Adaptive cruise control Speed and distance
control system
Description
Applies to vehicles: with adaptive cruise cont rol
The adaptive cruise control driver assistance
program is a combined speed and distance
control system .
Fig . 126 Front bu mper: Pos itio n of r adar sen sor (not
vi sibl e from out side)
Adapt ive cruise control can he lp ma ke driv ing
more relaxed and less tiring , particularly dur­
i n g long trips on interstates or other hig hways
that are genera lly st raight. The system can al­
so ass ist in stop and go traffic .
The adaptive cruise co ntrol works within a
speed range be tween 0 and 95 mph (150 km/
h). Set ACC to maintain a constant , legal trav ­
el speed between 20 and 95 mph (30 -150
km/h) that is appropriate for prevailing traffic
conditions. Select a following distance to the
veh icle ahead and ACC will adjust your speed
to maintain that d istance down to a stop . At a
speed below 20 mph (30 km/h), the min imum
speed setting of 20 mph (30 km/h) will be se­ l ected automati ca lly.
Adaptive cruise control has technical limita­
tions that you must know, so p lease read th is
section carefully , understand how the system
wo rks and use it properly at a ll times.
How does it work?
You can operate the adaptive cruise control
using the lever on the steering wheel column

A WARNING
Imp roper use of the adaptive cruise con­
trol can cause collisions, other accidents
and serious personal injury.
- Always remember that the adaptive cru ise contro l has limits -it will not slow
the vehicle down or ma inta in the set d is ­
tance when you dr ive towards an obsta­
cle or someth ing o n or nea r the road that
is not movi ng, such as ve hicles stopped
in a tra ffic jam, a sta lled or d is ab led vehi­
cle.
- Always remembe r that the adaptive
cru ise con tro l canno t detect a vehi cle
that is driving towards yo u in your traffic
lane and that it cannot detect narrow
vehicles s uch as motorcycles and bicy­
cles.
- Never drive at speeds that are too fast
for traffic, road and weather conditions.
- Never follow a vehicle so closely that yo u
cannot stop your vehicle safely. The
adaptive cruise control cannot s low or
brake the vehicle safely when you follow
another vehicle too close ly. Always re­
membe r that the adaptive cruise control
has a braking powe r th at is o nly about
30% of the veh icle 's maxim um braking
ab ility. The a uto mat ic bra kin g f unction
canno t bring the veh icle to a s udden or
emergency stop . Always be p repared to

~ Always keep both feet in the footwell so
that you are in control of the vehicle at all
times.
For detailed information on how to adjust the
driver's seat, see
¢ page 72.
A WARNING
Drivers who are unbelted, out of position
or too close to the airbag can be seriously
injured by an airbag as it unfolds. To help
reduce the risk of serious personal injury:
- Always adjust the driver's seat and the
steering wheel so that there are at least
10 inches (25 cm) between your breast­
bone and the steering wheel.
- Always hold the steering wheel on the
outside of the steering wheel rim with
your hands at the 9 o'clock and 3 o'clock positions to help reduce the risk of per­
sonal 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. Hold­
ing the steering wheel the wrong way
can cause serious injuries to the hands,
arms and head if the driver's airbag de­
ploys.
- Pointing the steering wheel toward your
face decreases the ability of the supple­
mental driver's airbag to protect you in a
collision .
- Always sit in an upright position and nev­
er lean against or place any part of your
body too close to the area where the air ­
bags are located.
- Before driving, always adjust the front
seats and head restraints properly and
make sure that all passengers are prop­
erly restrained.
- Never adjust the seats while the vehicle
is moving . Your seat may move unexpect­
edly and you could lose control of the ve­
hicle.
- Never drive with the backrest reclined or
tilted far back! The farther the backrests
are tilted back, the greater the risk of in-
Driving Safely 167
jury due to incorrect positioning of the
safety belt and improper seating posi­
tion .
- Children must always ride in child safety
seats ¢
page 205. Special precautions
apply when installing a child safety seat
on the front passenger seat¢
page 184 .
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 recom ­
mend that you adjust the seat for the front
passenger to the following position :
~ 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 the upper edge
is as even as possible with the top of your
head. If that is not possible , try to adjust
the head restraint so that it is as close to
this position as possible¢
page 168.
~ Keep both feet flat on the floor in front of
the front passenger seat .
~ Fasten and wear safety bel ts correct­
ly ¢
page 179 .
For detailed information on how to adjust the
front passenger 's seat, see ¢
page 71.
A WARNING ,_
Front seat passengers who are unbelted,
out of position or too close to the airbag
can be seriously injured or killed by the air­
bag as it unfolds. To help reduce the risk of
serious personal injury:
- Passengers must always sit in an upright
position and never lean against or place
any part of their body too close to the
area where the airbags are located.
- Passengers who are unbelted, out of po­
sition or too close to the airbag can be
seriously injured by an airbag as it

