damage.If the engine is
overfilled, some oil must be
removed from the engine by a
qualified service technician.
7. Put the indicator back in and ensure it is fully seated.

2. If the engine oil level is not within the normal operating range, add
only certified engine oil of the recommended viscosity. Remove the
engine oil filler cap and use a funnel to pour the engine oil into the
opening.
3. Recheck the engine oil level. Make sure the oil level is not above the
normal operating range on the engine oil level indicator (dipstick).
4. Install the indicator and ensure it is fully seated.
5. Fully install the engine oil filler cap by turning the filler cap clockwise
until three clicks can be heard.

Your vehicle’s rear axle is filled with a synthetic rear axle lubricant and is
considered lubricated for life. These lubricants do not need to be
checked or changed unless a leak is suspected, service is required or the
axle assembly has been submerged in water. The axle lubricant should
be changed any time the rear axle has been submerged in water.
3Capacity is approximate and will vary due to second stage manufacturer
completion of HVAC system. Fill to Hot/Cold Lines on reservoir.
