Inspection Procedure

    Important: In order to obtain an accurate indication of the fluid level, the rear drive module priming procedure must be performed prior to fluid level inspection.

  1. Prime the rear drive module in the service stall:
    2. 1.1. Raise and support the vehicle so that all wheels are off of the ground. Refer to Lifting and Jacking the Vehicle in General Information.
    1.2. Start the engine and place transmission in a forward gear.
    1.3. Slowly apply the park brake until the rear wheels stop rotating.
    1.4. Carefully accelerate the engine until the rear wheels begin to rotate.

            Important: Do not exceed 5 seconds of park brake apply while vehicle is in gear and the engine is running to avoid overheating of the rear drive module.

    1.5. Continue allowing the rear wheels to rotate for 5 seconds.
    1.6. Release the accelerator and apply the brakes.
    1.7. Place transmission in park or neutral and turn the engine OFF.
    1.8. Release the park brake.
    1.9. Raise the vehicle fully.
  2. Alternatively, prime the rear drive module by driving the vehicle on a flat, paved surface in a tight, 360 degree circle for 3 consecutive revolutions at 8 km/h (5 mph).
