The driver and front passenger Belt-Minder feature can be deactivated by performing the following procedure.

Before following the procedure, make sure that:

* The parking brake is set
* The gearshift is in P (Park)
* The ignition switch is in the off position
* The driver and front passenger safety belts are unbuckled

1. Turn the ignition switch to the on position. Do not start the engine.

2. Wait until the safety belt warning light turns off. (approximately 1 minute)

* Step 3 must be completed within 30 seconds after the safety belts warning light turns off.

3. For the seating position being disabled, buckle then unbuckle the safety belt 3 times, ending in the unbuckled state.

* After step 3, the restraint system warning light (airbag light) will be turned on for 3 seconds.

4. Within approximately 7 seconds of the light turning off, buckle then unbuckle the safety belt.

* This will disable the Belt-Minder feature for that seat position if it is currently enabled. As confirmed, the restraint system warning light will flash four times per second for 3 seconds.
