Remote Trunk Release
Remote Trunk Release Lockout
The switch is located on the inside of the trunk lid,
mounted to the trunk lid latch.
Press the remote trunk release button, located on the
driver's door, to release the trunk lid.
Make sure the remote trunk release lockout feature is
not activated. Also, the remote trunk release will
only work when either the ignition is off, the parking
brake is engaged or the vehicle speed is less than
2 mph (3 km/h).
To turn the lockout on, slide the switch all the way to
the left (ON). To turn the lockout off, slide the switch all
the way to the right (OFF).
When the lockout is on, the remote trunk release switch
on the driver's door will not release the trunk lid.
However, the trunk lid can still be opened with the key,
but not with the remote keyless entry transmitter, if
your vehicle has this feature.
