Check your owners manual for your type of driving.

3-5 months/3-5k miles for conventional oil, or 5-7 months/5-7k miles for synthetic oil.

Your vehicle is equipped with an oil life monitoring system that will tell you when the oil needs to be changed. This system will take into account your normal driving patterns. However, it is important to check your oil level regularly (at least once a month) as the engine will burn some oil over time and a warning light may not illuminate if the level is too low.
