■ Battery precautions
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
● Do not swallow the battery.
Doing so may cause chemical
burns.
● A coin battery or button battery
is used in the electronic key. If a
battery is swallowed, it may
cause severe chemical burns in
as little as 2 hours and may
result in death or serious injury.
● Keep away new and removed
batteries from children.
● If the cover cannot be firmly
closed, stop using the electronic
key and stow the key in the
place where children cannot
reach, and then contact your
Toyota dealer.
● If you accidentally swallow a
battery or put a battery into a
part of your body, get emer-
gency medical attention imme-
diately.
