• Place the gearshift lever in position P (if equipped) or neutral to aid
in engine and transmission cooling and air conditioning efficiency
during hot weather while stopped in traffic.
• Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
• 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.
• Allow more distance for stopping with a trailer attached. Anticipate
stops and brake gradually.
FIFTH WHEEL OPERATION
WARNING: 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.
WARNING: 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.
