Apparatus for automatically initiating sequence of vehicle functions

An apparatus for automatically initiating a plurality of vehicle functions, the apparatus comprising:

• a mobile unit;
• a detection device transmitting a first interrogation signal within a first zone, wherein the mobile unit transmits a first identification signal in response to the first interrogation signal when the mobile unit is disposed within the first zone, wherein the detection device automatically detects whether the mobile unit is within the first zone by matching the first identification to a first predetermined identifier, wherein the detection device transmits a second interrogation signal within a second zone, wherein the mobile unit transmits a second identification signal in response to the second interrogation signal when the mobile unit is disposed within the second zone, wherein the detection device automatically detects whether the mobile unit is within the second zone by matching the second identification to a second predetermined identifier, wherein the first zone and second zone are outside the vehicle and wherein the first zone encompasses the second zone;
• and
• a controller initiates a vehicle light to illuminate when the detection device detects that the mobile unit is within the first zone, the controller automatically terminates the illumination of the vehicle light after a predetermined time after the mobile unit is not detected within the second zone after the mobile unit has been detected in the first zone, the controller maintains the first function when the mobile unit is detected in the second zone, the controller further initiates a vehicle closure to enter an unlock-standby state when the detection device detects that the mobile unit is within the second zone, wherein the controller creates a sound when the detection device detects that the mobile unit is within the first zone, and wherein the controller initiates a second vehicle function when the detection device detects that the mobile unit is within the second zone, the second vehicle function chosen from a group consisting of opening a vehicle closure, energizing an opener switch, and actuating a vehicle ingress/egress device.
