AIR SUSPENSION SYSTEM — IF EQUIPPED
D
ESCRIPTION
This 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. There
are two selectable heights that can be chosen
based on your operating conditions.
The system requires that the ignition be in the
ON/RUN position or the engine running with zero
vehicle speed for all user requested changes and
load leveling.
Rear Leveling Ride Height Switch
Normal Ride Height (NRH) – This is the standard
position of the suspension and is meant for normal
driving. It will automatically adjust to maintain the
rear ride height as conditions change.
Alternate Trailer Height (ATH) – Lowers the vehicle
approximately 1 inch (25 mm) for a level truck, to
be used as required while trailer towing. It will
automatically adjust to maintain the rear ride
height as conditions change.
Trailer Decoupling/Unloading – The air suspension
system will continue to load level after the vehicle
has been turned off for 10 minutes without
compressor activation. This allows for easy
removal of a trailer and/or load from the back of
the truck by maintaining the ride height. After
10 minutes you will need to turn the ignition to the
ON/RUN position for the air suspension to re-level
due to addition/removal of load in the vehicle. If
the air suspension system is disabled using the
settings menu (Tire Jack Mode, Transport Mode,
Alignment Mode, or Bed Lowering Mode) the
system will remain disabled when the vehicle is
turned off. Reactivating the air suspension can be
accomplished via the settings menu or driving the
vehicle above 5 mph (8 km/h) for Tire Jack Mode,
Alignment Mode, Transport Mode and Bed
Lowering Mode.
NOTE:
Most 3500 models will not lower to Alternate
Trailer Height (ATH) when unloaded.
