Depending on the engine, the oil dipstick may be in a different location.

When checking the oil level: Х park the vehicle on a level surface.

Х the engine should be switched off for approximately five minutes if the engine is at normal operating temperature.

Х if the engine is not at normal operating temperature, e.g. if the engine was only started briefly: wait about 30 minutes before carrying out the measurement.
