Nissan Maxima Owners Manual: Daytime running light system
The LED portion of the headlights automatically illuminate at 100% intensity when the engine is started and the parking brake released. The daytime running lights operate with the headlight switch in the OFF position. When you turn the headlight switch to the position for full illumination the LED lights switch from daytime running lights to the park function.
If the parking brake is applied before the engine is started, the daytime running lights do not illuminate.
The daytime running lights illuminate when the parking brake is released. The daytime running lights remain on while the engine is running.
It is necessary at dusk to turn the headlight switch on for interior controls and switches to illuminate, as those remain off while the switch is in the OFF position.
When the daytime running light system is active, tail lights on your vehicle are not on. It is necessary at dusk to turn on your headlights. Failure to do so could cause an accident injuring yourself and others.
