Oil Check

We recommend that you check the engine oil level every time you refuel.
Park the vehicle on level ground.
Turn off the power system. You can check the oil level without the engine having run beforehand. If the engine has been running, wait approximately three minutes before you check the oil.

1. Remove the dipstick (orange).
2. Wipe the dipstick with a clean cloth or paper towel.
3. Insert the dipstick back all the way into its hole.
   
4. Remove the dipstick again, and check the level. It should be between the upper and lower marks. Add oil if necessary.

If the oil level is near or below the lower mark, slowly add oil, being careful not to overfill.

Adding Engine Oil

1. Unscrew and remove the engine oil fill cap.
2. Add oil slowly.
3. Reinstall the engine oil fill cap, and tighten it securely.
4. Wait for three minutes and recheck the engine oil dipstick.

NOTICE
Do not fill the engine oil above the upper mark. Overfilling the engine oil may result in leaks and engine damage.
If any oil spills, wipe it away immediately. Spilled oil may damage the engine compartment components.

Changing the Engine Oil and Oil Filter

You must change the engine oil and oil filter regularly in order to maintain the engine’s lubrication. The engine may be damaged if they are not changed regularly.
Turning the power system on automatically starts the engine if the High Voltage battery charge level gauge shows two segments or less.

Change the oil and filter in accordance with the maintenance message on the driver information interface.
