The air suspension system is a rear leveling ride height system. The main purpose of this system is to maintain the truck's rear ride height level.
Rear Leveling Ride Height Switch
Normal Ride Height (NRH) - This is the standard position of the suspension and is meant for normal driving.
Trailer Mode (Lowers the vehicle approximately 1 in (25 mm) - This position will lower the rear suspension and provide load leveling for all loading conditions including towing a trailer. The trailer button will blink continuously until trailer height has been achieved.
The system requires that the ignition be in ON/RUN position or the engine running for all user requested changes.
After the engine is turned off, it may be noticed that the air suspension system operates briefly, this is normal. The system is correcting the position of the vehicle to ensure a proper appearance.
NOTE: If equipped with a touch screen radio all enabling/disabling of air suspension features must be done through the radio. Refer to "Uconnect Access Settings" in "Understanding Your Instrument Panel" for further information.
WARNING! The air suspension system uses a high pressure volume of air to operate the system. To avoid personal injury or damage to the system, see your authorized dealer for service.
