Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Wear safety gloves and goggles.

2. Change Engine Oil

Sub-steps:
1. Raise the vehicle using a jack and secure it on jack stands.
2. Place a drain pan under the oil pan and remove the oil drain plug using a wrench.
3. Allow the old oil to completely drain into the pan.
4. Replace the oil drain plug and torque to the manufacturer's specifications (typically around 25 ft-lbs).
5. Remove the old oil filter using an oil filter wrench.
6. Apply a small amount of new oil to the rubber gasket of the new oil filter, then install it.
7. Fill the engine with new oil (consult the owner's manual for the correct oil type and capacity, typically 0W-20).

3. Rotate Tires

Sub-steps:
1. Loosen the lug nuts on all four wheels while the vehicle is still on the ground.
2. Lift the vehicle and secure on jack stands.
3. Remove the lug nuts and tires from the front axle.
4. Move the front tires to the rear and the rear tires to the front in a crisscross pattern (left rear to right front, and vice versa).
5. Reinstall the tires and hand-tighten the lug nuts.
6. Lower the vehicle back to the ground and torque the lug nuts to the manufacturer's specifications (usually 80 ft-lbs).
