Automatic Headlight Leveling System in Toyota Fortuner

The Automatic Headlight Leveling System (AHLS) is a crucial feature in modern vehicles that improves driver visibility and ensures the safety of both the driver and other road users. Toyota Fortuner, a mid-size SUV, is one of the vehicles equipped with this technology.

Toyota Fortuner second generation.

The Automatic Headlight Leveling System (AHLS) is a technology designed to automatically adjust the angle of a vehicle’s headlights to ensure optimal visibility and safety on the road. The system works by using sensors to detect changes in the vehicle’s position and load, which then trigger the AHLS to adjust the headlights’ direction accordingly.


In Toyota Fortuner, the AHLS uses a sensor that detects changes in the vehicle’s pitch. These changes can be caused by various factors, such as acceleration, braking, or a change in the vehicle’s weight distribution.

Overall, the AHLS is an essential safety feature that helps improve driver visibility, reduce glare, and ensure the safety of other road users. With this technology, Toyota Fortuner drivers can enjoy better visibility and safer driving experience, especially during night-time or low-light conditions.

Can you adjust auto leveling headlights?

The Automatic Headlight Leveling System (AHLS) is designed to automatically adjust the headlights’ angle. While some vehicles may have a manual mode that allows the driver to adjust the headlights’ angle manually, the AHLS in Fortuner is not meant to be manually adjusted by the driver.

This is because the AHLS is a complex system that uses sensors and advanced algorithms to ensure that the headlights are always at the optimal angle for the given driving conditions.

If you notice that your headlights are not properly aligned, it is recommended that you take your vehicle to a certified mechanic or dealership to have the AHLS checked and calibrated. They will be able to diagnose any issues with the system and make the necessary adjustments to ensure that your headlights are properly aligned and functioning as they should.
