  3. 03Signal and move to a safe, level shoulder well away from traffic.
  4. 04Inspect for damage to air lines, wiring, mud flaps, and adjacent tires.
  5. 05Call for tire service rather than changing a drive or steer tire roadside.

Overheating

  1. 01Reduce load on the engine and shut off the engine brake and cruise.
  2. 02Turn the heater to full hot and high fan to shed heat.
  3. 03Find a safe place to stop and idle down before shutting off.
  4. 04Never open a hot pressurized cooling system.
  5. 05Check for coolant leaks, belt condition, fan operation, and debris on the radiator.

Low oil pressure warning

  1. 01Treat this as an immediate stop condition.
  2. 02Signal, move safely off the roadway, and shut the engine down.
  3. 03Do not continue driving to the next exit or truck stop.
  4. 04Check oil level once the engine is safely shut down.
  5. 05Call for a qualified technician before restarting the engine.

Low air pressure warning

  1. 01Slow down immediately and plan a stop before the warning turns into a spring-brake application.
  2. 02Get fully off the roadway while you still have service brakes.
  3. 03Set the parking brakes and listen for audible air leaks.
  4. 04Inspect glad hands, air lines, and the air dryer for obvious failures.
  5. 05Do not move the truck with a known air-system defect.

Brake problem

  1. 01Reduce speed using engine braking and downshifting where safe.
  2. 02Look for an escape ramp or runaway lane on a grade.
  3. 03Stop as soon as you have a safe, level location off the roadway.
  4. 04Do not adjust, disable, or bypass any brake component.
  5. 05Brakes are safety-critical. Call a qualified technician.

Electrical fire or burning smell

  1. 01Stop safely and shut the engine down.
  2. 02Turn off the battery disconnect if it is safely reachable.
  3. 03Call emergency services for any visible flame or heavy smoke.
  4. 04Do not reset breakers or reconnect a circuit that failed.
  5. 05Have the circuit diagnosed before returning the truck to service.

Fuel leak

  1. 01Shut the engine down and eliminate all ignition sources.
  2. 02Do not smoke, use a phone flashlight near vapors, or operate switches near the leak.
  3. 03Contain the spill if you can do so safely and report it as required.
  4. 04High-pressure fuel systems are a serious hazard. Do not attempt repairs.
  5. 05Call a qualified technician and, if required, emergency services.

  2. 02Stop in a safe location and let the system cool completely.
