the override, remove the rubber tray from the storage bin
located to the right of the shift lever. The override access
port is at the top of the bin to the right of the shift lever
gate.

(RUN position with Keyless Go™) without starting the
engine.
2. Firmly set the parking brake.
3. Press and maintain firm pressure on the brake pedal.
4. Using the screwdriver, press and hold the override tab
through the access port on the center console.
