roads, in heavy traffic or when the
road surface is slippery. This could
result in loss of vehicle control, serious
injury or death. When you are going downhill, your
vehicle speed may increase above
the set speed. The system will not
apply the brakes but a warning displays.
Failure to follow this warning could result
in serious personal injury or death. Note:
Cruise control will disengage if the
vehicle speed decreases more than 10 mph
(16 km/h) below the set speed while driving
uphill. The cruise controls are on the steering
wheel.

AIR SUSPENSION (If Equipped)
Note: Do not operate your vehicle without
air in the suspension springs. Operating your
vehicle without air in the suspension springs
damages the suspension, degrades ride
performance and may cause property
damage.
The air suspension system automatically
adjusts to different loads to maintain a
constant frame height, allows for ease of
vehicle loading, provides improved vehicle
ride, and increased driver comfort.
Air Suspension Dump Button Note:
The suspension dumps air when the
ignition is in the accessory or on position,
but fills only when the ignition is in the on
position.
A button located on the instrument panel
controls the system. It operates only when
the ignition is in the accessory or on
position and the air tanks have sufficient
pressure to fill the air springs. When you
turn off the ignition, the suspension
remains in whatever state it was last set.
Pressing and holding the button for two
seconds exhausts air from the air springs,
lowering the frame for loading. Pressing
and holding the button for two seconds
fills the air springs so your vehicle remains
at normal ride height. System Indicator Light
The air suspension indicator light
illuminates when using the button to
release air pressure in the rear air springs.
Never drive your vehicle when the warning
lamp is illuminated and there is low (or no)
air pressure in the springs.
Connecting and Disconnecting a
Trailer with Air Suspension and Air
Suspension Dump Button
When connecting to a trailer:
•
Press and hold the button for two
seconds to exhaust air from the air
suspension system.
• Press and hold the button for two
seconds, and then raise the landing
gear after making the connection to
the trailer.
When disconnecting the trailer:
• Lower the landing gear, and then press
and hold the button for two seconds.
• Disconnect the brake hoses, trailer-side
and rear light connectors, then pull the
release lever on the fifth wheel.
You must fill the air springs before
operating with a trailer or operating in the
bobtail mode.
Suspension Conversions WARNING
When operating a loaded vehicle, the
driver must keep all adjustable axles
on the ground at all times, supporting
their share of the vehicle ’s load. Failure to
do so can overload other axles, tires,
wheels, springs, steering components,
brakes and frames, resulting in early
component failure, loss of vehicle control,
possible property damage and personal
injury. 136

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See Fuses
(page 161).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
•
Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See
Load Limit (page
135).

ESSENTIAL TOWING CHECKS
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue.
Safety Chains
Note: Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations. The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Trailer Lamps
WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position
P or position N to
aid engine and transmission cooling
and to help air conditioning
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
140

•
Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with
the Tow/Haul feature, use this feature
when towing. This provides engine
braking and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
FIFTH WHEEL OPERATION WARNINGS
Failure to follow the fifth wheel
manufacturer
’s instructions for
hooking and unhooking as well as
sliding the fifth wheel could result in an
accident, personal injury or death. When the tractor and trailer are
parked unattended, the trailer brake
hand control should never be used
to apply the brake, since air may leak from
the system, allowing vehicle movement,
resulting in possible property damage,
personal injury or death. Before hook-up, make sure:
•
The fifth wheel jaws are fully open.
• The fifth wheel is fully tilted back to
prevent body damage when the tractor
is backed under a trailer.
• You block the trailer wheels and adjust
and apply the trailer spring brakes.
Never chase a trailer.
• The brake hoses and light cords are
clear of the fifth wheel. Hook-up
1. Back the tractor squarely under the
trailer, engaging the fifth-wheel jaws
on the kingpin. Always back up slowly;
make sure the trailer is neither too high
nor too low. Avoid backing under the
trailer from an angle.
2. Connect the service and emergency brake hoses and trailer light connector.
3. Inspect the jaws of the fifth wheel to be sure they have fully closed on the
trailer kingpin and the trailer plate is
resting securely on the fifth wheel.
4. Make sure the coupler release lever is in the locked position.
5. Charge the trailer brake system. Set the trailer brakes, with either the hand
valve or tractor protection valve. Pull
against the trailer for an extra check of
proper hook-up. Do not pull hard
enough to damage or strain the
equipment.
6. Set the tractor parking brakes and fully
raise the trailer landing gear.
7. Check the operation of all trailer lights
and correct any lights that may be
faulty.
Un-hook
1. Try to keep the tractor and trailer in a straight line.
2. Apply the parking brakes.
3. Lower the trailer landing gear, making sure it is on solid, level ground. The
weight of the trailer is to be on the
landing gear.
4. Block the trailer wheels.
5. Disconnect the brake hoses and light cords. Be sure hoses and cords are
clear.
6. Pull coupler release lever to disengage
the fifth wheel jaws.
141

7. Release the tractor parking brakes.
8.
Pull out from the trailer slowly, allowing
the landing gear to take the load
gradually.

Parking
WARNING
When parking your vehicle, do not
leave the transmission in gear; if the
key is in the on position and the
vehicle rolls, the engine could start. Failure
to follow these instructions could result in
an unattended vehicle moving, possibly
causing personal injury or property
damage. Always use the parking brake. When
parking on a grade, block the wheels and
turn the front wheels to one side so that if
your vehicle rolls, the front tires act against
the curb to stop your vehicle. The front
wheels are more effective at stopping a
rolling vehicle than the rear wheels.
ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
•
Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds (traveling
at 55 mph [88 km/h] uses 15% less
fuel than traveling at 65 mph [105
km/h]).
• Keep the tires properly inflated and use
only the recommended size. •
Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner or front
defroster.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).
• Driving with the wheels out of
alignment.
Conditions
• Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 8– 10
miles (12 –16 kilometers) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
