Automatic transmission
Introduction
The automat ic transmission is controlled e lec­
tron ica lly. Power is transferred using a torque
converter.
The transm ission shifts up or down automat ically
depending on wh ich drive program is selected.
When a
mod erate driving s tyle is used, the
transmission selects the most e conomical d riving
mode. The t ransm iss ion upsh ifts at a lower RPM
and downshifts at a highe r RPM to imp rove fuel
efficiency.
The transm ission switches to a spor ty mode after
a kick-down or when the driver uses a
sp o rt y
driving style
c haracterized by quick accelerator
pedal movements, heavy acce leration, frequent
changes in speed and traveling at the maximum
speed.
If desired, the dr iver can also select the gears
manually (tiptronic mode)

General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­ my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trailer operation mode
c:> page 89, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use only a trailer hitch with a re­
movable ball mount. Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bolts remain securely fastened.
When you are not towing a trailer, remove the trailer hitch ball mount . This prevents the hitch
from causing damage should your vehicle be
struck from behind
£:=? .&, .
Trailer towing
Trailer brakes
If your trailer is equipped with a braking system,
check to be sure that it conforms to all regula­
tions.
T he trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety chains
Always use safety chains between your vehicle and the trailer.
Trailer lights
Trailer lights must meet all regulations. Be sure
to check with your Audi dealer for correct wiring,
switches and relays .
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear .
.,&. WARNING
-After removing the trailer hitch, do not store
it in your vehicle. In case of sudden braking,
the hitch could fly forward and injure you or
your passengers.

not properly wearing the restraints p rovided
by Audi.
Trailer towing
information
Important to know
-
Your ve hicle handles different ly when towing a
tra ile r because of the additiona l we ight and dif­
ferent weight distribution . Safety, performance
and economy wi ll greatly depend on how careful­
l y you load your trailer and operate your rig.
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic . Keep practicing until you have be­
come comp letely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires practice .
Backing up with a trailer generally requires steer­
ing action opposite to that when backing up your
vehicle without a trailer.
Trailer towing
Maintain a greater distance between your vehicle
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 normal turning radius.
When passing, remember that you cannot accel­
erate as fast as you normally wou ld because of
the added load. Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
c h anges.
(D Tips
-Do not tow a trailer during the break-in peri­
od of your ve hicle.
-If you tow a trailer, your Audi may require
more frequent maintenance due to the ex ­
tra load
¢ page 336 .
Parking on a slope
Do not park on a slope with a trailer. If it cannot
be avoided, do so only after doing the following:
When parking:
.,. App ly the foot brake.
.,. Have someone place chocks under both the ve­
hicle and the trailer wheels .
.,. With chocks in place, slowly release the brakes
until the wheel chocks absorb the load .
.,. Tur n the whee ls towards the curb .
.,. Apply the parking brake .
.,. Select the P selector lever posit ion.
When restarting after parking:
.. App ly the foot brake .
.. Start the engine .
.,. Select the D selector lever position.
.,. Release the parking brake and slowly pull out
and away from the wheel chocks.
.,. Stop and have someone retrieve the wheel
chocks .

Description
Applies to: vehicles with Audi adaptive cruise control
Fig . 1 03 Detect ion range
The adaptive c ruise co ntro l system is a comb ina­
tion of speed and d ist ance regula tion. It assists
the dr iver by bot h regula ting the speed and
maintaining a distance to the vehicle driving
ahead , within the limits of the system . If the sys­
tem detects and object ahead, adaptiv e cruis e
control can brake and acce lerate your vehicle.
Th is makes driving more comfortable both on
long stretches of highway and in stop-and-go
traffic .
What can adaptive crui se contr ol do?
The adaptive cruise contro l system uses video, ra ­
dar and ultraso und. Objects driving ahead can be
recogni zed up to 650 feet (200 m) away.
On open roads with no traffic , it functions like a
cru ise control system . T he stored speed is ma in­
tained. When approaching an object ahead, the
adapt ive cruise con trol system automatically
brakes to match that object's speed and then
maintains the stored d istance. As soon as the
sys tem does not detect a n object ahead, adaptive
cru ise con trol acce lera tes up to the stored speed .
In stop-and -go traff ic, adaptive cru ise control can
brake unt il the vehicle is s tat io nary and then be­
g in d riving aga in under certain conditions
