⚠️ Please Read Before Installation
Do not drive the vehicle while the ride height is in the “adjusted” position — it may cause suspension or component damage.
The ASE662 is designed exclusively for vehicles with the designated harness (H-076). Do not install on incompatible models.
During periodic vehicle inspections or testing (e.g., Japan’s Shaken), this unit must be removed or disabled, as regulations vary by inspection center.
Improper use may cause tire wear, handling instability, or component failure.
Installation must be carried out by a qualified technician or professional installer.
Product design and specifications are subject to change without notice.
