What c an adaptive cruise contr ol do ?
The adaptive cruise control works in conjunc ­
tion with a radar sensor installed in the front
of the vehicle¢
page 97 , fig. 96, which is sub­
ject to designated system limits ¢
page 99.
Stationary objects are d is regarded .
On open roads w ith no traff ic, adaptive cruise
control works like a regu lar cruise control sys- tern.
The stored speed is maintained . When
approaching a moving vehicle detected up
ahead, the adaptive cruise control system au ­
tomat ica lly s lows down to match that vehi­
cle's speed and then maintains the distance
that the driver previously stored . As soon as
the system does not detect a veh icle up
ahead, adaptive cru ise contro l accelerates
ba ck up to the stored speed.
Which fun ctions can be con trolled?
When you switch adapt ive cruise control on,
you can set the current speed as the "control
speed"

When dr iving, you can stop cruise contro l
¢
page 101 or change the speed ¢ page 101
at any time.
You can also set the distance to the object
ahead and set the adapt ive cru ise contro l driv­
ing program

Audi drive select Driving settings
Introduction
App lies to vehicles: w it h drive se lect
Audi drive select provides the possibility to ex­
perience different types of veh icle sett ings in
one vehicle. For instance, using the three
Comfort, Auto and Dynamic modes, the driv­
er can switch from a sporty to a comfortab le
driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehi ­
cle setup for
Individual* mode can be cus­
tomized by you. This makes it possib le to
combine settings such as a sporty engine tun­
ing with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury.
Description
Ap plies to vehicles: w it h drive se lect
The vehicle setup in each mode depends on
the vehicle's features. However, the engine,
automatic t ransmission* and steering are al­
ways involved.
.
Engine and automatic transmission*
Depending on the mode, the engine and the
automatic transmission respond quicker or in
a more ba lanced manner to acce lerator pedal
movements. In the sporty dynamic mode, the
automatic transmission shifts at higher R PMs.
Steering
The steering adapts in terms of steering effort
and steering ratios . Indirect steer ing that
moves easily, like the stee ring in comfort
mode, is best su ited to long dr ives on a high­
way. In contrast, dynamic mode prov ides
sporty, di rect steering .
The follow ing applies to vehicles with dynam ic
steer ing*: the stee ring ratio changes based on
ve hicl e speed in order to maintain optimum
Audi drive select 111
steering effort for the driver at all times. This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is more direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuveri ng the vehicle . At low and average
speeds, dynamic steering addit iona lly pro­
vides more responsive steering pe rformance.
Adaptive dampers*
The adaptive dampers* use sensors to record
i nformation regarding steering movements,
braking and acceleration operations by the
drive r, road surface, driving speed, and load.
T his makes it possible to adapt damp ing to
the driving situation virtually i n rea l time.
Audi drive select also makes it possible to sat­
isfy the desire for sporty s uspension (Dynam­
ic) and comfortable suspension (Comfort)
without giv ing up balanced tuning (Auto).
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
q page 189, the sport differential*
distributes the driving power to the rear axle
depending on the situation . The distribution
of power var ies depending on the mode se­
lected. The goal is a high level of agility and
ability to accelerate on curves . The ve hicle is
very respons ive to steering .
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise control
also responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner .
Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from subtle to sporty.
0) Tips
-In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynamic modes.

You can compensate for this by pressing
the brake pedal more firmly. This also applies later when new pads are instal­
led .
- 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 acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lowe r 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 c ircuit will impair
the braking capability resulting in an in­
creased stopping distance. Avoid driv ing
the vehicle and have it towed to the near- est authorized 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
pressed considerably harder to make up
for the lack of booster assistance.

The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the fir st 600 miles (1,000
kilometers ):
.,. Do not use full throttle.
... Do not drive at engine speeds that are more
than 2/3 of the max imum permitted RPM.
From 600 to 1,000 miles (1 ,000 to
1,500 kilometers):
.,. Speeds can gradually be increased to the
max imum pe rm iss ible road or eng ine speed .
During and after break-in per iod
... Do not rev the eng ine up to h igh speeds
when it is cold. Th is app lies whether the
transmission is in N (Neutral) or in gear.
After the break- in period
... Do not exceed max imum eng ine speed un­
der any circumstances .
... Upshift into the next higher gear
before
reaching the red area at the end of the tach­
ometer scale¢

198 Trailer towing
Trailer towing tips
Important to know
Your vehicle hand les different ly when tow ing
a trailer because of the addit ional weight and
different weight distribution . Safety, perform­
ance and economy wi ll greatly depend on how
carefully you load your trailer and operate
your rig.
Before you actually tow your trailer, practice
turning, stopp ing and backing up in an area
away from traffic. Keep practicing until you have become completely familiar with the way
your veh icle-trailer combination behaves and
responds.
Backing up is difficult and requires practice.
Backing up with a trai ler generally requires
steering action opposite to that when backing
up your vehicle without a trailer.
Maintain a greater distance between your ve­
hicle 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 ac­
celerate as fast as you normally would be­
cause of the added load. Make sure you have
enough room to pass . After passing, allow
plenty of room for your tra iler before chang­
in g lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a tra iler dur ing the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re­
quire more frequent maintenance due to
the extra load
q page 2 72.
Parking on a slope
Do not park on a slope with a trailer . If it can­
not be avoided, do so only after doing the fol­ lowing :
When parking:
.. App ly the foot brake.
.. Have someone place chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.. Tur n the wheels towards the curb.
.. App ly the parking b rake.
.. Place an automatic transmission* in P, re­
spectively a manual transmission in first or reverse gear.
When restarting after parking:
.. App ly the foot brake .
.. Start the engine.
.. Move the se lector lever to D/S, respectively
a manual transmission in first gear.
.. Release the parking brake and slow ly pu ll
out and away from the wheel chocks.
.. Stop and have someone retr ieve the wheel
chocks .
(D Tips
If you move the selector lever of the auto­
matic transmission* to P before applying
the parking brake and before blocking the
whee ls, you may have to use more force
lat er to move the lever out of the P posi­
tion.
