How do I know my vehicle is equipped with AFS?

Each manufacturer may choose to implement the AFS function in a slightly different way. Here are some suggested methods to determine if your vehicle is equipped with an AFS system.

• Ask sales person at dealership
• Check owner’s manual
• Observe movements or changes in light pattern during driving on curvy roads
• Lens markings (for future consideration)
• Marketing information, brochures
• Manufacturers web page
• Initialization sequence may be visible when headlamps are turned on while vehicle is stationary. Because of the complex mechatronics of those systems, an initialization sequence is required which maybe visible.
• Option summary on window sticker

Is AFS more glaring than conventional headlamp systems?

AFS should reduce glare under most driving conditions. In right-hand turns, the headlamp beam is being directed away from the oncoming traffic. In left-hand turns, the beams will not cross the center line any worse than if on a straight road.

Can I retrofit my current headlamps with AFS?

NO. These systems are designed to be integrated with the overall vehicle system and therefore do not lend themselves for retrofit installation.

Can I upgrade my current headlamp system to an AFS system?

Certain car manufacturers may offer upgrades to the conventional headlight system. These systems are designed to be integrated with the overall vehicle system. The installation should only be done by the dealership when possible.

Will my night time driving visibility improve with these systems?

Night time driving visibility will generally be improved under many road and environmental conditions.

Bending light provides additional illumination in the direction of the turn. Pedestrians, obstacles, road features, and signs can be detected sooner and will lead to improved reaction time.

Why would I want AFS? (I am a good driver, why…)

Even the best drivers can only react to what they see. AFS enhances the field of vision and visibility during a variety of driving situations such as, night-time, fog, adverse weather, highway, and city conditions. AFS systems provide more information to allow the driver to make better judgments while driving. The driver has a better chance to react sooner to dynamic situations on the road.

Is AFS better than HID?

HID was designed to maximize light on the road.

AFS is designed to direct the vehicles beam pattern to provide greater illumination for various road situations such as turns, motorway lighting, city and adverse weather. AFS compliments both halogen and HID systems.

Can I turn AFS on and off?

Currently there are no legal requirements for switching. The manufacturer of the vehicle may or may not incorporate this feature.

How do I know my AFS System is legal?

Factory installed AFS headlamps marked DOT are designed to meet all legal requirements in the US. Verify that DOT marking is present on the lens.

SAE J2591 is an industry standard that outlines design, installation and validation for AFS systems. (Document available from SAE, click here to view )
