KEYS AND DOORS INFORMATION D If you close the trunk lid while a smart key is left in the trunk, an alarm should be activated. However, if the key is placed near the spare tire or at the edge of the trunk, or if the key is in a metallic bag, the trunk lid might not be unlocked. D If you accidentally lock a smart key in the trunk, be aware that anyone can unlock the trunk by pushing the trunk button. "Key reminder alarm If you lock your key in the trunk, an alarm sounds for 10 seconds to remind you that the key is in the trunk. To stop the alarm, push the trunk button. At this time, the trunk lid is unlocked. Even after the alarm stops sounding, pushing the trunk button will unlock the trunk lid. D Even when the smart key is outside the trunk, an alarm still might be activated if the key is near the trunk. However, if you have the key, there is no problem. 11L237a 32
