PERIMETER ALARM SYSTEM
The perimeter anti-theft system will help protect your vehicle doors,
hood and trunk from unauthorized entry.
When the vehicle is armed the power door locks and remote trunk
release control are disabled. These will not work until the vehicle is
disarmed. Refer to Driver Controls chapter for more information.
If there is any potential perimeter anti-theft problem with your vehicle,
ensure ALL remote entry transmitters are brought to the dealership,
to aid in troubleshooting.
Theft indicator
When the perimeter alarm is armed, the theft indicator on the
instrument panel will flash briefly every two seconds to indicate the
perimeter alarm system is protecting your vehicle.
