Hyundai Equus: ECS (Electronic Controlled Suspension) malfunction warning message

If ECS malfunction warning message comes on while driving, ECS is not working properly.
We recommend that the system be checked by an authorized EQUUS dealer.
✽ NOTICE

CAUTION
If the ECS malfunction message illuminates when there is no air in the suspension, the vehicle height will be very low, so do not drive the vehicle to protect it from the projections on the surface of the ground. Take your vehicle to an authorized EQUUS dealer by towing the vehicle and have the system checked. You should tow the vehicle as shown in the picture.

When you load the vehicle onto the tow truck, the loading angle(1) should be smaller than 6°.
