Head Lamp Leveling Device: Other Hyundai Equus II

Operating Procedure

1. Suspension angle change resulted from vehicle's load change.
2. Sensor angle change.
3. Microprocessor calculates necessary head lamp angle change amount.
4. Sending a proper signal to head lamp levelling device and driving actuator.

Operating Condition

1. Ignition on
2. Low beam on
3. On stop: If sensor lever change is 2° and above, head lamp is operated after max. 1.5 sec.
4. On driving: If vehicle velocity is over 4km/h(2.48mile/h), velocity change is not over 0.8-1.6km/h(0.5 ~ 1.0mile/h) per second, and loading condition is changed, then head lamp is operated.
