Driver inf orma tion d ispl ay
Miles (kilometers ) to empty
The miles (kilometers) to empty indication is a valuable
aid to schedule the refueling stops on a trip .
.,
8 :i: ., m
F ig . 12 Display: miles
(k ilo m eters} to empty
T his feature shows you the estimated range in miles (km)=> fig. 12
until the tank runs dry. This fea ture ca lculates how far you could
drive with the amount of fuel left in your fuel tank while driving
under the current driving conditions. The remaining distance is
recalculated every
6 miles (10 km) .
Whi le calculating the mi les (km) to empty, the system also ca lcu ­
lates your fuel consumption over the last
18 miles (30 km!.
Remember: -the more economically you drive, the further you can
go. •
Open door or trunk lid warning
Fig. 13 D isp lay: o pe n
door o r tr un k wa rning
With the ignition switched on, the open -door-or -lid warning illumi­
nates when at least
one door, or the engine hood or the trunk lid is
not closed. The symbol also shows you
which door(s) or lid is not
closed. The illustration shows that both the dr iver's and the right
rear door are not closed=>
fig. 13.
If the engine hood or trunk lid are not closed, the display will f lash.
As soon as all the doors and lids a re proper ly closed, the warning
goes out .
You can switch off the open -door -or -lid warning display by briefly
pressing the On Board computer control buttons=>
page 38. The
open door or trunk warning will, however, illuminate again as soon
as there is a change in the position of the doors, engine hood or
trunk lid. •

Opening and closing
As a general rule, you should use the remote control key to
lock and unlock the rear lid
c:5 =:> page 51. With the key slot
in the vertical position the rear lid can be
locked and
unlocked
by the power locking system using either the
remote-control- or the fold-out key:::::>
page 50.
Opening the rear lid
-Pull the handle :::::> page 55, fig. 47 while lifting the lid.
Closing the rear lid
-Pull it down and shut it firmly:::::>& . There is a recess in
the interior trim of the lid to make it easier to pull down.
To unlock the rear lid with the key
- Turn the key from the vertical to position @ :::::> page 55,
fig. 46 the lid springs open slightly.
- Open the lid.
To lock the rear lid with the key
-Turn key slot to horizontal position @.
Turning the key counter-clockwise to position @will release the
rear lid and cause it to rise slightly. In this position the key cannot
be pulled out of the lock cylinder.
Turning the key
clockwise to the horizontal position@ and pulling
it out will cause the
lid to remain locked when the power locking
system is actuated.
In this state the rear lid can only be unlocked with the remote
control unlock button
c:::5 on the master key.
After you turn the key
counter -clockwise back to the vertical posi­
tion, the rear lid will again respond to the power locking system.
& WARNING
• After closing the rear lid, always pull up on it to make sure that
it is properly closed. Otherwise it could open suddenly when the
vehicle is moving .
• To help prevent poisonous exhaust gas from being drawn into
the vehicle, always keep the rear lid closed while driving . Never
transport objects larger than those fitting completely into the luggage area, because then the rear lid cannot be fully closed .
• Never leave your vehicle unattended especially with the rear lid
left open. A child could crawl into the car through the luggage
compartment and pull the lid shut, becoming trapped and unable
to get out. To reduce the risk of personal injury, never let children play in or around your vehicle. Always keep the rear lid, as well as
the vehicle doors, closed when not in use.

Lowering the storag e bay bas e
-Move the lever to pos ition @ to lower the var iab le
storage bay=> fig. 56 .
The storage bay bottom can only be lifted when the top i s clos ed

This creates more space in the
luggage compartment . The storage bay base must be in the lowered
position before the top can be lowered.
When the top
o pe ns it folds down completely into the storage bay
des igned to contain it. Only with the storage bay expanded is it
poss ible to open the top . This feature prevents the top from forcing
i t s way down agains t objects blocking its storage space . For this
reason your vehicle has less luggage capacity when the top is down
than when it is up and closed . It is not possible to lift the base of the
storage bay when it contains the folded down top .•
Messages in the instrument cluster display
If the power top fails to activa te when you operate the
control switch, a message will appear in the display to
indicate what is wrong.
Before the power top can start to open or close automatically, a
number of conditions must be met . The systems checks, for
instance, if the storage bay has been expanded before the power
top opens.
The instrument c luster disp lay will generate a message if one of
these condi tions does not check right or if a malfunction occurs .
Power top: ple ase clo se rear lid
The lid on the trunk must always be closed when opening or closing
t he power top . This message will appear in the display if the trunk
lid is not closed .
Power top: pl ease low er stor age ba y

Static electricity can cause sparks that can ignite fuel vapors
released during refueling .
• Never smoke or have an open flame anywhere in or near your
vehicle when refueling or filling a portable fuel container.
• For your safety , we strongly recommend that you do not travel
with a portable fuel container in your vehicle. The container , full or
empty may leak and could cause a fire , especially in a crash .
• If, under e xcept ional circumstances , you must transport a
portable fuel container, please observe the following:
-Never fill a portable fuel container while it is anywhere
in or
on the vehicle (for example , in the luggage compartment , or on
the trunk) . Static electricity can build up while filling and can
ignite fuel vapors causing a fire.
- Always place a portable fuel containe r on the ground before
filling.
- Always keep the filler nozzle completely inside the portable
container before and during filling .
- If filling a portable container made of metal , the filler nozzle
must always be in contact with the container. Thi s will help
prevent static ele ctricity from discharging and cause a fire.
- Never spill fuel inside the vehicle or luggage compartment .
Fuel vapors are h ighly flammable .
- Always observe local and state/provincial laws regarding the
use , storage and transportation of fuel conta iners.

[ i] Tips
• Whenever replacing a fuse, always consult the sticker on the
inside of the fuse panel cover. It contains the most up-to-date infor­
mation regarding the fuse arrangement . If in doubt, ask your autho­
rized Audi Service advisor.
• Some of the equipment items listed are optional or only avail­
able on certain model configurations. •
Bulbs
Replacing light bulbs
For your safety, we recommend that you have your autho­
rized Audi dealer replace burned out bulbs for you.
It is becoming increasingly more and more difficult to replace
vehicle light bulbs since in many cases, other parts of the car must first be removed before
you are able to get to the bulb. This applies
especially to the light bulbs in the front of your car which you can
only reach through the engine compartment.
Sheet metal and bulb holders can have sharp edges that can cause
serious cuts, and parts must be correctly taken apart and then prop­
erly put back together to help prevent breakage of parts and long
term damage from water that can enter housings that have not
been properly resealed.
For your safety, we recommend that you have your authorized Audi
dealer replace any bulbs for you, since your dealer has the proper
tools, the correct bulbs and the expertise.
Gas discharge lamps (xenon lights)*:
Due to the high electrical voltage, have the bulbs replaced by a qual­
ified technician. Headlights with xenon light can be identified by the
high voltage sticker.
& WARNING
Contact with high-voltage components of the electrical system
and improper replacement of gas discharge (Xenon) headlight
bulbs can cause serious personal injury and death.
• Xenon bulbs are pressurized and can explode when being
changed.
• Changing Xenon lamps requires the special training, instruc­
tions and equipment.
• Only an authorized Audi dealer or other qualified workshop
should change the bulbs in gas discharge lamps.
& WARNING
There are parts with sharp edges on the openings and on the bulb holders that can cause serious cuts .
