injury, or death.
• Do not wear loose clothing or jewelry such as rings, watches, chains, etc., when servicing the vehicle.

• 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 14).
• To avoid unintentionally starting the vehicle disconnect battery and spark plug (Gas only) wires. See

• 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.
• When servicing the vehicle with part of the vehicle on jack stands, do not operate the engine with the
Forward/Reverse handle in either the FORWARD or REVERSE position. The all-wheel drive system will
