Page 526 of 916

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
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:
2H
Rear-Wheel Drive High Range — This range is for
normal street and highway driving on dry hard surfaced
roads.
4H
Four-Wheel Drive High Range — This range locks the
front and rear driveshafts together forcing the front and
rear wheels to rotate at the same speed. Additional
traction for loose, slippery road surfaces only.
Neutral (N)
Neutral — This range disengages the front and rear
driveshafts from the powertrain. To be used for flat
towing behind another vehicle. Refer to “Recreational
Towing” in “Starting And Operating” for further infor-
mation.

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.
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” for further in-
formation.
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

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. After the “ALT TRAILER HEIGHT”
button has been pushed, it will blink continuously until
the trailer height has been achieved.
The system requires that the ignition be in ON/RUN
position or the engine running with zero vehicle speed
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
