Adaptive Cruise Control
Speed and distance control system
Applies to vehic les : with Adaptive C ruise Cont rol
Description
The Adaptive Cruise Control driver assistance pr ogram is
a combined speed and distance control system .
Fig. 123 Fro nt
bu mper: Pos it io n of
r adar senso r
Adaptive Cruise Control can help make driving more re laxed and
less t iring, particula rly during long trips on interstates or other
highways that are generally straight .
Set ACC to maintain a constant, legal travel speed between 20 and
95 mph (30 -150 km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the vehicle ahead and ACC
w ill adjust your speed to maintain that distance .
Adaptive Cruise Contro l has technical limitations that you must
know, so please read this section carefully, understand how the
system works and use it proper ly at all times .
How does it work ?
You can operate the Adaptive Cruise Control using the lever on the
steering wheel column=> page 130, "How is the speed stored?" a nd
=> page 133, "How is the distance (time interval) set? ".

The distance at which the Adaptive Cruise Control follows a vehicle in front is determined by
time intervals. A time interval to a vehicle
in front is established and maintained. This produces a speed ­
dependen t interval. The higher the speed , the greater the safety
interval in feet (meters)
=> &..
For example, if the interval DISTANCE 3 is set, a vehicle in front is
followed at a
time interval of 1.8 seconds .
For a speed of
50 mph (80 km/h) this would be equivalent to a
distance of
131 feet (40 meters) to the vehicle in front.
The distances given here are nominal values. The vehicle speed may exceed or fall short of these target speeds, depending on the
driving situation and the driving style of the vehicle ahead.

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
q u ickly 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 orig inal 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 and down unneces ­
sarily on hills. The 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 .•

When accelerating, the transmission will automatica lly shift into
gears 1, 2, 3, 4 or 5 before the engine reaches its maximum RPM.
If you app ly a light throttle when accelerating, tiptronic ® will auto ­
matical ly shift from 1st to 2nd gear to save fuel. If you apply a heavy
throttle, the transmission w ill stay in 1st gear until near maximum
RPM is reached , or until the driver shifts into 2nd gear .
If you take your foot off the accelerator peda l when driving down a
steep inc line, tiptronic ® will downshi ft from the selected 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 throttle again.

General information
Your vehicle is equipped with a electronically controlled continu­
ously variable transmission (multitronic®l. Inside the multitronic ®
system, the gear ratios are not shi fted in finite steps as in a conven ­
tional automatic transmission, but rather
contin uously. As a result,
engine power is applied smoothly and comfortably, and better fuel
economy is achieved.
The transmission selects the appropriate gear ratio (upshifts and
downshifts) automatically based on set driving programs
=> page 165, "Dynamic shift program (DSP)".
You can also manually select a shift program (tiptronic®)
=> page 166.
You should note, that the multitronic transmission differs from a
conventiona l Automatic Transmission . In the multitronic transmis­
sion the engine power is transferred via a link -plate chain, rather
than by a conventional torque converter. The multitronic transmis­
sion greatly reduces vehicle "creep" when at a standstill and the
transmission is in

What impairs driving safety?
Safe driving is directly related to the condition of the
vehicle, the driver as well as the driver's ability to concen­
trate on the road without being distracted.
The driver is responsible for the safety of the vehicle and all
of its occupants. If your ability to drive is impaired, safety
risks for everybody in the vehicle increase and you also
become a hazard to everyone else on the road =>& .There ­
fore:
Do not let yourself be distracted by passengers or by
using a cellular telephone .
NEVER drive when your driving ability is impaired (by
medications, alcohol, drugs, etc.).
- Observe all traffic laws, rules of the road and speed limits
and plain common sense .
- ALWAYS adjust your speed to road, traffic and weather
conditions.
- Take frequent breaks on long trips. Do not drive for more
than two hours at a stretch.
- Do NOT drive when you are tired, under pressure or when
you are stressed .
& WARNING
Impaired driving safety increases the risk of serious personal
injury and death whenever a vehicle is being used. •

& WARNING (continued)
to help reduce the risk of personal injury if the driver's airbag
inflates.
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub . Holding the steering wheel the wrong way
can cause serious injuries to the hands, arms and head if the
driver's airbag deploys .
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli­
sion.
• Always sit in an upright position and never lean against or
place any part of your body too close to the area where the airbags
are located .
• Before driving, always adjust the front seats and head
restraints properly and make sure that all passengers are properly
restrained.
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle. • Never drive with the backrest reclined or tilted far back! The
farther the backrests are tilted back, the greater the risk of injury
due to incorrect positioning of the safety belt and improper
seating position.
• Children must always ride in child safety seats
=> page 238.
Special precautions apply when installing a child safety seat on
the front passenger seat
=> page 215. •

Proper seating position for the front
passenger
The proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the
seat for the front passenger to the following pos ition:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel =>
&.
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it
whenever the vehicle is moving.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but not lower
than eye level and so that it is as close to the back of your
head as possible =>
page 199.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=:>
page 209.
For detailed information on how to adjust the front passenger's
seat, see
=> page 80 .
& WARNING
Front seat passengers who are unbelted, out of position or too
close to the airbag can be seriously injured or killed by the airbag
as it unfolds. To help reduce the risk of serious personal injury : .,

& WARNING (continued )
• Always adjust the head restraint properly so that it can give
maximum protection . •
Proper adjustment of head restraints
Correctly adjusted head restraints are an important part
of your vehicle's occupant restraint system and can help
to reduce the risk of injuries in accident situations.
Fig . 197 Correctly
adjusted head restraint
viewed from the side
The head restraints must be correctly adjusted to achieve
the best protection.
- Adjust the head restraint so that the upper edge of the
restraint is level with the top of your head, but no lower
than eye level and so it is as close to the back of your
head as possible :::::,
page 199, fig. 197.
Adjusting head restraints => page 86.
Controls and equip­
ment Safety first Vehicle operation
& WARNING
Driving
without head restraints or with improperly adjusted head
restraints increases the risk of serious injuries in a collision. To
help reduce the risk of injury:
• Always drive with the head restraints in place and properly
adjusted .
• Every person in the vehicle must have a properly adjusted head
restraint .
• Always make sure each person in the vehicle properly adjusts
their head restraint. Each head restraint must be adjusted
according to occupants' size so that the upper edge is as even
with the top of the person's head, but no lower than eye level and
so it is as close to the back of to the head as possible .
• Never attempt to adjust head restraint while driving . If you
have driven off and must adjust the driver headrest for any reason ,
first stop the vehicle safely before attempting to adjust the head
restraint.
• Children must always be properly restrained in a child restraint
that is appropriate for their age and size =>
page 238. •
Examples of improper seating positions
The occupant restraint system can only reduce the risk of
injury if vehicle occupants are properly seated.
Improper seating positions can cause serious injury or
death. Safety belts can only work when they are properly
positioned on the body. Improper seating positions reduce
the effectiveness of safety belts and w ill even increase the
risk of injury and death by moving the safety belt to critical
areas of the body. Improper seating positions also increase
the risk of serious injury and death when an airbag deploys and strikes an occupant who is not in the proper seating ..,
