How do you turn off the Daytime Running Lights on a 2001 Toyota 4Runner?

You can't turn off the daytime running lights (DRLs) on a 2001 Toyota 4Runner without modifying the vehicle's electrical system. The 2001 4Runner's DRL system is integrated and not user-adjustable through a switch or setting. Any attempt to disable them would require rewiring or adding a relay, which is not recommended unless you have significant electrical knowledge and are comfortable working with your vehicle's wiring. Improper modifications could damage the vehicle's electrical system or create safety hazards.
