1500 Air Suspension Controls
Automatic height changes will occur based
on vehicl
e speed and the current vehicle
height. The indicator lamps and instrument
cluster messages will operate the same for
automatic changes and user requested
changes.
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 approx-
imately 1 in (26 mm)) - This position
should b
e 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, push the
height selector switch up once from the
NRH position while the vehicle speed is
below 35
mph (56 km/h). When in the
OR1 posit
ion, 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 ve
hicle speed exceeds 50 mph
(80 km/h),
the vehicle will be automati-
cally lowered to NRH. Off-Road 1 may not
b
e availa
ble due to vehicle payload, an
instrument cluster message will be
displayed when this occurs.
Refer to “Instrument Cluster Display” in
“Getting
To Know Your Instrument Panel”
in the Owner’s Manual for further informa

Off-Road 2 (OR2) (Raises the vehicle approx-
imately 2 in (51 mm)) - This position is
intended
for off-roading use only where
maximum ground clearance is required.
To enter OR2, push the height selector
switch up twice from the NRH position or
once from the OR1 position while vehicle
speed is below 20
mph (32 km/h). While
in OR2, i
f the vehicle speed exceeds
25
mph (40 km/h) the vehicle height will
be automa
tically lowered to OR1.
Off-Road 2
may not be available due to
vehicle p
ayload, an instrument cluster
message will be displayed when this
occurs.
Refer to “Instrument Cluster Display” in
“Getting
To Know Your Instrument Panel”

Aero Mode (Lowers the vehicle approximately
.6 in [15 mm]) – 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 k
m/h) for greater than 20
seconds o
r 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
