PRINCIPLES OF OPERATION
Cruise control lets you maintain a set speed without keeping your foot
on the accelerator pedal.
USING CRUISE CONTROL
WARNING:Do not use cruise control in heavy traffic, on
winding roads or when the road surface is slippery. This could
result in loss of vehicle control, serious injury or death.
WARNING:When you are going downhill, your vehicle speed
may increase above the set speed. The system will not apply the
brakes. Change down a gear to assist the system in maintaining the set
speed. Failure to do so could result in loss of vehicle control, serious
injury or death.
Note:Cruise control disengages if your vehicle speed decreases more
than 10 mph (16 km/h) below your set speed while driving uphill.
The cruise controls are located on
the steering wheel.
Switching On Cruise Control
Press and releaseON.
The indicator turns on in the instrument cluster.
Setting a Speed
1. Accelerate to the desired speed.
2. Press and releaseSET ACCEL.

•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, air
conditioning condenser and accessories clean to avoid dirt build-up.
•You may experience above normal coolant temperatures while driving
in a transmission gear ratio that lugs the engine. To correct this
problem, increase engine speed by downshifting into the next lower
gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering your vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate your vehicle with the power steering pump fluid level
below the ADD mark on the MAX COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by an authorized dealer.
•Low power steering pump fluid levels may cause heavy or uneven
steering efforts. Check the power steering pump fluid level before
seeking service from an authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX HOT side of the power steering reservoir dipstick, as this
may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer your vehicle manually, but it takes more effort.

If the steering wanders or pulls, check for:
•Underinflated tire(s) on any wheel(s)
•Uneven vehicle loading
•High crown in center of road
•High crosswinds
•Wheels out of alignment
•Loose or worn suspension components.
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 Switch
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 switch located in the overhead
switch pack 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 the lower portion of the switch exhausts air from the air
springs, lowering the frame for loading. Pressing the upper portion of the
switch fills the air springs so your vehicle remains at normal ride height.
System Indicator Light
The air suspension indicator light illuminates when using the
switch to release air pressure in the rear air shocks. Never
drive your vehicle when the warning lamp is illuminated and
there is low (or no) air pressure in the shocks.

Connecting and Disconnecting a Trailer with Air Suspension and
Air Suspension Dump Switch
When connecting to a trailer:
•Press the lower portion of the switch to exhaust air from the air
suspension system.
•Press the upper portion of the switch, and then raise the landing gear
after making the connection to the trailer.
When disconnecting the trailer:
•Lower the landing gear, and then press the lower portion of the
switch.
•Disconnect the brake hoses, trailer-side and rear light connectors,
then pull the release lever on the fifth wheel.
You must press the upper portion of the switch 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.
We do not recommend performing, or approve of, suspension
conversions. However, we understand that, on occasion, others install
aftermarket add-on suspensions on the truck chassis that allow operator
control for weight transfer from other axles (such as air lift axles).

provided by the service manual. Hydraulic brake systems are
power-assisted. There is a great reduction in braking capabilities
without engine assist.
•Proper fluid level. The level should be at the bottom edge of the ring
on each reservoir fill port. Do not fill the master cylinder to the top of
the reservoir. If fluid level requires attention to maintain a proper
master cylinder level, this is an indication of either severe operation
(pad wear) or fluid leakage. A more frequent and thorough brake
inspection is required.
•Brake lines, hoses and fittings. Repair or replace brake line tubes,
hoses or fittings as required. Inspect these components every
4000 miles (6000 kilometers):
•Lines for kinks, dents, corrosion or rupture.
•Hoses for abrasions, kinks, soft spots or rupture, collapse, cracks,
twists or loose frame supports. When replacing a hose, be sure
there is adequate clearance to the hose to avoid an abrasion to the
new hose.
•All connections for leaks.
Driveline Parking Brake
WARNING:Use wheel chocks and exercise caution when
inspecting under the vehicle. A vehicle roll-away could result in
property damage, personal injury or death.
A qualified technician should adjust the parking brake and keep to the
instructions in the service manual.
Steering System
WARNING:Failure to maintain the steering system in proper
condition can cause reduced steering ability resulting in property
damage, personal injury or death.
Note:Have any steering problems immediately corrected by a qualified
service technician.
Ask your service technician to examine the steering mechanism. Only
minor adjustments may be necessary. Regular inspections should include:
•Checking the tie rod, drag link end clamp bolts and ball joints for
proper tightness.
•Checking for installation and spread of cotter pins and tightness of
nuts at both ends of the tie rod and drag link.
