2021 AUDI A6 battery replacement

Opening and closing


— Keep new or used batteries away from chil-
dren.
— If the battery compartment on a vehicle key
does not close securely, stop using the key
and keep it away from children.
— Seek medical attention immediately if you
suspect that a battery was swallowed or has
entered the body in any other way.

@ For the sake of the environment
Discharged batteries must be disposed of us-
ing
methods that will not harm the environ-
ment. Do not dispose of them in household
trash.
@ Tips
Replacement batteries for the vehicle key
must meet the same specifications as the
original battery.
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.

ZA\ 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 38. 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.

@) Note
The luggage compartment lid can bump into
objects such as the garage ceiling when open-
ing and become damaged.
G) Tips
— When the vehicle is locked, the luggage
compartment lid can be unlocked separately
by pressing the “s button twice on the vehi-
cle key. The luggage compartment lid locks
automatically when it is closed again.
— The ability to open the luggage compart-
ment lid using the handle can be deactivat-
ed or activated in the MMI > page 36.
— Applies to: vehicles with fixed rear backr-
ests: The luggage compartment lid can be
unlocked from the inside in an emergency
=> page 46.
