If the suspension is outside normal ride height (amber lamp on), the ECAS system will automatically return the suspension to normal ride height when vehicle speed reaches or exceeds a set speed (usually set to 5 mph).
Messages about the ride height status will display in the message field of the driver message center.
ECAS Standby Mode, Remote Control
Once the key is turned off, the ECAS will enter Standby mode, remaining powered and adjusting to level and load changes for 1 hour. To cancel Standby mode on vehicles with a remote control, turn on the remote control then hold the STOP key on the remote for 2 seconds. Confirm the deactivation of standby mode by attempting to turn the remote on and adjust the suspension, which should not be possible.
