Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Automatic Control Mode
A number of control conditions apply when the interior lights are in the automatic mode.
The interior lights can be on for several different time periods depending on the trigger source. The OFF conditions are only delayed by the ramp down duration (2.6 seconds).
- On Conditions - 16 Minutes
- One or more doors are opened
- Tailgate is opened
- Inertia switch triggered with ignition in position 1 or 2
- MRS4 System triggered
- On Conditions - 20 Seconds
- External unlock (either with the key or remote transmitter)
- Ignition switched to position 0 from 1
- On Conditions - 10 Seconds
- External remote transmitter lock with vehicle already locked and alarm armed (Locating feature).
- Off Conditions
- External lock (either with the key or remote transmitter)
- If any door or tailgate is open for more than 16 minutes
- Inertia switch reset
- 16 minutes after the last valid on condition
- Interior light switch pressed when interior lights are on
- All doors and tailgate shut with ignition status either on position 1 or 2 (If the interior lights are not activated by the interior light switch)
- All doors and tailgate shut with the ignition in the 0 position (delay time = 20 seconds)
When in automatic mode the newest request for action will over-ride the current state. Also, the power saving mode (16 minutes) will be cancelled when all of the doors or the tailgate are shut or if any other valid ON/OFF signal is received.
