ZA WARNING
If batteries or coin cell batteries are swal-
lowed or enter the body in any other way, they
can cause serious or fatal injuries within a
short period of time. There is a risk of chemi-
cal burns.
— Keep vehicle keys and key fobs with batter-
ies out of the reach of children.
— 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
using methods that will not harm the environ-
ment. Do not dispose of them in household
trash. They contain harmful substances and
recyclable raw materials. Contact an author-
ized Audi dealer or authorized Audi Service
Facility for more information.
@® Tips
Replacement batteries for the remote control
key must meet the same specifications as the
original battery.

PANIC
PANIC
If you unlock the vehicle but then do not open
any of the doors, the luggage compartment lid,
or the hood within a short period time, the vehi-
cle will lock again automatically. This feature pre-
vents the vehicle from being accidentally left un-
locked for a long period of time.
The settings in the Infotainment system deter-
mine if the entire vehicle or only the driver's door
is unlocked when unlocking the vehicle
> page 23.

Z\ WARNING
No one, especially children, should stay in the
vehicle when it is locked from the outside, be-
cause the windows can no longer be opened
from the inside > page 24. Locked doors
make it more difficult for emergency workers
to get into the vehicle, which puts lives at risk.
@ Tips
— Only use the remote control key when you
are within view of the vehicle.

— The selector lever must be in the P position
on vehicles with a convenience key*; other-
wise the vehicle will not lock.
— Do not use the vehicle key to lock and un-
lock when you are inside the vehicle. Other-
wise, you could trigger the anti-theft
alarm. If this happens, press the fj unlock
button.
— Only use the panic function in an emergen-
cy.
