly as specified above
~ page 93 .
• Always use suitable mounting straps for se curing items to the
roof rack to help prevent items from shifting or flying forward.
• Items on the roof rack must always be se curely mounted.
• The use of a roof rack can negatively affect the way a vehicle
handles . Ca rgo that is large , heavy, bulky , long o r flat will ha ve a
greater negative influence on the vehicle' s aerodyn amics, center
of gra vity and ove rall handling. Alw ays drive slowly, a void sudden
braking and maneuvers when tran sporting cargo on th e roof of
your veh icle.
& WARNING (contin u ed )
• Never e xceed the maximum permi ssible load carrying capacity
of the roof of your vehicle, the permi ssible a xle weights and the
permissible total weight of your vehicle~

ECON
The ECON mode helps to save fuel .
The air conditioning is turned off in ECON mode. "ECON" means
" E conomy". By switching off the air conditioning (compressor), you
save fuel.
Please note that vehicle interior temperature cannot be lower than
the outside temperature in the ECON mode. The air is not cooled or dehumidified .
If the vehicle inter ior becomes too hot or if the windows fog up, ECON
mode should be turned off. As soon as the
( AUTO] button in the air
conditioning controls is pressed, the system automatically leaves the
ECON mode, and the air conditioning compressor is turned on
again. •
Automatic recirculation mode
An air quality sensor detects increased concentrations of
pollutants in the outside air and automatically switches
to recirculation mode .
We recommend that you always keep automat ic air recirculat ion ON
to prevent polluted outside air from entering the vehicle interior.
If the
air quality sensor located in the air conditioning system detects
polluted outside air, the sensor decides whether the air pollution can
be reduced by the facto ry-insta lled pollutant fi lter or whe ther it is
necessary to switch to air recirculation. With heavy concentrations of
pollutants, the air conditioning system is switched a utomat ically to
recirculation mode and the supply of outside air is blocked . As soon .,.

Automatic selector lever lock
The se lector lever is locked in the P and N positions when the ignition
is turned on. To move the lever from these posit ions 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 foot brake while selecting gear
A time delay element prevents the selector lever from lock ing 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 (Neutra l) for
more than approximately
l second, w ithout the brake pedal being
pressed.
At speeds above about 3 mph (5 km/h) the Automat ic Shift Lock is
automatically deactivated in the
N position.
Interlock button
The lock button o n the selector lever prevents the lever from being
accidentally shifted into certain 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 pos itions are
highlighted in the illustration ~
page 156, fig. 170.
Ignition key safety interlock
The key cannot be removed from the ignition un less 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.•
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 cont
inue 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. •
Dynamic shift program (DSP)
The automatic transmission is electronically controlled.
The transmission is self adapting and will automatically select the
best sh ift p rogram su ited to the driv ing cond it ions 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 ach ieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
Th e transmission will automatically select the
sporty shift programs
when you dr ive at higher speeds, or w ith 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 select ion of the most suitable shift program is a cont inuous,
automatic p rocess. The driver can also make the transmission switch
t o a spo rty program by
quickly pressing down the gas pedal.
Th is causes the transmission to shift down to a lower gear to achieve
rap id acceleration, e.g . for quickly passing another vehicle. Yo u 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 uph ill and downhill gradients.
Th is prevents the transmission from upshifting and downshifting
unnecessari ly on hills. The transmission will shift down to a lower _,.

To downshift
-Push the lever to the minus position Q.
When accelerating, the transmission will automatically shift into
gears 1, 2, 3, 4 or 5 before the engine reaches its maximum RPM .
I f you apply a light throttle when acce lerating, t iptronic ® will auto­
matically 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 unt il the dr iver shifts into 2nd gear .
I f you take your foot off the accelerator pedal when driving down a
steep incline, tiptronic ® will downsh ift from the se lected gear into
the next lower gear until it reaches 1st gear , based on road speed and
engine RPM. Automatic downshifting is interrupted as soon as you
apply the th rottle again.
lI] Tips
• When you shift into the next lower gear, the transmission will
downshif t only when there is no possibility of over- rewing the
eng ine.
• When the kickdown comes on, the transmission will sh ift down to
a lower gear, depending on vehicle and eng ine speeds.
• Tiptronic ® is inoperative when the transmission is in the fail-safe
mode. •
