NEUTRAL
This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle. Refer
to “Recreational Towing” in “Starting And Operating” for
further information.

WARNING!
The air suspension system uses a high pressure vol-
ume of air to operate the system. To avoid personal
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

ers the vehicle to entry/exit ride height. Refer to “Uconnect
Settings” in “Multimedia” for further information. NOTE:
This mode is intended to be enabled with engine
running.
Transport Mode
To assist with flat bed towing, the air suspension system
has a feature which will put the vehicle into Entry/Exit
height and disable the automatic load leveling system.
Refer to “Uconnect Settings” in “Multimedia” for further
information.
NOTE: This mode is intended to be enabled with engine
running.

WARNING!(Continued)
•Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL. Always, block or
chock the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.
Towing Requirements — Tires
• Do not attempt to tow a trailer while using a compact
spare tire.
•
Proper tire inflation pressures are essential to the safe and
satisfactory operation of your vehicle. Refer to “Tires” in
“Servicing And Maintenance” for proper tire inflation
procedures.
• Check the trailer tires for proper tire inflation pressures
before trailer usage.
• Check for signs of tire wear or visible tire damage before
towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.
•
When replacing tires, refer to “Tires” in “Servicing And
Maintenance” for the proper tire replacement procedures.
Replacing tires with a higher load carrying capacity will
not increase the vehicle’s GVWR and GAWR limits.
Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.
• An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
• Trailer brakes are recommended for trailers over
1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).

IN CASE OF EMERGENCY 403

WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired
or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped endof the nut toward the wheel. Lightly tighten the lug
nuts.

Four-Wheel Drive Models
The manufacturer recommends towing with all wheels
OFFthe ground. Acceptable methods are to tow the vehicle
on a flatbed or with one end of vehicle raised and the
opposite end on a towing dolly.
If flatbed equipment is not available, and the transfer case
is operable, vehicles with a two-speed transfer case may
be towed (in the forward direction, with ALLwheels on the
ground), IFthe transfer case is in NEUTRAL (N) and the
transmission is in PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed instructions.
Vehicles equipped with a single-speed transfer case have
no NEUTRAL position, and therefore mustbe towed with
all four wheels OFFthe ground.

Run Flat Tires — If Equipped
Run Flat tires allow you the capability to drive 50 miles
(80 km) at 50 mph (80 km/h) after a rapid loss of inflation
pressure. This rapid loss of inflation is referred to as the
Run Flat mode. A Run Flat mode occurs when the tire
inflation pressure is of/or below 14 psi (96 kPa). Once a
Run Flat tire reaches the run flat mode it has limited
driving capabilities and needs to be replaced immediately.
A Run Flat tire is not repairable.
It is not recommended driving a vehicle loaded at full
capacity or to tow a trailer while a tire is in the run flat
mode.
See the tire pressure monitoring section for more informa-
tion.
Tire Spinning
When stuck in mud, sand, snow, or ice conditions, do not
spin your vehicle’s wheels above 30 mph (48 km/h) or for
longer than 30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In Case Of Emer-
gency” for further information.
