ý WARNING
- Gasoline vehicles only: Disconnect the spark plug wires from the spark plugs.
• 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 engage any wheel(s), front or rear, with traction. See Figure 2 on page 9.

maintenance and service manual.

maintenance procedures should be performed more often than recommended in the Periodic Ser-
vice and Lubrication Schedule.
Both the Periodic Service Schedule and the Periodic Lubrication Schedule must be followed to
keep vehicle in optimum operating condition.
