NOTE:Do not attempt to make a shift while only the
front or rear wheels are spinning. The front and rear
driveshaft speeds must be equal for the shift to take
place. Shifting while only the front or rear wheels are
spinning can cause damage to the transfer case.
Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.
NOTE: Delayed shifts out of four-wheel drive may be
experienced due to uneven tire wear, low or uneven tire
pressures, excessive vehicle loading, or cold tempera-
tures.
WARNING!
You or others could be injured or killed if you leave
the vehicle unattended with the transfer case in the
(Continued)
WARNING! (Continued)
NEUTRAL position without first fully engaging the
parking brake. The transfer case NEUTRAL position
disengages both the front and rear drive shafts from
the powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The parking
brake should always be applied when the driver is
not in the vehicle.
For additional information on the appropriate use of each
transfer case mode position, see the information below:

NOTE:If equipped with a touch screen radio all
enabling/disabling of air suspension features must be
done through the radio. Refer to “Uconnect Settings” in
“Understanding Your Instrument Panel” for further in-
formation.
WARNING!
The air suspension system uses a high pressure
volume of air to operate the system. To avoid per-
sonal injury or damage to the system, see your
authorized dealer for service.
Air Suspension Modes
The Air Suspension system has multiple modes to protect
the system in unique situations:
Tire/Jack Mode
To assist with changing a spare tire, the air suspension
system has a feature which allows the automatic leveling to be disabled. Refer to “Electronic Vehicle Information
Center (EVIC) or Driver Information Display (DID)” in
“Understanding Your Instrument Panel” or “Uconnect
Settings” in “Understanding Your Instrument Panel” if
equipped with a touch screen radio for further informa-
tion.
NOTE:
This mode is intended to be enabled with engine
running.
Transport Mode
