AFS (Adaptive Front-Lighting System)

WARNING: This page is about a different car, the 2008 Infiniti M45 and 2008 Infiniti M35. However, it is still accessible from the selected car via links, so may be relevant.

AFS increases view ability of cornering direction by changing light axis automatically to the direction of travel with low beam headlamps during vehicle's cornering.

AFS switch allows AFS function to be stopped.

AFS control unit determines the current vehicle conditions by each received signals, and sends commands to the low beam headlamp to swivel. With the headlamps (HIGH/LOW) illuminated, the AFS switch on, engine running and the A/T select lever in any position but range P or range R, the low beam headlamps are operative by AFS control unit commands.

As the steering wheel is turned to the left (right), the left (right) low beam headlamp will automatically swivel angle in accordance with the steering angle and vehicle speed, and stop the operation when the steering wheel is returned to the straight-ahead position.

Swivel operation allows drive signal to be sent to the swivel actuator on the side that AFS control unit is actuated. Step motor built in swivel actuator adjusts low beam projector of headlamp to swivel angle that matches drive signal. Swivel position sensor built in swivel actuator detects swivel angle and transmits a swivel position sensor signal to the AFS control unit. AFS control unit monitors if swivel operation is performed normally via swivel position sensor signal.

SWIVEL OPERATION CHART

(1) Included high beam illuminated.
(2) The swivel operates when running at approx. 25 km/h (15.5 MPH). When swivel operation is started, it works on until vehicle stops.
(3) The low beam headlamps perform small movements when AFS control unit detects start of the engine. This is normal with initialization of swivel actuator by AFS control unit.
