To prevent the fuse from being blown, do not use the power point(s)
over the vehicle capacity of 12 VDC/180W. If the power point or cigar
lighter socket is not working, a fuse may have blown. Refer to
Fuses and
relays
in the
Roadside Emergencies
chapter for information on
checking and replacing fuses.
To have full capacity usage of your power point, the engine is required to
be running to avoid unintentional discharge of the battery. To prevent
the battery from being discharged:
do not use the power point longer than necessary when the engine is
not running,
do not leave battery chargers, video game adapters, computers and
other devices plugged in overnight or when the vehicle is parked for
extended periods.

Connecting and disconnecting a trailer with air suspension and air
suspension dump switch (if equipped)
When connecting to a trailer:
Press the lower portion of the dump switch to exhaust air from the air
suspension system.
After making the connection to the trailer, press the upper portion of
the dump switch, then raise the landing gear.
When disconnecting the trailer:
Lower the landing gear, then press the lower portion of the dump
switch.
Disconnect the brake hoses, trailer-side and rear light connectors,
then pull the release lever on the fifth-wheel.
The upper portion of the dump switch must be pressed before operating
with a trailer or operating in the bobtail mode.
Suspension conversions
It is not recommended, or approved, that suspension conversions be
performed. However, it is understood that, on occasion, aftermarket
add-on suspensions are installed by others on the truck chassis which
allow operator control for weight transfer from other axles (i.e., air lift
axles).
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.
BRAKE-SHIFT INTERLOCK
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents the gearshift lever from being moved from P (Park)
when the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of P (Park) with the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or the vehicle’s brake lamps are not operating properly. Refer
to
Fuses and relays
in the

AUTOMATIC TRANSMISSION OPERATION (IF EQUIPPED)
Main transmission, auxiliary transmission, transfer case and power
take-off (PTO) control shift patterns can be found on a placard or decal
on the driver’s sun visor, on the instrument panel or on the shift control
itself.
The main transmission control is used to select the various gear ratios or
speeds of the transmission. Selecting D (Direct Drive), does not change
the transmission gear ratio, but is used where the gear ratios in the main
transmission are adequate to handle the vehicle operation.
If the transmission fails to shift properly, check the inline 10A fuse
located in the battery cables above the battery.
WARNING:
Hold the brake pedal down while you move the
gearshift lever between positions. If you don’t hold the brake
pedal down, your vehicle may move unexpectedly and cause property
damage, personal injury or death.

If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time; this minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover

Inline fuses
Your vehicle may have several inline fuses located in/on the battery
cables located in the battery box depending on application.
All Allison transmission equipped vehicles have a 10 Amp fuse located
in the clean power cables located in the battery box.
All vehicles have a 30 Amp fused located in the clean power cables
located in the battery box.
All vehicles equipped with an Eaton transmission have a 30 Amp fuse
located in the clean power cables located in the battery box.
All Hydraulic brake equipped vehicles have a 40 Amp fuse located in
the clean power cables located in the battery box and in addition
another 30 Amp fuse located in a fuse holder just above the power
distribution center located in the vehicles engine compartment.
JUMP STARTING
WARNING:
The gases around the battery can explode if
exposed to flames, sparks, or lit cigarettes. An explosion could
result in injury or vehicle damage.
WARNING:
Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission
vehicle. Automatic transmissions do not have push-start
capability. Attempting to push-start a vehicle with an automatic
transmission may cause transmission damage.
Before connecting a fast-charger, booster battery or installing a new
battery, make sure the ground polarities of the fast-charger, booster
battery or alternator (when installing a battery) are matched to the
ground polarity of the vehicle battery. Improper usage of the
fast-charger, hook-up of booster battery or installation of a new battery
can cause damage to the electrical system or to the alternator. Do not
attempt to polarize the alternator.

If you see any corrosion on the battery or terminals, remove the cables
from the terminals and clean with a wire brush. You can neutralize the
acid with a solution of baking soda and water.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time; this minimizes the discharge of your battery
during storage.
If the engine cranks but does not start, remove the battery box cover
and check the 40A inline fuse located on the battery cable above the
battery.
WARNING:
Batteries normally produce explosive gases which
can cause personal injury. Therefore, do not allow flames, sparks
or lighted substances to come near the battery. When working near the
battery, always shield your face and protect your eyes. Always provide
proper ventilation.
WARNING:
When lifting a plastic-cased battery, excessive
pressure on the end walls could cause acid to flow through the
vent caps, resulting in personal injury and/or damage to the vehicle or
battery. Lift the battery with a battery carrier or with your hands on
opposite corners.
WARNING:
Keep batteries out of reach of children. Batteries
contain sulfuric acid. Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the battery to protect against
possible splashing of acid solution. In case of acid contact with skin or
eyes, flush immediately with water for a minimum of 15 minutes and
get prompt medical attention. If acid is swallowed, call a physician
immediately.
WARNING:
Battery posts, terminals and related accessories
contain lead and lead compounds.
Wash hands after handling.
