• Only trained technicians should service or repair the vehicle. Anyone doing even simple
repairs or service should have knowledge and experience in electrical and mechanical repair.
The appropriate instructions must be used when performing maintenance, service, or
accessory installation.
• If any problems are found during scheduled inspection or service, do not operate vehicle until
repairs are made. Failure to make necessary repairs could result in fire, property damage,
severe personal injury, or death.
• Do not wear loose clothing or jewelry such as rings, watches, chains, etc., when servicing the
vehicle.
• Turn key switch to the OFF position, remove the key, place the Forward/Reverse handle in the
NEUTRAL position and chock the wheels prior to servicing.
• Moving parts: Do not attempt to service vehicle while engine is running.
• Hot! Do not attempt to service hot engine or exhaust system. Failure to heed this warning
could result in severe burns.
• For vehicles with cargo beds, remove all cargo before raising the bed or servicing the vehicle.
If the vehicle is equipped with a prop rod, ensure that it is securely engaged while bed is
raised. Do not close bed until all persons are clear of cargo bed area. Keep hands clear of all
crush areas. Do not drop cargo bed; lower gently and keep entire body clear. Failure to heed
this warning could result in severe personal injury or death.
• Do not work on vehicle powertrain or under cargo bed when it is loaded.
• Gasoline vehicles only: Turn fuel shut-off valve to the closed (OFF) position (Figure 12,
Page 26).
• To avoid unintentionally starting the vehicle:
- Disconnect battery cables, negative (–) cable first (Figure 1, Page 7).

• If wires are removed or replaced make sure wiring and wire harness are properly routed and
secured. Failure to properly route and secure wiring could result in vehicle malfunction,
property damage, personal injury, or death.
• Lift only one end of the vehicle at a time. Use a suitable lifting device (chain hoist or hydraulic
floor jack) with 1000 lb. (454 kg) minimum lifting capacity. Do not use lifting device to hold
vehicle in raised position. Use approved jack stands of proper weight capacity to support the
vehicle and chock the wheels that remain on the floor.
