Do not put the key near magnetic items. Electronic devices, such as televisions 
and audio systems emit strong magnetic fields. Note that even a key chain can 
become magnetic.

Keyless Access Remote Reminder

When the keyless access remote is within the

closed, the warning function cancels.

If the keyless access remote is taken out of the vehicle

Removing the keyless access remote from the vehicle 
through a window does not activate the warning 
buzzer.

Do not put the keyless access remote on the 
dashboard or in the glove box. It may cause the 
warning buzzer to go off. Under some other 
conditions that can prevent the vehicle from locating 
the remote, the warning buzzer may also go off even 
if the remote is within the system’s operational 
range.