What happens to occupants not wearing
safety belts?
In crashes unbelted occupants cannot stop themselves from flying forward and being in­
jured or killed. Always wear your safety belts!
Fig. 201 A driver not wearing a safety belt is violently
thrown forward
Fig. 202 A rear p assenger not wearin g a safety belt
will fly forwar d an d st rike the driver
Unbelted occupants are not able to resist the
tremendous forces of impact by holding tight
or brac ing themselves. W ithout the benefit of
safety restraint systems, the unrestrained oc­
cupant will slam vio lent ly into the steering
wheel, instrument panel, windshield , or what­
ever else is in the way ¢
fig. 201. This impact
with the vehicle interior has all the energy
they had just before the crash.
Never rely on airbags alone for protection.
Even when they deploy, airbags provide only
additional protection. Airbags are not sup­ posed to deploy in all kinds of accidents. Al­
though your Audi is equipped with airbags, all
vehicle occupants, including the driver , must
wear safety belts correctly in order to mini­
mize the risk of severe injury or death in a
crash.
Remember too, that airbags will deploy only
once and that your safety belts are always
Safety belts 177
there to offer protection in those accidents in
which airbags are not supposed to deploy or
when they have already deployed. Unbelted
occupants can a lso be thrown out of the vehi­
cle where even more severe or fatal injuries
can occur .
It is also important for the rear passengers to
wear safety belts correctly . Unbelted passen­
gers in the rear seats endanger not only them­
selves but also the driver and other passen ­
gers ¢
fig. 202. In a frontal coll ision they will
be thrown forward violently, where they can
hit and injure the driver and/or front seat pas­
senger.
Safety belts protect
People think it's possible to use the hands to
brace the body in a minor collision. It's simply
not true!
Fig. 203 D river is correctly rest ra in ed in a sudde n brak­
ing maneuver
Safety belts used properly can make a big dif­
ference. Safety belts help to keep passengers
in their seats, gradua lly reduce energy levels
applied to the body in an accident, and help
prevent the uncontrolled movement that can
cause serious injuries. In addition, safety belts
reduce the danger of being thrown out of the
vehicle.
Safety belts attach passengers to the car and
give them the benefit of being slowed down
more gently or "softly" through the "give" in
the safety belts, crush zones and other safety
features engineered into today's vehicles. By
"absorbing" the kinetic energy over a longer
period of time, the safety belts make the

Important things to know
Importance of wearing safety belts and
sitting properly
Airbags are only supplemental restraints. For
airbags to do their job , occupants must al­
ways properly wear their safety belts and be
in a proper seating position.
F or your safety and the safety of your passen­
gers, before driving off, a lways:
• Adjust the dr iver's seat and steering wheel
properly ¢
page 166,
• Adjust the front passenger's seat properly
r=;page 72 ,
• Wear safety be lts properly
r=; page 178,
• Always properly use the proper child re-
stra int to protect children¢
page 205.
In a collision, airbags must inflate within the
blink of an eye and with considerable force .
The supplementa l airbags can cause injuries if
the dr iver or the front seat passenger is not
seated properly . Therefore in order to he lp the
a irbag to do its job, it is important, both as a
d river and as a passenge r to sit properly at all
times.
By keeping room between your body and the
steering wheel and the front of the passenger
compartment, the airbag ca n inflate fully and
comp letely and provide supp lemental p rotec­
tion in ce rtain frontal collisions¢

page 205.
There is a lot that the driver and the passen­
gers can and must do to help the individua l
safety features ins talled in your A udi work to­
gether as a system.
Prope r seat ing pos ition is important so that
the front airbag on the driver s ide can do i ts
job. If yo u have a physical impa irment or con- dition that prevents you from sitting properly
on the driver seat with the safety belt properly
fastened and reaching the peda ls , or if you
have concerns with regard to the function or
operation of the Advanced Airbag System,
please contact your author ized Audi dealer or
qualified workshop, or call Audi Customer Re­
lations at 1-800-822-2834 for poss ible modi­
fica tions to your ve hicle.
When the airbag system deploys, a gas gener ­
ator will f il l the a irbags, break open t he pad­
ded cove rs, and i nflate between the steer ing
whee l and the dr iver and between the instru­
ment pane l and the front passenger. The a ir­
bags will deflate immediately after dep loy­
ment so tha t the front occupants can see
t h ro ugh the windshie ld again witho ut inter­

All of th is takes p lace in the b link o f an eye, so
fast that many peop le don't even realize tha t
the airbags have dep loyed. The airbags a lso
inflate with a great dea l of force and nothing
shou ld be in their way when they deploy.
Front a irbags in combination with properly
wor n safety belts slow down and lim it the oc ­
cupant's forward movement . T ogether they
help to prevent the drive r and front seat pas­
senger from hitting pa rts of the inside o f th e
vehicle while reducing the forces acting on the
occupant dur ing the crash . In this way they
help to reduce the risk of injury to the head
and upper body in the crash. A irbags do not
protect the arms or the lower parts of the
body.
Both front airbags wi ll not inflate in all fronta l
collisions . The t riggering of the airbag system
depends on the vehicle dece lerat ion rate
ca used by the co llision and registered by the
electron ic control unit. If th is rate is below
the reference value programmed into the con ­
t rol unit , the airbags will not be trigge red,
even though the car may be badly damaged as
a res ult of the co llision . Ve hicl e damage, re­
pair costs o r even the lack of ve hicle damage
is not necessari ly an indication of whe ther an
airbag shou ld inflate or not .
