Step 1:
With the parking brake on, place the car in
neutral and remove the center console trim by
pulling outwards to release the clips. Be sure to
disconnect the traction control & lighter
harnesses before removing from vehicle

Step 2:
Depress the two clips and remove the lighter
from the console trim as shown.

Step 3:
Feed the wires from the push start through the
trim and install the lock nut to secure the
button. Be sure the wording “Engine Start” is
facing the correct way before tightening the
lock nut.

Step 4:
Feed the push start wires through the drivers’
