AIR SUSPENSION SYSTEM
• The air suspension system provides full time load leveling capability along withthe benefit of being able to adjust vehicle height by the push of a button.
• Automatic height changes will occur based on vehicle speed and the current vehicle height. The indicator lamps and EVIC messages will operate the same for
automatic changes and user requested changes.
Description
• Normal Ride Height (NRH) - This is the
standard position of the suspension
and is meant for normal driving.
• Off-Road 1 (OR1) (Raises the vehicle
approximately 1 in (26 mm) - This posi-
tion should be the primary position for
all off-road driving until Off Road 2
(OR2) is needed. A smoother and more
comfortable ride will result. To enter
OR1, press the “Up” button once from
the NRH position while the vehicle speed is below 35 mph (56 km/h). When in the
OR1 position, if the vehicle speed remains between 40 mph (64 km/h) and
50 mph (80 km/h) for greater than 20 seconds or if the vehicle speed exceeds
50 mph (80 km/h), the vehicle will be automatically lowered to NRH. Off-Road 1
may not be available due to vehicle payload, an EVIC message will be displayed
when this occurs. Refer to “Electronic Vehicle Information Center (EVIC)” in
“Understanding Your Instrument Panel” for further information.
• Off-Road 2 (OR2) (Raises the vehicle approximately 2 in (51 mm) -
This position is
intended for off-roading use only where maximum ground clearance is required.
To enter OR2, press the “Up” button twice from the NRH position or once from the
OR1 position while vehicle speed is below 20 mph (32 km/h). While in OR2, if the
vehicle speed exceeds 25 mph (40 km/h) the vehicle height will be automatically
lowered to OR1. Off-Road 2 may not be available due to vehicle payload, an EVIC
message will be displayed when this occurs. Refer to “Electronic Vehicle Information
Center (EVIC)” in “Understanding Your Instrument Panel” for further information.
• Aero Mode (Lowers the vehicle approximately .6 in (15 mm) – 1500 Models Only - This
position provides improved aerodynamics by lowering the vehicle. The vehicle will
automatically enter Aero Mode when the vehicle speed remains between 62 mph
(100 km/h) and 66 mph (106 km/h) for greater than 20 seconds or if the vehicle
speed exceeds 66 mph (106 km/h). The vehicle will return to NRH from Aero Mode
if the vehicle speed remains between 30 mph (48 km/h) and 35 mph (56 km/h) for
greater than 20 seconds or if the vehicle speed falls below 30 mph (48 km/h).
