Luggage compartment
Tie-down eyelets
The luggage c ompartment is equipped with four tie -down
eyelets to secure luggage and other items.

-Read and heed all WARNINGS =:> page 205, "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 about
20 times the
normal weight of the i tem . 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 tha t weight flying free ly _,,,

& WARNING
For strength-related reasons, the mounting hooks can only be
used to secure objects weighing up to 10 lb .

& WARNING
• The ski sack is intended only for the transportation of skis and
other light objects. To reduce the risk of serious personal injury,
never transport heavy or pointed objects in the ski sack.
• When braking rapidly or during an accident, the load could be
displaced and cause injury to occupants.
• Sharp edges on the load must be covered for protection.
Always fasten the belt tightly around the sack and its contents

stowing it away. •
Roof rack
First things first
A roof rack can be fitted to carry additional luggage on
the roof.
- Always read and follow the instructions provided by the
roof rack manufacturer when the roof rack system must
be installed.
If a roof rack or similar luggage carrying equipment is to be
installed, please note the following:
• To enhance the vehicle's streamlined design, rain gutters have
been molded into the roof. It is not possible to use normal roof
racks. Only install a roof rack specifically designed for your model
A8. Contact the nearest Audi dealer for information on approved modular roof racks for your vehicle.
Controls and equip­
ment
• These approved roof racks are the basis for a complete roof rack
system. Additional attachments for the basic roof rack are neces ­
sary to safely transport luggage, bicycles, surf boards, skis or small
boats. All necessary hardware for these systems is available at your
authorized Audi dealer.
• We recommend that you keep the installation instructions for
your roof rack system together with your Owner's l iterature in the
vehicle.
When should the roof rack be removed?
• Before going through an automatic car wash (it is best to ask the
car wash operator for advice)
• When not in use, to reduce fuel consumption, wind noise and to
guard against theft.
& WARNING
• Use of an unapproved roof rack or incorrect mounting of an
approved roof rack can cause the roof rack or the items attached
to it to fall off the roof onto the road.
• Objects falling from the roof of a vehicle can cause a crash and
personal injury.
• Only mount the system between the markings shown in
~ page 104, fig. 109.
• The roof rack system must be installed exactly according to the
instructions provided.
(D Note
• Your vehicle warranty does not cover any damages to the vehicle
caused by using roof racks or mounting struc tures not approved by
Audi for your vehicle. The same applies to damage resulting from
incorrect roof rack installation.
• Always check the roof rack mountings and hardware before each
trip and during a trip to make sure everything is securely tightened.

A cold engine may sound loud after it has be en started. This is due
to the hydrau lic valves building up oil pressure. This is normal and
is not a n eed fo r concern .
I f the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later .
& WARNING
Never start or let the engine run in a confined or en clo sed are a.
Exhaust fumes from the engine contain carbon monoxide, a color ­
less and odorle ss gas . Carbon mono xide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended

sions, do not let your vehic le stand and warm up. Be ready to drive
off im mediately afte r starting your vehicle . Maintain modera te
speed until the engine is completely warm . Remember , the engine
performs best at operating temperature. •

On the road -----------------
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- Move the selector lever into the
P position => &.
- Switch off the engine and remove the ignition key from
the ignition lock.
When you park your vehicle on hills, do the
following
- Stop the vehicle using the brake pedal.
- Pull the switch to apply the electromechanical parking
brake.
- If you are parking headed
downhill, turn the front wheels
toward the curb.
- If you are parking headed
uphill, turn the front wheels
awayfrom the curb.
- Move the selector lever into the
P position.
- Switch off the engine and remove the ignition key from
the ignition lock.
& WARNING
This is how you can reduce the risk of injury when leaving your
vehicle.
Controls and equip­ ment
&, WARNING (continued)
• Never park the vehicle where it can come in contact with dry
grass, spilled fuel or any other flammable materials.
• When parking on hills, always turn the wheels so that the front
wheels will first roll into the curb, if the vehicle should start to roll.
• Never allow anyone -especially small children -to remain
in the
vehicle when it is locked. Locked doors make it more difficult for
rescuers to access the passenger compartment in the event of an
emergency. Danger to life!
• Never leave children unsupervised in the vehicle. Children
could release the parking brake or move the gearshift lever out of
gear. The vehicle could start to roll away and cause an accident.
• No matter what the season is, the temperature in a parked
vehicle can reach dangerous levels.
0 Note
• Please exercise care when you park your vehicle in parking areas
with parking barriers or curbs . Parking barriers and curbs vary in
height and could damage your bumper and related components as
the front of your vehicle moves over a barrier or curb that is too high, as you park or as you back out of a parking spot. In order to be
sure that no such damage can occur, you may wish to stop short of
having the front tires of your car touch the parking barrier or curb.
• Please also exercise exceptional care when you drive up or down
steep ramps or drive over curbs or other obstacles, for which the
vehicle is not designed , because components of the vehicle close to
the ground, such as bumper covers, spoilers and suspension and
exhaust system components, may become damaged. •

the lever . If you keep the lever pressed down, you will alter your
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.
The green symbol in the
display=> page 137, fig . 150 is replaced
with a white symbol. The saved speed remains the same. •

• Damage caused by accidents (e.g . if the vehic le is damaged
when parking) can affect the radar sensor settings. This can cause
the system to malfunct ion or switch off completely.
• In winter conditions, you should check the radar sensor cover
before driving to make sure it is free of ice and snow. If necessary ,
clean the area near the radar sensor
carefully => page 139, fig. 151.
• To ensure that the radar sensor is not blocked, foreign objects
(e.g. stickers, larger license plate mounts, add -on parts) must not
cover the area near the radar
sensor=> page 139, fig . 151. The area
near the radar sensor must not be painted, either .•
Ap plies to vehicles: with Ad aptive Crui se Co nt rol
How does Adaptive Cruise Control work?
Vehicles traveling ahead are detected with the aid of the
radar sensor.
Fi g. 152 Ra dar sens or
me asuremen t range
A forward -look ing radar sens or in the fro nt b umper monitors the
traffic situation ahead . Vehicles moving in your direction can be
de tec ted up to a distance of a bout 140 yards ( 130 meters) but the
Adaptive Cruise Contro l cannot detect vehicles that are stopped or

Driving in tr affi c
If you start to catch up with a vehic le in front of you, Adap tive Cruise
Control automatically slows your vehic le to a speed that will he lp
you stay a safe distance back .
If the vehicle in front acce lerates, Adaptive Cruise Control a lso accel -
erates up to the speed that you have set . .,_
