& WARNING
• Wiper blades are crucial for safe driving! Only when they are in
good condition are they able to clear the windows properly to
provide uncompromising visibilit y. Worn or damaged wiper blades
are a safety hazard
=> page 82 , "In stalling new wiper blade s"!
• The rain sensor is only designed to assist and support the
driver . It remains entirely the driver' s respon sibility to monitor
out side weather condit ions and to manually acti vate the wipers as
soon as rain or drizzle reduces visibility through the windshield.
• The windshield must not be treated with water-repellent mate­
rial s. They can increa se glare under poor visibility conditions such
as wetness , darkness , or when the sun is low on the horizon. In
addition , they can cau se the wind shield wipers to chatter.

The head restraints on the front seats can be adjusted to
provide safe support to head and neck at the optimum
height and angle. When optimally adjusted, the top of the
restraint should be level with the top of the head
=:> page 205, "Proper adjustment of head restraints".
Height adjustment
- Push the switch up or down to adjust the head restraint
to your height=:,
page 91, fig. 89.
- Adjust the head restraints so that the top of the head
restraint is
at least level with your eyes or higher.
Adjusting the angle Grasp the side of the head restraints with both hands and
push them forward or backward.
Adjusting the side supports - Pull or press the side supports into the desired position
=:, fig. 90.
Refer to=> page 205, "Proper adjustment of head restraints" for
guidelines on how to adjust the height of the front head restraints
to suit the occupant's body size.
& WARNING
• Driving without head restraints or with head restraints that are
not properly adjusted increases the risk of serious or fatal neck
injury dramatically.
• Read and heed all WARNINGS
:::> page 205.
[ i ] Tips
• Correctly adjusted head restraints and safety belts are an
extremely effective combination of safety features.
• Power adjustable head restraints can only be removed by an
authorized repair facility.
• When you adjust the seat toward the front or upward, the head
restraints are automatically lowered to keep them clear of the roof
liner . Be aware that after you move the seat back again toward the
rear or lower it again, the head restraints will not automatically
resume their original position and have to be readjusted. •

Luggage compartment

page 207, "Stowing
luggage".
In a collision , the laws of physics mean that even smaller items that
are loose in the vehicle will turn into heavy missiles that can cause
serious injury. Items in the vehicle pick up kinetic energy which
varies with the vehic le and the weight of the item . Vehicle speed is
the most significant factor.
For example , in a frontal collision at a speed of 30 mph (48 km /h) ,
the forces acting on a 10-lb (4 .5 kg) object are abou t
20 times the
normal weight of the item . This means that the weight of the item
would suddenly be the equivalent of about 200 lbs (90 kg). One can
easily imagine the injuries that an i tem of that weight flying free ly

Roof rack
First things first
A roof rack can be fitted to carry addi tio nal luggage on
the roof.
- Always read and follow the i nstructions provided by the
roof rac k manufacture r w hen t he roof rack system must
be installed.
I f a roof rack or similar luggage carrying equipment is to be
insta lled, please note the following:
• To enhance the vehicle's streaml ined design, rain gu tters have
been molded into the roof. It is not possible to use norma l roof
racks . Only instal l a roof rack sp ecifically designed f or your mo del
A8. Contact the nearest Audi dea ler for information on approved
m odula r roof racks for your veh icle .
Controls and equip ­
ment
• T hese approved roof racks are the basis for a comp lete roof rack
sys tem . Add itio nal attachments for the basic roof rack are neces ­
sary to safe ly transport luggage, bicycles, surf boards, skis or smal l
boats. All necessary hardware fo r these systems is available at your
authorized Audi dea ler.
• We reco mmend t hat you keep the installation i nstructi ons for
your roof rack system together with your Owner's literature in the
vehicle .
When should the ro of r ac k be remo ved ?
• Before g oing th rough an a uto matic car wash (it is bes t to ask the
car wash operator for advice)
• When not i n use, to reduce fue l consumption, wind noise and to
guard against theft.
& WARNING
• Use of an unapproved roof r ack or in corre ct mounting of an
a pp roved roof r ack can c ause the roof rack or the ite ms attached
to it to fall off the roof onto the road .
• Obje cts falling from the roof of a veh icle c an c ause a cras h and
personal inj ury .
• Onl y mount the sy stem between the marking s shown in
=> page 104 , fig. 109.
• The roof ra ck sy stem must be installed e xa ctly a ccording to the
instruction s provided .
0 Note
• Your vehicle warranty does not c over any damages t o 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 installation.
• Always check t he r oof rack m ount ings and hardware before eac h

Turn the ign ition key to position 0 ~ fig . 145 -do not
depress the gas pedal when s tarting the engine .
A cold engine may sound loud after it has been started . This is due
to the hydrau lic valves building up oil pressure. This is normal and
is not a need fo r concern .
I f the engine does not start immediately, stop t rying after 10
seconds and then try to restart the engine about 30 seconds later .
& WARNING
Never sta rt or let the engine run in a confined or en clo sed are a.

& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­

The brake lights illuminate as soon as the brakes decelerate
automatically. •
Changing speed

speed in 5 mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your
speed, e.g . if you want to pass someone. The speed you saved
earlier will resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by 5 mph (10 km/h) for
longer than 5 minutes, the cruise control will turn off temporarily.

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 program is
a combined speed and distance control system.
Fig. 151 Front
bumper: Position of
radar sensor
Adaptive Cruise Control can help make driving more relaxed and
less tiring, particularly 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
will 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 142, "How is the speed stored?" and
=>
page 144, "How is the distance set?" .
Contro ls and eq uip­
ment
Driver information
Important information is brought up in the speedometer and in the
instrument cluster display as the vehicle is being driven
=> page 146, "Driver information" .
What is important for you to know
There are limits to what Adaptive Cruise Control can do as the
vehicle is being driven =>
page 150, "System limitations" .
& WARNING
Improper use of the Adaptive Cruise Control can cause collisions,
other accidents and serious personal injury.
• Always remember that the Adaptive Cruise Control has limits -
it will not slow the vehicle down or maintain the set distance
when you drive towards an obstacle or something on or near the
road that is not moving, such as vehicles stopped in a traffic jam,
a stalled or disabled vehicle.
• Always remember that the Adaptive Cruise Control cannot
detect a vehicle that is driving towards you in your traffic lane and
that it cannot detect narrow vehicles such as motorcycles and
bicycles .
• Never drive at speeds that are too fast for traffic, road and
weather conditions .
• The Adaptive Cruise Control cannot slow or brake the vehicle
safely when you follow another vehicle too closely. Always
remember that the Adaptive Cruise Control has a braking power
that is only about 30% of the vehicle 's maximum braking ability.
Always be prepared to brake and take evasive action to avoid colli­
sions and other accident situations.
• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Control may not be able to _,,,
