— After closing the luggage compartment lid,
make sure that it is latched. Otherwise the
luggage compartment lid could open sud-
denly when driving, which increases the risk
of an accident.
— Never drive with the luggage compartment
lid ajar or open, because poisonous gases
from the surrounding area can enter the ve-
hicle interior and increase the risk of asphyx-
iation.
— Never leave your vehicle unattended when
the luggage compartment lid is open. A
child could climb into the vehicle through
the luggage compartment. If the luggage
compartment lid was then closed, the child
would be trapped in the vehicle and unable
to escape. To reduce the risk of injury, do not
allow children to play in or around the vehi-
cle. Always keep the luggage compartment
lid and the doors closed when the vehicle is
not in use.

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you.
It is becoming increasingly more and more diffi-
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re-
moved 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, parts must be
correctly taken apart and then properly put back
together to help prevent breakage of parts and >
