Luggage compartment
lid
General information

— After closing the luggage compartment lid,
make sure that it is latched. The luggage
compartment lid could open suddenly while
driving, which would increase 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.
— If there is a luggage rack (such as a bicycle
rack) on the luggage compartment lid, the
luggage compartment lid may not open
completely under certain circumstances or it
could close by itself if open due to the extra
weight. Therefore, the open luggage com-
partment lid must be given additional sup-
port or the cargo must first be removed
from the luggage rack.
— Applies to vehicles with power-operated or
sensor-controlled luggage compartment lid:
Pay careful attention when closing the lug-
gage compartment lid. Otherwise, you could
cause serious injury to yourself or others de-
spite the pinch protection.

ZX WARNING
— Applies to vehicles with anti-theft alarm sys-
tem: When the vehicle is locked from the
outside, no one - especially children - should
remain in the vehicle, because the windows
can no longer open from the inside
= page 44. Locked doors make it more diffi-
cult for emergency workers to enter the ve-
hicle, which puts lives at risk.
— Always close and lock the luggage compart-
ment lid and the doors when the vehicle is
not in use. Otherwise someone such as a
child could enter the vehicle through the
luggage compartment and become locked
inside it. To reduce the risk of injury, do not
allow children to play in or around the vehi-
cle.
— To reduce the risk of injuries by pinching,
make sure that no one is in the operating
area of the luggage compartment lid, in-
cluding the hinge areas and the upper and

lower edge of the luggage compartment lid.

tion when they are routed correctly. Incorrect
seating positions significantly reduce the protec-
tive functions of the safety belts and increase the
risk of injury due to incorrect belt routing.

occupants. This is not a complete list. Audi would
simply like to increase your awareness of the top-
ic. The following points apply when the vehicle is

crease the risk of serious or fatal injury to ve-
hicle occupants, especially if the airbags de-
ploy and come into contact with occupants
who are not seated correctly. Note the impor-
tant information and warnings in the chapters
for the topics given above.
G) Tips
— Save your seat profile* > page 83. This al-
lows you to access your personal seat profile
quickly and easily at any time.

braking maneuvers, which increases the risk
of an accident. Store objects securely while
driving.
— Applies to: vehicles with front center arm-
rest The center armrest must remain closed
while driving. Otherwise, the protective
function of the front center airbag could be
impaired because it deploys from the driv-
er's seat backrest. This increases the risk of
injury.

the ignition is switched off. To reduce the
risk of injury, children should never be left
unattended in the vehicle for this reason.

Fig. 64 Correctly-adjusted head restraint
Make sure that:
— The upper edge of the head restraint is as even
as possible with the top of your head
— The head restraint is as close as possible to the
back of the head
— The head restraints on the occupied rear seats
are positioned all the way up or folded upward.

Z\ WARNING
— There is one head restraint for each seat. All
vehicle occupants must adjust the head re-
straint correctly before every trip. Having
head restraints that are not adjusted cor-
rectly or not installed in the vehicle increas-
es the risk of a neck injury during sudden or
unexpected driving or braking maneuvers or
in a collision.

it is necessary to install a child safety seat
= page 88. Stow the removed head re-
straints securely, for example in the luggage
compartment. Reinstall the head restraints
immediately once the child safety seat has
been removed. Driving without head re-
straints increases the risk of serious neck in-
juries.
— Depending on the equipment, the front
head restraints may be active head re-
straints. If triggered, a part of the head re-
straint will move several inches forward to
provide additional support to the head. If

triggered, have the head restraints serviced
