Automatic Height Change Warnings
When the suspension is locked at access height, the CHCM will change the suspension height automatically when the vehicle speed exceeds 40 km/h (24 mph). The control module issues a warning to advise the driver that the vehicle is approaching the speed threshold when the speed reaches 35 km/h (22 mph). The instrument cluster sounder will emit a chime, a message will be displayed in the message center and the Normal height indicator and the raising indicator will flash.
The warning is removed when the vehicle speed is reduced.
